PROBLEM TO BE SOLVED: To provide a notification device and a notification method by which it can be highly accurately notified that a puncture needle possibly comes off.SOLUTION: A notification device 10 includes: an optical separation detection sensor 20 which is attached to a patient together with an intravenous tube TB1 extending from a puncture needle 12 inserted into the patient and which detects a separation from the patient and a controller 30 performing notification on the basis of a result of detection of the separation detection sensor 20. The separation detection sensor 20 is electrically insulated.COPYRIGHT: (C)2014,JPO&INPIT【課題】穿刺針が抜ける可能性があることを高い精度にて通報できる通報装置及び通報方法を提供する。【解決手段】通報装置10は、患者に穿刺された穿刺針12から延びる点滴チューブTB1とともに患者に取り付けられ、患者から離間したことを検出する光学式の離間検出センサ20と、離間検出センサ20の検出結果に基づいて、通報を行うための制御器30と、を備え、離間検出センサ20は、電気的に絶縁されている。【選択図】図1
