<p>An injection device comprising a hermetically sealed prefilled ampoule optimally suited for Blow-Fill-Seal manufacturing. The prefilled injection device is designed for mass production and ideally suited for fixed dose parenteral drugs. The apparatus is constructed to provide infusion therapy without the use of a syringe, eliminating the moving parts associated with syringes such as silicon, rubber, adhesives or tungsten. The ampoule is designed to be used with a variety of needle types, as well as needleless connections. The ampoule is resistant to changes in atmospheric pressure and provides a method for aspirating the air out of the ampoule prior to injection. The present invention comprises a hermetically sealed ampoule with a prepacked medication and pocket of nitrogen gas, an integrated bfs compatible collar, and a needle safety mechanism. The needle safety mechanism is connected to the integrated collar and comprises a self-activating shield (passive or active needle safety).</p> |
