PROBLEM TO BE SOLVED: To provide a temperature/humidity exchanger for respiration capable of stably using heat/humidity accumulation body by suppressing adhesion of secretion or the like discharged along with exhalation to the heat/humidity accumulation body in the temperature/humidity exchanger for respiration connected with an artificial airway.SOLUTION: A temperature/humidity exchanger 1 for respiration connected with an artificial airway comprises: a housing 10 that includes a patient-side tube 20 in which a first opening 21 connected with the artificial airway, is formed, a retaining wall part 35 extending to a second opening 22 side with a gap formed toward the patient-side tube 20, a housing body 30 extending to a third opening 35A side with a gap formed toward the retaining wall part 35, and a communication hole a heat/humidity accumulation body 60 and a storage container 50. The temperature/humidity exchanger is configured to be able to communicate between the first opening 21 and a fourth opening 34A via the heat/humidity accumulation body 60.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2017,JPO&INPIT【課題】人工気道が接続される呼吸用温湿度交換器であって、呼気とともに吐出される分泌物等が湿熱蓄積体に付着するのを抑制して、湿熱蓄積体を安定して使用可能な呼吸用温湿度交換器を提供すること。【解決手段】人工気道が接続される呼吸用温湿度交換器1であって、前記人工気道が接続される第1開口部21が形成された患者側管20と、前記患者側管20と間隙をあけて第2開口部22側に伸びる保持壁部35と、前記保持壁部35と間隙をあけて前記第3開口部35A側に伸びるハウジング本体30と、流通孔とを有するハウジング10と、湿熱蓄積体60と、収納容器50と、を備え、湿熱蓄積体60を介して第1開口部21と第4開口部34Aとを流通可能に構成されていることを特徴とする。【選択図】図6
