Holder for blood collection needle with blunting mechanism |
摘要 |
Disclosed herein is a blood collection system comprising a blood collection tube, a tube holder, and a self-blunting blood collection needle. A blunting member is deployed upon withdrawal of a blood collection tube from the tube holder, to blunt the needle and so safeguard the patient and the technician from inadvertent needle sticks. The blunting member is retracted to re-sharpen the needle when a subsequent collection tube is inserted into the holder. The mechanism effects blunting and re-sharpening of the needle without requiring that the technician manipulate the mechanism in a manner different from that of conventional, non-blunting blood collection needles. Four types of mechanisms are disclosed: a rack and pinion mechanism; a cylindrical cam mechanism; lever mechanisms and a reversing strap mechanism.
