Abstract
When sucking a fluid within a body cavity, foreign matter included in the fluid which exceeds the filtering diameter of a filtering apparatus may cause clogging of the filtering apparatus. Another concern is that a body cavity membrane getting stuck to a suction port of a suction tube may lead to the suction port being closed off. In response to such problems as these, provided is a suction apparatus, comprising a suction tube, and a filter member. The suction tube has side holes formed in a tube wall on a body cavity-side tail end part. The filter member has a tubular cap shape and covers a tail end aperture of the suction tube and the side holes, is formed from a foam body with an average aperture opening of 500-1000 μm, and has a thickness of 7.5 mm or more.
