COLLAPSIBLE SYRINGE FOR FLUID DELIVERY SYSTEM

摘要

A collapsible syringe assembly for a fluid delivery system is a multi-component device that includes a cylindrical pressure jacket and a collapsible syringe that is received within the pressure jacket. The collapsible syringe includes a cap member and a compressible or deformable sidewall member. The collapsible syringe in one embodiment is adapted to be secured to the pressure jacket by the cap member. The cap member is formed with a discharge port, which may be formed as conventional luer fitting. The discharge port is disposed coaxially within an annular wall on the outward facing side of the cap member and may be recessed within the annular wall.
