PROBLEM TO BE SOLVED: To provide a nurse call system for enlarging a movable range of a call transmitter by establishing radio connection between the call transmitter and a call receiver.SOLUTION: A nurse call system includes: plate slave units having slave unit connection sections a nurse call master unit, and a control unit. The system includes: call transmitters having movable sections for allowing each cared person to perform an operation to make a call and call receivers connected to the slave unit connection sections of the plate slave units and performing radio communication with the call transmitters. Each call transmitter includes: a transmitter CPU for detecting the operation of the movable section and generating a call signal and a radio transmission section for converting a call signal generated by the transmitter CPU into a radio signal and transmitting the signal to the call receiver. Each call receiver includes: a receiver connection section to be connected to the slave unit connection section of the plate slave unit and a radio reception section for converting a radio signal transmitted from the radio transmission section of the call transmitter into a call signal and transmitting the signal to the slave unit connection section of the plate slave unit by way of the receiver transmission section.COPYRIGHT: (C)2014,JPO&INPIT【課題】呼出送信器と呼出受信器との間を無線接続することにより呼出送信器の可動範囲を広げたナースコールシステムを提供する。【解決手段】子機接続部を備えるプレート子機とナースコール親機と制御機を有するナースコールシステムであって、被看護人が呼出しのための操作を行う可動部を有する呼出送信器とプレート子機の子機接続部に接続され呼出送信器との間で無線通信を行う呼出受信器とを備え、呼出送信器は可動部の操作を検出して呼出信号を生成する送信器CPUと送信機CPUにて生成された呼出信号を無線信号に変換して呼出受信器に送信する無線送信部とを備え、呼出受信器はプレート子機の子機接続部に接続される受信器接続部と呼出送信器の無線送信部から伝送されてくる無線信号を呼出信号に変換し受信器接続部を経由してプレート子機の子機接続部に送出する無線受信部を備えている。【選択図】図1
