Abstract

PROBLEM TO BE SOLVED: To enable the confirmation of a patient state at the present time by a medical equipment (ME) image in addition to a patient state when an ME call has been generated.SOLUTION: When an ME call from medical equipment 2 is generated, a nurse call master unit 6 acquires an ME image from the medical equipment 2 and stores the image in an image server 11 as a call generation time ME image. Subsequently, when the acquisition request of the call generation time ME image is generated in an IP portable telephone 10, an ME image at that point of time is acquired from the medical equipment so as to be stored in the image server 11 as a history confirmation time ME image. Then, the call generation time ME image and the history confirmation time ME image are transmitted from the image server 11 to the IP portable telephone 10 and displayed. Consequently, a nurse who has not made a response due to busyness when the ME call has been generated can confirm the patient states at the time of ME call generation and the present time by the ME images in subsequently confirming the history of the ME call.

Description

  The present invention relates to a nurse call image display control system, and is particularly suitable for application to a nurse call system configured to notify a call from a nurse call slave unit to a nurse call master unit or a portable nurse call master unit. Is.

  In general, nurse call systems used in hospitals and nursing care facilities are used when patients and care recipients (hereinafter simply referred to as patients) need the support of doctors, nurses, and caregivers (hereinafter simply referred to as nurses). In addition, the system is configured such that a patient can call a nurse by pressing a call button or the like of a nurse call cordless handset.

  In many nurse call systems, a call is made to a nurse call master unit installed in a nurse center, but a call is made to a PHS (Personal Handyphone System) terminal carried by a nurse via a private branch exchange (PBX). A nurse call system is also provided. In recent years, a nurse call system that includes a SIP (Session Initiation Protocol) server and makes a call to an IP (Internet Protocol) telephone has also been proposed (see, for example, Patent Document 1).

  The nurse call system described in Patent Document 1 displays a nurse call cordless handset that makes a call and a call from a patient in a room, and calls from the nurse call cordless handset (call history such as call source, call destination, and call time). And a nurse call parent device that performs a response call and a portable nurse call parent device (IP phone). The nurse call base unit and the IP telephone are connected to each other by a SIP server that connects the extensions.

  There has also been proposed a WEB nurse call device that transmits a video captured by a camera to a nurse call parent device in addition to call information from a nurse call child device (see, for example, Patent Document 2). The WEB nurse call device described in Patent Document 2 includes a camera and a WEB adapter that transmits a video signal of the camera and call information from the nurse call cordless handset to the care facility. It has a nurse call master. In the nurse call parent device, the caller information indicated by the call information is read from the storage unit and displayed on the display together with the transmitted video signal.

  In the conventional nurse call system including these Patent Documents 1 and 2, a call notification to the nurse call parent device or the portable nurse call parent device is performed by ringing a ringing tone and displaying on a monitor screen. For example, when a call is made from a nurse call cordless handset, a ringing tone sounds at the nurse call master phone or portable nurse call master phone, and patient information such as the name and room number of the calling patient is displayed on the monitor screen. Is displayed. In addition to patient information, some systems are configured to display call types such as general call / emergency call / ME call. The ME call is a call that is performed when a patient's abnormality is detected in a medical device connected to the nurse call slave.

  The nurse call system displays the call type on the monitor screen of the nurse call master unit or portable nurse call master unit when a call is made from the nurse call slave unit. Therefore, it is possible to take an appropriate response such as a quick response to a call with a high degree of urgency. However, in the conventional nurse call system, when an ME call occurs, the nurse can grasp the ME call by looking at the display of the call type, but what kind of abnormality occurs in the measurement result of the medical device. There was a problem that it was not possible to grasp whether it was.

  In response to such a problem, the present applicant has filed a patent application regarding a technique that enables notification of what abnormality has occurred in the measurement result of a medical device when an ME call occurs (patent) Reference 3). In the system described in Patent Document 3, when an ME call from a medical device occurs, an ME image indicating a measurement result is acquired from the medical device and stored in a predetermined location of the storage device. Then, after receiving a call signal in at least one of the nurse call parent device and the portable nurse call parent device, when an operation for response is detected, a predetermined location is accessed, and the ME stored in the storage device The image is acquired and displayed.

  By the way, when a call is made to the portable nurse call parent device, it is generally performed to record the call history in the portable nurse call parent device. Therefore, in the system described in Patent Document 3, the ME image stored in the image server when the ME call is made is associated with the call history recorded in the portable nurse call parent device. The ME image stored when the ME call is made can be acquired and displayed by the portable nurse call from the image server when the call history is confirmed later.

  However, although the ME image when the ME call is performed can be displayed on the portable nurse call parent device, the ME image at the time when the call history is confirmed cannot be acquired and displayed. Therefore, a nurse who has not released his / her hand at the time of ME call occurrence can confirm the ME image at the time of ME call occurrence, but the state of the patient at the present time is an ME image. There was a problem that could not be confirmed by.

  The present invention has been made to solve such a problem, and a nurse who confirms the history of ME calls has added the patient status at the present time in addition to the patient status at the time of ME call occurrence. It is an object of the present invention to make it possible to confirm the state of a state with an ME image.

  In order to solve the above-described problem, in the present invention, when an ME call from a medical device occurs, an ME image indicating a measurement result is acquired from the medical device, and the image is displayed as a call occurrence ME image together with the first image ID. Store it on the server. In addition, when an ME image acquisition request is generated at the time of call occurrence in the portable nurse call master unit, an image acquisition request including identification information of the nurse call slave unit included in the call history information is generated, and the nurse call child is generated. The ME image indicating the measurement result is acquired from the medical device corresponding to the machine identification information, and stored in the image server as the history check time ME image together with the second image ID. Then, a call occurrence ME image corresponding to the first image ID and a history confirmation ME image corresponding to the second image ID are transmitted from the image server to the portable nurse call parent device that has transmitted the image acquisition request. And display it.

  According to the present invention configured as described above, when a ME call occurs, the ME image at the time of the call occurrence is stored in the image server, and then the ME image at the time of the call occurrence is obtained from the portable nurse call parent device to the image server. When the request is transmitted, a new image acquisition request is generated at the same time, and a history check ME image indicating the current measurement result is acquired from the medical device and stored in the image server. Then, the ME image at the time of the call occurrence stored in the image server at the time of the ME call occurrence and the ME image at the time of history confirmation newly stored in the image server at the time of the acquisition request of the ME image at the time of the call occurrence are obtained. It will be sent to the requesting nurse call master and displayed. As a result, for example, when a nurse who has not released his / her hand at the time of ME call occurrence and has not confirmed the response of the ME call thereafter, in addition to the patient state at the time of ME call occurrence, It becomes possible to check the state of the image by the ME image.

Further, the call history recording unit 201 of the IP mobile phone 10 records the call history information including the first image ID and the nurse call slave identification information in the internal memory 202 (step S13). Although not shown in the flowchart of FIG. 3, the nurse who has received the call can respond to the ME call by off-hooking the IP mobile phone 10. Thus, the process of the flowchart shown in FIG. 3 when the ME call occurs is completed.

  FIG. 4 is a flowchart showing an operation example of the image display control system when acquiring the ME image using the call history information recorded in the IP mobile phone 10 as described above. Here, the controller 5, the IP adapter 7, and the SIP server 8 simply transfer signals, and are not shown. Note that the processing of the flowchart shown in FIG. 4 starts when the operation receiving unit 203 receives an operation for acquiring an ME image using the call history information.

  First, the first image acquisition request transmission unit 204 of the IP mobile phone 10 includes the call history information when the operation reception unit 203 receives an operation for acquiring the ME image using the call history information. The first image acquisition request including the first image ID to be transmitted is transmitted to the image server 11 (step S21). The first image acquisition request transmission unit 204 sends an image acquisition request including identification information of the nurse call slave unit included in the call history information via the SIP server 8, the IP adapter 7 and the controller 5. It transmits to the machine 6 (step S22).

  In the image server 11, when the first image acquisition request reception unit 306 receives the first image acquisition request transmitted from the IP mobile phone 10 in step S21, the first image acquisition request is received by the image display control unit 303. Notify Receiving this notification, the image display control unit 303 reads the call occurrence ME image corresponding to the first image ID included in the first image acquisition request from the first location storage unit 301 (step S23). . Then, the image display control unit 303 transmits the ME image at the time of calling read out from the first location storage unit 301 to the IP mobile phone 10 that transmitted the first image acquisition request (step S24).

  On the other hand, when the nurse call parent device 6 receives the image acquisition request transmitted from the first image acquisition request transmitting unit 204 of the IP mobile phone 10 at the image acquisition request receiving unit 106, the nurse call parent device 6 receives the image acquisition request. The ME image acquisition unit 104 and the image ID notification unit 105 are notified.

  Upon receiving this notification, the second ME image acquisition unit 104 responds to the identification information of the nurse call slave included in the image acquisition request via the controller 5, the corridor lamp 4, and the wall-embedded slave 3. An image acquisition command is transmitted to the medical device 2 to be acquired, a history confirmation ME image indicating the measurement result is acquired from the medical device 2, and a unique second image ID is assigned thereto (step S25).

  Then, the second ME image acquisition unit 104 supplies the history check time ME image acquired from the medical device 2 and the second image ID to the image server 11 (step S26). The second ME image storage unit 305 of the image server 11 stores the history confirmation time ME image supplied from the nurse call parent device 6 in the second location storage unit 302 together with the second image ID (step S27).

  The image ID notification unit 105 that has received the notification of the image acquisition request from the image acquisition request receiving unit 106 uses the second image ID notified from the second ME image acquisition unit 104 as the controller 5, the IP adapter 7, and The data is transmitted to the IP mobile phone 10 via the SIP server 8 (step S28).

  When the IP mobile phone 10 receives the second image ID transmitted from the image ID notification unit 105 of the nurse call parent device 6, the second image acquisition request transmission unit 205 includes the second image ID. A second image acquisition request is transmitted to the image server 11 (step S29).

  In the image server 11, when the second image acquisition request receiving unit 307 receives the second image acquisition request transmitted from the IP mobile phone 10, the image server 11 notifies the image display control unit 303 of the second image acquisition request. . Receiving this notification, the image display control unit 303 reads the call occurrence ME image corresponding to the second image ID included in the second image acquisition request from the second location storage unit 302 (step S30). .

  After that, the image display control unit 303 transmits the history confirmation ME image read from the second location storage unit 302 to the IP mobile phone 10 that transmitted the second image acquisition request (step S31). The display control unit 206 of the IP mobile phone 10 displays the ME image at the time of call occurrence transmitted from the image server 11 at step S24 and the ME image at the time of history confirmation transmitted at step S31 on the monitor screen (step S32). ). Thereby, the process of the flowchart shown in FIG. 4 is completed.

  As described above in detail, in this embodiment, when an ME call from the medical device 2 occurs, an ME image indicating the measurement result is acquired from the medical device 2 and stored in the image server 11 as the ME image at the time of the call occurrence. . Further, when a first image acquisition request for acquiring a ME image at the time of call occurrence using the call history information in the IP mobile phone 10 is generated, the identification information of the nurse call slave unit included in the call history information Is generated, a ME image indicating a measurement result is acquired from the medical device 2 corresponding to the identification information of the nurse call slave unit, and stored in the image server 11 as a history check ME image. Then, for the IP mobile phone 10 that has transmitted the image acquisition request, the ME server at the time of calling and the ME image at the time of history confirmation are transmitted from the image server 11 and displayed.

  According to the present embodiment configured as described above, after a call occurrence ME image is stored in the image server 11 when an ME call occurs, the IP mobile phone 10 acquires the call occurrence ME image from the IP mobile phone 10 to the image server 11. When the request is transmitted, a new image acquisition request is generated at the same time, and a history check ME image indicating the current measurement result is acquired from the medical device 2 and stored in the image server 11. Then, a call occurrence ME image stored in the image server 11 when the ME call occurs, and a current history confirmation ME image stored in the image server 11 newly when the call occurrence request for the ME image is requested. It is transmitted to the IP mobile phone 10 that is the image acquisition request source and displayed.

  As a result, for example, when a nurse who has not released his / her hand when the ME call is generated and has not been able to respond, confirms the history of the ME call on the IP mobile phone 10, the state of the patient at the time of the ME call is displayed. In addition, the state of the patient at the present time can be confirmed by the ME image.

  In the above-described embodiment, the IP mobile phone 10 accesses the image server 11 in two steps: when the call occurrence occurs from the image server 11 and when the history confirmation ME image is obtained. Although an example has been described, the present invention is not limited to this. For example, the IP mobile terminal 10 accesses the image server 11 only once when the first image acquisition request is transmitted, and the second ME image acquisition unit 104 acquires the history check ME image from the medical device 2. Then, the ME image at the time of calling and the ME image at the time of history confirmation may be collectively transmitted from the image server 11 to the IP portable terminal 10.

  In the above embodiment, when an ME call occurs, only the ME image at the time of the call occurrence is acquired from the medical device 2 and stored in the image server 11. When the teacher off-hooks the IP mobile phone 10, the ME image at the time of call occurrence acquired from the medical device 2 may be transmitted from the image server 11 to the IP mobile phone 10 and displayed.

  In this case, when the IP mobile phone 10 receives a call signal from the SIP server 8, it detects whether or not the nurse has been off-hook in response to the ringing of the ringing tone. Access the server 11. Then, the IP mobile phone 10 uses the first image ID to acquire the call occurrence ME image stored in the first location storage unit 301 of the image server 11, and uses the obtained call occurrence ME image. Display on the monitor screen.

  Moreover, although the said embodiment demonstrated the example which displays the ME image at the time of a call generation, and the ME image at the time of log | history confirmation with the IP mobile telephone 10, this invention is not limited to this. For example, in addition to or instead of the IP mobile phone 10, the nurse call parent device 6 may display a ME image at the time of call occurrence and a ME image at the time of history confirmation. In this case, the ME image acquired from the medical device 2 may be stored in a memory (not shown) of the nurse call parent device 6 and the ME image may be acquired by accessing the memory.

  In the above-described embodiment, the example in which the nurse call parent device 6 includes the functions of the call type determination unit 101, the first ME image acquisition unit 103, and the second ME image acquisition unit 104 has been described. It is not limited to. For example, the controller 5 may be provided with these functions, or the IP adapter 7 may be provided.

  When the controller 5 has these functions, the controller 5 determines whether or not the call type is an ME call. If the controller 5 determines that the call is an ME call, the controller 5 acquires an image from the medical device 2. Send instructions. Then, as a response, the ME image at the time of calling sent from the medical device 2 is acquired by the controller 5 and supplied to the image server 11 via the nurse call parent device 6.

  In addition, even when an image acquisition request is sent from the IP mobile phone 10 to the controller 5, the controller 5 transmits an image acquisition command to the medical device 2. Then, the history confirmation time ME image sent from the medical device 2 as a response is acquired by the controller 5 and supplied to the image server 11 via the nurse call parent device 6.

  Moreover, although the said embodiment demonstrated the example using the IP mobile telephone 10 as an example of a portable nurse call main | base station, you may use a PHS terminal instead of the IP mobile telephone 10. FIG. In this case, for example, instead of the SIP server 8, a hand-held squall main device and a private branch exchange (PBX) are used. A PBX adapter is used instead of the IP adapter 7.

  In addition, each of the above-described embodiments is merely an example of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
