SUCTION APPARATUS FOR PERITONEAL CAVITY FLUID PERFUSION SYSTEM

摘要

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.

主权项

1. A suction apparatus for a peritoneal cavity fluid perfusion system configured to fill a peritoneal cavity with fluid and circulate the fluid through a filtering apparatus at a flow rate not smaller than 0.5 L per minute and not larger than 3 L per minute, the suction apparatus comprising:
a suction tube connecting the peritoneal cavity and the filtering apparatus and provided with a side hole formed in a wall of the tube in a peritoneal cavity-side tail end part; and a filter member having a tubular cap shape covering a tail end aperture of the suction tube and the side hole when fitted on the peritoneal cavity-side tail end part of the suction tube, formed from a foam body with an average aperture opening not smaller than 500 μm and not larger than 1000 μm, and having a thickness not smaller than 7.5 mm.
