PROBLEM TO BE SOLVED: To solve the problem that normal automatic vacuum suction operation becomes impossible or that anxiety feeling is imparted to a user when the area between the electrodes which constitute a sensor is contaminated in a conventional vacuum suction type urine sampler.SOLUTION: In the control unit of the vacuum suction type urine sampler constituted so that urine is detected by measuring the resistance between a pair of the electrodes installed on the side of a urine receiver of a urine vacuum suction route reaching a urine tank from the urine receiver through a urine transport tube by a control unit to operate a vacuum suction device, a state detecting circuit is constituted by connecting a detection resistor to the electrodes in series and connecting a manual operation switch to the series circuit of the electrodes and the detection resistor in parallel.COPYRIGHT: (C)2009,JPO&INPIT【課題】従来の真空吸引式採尿装置においては、センサを構成する電極間が汚れると正常な自動真空吸引動作が行えなくなってしまったり、使用者に不安感を与えてしまう場合もあった。【解決手段】そこで、本発明では、尿受け器から輸尿用チューブを経て尿タンクに至る尿真空吸引経路の、尿受け器側に設置した対を成す電極間の抵抗を制御装置において測定することにより尿を検知して真空吸引装置を動作させるように構成した真空吸引式採尿装置において、上記電極に直列に検出用抵抗を接続すると共に、電極と検出用抵抗の直列回路に並列に手動操作スイッチを接続して状態検出用回路を構成した真空吸引式採尿装置の制御装置を提案している。【選択図】図1
