BLOOD COLLECTING APPARATUS AND SLIDING TYPE DUCT SWITCHING MEANS

PROBLEM TO BE SOLVED: To provide a blood collecting apparatus capable of eliminating fears such as a failure to close a clamp by an operator, contamination of a blood collecting bag by blood collection initial flow due to the failure, and problems of a sealing member which cannot be broken quickly or forms broken pieces.SOLUTION: In a first blood collecting tube T1.1, a first end is connected to a blood collecting needle 8. In a second blood collecting tube T1.2, a second end is connected to the blood collecting bag 4. A sliding type duct switching means 60 is disposed between the first blood collecting tube T1.1 and the second blood collecting tube T1.2, and a first end of an initial flow blood tube T2 is connected to the duct switching means 60. A second end of the initial flow blood tube T2 is connected to a blood collection first flow elimination bag B. In the blood collecting apparatus 1, the sliding type duct switching means 60 regulates opening/closing of a liquid duct from a liquid duct 62a of the sliding type duct switching means 60 to the first blood collecting tube T1.1, to the second blood collecting tube T1.2, and to the initial flow blood tube T2.
