The nurse call system configured as described above operates as follows. However, since the call using the slave unit 1 and the response using the master unit 3 or the portable terminal 5 are the same as those in the prior art, the description is omitted, and here the case where the medical device 9 is connected to the slave unit 1 The explanation will focus on the operation of, especially the management of usage time.
When the medical device 9 is connected to the connection terminal 12 of the plate slave unit 1b, the connection device detection unit 13 recognizes the connection from the change in the resistance value of the connection terminal 12, and the resistance value of the plug of the connected medical device 9 further. To determine the type of the medical device 9 (such as an artificial respirator or a drip device). The slave CPU 14 generates a connection signal including the type information of the medical device 9 thus determined by the connected device detection unit 13 and transmits the generated connection signal to the corridor light 2.

  In the corridor light 2 which has received the connection signal, the ID information (bed number information) of the transmission source child device 1 set in advance is attached to the connection signal and transmitted to the parent device 3.

  In the main unit 3 that has received the connection signal from the hallway light 2, the main unit CPU 41 recognizes it and performs the following control. The slave device ID and the medical device type information are read from the connection signal, and the patient related information storage unit 35 is referenced to read the patient associated with the slave device ID, that is, the bed number. Furthermore, the time at that time is read from the internal clock of the parent device CPU 41 and is used as the usage start time. The type information of the medical device 9 thus read, the bed number information, and the use start time information are linked to the name information of the patient using the medical device 9 and stored in the medical device information storage unit 36.

Also, after storing the usage start time, base unit CPU 41 starts counting the usage time from that time, and changes the color of the frame of the patient in the bed to which medical device 9 in the patient information displayed in a list is connected. Thus, the fact that the medical device 9 is connected can be recognized from the list display.
FIG. 4 is an explanatory view showing the display of the first display 31 in the standby state, and the patient information list is displayed on the first display 31 in bed units as shown in FIG. In FIG. 4, P is a patient frame where individual patient information is displayed in a frame corresponding to a bed. In the patient frame P, a patient's name display portion P1, a bed number display portion P2, a notification light P3 for notifying a call, and the like are provided. Also, Q is a room number display frame.

In this display state, FIG. 5 shows a state in which the medical device 9 is connected to the child device 1, and shows a state in which the color of the patient frame P using the medical device 9 has changed.
As described above, the change in color of the patient frame P makes it possible to grasp the patient using the medical device 9 in a state where the patient information list is displayed, and it is easy to grasp the location of the medical device 9 in use. Easy to manage.

  In addition to changing the color of the patient frame P, the display of the bed (or patient) to which the medical device 9 is connected may change the color inside the patient frame P. You may change the color of the surroundings.

  Further, the connection time information of the medical device 9 can be confirmed by pop-up display on the first display 31 by a predetermined display operation of the operation unit 34. FIG. 6 shows a state in which the connection time of the medical device is displayed in a pop-up manner, in which R1 is a pop-up display frame. By the predetermined operation of displaying the detailed information of the specific patient, the patient detailed information including the usage time of the medical device 9 is popped up as shown in FIG. In FIG. 6, the display "option connection time" indicated by P4 is the use time display section.

Thereafter, when the use of the medical device 9 is finished, the plug is removed to move the medical device. When the plug is pulled out, the connected device detection unit 13 detects it and notifies it to the slave CPU 14, and the slave CPU 14 generates a removal signal, and the main phone 3 is sent via the corridor light 2 similarly to the connection signal. Will be sent.
In the base unit 3 receiving the removal signal, the base unit CPU 41 ends the counting of the usage time, and at the same time a predetermined use end operation described later is not performed, so the plug falls off or disconnection occurs and the removal signal Is determined to have been transmitted, and an alarm sound is issued from the speaker of the communication unit 38. The alarm sound is stopped by a predetermined stop operation of the parent device 3.

The notification of this alarm sound can eliminate the notification itself by performing a predetermined operation end operation before removing the plug, and the plug can be removed with ease.
Specifically, a target patient is selected from the operation unit 34 of the parent device 3, a detail screen is displayed, and a "medical device removal" button (not shown) is touched. By this operation, the parent device CPU 41 determines that the use of the medical device 9 has ended, and ends the counting of the use time. As a result, time data (cumulative use time data) in which the use time is determined and counted is linked to the patient's name using the medical device 9 and stored in the medical device information storage unit 36.
Then, the removal signal is continuously transmitted to the base unit 3 by removing the plug from the connection terminal 12, but the base unit CPU 41 carries out a new operation such as an alarm sound or the like when the use end operation is performed. do not do.

Thus, in response to the connection signal of the medical device 9, the parent device 3 starts counting the usage time, receives the removal signal, ends the count, and stores the data, which the patient uses. The usage time of the medical device 9 can be grasped without counting up, and management of the usage state and the usage result of the medical device 9 is facilitated.
Also, when the connection to the connection terminal 12 of the medical device 9 is disconnected, an alarm sound is emitted by the parent device 3, but the alarm sound is generated even if the medical device 9 is removed by using the parent device 3 before the plug is removed. There is no need to be alerted, and there is no need for the troublesome operation of stopping the alarm after removing it.
Furthermore, since the counting of the medical device use time is ended in response to the use end operation, highly accurate management of the medical device use time can be performed.
Further, in addition to the usage time of the medical device 9, the type of the medical device 9 and the patient using it can be simultaneously grasped in the parent device 3, so detailed management can be performed.

  Next, a flow of change control of the use time of the medical device 9 when the bed movement in which the location of the patient using the medical device 9 is changed is performed will be described. When moving a patient to another bed, first, a bed moving operation is performed in the main unit 3. The bed moving operation is performed by operating the operation unit 34 and displaying a bed moving screen as pop-up on the first display 31. FIG. 7 shows the display of the first display 31 on which this operation screen is displayed, and R2 is a bed movement screen on which a pop-up display is shown, and shows a case where the patients are replaced with each other. When one patient is moved to an empty bed, one patient's name is blank.

In response to the bed moving operation, when the moving patient first uses the medical device 9, the parent device CPU 41 determines that the use end operation is performed, and calculates and stores the accumulated use time together with the end time. Then, when the bed number of the destination is changed, the bed number linked to the patient is changed and stored.
Also, the medical device 9 is removed from the handset 1 for movement in accordance with the movement of the patient, and even if the removal signal is received, it is ignored and an alarm sound is not issued.

  After that, when the medical device 9 is connected to the slave unit 1 of the movement destination bed, the use start time is registered in the same flow as described above, and the count of the use time is restarted. After that, when the use ends and the medical device is removed, the usage time after restart is added to the cumulative usage time linked to the patient until then, and the new cumulative usage time is calculated and stored. Ru.

  Then, the usage time data for each medical device stored in the medical device information storage unit 36 is called by the parent device 3 or the management PC 10 and displayed on the first display 31 or the display 10 a of the management device 10. The usage history for each medical device is displayed in a list (not shown) together with the connection start time, the connection end time, and the cumulative use time, and the use status can be easily confirmed.

As described above, since the counting of the medical device use time is ended by the bed moving operation, it is possible to manage the use time with high accuracy. In addition, even if the medical device 9 is removed for movement, no alarm sound is generated, so there is no need to perform a separate use end operation.
In addition, even if the bed number of the patient is changed due to the bed movement, the usage time data of the medical device 9 is linked to the patient and stored, so it is continuously counted for the same patient and the bed movement is There is no need to perform troublesome counting operations due to the occurrence, counting of the usage time of the medical device 9 is not applied to different patients, and the burden on the nurse can be reduced.

In the above embodiment, while the patient information list is displayed in bed units, the color of the patient frame P can be changed to confirm the location where the medical device 9 is used, but the number of beds is small. If the patient frame P is relatively large, the type and use time of the medical device 9 may be displayed in the patient frame P.
Although the patient related information storage unit 35, the medical device information storage unit 36, and the call history information storage unit 37 are provided in the base unit 3, any or all of the storage units may be provided in the controller 4.
Furthermore, although the usage time and type data of the medical device 9 are linked to the patient and managed, they may be linked and managed not to the patient but to the bed number, and can be managed similarly.
