| 摘要 |
The present invention is directed to a shieldable needle device (12). The shieldable needle device (12) includes a housing (30), a needle cannula (20), a tip guard (50) and an elongated flexibly resilient drive mechanism (80). The housing (30) includes a longitudinal slot (90) that extends along a wall of the housing. The drive mechanism (80) is bent within the housing (30) and includes a first end which extends through the longitudinal slot (90) and a second end which is anchored to the tip guard (50). Upon movement of the first end along the longitudinal slot (90), the second end extends and moves the tip guard (50) from a retracted position to an extended position thereby protectively surrounding a tip of the needle cannula (20). <IMAGE> |
