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.
