PROBLEM TO BE SOLVED: To provide an infrared-type bed-leaving detector having high flexibility in installation and capable of reliably detecting bed-leaving motion of a care-receiver with little false detection.SOLUTION: A bed-leaving detector includes: an infrared sensor including an infrared-emitting part and an infrared-receiving part a control section for driving the infrared-emitting part and determining whether a care-receiver leaves a bed or not on the basis of a light-receiving signal from the infrared-receiving part transmission means for transmitting an output of the control section to an external device and a cylindrical pole part 3 erecting substantially perpendicular to a floor surface of a bed side, where an infrared sensor is incorporated in the pole part 3 so as to monitor a side of the bed from which the care-receiver gets in/out.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】設置の自由度が高く、しかも誤検出が少なく被介護者の離床動作を正確に検出し得る赤外線式の離床検出装置を提供する。【解決手段】赤外線発光部および赤外線受光部を含む赤外線センサーと、赤外線発光部を駆動するとともに、赤外線受光部からの受光信号に基づいて被介護者のベッドからの離床の有無を判定する制御部と、制御部の出力を外部機器に送信する送信手段と備えている離床検出装置において、ベッド脇の床面にほぼ垂直として立設される筒状のポール部3を有し、このポール部3内に、赤外線センサーがベッドの乗り降り側を監視するように組み込まれている。【選択図】図1
