Abstract
A hand-held optimal injection high pressure syringe device, typically used for injecting viscous dye into a catheter or manifold. A pistol grip shape permits application of the full compressive force of the closing of the human hand. The syringe assembly is constructed of two major clear plastic sections plus a sealing tip attached to the injector end of the piston. The assembled syringe can be sterilized using standard procedures and disposed of following use. The simple design geometry permits use of efficient and low cost plastic injection molding techniques for manufacture.
