Next, the receiver 41 of the nurse call base unit 40
On-hook, the call between the nurse call master device 40 and the nurse call slave device 1 ends. When the control device 30 detects that the nurse call slave device 1 has ended the call, the call from the nurse call slave device 3 is set as the first priority in the memory 32. At the nurse call base unit 40, a ringing tone caused by a call from the nurse call slave unit 3 sounds again. In this state, when a response operation is performed by the receiver 41 in the nurse call master device 40, the nurse call slave device 3 and the nurse call master device 40, which are the first-priority response destinations stored in the memory 32 of the control device 30, are connected. It goes into a call state.

As described above, when a plurality of nurse call handsets are successively called, the answer / end operation is repeated by the receiver 41 of the nurse call master unit 40, so that the data is stored in the memory 32 of the control device 30. According to the priorities, it is possible to make a telephone call (first-come-first-served response) with a nurse call slave having a higher priority.

Next, a description will be given of a channel selection response in the nurse call master unit 40 when a plurality of calls are simultaneously made from the nurse call slave unit.

When a call is made from the nurse call slave unit 3 in the sick room 201 after the nurse call slave unit 1 in the sick room 101 is called, the bed number 101 is stored in the memory 32 of the control device 30 as the first priority. -1 is stored, and the bed number 201-3 is stored as the second priority. In this state, the nurse call base unit 40 is depressed by pressing the channel selection switch 55 of the nurse call base unit 40 to which the nurse call base unit 3 having the second highest priority is assigned.
Transmits a response command (nurse call master device response 201-3) to the control device 30. The microcomputer 3 of the control device 30
1 is a connection command (connection 20) to the hospital room adapter 80.
At the same time as transmitting 1-3), a connection command (connection 201-3) is transmitted to the nurse call master device 40, and the nurse call master device 40 and the nurse call slave device 3 enter a talking state.

As described above, even when a plurality of nurse call sub-units are sequentially called, an arbitrary nurse call sub-unit is directly selected by the channel selection switch of the nurse call parent unit 40, whereby the control device 30 is controlled. Regardless of the priority order stored in the memory 32, a tuning response can be made to any nurse call slave unit.

On the other hand, when a call is generated from the nurse call slave unit, control device 30 transmits a call information command to nurse call master device 40 and simultaneously transmits a call information command to PBX main device 60. By receiving the call information command, the PBX main unit 60 makes a call to the multi-function telephone 61 as an extension telephone. In the multi-function telephone 61, the call type of the caller and the bed number of the hospital room are displayed on the liquid crystal display unit 62, and a ring tone sounds. A response call can be made to the nurse call cordless handset that has been called by the response operation on the multifunctional telephone 61.

Normally, when a nurse call intercom apparatus is installed in a ward, automatic answering and selection of a call from all nurse call slave units and a response call test with a nurse call master unit or a multifunctional telephone before the hospital opens. Performed by station response.

Even during operation after opening the hospital, if additional work such as a function change or additional equipment is performed, calls from all nurse call slave units and answering call tests with the nurse call master unit and the multifunctional telephone are performed. In the same manner, it is performed by an automatic response or a channel selection response.

[0018]

However, in such a conventional nurse call intercom apparatus,
When changing functions or constructing additional equipment after opening the hospital, the ward is always in operation 24 hours a day and 365 days a year. Frequent calls, and the priority of test calls may be higher than that of patients with high urgency, preventing the nurse from checking the patient's condition, There is a problem in that the response also hinders the work of the worker performing the test operation.

The present invention has been made to solve such a problem, and it is an object of the present invention to provide an intercom system in which a test worker can perform a test operation without interrupting the work of a nurse.
