ABSTRACT:
An auto-disable device for use with a sterile single use hypodermic syringe has a barrel adapter configured to attach to the outlet end of the syringe barrel, external to the barrel. A needle hub holding a hypodermic needle is affixed to the barrel adapter, the barrel adapter and the needle hub forming an assembly having a cavity with a passage for the flow of liquid through the device. An elastically-deformable sealing ring and a moveable sealing member having a head and a shaft are positioned in the cavity. The sealing member is moveable within the cavity. The ring and moveable sealing member are configured to form a seal, after a single use of the syringe, against a flow of liquid into the syringe for refilling of the syringe.
