Inventor(s): Bellhouse; Brian John (Islip, GB), Sarphie; David F. (Oxford, GB), Greenford; John Christopher (Abingdon, GB)
Assignee: Powderject Research Limited (Oxford, GB)
Filing Date:Aug 31, 2007
Application Number:11/848,432
Claims:1. A needleless syringe comprising: an energizing mechanism to provide a gaseous pressure; a particle cassette for holding particles to be injected; a nozzle configured to accelerate said particles; a silencer, downstream of said nozzle, for attenuating gas discharge noise; such that, upon activation of said needleless syringe, said particles are entrained in a gas flow, accelerated in said nozzle, and delivered to a target.

2. The needleless syringe of claim 1, wherein said nozzle is a convergent/divergent nozzle.

3. The needleless syringe of claim 1, wherein said silencer also serves, in use, to space a downstream end of the nozzle from a target.

4. The needleless syringe of claim 3, wherein the spacing is up to 35 mm.

5. The needleless syringe of claim 1, wherein said silencer provides a tortuous path from a downstream end of the nozzle to at least one outlet to the atmosphere.

6. The needleless syringe of claim 1, wherein said silencer comprises a sound attenuating medium.

7. The needleless syringe of claim 1, wherein said particle cassette comprises particles to be injected located between two rupturable membranes.
