Abstract

PURPOSE: To avoid danger of contamination or formation of thrombus by use of a cannula tube by providing a valve formed of a mandrin and the cannula tube to be adjacent to a second end part of the cannula tube. CONSTITUTION: A reinforced part 33a of a mandrin 12 has a rectangular cross- sectional surface, so flow at a side surface part around the reinforced part 33a is assured, and inflow of fluid is made from an injection hole 17 to a fluid passage 34. A hose part 17a of which back end part 17b is adhesion-fixed to a wall surface of a connector 15 is provided in a space in the connector 15 at which the injection hole 17 is terminated, and a peripheral part of the hose part 17a is loosely in contact with an inner wall surface of the connector 15. The hose part 17a isolates the injection hole 17 from inner parts of the connector 15, so a valve is formed to be opened by fluid pressure in the injection hole 17. Unless fluid is injected through the injection hole 17, a check valve 35 is closed, thereby blood components are completely prohibited from getting into a cannula tube 14.
