Problem to be solved: to provide an excess anesthetic gas detector capable of detecting the exchange time of the recovery filter of the excess anesthetic gas in real time without measuring the weight of the recovery filter.Solution: the excess anesthetic gas detector 1 comprises a detector body 2 having an intake port for introducing an excess anesthetic gas, a sensor for measuring the concentration of an excess anesthetic gas contained in the detector body, and a warning lamp for turning on the basis of the gas concentration measured by the sensor. The sensor is a second tin semiconductor gas type gas sensor, and further includes a mounting device 4 for attaching the suction vessel 3 through which an excess anesthetic gas passes through the intake port.Diagram【課題】余剰麻酔ガスの回収フィルタの交換時期を、回収フィルタの重量を測定することなくリアルタイムに検知することが可能な余剰麻酔ガス検知器を提供する。【解決手段】余剰麻酔ガス検知器1は、余剰麻酔ガスを取り入れる吸気口を有する検知器本体2と、検知器本体に内蔵される余剰麻酔ガスの濃度を測定するセンサと、センサが測定したガス濃度に基づき点灯する警告灯と、を備える。センサは、酸化第二スズ半導体式ガスセンサであり、吸気口に余剰麻酔ガスが通る吸着容器3を取り付ける取付具4をさらに備える。【選択図】図1
