ABSTRACT:
A syringe which has been prefilled to include a prescribed liquid and also a gas. The syringe includes a reservoir, a chamber which is in fluid communication with the reservoir and an outlet which is interposed between the chamber and the reservoir. Severing the chamber from the reservoir at the outlet will provide a syringe that includes a reservoir and an outlet. Prior to severing the chamber from the reservoir, the syringe may first be oriented such that all gas is directed into the chamber so that the syringe's reservoir will be completely filled with non-compressible fluid such as the medicating liquid.
