Device for painless insertion of needle for needle injected medication
First Claim
1. A device to insect hypodermic syringe needles into the patient without needle pain comprising:
- a sleeve with a closed end and a small opening in the center of said closed end said end of the sleeve being enlarged and provided with diametrically opposed slots and rubber bands fitting into said slots wherein, said rubber bands have a preselected coefficient of elasticity upon being attached to finger grips of a hypodermic syringe barrel and extended as the hypodermic syringe barrel is drawn back within said sleeve and upon release, to propel the hypodermic syringe needle through said small opening into the patient at such velocity to be undetectable by patient.

Abstract
A device to insert hypodermic syringe needles into the skin at such velocity as to render the penetration of said needle undetectable by the body therefore painless for the patient. The device to consist of a sleeve or tube (hereafter called sleeve) and elastic bands, the internal diameter of the sleeve to be slightly larger than the hypodermic syringe barrel in order to act as a guide for the hypodermic syringe barrel, one end of the sleeve is left open the other end is closed off, there being a small hole in the exact center of the closed end the hole is large enough for the needle to pass through but too small for the hypodermic syringe barrel this closed end of the sleeve is enlarged to absorb the shock of the hypodermic syringe barrel as it is stopped by the closed end of the sleeve and has places on the exterior of it for attachment of elastic bands which provide the energy to propel the hypodermic syringe barrel and needle.
