DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nurse call calling device, a nurse call calling method, and a recording medium, and more particularly, to a nurse call system using a radio telephone, the same call as a nurse call slave unit that made a call. The present invention relates to a nurse call calling device, a nurse call calling method, and a recording medium that can call only a wireless telephone whose location is registered in an area.

[0002]

2. Description of the Related Art Conventionally, a nurse call system using a radio telephone comprises a nurse call master, a nurse call slave, an exchange, a radio base station, and a radio telephone. At the time of calling from the nurse call slave unit, the nurse call master unit transmits a calling signal composed of slave unit information such as a calling area corresponding to the calling nurse slave unit and the telephone number of the wireless telephone to the exchange. The exchange has means for calling a wireless telephone via a wireless base station corresponding to the nurse call slave based on a call signal transmitted from the nurse call master, and the wireless telephone has a wireless base. It has means for displaying the slave unit information transmitted via the station.

The calling area A is a calling area including a ward in which a room where a patient who has made a nurse call using a nurse call slave unit is accommodated. For example, the radio telephones A and B perform location registration. It is assumed that The calling area B is a predetermined calling area other than the ward, and it is assumed that the location of the radio telephone C is registered.

[0004] The conventional nurse call system having such a configuration operates as follows. That is, when the patient presses his / her nurse call slave unit to make a call, the nurse call master unit that detects this call is sent to the wireless telephone A,
It generates a call signal composed of the B and C numbers, the patient's room number and bed number, and the child device information including the call area and the like, and transmits it to the exchange.

When the exchange receives the call signal transmitted from the nurse call master, the exchange reads the numbers of radio telephones A, B, and C included in the call signal, and reads the radio telephones A, B, and C.
C and call the handset information to the wireless telephones A, B,
C is displayed on the liquid crystal display section.

[0006] For example, when a nurse holding radio telephone A answers, a response signal is transmitted to the exchange. The exchange that has received the response signal from the radio telephone A stops the call of the other radio telephones B and C that was called at the same time as the radio telephone A, and transmits the response signal from the radio telephone A to the nurse call master. . The nurse call master unit that has received the response signal connects the exchange and the nurse call slave unit and the communication path of the wireless telephone A via the wireless base station. Thereby, a telephone call between the patient and the nurse becomes possible.

[0007]

However, this prior art has the following problems. The first problem is that in a conventional nurse call system, a nurse who answers a call almost immediately rushes to the patient's room and responds, but a nurse with a wireless telephone leaves the ward for errands. However, since a nurse call is made to this nurse's wireless telephone, if a nurse who leaves the ward responds by chance, it will take time to rush to the patient's room where the patient is located. That is, it gives anxiety.

[0008] In addition, during the daytime when many nurses are working, several nurses are always waiting at the nurse station, so nurses who leave the ward respond to nurse calls from patients. This means that each call rings, and you must listen to the ring until someone answers.

The reason is that when a nurse call master receives a nurse call from a patient without considering the nurse's whereabouts, all nurses in charge of the patient are simultaneously called.

The present invention has been made in view of such circumstances, and when a nurse call is made from a patient, a nurse who is in charge of the patient and who is in a call area of the patient is called a nurse.

Only the calling area 16 including the room of the patient who made the nurse call is set as the target of the nurse call, and an incoming signal is transmitted to the wireless telephone 15 registered in the calling area 16. In the nighttime when the number of nurses who work is relatively small, all call areas 16 are targeted for a nurse call, and an incoming signal is sent to the wireless telephone 15 registered in all call areas 16. An operation such as transmission becomes possible. Thereby, an efficient nurse call according to the time zone can be performed.

When a nurse call is made only to a predetermined call area 16 and no response is received even after a predetermined time has passed, another call area 16 adjacent to the call area 16 is called. Even a nurse call can be made. In other words, the incoming signal transmitting means 105 transmits the incoming signal to the wireless base station 14 in the calling area corresponding to the nurse call slave device 12 that made the call, Is not included in the location registration information among the wireless telephones 15 corresponding to the calling nurse's slave unit 12 corresponding to the telephone number included in the calling signal transmitted by the calling signal transmitting unit 101. For other wireless telephones 15 whose call area number of the call area corresponding to the radio telephone does not match the call area number of the call area corresponding to the nurse call slave unit that made the call contained in the call signal, another call is made. An incoming signal can be transmitted via a wireless base station in a calling area corresponding to the wireless telephone. Thus, it is possible to avoid a worst case in which a nurse cannot be called in spite of a nurse working at work.

In each of the above embodiments, the communication between the nurse call slave unit 12 and the nurse call master unit 11 is performed by wire, but may be performed wirelessly.
In addition, other configurations can be appropriately changed without departing from the spirit of the present invention.
