The storage device 4 may be a storage device provided in the server 3.

(1.2 Functional configuration of portable terminal 2)
With reference to FIG. 2, the functional configuration of the portable terminal 2 will be described. The CPU 10 of the portable terminal 2 reads out the program stored in the storage device 22 to the main memory 21 and executes it, whereby the medical information acquisition unit 11, the position information acquisition unit 12, the schedule setting unit 13, the information management unit 14, The chart input management unit 15 and the like are realized.

The medical information acquisition unit 11 acquires medical information from the server 3 and stores it in the main memory 21 and the storage device 22. The medical information is, for example, the following information.
・ Destination information such as list of patients scheduled to visit and patient's home address ・ Patient information such as medical records of each patient and record of test results ・ Record information used for recording in home medical care ・ Users who use portable terminal 2 ID information such as the ID of the transmitter 71 and the ID of the transmitter 71 (in the case of the second embodiment) Various medical information is associated with each patient.

  The position information acquisition unit 12 acquires the current position of the portable terminal 2 every predetermined time based on the GPS signal 6 (the transmitter signal 72 in the case of the second embodiment) received by the reception unit 29. The current position of the portable terminal 2 is sent to the information management unit 14.

  The schedule setting unit 13 sets a visit schedule based on the visited information out of the medical information acquired by the medical information acquisition unit 11 and stores it in the main memory 21 and the storage device 22. The visit schedule is, for example, a visit order, a scheduled visit time, a visit route, etc. of each patient's home that is scheduled to be visited, and is displayed on the display unit 27 together with a map (see FIG. 4).

  The planned position on the visit route including the patient's home and the time for staying or passing through the position are sent to the information management unit 14. In order to set a visit schedule, a positioning / map information processing or route searching method used in a car navigation system may be used, which is not described here.

  The information management unit 14 manages permission and restriction on the display of the patient information of the patient to be visited on the display unit 27 and deletion of medical information in the main memory 21, the storage device 22, and the display memory 24.

  When the portable terminal 2 is at the patient's home as scheduled or within a predetermined distance from the patient's home on the visited route, the information management unit 14 responds to the display request from the user with patient information. Is displayed on the display unit 27. When it is outside the range of the predetermined distance from the patient's home, it does not respond to the display request from the user.

  Moreover, even if the portable terminal 2 is on the patient's home or the visit route, if it is out of the scheduled time, the information management unit 14 not only does not respond to the display request from the user but also deletes the medical information. . Even when the portable terminal 2 is not on the patient's home or visit route, the information management unit 14 deletes the medical information.

  Such information management by the information management unit 14 is performed depending on whether or not the portable terminal 2 is at the scheduled time and position.

Whether the portable terminal 2 is at the scheduled time and position is determined as follows. The information management unit 14
-Scheduled time and position-Current time-Current position is acquired from the schedule setting unit 13, an internal clock (not shown), and the position information acquisition unit 12 at predetermined times, respectively, and the current position of the portable terminal 2 Then, it is determined whether or not the time matches the planned position and the scheduled time set by the schedule setting unit 13.

  For example, if the portable terminal 2 arrives at the patient's home (and its surroundings) at the scheduled time, it will be judged as coincidence. On the other hand, the arrival at the patient's home will be too early or delayed, or will not arrive due to some trouble. If it does, it will be judged as a mismatch.

  The determination of coincidence of time and position may be performed within a predetermined range. For example, a period of several tens of minutes may be provided at the scheduled time, and an area having a radius of several tens of meters may be provided at the planned position. The period and area range are set in advance in the program.

  By setting a range for the scheduled time and position, it is possible to display and confirm the patient information of the patient to be visited next on the display unit 27 in the course of the visit route. In this case, the information management unit 14 determines whether the current time and the current position of the portable terminal 2 are within the range of the scheduled time and position.

  The medical record input management unit 15 manages the display and non-display of the medical record information on the display unit 27, the transmission of the medical record additional information to the server 3, and the deletion of the medical information in the memory 21, the storage device 22, and the display memory 24. To do. Information management by the medical record input management unit 15 is performed in response to a medical treatment start instruction and a medical treatment end instruction from the input unit 28.

  When there is a medical treatment start instruction from the input unit 28, the chart input management unit 15 displays the chart information and the entry to the chart from the input unit 28 on the display unit 27. At this time, the chart input management unit 15 stores the entry in the chart in the main memory 21 and the storage device 22 as chart record additional information.

  When there is a medical treatment end instruction from the input unit 28, the medical record input management unit 15 transmits the medical record additional information to the server 3 and deletes the medical information of the patient who has finished the medical treatment from the main memory 21, the storage device 22 and the display memory 24. To do. Therefore, the medical information of the patient is not displayed on the display unit 27.

(1.3 Flow of medical information management process)
Next, the operation of the portable terminal 2 will be described with reference to FIGS.
FIG. 3 is a flowchart for explaining the flow of medical information management processing executed by the portable terminal 2. The CPU 10 of the portable terminal 2 reads the program and data related to the medical information management process shown in FIG. 3 from the main memory 21 and executes the process based on the program and data.

  First, the CPU 10 of the portable terminal 2 acquires medical information such as visit information, patient information, and user ID stored in the storage device 4 via the server 3 and stores them in the main memory 21 and the storage device 22 ( Step S101).

  Next, the CPU 10 sets a visit schedule and a visit route based on the acquired visit destination information and displays them on the display unit 27 (see step S102, screen display example 400 in FIG. 4).

  CPU10 acquires the present position of portable terminal 2 based on GPS signal 6 received by receiving part 29 (Step S103).

  Next, the CPU 10 determines whether or not the portable terminal 2 has arrived at the first patient's home as scheduled based on the current position of the portable terminal 2, the current time, and the set visit schedule (step). S104). When the portable terminal 2 arrives at the patient's home, that is, when the current position and the current time of the portable terminal 2 coincide with the planned patient's home position and the scheduled visit time (Y in step S104). The patient information is displayed on the display unit 27 (see the screen display example 500 in FIG. 5), and the GPS signal 6 is further received (step S107).

  On the other hand, when the portable terminal 2 has not arrived at the patient's home, that is, when the current position and the current time of the portable terminal 2 do not match the planned patient's home position and the planned visit time (step) The process proceeds to step S105, N) of S104.

  If it is determined in step S105 that the current time is within a predetermined time limit such as an adjustment time for which a visit delay is anticipated (Y in step S105), the CPU 10 returns to step S102 and resets the visit schedule. However, if the current time exceeds the time limit (N in Step S105), the CPU 10 deletes the medical information from the main memory 21, the storage device 22, and the display memory 24 (Step S106).

  Based on the GPS signal 6 received in step S107, the CPU 10 acquires the current position of the portable terminal 2 and determines whether the current position of the portable terminal 2 matches the time (step S108).

  If they do not match (N in step S108), the process proceeds to step S106, and the medical information is deleted.

  If they match, steps S107 to S108 are continued until a medical treatment start (medical treatment start instruction 501 in FIG. 5) is input from the input unit 28 (Y in step S109).

  When the medical treatment start is input from the input unit 28 (Y in step S109), the CPU 10 adds the medical treatment start time to the medical record and displays the medical record information on the display unit 27 (see the screen display example 600 in FIG. 6). At the same time, an input to the chart is accepted from the input unit 28 (step S110).

  In step S110, the CPU 10 further receives the GPS signal 6, acquires the current position of the portable terminal 2 based on this signal, and determines whether the current position and time of the portable terminal 2 match the schedule (step S111). ). If they match (Y in step S111), steps S110 to S111 are continued until the end of medical treatment (medical treatment end instruction 601 in FIG. 6) is input from the input unit 28 (Y in step S112).

  If they do not match (N in step S111), the process proceeds to step S106, and the medical information is deleted.

  When the end of medical care is input from the input unit 28 (Y in step S112), the CPU 10 adds the medical end time to the chart and transmits the record additional information to the server 3, and then stores the medical information of the first patient in the main memory 21. Then, it is deleted from the storage device 22 and the display memory 24 (step S113).

  Next, the CPU 10 determines whether or not all visits have been completed (step S114). If the visit has not been completed (N in step S114), the process of S102 to S113 is performed for the next patient, A series of processing is repeated until the end (step S114).

(1.4 Situation of portable terminal 2 when deletion processing is performed)
Here, the situation of the portable terminal 2 when the information deletion process is performed in step S106 and step S113 will be described.

(1.4.1 When N in Step S105)
N in step S105 is a case where the portable terminal 2 has not arrived at the patient's home and the current time exceeds the time limit. In such a case, for example, the following situation applies.
-The user forgot to carry the portable terminal 2 before leaving the medical facility-The portable terminal 2 was lost or stolen during the visit route

(1.4.2 N at Step S108 and N at Step S111)
N in step S108 and N in step S111 are cases where the current position and time of the portable terminal 2 do not match the schedule after arriving at the patient's home. In such a case, for example, The situation applies.
The position of the portable terminal 2 does not change because the user left the portable terminal 2 at or near the patient's home, left behind, or lost, but time has passed. After arrival at the patient's house, the portable terminal 2 is taken away. As a result, the position of the portable terminal 2 became inconsistent.

  In these situations, the portable terminal 2 leaves the user's hand and the user cannot manage the information. Therefore, as described above, the CPU 10 performs the information deletion process in step S106, so that no medical information exists in the portable terminal 2, so that a person other than the user operates the portable terminal 2 or displays the display unit. Even if 27 is viewed, medical information can be prevented from leaking.

  In addition, the situation where the schedule must be changed greatly, such as an accident after leaving the medical facility or a medical discontinuation due to a disaster, also applies to the case of N in step S105. In such a case, even if the user has the portable terminal 2, the information in the portable terminal 2 is not used for medical care, so it is preferable to delete the information for safety. . Therefore, in this embodiment, in such a case, the CPU 10 performs the information deletion process in step S106.

(1.4.3 Y from S112 to S113)
Y from step S112 to S113 is a situation in which the medical care at the patient's home has been completed and the information entered in the medical record has been transmitted to the server 3. Since the medical information of the patient who has completed the medical care is not used later, it is preferable to delete the information about the patient who has finished the medical care for safety. Therefore, in this embodiment, the CPU 10 performs the information deletion process even in such a case.

  As described above, information management is performed in the portable terminal 2 in consideration of various situations. In particular, when the portable terminal 2 leaves the user due to neglect, misplacement, loss, theft, etc., the information is deleted, and no medical information exists in the portable terminal 2, so the medical information Can be prevented in advance.

  In addition, since information that is not used is deleted in preparation for a trouble that may occur in the future, it is possible to provide the portable terminal 2 in which the security of medical information is technically guaranteed.

(1.5 Modification of this embodiment)
The present embodiment is not limited to the above-described one, and can be changed without departing from the spirit of the present embodiment.
In this embodiment, the case where the medical information of all the patients scheduled to be visited in step S101 is acquired from the server 3 has been described. However, the medical information of the corresponding patient may be acquired for each visit to the patient's home. In this case, since the medical information of the corresponding patient does not exist in the portable terminal 2 until it arrives at the patient's home (or its surroundings), it is necessary to prevent information from being leaked due to some trouble before that. Can do.

  In the present embodiment, the case where the mobile terminal 2 automatically sets the visit schedule has been described. However, the visit schedule may be set and changed by the user in consideration of the consultation time for each patient. . When the time required for medical treatment or movement is indefinite and often does not coincide with the schedule, the portable terminal 2 measures the elapsed time after the medical treatment start instruction is input by the user, and automatically when a predetermined time elapses For example, the schedule may be changed or reset during the medical treatment by extending the time. On the other hand, when the time required for medical treatment and movement is constant and it is certain that the time is consistent with the schedule, the portable terminal 2 does not set the visit schedule, and does not set the visit schedule from the outside such as the server 3 or an external storage device. You may make it acquire.

  Further, in step S107 and step S110, the determination as to whether the position and time of the portable terminal 2 coincide with the schedule is based on the elapsed time since the portable terminal 2 arrived at the patient's house, the scheduled stay time, The comparison may be performed. In this case, if the elapsed time is equal to or shorter than the stay time, the CPU 10 displays patient information and accepts entry into the medical chart. If the elapsed time exceeds the stay time, the CPU 10 deletes the medical information. The same applies to the time required to travel the visited route and the scheduled travel time.

  In step S113, the CPU 10 may display a transmission completion message as shown in FIG. After the medical information of the corresponding patient is deleted, the portable terminal 2 cannot display the patient information. However, after the user is authenticated, the mobile terminal 2 displays the medical information again from the server 3, for example. You may do it.

  In the present embodiment, various types of medical information are associated with each patient. However, not only medical information but also various types of information can be associated with each other and used as information management targets of the portable terminal 2. . For example, if a file folder is linked, all the files in it are subject to information management.

(1.6 Effects of this embodiment)
As described above, the portable terminal 2 of the present embodiment deletes information stored therein when the preset time and position do not match the actual time and position.

However, when the transmitter signal 72 is not received by the receiving unit 29 or when the ID cannot be acquired from the signal, the position information acquiring unit 12 sends information without ID to the information managing unit 14.

  If the ID of the transmitter 71 acquired by the medical information acquisition unit 11 and the ID of the transmitter 71 acquired by the position information acquisition unit 12 match, the information management unit 14 It is determined that the position matches the planned position. However, if the IDs do not match or the information from the position information acquisition unit 12 does not have an ID, it is determined that the current position of the portable terminal 2 does not match the planned position. That is, since the position match and mismatch are more accurately performed by the ID match / mismatch determination, leakage of medical information can be more reliably prevented.

(2.2 Flow of medical information management process)
Next, with reference to FIG. 8, operation | movement of the portable terminal 2 of this embodiment is demonstrated.
FIG. 8 is a flowchart for explaining the flow of medical information management processing executed by the portable terminal 2. The CPU 10 of the portable terminal 2 reads the program and data related to the medical information management process shown in FIG. 8 from the main memory 21, and executes the process based on the program and data.

  First, the CPU 10 of the portable terminal 2 acquires medical information such as visit information, patient information, and ID of the transmitter 71 stored in the storage device 4 via the server 3, and stores them in the main memory 21 and the storage device 22. Store (step S201).

  Next, the CPU 10 sets a visit schedule and a visit route based on the acquired visit destination information and displays them on the display unit 27 (see step S202, screen display example 400 in FIG. 4).

  Next, the CPU 10 determines whether or not the user has arrived at or near the patient's home by an input indicating that the user has arrived at the patient's home from the input unit 28 or other position specifying function (step S203). When the portable terminal 2 arrives at the patient's home (Y in step S203), the patient information is displayed on the display unit 27 (see the screen display example 500 in FIG. 5) and the transmitter signal 72 is received (see FIG. 5). Step S206).

  On the other hand, when the portable terminal 2 has not arrived at the patient's home (N in step S203), the process proceeds to step S204.

  If it is determined in step S204 that the current time is within a predetermined time limit such as an adjustment time in which a delay in visit is anticipated (Y in step S204), the CPU 10 returns to step S202 and resets the visit schedule. However, if the current time exceeds the time limit (N in Step S204), the CPU 10 deletes the medical information from the main memory 21, the storage device 22, and the display memory 24 (Step S205).

  From the transmitter signal 72 received in step S206, the CPU 10 acquires the ID of the transmitter 71, whether the scheduled time of the patient's home visit matches the current time of the portable terminal 2, and step S201. In step S207, it is determined whether the ID of the transmitter 71 acquired from the server 3 matches the ID acquired from the transmitter signal 72.

  If one does not match or both do not match (N in step S207), the process proceeds to step S205, and the medical information is deleted.

  If both match, steps S206 to S207 are continued until a medical treatment start (medical care start instruction 501 in FIG. 5) is input from the input unit 28 (Y in step S208).

  When the medical treatment start is input from the input unit 28 (Y in step S208), the CPU 10 adds the medical treatment start time to the medical chart and displays the medical chart information on the display unit 27 (see the screen display example 600 in FIG. 6). At the same time, an input to the chart is accepted from the input unit 28 (step S209).

  In step S209, the CPU 10 further receives the transmitter signal 72, obtains the ID of the transmitter 71 from this signal, and whether the scheduled time of the patient's home visit matches the current time of the portable terminal 2, and It is determined whether the ID of the transmitter 71 acquired from the server 3 in step S201 matches the ID acquired from the transmitter signal 72 (step S210).

  If one does not match or both do not match (N in step S210), the process proceeds to step S205, and the medical information is deleted.

  If both match, steps S209 to S210 are continued until the end of medical treatment (medical treatment end instruction 601 in FIG. 6) is input from the input unit 28 (Y in step S211).

  When the end of medical treatment is input from the input unit 28 (Y in step S211), the CPU 10 adds the medical treatment end time to the chart and transmits the record additional information to the server 3, and then stores the medical information of the first patient in the main memory 21. Then, it is deleted from the storage device 22 and the display memory 24 (step S212).

  Next, the CPU 10 determines whether or not all the visits have been completed (step S213). If the visit has not been completed (N in step S213), the process of S202 to S212 is performed for the next patient, A series of processing is repeated until the end (step S213).

(2.3 Status of portable terminal 2 when deletion processing is performed)
The situation of the portable terminal 2 when the information deletion process is performed in step S205 and step S212 is the same as the situation described in the first embodiment. In the present embodiment, when the distance between the vehicle 7 and the portable terminal 2 is several tens of meters or more, the transmitter signal 72 is not received by the receiving unit 29 and thus “no ID” is set. Also in this case, as in the first embodiment, it is determined that the current position of the portable terminal 2 does not match the planned position, and the CPU 10 performs the information deletion process in step S205.

(2.4 Modification of this embodiment)
The present embodiment is not limited to the above-described one, and can be changed without departing from the spirit of the present embodiment.
Moreover, although the case where the transmitter 71 mounted in the vehicle 7 was used was demonstrated in this embodiment, you may use what carried the transmitter 71 in carrying goods 73, such as a user's chest. Using such a carry-on item 73 with a transmitter 71 is convenient because the portable terminal 2 can manage information even in the height direction, such as when there are multiple patient houses on different floors in a high-rise building. .

  Further, the GPS signal 6 and the transmitter signal 72 may be used in combination. This combination is useful, for example, in an environment where the GPS signal 6 reaches around the patient's home but the patient's home is in a building where the GPS signal 6 does not reach and the transmitter signal 72 can be received.

(2.5 Effects of this embodiment)
As in the first embodiment, the portable terminal 2 of the present embodiment can be left unattended, misplaced, lost, stolen, etc. even in places where GPS signals cannot be used, such as in mountainous areas. In this case, since the information is deleted and no medical information exists in the portable terminal 2, it is possible to prevent the medical information from leaking.

  Further, in preparation for a trouble that may occur in the future, information that is not used by the user is also deleted, so that it is possible to provide the portable terminal 2 that technically guarantees the safety of medical information.

(2.6 Portable Terminal, Electronic Information Management Method, Program, and Electronic Information Management System in the Present Embodiment)
The portable terminal 2, the electronic information management method, the program, and the electronic information management system 1 according to the present embodiment have the same effects as those described in the first embodiment.

  Moreover, since the position information acquisition unit 12 in the portable terminal 2 of the present embodiment acquires the position of the portable terminal 2 based on the transmitter signal 72, a place where the GPS signal 6 cannot be used such as a mountainous area. However, as long as the transmitter signal 72 can be received, the portable terminal 2 operates assuming that the current position of the portable terminal 2 is as planned, and electronic information management is performed in the same manner as when the GPS signal 6 is used. It can be carried out.

  Further, the position information acquisition unit 12 acquires the ID of the transmitter 71 from the transmitter signal 72 transmitted from the transmitter 71, and the information management unit 14 does not match the time with the scheduled time. When the ID is different from the ID stored in the storage unit 22, the electronic information is deleted from the storage unit 22. Thereby, since the coincidence / mismatch of the position of the portable terminal 2 using the transmitter signal 72 is more accurately determined, it is possible to more reliably prevent the leakage of medical information.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these are naturally within the technical scope of the present invention.
