Abstract
This invention related to a simple device for hypodermic pressure-injection which does not make use of needles for introducing the vaccine into the patient's body, and which is fully constituted by low cost disposable material self-destroying after being utilized a single time. This device already contains within it, a single metered dose of vaccine or medication to be injected and, when in use, it comprises solely four elements; and injector nozzle with an outlet orifice, a sealing disc, a cylindrical body and the dose itself of vaccine to be injected. The device, referred to as disposable capsule, is used at the front portion of a pressure-injection apparatus and aims at establishing a vaccination means which is simultaneously disposable, fast, safe, of low operational cost and mainly that does not make use of hypodermic needles and whose assembly which touches the patient at the injection site is self-destroyed after a single use, thereby avoiding any possibility of reuse and consequent possibility of disseminating blood-transmittable diseases.
