As shown in FIG. 2, the controller 4 includes a child device / camera table storage unit 41 that associates the child device 1 with the nursing camera 6, a patient / child device table storage unit 42 that associates the patient with the child device 1, A slave unit group storage unit 43 that groups the units 1, a controller CPU 44 that controls the controller 4, a controller IF 45 for connecting to the LAN 10, and the like are provided.

  In the ward, an area composed of a plurality of hospital rooms managed for each nurse station is set. That is, a group of slave units 1 that transmit a call signal to each master unit 3 is set, and the control unit 4 stores a management room for each master unit 3 in the slave unit group storage unit 43. In addition, the patient, the child device 1, and the nursing camera 6 are managed by IDs, and are associated by ID information.

  The server 5 includes a video storage unit 51 having a capacity equivalent to or larger than that of the second storage unit 33 of the PC master device 3b. The video storage unit 51 stores video recorded by the master unit 3 by operating the staff call button 12, and the video data stored in the video storage unit 51 is set so that it cannot be erased by operating the base unit 3. Has been.

The operation of the nurse call system configured as described above is as follows. However, the video storage operation of the nursing camera 6 will be mainly described.
First, the case where the patient calls the call grip button 1a to make a call will be described. When the call grip button 1 a is operated, a call signal is transmitted from the slave unit 1 to the controller 4 via the corridor lamp 2. Upon receiving this call signal, the controller 4 reads the parent device 3 set as the call destination by the controller CPU 44 from the child device group storage unit 43 and transmits the call signal. At the same time, based on the child device ID information included in the calling signal, the nursing camera 6 associated with the called child device 1 is identified with reference to the child device / camera table storage unit 41, that is, near the patient. The nursing camera 6 installed in is identified and activated, and a captured image is obtained. The video data obtained in this way is transmitted to the callee base unit 3.

Receiving the calling signal and the video data, base unit 3 rings the ringing tone and displays the video on display 32. Furthermore, recording is started in the first storage unit 33.
In this way, when the master device 3 performs a response operation by the nurse who has recognized the call, the nurse can talk with the patient while watching the patient video. Thereafter, when the call is finished, the imaging of the nursing camera 6 is stopped and the recording is also finished.

  When the call ends, the controller CPU 44 recognizes it, obtains the video data recorded in the first storage unit 33, temporarily stores it in its own storage unit (not shown), and then all the PC master units 3b in the system. , 3b... Starts transmission. At this time, the controller CPU 44 transmits video data to all the PC master units 3b, 3b,... Including the PC master unit 3b of the master unit 3 that has received the video from the nursing camera 6.

The PC master device 3 b that has received the video data from the controller 4 stores the video data in the second storage unit 34. In storing the video data, information such as a camera ID, a nurse call slave ID associated with the camera, and a patient ID are also stored as attached information.
On the other hand, when the storage in the second storage unit 34 is completed, the controller CPU 44 deletes the video stored in the first storage unit 33. The video stored in the second storage unit 34 in this way can be confirmed by being displayed on the display 35 by operating the PC master unit 3b.

Thus, the video transmitted from the nursing camera 6 is limited to one master unit 3, but the video is diffused and stored by all the master units 3, 3,. The image transmitted from the nursing camera 6 to the parent device 3 can be confirmed on any parent device 3. In addition, since there is no need to access and display the other base unit 3, it is possible to check the video with a simple operation. Therefore, when confirming the recorded video, it is not necessary to go to the parent device 3 to which the nursing camera 6 has transmitted the captured video, and the burden on the nurse can be reduced.
Further, while the nursing camera 6 is activated, the video is stored only in the first storage unit 33 of the parent device 3 that is receiving the video. For example, while the nurse is talking to the patient while watching the video. Can prevent a situation in which the traffic on the transmission line is congested and the call becomes unstable.
Furthermore, since the first storage unit 33 of the base unit 3 is deleted after the video is diffused and stored, an overflow situation can be prevented even if the storage capacity is small.
Further, since the video is stored in the personal computer, it is not necessary to greatly change the configuration of the desktop base unit 3a having a calling function from the configuration of the conventional desktop base unit, and the personal computer can be realized at low cost. Since the stored video can be confirmed by directly operating the second parent device 3b, it can be viewed smoothly.

Next, a case where the staff call button 12 is operated will be described. The staff call button 12 is operated when a nurse treating a patient requests support or the like.
When the staff call button 12 is pressed, a call signal is transmitted to the control unit 4 through the corridor lamp in the same manner as the operation of the call grip button 1a, and the control unit 4 is sent to the base unit 3 associated with the slave unit 1. Send a ringing signal. At the same time, the nursing camera 6 associated with the child device 1 is identified and activated based on the child device ID information included in the calling signal, and a captured image is obtained. The video data obtained in this way is transmitted to the callee base unit 3.

  Receiving the calling signal and the video data, base unit 3 rings the ringing tone, displays the video on display 32, and starts recording in first storage unit 33. When the nurse responds to this call, he / she can talk while watching the patient video. Thereafter, when the call is finished, the imaging of the nursing camera 6 is stopped and the recording is also finished.

  Thereafter, the controller CPU 44, which has recognized the end of the call, obtains the video recorded in the first storage unit 33, temporarily stores it in the storage unit (not shown), and then transmits it to the server 5 for storage control in the video storage unit 51. To do. In storing the video data, information such as a camera ID, a nurse call slave ID associated with the camera, and a patient ID are also stored as attached information.

  When the transfer of the video data to the server 5 is completed, the controller CPU 44 deletes the video stored in the first storage unit 33. The video stored in the server 5 in this way can be confirmed by being displayed on the display 35 by operating the arbitrary PC master unit 3b.

  As described above, since the video based on the operation of the staff call button 12 having a high importance level is stored in the server 5, it is difficult to cause a situation where the video is accidentally deleted, and the server 5 is deleted as described above. It may be set to be impossible, and the problem of erasing important video can be eliminated, and video management is easy.

In the above embodiment, the controller CPU 44 performs the diffusion storage control of the recorded video with the end of the call as a trigger. However, the control CPU 44 may execute it at a predetermined timing without matching the end of the call. For example, it may be performed every fixed time, or may be performed when a certain amount of video is accumulated in the first storage unit 33.
Further, although the storage destination of the video is changed by the operation of the call grip button 1a and the operation of the staff call button 12, the storage destination may be the same in both cases. In this case, all the videos may be stored in both the PC base unit 3b and the server 5, or only the PC base unit 3b may be stored and not stored in the server 5.
Further, when the nurse operates the parent device 3 to activate the nursing camera 6 and displays a captured image on the display 32, the same control as when the call grip button 1a is operated can be performed. Are stored in all the PC master units 3b, 3b,.
