Abstract
A disposable needle assembly (10,10',10") includes a hub portion (12,12',12") and a hollow needle portion (22,22',22") having a distal tip (26,26',26"). A cap (28,28'28") has a neutral position along the needle portion (22,22',22") proximate to the hub portion (12,12',12") and an extended position for irreversibly capping the distal tip (26,26'26"). A tether (34,34'34") connects the cap (28,28'28") to the hub portion (12,12'12"). The cap (28,28'28") includes a pocket for locking the cap (28,28'28") over the distal tip (26,26'26") when the cap (28,28'28") is in the extended position.
