Needle for blood sampling with a safety shield

摘要

The present invention is directed to a shieldable blood collection set. The shieldable blood collection set includes a fixture for connecting the blood collection set to a receptacle, an intravenous needle assembly including a needle cannula having a puncture tip, and a flexible tube extending between the fixture and the intravenous needle assembly. A shield assembly is in engagement with the needle assembly. The shield assembly is adapted for movement from a first position to a second position for protectively shielding the puncture tip of the needle cannula. The flexible tube includes a plurality of helical turns establishing a coiled structure. Such a coiled structure provides the blood collection set with an enlarged surface area for grasping by the palm of a user, thereby facilitating one-handed activation of the safety shield assembly.
