A call between a nurse in the room and a patient in the room is established.

  At the time of calling, if the internet camera 30 is installed near the patient's bed, the internet camera 30 is activated to display the state of the patient. It is transmitted to the PC nurse call 31 of the nurse call parent device 3 via L9 → HUB50 → LAN cable L8. The PC nurse call 31 displays the video together with the above-described patient management data and medical nursing data.

  The internet camera 30 may be installed in a common part such as a corridor, lobby, reception, etc. For example, the internet camera 30 is activated when a human sensor (not shown) is activated or is always activated. In this manner, the state may be confirmed by the nurse call parent device 3 or the management personal computer 6.

  Next, a processing procedure in the case of changing the contents of each database in the management personal computer 6 that collectively manages the contents of the databases stored in the plurality of nurse call master units 3 is shown in the flowchart shown in FIG. This will be explained based on.

  In order to rewrite the database of a specific nurse call master unit 3, in order for a specific nurse or the like to access the nurse call master unit 3, first, a user password is input on the management personal computer 6 (step 101). . This password information signal is received by the PC nurse call 31 of the corresponding nurse call base unit 3 via the LAN cable L3 → HUB5 → LAN cable L4 → HUB5 → LAN cable L3. The PC nurse call 31 collates the password included in the information signal with the user information for authenticating whether or not access from the management personal computer 6 is permitted (step 102). To permit access to the database (steps 103 and 104). If the user information does not match, access to the database of the PC nurse call 31 is denied (steps 103 and 105).

  When access to the database of the storage unit 31a of the PC nurse call 31 is permitted, the specific nurse or the like refers to the contents of the database and inputs the contents to be changed by the management personal computer 6 to specify the specific contents. This is transmitted to the nurse call parent device 3 (steps 106 and 107). The PC nurse call 31 of the specific nurse call base unit 3 rewrites the contents of the database according to the received information signal of the changed contents, and returns the information signal of the rewritten contents (steps 108 and 109).

  In the management personal computer 13, based on the received information signal of the rewritten content, the change history, information on the changed nurse, etc., information specifying the changed database, information specifying the changed database, database change location, change content Is saved as a change log (step 110).

  In the modified nurse call master unit 3, the database after the change is used for the subsequent operations. When a call is made from the nurse call slave unit 1, the patient management data of the corresponding patient is compared with the database after the change. The contents of the medical nursing data are displayed on the display device of the PC nurse call 31. The password may be set for each nurse call parent device 3 or may be set as a password common to all nurse call parent devices 3.

  As described above, even if a plurality of nurse call master devices 3 are installed, the database of each nurse call master device 3 can be collectively managed by a single management personal computer 6, and the change history of various information Can be stored in the storage unit 61a of the management personal computer 6, so that it is possible to instantly know when and who changed what.

  In addition, since the nurse call master unit 3 and the management personal computer 6 are connected by the LAN cables L3 and L4, when the management personal computer 6 rewrites the database of the nurse call master unit 3, communication is performed. It can be performed by high-speed LAN communication.

  In the nurse call system described above, the patient management data and medical care data of the patient in charge are stored in the storage unit 31a of the PC nurse call 31 of the nurse call master unit 3 as a database. As shown, the nurse call parent device 3 may have the nurse call server 40 not own the database. That is, each database of the patient management data and medical care data managed by each nurse call parent device 3 is stored in one of the nurse call servers 40 and read from the nurse call server 40 by the nurse call parent device 3. To. As a result, each database of the plurality of nurse call parent devices 3 can be stored in one nurse call server 40, so that only one license for using the database software is required. Therefore, cost reduction can be achieved.

In this nurse call system, the standby screen for each nurse call parent device 3 is read from the nurse call server 40 and displayed when the system is in operation, at the time of system reset, or by a predetermined operation.

  When a patient in any hospital room calls using the hand button 12 or the hand slave 13 of the nurse call cordless handset 1, the call signal is sent from the plate cordless handset 11 to the corridor lamp connecting trunk L1 via the corridor lamp 2. It is transmitted and received by the controller 4. The call signal received by the controller 4 is received by the nurse call call unit 32 of the nurse call parent device 3 called via the communication cable L5, and the nurse call call unit 32 notifies that the call has been made. When a nurse or the like who has confirmed the notification responds with the nurse call communication unit 32 notified, a communication path is formed between the nurse call communication unit 32 of the nurse call master unit 3 and the nurse call slave unit 1 that has made the call. Then, a call between the nurse in the nurse station and the patient in the hospital room is established. In addition, the PC nurse call 31 of the called nurse call base unit 3 sends an information signal informing that there is a call to the nurse call server 40 via the LAN cable L3 → HUB5 → LAN cable L4 → HUB51 → LAN cable L10. Send. The nurse call server 40 refers to the contents of the database based on the information signal, reads the contents of the patient management data and medical care data of the patient who made the corresponding call, and the nurse call master 3 that has been called the information signal. Reply to PC nurse call 31. The information signal is transmitted to the PC nurse call 31 of the nurse call master 3 called via the LAN cable L10 → HUB51 → LAN cable L4 → HUB5 → LAN cable L3. The display device of the PC nurse call 31 displays the contents of the patient management data and medical care data of the patient who made the transmitted call. Further, when a nurse or the like who has confirmed the call from the patient at the Handinance 20 answers the call at the Handinance 20, a call path is formed between the Handinance 20 and the nurse call handset 1 that has called, and the circuit is in circulation. A call between a nurse in the hospital and a patient in the hospital room is established.

  On the other hand, nurses in the nurse station, visiting nurses, etc. can call a specific patient in the hospital room by calling the nurse call calling unit 32 of the nurse call master unit 3 in the nurse station or by using the hand dinance 20. To call. When a call is made from the nurse call communication unit 32 or the hand dinance 20, a call signal is received by the controller 4 and transmitted to the communication cable L1. The corridor lamp 2 to which the called nurse call handset 1 for the patient is connected receives the call signal and transmits it to the nurse call handset 1. The nurse call handset 1 informs that there has been a call from the plate handset 11 or the hand handset 13 and also forms a communication path with the nurse call base set 3 that has called the call. A call between a nurse in the room and a patient in the room is established.

  When the internet camera 30 is installed near the patient's bed at the time of calling, the internet camera 30 is activated to display the state of the patient, and this video is a video signal of a moving image or a still image and the LAN cable L9. → HUB 50 → Transmitted to PC nurse call 31 of nurse call base unit 3 via LAN cable L8. The PC nurse call 31 displays the video together with the above-described patient management data and medical nursing data.

  The internet camera 30 may be installed in a common part such as a corridor, lobby, reception, etc. For example, the internet camera 30 is activated when a human sensor (not shown) is activated or is always activated. In this manner, the state may be confirmed on the display device 90 connected to the nurse call parent device 3 or the nurse call server 40 by the monitor switch 80.

  Next, a processing procedure when the contents of each database are changed by the management personal computer 6 that collectively manages the contents of the database stored in the nurse call server 40 will be described with reference to the flowchart shown in FIG. .

  In order to rewrite the database of the nurse call server 40 corresponding to a specific nurse call parent device 3, in order for a specific nurse or the like to access the nurse call server 40, first, a password is entered on the management personal computer 6 (Step 201). This password information signal is received by the nurse call server 40 via the LAN cable L3 → HUB5 → LAN cable L4 → HUB51 → LAN cable L10. The nurse call server 40 collates the password, ID code, etc. included in the information signal with the user information for authenticating whether or not access from the management personal computer 6 is permitted (step 202). Then, the authentication OK is returned, and access to the database is permitted (steps 203 and 204). If the user information does not match, access to the database of the nurse call server 40 is denied (steps 203 and 205).

  When access to the database of the nurse call server 40 is permitted, the specific nurse or the like refers to the contents of the database, inputs the contents to be changed with the management personal computer 6, and sends the contents to the nurse call server 40. (Steps 206 and 207). The nurse call server 40 rewrites the content of the database for the corresponding nurse call master unit according to the received information signal of the changed content, and returns the rewritten content information signal (steps 208 and 209).

  In the management personal computer 6, based on the received information signal of the rewritten content, the change history, information such as the changed nurse, information specifying the changed database, the changed database location, the changed content Is stored as a change log (step 210).

  In the modified nurse call server 40, the database after the change is used for the subsequent operations. When a call is made from the nurse call handset 1, the patient management data of the corresponding patient is compared with the database after the change, The contents of the medical nursing data are displayed on the display device 90.

  In the case where the backup server 70 is provided so that the operation as the nurse call system can be performed even if the database stored in the nurse call server 40 is damaged, Since the latest data is transferred via the LAN cable L11, the backup server 70 can be used. In this case, the monitor switch 80 switches the display device 90 connected to the nurse call server 40 side to the backup server 70 side so that the contents of the database of the backup server 70 can be displayed. As a result, the subsequent operation can be performed without any trouble, and the main nurse call server 40 can be restored during this time.
