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 thereof will be omitted. Here, when the medical device 9 is connected to the slave unit 1 The operation will be described mainly with respect to the management of the 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 further the resistance value of the plug of the connected medical device 9 Is detected to determine the type of the medical device 9 (such as a ventilator or an infusion device). The slave CPU 14 generates a connection signal including the type information of the medical device 9 determined by the connected device detection unit 13 in this way, and transmits the connection signal to the corridor lamp 2.

  In the corridor lamp 2 that has received this connection signal, 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 base unit 3 that has received the connection signal from the corridor lamp 2, the base unit CPU 41 recognizes it and performs the following control. The slave unit ID and the type information of the medical device are read from the connection signal, and the patient associated with the slave unit ID, that is, the bed number is read with reference to the patient related information storage unit 35. Further, the time at that time is read from the internal clock of the master CPU 41 and used as the use start time. The type information, bed number information, and use start time information of the medical device 9 read in this way are linked to the name information of the patient using the medical device 9 and stored in the medical device information storage unit 36.

Further, when the master CPU 41 stores the use start time, it starts counting the use time from that time, and changes the color of the patient frame of the bed to which the medical device 9 is connected in the patient information displayed in the list. Thus, the fact that the medical device 9 is connected can be recognized from the list display.
FIG. 4 is an explanatory diagram showing a display in the standby state of the first display 31. A patient information list is displayed on the first display 31 in units of beds as shown in FIG. In FIG. 4, P is a patient frame in which individual patient information is displayed in a frame corresponding to the bed. In this patient frame P, a patient name display part P1, a bed number display part P2, a notification lamp P3 for notifying a call, and the like are provided. Q is a room number display frame.

FIG. 5 shows a state in which the medical device 9 is connected to the child device 1 in this display state, 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 the color of the patient frame P allows the patient who is using the medical device 9 to be grasped in a state where the patient information list is displayed, and the location of the medical device 9 being used can be easily grasped. Easy to manage.

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

  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 pop-up displayed, and R1 is a pop-up display frame. The patient detailed information including the usage time of the medical device 9 is popped up as shown in FIG. 6 by a predetermined operation for displaying the detailed information of the specific patient. In FIG. 6, the display “option connection time” indicated by P4 is the usage time display section.

Thereafter, when the use of the medical device 9 is finished, the plug is unplugged in order to move the medical device. When the plug is unplugged, the connected device detection unit 13 detects this and notifies the child device CPU 14, and the child device CPU 14 generates a removal signal to the parent device 3 via the corridor lamp 2 in the same manner as the connection signal. Sent.
In the base unit 3 that has received the removal signal, the base unit CPU 41 finishes counting the use time, and at the same time, a predetermined use end operation to be described later is not performed. Is 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 main unit 3.

This alarm sound can be eliminated by performing a predetermined use end operation before the plug is pulled out, and the plug can be removed with peace of mind.
Specifically, a target patient is selected from the operation unit 34 of the parent device 3 to display a detail screen, and a “medical device removal” button (not shown) is touched. With this operation, the master CPU 41 determines that the use of the medical device 9 has ended, and ends the use time counting. As a result, the time data (cumulative usage time data) counted after the usage time is determined is linked to the name of the patient using the medical device 9 and stored in the medical device information storage unit 36.
Then, by removing the plug from the connection terminal 12, the removal signal is continuously transmitted to the master unit 3, but the master unit CPU 41 performs a new operation such as an alarm sound when the use end operation is performed. do not do.

In this way, the use time is started in the parent device 3 in response to the connection signal of the medical device 9, and the patient uses it to receive the removal signal and end the count to store the data. The usage time of the medical device 9 can be grasped without being totaled, and the management of the usage state and the usage record of the medical device 9 becomes easy.
In addition, when the connection to the connection terminal 12 of the medical device 9 is disconnected, the main unit 3 emits an alarm sound. However, before the plug is removed, the main unit 3 performs a use end operation so that the alarm sound is generated even if the medical device 9 is removed. Is no longer issued, and there is no need for a cumbersome operation for stopping the alarm sound after the removal.
Furthermore, since the counting of the medical device usage time is completed in response to the use end operation, the medical device usage time can be managed with high accuracy.
In addition to the usage time of the medical device 9, the type of the medical device 9 and the patient who uses the medical device 9 can be grasped at the same time in the parent device 3, and thus can be managed in detail.

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

In response to the bed moving operation, if the moving patient uses the medical device 9, the base unit CPU 41 determines that the use end operation has been performed and calculates and stores the accumulated use time together with the end time. Then, when the bed number is changed to the destination, the bed number associated with the patient is changed and saved.
Further, even if the medical device 9 is detached from the slave unit 1 for movement in accordance with the movement of the patient and receives the removal signal, the alarm sound is not generated by ignoring it.

  Thereafter, if the medical device 9 is connected to the child unit 1 of the destination bed, the use start time is registered in the same flow as described above, and the use time count is restarted. After that, when use is completed and the medical device is removed, the usage time after restarting is added to the cumulative usage time associated with the previous patient, and a new cumulative usage time is calculated and saved. The

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

Thus, since the counting of the medical device usage time is completed by the bed moving operation, the usage time can be managed 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 separately perform a 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 stored in association with the patient, so it is continuously counted for the same patient, There is no need to perform cumbersome counting operations due to occurrence, and the counting of the usage time of the medical device 9 is not applied to different patients, thereby reducing the burden on the nurse.

In the above-described embodiment, the place where the medical device 9 is used can be confirmed by changing the color of the patient frame P in a state where the patient information list is displayed in units of beds, but the number of beds is small. When the patient frame P is relatively large, the type and usage time of the medical device 9 may be displayed in the patient frame P.
In addition, 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 parent device 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 associated with the patient and managed, they may be associated with the bed number instead of the patient and managed in the same manner.
