摘要：
A syringe for use in the pressurized injection of a fluid. The syringe includes a syringe barrel composed of a polymeric material having undergone expansion via blow molding, and an injection molded attachment mechanism which is integral with the syringe barrel and is located at the proximal end of the syringe barrel. The syringe barrel has a consistent wall thickness and is capable of withstanding pressures of at least 1200 psi. The syringe barrel includes a biaxial stretch sidewall as a result of the blow molding process while the attachment mechanism remains essentially unchanged by the blow molding process. The polymeric material can be, for example, polyethyleneterephthalate, cyclic olefin polymer, polypropylene, polystyrene, polyvinylidene chloride, polyethylene naphthalate and/or nylon.
