Abstract
A compact injection syringe comprises a tubular housing and a piston pushed by means of a rod fitted with a pusher plate at its rear end. The piston thus expels the contents of the housing through the forward end via an injection needle. The piston rod-pusher plate assembly comprises an outer sleeve extending forwards from the pusher plate so that its forward, open end slides externally along the outside of the tubular housing, and is limited at its forward position by meeting a flange projecting radially outwards near the front end of the housing. Used in partic. for self-injection, as a thrown-away syringe. It is economical to make, compact and requires very few components; the sterility of the internal chamber is improved by the sliding sleeve, when it meets the forward scopic movement of this sleeve, when it meets the forward projecting flange, exactly defines the quantity of contents expelled from the syringe.
