BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, in order to clarify the present invention more specifically, specific examples of the present invention will be described in detail with reference to the drawings.

First, FIG. 1 shows an insulin injection instructor 10 as an embodiment of the present invention,
Insulin injection system 14 combined with 2
Is shown schematically.

In the insulin injection system 14, the insulin syringe 12 is a conventional one used for injecting a predetermined amount of insulin into a diabetic patient subcutaneously. Specifically, the syringe body 12 has a cylindrical shape. An ampoule 18 filled with a predetermined insulin can be loaded into the inside of the syringe body 16, and an injection button 20 provided at one end of the syringe body 16 is pushed to operate the piston member provided in the syringe body 16. The internal pressure in the ampoule 18 is increased by a predetermined operation such as (not shown), and insulin is punctured at a predetermined amount through the inner hole of the puncture needle 22 provided at the other end of the syringe body 16. The structure is such that the tip of the needle 22 can be injected outside the syringe body 16.

Further, in the present embodiment, the injection button 20 of the insulin syringe 12 also has a function of setting the amount of insulin to be injected (injection amount), and is provided at the end of the syringe body 16 on the side of the injection button 20. The injection volume can be set by rotating the injection button 20 in the circumferential direction so that the value of the dial-type injection volume setting scale 24 becomes a desired value.

Further, here, the syringe body 16 is formed of two divided bodies 26 and 28, and the puncture needle side divided body 26, which is one of the divided bodies, is separated from the other button side divided body 28. In the above, the ampule 18 containing predetermined insulin is inserted into the puncture needle-side divided body 26 and fixed, and then the divided bodies 26 and 28 are screwed together again. It can be loaded.

In short, such an insulin syringe 1
In order to perform an injection using the insulin injection system 14 having an injection syringe 2, first, the ampoule 18 is filled in the syringe body 16 of the insulin syringe 12, and then the injection amount is adjusted by rotating the injection button 20. After performing the setting, a predetermined operation of the insulin syringe 12 (hereinafter, abbreviated as injection operation), that is, the insulin injection system 14 is grasped with a finger, and the tip of the puncture needle 22 is punctured into a predetermined site such as the abdomen of the patient. At the very least, the injection button 20 is pressed and operated, and a predetermined amount of insulin is injected or injected into the patient's body by such a series of injection operations.

On the other hand, the insulin injection instructor 10 constituting the insulin injection system 14 is used by being attached to such an insulin syringe 12, and is formed here by a circuit capable of performing a predetermined operation. On the other hand, by being accommodated in the rectangular box-shaped case 30 extending in a predetermined length in one direction, it is integrated with the insulin syringe 12 and carried with the insulin syringe 12. It is possible.

Specifically, the case 30 accommodating the insulin injection instructor 10 has a length shorter than the button-side split body 28 of the insulin syringe 12 and corresponds to the outer shape of the syringe body 16 of the insulin syringe 12. It has an assembling hole 32 extending in the longitudinal direction with a shape, and can be inserted into the insulin syringe 12 at the assembling hole 32. Further, as shown in FIG. 1, the case 30 has a structure which is externally inserted into the insulin syringe 12 and can be fixed to the insulin syringe 12 at the button-side split body 28 so as not to be displaceable. The above-described work of loading the ampule 18 can be performed without releasing the fixed state between the insulin syringe 12 and the case 30. Further, in the case 30, it is also possible to remove the case from the insulin syringe 12 by releasing the fixed state, whereby maintenance of the insulin syringe 12 and adjustment of the insulin injection instructor 10 and the like can be performed. Implementation is easier. In this case, Case 3
Needless to say, when performing the extrapolation or detachment work on the insulin syringe 12 of 0, the circuit constituting the insulin injection instructor 10 in the case 30 is not adversely affected at all. It is a place.

The insulin injection instructor 10 of the present embodiment housed in such a case 30 has a configuration as conceptually shown in a block diagram in FIG.

That is, the insulin injection instructor 10 comprises:
A central processing unit 56 including a CPU 50, a ROM 52 and an I / O interface 54 connected to the CPU 50, and an operation unit 58 including specific modules, sensors and mechanisms connected to the I / O interface 54

In addition to the OM 52 and the I / O interface 54, a timer module 60 that performs accurate time measurement and constantly outputs the measured time as time information.
And a memory module 62 composed of a RAM capable of storing data. Further, both of the timer module 60 and the memory module 62
It is possible to directly exchange information by designating an address from the PU 50, so that the operation in those modules 60 and 62 can be controlled and managed by the CPU 50, similarly to the operation unit 58. It is like that.

On the other hand, the operation section 58 is provided with the injection information detecting mechanism 6.
4, input module 66, warning / notification module 68,
On the other hand, the injection information detecting mechanism 64 is composed of an operation start point detection sensor 76, a type identification sensor 78, and an injection amount detection sensor 80, and includes a syringe lock mechanism 70, a display module 72, and a communication module 74. The state of a specific injection operation to be performed can be detected.

In the injection information detecting mechanism 64, the operation start point detecting sensor 76 detects the start point of the predetermined injection operation for injecting insulin,
It is configured to output an operation start point detection signal. As the operation start point detection sensor 76 capable of performing such an operation, for example, the insulin syringe 1
2, a micro switch or a limit switch is disposed at the operation site of the injection button 20, in other words, from when the injection button 20 is pressed until the insulin is actually ejected from the puncture needle 22. In the play section of the injection button 20, in addition to the trigger signal output as the operation start time detection signal, the surface of the part of the insulin syringe 12 or the case 30 that the patient grips with his / her finger, By providing a metal or carbon fiber electrode connected to the puncture needle 22 made of a metal conductor by wiring or the like, the patient punctures the puncture needle 22 at a predetermined part of the body, and the electrode, An electric loop composed of the puncture needle 22 and the patient's body and the like is formed so that it can be formed. A trigger signal is output by detecting a change in impedance or voltage caused by the formation, or a metal or carbon fiber on the surface of a part of the insulin syringe 12 or the case 30 that the patient grips with fingers. By piercing the patient with the puncture needle 22 by providing an electrode made of
In this case, a change in voltage resulting from the activity of the cardiac myocytes in the heart, that is, a so-called electrocardiogram is detected, and a trigger signal is output.

The operation start point detection sensor 76 is formed by various types of conventionally known electric circuits which can advantageously realize the above-described components. In the case of employing such a configuration, it is more desirable to provide a circuit capable of improving the SN ratio of the detected electrocardiographic signal.

The type identification sensor 78 identifies the type of insulin to be injected, that is, the type of insulin enclosed in the ampule 18 filled in the syringe body 16 of the insulin syringe 12 and directly determines the type. For example, a barcode or a magnetic record that gives the type of insulin is provided on the outer peripheral surface of the ampoule 18 or a type identification signal is output on the outer peripheral surface of the ampoule 18. In addition to those that have been colored in the color that was done and read it without contact,
Protrusions of a shape corresponding to the type are provided on the outer peripheral surface of the ampoule 18 and can be advantageously formed, for example, by contact reading with a mechanical switch or the like.

Further, the injection amount detection sensor 80 detects the injection amount injected by the insulin syringe 12, and outputs an injection amount detection signal indicating the injection amount directly or indirectly. Here, such a detection signal is obtained based on the setting of the injection amount by the injection button 20. As such an injection amount detection sensor 80, for example, an injection amount setting mechanism of the injection button 20 as described above is used so that an electric signal corresponding to the rotation position can be output as an injection amount detection signal. , A rotary potentiometer or the like can be advantageously employed.

On the other hand, the input module 66 provided in the operation section 58 includes a time slot for the patient to inject insulin (injection time slot), and the type and amount of insulin to be injected in the injection time slot. Are used for inputting and setting information (injection information) relating to predetermined injection work. As such an input module 66, a relatively small input device such as a button-type input device is used, and is disposed on the outer peripheral surface of the case 30. A device for inputting injection information may be advantageously employed, but various external input devices such as a keyboard are directly connected by cables.
Alternatively, the input module 66 is configured by various known interfaces for indirect connection by infrared rays or the like, and the external input device is connected thereto, and the injection information is indirectly connected via the external input device. There is no problem even if the user inputs "". In addition, the injection information is usually determined as a basic unit for one day. For example, in a case where a plurality of injections are performed in one day, a plurality of injection time zones are set, The type of insulin and the amount of injection are set for each time slot.
In addition, here, band injection time, the range of the beginning and the end of time: is adapted to be defined by the T _s and T _e. Furthermore, in the present embodiment, it is also possible to set the time in the timer module 60 and delete the data stored in the memory module 62 through the input module 66.

Further, in the operation unit 58, the warning / notification module 68 generates an oscillating sound, a melody, a sound such as a voice, light, vibration, etc. in accordance with a control command from the CPU 50. A prescribed warning or notice can be given to the patient. Incidentally, the warning / notification module 68 as described above includes various known sound sources (including a sound generator) conventionally used in an alarm device, a light source such as a light bulb or a light emitting diode, and a vibration generator such as a vibrator. One or a combination of a plurality of the above may be advantageously employed, but preferably, a combination of the plurality is employed to improve the effectiveness of the warning / notification function. It is desirable. In addition, the sound source, the light source, the vibration generator, and the like used as the warning / notification module 68 are different types of sounds,
It must be able to generate light, vibration, etc.
More desirable. In the case where a sound source is adopted, for example, such a warning / notification module 68 can change its timbre, generation time and tune, and can directly express the contents of an error by voice. Can be advantageously realized.

Further, the syringe lock mechanism 70 locks the injection button 20, receives a control command (syringe lock signal) output from the CPU 50, and sets the injection button 20 of the insulin syringe 12 to the syringe body. 16 so that the injection button 2
The structure is such that the pushing operation of 0 can be restricted. As the fixing structure of the injection button 20, various known structures can be employed. The fixing structure includes a structure for directly fixing the injection button 20 and a structure for fixing the piston member connected to the injection button 20. Although the injection button 20 is indirectly fixed by fixing the above, there is no problem in any case. In the case of the injection information detecting mechanism 64, when the operation start time point detection sensor 76 is configured by a micro switch or a limit switch disposed at the operation site of the injection button 20 of the insulin syringe 12 as described above, It is desirable that the injection button 20 be allowed to operate within the play section even under the operating state of the syringe lock mechanism 70, so that the detection by the operation start point detection sensor 76 can be effectively performed.

In the operation section 58, the display module 72 is formed of various known display devices such as a liquid crystal panel, and here, under the control of the CPU 50, displays predetermined data and information. It can be displayed on the screen.

Further, in the operation section 58, as described above, the communication module 74 having a function of outputting predetermined data to the outside is provided. Such a communication module 74 can be configured by various known communication devices, but advantageously, a modem or a wireless device is suitably adopted as the communication module 74.
Thereby, predetermined data is output to an external display device (not shown) provided outside the insulin injection instructor 10 via a telephone line or wirelessly,
By transmitting the data, the data can be displayed on the external display device. Note that the communication module 74 only needs to be able to output data at least to the outside. Therefore, there is no problem even if it is a one-way communication type that can output only data. If necessary, it is of course possible to use a two-way communication type that enables input of information and the like from outside as well as data output. In addition, the communication module 7
The interface 4 can be constituted by various known interfaces that enable direct or indirect connection to a modem or a wireless device. The same function as described above can be achieved by connecting a modem or a wireless device provided in the PC.

In addition, the insulin injection instructor 10 includes:
Primary batteries such as dry batteries, mercury batteries, and lithium batteries; secondary batteries such as nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries; or power lines (outlets)
A battery 82 is provided, which is composed of various known power supply devices and the like that can supply electric power from the central processing unit 56 and the operation unit 58. It has become so. Also, this battery 8
Although not clear from FIG. 2, a sensor for detecting the remaining amount of the electric energy is attached to 2, and the remaining amount information corresponding to the detected value is output. In the insulin injection instructor 10, the battery 82
Even if the remaining amount of power becomes zero, a backup battery is provided so that the stored contents in the memory module 62 and the time setting in the timer module 60 can be reliably protected. desirable.

Thus, in such an insulin injection instructor 10, a predetermined operation is performed in accordance with the program written in the ROM 52. That is, when using the insulin injection system 14 provided with the insulin injection instructor 10, first, the patient or his / her physician should be injected through the input module 66 in the injection time zone or the time zone. Predetermined injection information such as the type and amount of insulin is to be input and set in advance in the insulin injection instructor 10. In the insulin injection instructor 10, such injection information input operation is performed. Are read by the CPU 50, are grouped by a predetermined process, and are stored in the memory module 62 as set injection data. The set injection data is updated every time the input is made in accordance with the change of the injection information. In other words, once the injection information is input, the storage of the set injection data in the memory module 62 is held unless the change or the erasing operation of the memory module 62 is performed.

Further, in the insulin injection instructor 10, when the set injection data is stored in the memory module 62, the output from the timer module 60 is based on the information on the injection time zone in the set injection data. Monitoring of the current time recognized from the time information performed is performed. Then, under such a monitor, the current time, set injectable hours beginning time: at the time it reaches the T _s, in response to the warning, notification module 68 from the CPU 50, the control command (injection time period notification signal ) Is output, and the warning / notification module 68 is operated, and the patient is notified by sound or the like that the prescribed injection time zone has come. Note that such notification is made at the time of the end of the set injection time zone: T _e
In the meantime, continuously or at an appropriate time interval until the injection operation is correctly performed by the patient and the insulin is appropriately injected into the patient's body as described later. It is desirable to be implemented intermittently. In the present embodiment, a warning
Along with the notification by the notification module 68, the set injection data is displayed on the display screen of the display module 72, and the patient can visually confirm the type and amount of the insulin to be injected during the time period. Can be grasped.

Further, upon receiving the notification, or in spite of such notification, the patient fills the insulin syringe 12 with the ampoule 18 in which insulin is filled and presses the injection button 20 except for the injection time slot. Is rotated to adjust the amount of injection, and then the above-mentioned predetermined injection operation is performed in order to inject insulin. In the insulin injection instructor 10, first, at the start of the injection operation, Operation start point detection sensor 76
The operation start time detection signal output from the central processing unit 5
6, the time at the time of the reading, that is, the time at the start of the injection operation, is obtained based on the time information output from the timer module 60. At the same time, when the operation start time detection signal is read into the central processing unit 56, the type identification signal and the injection amount detection sensor 80 output a type identification signal and an injection amount detection signal from the central processing unit 56, respectively. It will be taken into the processing unit 56. After the type identification signal, the injection amount detection signal, and the time at the start of the injection operation are converted into type information, injection amount information, and operation start time information by the processing in the CPU 50, respectively, the information is They are put together and stored in the memory module 62 as detected injection data relating to the injection work of the patient. Further, in the CPU 50, the memory module 6
The detected injection data stored in the memory module 62 is compared with the set injection data previously stored in the memory module 62, and the operation start time information, type information, and injection amount information constituting the detected injection data respectively correspond to the detected injection data. Then, it is determined whether or not (適合 す る) or not (×) matches the information on the injection time zone and the type and amount of insulin in the set injection data.

In this case, the judgment becomes x. In short, when it is judged that there is an error in at least one of the injection time, the kind of insulin and the injection amount in the injection work of the patient, A control command (misfire warning signal) is output from the CPU 50 to the warning / notification module 68, and based on the control command, a predetermined warning such as a sound is issued to the patient. Thus, a syringe lock signal is output, and the syringe lock mechanism 70 restricts the pushing operation of the injection button 20 in the insulin syringe 12, thereby forcibly preventing the injection of insulin into the patient. . The warning issued by the warning / notification module 68 allows the patient to easily understand which of the injection time, the type of insulin, and the injection amount is wrong. It is preferable that a plurality of types of misfire warning signals corresponding to the error situation be generated by the CPU 5.
0, and the warning / notification module 68 is configured to generate different types of sounds, light, vibrations, etc. in response to each of such misfire warning signals. , Can be advantageously achieved. Further, it is more desirable that such a warning can be easily distinguished even from a notice informing the injection time zone. Further, the duration of the warning and the operation time of the lock function are set at appropriate lengths as needed. Furthermore, the syringe lock mechanism 70 allows the insulin puncture needle 2 of the insulin syringe 12 to be moved by the injection operation.
It goes without saying that it is activated before it is fired from 2.

In the insulin injection instructor 10 of the present embodiment, when the judgment based on the collation between the detected injection data and the set injection data is X, the warning by the warning / notification module 68 as described above, In addition to the locking function of the injection button 20 by the locking mechanism 70, the display module 72 can display what is wrong in the injection operation of the patient, and visually warn of a mistaken shot. It is like that.

Further, the warning / notification module 68
And warning by the display module 72 and the syringe lock mechanism 7
When the patient recognizes that the type and amount of insulin is wrong by correcting the lock operation of 0, corrects or changes the replacement of the ampoule 18 or the setting of the injection amount, and then performs the injection operation again, In the insulin injection instructor 10,
The same processing as described above is performed, so that the determination based on the comparison between the detected injection data and the set injection data can be performed again, as long as the determination is ×,
The warning and injection button 20 is locked. Of course, the above warning and the syringe lock mechanism 70
Regardless of the operation of, the injection operation is performed again in the wrong time zone, or the injection operation is performed again without changing or changing the setting of the ampoule 18 or the injection amount. Then, a determination based on the comparison between the detected injection data and the set injection data is performed, and the warning operation and the locking of the injection button 20 are executed.

On the other hand, when the first determination is 判定, or after the determination of ×, the type of insulin is changed and / or the injection amount is corrected, so that the determination of ○ is made. That is, when it is determined that the injection time zone, the type of insulin and the injection amount are as specified, the warning function in the warning / notification module 68 and the display module 72 and the locking function of the syringe locking mechanism 70 are:
Without working or being released, the injection operation by the patient will be completed without any hindrance,
Insulin is to be injected correctly and appropriately into the patient's body. In the present embodiment, the injection time, the type of the injected insulin, and the injection history, which is the amount of the injected insulin, are associated with this. The data is stored in the memory module 62.

More specifically, in the CPU 50, the operation start time information in the detected injection data is converted into injection time information. Subsequently, the obtained injection time information, the type information in the detected injection data, After the injection history data including the amount information as a group of data is formed, the injection history data is sequentially and temporally stored in the memory module 62. In short, each time insulin is correctly injected into a patient, the injection history data giving the history is automatically stored in the memory module 62. Here, the operation start time information converted into the injection time information is
Depending on the conversion, the data is not erased in the memory module 62.

In the present embodiment, the injection history data, the detected injection data and the set injection data stored in the memory module 62 are subjected to a predetermined external input through the input module 66. , Can be displayed on the display module 72, and these various data can be always checked. Further, the injection history data stored in the memory module 62 is externally output from the communication module 74 in accordance with a predetermined external input. However, the external input performed for performing the output from the communication module 74 includes not only the input performed through the input module 66 but also the bidirectional communication type when the communication module 74 is used. What is done through the communication module 74,
Intended.

Furthermore, in the insulin injection instructor 10 of the present embodiment, the time information output from the timer module 60 is displayed on the display module 72 at all times or by the execution of an external input, and a normal clock is displayed. And the remaining power information output from a sensor for detecting the remaining power amount provided in the battery 82 is displayed, so that the remaining power amount can be easily grasped. It has become. Furthermore, based on the remaining amount information, when the remaining amount of power in the battery 82 becomes smaller than a predetermined value or becomes zero, a predetermined warning operation can be performed in the warning / notification module 68. It is also configured as follows.

In short, according to the insulin injection instructor 10 as described above, when the prescribed injection time is reached, the warning / notification module 68 notifies it,
Even if the patient has forgotten the injection time slot, the patient can surely know the injection time slot, and despite such notification, perform the injection operation outside the injection time slot, Further, an ampoule 18 in which a different type of insulin is sealed is inserted into the insulin syringe 1.
In the case where the injection operation is performed in a state where the injection amount is set to 2 or in a state where the injection amount is set incorrectly, by performing a collation process between the detected injection data and the set injection data,
After the determination of the nonconformity (x), a predetermined warning is given to the patient by the warning / notification module 68 and the display module 72, and the injection button 2 of the insulin syringe 12 is
Since 0 is locked, the patient can easily recognize by such a warning or locking action that there is an error in the injection operation regarding any of the injection time, the type of insulin, and the injection amount, and By the locking function of the syringe locking mechanism 70, the injection of insulin into the patient can be forcibly prevented, and as a result, erroneous injection of insulin is effectively and reliably prevented or prevented. .

In the present embodiment, not only the notification by the warning / notification module 68 but also the set injection data is displayed on the display screen of the display module 72 in a predetermined injection time slot. Since the type and amount of insulin to be injected in the band can be visually confirmed, injection work such as filling of the ampoule 18 and setting of the injection amount can be performed while watching such display contents. You can do it properly.

Therefore, if the insulin injection system 14 in which the insulin injection instructor 10 is attached to the insulin syringe 12 is used, the injection operation of the patient is properly instructed, and the insulin injection into the patient's body can be performed. It can be performed properly in the correct type and amount at the time of injection, and as a result, the blood glucose level of the patient can be maintained well, and misdiagnosis can be prevented. It is.

In addition, in the insulin injection instructor 10 of the present embodiment, since the injection history data stored in the memory module 62 can be displayed on the display module 72, the patient can Therefore, the insulin injection history can be grasped very easily. Further, if a modem or a wireless device is adopted as the communication module 74, the injection history data is output and transmitted to an external device such as a computer system including a monitor and a printer owned by the doctor via a telephone line or wirelessly. Since the injection history data can be displayed on the monitor or printed out by a printer, the doctor can easily and reliably grasp the injection history of the patient from the obtained injection history data. As a result, a more precise and reliable diagnosis can be performed, so that a misdiagnosis can be more advantageously avoided. In particular,
By configuring the communication module 74 with a two-way communication type modem, a wireless device, or the like, the doctor can
Injection history data can be obtained, and such an effect is more effectively exerted.

Although the representative embodiment of the present invention has been described in detail, it is merely an example, and the present invention is not limited to any specific description according to such an embodiment. Needless to say, it is not to be construed as limiting.

For example, the insulin injection instruction device according to the present invention can be applied to any of various known insulin syringes that can inject or inject insulin into a patient by a predetermined operation. It goes without saying that a combination having a structure different from that of the insulin syringe 12 can be used.

Further, in the illustrated embodiment, all the components of the insulin injection guidance device are integrated into the insulin syringe by being housed in a predetermined case. Is divided into a plurality, and one of them is integrally attached to the insulin syringe, and one configured to connect it to the other by a cable or infrared light,
Also, it is included in the category of the present invention. In addition, such a configuration has an advantage that the operability of insulin injection can be improved because the number of components to be attached to the insulin syringe can be reduced to a minimum and the size can be reduced as a whole.

Further, the "injection information" in the present invention is not limited to the example as long as it is information relating to the injection operation of insulin. As one of the injection information to be compared with the preset injection information such as the type and amount of insulin to be injected in the time zone to be injected, the injection time zone, etc., it is appropriate to confirm the correctness of the injection work. The external input execution time can be adopted, whereby the insulin container is set in the insulin syringe, and after setting the amount of injection, a predetermined external input is performed prior to performing the operation of the insulin syringe. Thus, the type, amount, and time of the insulin at the time of the input are compared with the preset injection information, and they are compared with each other. If no match is made and an alarm is issued by the alarm means, Te than the patient, before actually performing the injection operation, it become possible to perform confirmation of injection operations.

Furthermore, in the above-described embodiment, the warning / notification module 68 is configured to notify the time zone to be injected or to warn of a missed shot, but these functions are performed by separate devices. It is, of course, possible to configure it to be fulfilled.

Further, in the illustrated embodiment, a mechanism for restricting the pushing operation of the injection button of the insulin syringe has been adopted as the erroneous injection prevention locking mechanism for locking the injection operation of the insulin syringe. It is not a thing that can be performed, so long as it can lock the operation of the insulin syringe so that the insulin is not ejected from the puncture needle of the insulin syringe. The following form can be adopted. In addition, as the misfire prevention lock mechanism of the present invention, besides the above-described structure configured to operate based on the mismatch information by the determination means, the lock mechanism operates based on the insulin misfire alarm by the alarm means. Those can also be advantageously employed. Furthermore, the misfire prevention lock mechanism is released only when a match is determined by the determination means. In other words, even if the lock operation is performed as long as the two pieces of injection information do not match, any lock operation is not performed. No problem.

Further, the detection mechanism for detecting the time at which the operation of the insulin syringe is started is not limited to the above-described embodiment. For example, the input mechanism such as the input module 66 may be used to detect the insulin. In starting the operation of the syringe, a predetermined input can be made by the input device, and the operation start time of the insulin syringe can be detected based on the input.

Further, storage means (memory module 6)
As 2), a RAM is used in the illustrated embodiment, but the present invention is not limited to this, and various known storage devices or storage media can be used. For example, a floppy disk (FD) ), Hard disk (H
D), a magnetic card, and the like, which are appropriately selected and used according to the size and price required of the insulin injection guidance device, the amount of information to be stored, and the like. Furthermore, in such a storage means, not only the injection history at the time of correct injection, but also
There is no problem if a misfire record in the event of a misfire is also stored.

In addition, in the above embodiment, the communication module 74 may be constituted by an interface that enables connection with an external device such as a computer system. By causing the external device to output the injection information and the injection history and displaying or printing the information on a monitor or a printer provided therein, the patient can effectively grasp the injection information and the injection history. You will get. Further, as described above, by adopting a two-way communication type as the communication module 74, a doctor or the like can use the communication module 74 instead of the input module 66 so that a doctor or the like can inject insulin at a time zone or the like. It is also possible to configure so as to input predetermined injection information such as the type and amount of insulin to be injected in the time zone.

In addition, although not enumerated one by one, the present invention
Based on the knowledge of those skilled in the art, the present invention can be implemented in a form in which various changes, modifications, improvements, and the like are made.
As long as such an embodiment does not depart from the gist of the present invention, it is supposed that any of the embodiments belongs to the scope of the present invention.
Needless to say.

As is clear from the above description, according to the insulin injection guidance apparatus according to the present invention, the notification function of the notification means allows the patient to ensure that the preset time zone for injection has arrived. When the injection operation of the patient is erroneous, the alarm is issued by the alarm means based on the judgment by the judging means. Can be prevented beforehand. Therefore, if such an insulin injection guidance device is used by attaching it to an insulin syringe, the patient can correctly inject insulin into the body, and therefore, the blood sugar level of the patient can be maintained well. It also plays a role in preventing misdiagnosis.
