By the way, hospital rooms are usually equipped with lighting fixtures and a large number of medical devices. Light is emitted from the lighting equipment, and monitor sounds and alarm sounds are emitted from the medical equipment. Further, in the hospital room, medical staff interviews, talks, and the like are exchanged. It is difficult to eliminate such irradiation light from lighting equipment, reproduction of monitor sounds and alarm sounds, interviews, etc. from the hospital room because they are necessary for treatment. However, from the standpoint of individual patients, there is an appropriate volume and amount of light for each patient. In particular, for low birth weight infants with immature physical functions, it is believed that preparing an environment close to that of the mother's womb promotes their growth.

Therefore, the determination device can allow the user or the like to recognize the result determined by the determination unit at a glance. In addition, even if the user or the like takes other measures and cannot take his/her eyes off the screen, the result of determination by the determination unit can be recognized by sound. Further, the determination device can make the result of determination by the determination unit recognizable by lighting or blinking of light even when the user or the like is away from the determination device.

(5) In the determination device according to any one of (1) to (4) above, the amount of light indicated by the measurement signal is reduced by blocking the light irradiated onto the bed based on the determination result of the determination unit. further includes a light amount adjusting unit that adjusts the In this case, if the determining unit determines that the amount of light is not appropriate, the determination device of one embodiment of the present invention can adjust the inappropriate amount of light by blocking the light.

(First embodiment)
A determination device 3 according to a first embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram showing an example of a determination system 1 including a determination device 3. As shown in FIG. The determination system 1 includes, for example, a sensor section 2, a determination device 3, an external input device 4, an incubator 5, and a medical device 6. The example of FIG. 1 shows an example in which the determination device 3 is a medical column (a stationary device that aggregates medical devices). The example of FIG. 1 shows an example in which the medical devices 6 are collectively installed on the pillar portion where the determination device 3 is installed. The determination device 3 includes an acquisition section 30 and a display section 35 .

The sensor unit 2 is installed inside the nursery container 51 of the incubator 5, measures the amount of light inside the nursery container 51 and the sound volume, and outputs the measured light amount and the like to the determination device 3 as a measurement signal. The sensor unit 2 may be placed on the upper surface of the bed of the nursing container 51, fixed to the inner side surface of the nursing container 51, or attached to a newborn baby housed in the nursing container 51. . When the sensor unit 2 is fixed to the inner side surface of the nursery container 51, it may be provided with a fixture for fixing to the inner side surface of the nursery container 51, or the sensor unit 2 may be attached to the nursery container 51. Fixtures may be provided for securing.

The determination device 3 acquires the measurement signal from the sensor unit 2 through the cable L with the acquisition unit 30 . Based on the measurement signal from the sensor unit 2, the determination device 3 determines whether or not the amount of light and the sound volume inside the nursery container 51 are appropriate. Appropriate light intensity and sound volume means, for example, that the measured light intensity and sound volume do not exceed predetermined allowable recommended values. Also, the measured amount of light and volume must be within a predetermined range including the recommended permissible values. Further, the determination device 3 changes or sets a threshold used for determination based on an operation signal input from the external input device 4 . Accordingly, the determination device 3 compares the measurement signal from the sensor unit 2 with the threshold used for determination, and determines whether or not the amount of light and sound volume inside the nursery container 51 are appropriate. The determination device 3 causes the display unit 35 to display the determination result. In the determination device 3 , the display unit 35 may be installed at a position or in an orientation that makes it difficult for the light emitted from the display unit 35 to irradiate the interior of the nursery container 51 .

The external input device 4 is, for example, an input device for externally setting a threshold value by a user. The external input device 4 is, for example, an up key, a down key, a numeric keypad, or the like. By operating the external input device 4 , the user inputs thresholds, numerical values, patient identification numbers, and the like used for determination to the determination device 3 . Also, the external input device 4 may be a keyboard, a volume controller, a slide switch, or the like.

The incubator 5 includes, for example, an incubator container 51 , an incubator environment controller 52 , and casters 53 . Nursing container 51 is, for example, a container in which a newborn baby recognized as needing treatment is accommodated. The incubator environment controller 52 controls the temperature, humidity, oxygen concentration, and the like in the space inside the incubator container 51 . A care window 510 is provided on the longitudinal side surface of the nursery container 51 so that a medical worker or the like puts his or her hand inside the nursery container 51 to perform treatment or the like. Further, a cover 511 is hung on the nursery container 51 . By covering the nursery container 51 with the cover 511 , it is possible to block or reduce the light of the illumination that illuminates the nursery container 51 .

The medical equipment 6 is equipment necessary for treatment, such as a treatment lamp 61 and a monitor 62 . A treatment lamp 61 is a lighting fixture that brightly illuminates an affected area or the like during treatment. The monitor 62 is, for example, a monitoring device that displays biological information of the newborn baby housed in the nursery container 51 and informs of an abnormality. These medical devices 6 are devised, for example, so as not to irradiate the inside of the nursery container 51 with light and not to transmit unnecessary sounds. For example, the treatment lamp 61 has an arm portion 63 so as to accurately illuminate a portion necessary for treatment without illuminating the entire room during treatment. Also, the monitor 62 is installed in an orientation in which the light for displaying the monitor content is less likely to irradiate the inside of the nursery container 51 . In addition, the monitor 62 is installed in a position and in an orientation in which the alarm sound that informs an abnormality is difficult to be transmitted to the inside of the nursery container 51 .

Newborns born earlier than expected due to reasons such as premature birth do not have sufficient tolerance to external stimuli due to their immature bodily functions. For this reason, it is necessary to grow them in an environment close to the mother's womb with reduced external stimuli. The NICU environment recommended by the American Academy of Pediatrics (hereinafter referred to as the recommended environment) has a light intensity range of 100 to 200 [lx] during the day (Neonatal Care 2016 vol.29 no.11 (1063)), and volume It is also said that the upper limit is 45 [dB] (same (1057)). This is, for example, an environment comparable to the amount of light from a street lamp at night and the sound volume of a library. At the site of treatment, it is necessary to visually confirm the progress of the infusion and the numerical value of the drug, so lighting that can read the scale of the infusion and the numerical value of the drug is necessary. . In addition, at the site of treatment, the patient's name is read aloud to confirm the patient's name to prevent the wrong drug from being administered to the wrong patient. Sometimes it's hard to say. In other words, it is difficult to achieve the same level of recommended environment for the entire hospital room as the amount of light from streetlights and the volume of sound in the library.

In addition, the sensor sounds from the medical devices 6 placed around the incubator 5 and the conversations of medical personnel near the incubator 5 are somewhat loud outside the incubator container 51, but they It is unclear how it is transmitted inside 51. Furthermore, the sound of opening and closing the care window 510 of the nursery container 51 may be transmitted in a large volume inside the nursery container 51 although the sound is small outside the nursery container 51 . How loud the opening and closing sound of the maintenance window 510 is actually inside the nursery container 51 is unknown unless it is actually measured. The determination device 3 of the present embodiment can display whether or not the amount of light and sound volume inside the nursery container 51 are appropriate in such a medical field, and inform the medical staff. As a result, if the amount of light is not appropriate, the medical staff can reduce the amount of light irradiated to the nursery container 51 by changing the direction of the illumination, changing the brightness of the illumination, or putting the cover 511 on. can be done. In addition, if the volume is not appropriate, the medical staff can try to reduce the noise inside the nursery container 51 by, for example, talking away from the infant nursery 5 . As described above, by using the determination device 3 of the embodiment, it is possible to quickly take countermeasures when the amount of light and the sound volume are not appropriate.

Although FIG. 1 shows an example in which the determination device 3 is used for a nursery container 51 whose periphery and upper portion are surrounded by a transparent resin material or the like, the present invention is not limited to this. The determination device 3 is used in a cot (a bed for a newborn whose upper part is not covered with a synthetic resin or the like but whose bed is surrounded) used in a growing care unit (GCU) or the like. It may also be used in pediatric beds and adult beds. In the following description, the nursery container 51, the cot, the child's bed, and the adult's bed are collectively referred to simply as beds.

The sensor unit 2 obtains environmental information regarding the environment including at least one of the amount of light above the bed and the sound volume. The environmental information may include only the amount of light, may include only the volume, or may include both the amount of light and the volume. The amount of light and volume on the bed are, for example, the amount of light and volume in the space where the patient lies on the bed (hereinafter referred to as measurement space). The measurement space is, for example, a space surrounded by four planes substantially parallel to a vertical plane surrounding the upper surface of the bed and a ceiling plane. When the judging device 3 is used in a nursery container 51 whose top is covered as shown in FIG. Moreover, when the determination device 3 is used for a bed, the ceiling surface is the ceiling surface of the room in which the bed is placed. In addition, when a cover such as a canopy is placed between the bed and the ceiling surface, the ceiling surface is the cover such as the canopy. In other words, the measurement space is a space surrounded by the top surface of the bed, a plane that surrounds the bed and is parallel to the substantially vertical plane, and the ceiling surface that is first arranged in the vertical direction from the top surface of the bed. When there is no physical ceiling surface such as outdoors, for example, a plane parallel to a horizontal surface at a height similar to that of a standard indoor ceiling surface where the determination device 3 is installed is used as a virtual ceiling surface. . The measurement space also includes a space outside the measurement space if the space is expected to have the same amount of light or volume as the measurement space.

The sensor unit 2 may measure the amount of light and volume at any location within the measurement space. For example, since the amount of light in the space around the patient's eye position can be said to be close to the amount of light felt by the patient, the sensor unit 2 may measure the amount of light on the patient's head side. Alternatively, when it is not possible to assume where the patient's head side will be in the measurement space, the sensor unit 2 may measure the amount of light at the center of the measurement space. As for the sound volume, the sensor unit 2 may measure the sound volume at the patient's head side, or may measure the sound volume at the center of the measurement space. The sensor unit 2 may measure the amount of light and the volume at the same place in the measurement space, or may measure the volume at a place different from the place where the amount of light is measured.
Moreover, in the example of FIG. 1, the sensor unit 2 outputs the measurement signal to the determination device 3 via the cable L, but the present invention is not limited to this. The sensor unit 2 may transmit the measurement signal using a short-range wireless communication method such as infrared rays or Bluetooth (registered trademark). The cable L can be eliminated by the sensor unit 2 transmitting the measurement signal by wireless communication. Moreover, the sensor unit 2 may transmit the measurement signal to the determination device 3 via the network.

FIG. 2 is a configuration diagram showing the configurations of the sensor section 2 and the determination device 3. As shown in FIG. The sensor section 2 includes a light quantity sensor 20 and a sound volume sensor 22 . The determination device 3 includes an acquisition unit 30, an input unit 31, a storage unit 33, an audio output unit 34, a display unit 35, and a control unit 36 (an example of a determination unit). The audio output unit 34 and the display unit 35 are examples of the output unit. These components in the determination device 3 are connected via a bus B so as to be able to communicate with each other.

The light amount sensor 20 measures the amount of light. The light intensity sensor 20 has, for example, a light receiving portion that acquires light rays emitted from the sun, lighting equipment, or the like, and measures the amount of light by outputting a signal corresponding to the amount of light received by the light receiving portion. In the present embodiment, the light quantity sensor 20 measures the light quantity of visible light as light that the human body responds to (for example, stimulating awakening), but is not limited to this. The amount of light measured by the light amount sensor 20 may be the amount of ultraviolet light, the amount of infrared light, or the amount of light in another band. The light amount sensor 20 may measure the amount of light in a band that includes visible light and that is wider than visible light, from ultraviolet rays to infrared rays. The light intensity sensor 20 outputs a measurement signal indicating the measured light intensity to the determination device 3 .

Volume sensor 22 measures the volume. The sound volume sensor 22 has, for example, a microphone unit that acquires sensor sounds and alarm sounds output from medical equipment, voices of medical personnel, etc., and outputs a signal corresponding to the volume of sound input to the microphone unit. The volume is measured by The volume sensor 22 is, for example, a sound level meter. The volume sensor 22 measures the amount of signal in an audible band (for example, a band from 20 [Hz (Hertz)] to 20 [kHz]), but is not limited to this, and may be one of the audible bands. It may measure the band of the part, or it may measure the signal amount of a band that includes the audible band and is wider than the audible band. The volume sensor 22 outputs a measurement signal indicating the measured volume to the determination device 3 .

The acquisition unit 30 acquires measurement signals from the sensor unit 2 . The measurement signal from the sensor unit 2 may be an analog signal representing the amount of light, or may be a digital signal obtained by converting the analog signal into a digital signal. When the measurement signal from the sensor section 2 is an analog signal, the acquisition section 30 holds the analog signal at a predetermined sampling rate and converts the held analog signal amount into a digital value. Acquisition unit 30 outputs a digital signal based on the measurement signal from sensor unit 2 to control unit 36 .

The input unit 31 outputs an externally input operation signal to the control unit 36 . The operation signal includes a signal for identifying a patient, a signal representing a light intensity threshold, and a signal representing a volume threshold. In the following description, a case will be described in which the operation signal includes a signal representing the threshold value of the amount of light. The case where the operation signal includes the signal indicating the volume threshold is the same as the case where the signal indicating the amount of light is included, so the description thereof will be omitted.

The operation signal is, for example, a signal indicating which threshold level is to be set among the threshold levels divided into a plurality of stages. Specifically, the input unit 31 acquires an operation signal based on the content input by the user to the external input device 4 (for example, up key and down key). For example, when the up key is pressed once, the input unit 31 acquires an operation signal indicating that the light amount threshold level is to be increased by one level. Further, when the down key is pressed once, the input unit 31 acquires an operation signal indicating that the light amount threshold level is lowered by one level. The input unit 31 outputs the acquired operation signal to the control unit 36 .

The storage unit 33 is realized by, for example, a HDD (Hard Disc Drive), flash memory, EEPROM (Electrically Erasable Programmable Read Only Memory), or RAM (Random Access Memory). The storage unit 33 stores programs to be executed by the control unit 36 .
The storage unit 33 stores criteria for judging the environment according to the user of the bed. Specifically, the storage unit 33 stores a threshold level database 330 , a light amount level correspondence database 331 , and a volume level correspondence database 332 as variables used in the determination processing performed by the determination device 3 . The threshold level database 330 stores the threshold levels of the amount of light and the volume when the determination device 3 determines whether the amount of light and the volume are appropriate. The light amount level correspondence database 331 stores light amount levels and light amount thresholds corresponding to the light amount levels. The volume level correspondence database 332 stores volume levels and volume thresholds corresponding to the volume levels.

The storage unit 33 stores biological information such as heart rate, blood pressure, and body temperature of the patient. For example, a medical worker measures a patient's heart rate, blood pressure, body temperature, and the like using a heart rate monitor, a blood pressure monitor, a thermometer, and the like. Then, the medical staff inputs biometric information to the external input device 4 . The external input device 4 outputs the biological information input by the medical staff to the determination device 3 . Then, the determination device 3 stores the biological information from the external input device 4 in the storage section 33 via the control section 36 . Alternatively, a biological information sensor such as a heartbeat monitor attached to the patient outputs biological information such as the measured heart rate to the acquisition unit 30 . The acquisition unit 30 then outputs the biological information from the biological information sensor to the control unit 36 , and the control unit 36 stores the biological information in the storage unit 33 .

FIG. 3 is a diagram showing the data configuration of the storage unit 33 used in the determination device 3 of the first embodiment. FIG. 3A shows the data structure of the threshold level database 330. FIG. FIG. 3B shows the data configuration of the light amount level correspondence database 331. As shown in FIG. FIG. 3(c) shows the data configuration of the volume level correspondence database 332. As shown in FIG.

As shown in FIG. 3A, the threshold level database 330 stores patient IDs, light amount level information, and volume level information. A patient ID is information that identifies a patient (for example, a patient identification number). The light amount level information is information indicating which level among a plurality of light amount levels. The volume level information is information indicating which level among a plurality of volume levels. The example of FIG. 3A shows an example in which "2" is stored in the light intensity level information and "3" is stored in the sound volume level information.
A patient ID is included in the threshold level database 330, and the light amount level information and the volume level information are stored in association with the patient ID, so that the light amount level and the volume level corresponding to each individual patient can be stored. . Thereby, the determination device 3 can determine whether or not the amount of light and the sound volume are appropriate. The patient ID may be information for identifying the bed (for example, bed ID), or may be information for identifying the user who uses the bed although he is not the patient (for example, user ID). In this way, light amount level information, sound volume level information, and the like are stored in association with each other as a judgment criterion according to the patient ID and the environment (light amount or sound volume) that is preferable for the patient indicated by the patient ID. It is possible to output the result of determination so as to create an environment suitable for the user (patient).

The light amount level correspondence database 331 stores light amount level information and threshold information. The light intensity level information is information corresponding to the light intensity level information in the threshold level database 330 . The threshold information is information indicating the upper limit of the allowable amount of light.
In the example of FIG. 3B, the light amount level 1 stores the upper limit of the light amount that does not interfere with sleep. Specifically, 30 [lx] is stored in the threshold information. Further, the light amount level 2 stores a recommended light amount range during the daytime. Specifically, 200 [lx] is stored in the threshold information.
By storing the light amount level and the threshold value in the light amount level correspondence database 331 in association with each other, the determination device 3 refers to the light amount level correspondence database 331 and uses the threshold value according to the set level to determine the light amount sensor 20. can determine whether the detected amount of light is appropriate.
The threshold may be set for each time period (for example, set separately for nighttime and daytime). For example, the daytime threshold value corresponding to light amount level 2 may be set to 200 [lx], and the nighttime threshold value may be set to 30 [lx]. In this case, for example, the determination device 3 refers to the light intensity level correspondence database 331 according to time information indicated by a timer (not shown) provided therein, and uses a threshold corresponding to the set level. Also, the threshold value may indicate the absolute value of the amount of light or sound volume at that moment, or may indicate the amount of relative change. When the threshold value indicates the amount of change, for example, the determination device 3 determines that the light amount is not appropriate when it suddenly becomes bright even if the light amount is small.
Also, the threshold may be a threshold that indicates the lower limit of the allowable amount of light or volume. In this case, the determination device 3 determines that the light amount is not appropriate when the light amount measurement value is below the lower limit threshold. Further, the determination device 3 uses both the upper threshold and the lower threshold, and determines that the light intensity is appropriate when the light intensity measurement value falls within the range from the lower threshold to the upper threshold. can be An environment with no light or sound does not necessarily have a positive effect on brain development. Hearing a parent's conversation or lullaby for a newborn can also stabilize the condition of the newborn. In such a case, it may be determined to be appropriate when the lower limit threshold is not exceeded, or when the measured value falls between the lower limit threshold and the upper limit threshold.
Also, the threshold may be set for each range of frequencies and the like measured by the sensor 2 . For example, the light amount sensor 20 measures the light amount for each frequency range indicated by each of ultraviolet light, visible light, and infrared light, and the light amount level correspondence database 331 stores an ultraviolet amount threshold, a visible light amount threshold, and an infrared amount threshold, respectively. set. In this case, for example, the determination device 3 refers to the light amount level correspondence database 331 according to the type of light measured by the light amount sensor 20 (type of ultraviolet light, visible light, or infrared light), Use a threshold.

Volume level information and threshold information are stored in the volume level correspondence database 332 . The volume level information is information corresponding to the volume level information of the threshold level database 330 . The threshold information is information indicating the upper limit threshold of volume.
In the example of FIG. 3(c), volume level 1 stores the upper limit value of volume that is preferable for sleep. Specifically, 35 [dB] is stored in the threshold information. Volume level 2 stores, for example, the upper limit value of volume recommended in the NICU. Specifically, 45 [dB] is stored in the threshold information. Volume level 3 stores, for example, an upper limit value of volume that is not preferable as volume measured over a long period of time. Specifically, 65 [dB] is stored in the threshold information.
A threshold value may be set for each range of frequency or the like measured by the sensor 2 . For example, the volume sensor 20 is less than the audible band (for example, less than 20 [Hz]), the audible band (for example, 20 [Hz] or more and less than 20 [kHz]), and the audible band or more (for example, 20 [kHz] or more ), and the volume level correspondence database 332 is set with a lower than audible band threshold, an audible band threshold, and an above audible band threshold, respectively. In this case, the determination device 3 refers to the volume level correspondence database 332 according to, for example, the type of sound measured by the volume sensor 22 (below the audible band, the audible band, or the audible band or higher), Use a threshold according to the type.
By storing the sound volume level and the sound volume threshold in the light amount level correspondence database 331 in association with each other, the determination device 3 refers to the sound volume level correspondence database 332 and uses the threshold corresponding to the set level to determine the sound volume. It can be determined whether the volume detected by the sensor 22 is appropriate.

Returning to FIG. 2, the audio output unit 34 uses sound to output the determination result determined by the control unit 36 by voice, alarm sound, or the like.
When the sound output unit 34 is installed in the housing of the determination device 3 and outputs sound on the incubator 5 side, the sound from the sound output unit 34 is not transmitted as noise to the nursery container 51. For example, it is preferable to set the output direction of the sound in a direction different from the direction of the nursery container 51 or to cover the nursery container 51 with a cover 511 . Also, the audio output unit 34 may output a lullaby or the like. It is conceivable that the condition may be stabilized by playing a lullaby to the newborn. The audio output unit 34 also has a volume adjustment unit that adjusts the volume of the output sound. The volume control section includes, for example, a volume control knob and a mute button, allowing the user to increase or decrease the volume of the sound from the audio output section 34 or mute the sound. As a result, even if there is a possibility that the sound from the audio output unit 34 is transmitted into the childcare container 51, the volume in the childcare container 51 can be prevented from increasing.

The display unit 35 displays the result of determination made by the determination device 3 as to whether or not the amount of light and the sound volume are appropriate. For example, in the example of FIG. 1, the display unit 35 displays the determination result for the volume in the upper part of the display area, a pictogram (speaker figure), and the volume value (“65 dB” numerical value and characters). In addition, the display unit 35 displays the result of light intensity determination, a pictogram (sun figure), and a light intensity value (“100 lx” numerical value and characters) on the lower side of the display area. The display unit 35 may display the determination result in color. For example, the display unit 35 displays in red, which indicates a warning, when the amount of light or the sound volume exceeds the respective set thresholds. In addition, the display unit 35 displays in yellow to draw attention when the amount of light or the volume is within a predetermined range from the threshold set for each (for example, within 5 [dB] for the volume). do. In addition, the display unit 35 displays in green, which indicates peace of mind, when the amount of light or the sound volume falls below a predetermined range from a threshold set for each. Further, the display unit 35 may display the pictogram or the like not only by lighting but also by blinking. Thus, the display unit 35 displays the determination result using at least one or more of numerical values, characters, graphics, and colors. Note that the determination result includes at least the determination result of whether or not it is appropriate, and may further include the measured values of the light amount and the sound volume.

An output unit may be provided in addition to the audio output unit 34 and the display unit 35 described above. Specifically, the output unit may be, for example, a light, a printer, or the like. For example, a plurality of LED lamps of different colors may be provided, and the determination result may be output by lighting or blinking of LED lamps for each color, or the determination result may be printed.
The output unit may be a stationary device or a portable terminal device carried by medical staff. When the output device is a terminal device, the determination result is displayed on the display screen of the terminal device, or an alarm sound or vibration is output according to the determination result.

The control unit 36 controls the acquisition unit 30 , the input unit 31 , the storage unit 33 , the audio output unit 34 and the display unit 35 . The control unit 36 is, for example, a microcontroller equipped with a processor such as a CPU (Central Processing Unit), and is implemented by executing a program stored in a program memory. Also, part or all of the functions executed by these programs may be realized by hardware such as an analog control circuit or FPGA (Field Scale Integration).

Based on the measurement signal acquired by the acquisition unit 30, the control unit 36 determines whether the environment is appropriate. Specifically, based on the measurement signal from the acquisition unit 30, the control unit 36 determines whether or not the amount of light and the sound volume are appropriate. In the following description, processing for determining whether or not the amount of light is appropriate by the control unit 36 will be described. The processing by which the control unit 36 determines whether or not the sound volume is appropriate is the same as the processing for determining the amount of light, so the description thereof will be omitted.

The control unit 36 causes the storage unit 33 to store the operation signal from the input unit 31 . The control unit 36 causes the threshold level database 330 to store the information identifying the patient and the information indicating the light amount level and the sound volume level among the operation signals. Specifically, information identifying the patient is stored in the patient ID, the light amount level is stored in the light amount level information, and the volume level is stored in the volume level information.

The controller 36 acquires the threshold corresponding to the light amount level set for each individual patient. Specifically, the control unit 36 refers to the threshold level database 330 and acquires light amount level information. Then, the control unit 36 refers to the light intensity level correspondence database 331 and acquires a threshold corresponding to the acquired light intensity level information. More specifically, in the example of FIG. 3, the control unit 36 acquires the light intensity level of the threshold level database 330, and sets the threshold "200 [lx]" of the light intensity level correspondence database 331 corresponding to the acquired light intensity level "2". ” is obtained.
The control unit 36 acquires light amount level information, for example, periodically or for each determination. Alternatively, the control unit 36 may acquire the updated light amount level information when the light amount level information is updated. The process by which the control unit 36 updates the light amount level information will be described later in detail.

The control unit 36 determines whether the light amount is appropriate based on the threshold value acquired from the storage unit 33 and the measured light amount value (hereinafter referred to as the light amount measurement value) included in the measurement signal from the acquisition unit 30. judge. Specifically, the control unit 36 compares the threshold value with the light amount measurement value, and determines that the light amount is not appropriate when the light amount measurement value exceeds the threshold value.

Here, the control unit 36 may determine whether or not it is appropriate, or may determine the degree of appropriateness in a plurality of stages. The case of judging the degree of appropriateness in a plurality of stages is, for example, the case of judging the degree of appropriateness in three stages, that is, inappropriate in the warning stage, inappropriate in the caution stage, and appropriate. Specifically, the controller 36 compares the threshold value with the light amount measurement value, and determines that the light amount is not appropriate for the warning stage when the light amount measurement value exceeds the threshold value (200 lux). In addition, when the light amount measurement value is between the threshold value (200 lux) and the light amount value (170 lux) that is less than the threshold value by a predetermined value (for example, 30 lux), the light amount It is determined that it is not appropriate at the stage. Further, the control unit 36 determines that the light amount is appropriate when the light amount measurement value is less than the value (170 lux) obtained by subtracting a predetermined value from the threshold value.

In addition, the control unit 36 outputs the determined determination result to the output unit such as the audio output unit 34 and the display unit 35 . The determination result may include information indicating whether or not the amount of light is appropriate, information indicating the degree of appropriateness (for example, whether it is a warning stage or a caution stage), and information indicating a light amount measurement value.

Here, the control unit 36 may output the determined determination result to a remote output unit via a transmitting unit (not shown). The transmission unit transmits the determination result to the output unit, for example, via a wire, radio, or network. The output unit is arranged, for example, in a nurse station away from the hospital room where the infant incubator 5 is arranged, and outputs according to the determination result.

Also, the control unit 36 updates the threshold level database 330 based on the operation signal from the input unit 31 . The operation signal includes identification information indicating the threshold level of the amount of light or volume, and threshold level information indicating the threshold level. Specifically, when the operation signal includes information for setting the light amount threshold level to "1", the control unit 36 writes "1" to the light amount level information in the threshold level database 330. Memorize. Further, when the operation signal includes information for setting the volume threshold level to "2", the control unit 36 writes "2" to the volume level information of the threshold level database 330 and stores it.

Here, the flow of determination processing performed by the determination device 3 will be described. FIG. 4 is a flow chart showing the flow of determination processing performed by the determination device 3 .
First, as a premise, it is assumed that threshold levels of light amount and sound volume are stored in the determination device 3 based on the operation signal input from the external input device 4 . Then, it is assumed that the determination device 3 refers to the storage unit 33 and obtains thresholds for the amount of light and the volume corresponding to the threshold level. In other words, the determination device 3 preliminarily acquires thresholds for the amount of light and the volume.
The determination device 3 acquires a measurement signal from the sensor section 2 (step S1). The determination device 3 compares the light amount measurement value of the measurement signal with the threshold value of the light amount level, and determines whether or not the light amount level exceeds the threshold value (step S2). If the light amount level exceeds the threshold (step S2, YES), the determination device 3 determines that the light amount is not appropriate (step S3). On the other hand, when the light amount level does not exceed the threshold (step S2, NO), the determination device 3 determines that the light amount is appropriate (step S4).
Further, the determination device 3 compares the volume measurement value of the measurement signal with the volume level threshold, and determines whether or not the volume level exceeds the threshold (step S5). If the volume level exceeds the threshold (step S5, YES), the determination device 3 determines that the volume is not appropriate (step S6). On the other hand, when the volume level does not exceed the threshold (step S5, NO), the determination device 3 determines that the volume is appropriate (step S7). Then, the determination processing shown in this flowchart ends. In this flowchart, the process of determining the volume is performed after the process of determining the amount of light, but the process of determining the amount of light may be performed after the process of determining the volume.

As described above, in the determination device 3 of the first embodiment, from the sensor unit 2 (an example of a “sensor”) that obtains environmental information about the environment including at least one of the amount of light and sound volume on the bed, Acquisition unit 30 (an example of an “acquisition unit”) that acquires the measurement signal of and a control unit 36 (“determination unit”) that determines whether the environment is appropriate based on the measurement signal acquired by the acquisition unit 30 An example of) and. As a result, in the determination device 3 of the first embodiment, even if the patient room and the individual beds arranged in the patient room are in an environment where the amount of light and sound volume are different, It is possible to determine whether the light amount and the sound volume are appropriate based on the light amount and the sound volume, and to determine whether the light amount and the sound volume actually perceived by the user in bed are appropriate. can be done.

Further, in the determination device 3, a memory for storing threshold information corresponding to the light amount level information and the threshold information corresponding to the sound volume level information (an example of the "determination standard") corresponding to the newborn baby (an example of the "bed user"). A control unit 36 (an example of a “determining unit”) determines that the amount of light is not appropriate when the amount of light indicated by the measurement signal exceeds the threshold value of the amount of light. If the indicated volume exceeds the volume threshold, it is determined that the volume is not appropriate (an example of “determining whether the environment is appropriate based on the measurement signal”). Thus, in the determination device 3 of the first embodiment, it is possible to determine that the light intensity is not appropriate by comparing the light intensity threshold stored in advance with the measured light intensity. Further, by comparing the volume threshold stored in advance with the measured volume, it can be determined that the volume is not appropriate. Accordingly, the determination device 3 can easily determine whether or not the amount of light and the sound volume are appropriate.

Further, in the determination device 3 , the bed may be a bed of a nursing container 51 (an example of a “nursing container”) that accommodates a newborn baby, and the sensor unit 2 (an example of a “sensor”) may be a bed of the nursing container 51 . It may be installed inside the housing. Thus, in the determination device 3 of the first embodiment, it is possible to determine whether or not the light amount and sound volume are appropriate based on the light amount and sound volume inside the nursery container 51 measured by the sensor unit 2. Therefore, it can be determined whether or not the amount of light and the sound volume perceived by the newborn baby housed in the nursery container 51 are appropriate.

In addition, in the determination device 3, using at least one of numerical values, characters, graphics, colors, sounds, and lights, the control unit 36 (an example of the “determination unit”) outputs the determination result. It further includes an output unit 34 and a display unit 35 (an example of an “output unit”). As a result, in the determination device 3 of the first embodiment, it is possible to display the measurement result measured by the sensor unit 2 and the determination result of determining whether the light amount and sound volume are appropriate. It is possible to inform the user of the device and medical personnel in the vicinity at a glance whether or not the amount of light and the volume are appropriate. In addition, even when the user of the bed or a medical worker in the vicinity cannot see the display of the determination device 3 during another treatment, the amount of light and the volume are appropriate due to the sound and light. can let you know whether or not

(Second embodiment)
Next, a second embodiment will be described. FIG. 5 is a configuration diagram showing the configuration of a determination device 3A according to the second embodiment. In the following description, the same reference numerals are given to the same configurations as those of the first embodiment, and the description thereof will be omitted.
In the determination device 3A of the second embodiment, the storage unit 33A stores the environment determination criteria according to the user of the bed. Specifically, as shown in FIG. 5, in the determination device 3A of the second embodiment, a patient situation database 335 and a situation correspondence database 336 are stored in the storage unit 33A.

In the determination device 3A of the second embodiment, the threshold is set according to the user of the bed. A user of the bed is, for example, a newborn using the incubator 5 . That the threshold is set according to the user of the bed means that the threshold is set based on the age of the newborn in weeks, for example. For example, it is said that the organs of the eyeballs that perceive light are not sufficiently functioning in newborns who are less than 28 weeks old (Neonatal Care 2016 vol.29 no.11 (1060)). Since such newborns are less responsive to light stimuli than older newborns, a darker environment that is closer to the environment in the mother's body is preferred. In addition, there is a possibility that underdeveloped eyeballs exposed to light may have effects such as poor organ development. For this reason, a darker state is preferable, and it is necessary to limit the amount of light that illuminates the interior of the nursery container 51 so as to maintain a particularly dark state for newborns aged 28 weeks or more. In the determination device 3A of the second embodiment, the threshold can be set based on the age in weeks of the patient (neonatal), and it can be determined whether or not the light amount and sound volume are appropriate according to the age in weeks. . However, the setting of the threshold is not limited to that based on the age in weeks. For example, since there are individual differences in response to light, the threshold may be set according to the development of eyes and ears, and the progress of treatment. Thus, in the determination device 3A, a threshold is set according to the user on the bed.

FIG. 6 is a diagram showing the data configuration of a storage unit 33A used in the determination device 3A of the second embodiment. FIG. 6(a) shows the data configuration of the patient status database 335. FIG. FIG. 6B shows the data configuration of the situation correspondence database 336. As shown in FIG.

As shown in FIG. 6A, the patient status database 335 stores patient IDs and age information. A patient ID is information that identifies a patient (for example, a patient identification number). Age in weeks information is information indicating the age in weeks of a patient (newborn baby). The example of FIG. 6(a) shows an example in which "30" is stored in the age-in-week information. The patient ID may be information for identifying the bed (for example, bed ID), or may be information for identifying the user who uses the bed although he is not the patient (for example, user ID). Note that the age-in-week information may be information indicating the weight of the newborn (weight information). It is conceivable that some health care workers may try to grasp the developmental situation by considering the weight as well as the age of the newborn. The number of weeks may also be a corrected number of weeks used for preterm newborns. This is because using the corrected number of weeks based on the expected date of birth rather than the number of weeks after birth based on the date of birth enables a more accurate grasp of the developmental situation.
The patient status database 335 includes the patient ID and stores age-in-week information in association with the patient ID, so that the age-in-week of each patient can be stored. Thereby, 3 A of determination apparatuses can determine whether a light quantity and a sound volume are appropriate according to a patient's age in weeks.

As shown in FIG. 6B, the situation correspondence database 336 stores age information and threshold information. The age-in-week information is information corresponding to the age-in-week information of the patient situation database 335 . The threshold is information indicating the upper limit of the allowable amount of light. In the example of FIG. 6(b), the upper limit of the amount of light for creating a dark state closer to the environment inside the mother's body is set as the light amount threshold for newborns aged 0 to 28 weeks. Specifically, 20 [lx] is stored as the light amount threshold. In addition, the upper limit of the amount of light that does not give light stimulation is set for newborns aged 28 to 34 weeks. Specifically, 30 [lx] is stored as the light amount threshold. In the example shown in FIG. 6B, the situation correspondence database 336 stores the threshold value for the amount of light, but is not limited to this, and may store the threshold value for the volume. A threshold corresponding to each may be stored.
The threshold may be set for each time period (for example, set separately for nighttime and daytime). For example, the nighttime threshold corresponding to 28 to 34 weeks of age may be 30[lx] and the daytime threshold may be 200[lx]. In this case, the determination device 3A, for example, refers to the situation database 336 according to time information indicated by a timer (not shown) provided therein, and uses a threshold according to the set level. Also, the threshold value may indicate the absolute value of the amount of light or sound volume at that moment, or may indicate the amount of relative change. When the threshold value indicates the amount of change, for example, the determination device 3A determines that the light amount is not appropriate when it suddenly becomes bright even if the amount of light is small.
Also, the threshold may be a threshold that indicates the lower limit of the allowable amount of light or volume. In this case, the determination device 3A determines that the light amount is not appropriate when the light amount measurement value is below the lower limit threshold. Further, the determination device 3A uses both the upper threshold and the lower threshold, and determines that the light intensity is appropriate when the light intensity measurement value falls within the range from the lower threshold to the upper threshold. can be An environment with no light or sound does not necessarily have a positive effect on brain development. For example, it is said that a newborn baby weighing about 600g needs to be completely dark and not make too much noise for development, but a newborn baby weighing about 2600g needs to distinguish between daytime and nighttime and a certain amount of sound for development. there is In such a case, it may be judged appropriate if the weight of the newborn does not fall below the lower threshold or if the measured value falls between the lower threshold and the upper threshold.

The input unit 31 outputs an externally input operation signal to the control unit 36 . The operating signals include a signal identifying the patient and a signal representing the age of the patient.

The control unit 36 causes the storage unit 33 to store the operation signal from the input unit 31 . The control unit 36 causes the patient status database 335 to store the information identifying the patient and the information indicating the age in weeks among the operation signals. Specifically, the information for identifying the patient is stored in the patient ID, and the age in weeks of the patient is stored in the age in weeks information.

The control unit 36 acquires the threshold corresponding to the age in weeks of each individual patient, stored in the storage unit 33A. Specifically, the control unit 36 refers to the patient condition database 335 and acquires age information. Then, the control unit 36 refers to the situation correspondence database 336 and acquires a threshold value corresponding to the acquired age-in-week information. More specifically, in the example of FIG. 6, the control unit 36 acquires the age in weeks information of the patient situation database 335, and changes the age in weeks of "28 to 34" in the situation correspondence database 336 including the acquired age in weeks of "30". acquires the threshold "30 [lx]" corresponding to ".

As described above, in the determination device 3A of the second embodiment, the threshold information corresponding to the light amount level information and the threshold information corresponding to the sound volume level information ("bed user The storage unit 33 (an example of the “storage unit”) stores the “determination criteria for the environment according to the environment”), and the control unit 36 (an example of the “determination unit”) determines whether the light amount indicated by the measurement signal exceeds the light amount threshold. If it exceeds, it is determined that the amount of light is not appropriate, and if the volume indicated by the measurement signal exceeds the volume threshold, it is determined that the volume is not appropriate ("The environment is appropriate based on the measurement signal and the criteria an example of “determine whether or not”). As a result, in the determination device 3A of the second embodiment, in addition to the same effects as in the first embodiment, it is possible to perform determination using a threshold set according to the state of the bed user. Thereby, the determination device 3A can determine whether or not the light amount and the sound volume are appropriate according to the bed user.

The incubator 5B also includes a noise canceling section 56 that reduces noise inside the incubator container 51 .
The drive unit 55 rotates the roll in a certain direction to roll down the cover 511B so that the nursery container 51 is shielded from light. In addition, the drive unit 55 rotates the roll in the opposite direction to wind up the cover 511B so that the nursery container 51 is illuminated with light such as illumination.
The noise canceling unit 56 inputs the noise inside the nursery container 51, for example, and outputs a sound having a phase opposite to that of the noise, thereby making the noise difficult to hear.

The control unit 36 outputs to the adjustment unit 38 the determination results as to whether or not the amount of light and the sound volume are appropriate. The light amount adjustment unit 380 outputs a light amount adjustment signal for adjusting the light amount when the control unit 36 determines that the light amount is not appropriate based on the determination result from the control unit 36 . The light amount adjustment signal includes a signal indicating the direction in which the drive unit 55 is driven. The volume adjustment unit 381 outputs a volume adjustment signal for adjusting the volume when the control unit 36 determines that the volume is not appropriate based on the determination result from the control unit 36 . The volume adjustment signal includes a signal indicating that the noise cancellation section 56 should start operating.

As described above, in the determination device 3B of the third embodiment, the light irradiated to the nursery container 51 (an example of the bed) is blocked based on the determination result by the control unit 36 (an example of the determination unit). , further includes a light amount adjustment unit 380 that adjusts the amount of light indicated by the measurement signal.

(Modification of embodiment)
The determination device 3B of the present embodiment may control the illumination of the hospital room in order to adjust the amount of light applied to the nursery container 51 . In this case, the hospital room is equipped with a light controller that adjusts the amount of illumination. If the control unit 36 determines that the light amount is not appropriate based on the determination result from the control unit 36, the light amount adjustment unit 380 outputs a control signal for adjusting the light amount of the hospital room illumination to the light controller. At this time, the light amount adjusting section 380 outputs a control signal for adjusting the light amount of the illumination installed at the position closest to the place where the incubator 5 is arranged, for example. As a result, the determination device 3B of the present embodiment can determine whether or not the amount of light is appropriate, and can adjust the amount of light when it is determined that the amount of light is not appropriate.
