Title: SYRINGE FOR AUTOINJECTOR DEVICE COMPRISING RESILIENT OUTER LAYER ALONG ELONGATE PLUNGER ROD
Abstract:
A syringe for use in an autoinjector, the syringe comprising a barrel having a front outlet, an open rear end, and a tubular body extending between the front outlet and open rear end. The tubular body has an internal diameter and defines a volume for containing medicament, and the open rear end has a diameter substantially equal to or greater than the internal diameter of the tubular body. The syringe further comprises a polymeric elongate plunger rod having a stopper at a forward end and a resilient outer layer along the length of the elongate plunger rod, where the elongate plunger rod is disposable within the barrel such that the stopper seals against the inside of the tubular body of the barrel and is slidable therein by axial translation of the plunger rod in the barrel.
