ABSTRACT:
A disposable safety syringe has a needle shuttle slidably located within a main syringe barrel. The shuttle has a pair of outwardly extending guide tabs which engage a guide slot formed in the barrel wall. The upper end of the needle shuttle is configured to accept a Wyeth needle cartridge having a needle attached to an ampoule by a carrier. A bushing and rod assembly are mounted in the barrel below the ampoule. After use, the needle shuttle is maneuvered downwardly by the guide tabs to a locking position in which the needle attached to the ampoule is housed within the barrel for safe disposal.
