Blood collection assembly |
摘要 |
An automatically shieldable blood collection set is provided. The blood collection set includes a needle assembly having a hub to which a needle cannula is fixedly attached. A safety shield is telescoped relative to the hub and the needle cannula such that the hub and the needle cannula can be moved from a distal position where the needle cannula is exposed to a proximal position where the needle cannula is safely shielded. A spring is provided between the shield and the hub to propel the hub and needle cannula proximally relative to the shield and into surrounding relationship with the needle cannula. A retainer is provided for releasably holding the hub and needle cannula in a distal ready-to-use condition relative to the shield. An actuator releases the retainer and enables the hub and needle cannula to be propelled by the spring. A lock may be provided for preventing inadvertent re-exposure of the needle cannula. <IMAGE> |
