SHIELDABLE NEEDLE ASSEMBLY WITH BIASED SAFETY SHIELD |
摘要 |
The present invention is directed to a needle safety device including a medical device, such as a needle holder or a syringe. The device includes a needle cannula having a puncture tip extending from an end of the medical device. A shield pivotably connected to the medical device is pivotal with respect to the needle cannul a between a shielded position encompassing the needle cannula and a retracted position pivotally spaced from the needle cannula. The shield includes a laterally extending lever, and the medical device includes a laterally extending arm. A spring having store d energy for biasing the needle cannula toward the shielded position is positioned between the lever and the arm. Movement of the lever and the arm toward each other pivot s the shield to the retracted position, and releasing the lever and arm allows the stored energy of the spring to pivot the shield into the shielded position. |
