ABSTRACT:
A disposable hypodermic needle is disclosed, including a conventional hollow needle having a sharp distal end and a plastic, integrally formed closure means, including a shank mounted on the distal end, plastic wings for enclosing the distal end for disposal of the needle. The wings include interlocking means to make the closure permanent, and include hinges for allowing the wings to be manipulated relative to the shank. Grips are provided on the wings for safe handling of the hypodermic needle. A sheath is provided for the distal end of the needle for maintaining its sterility and preventing accidental injury to the practitioner. In one embodiment, a lock hub is provided at one end of the shank to allow connection to a catheter, and in another embodiment, a tube is provided between the shank and the lock hub.
