PROBLEM TO BE SOLVED: To detect blood leakage while reducing running costs of dialysis.SOLUTION: A dialyzer comprises: a dialyzer body 11 and an infrared camera 14 which is electrically connected to the dialyzer body 11 and detects radiation temperature distribution around the punctured-portion-side arm of a dialysis patient 1. The dialyzer body 11 comprises a controller which is electrically connected with the infrared camera 14 and determines the presence or absence of blood leakage on the basis of the radiation temperature distribution inputted from the infrared camera 14.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】透析のランニングコストの低減を図りつつ漏血を検出する。【解決手段】透析装置本体11と、透析装置本体11に電気的に接続され、透析患者1の穿刺部側の腕の周囲の放射温度分布を検出する赤外線カメラ14とを備える。透析装置本体11は、赤外線カメラ14に電気的に接続されて赤外線カメラ14から入力された放射温度分布に基づいて漏血の有無を判断する制御部を有する。【選択図】図1
