CA 2366864
An automatically shieldable blood collection set is provided. The blood collection set includes a needle assembly having a hub with spaced apart inner and outer tubes. A needle cannula is fixedly attached to the inner tube. A safety shield is telescoped for movement into the space between the inner and outer tubes of the hub. The safety shield can be moved from a proximal position where the needle cannula is exposed to a distal position where the needle cannula is safely shielded. A spring is provided between the shield and the hub to propel the shield distally relative to the hub and into surrounding relationship with the needle cannula. A retainer is provided for releasably holding the shield in a proximal ready-to- use condition relative to the hub and the needle cannula. The retainer may be provided on a fin that extends transversely from the outer tube of the hub. An actuator releases the retainer and enables the shield to be propelled by the spring. The actuator may define portions of the wing spaced from the retainer. A lock may be provided for preventing inadvertent re-exposure of the needle cannula.
