PROBLEM TO BE SOLVED: To provide a nurse call system by which a corridor light makes it easy to confirm with ease that what has dropped (what type of equipment), and where (from a plate subunit, from a handset subunit, etc.) the equipment has dropped near the patient's bed.SOLUTION: In a nurse call system, a plate subunit includes at least a plate subunit connection portion to which a handset subunit and a grip subunit are connected, and the handset subunit includes a handset subunit connection portion for connecting the grip subunit, further includes a dropping detection portion that detects that the grip subunit is dropped from the plate subunit connection portion or the handset subunit connection portion and transmits a drop detection signal to which a subunit ID is added, to the corridor light, and the corridor light is provided with a corridor light CPU that performs control to display a result of detection of the location by the dropping detection portion on a display portion of the corridor light.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】患者のベッド近傍で何が（何の種類の機器が）、どこで（プレート子機からか、ハンド子機からかなど）脱落したのかを廊下灯でわかりやすく確認することができるナースコールシステムを提供する。【解決手段】ナースコールシステムにおいて、プレート子機は、少なくともハンド子機、握り子機が接続されるプレート子機接続部を有し、当該ハンド子機は、握り子機を接続するためのハンド子機接続部を有し、プレート子機接続部又はハンド子機接続部から握り子機が脱落したことを検出するとともに、子機ＩＤを不可した脱落検出信号を廊下灯に送信する脱落検出部を備え、当該廊下灯は、脱落検出部が何れで脱落したかを検出した結果を廊下灯の表示部に表示する制御をおこなう廊下灯ＣＰＵを備えたことを特徴とする。【選択図】図１
