Description

  The present invention relates to an infected candidate identification device, an infected candidate identification method, and an infected candidate identification program.

  In recent years, the aging of hospitalized patients, frequent use of immunosuppressants, introduction of highly invasive medical care, etc. have increased the number of easily infectious patients, facilitating the establishment of infection, and the importance of measures against nosocomial infections has increased. ing. Infectious routes include airborne infection such as droplet infection and droplet nuclear infection. In addition, measures against nosocomial infection include identifying and isolating infected persons.

  As a prior art, for example, there is one that distributes information to a user in accordance with not only the position of the user of the mobile terminal device but also the behavior of the user.

JP 2012-64138 A

  However, in the prior art, it is difficult to narrow down those who may be infected. For example, it is conceivable to isolate a person who was in the same place (ward, ward, etc.) as an infected person as a person who may be infected. However, if all the people who were in the same place are candidates for infection, the number of candidates will increase, and the impact of isolation will increase.

  In one aspect, an object of the present invention is to provide an infected candidate identification device, an infected candidate identification method, and an infected candidate identification program that can narrow down infection candidates.

  According to one aspect of the present invention, when it is detected that an infected person has performed an action of causing droplets, the storage unit stores position information indicating the correspondence between the position of the person to be inspected and the time. When the infected person performs the operation, it is determined whether or not the inspected person is in the place where the infected person has performed the operation, and when it is determined that the inspected person exists, the inspected person An infected candidate identification device, an infected candidate identification method, and an infected candidate identification program that output identification information of a person are proposed.

  According to one aspect of the present invention, there is an effect that candidates for infection can be narrowed down.

  Embodiments of an infected candidate identification device, an infected candidate identification method, and an infected candidate identification program according to the present invention will be described below in detail with reference to the drawings.

(Embodiment)
FIG. 1 is an explanatory diagram of an example of the infected candidate identification method according to the embodiment. In FIG. 1, an infected candidate identification device 101 is a computer that has a storage unit 110 and identifies a candidate for infection. The storage unit 110 stores position information indicating a correspondence relationship between the position of the subject and the time.

  A person to be inspected is a person to be inspected for infection. The examinee is, for example, a hospital patient (for example, an inpatient, an outpatient, etc.), a patient-related person, a medical worker such as a doctor or a nurse, and a trader. The position information is information that specifies, for example, the position of the subject and the time (for example, date and time) when the position was measured.

  Here, as a countermeasure for preventing nosocomial infection in medical institutions such as hospitals and medical malls, it is effective to identify and isolate infected persons. An infected person is a person who has entered a body with a pathogen and is capable of infecting other individuals by air infection such as droplet infection or droplet nuclear infection.

  On the other hand, those who come into contact with an infected person (including a latently infected person) before isolation may be infected with a pathogen. Therefore, in order to prevent further infection, it is necessary to identify a person who has contacted the infected person through, for example, a hearing survey and take appropriate actions such as medical examination and treatment. However, it takes time and effort to identify the person who has contacted the infected person through interviews, and there is a high possibility that a specific omission will occur.

  It is also conceivable to isolate a person who is in the same place as the infected person (for example, a ward, a hospital room, etc.) as a person who may be infected. However, if all the people who were in the same place are candidates for infection, the number of candidates will increase, and the impact of isolation will increase.

  Therefore, in the present embodiment, when an infected person performs an action that causes a droplet that causes air infection such as coughing and sneezing, the person who is present is identified as an infection candidate. A method will be described. Hereinafter, a processing example of the infected candidate specifying apparatus 101 will be described.

  In the example of FIG. 1, the infected person A is a person who can infect other individuals by air infection such as droplet infection or droplet nuclear infection. In addition, the inspected persons B and C are persons to be inspected for the presence or absence of infection. The infected person A has a terminal device 102. In addition, the examinees B and C have terminal devices 103 and 104, respectively.

  The terminal devices 102 to 104 have a function of measuring the position of the own device. For example, the terminal devices 103 and 104 periodically measure the position of the own device, that is, the positions of the inspected persons B and C, and transmit the position information 120 and 130 to the infected candidate specifying apparatus 101. The position information 120 is information indicating a correspondence relationship between the position of the subject B and the time when the position is measured. The position information 130 is information indicating a correspondence relationship between the position of the subject C and the time when the position is measured.

  When receiving the position information 120 and 130 from the terminal devices 103 and 104, the infected candidate specifying apparatus 101 stores the received position information 120 and 130 in the storage unit 110. Thereby, the position information 120 and 130 that can specify the temporal change of the positions of the examinees B and C can be accumulated in the storage unit 110.

  In addition, the terminal device 102 has a function of detecting an operation that causes splashing. Here, the operation that generates the splash is, for example, sneezing or coughing. Specifically, for example, the terminal device 102 detects an operation that causes splashes such as sneezing and coughing from the amount of movement based on the output value of the acceleration sensor. In addition, the terminal device 102 may detect an operation that causes splashes such as sneezing and coughing by analyzing sound measured by a microphone, for example.

  (1) The infected candidate identification device 101 detects that the infected person has performed an operation of causing splashing. In the example of FIG. 1, the infected candidate specifying apparatus 101 detects that the infected person A has performed an action of causing a splash when the splash action information 140 is acquired from the terminal apparatus 102, for example. The splash operation information 140 is, for example, information indicating a position p and a time t at which the infected person A has performed an operation of causing a splash.

  In addition, for example, the infected candidate specifying apparatus 101 periodically acquires an output value of an acceleration sensor or the like from the terminal apparatus 102, and performs an operation in which the infected person A generates droplets from the amount of movement based on the output value. It may be determined whether or not.

  (2) When the infected candidate identifying apparatus 101 detects that the infected person has performed an action of causing droplets, the infected person refers to the storage unit 110, and when the infected person performs the action, the infected person It is determined whether or not there is an examinee at the place where the operation is performed.

  Specifically, for example, the infected candidate identification apparatus 101 has the subject to be inspected at the place where the infected person performed the operation until a predetermined time has elapsed from the time when the infected person performed the operation. It may be determined whether or not. As a result, the subject was in the same place as the infected person (for example, a hospital room, examination room, corridor, waiting room, entrance / exit, etc.) within the period expected to be affected by the splashes caused by coughing or sneezing of the infected person. It can be determined whether or not.

  In addition, for example, the infected candidate identification device 101 determines whether or not the inspected person is within a predetermined range from the position where the infected person performs the operation at the time when the infected person performs the operation. Also good. Thus, when the infected person coughs or sneezes, it can be determined whether or not the subject is within the range where the influence of the splashes scattered by the infected person's coughing or sneezing is expected.

  The predetermined time and the predetermined range described above can be arbitrarily set. For example, the range of scattering differs depending on the vital capacity. Moreover, vital capacity changes with sex, age, etc. of an infected person. For this reason, the predetermined time and the predetermined range may be set according to attributes such as sex and age of the infected person, for example. In addition, the infectivity of pathogens may vary depending on the type of disease. For this reason, the predetermined time and the predetermined range may be set in accordance with, for example, the type of illness that the infected person suffers from.

  Here, as an example, at the time t when the infected person identifying apparatus 101 performs the operation of causing the infected person A to generate droplets, the inspected person B falls within a predetermined range R including the position p where the infected person A has performed the action. , C is assumed to be determined. In FIG. 1, arrows 150, 160, and 170 represent movement paths of the infected person A and the inspected persons B and C, respectively.

  In the example of FIG. 1, of the inspected persons B and C, the inspected person B is within a predetermined range R at time t. For this reason, the to-be-infected candidate specifying apparatus 101 determines that the inspected person B was within the predetermined range R at the time t when the infected person A performed the operation of causing the splash. On the other hand, the infected candidate specifying apparatus 101 determines that there is no subject C in the predetermined range R at the time t when the infected person A performs the operation of causing splashing.

  (3) When it is determined that there is a person to be inspected, the candidate identifying apparatus 101 outputs identification information of the person to be inspected. In the example of FIG. 1, the infected candidate identification device 101 outputs, for example, infected candidate information 180 including identification information of the person B to be inspected. The infected candidate information 180 may include, for example, identification information of the infected person A, and information specifying the position p and the time t at which the infected person A has performed an operation of causing splashing.

  Thus, according to the infected candidate identification apparatus 101, when the infected person coughs or sneezes, the person to be inspected who is in the same place as the infected person can be narrowed down as a candidate who may be infected. . For example, according to the infected candidate information 180, the subject B can be identified as a candidate who may be air-infected near the position p at time t due to coughing or sneezing of the infected person A.

(System configuration example of infected candidate identification system 200)
Next, a system configuration example of the infected candidate identification system 200 according to the embodiment will be described. Here, the case where the infected candidate identification system 200 is applied to the medical institution M will be described as an example. The medical institution M is, for example, a hospital or a medical mall.

  FIG. 2 is an explanatory diagram showing a system configuration example of the infected candidate identification system 200. In FIG. 2, an infected candidate identification system 200 includes an infected candidate identification device 101, a management device 201, access points AP1 to APm (m: a natural number of 2 or more), and terminal devices T1 to Tn (n: 2 or more natural numbers).

  In the infected candidate identification system 200, the infected candidate identification device 101, the management device 201, and the access points AP1 to APm are connected via a wired or wireless network 210. The network 210 is, for example, a local area network (LAN), a wide area network (WAN), or the Internet.

  The infected candidate specifying apparatus 101 includes a mover information DB (DataBase) 220, a parameter table 230, and an infected candidate table 240, and specifies an infection candidate from the inspected person. The inspected person is, for example, a patient of the medical institution M, a patient related person, a medical worker such as a doctor or a nurse, an entry / exit trader or the like.

  The storage contents of the mover information DB 220, the parameter table 230, and the infected candidate table 240 will be described later with reference to FIGS.

  The management device 201 is a computer used by an administrator of the infected candidate identification system 200, and is, for example, a PC (personal computer), a tablet PC, a smartphone, or the like. The administrator of the infected candidate identification system 200 is, for example, a doctor or a nurse of the medical institution M.

  In addition, in the management apparatus 201, for example, when an infected person is designated by an operation input by the administrator, infected person information including a user ID that uniquely identifies the designated infected person is transmitted to the infected candidate specifying apparatus 101. Sent. For example, when it is detected that a subject is infected with a pathogen, the subject is designated as an infected person. The infected person information may include, for example, the disease name, sex, age, etc. of the infected person.

  In addition, for example, there is a case where it is possible to specify the time when an infected person is infected with a pathogen by interviewing an infected person with a doctor. In such a case, the management apparatus 201 may further transmit infected person information including the infection time when the infected person was infected with the pathogen to the infected candidate specifying apparatus 101.

  The access points AP1 to APm are wireless LAN access points installed at various locations in the medical institution M (for example, hospital rooms, examination rooms, corridors, waiting rooms, reception lobbies, entrances, etc.). In the following description, an arbitrary access point among the access points AP1 to APm may be expressed as “access point APj”, and a wireless communication range of the access point APj may be expressed as “communication area Aj” (j = 1, 2, ..., n).

  The terminal devices T1 to Tn are computers used by examinees (including infected people). The terminal devices T1 to Tn are, for example, wearable terminals such as a pendant type, a batch type, and a wristband type that can be used while worn on the body or clothes. The terminal devices 102 to 104 illustrated in FIG. 1 correspond to the terminal devices T1 to Tn, for example.

  The terminal devices T1 to Tn can wirelessly communicate with the access point APj in the communication area Aj, and can be connected to the network 210 via the access point APj. In the following description, an arbitrary terminal device among the terminal devices T1 to Tn may be referred to as “terminal device Ti” (i = 1, 2,..., N).

  The terminal device Ti is lent out, for example, when the examinee visits the medical institution M, and is returned when the examinee returns from the medical institution. Further, for example, when the terminal device Ti is lent to the subject, the terminal device Ti is associated with the subject. For example, when the terminal device Ti is lent to the subject, a user ID that uniquely identifies the subject is input to the terminal device Ti.

  Further, the terminal device Ti has a function of measuring the position of the own device. Specifically, for example, the terminal device Ti receives a beacon signal transmitted from the access point APj and specifies the position of the access point APj capable of wireless communication. And terminal unit Ti measures the position of an own apparatus based on the position of identified access point APj and the field intensity of the received beacon signal.

  Further, the terminal device Ti has a function of detecting an operation that causes splashing. As described above, the action causing the splash is coughing or sneezing. Specifically, for example, the terminal device Ti detects an operation that causes splashes such as sneezing and coughing from the amount of movement based on output values of various sensors 403 shown in FIG.

  Further, the terminal device Ti transmits the moving person information to the infected candidate specifying apparatus 101. Here, the mover information includes, for example, a user ID, position information, and a splash flag. The user ID is identification information that uniquely identifies the subject who uses the terminal device Ti. The position information is information indicating the position of the terminal device Ti and the date and time when the position is measured. A splash flag is information which shows whether the operation | movement which produces a splash was detected.

  Specifically, for example, the terminal device Ti measures the position of its own device at regular intervals. The fixed time can be arbitrarily set, and is set to a time of about several seconds, for example. At this time, the terminal device Ti detects, for example, an operation that generates splashes based on output values of various sensors 403 (see FIG. 4 described later) for the latest fixed time.

  Then, each time the terminal device Ti measures the position of its own device, the terminal device Ti transmits location information indicating the position of its own device and mobile information including a splash flag to the infected candidate specifying device 101. Accordingly, it is possible to periodically upload the traveler information from the terminal device Ti to the infected candidate specifying device 101.

  The terminal device Ti may be capable of wireless communication with a base station (not shown) of the mobile communication network, for example. In this case, the terminal device Ti can be connected to the network 210 via the base station in a cell of a base station (not shown) of the mobile communication network. The terminal device Ti may be, for example, a smartphone, a mobile phone, a PHS (Personal Handy-phone System), or the like.

(Hardware configuration example of infected candidate identification apparatus 101)
FIG. 3 is a block diagram illustrating a hardware configuration example of the infected candidate specifying apparatus 101. In FIG. 3, the infected candidate specifying apparatus 101 includes a CPU (Central Processing Unit) 301, a memory 302, an I / F (Interface) 303, a disk drive 304, and a disk 305. Each component is connected by a bus 300.

  Here, the CPU 301 governs overall control of the infected candidate identification apparatus 101. The memory 302 includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), and a flash ROM. Specifically, for example, a flash ROM or ROM stores various programs, and a RAM is used as a work area for the CPU 301. The program stored in the memory 302 is loaded into the CPU 301 to cause the CPU 301 to execute the coded process.

  The I / F 303 is connected to the network 210 through a communication line, and is connected to other computers (for example, the management device 201, the access point APj, and the terminal device Ti illustrated in FIG. 2) via the network 210. The I / F 303 controls an internal interface with the network 210 and controls input / output of data from other computers. For example, a modem or a LAN adapter may be employed as the I / F 303.

  The disk drive 304 controls reading / writing of data with respect to the disk 305 according to the control of the CPU 301. The disk 305 stores data written under the control of the disk drive 304. Examples of the disk 305 include a magnetic disk and an optical disk.

  In addition to the above-described components, the infected candidate identification device 101 may include, for example, an SSD (Solid State Drive), a keyboard, a mouse, a display, and the like. The access point APj shown in FIG. 2 can also be realized by the same hardware configuration as that of the infected candidate specifying apparatus 101.

(Hardware configuration example of terminal device Ti)
FIG. 4 is a block diagram illustrating a hardware configuration example of the terminal device Ti. In FIG. 4, the terminal device Ti includes a CPU 401, a memory 402, various sensors 403, an I / F 404, a display 405, and a keypad 406. Each component is connected by a bus 400.

  Here, the CPU 401 governs overall control of the terminal device Ti. The memory 402 includes, for example, a ROM, a RAM, a flash ROM, and the like. Specifically, for example, a flash ROM or ROM stores various programs, and the RAM is used as a work area of the CPU 401. The program stored in the memory 402 is loaded on the CPU 401 to cause the CPU 401 to execute the coded process.

  The various sensors 403 are an acceleration sensor, a microphone, a gyro sensor, etc., for example. Further, the output values of the various sensors 403 are stored in the memory 402, and are used for detecting an operation that causes splashes such as coughing and sneezing, for example.

  The I / F 404 is connected to the network 210 via the access point APj (or a base station of the mobile communication network), and is connected to another computer (for example, the infected candidate identification device shown in FIG. 2) via the network 210. 101). The I / F 404 controls the interface between the network 210 and the own apparatus, and controls data input / output from other computers.

  A display 405 displays data such as a document, an image, and function information as well as a cursor, an icon, or a tool box. As the display 405, for example, a liquid crystal display, an organic EL (Electroluminescence) display, or the like can be used.

  The keypad 406 has keys for inputting characters, numbers, various instructions, etc., and inputs data. The keypad 406 may be, for example, a touch panel type input pad or a numeric keypad.

  In addition to the above-described components, the terminal device Ti has, for example, a GPS unit that receives radio waves from a GPS (Global Positioning System) satellite and outputs information indicating the current position of the terminal device Ti. Also good. In this case, the terminal device Ti may measure the position of its own device by the GPS unit.

  Also, the management apparatus 201 shown in FIG. 2 can be realized by the same hardware configuration as the terminal apparatus Ti. However, the management apparatus 201 may include a disk drive, a disk, a keyboard, a mouse, and the like. Further, the management apparatus 201 does not have to include the various sensors 403.

(Storage contents of various DBs 220, 230, 240)
Next, the stored contents of various DBs 220, 230, and 240 included in the infected candidate specifying apparatus 101 will be described with reference to FIGS. The various DBs 220, 230, and 240 are realized by storage devices such as the memory 302 and the disk 305 shown in FIG.

  FIG. 5 is an explanatory diagram showing an example of the stored contents of the traveler information DB 220. In FIG. 5, the mover information DB 220 includes fields for user ID, position information (t, X, Y, Z), and a splash flag. By setting information in each field, mover information (for example, move Person information 500-1 to 500-18) is stored as a record.

  Here, the user ID is identification information that uniquely identifies the subject who uses the terminal device Ti. In the following description, an inspected person who uses the terminal device Ti may be referred to as “inspected person Pi”. The position information (t, X, Y, Z) indicates the position of the terminal device Ti in the medical institution M and the date and time when the position is measured. Here, the position information (t) indicates the date and time when the position of the terminal device Ti was measured. The position information (X, Y) indicates the coordinates of the terminal device Ti on the XY plane. The position information (Z) indicates the floor number (floor number) where the terminal device Ti is present.

  A splash flag is information which shows whether the operation | movement which produces the splash by to-be-tested person Pi was detected. Here, the splash flag “0” indicates that an operation causing the splash by the inspected person Pi was not detected. The splash flag “1” indicates that an operation that causes a splash by the inspected person Pi is detected.

  FIG. 6 is an explanatory diagram illustrating an example of the contents stored in the parameter table 230. In FIG. 6, the parameter table 230 stores parameter information (for example, parameter information 600-1 to 600-24) indicating a spray range and a spray time according to a combination of a disease name, sex, and age.

  Here, the splash range is information for specifying the range affected by the splash scattered by an infected person's cough or sneeze (unit: m). Further, the splash time is information for specifying the period of time affected by the splash scattered by an infected person's cough or sneeze (unit: s). For example, the parameter information 600-1 indicates the splash range “4” and the splash time “15” corresponding to the combination of the disease name “influenza”, the sex “male”, and the age “10”.

  In addition, although the case where each parameter information indicates a spray range and a spray time corresponding to a combination of disease name, sex, and age has been described as an example here, the present invention is not limited thereto. For example, each parameter information may show the splash range and the splash time according to the disease name. Moreover, each parameter information may show the splash range and the splash time according to the combination of sex and sex.

  FIG. 7 is an explanatory diagram showing an example of the stored contents of the infected candidate table 240. In FIG. 7, the infected candidate table 240 includes fields of an infected person ID, a disease name, an infected candidate ID, an infection date and time, an infected place, and a contact count. By setting information in each field, infected candidate information (for example, infected candidate information 700-1 to 700-4) is stored as a record.

  Here, the infected person ID is the user ID of the infected person. The disease name is the disease name of the infected person. The infected candidate ID is the user ID of the infected candidate (inspected person). The date and time of infection is the date and time when a candidate for infection comes into contact with the infected person, that is, the date and time when there is a risk of being infected. The infected place is a place where an infected candidate comes into contact with an infected person, that is, a place where there is a possibility of being infected. The number of times of contact is the number of times that an infected candidate has contacted an infected person.

  For example, in the infected candidate information 700-1, the infected candidate P2 (inspected person P2) is affected by the infected person P1 (inspected person P1), and the infection date “2015” / 12/7 14:00:25 ”indicates that there is a possibility of infection at the infection place“ 5FXX hospital ward ”. Moreover, the number of times of contact “1” when the infected candidate P2 (inspected person P2) contacts the infected person P1 (inspected person P1) is shown.

(Functional configuration example of infected candidate identification apparatus 101)
FIG. 8 is a block diagram illustrating a functional configuration example of the infected candidate identification apparatus 101. In FIG. 8, the infected candidate identification apparatus 101 includes an acquisition unit 801, a detection unit 802, a setting unit 803, a determination unit 804, and an output unit 805. The acquisition unit 801 to the output unit 805 are functions serving as control units. Specifically, for example, by causing the CPU 301 to execute a program stored in a storage device such as the memory 302 and the disk 305 illustrated in FIG. Alternatively, the function is realized by the I / F 303. The processing result of each functional unit is stored in a storage device such as the memory 302 and the disk 305, for example.

  The acquisition unit 801 acquires information on the mover. Here, as described above, the mover information includes, for example, a user ID, position information (t, X, Y, Z), and a splash flag. Specifically, for example, the acquiring unit 801 acquires the moving person information by receiving the moving person information from the terminal device Ti. The acquired traveler information is stored in, for example, the traveler information DB 220 (see, for example, FIG. 5).

  The acquisition unit 801 acquires infected person information. Here, the infected person information includes, for example, a user ID that uniquely identifies the infected person. Further, the infected person information may include information for identifying the attribute of the infected person and the type of illness in which the infected person is affected. The attribute of the infected person is, for example, sex, age, and the like. The information specifying the disease type is, for example, a disease name. Specifically, for example, the acquisition unit 801 acquires infected person information by receiving infected person information from the management apparatus 201.

  The detection unit 802 detects that the infected person has performed an action of causing splashes. Specifically, for example, the detecting unit 802 selects the information on the infected person within a predetermined period T from the moving person information DB 220 in response to the acquired infected person information. Here, the moving person information of the infected person within the predetermined period T is moving person information in which the user ID of the infected person is set and the position information (t) is included within the predetermined period T.

  The predetermined period T can be arbitrarily set. For example, the predetermined period T is set to a period of several days to several months retroactively from the current day. In addition, when the infected person information includes an infection time when the infected person is infected with a pathogen, the detection unit 802 may set the period including the infection time to a predetermined period T. For example, when the infection time is one week ago, the detection unit 802 may set the period from one week ago to the current day as the predetermined period T.

  Next, the detection unit 802 determines whether or not the splash flag of the selected infected person's moving person information is “1”. Here, when the splash flag is “1”, the detection unit 802 detects that the infected person has performed an action of causing the splash. On the other hand, when the splash flag is “0”, the detection unit 802 does not detect that the infected person has performed an action of causing the splash.

  As a result, it is possible to detect that the infected person has performed an action of causing splashes. Note that the selection of the information on the infected person's mover is repeated, for example, until there is no unselected mover information selected from the mover information DB 220. At this time, the detection unit 802 may sequentially select from the moving person information of the infected person whose position information (t) is old.

  For example, it is assumed that the moving person information 500-3 of the infected person P1 (inspected person P1) is selected as a result of the inspected person P1 having the user ID “P1” being designated as an infected person. In this case, the detection unit 802 detects that the infected person P <b> 1 has performed an action of causing the splash because the splash flag of the moving person information 500-3 is “1”.

  The setting unit 803 sets the splash influence range ER of the infected person. Here, the splash influence range ER is a range in which the influence of the splash scattered by coughing or sneezing of the infected person is expected. Specifically, for example, the setting unit 803 refers to the parameter table 230 illustrated in FIG. 6 and specifies the splash range according to the combination of the disease name, sex, and age of the infected person.

  The name, sex and age of the infected person are included in the infected person information, for example. However, the disease name, gender, and age of the infected person may be specified by the infected candidate specifying device 101, for example, from the user ID included in the infected person information.

  Next, the setting unit 803 calculates the splash influence range ER of the infected person based on the specified splash range and the position where the infected person has performed the action of causing the splash. The position where the infected person has caused the action of causing the splash is specified from the position information (X, Y, Z) included in the moving person information of the infected person with the splash flag “1”. Then, the setting unit 803 sets, for example, the calculated splash influence range ER in the infection source information (for example, infection source information 900 shown in FIG. 9 described later) in association with the user ID of the infected person.

  A setting example of the splash influence range ER will be described later with reference to FIG.

  In addition, the setting unit 803 sets the splash influence time ET of the infected person. Here, the splash influence time ET is a period in which the influence of the splash scattered by the coughing or sneezing of the infected person is expected. Specifically, for example, the setting unit 803 refers to the parameter table 230 and identifies the splash time according to the combination of the disease name, sex, and age of the infected person.

  Next, the setting unit 803 calculates the splash influence time ET of the infected person based on the specified splash time and the time when the infected person performs the action of causing the splash. The time when the infected person performed the operation of causing the splash is specified from the position information (t) included in the moving person information of the infected person with the splash flag “1”. Then, the setting unit 803 sets the calculated droplet influence time ET in infection source information (for example, infection source information 900 shown in FIG. 9 described later) in association with the user ID of the infected person.

  Here, a setting example of the splash influence time ET will be described with reference to FIG.

  FIG. 9 is an explanatory diagram showing a specific example of infection source information. In FIG. 9, infection source information 900 is information indicating the splash influence time ET and the splash influence range ER in association with the user ID of the infected person P1.

  Here, the disease name of the infected person P1 is “rubella”, the sex is “male”, and the age is “50 (years)”. In addition, the position where the infected person P1 has performed the operation of causing splashing is defined as a position (2, 2, 5) indicated by the position information (X, Y, Z) of the moving person information 500-3. In addition, the time when the infected person P1 performs the operation of causing the splash is set as the time (2015/12/7 14:00:25) indicated by the position information (t) of the moving person information 500-3.

  In this case, the setting unit 803 refers to the parameter table 230 and specifies the splash range “1 (m)” corresponding to the combination of the disease name “rubella”, the sex “male”, and the age “50” of the infected person P1. . Then, the setting unit 803 calculates the splash influence range ER of the infected person based on the specified splash range “1” and the position (2, 2, 5) where the infected person P1 has caused the splash. .

  In this case, the splash influence range ER is “X−1 ≦ X ≦ X + 1, Y−1 ≦ Y ≦ Y + 1, Z = 5”, that is, “1 ≦ X ≦ 3, 1 ≦ Y ≦ 3, Z = 5”. Become. In addition, although the case where the splash influence range ER is a rectangular shape has been described as an example here, the present invention is not limited thereto. For example, the splash influence range ER may have a circular shape centered on the position where the infected person P1 has performed the action of causing the splash, and the splash range is a radius.

  Further, the setting unit 803 refers to the parameter table 230 and specifies the splash time “10 (s)” corresponding to the combination of the disease name “rubella”, the sex “male”, and the age “50” of the infected person P1. Then, the setting unit 803 determines the splash effect of the infected person P1 based on the identified splash time “10” and the time “2015/12/7 14:00:25” at which the infected person caused the splash. Time ET is calculated.

  In this case, the splash influence time ET is a period from the time “14:00:25” when the infected person P1 performs the action of causing the splash to elapse, that is, “14:00”. : 25 ≦ t ≦ 14: 00: 35 ”. The date (2015/12/7) is omitted.

  Returning to the description of FIG. 8, when it is detected that the infected person has performed an operation of causing splashing, the determining unit 804 refers to the mobile information DB 220 and when the infected person performs the operation, It is determined whether or not the inspected person Pi exists at the place where the person performed the operation.

  Specifically, for example, the determination unit 804 determines that the inspected person Pi falls within a predetermined range (splash effect range ER) including the position where the infected person performs the action at the time when the infected person performs the action of causing the splash. It may be determined whether or not there has been. In addition, the determination unit 804, for example, at the place where the infected person performs the operation Pi during a period until the predetermined time elapses from the time when the infected person performs the operation of generating the splash (splash effect time ET). It may be determined whether or not there has been.

  In addition, the place where the infected person performed the operation of causing the splash is, for example, a hospital room, a diagnosis room, a corridor, a waiting room, an entrance / exit including the position where the infected person performed the operation. Map information for specifying positions such as hospital rooms, examination rooms, hallways, waiting rooms, entrances and the like in the medical institution M is stored in a storage device such as the memory 302 and the disk 305, for example.

  More specifically, for example, the determination unit 804 selects the moving person information of the inspected person Pi within a predetermined period T from the moving person information DB 220. However, the subject Pi is a person different from the infected person. Next, the determination unit 804 refers to the infection source information and identifies the splash influence time ET and the splash influence range ER of the infected person.

  Taking the infection source information 900 (see FIG. 9) as an example, the splash influence time ET “14: 00: 25 ≦ t ≦ 14: 00: 35” and the splash influence range ER “1 ≦ X ≦ 3” of the infected person P1. “1 ≦ Y ≦ 3, Z = 5” is specified.

  Next, the determination unit 804 specifies the position information (t, X, Y, Z) of the inspected person Pi with reference to the moving person information of the selected inspected person Pi. Taking the moving person information 500-9 (see FIG. 5) as an example, the position information (14:00:25, 2, 1, 5) of the subject P2 is specified. The date (2015/12/7) is omitted.

  Then, the determination unit 804 determines whether or not the position (X, Y, Z) indicated by the position information (t, X, Y, Z) of the inspected person Pi is within the splash influence range ER of the infected person. To do. In the example of the subject P2 described above, the determination unit 804 determines that the position (2, 1, 5) of the subject P2 is the splash influence range ER “1 ≦ X ≦ 3, 1 ≦ Y ≦ 3 of the infected subject P1. , Z = 5 ”.

  In addition, the determination unit 804 determines whether or not the time (t) indicated by the position information (t, X, Y, Z) of the inspected person Pi is within the splash influence time ET of the infected person. In the example of the inspected person P2 described above, the determination unit 804 determines that the time (14:00:25) of the inspected person P2 is the splash influence time ET “14: 00: 25 ≦ t ≦ 14: 00 of the infected person P1. : 35 ”.

  Then, the determination unit 804 determines that there is an inspected person Pi when it is within the splash influence range ER of the infected person and within the splash influence time ET of the infected person. Thereby, the person to be inspected Pi can be identified as a candidate who may be infected. In the example of the inspected person P2 described above, the determining unit 804 determines that the inspected person P2 is in the place where the infected person P1 performs the operation when the infecting person P1 performs the operation of causing the splash.

  Note that the selection of the moving person information of the inspected person Pi is repeated, for example, until there is no unselected moving person information not selected from the moving person information DB 220. At this time, the determination unit 804 may sequentially select, for example, the moving person information of the inspected person Pi whose position information (t) is old.

  If it is determined that the subject Pi has been present, for example, the user ID of the subject Pi is stored in the infected candidate table 240 shown in FIG. At this time, the determination unit 804 may record the number of times that the inspected person Pi has been determined in association with the user ID of the inspected person Pi.

  More specifically, the determination unit 804 sets information in each field of the infected candidate table 240 with the user ID of the inspected person Pi as the infected candidate ID. Thereby, the infected candidate information is stored as a new record. However, when the infected candidate information having the same combination of the infected person ID, the disease name, and the infected candidate ID has already been registered, the determination unit 804 increments the contact count.

  In addition, as the infection date and time, for example, the earliest time of the time (t) indicated by the moving person information determined that the inspected person Pi was present, that is, the time when the inspected person Pi contacted the infected person. The oldest time is set. In addition, as the infection location, for example, the name of a location (for example, a ward, a room, a corridor, etc.) including the position (X, Y, Z) indicated by the mobility information determined to have been the subject Pi is set. The

  In the example of the inspected person P2 described above, when the infected person P1 performs the operation of causing the splash, it is determined that the inspected person P2 is present at the place where the infected person P1 has performed the operation. Information 700-1 is stored in the infected candidate table 240 as a new record.

  The output unit 805 outputs the identification information of the inspected person Pi when it is determined that the inspected person Pi exists. The identification information of the inspected person Pi is, for example, the name of the inspected person Pi. The name of the inspected person Pi is stored in a storage device such as the memory 302 and the disk 305 in association with the user ID of the inspected person Pi, for example.

  Further, when it is determined that there is an inspected person Pi, the output unit 805 may output the identification information of the inspected person Pi in association with the identification information of the infected person. The identification information of the infected person is, for example, the name of the infected person. For example, the name of the infected person is stored in a storage device such as the memory 302 or the disk 305 in association with the user ID of the infected person.

  Further, the output unit 805 may output the number of times it is determined that the subject Pi has been present in association with the identification information of the subject Pi and the identification information of the infected person. The number of times that the person to be inspected Pi has been determined corresponds to the number of times the person to be inspected Pi has contacted the infected person.

  Specifically, for example, the output unit 805 may generate screen information of an infected candidate list screen (for example, see FIG. 10 described later) with reference to the infected candidate table 240. The infected candidate list screen is a screen showing a list of inspected persons Pi who may be infected.

  Then, the output unit 805 may transmit the generated screen information of the infected candidate list screen to the management apparatus 201. As a result, the management apparatus 201 can list and present the inspected persons Pi who may be infected. An example of the infected candidate list screen will be described later with reference to FIG.

  Further, the output unit 805 generates a warning message (for example, see FIG. 11 described later) notifying the subject Pi that there is a risk of infection when it is determined that the subject Pi is present. It may be. Then, the output unit 805 may transmit the generated warning message to the terminal device Ti of the inspected person Pi. A specific example of the warning message will be described later with reference to FIG.

  Further, the output unit 805 may output the identification information of the inspected person Pi when the number of times that the inspected person Pi has been determined exceeds a predetermined number (for example, twice). The predetermined number of times can be arbitrarily set, for example, about 2 to 5 times. Thereby, when the strength of the suspicion that the inspected person Pi is infected by the influence of the infected person increases, the identification information of the inspected person Pi can be output.

(Screen example of infected candidate list screen)
Next, a screen example of the infected candidate list screen displayed on the display of the management apparatus 201 (for example, the display 406 shown in FIG. 4) will be described.

  FIG. 10 is an explanatory diagram illustrating a screen example of the infected candidate list screen. In FIG. 10, an infected candidate list screen 1000 is a screen showing a list of inspected persons Pi who may be infected. The infected candidate list screen 1000 is an example of a screen that is displayed when the inspected person P1 is designated as an infected person.

  According to the infected candidate list screen 1000, for each infected candidate who may be infected, it is possible to grasp which illness, when and where there is a suspicion of being infected by which infected person. For example, an administrator (physician or nurse) has received an infection date “2015/12/7 14:14” when the infected candidate “Ichiro Suzuki” is affected by the infected person “Fujitaro” and has the disease name “rubella”. At 00:25 ", it can be grasped that there is a suspicion of being infected at the infection place" 5FXX hospital ward ".

  Further, according to the infected candidate list screen 1000, the degree of suspicion of infection can be determined from the number of times of contact with an infected person. For example, the administrator (doctor or nurse) can determine that the more frequently the contact with the infected person, the stronger the suspicion that the infected candidate is infected due to the influence of the infected person.

(Specific example of warning message)
Next, a specific example of a warning message displayed on the display 405 of the terminal device Ti will be described.

  FIG. 11 is an explanatory diagram illustrating a specific example of a warning message. In FIG. 11, a warning message 1100 is information for notifying the subject P2 (name: Ichiro Suzuki) that there is a risk of infection. According to the warning message 1100, the subject P2 (name: Ichiro Suzuki) can know that there is a suspicion of being infected with “rubella” on December 7, 2015 at 14:00:25.

  In this way, by notifying that there is a risk of infection, it is possible to urge the subject P2 (name: Ichiro Suzuki) to receive a doctor's examination or the like. As a result, it is possible to lead to early detection of infection with “rubella”, and consequently, the severity of symptoms can be prevented.

(Upload processing procedure of terminal device Ti)
Next, an upload processing procedure of the terminal device Ti will be described. The upload process is executed at regular intervals of about several seconds, for example.

  FIG. 12 is a flowchart illustrating an example of an upload processing procedure of the terminal device Ti. In the flowchart of FIG. 12, first, the terminal device Ti obtains position information indicating the position of the own apparatus and the time when the position is measured by measuring the position of the own apparatus (step S1201).

  Next, the terminal device Ti determines whether or not an operation for causing splashing has been detected based on the output values of the various sensors 403 for the latest fixed time (step S1202). Here, when the operation that causes the splash is not detected (step S1202: No), the terminal device Ti sets “0” in the splash flag (step S1203), and proceeds to step S1205.

  On the other hand, when the operation causing the splash is detected (step S1202: Yes), the terminal device Ti sets “1” in the splash flag (step S1204). Next, the terminal device Ti creates moving person information including the acquired position information and the installed splash flag (step S1205).

  Then, the terminal device Ti transmits the created moving person information to the infected candidate specifying apparatus 101 (step S1206), and ends a series of processes according to this flowchart. Accordingly, it is possible to periodically upload the traveler information from the terminal device Ti to the infected candidate specifying device 101.

(Information collection processing procedure of infected candidate identification apparatus 101)
Next, the information collection processing procedure of the infected candidate specifying apparatus 101 will be described.

  FIG. 13 is a flowchart illustrating an example of the information collection processing procedure of the infected candidate identification apparatus 101. In the flowchart of FIG. 13, the infected candidate specifying apparatus 101 determines whether or not the moving person information has been received from the terminal apparatus Ti (step S1301). Here, the infected candidate identification apparatus 101 waits for the reception of the mover information (step S1301: No).

  If the infected candidate specifying apparatus 101 receives the moving person information (step S1301: Yes), the received moving person information is stored in the moving person information DB 220 (step S1302), and a series of processes according to this flowchart is performed. Exit. As a result, it is possible to collect the mobile information that is periodically transmitted from the terminal device Ti.

(Infected candidate identification process procedure of infected candidate identification apparatus 101)
Next, an infected candidate specifying process procedure of the infected candidate specifying apparatus 101 will be described.

  FIG. 14 is a flowchart illustrating an example of the infected candidate identification processing procedure of the infected candidate identification apparatus 101. In the flowchart of FIG. 14, first, the infected candidate identifying apparatus 101 determines whether or not infected person information has been received from the management apparatus 201 (step S1401). Here, the infected candidate identification apparatus 101 waits for reception of infected person information (step S1401: No).

  If the infected candidate specifying apparatus 101 receives the infected person information (step S1401: Yes), the parameter table 230 is referred to, and the infected person's disease name, sex, and age are included in the infected person information. The corresponding splash range and splash time are specified (step S1402).

  Next, the infected candidate identifying apparatus 101 selects the information on the infected person within the predetermined period T from the moving person information DB 220 (step S1403). Then, the infected candidate specifying apparatus 101 determines whether or not the splash flag of the selected moving person information is “1” (step S1404).

  Here, when the splash flag is “0” (step S1404: No), the infected candidate identification apparatus 101 proceeds to step S1409. On the other hand, when the splash flag is “1” (step S1404: Yes), the infected candidate specifying apparatus 101 performs an operation in which the infected person specified from the specified splash range and the selected moving person information causes a splash. Based on the determined position, the splash influence range of the infected person is calculated (step S1405).

  Next, the infected candidate specifying apparatus 101 calculates the splash influence time of the infected person based on the specified splash time and the time at which the infected person specified from the selected moving person information generates the splash. Calculate (step S1406). The infected candidate identifying apparatus 101 sets the calculated splash influence range and the splash influence time in the infection source information (step S1407).

  Next, the infected candidate identifying apparatus 101 executes a collation process of the selected mover information (step S1408). A specific processing procedure of the collation processing will be described later with reference to FIG. Then, the infected candidate specifying apparatus 101 determines whether or not there is unselected non-selected moving person information within a predetermined period T that is not selected from the moving person information DB 220 (step S1409).

  If there is unselected mover information (step S1409: YES), the infected candidate specifying apparatus 101 returns to step S1403. On the other hand, when there is no unselected mover information (step S1409: No), the infected candidate specifying apparatus 101 refers to the infected candidate table 240 and generates screen information of the infected candidate list screen. (Step S1410).

  Then, the infected candidate specifying apparatus 101 displays the generated screen information of the infected candidate list screen on the management apparatus 201 (step S1411), and ends the series of processes according to this flowchart. Thereby, it is possible to present a list of inspected persons Pi who may be infected due to the influence of the infected person specified from the infected person information.

  Next, a specific processing procedure of the collation processing in step S1408 shown in FIG. 14 will be described with reference to FIG.

  FIG. 15 is a flowchart illustrating an example of a specific processing procedure of the matching process. In the flowchart of FIG. 15, first, the infected candidate identifying apparatus 101 selects the moving person information of the inspected person Pi within the predetermined period T from the moving person information DB 220 (step S1501). However, the subject Pi is a person different from the infected person.

  Next, the infected candidate specifying apparatus 101 refers to the infection source information and determines whether or not the position of the inspected person Pi specified from the moving person information of the selected inspected person Pi is within the splash influence range. Is determined (step S1502). Here, when it is outside the splash influence range (step S1502: No), the infected candidate identifying apparatus 101 proceeds to step S1506.

  On the other hand, if it is within the splash influence range (step S1502: Yes), the to-be-infected candidate specifying apparatus 101 refers to the infectious source information and is to be inspected from the moving person information of the selected inspected person Pi. It is determined whether or not the time when the position of Pi is measured is within the splash influence time (step S1503).

  Here, when it is outside the splash influence time (step S1503: No), the infected candidate identifying apparatus 101 proceeds to step S1506. On the other hand, when it is within the splash influence time (step S1503: Yes), the infected candidate identification device 101 identifies the inspected person Pi as an infected candidate (step S1504).

  Then, the infected candidate specifying apparatus 101 updates the stored contents of the infected candidate table 240 (step S1505). Next, the infected candidate identification apparatus 101 determines whether there is the moving person information of the inspected person Pi within the predetermined period T that has not been selected from the moving person information DB 220 (step S1506).

  Here, when there is unselected moving person information (step S1506: Yes), the infected candidate specifying apparatus 101 returns to step S1501. On the other hand, if there is no unselected mover information (step S1506: No), the infected candidate specifying apparatus 101 returns to the step that called the verification process.

  Thereby, when an infected person performs the operation | movement which produces a splash, the to-be-tested person Pi who existed in the place can be specified as an infected candidate with a possibility of infection.

  As described above, according to the infected candidate identifying apparatus 101 according to the embodiment, when it is detected that the infected person has performed an operation of causing splashes, the infected person DB 220 is referred to and the infected person is referred to. When the person performs the operation, it can be determined whether or not the inspected person Pi exists at the place where the infected person performs the operation. And according to the to-be-infected candidate specifying device 101, when it is determined that the inspected person Pi exists, the identification information of the inspected person Pi can be output. As a result, when the infected person coughs or sneezes, the inspected person who is in the same place as the infected person can be narrowed down as candidates who may be infected.

  Further, according to the infected candidate identification apparatus 101, the infected person is inspected at the place where the infected person performs the operation within the splash influence time ET until the predetermined time elapses from the time when the infected person performs the action of generating the splash. It can be determined whether or not there is a person Pi. Thereby, the test subject who was in the same place as the infected person can be narrowed down as a candidate with the possibility of infection within the period when the influence of the splash scattered by the infected person's cough or sneeze is expected.

  Further, according to the infected candidate specifying apparatus 101, the splash influence time ET can be set according to the attribute of the infected person and / or the type of illness in which the infected person is affected. Thereby, in consideration of different vital capacity depending on attributes such as the sex and age of the infected person, it is possible to set a period of time affected by the splashes of the infected person due to coughing and sneezing. In addition, in consideration of different infectivity depending on the type of illness in which the infected person is affected, it is possible to set a period in which the affected person is affected by the splashes of the infected person due to coughing or sneezing.

  Also, according to the infected candidate identifying apparatus 101, whether or not the subject Pi is within the splash-affected range ER including the position where the infected person performed the action at the time when the infected person performed the action of causing the splash. Can be determined. As a result, when an infected person coughs or sneezes, it is possible to narrow down subjects to be inspected who are within a range where the influence of splashes scattered by the infected person's cough or sneezing is expected to be a candidate for infection. .

  Further, according to the infected candidate identifying apparatus 101, the splash influence range ER can be set according to the attribute of the infected person and / or the type of illness to which the infected person is affected. This makes it possible to set a range that is affected by splashes caused by coughing or sneezing of an infected person in consideration of different vital capacity depending on attributes such as sex and age of the infected person. In addition, in consideration of different infectivity depending on the type of disease affected by the infected person, it is possible to set a range that is affected by the splashes of the infected person due to coughing or sneezing.

  Further, according to the infected candidate specifying apparatus 101, it is possible to determine whether or not the inspected person Pi is within the splash influence range ER within the splash influence time ET. As a result, within a period in which the influence of the splash splashed by the infected person's cough or sneeze is expected, the subject to be inspected within the range in which the influence of the splash is expected can be narrowed down as a candidate who may be infected .

  Further, according to the infected candidate specifying apparatus 101, when it is determined that there is an inspected person Pi, the identification information of the inspected person Pi can be output in association with the identification information of the infected person. As a result, it becomes possible to know which infected person is suspected of being infected by a candidate who may be infected.

  In addition, according to the infected candidate identifying apparatus 101, the number of times (the number of times of contact) determined that the inspected person Pi has been recorded is recorded, and the recorded number of times is determined from the identification information of the inspected person Pi and the identification information of the infected person Corresponding output is possible. Thereby, it is possible to determine the degree of suspicion that the subject Pi has been infected due to the influence of the infected person.

  In addition, according to the infected candidate specifying apparatus 101, when the number of times it is determined that there is a subject Pi exceeds a predetermined number, identification information of the subject Pi can be output. Thereby, when the degree of the suspicion that the subject Pi has been infected by the influence of the infected person increases, the identification information of the subject Pi can be output.

  Therefore, according to the infected candidate identification apparatus 101, it is possible to narrow down candidates who are likely to be infected, and the spread of nosocomial infection in the medical institution M can be suppressed. Moreover, since it is possible to identify a candidate who may be infected retroactively for a predetermined period of time when a subject is found to be infected with a pathogen, a new infected person can be identified at an early stage. Can be prevented.

  The infected candidate identification method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. The infected candidate identification program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The infected candidate identification program may be distributed via a network such as the Internet.
