The nurse call slave of such a nurse call system is composed of a call slave that is operated when a patient calls a nurse, and a wall slave that is provided on a wall surface with a connection terminal of the call slave. In addition, a microphone and a speaker for making a call are provided in a wall slave or a call slave, and the call slave and the wall slave are paired and installed according to the number of beds.

JP 2004-96409 A

  As described above, in the case of the conventional nurse call system, nurse call slaves are installed in accordance with the number of beds. Therefore, a single nurse call slave, that is, a caller and a wall slave in a private room. It was only installed. For this reason, the bed position is limited by the movement range of the caller operated by the patient. If it is absolutely necessary to move beyond this range, an extension cord can only be connected to the caller, and in this case, the cord will interfere with nursing work and disconnection may occur due to pressure or tension. There were problems in terms of safety and reliability.

  However, there is a desire to be able to easily change the bed position in accordance with the patient's medical condition or desire or the arrangement of medical equipment in the private room. Also, in recent years, there are cases where two-person rooms are used as private rooms, in which case one of the two wall slave units is unused even though there is sufficient space to change the bed position. Requires a troublesome operation to remove one of the nurse call slaves or change the setting so that one of the nurse call masters is not used, and the two wall slaves depending on the bed position. I couldn't use the machine properly.

  Therefore, the present invention has been made in view of such problems, and a nurse call system that makes it easy to change the bed position in a private room without requiring a system change or troublesome setting change operation of the conventional nurse call system. It is intended to provide.

In order to solve the above-mentioned problem, the invention of claim 1 has a function of calling a nurse and having a nurse call slave set installed for each bed, and a function of responding to a call from the nurse call slave set. The nurse call master unit installed in the station, the corridor lamp that lights up in front of the hospital room when the call by the nurse call slave unit, and the call from the nurse call slave unit are detected to control the lighting of the corridor lamp In a nurse call system comprising a corridor light adapter installed for each corridor light and a controller for controlling communication between the corridor light adapter and the nurse call master device, the nurse call slave device is installed on the wall surface. Of the corridor light adapter, and the corridor light adapter for the private room among the corridor light adapters includes a plurality of child device connection portions to which the wall child devices are connected, and the child device. A slave unit status determining unit that detects connection / non-connection of the paging unit in each of the continuation units and determines a use state of the wall unit, and the slave unit status determination unit includes any one of the wall unit slave units. It is determined that a disconnection has occurred except for recognizing the connection of the caller only to the terminal, and a disconnection signal is generated and transmitted to the nurse call master unit.
According to this configuration, even if the wall slave unit is provided at a plurality of locations, the corridor lamp adapter grasps the wall slave unit to which the call slave unit is connected, and only one of the wall slave units is connected to the call slave unit. It is determined that the disconnection occurs except for recognizing. That is, if a paging device is connected to one wall surface device, it is not recognized as a disconnection. Therefore, it is possible to make a plurality of wall surface handsets correspond to one calling handset, and it is possible to easily change the bed position in the private room. And if the handset is disconnected, it can be detected.
Further, when changing the double room to a private room, only the corridor lamp adapter needs to be changed, and there is no need to greatly change the conventional system.

According to a second aspect of the present invention, in the configuration according to the first aspect, the slave unit status determination unit changes the slave unit connection unit that has confirmed the connection of the paging unit to an unconnected state, and then performs other operations within a predetermined time. A disconnection signal is generated and transmitted to the nurse call master unit when the connection of the call slave unit cannot be recognized by the slave unit connection unit.
According to this configuration, it is possible to detect if the caller is disconnected during operation, and when the wall slave connected to the caller is changed due to bed movement, the change is automatically recognized and it is not determined that a disconnection has occurred. . Therefore, a separate connection change operation is not required at the nurse call parent device or the like each time the wall surface child device to be used is changed.

According to the present invention, even if the wall slave unit is provided at a plurality of locations, the corridor lamp adapter grasps the wall slave unit to which the call slave unit is connected, and the call slave unit is connected to any one of the wall slave units. If it is, it is not recognized as a disconnection. Therefore, it is possible to make a plurality of wall surface handsets correspond to one calling handset, and it is possible to easily change the bed position in the private room. And if the handset is disconnected, it can be detected.
In addition, when changing from a double room to a private room, only the corridor lamp adapter needs to be changed, and it is not necessary to make a major change to the conventional system. Is not necessary.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described in detail with reference to the drawings. FIG. 1 shows an example of a nurse call system according to the present invention. In FIG. 1, 1 is a nurse call cord for a patient to call a nurse, 2 is a corridor lamp that is installed in front of a hospital room and lights up when the patient calls the nurse call cord 1, and 3 is a nurse call. The corridor lamp adapter 4 detects the call from the handset 1 and controls the lighting of the corridor lamp 2. The nurse call master unit 4 responds to the call from the patient and makes a call. It is a controller that controls communication between the machines 4. However, the corridor lamp adapter 3 is a corridor lamp adapter for a private room corresponding to the private room, and one of them is shown in a circuit block diagram.

  The corridor lamp 2 and the corridor lamp adapter 3 are installed for each hospital room, and the nurse call cordless handset 1 is connected to the corridor lamp adapter 3 via the transmission line L1 for each patient room. The corridor lamp adapter 3 is connected to the controller 5 via the corridor lamp main line L2, and the controller 5 is connected to the nurse call master unit 4 via the transmission line L3.

  The nurse call handset 1 includes a wall face handset 1a and a call handset 1b. The wall face handset 1a has a connector 10 for connecting the call handset 1b, a microphone 11 for a patient to talk to a nurse, and A speaker 12 is provided. The calling handset 1b has a push button 13, and is connected to the wall face handset 1a via a cable L5. The push button 13 is pressed when the nurse is called by being placed on the bed or in the vicinity of the bed. Is done.

  As shown in FIG. 1, the corridor lamp adapter 3 includes a storage unit 16 for storing the connection status of the nurse call slave unit 1, a timer unit 17 for counting a predetermined time, and a first unit for communicating with the nurse call master unit 4 An interface (first IF) 18, a second interface (second IF) 19 for communicating with the nurse call slave device 1, an adapter CPU 20 for controlling the corridor lamp adapter 3, and the like are provided. The second IF 19 includes two connection portions (a first connection portion 19a and a second connection portion 19b) for connecting the nurse call slave unit 1.

Next, the operation of the nurse call system configured as described above will be described. However, since the call response operation of the nurse call is the same as that of the conventional nurse call system, the description thereof will be omitted. Here, the nurse call slave connection determination process by the hallway light adapter 3 will be described.
The corridor lamp adapter 3 transmits a call signal to the nurse call master unit 4 via the controller 5 when the connected nurse call slave unit 1 is called, and controls the lighting of the corridor lamp 2 in a conventional manner. On the other hand, the following operations are performed.

  When the system is first turned on (more precisely, when the corridor lamp adapter 3 is turned on), an initial determination processing operation is performed. By this initial determination process, it is determined whether the nurse call slave device 1 connected to the second IF 19 of the corridor lamp adapter 3 is connected to the first connection portion 19a or the second connection portion 19b. FIG. 2 is a flowchart showing the flow of the initial determination process, which will be described with reference to this figure.

  When the controller 5 is turned on, electric power is supplied to the corridor lamp adapter 3. The activated corridor lamp adapter 3 performs the following control under the control of the adapter CPU 20. First, it is determined whether the call handset 1b is connected to the wall surface handset 1a connected to the first connection portion 19a of the second IF 19 (S1). Thereafter, it is determined whether or not the calling device 1b is connected to the wall surface device 1b connected to the second connecting portion 19b (S2, S3). This determination is carried out by managing whether or not the calling device 1b is connected to the wall surface device 1a, for example, by managing the impedance of the connector 10.

Thus, if it is determined that the calling unit 1b is connected only to the wall surface unit 1a of the first connection unit 19a, a communication line is established between the first connection unit 19a and the nurse call base unit 4 to establish the first connection unit. The nurse call handset 1 is operated via 19a (S6). Conversely, if it is determined that the handset 1b is connected only to the second connection unit 19b, a communication line is established between the second connection unit 19b and the nurse call parent unit 4 via the second connection unit 19b. The nurse call cordless handset 1 is operated (S4).
Then, the storage unit 16 stores which of the two connection units 19 a and 19 b of the second IF 19 has established a communication line.

  Further, if it is determined that the handset 1 is connected to both the first connection unit 19a and the second connection unit 19b, and if both are determined to be unconnected, it is determined that a dropout or disconnection has occurred. Then, a disconnection signal is transmitted to the nurse call parent device 4 via the first IF 18 and the control device 5, and the nurse call parent device 4 issues a warning of occurrence of the disconnection (S5). In response to this warning, the nurse or the like confirms the drop or disconnection of the nurse call cordless handset 1 and repairs it, and when a predetermined recovery operation (S7) is performed, the alarm is stopped (S8) and the nurse call is performed again. The initial determination process of the handset 1 is performed.

In this way, even if the wall slave unit 1a is provided at two locations, the corridor lamp adapter 3 grasps the wall slave unit 1a to which the call slave unit 1b is connected, and the call slave unit 1b is connected to any one wall slave unit 1a. If it is connected, it is not recognized as a disconnection. Therefore, it is possible to make the two wall surface slaves 1a correspond to the one handset 1b, and it is possible to easily change the bed position in the private room.
Further, when changing the double room to a private room, only the corridor lamp adapter 3 needs to be changed, and there is no need to greatly change the conventional system.
When the caller 1b is not connected to any wall slave 1a at the time of start-up or recovery operation, the nurse call master 4 issues an alarm, so that the nurse can quickly recognize it, Easy to deal with.

Next, an operation (automatic connection determination process) when the nurse call handset 1 is disconnected or disconnected in a state where the system is operating will be described. This process is continued after the initial determination process of the nurse call slave unit 1 is performed. FIG. 3 is a flowchart showing the flow of this automatic connection determination process, and the description will be made based on this flow.
In this example, it is assumed that the caller 1b is connected to the wall slave 1a connected to the first connecting portion 19a.

  When the caller 1b of the nurse call slave 1 connected to the first connection unit 19a is dropped in the system operating state (S11), the timer unit 17 starts measuring 20 seconds, for example (S12). The adapter CPU 20 constantly monitors the state of the connector 10 of the wall slave unit 1a connected to the first connecting portion 19a and the second connecting portion 19b, for example, the impedance of the connector 10, and from this change in impedance. It is determined whether the handset 1b is dropped.

At this time, that is, before the timer unit 17 expires, if the disconnection is recovered and the connection of the handset 1b is recognized in the first connection unit 19a (Y in S13), the connection is made to the first connection unit 19a. The nurse call cordless handset 1 is operated and the operation is resumed (S15). In this case, it is determined that the caller 1b is temporarily disconnected from the connector 10 but is immediately connected, and the operation is resumed.
However, if the caller 1b is not connected to the first connection 19b for 20 seconds (Y in S14), is the caller 1b connected to the wall slave 1a connected to the second connection 19b next? Judgment is made (S16). At this time, if it is determined that the caller 1b is connected, the nurse call slave 1 connected to the second connection unit 19b is operated (S18). Further, the storage unit 16 is rewritten in response to the connection change. In this case, it is determined that the wall slave 1a to be used after the bed is moved is changed, and the communication line is changed.
The reason for determining the connection of the caller 1b after the elapse of 20 seconds (S14) is that the movement frequency of the bed is very small compared to the dropout frequency of the caller 1b.

However, if it is determined that the handset 1b is not connected to the second connection unit 19b (N in S16), it is determined that the disconnection disconnection has occurred, and the disconnection signal is sent to the nurse call master 4 via the first IF 18 and the controller 5. Is transmitted, and the nurse call parent device 4 issues a disconnection alarm (S17).
When a predetermined recovery operation (S19) is performed after the nurse call slave unit 1 has been removed or repaired after the disconnection or disconnection of the nurse call slave unit 1 has been performed by a nurse or the like who has recognized the dropout by the notification of the nurse call master unit 4, the notification is issued. Stop (S20) and start counting again for 20 seconds (S12), and the automatic connection determination process of the nurse call slave unit 1 is continued.

  In this way, if the caller 1b is disconnected during system operation, it can be detected, and even if the wall slave 1a to which the caller 1b is connected due to bed movement is changed, it is automatically recognized and newly called. Since the nurse call slave unit 1 connected to the machine 1b is operated to establish a communication line with the nurse call master unit, a separate connection change operation is not required.

In the above embodiment, the corridor lamp adapter 3 is provided with the connecting portions 19a and 19b of the two nurse call slave units 1 so that the call slave unit 1b can be changed between two locations. It is possible to easily implement a configuration in which three or more are installed so that the caller 1b can be changed at a plurality of locations.
The nurse call handset 1 is composed of a wall handset 1a with a built-in microphone 11 and a speaker 12 and a call handset 1b provided with a call button 13. The wall face handset 1a includes a call handset 1b. It is good also as a structure which provided only the connector 10 to connect and provided the microphone and the speaker in the handset 1b. Furthermore, the corridor lamp adapter 3 and the corridor lamp 2 may be formed integrally.
