Claim 1
Independent Claim
202 words
In a drainage fluid removing device having a rigid outer vessel, an inner flexible bag with an opening, means for suspending said flexible bag within said outer vessel, a drainage fluid suction tube inserted at one end thereof into said bag, and vacuum-creating means for evacuating the interior of said outer vessel thereby to cause the pressure within the bag to be negative and to draw drainage fluid through said suction tube into the bag: an improvement wherein said bag comprises seal line means fluid-tightly closing said opening of the bag and traversing said one end of said suction tube, a flat bag-shaped net member enclosing said one end of the suction tube, and a flexible flat bag-shaped cover member enclosing said net member and said one end of the suction tube and having an opening providing communication between the interiors of the cover member and the bag, said cover member being fluid-tightly secured to said one end of the tube and to said bag by said seal line means except at an unsealed part around said one end of the tube, whereby the interior of the bag is in communication with the interior of said outer vessel through said unsealed part.
