Abstract: A female connector including: a cylindrical core member having a luer taper on a distal inner surface thereof and a tube bonding portion formed on a proximal end inner surface and being formed with a flange at a distal extremity thereof; a cylindrical housing having a male screw formed on an outer surface thereof and mounted to an outer periphery of the core member without being fixed, and a stopper fixed at a position apart from the flange of the core member, wherein the distance (L1) between the flange and the stopper is larger than the length (L2) of the housing in the axial direction when a male connector is connected to the female connector.

Abstract: A filter set for recovering desired blood components from human blood and a method for recovering blood components using the filter set are provided. The filter set includes a bag body and an accommodation vessel for accommodating the bag body therein in a compressed condition. In the method the bag body is provided in the accommodation vessel and is compressed and blood is passed through the compressed bag body. Blood components are adhered to the compressed filter material in the bag body. Thereafter, the compression of the bag body is relieved and a washing solution is passed through the expanded bag body to remove the blood components contained therein.

Abstract: A method for making an outer cannula of an intravenous cannula. An insert pin (3) is inserted into an outer cannula (1) having a hub (12) and a tube (11) made of a shape memory polyurethane resin and having an untreated distal end portion, until a tip end of the insert pin (3) reaches a position retracted from a distal end of the tube (11). While holding the position of the insert pin (3), the tube (11) with the insert pin (3) is forced into a cavity in a mold (4) heated to a temperature of 120.degree. C. to 180.degree. C. until the insertion of the tube into the cavity is obstructed. Subsequently, the insert pin (3) is moved within the tube (11) toward the extremity of the tube until the tip end of insert pin (3) reaches a first predetermined position in the mold (4). After maintaining the tube at the mold temperature until the tube is softened, the insert pin is further moved within the tube toward the extremity thereof and held in position for a certain period of time.
