    摘要： A retractable needle assembly includes a housing having a sidewall defining a hollow bore, and an elongate plunger, the distal end of the plunger forming a reservoir within the hollow bore for containing a fluid therein. The plunger is adapted for slideable movement within the hollow bore. The assembly includes a hub disposed within the hollow bore and at least partially supporting a cannula therewith, and a needle retraction member engaged with the hub for manually selectable advancement with respect to a portion of the housing. The needle retraction member may be advanced from an initial position in which at least a portion of the needle is disposed outside the housing, to a retracted position in which the needle is fully surrounded by the housing. The elongate plunger may be advanced about the hub for extracting the fluid into the reservoir or expelling the fluid from the reservoir.

    摘要： The present invention relates to a self-blunting blood collection needle (55) in which a blunting member (26a) is deployed upon withdrawal of a blood collection tube (56a) from the tube holder (e.g., 136), to blunt the needle (22) and so safeguard the patient and the technician from inadvertent needle sticks. The blunting member (26a) is retracted to re-sharpen the needle (22) when a subsequent collection tube is inserted into the holder (136). The deployment and retraction of the blunting member (26a) is accomplished with a mechanism (142) that is responsive to the insertion and withdrawal of the blood collection tube (56a) to retract and deploy the blunding member (26a) accordingly. One feature of the present invention is that the mechanism (142) effects blunting and re-sharpening of the needle without requiring that the technician manipulates the mechanism in a manner different from that of conventional, non-blunting collection needles. Four mechanisms are disclosed: a rack and pinion mechanism (42); a cylindrical cam mechanism (142); a lever mechanism (242) and a reversing strap mechanism (342).
