PROBLEM TO BE SOLVED: To eliminate the generation of noise during humidification, to completely block a situation of letting bacteria having grown in water flow out to a patient side, to effectively exert a humidification function even if water inside a container is reduced to the vicinity of a bottom part of the container from a full water state, and to allow easy maintenance or the like of a hollow fiber membrane module.SOLUTION: In this hollow fiber membrane type humidification device, a lid body 2 having a gas inflow port 10 and a gas outflow port 11 is detachably covered on the container 1 filled with water W, a flat hollow fiber membrane module 3 capable of being as thoroughly as possible immersed in the water W is placed on the bottom part 1a inside the container 1, an inlet 15 of the hollow fiber membrane module 3 and the gas inflow port 10 are connected, and an outlet 16 of the hollow fiber membrane module 3 and the gas outflow port 11 are connected.COPYRIGHT: (C)2013,JPO&INPIT【課題】加湿時における騒音の発生をなくし、水中に発生した菌を患者側に流出する事態を完全に阻止するとともに、容器内の水は満水状態から容器の底部近傍まで減少しても加湿機能を有効に発揮させ、しかも、中空糸膜モジュールのメンテナンス等も簡便に行えるようにする。【解決手段】この中空糸膜型加湿装置は、水Wを充填する容体1に気体流入口10と気体流出口11を有する蓋体2が着脱自在に被蓋され、この容体1内の底部1aに水Wに可能な限り浸漬できる扁平形状の中空糸膜モジュール3が設置され、この中空糸膜モジュール3の入口15と気体流入口10とが接続され、かつ中空糸膜モジュール3の出口16と気体流出口11とが接続されている。【選択図】図1
