Jet injector


A jet injector is a type of medical injecting syringe that uses a high-pressure narrow jet of the injection liquid instead of a hypodermic needle to penetrate the epidermis. It is powered by compressed air or gas, either by a pressure hose from a large cylinder, or from a built-in gas cartridge, small cylinder, or spring (as in the Medijector Vision, Vitajet, Injex 23 and 30, or Insujet).
