摘要： A blood collection needle assembly (10) includes a holder body (14) having a tube receiving chamber (24) and a needle receiving chamber (26). A proximal needle (44) is mounted to the holder body and projects into the tube receiving chamber. A distal needle (70) is slidably mounted in alignment with the needle receiving chamber. A spring (86) is provided to urge distal needle into the needle receiving chamber, and a trigger (90) is provided for selectively permitting or preventing proximal movement of the distal needle. A transverse passage (68) between the two needles is formed from a transparent material and provides indication of venus axis. The blood collection needle assembly is used to collect a sample of blood in a conventional manner. After collection of the blood, the trigger is actuated to release the distal needle and the spring propels the distal needle in a proximal direction for safe shielding within the needle receiving chamber of the holder body.
