PROBLEM TO BE SOLVED: To provide a safely used and inexpensive vacuum blood-collecting holder having good operability, wherein a pair of needle loading supporting members having a female twister engaged with a male twister fixed to the hub of a blood-collecting needle are combined so as to be slid in each inner peripheral surface roughly semicircular in section. SOLUTION: The other needle loading supporting member is slid toward one needle loading supporting member and these are coincided with each other. In this state, a blood-collecting needle is loaded. After blood-collecting work is over, the other needle loading supporting member is pushed down in an arrow direction 6, the other needle loading supporting member is unhooked from the outer edge part of one needle loading supporting member and, by pushing these sequentially in a horizontal direction, the other needle loading supporting member is moved in a direction away from one needle loading supporting member, and the twister engagement of a blood-collecting needle is released and dropped down. In this case, when the blood-collecting needle is removed from a holder, a male twister fixed to the hub of the blood-collecting needle to be released is easily and surely dropped while engagement thereof with the female twister of one needle loading supporting member is released. |
