ABSTRACT:
A protective needle sheath is operatively extendable for protecting the sharpened needle point of a hypodermic syringe. The sheath comprises a pair of telescopic enclosure shields mounted to the needle base. Detent locking members lock the shields in a non-retractable extended protective position. The sheath is maintained in protective position about the needle in the event that the needle is detached from the syringe body.
