ABSTRACT:
Disclosed is a disposable safety syringe which comprises a reservoir and a tubular sheath. The reservoir serves to aspire therein or to inject therefrom a fluid, while the tubular sheath is integrally attached to and in fluid communication with the reservoir. In the sheath there is located a hollow needle and a needle-carrying means, suitably a bushing, which are axially slidable between a position of safety and protection for the needle within said sheath and an operative position in which the needle is fully protruding outside of the tubular sheath. When in this latter position, the needle is in air-tight fluid communication with the reservoir.
