Title: Colin D. Sheldrake and Needleless Syringe Innovation
Introduction
Colin D. Sheldrake is an inventor associated with Wiltshire, Great Britain, and Powder Pharmaceuticals Inc. His recorded patent work concerns a needleless syringe designed to deliver particles into the skin or mucosa of a vertebrate subject. The available information lists 1 patent for him.
Latest Patents
Sheldrake’s listed patent, “Needleless syringe,” describes a method for distributing particles in a gas flow and a syringe for needleless injection. A convergence in the gas-flow path creates a pressure reduction through the Venturi effect, drawing particles into the gas stream. The particles become entrained in the gas and are accelerated through an exit nozzle.
The patent also describes forming a transsonic gas jet by passing gas through a first convergence into a chamber, then directing the jet through a second convergence and along the nozzle. This design focuses on using controlled gas flow to carry and propel particles without a needle.
Career Highlights
The available information connects Sheldrake’s patent activity with Powder Pharmaceuticals Inc. His listed invention applies gas-flow principles to a needleless delivery device.
Collaborations
Sheldrake’s named coworkers include Brian J. Bellhouse and George Costigan. Their names are associated with the patent information provided.
Conclusion
Colin D. Sheldrake’s recorded invention explores how Venturi-driven gas flow can draw in and accelerate particles for needleless delivery, reflecting his contribution to syringe technology.
