Hypodermic syringe with foam sponge reservoir
First Claim
Patent Images
1. A dosage-dimensionable, composite, safely disposable, self-injectable hypodermic syringe, comprising:
- a minimally thin-skinned, hermetically sealable, resilient film-envelope, precisely formulated self-healingly, to effect a radially-contracting, transverse, liquid seal around the periphery of an axially penetratable cannula;
a cylindrical, injectant-saturated, absorbingly open-celled, reconformably collapsible, elastic, semi-rigid foam sponge reservoir media, having opposing outermost and discharge endwalls, comprehensively enclosed by said film-envelope; and
an axially penetratable cannula comprised of a needle body having a disc-butted end and a sharp-pointed end opposite one another, and a strategically placed side-vented discharge inlet perforation within the needle body, said cannula proportionally and centrically disposed internally of said foam sponge;
whereby said syringe facilitates an outermost endwall to discharge endwall, wholly maximal, axial compression there in between, compelling said needle to slidably penetrate projectedly there through to immediate tissue implantation per resultant simultaneous, thru-needle conductive total discharge of the injectant content.
