Title:
BACTERIA REMOVING FILTER UNIT FOR HEMODIALYZER AND HEMODIALYZER WITH BACTERIA REMOVING FILTER
Document Type and Number:
WIPO Patent Application WO/1998/050090
Kind Code:
A1
Abstract:
A bacteria removing filter unit for hemodialyzers which can effectively prevent bacterial pollution of a hemodialyzer, save a troublesome work for directly performing sterilization and disinfection at the time of reuse, and permit a bacteria removing filter itself to adequately be subjected to sterilization and cleaning without damaging biocompatibility. The bacteria removing filter unit comprises a filter casing (21) including a first bacteria removing chamber (22A) receiving therein a bacteria removing filter (25A) and a second bacteria removing chamber (22B) receiving therein a bacteria removing filter (25B), a connection (26) defined by having an outlet (23B) of the first bacteria removing chamber (22A) and an inlet (24A) of the second bacteria removing chamber (22B) approach each other, and a switching valve (27) provided on the connection (26) for switching between a position at the time of disinfection where middle portions of the connection on sides of the outlet and the inlet are made to communicate with each other to prevent a dialyzing fluid from flowing into and from a hemodialyzer (10), and a position at the time of dialysis where the middle portions are not allowed to communicate with each other, thus permitting the dialyzing fluid inflowing into and outflowing from the hemodialyzer (10).
