Abstract
A system for use with evacuated, rubber stoppered sample tubes (3) and double-ended needles (1) facilitates blood collecting operations and prevents accidental punctures from contaminated needles after use. The tube (1) is held in a tubular cartridge (12) with a sliding control (10) for to and fro controlled motion. A holder (2) engages the mid portion of the needle (3) and the cartridge and the sliding control slides the tube onto the needle after blood vessel puncture and slides it off the needle after collection. A sliding assembly (90) positions a shield (103) at the needle point (7) and the shield is impaled upon the point so that the needle may be discarded with the point protected. A finger control (35) release the needle while avoiding exposure to the point.
