Abstract

A hypodermic projectile which is adopted to inject a liquid drug into an animal or human upon contact therewith, the projectile including a hollow body having a thin, readily frangible, front wall and a rigid rear wall with a liquid drug in between. Also present in the hollow body is a gas, under pressure, which forces the drug out of the projectile when the front wall shatters. The thin front wall shatters on contact with an animal or human having a plurality of sharp cutting edges which penetrate the skin and any covering on the body, thereby facilitating entry of the drug into the animal or human being treated.

Claims

1. A hypodermic projectile adapted to inject a liquid drug into an animal or human target upon impact therewith comprising:

a hollow body having a readily shatterable front wall, and a rear wall;

a side wall which is less readily shatterable than said shatterable front wall, said side wall joining said front and rear walls;

a drug-holding area between said walls adapted to hold a dosage of liquid drugs, the drug being injected into the target upon impact; and

wherein said drug-holding area contains a dosae of an incapacitating drug and a quantity of suitable means for forcing said drug against the target when the front end shatters on impact with the target.

2. A hypodermic projectile as set forth in claim 1 wherein said drug holding area contains a solvent along with said incapacitating drug and said means for forcing said drug against the target;

and wherein said means for forcing the drug against the target comprises compressed gas.

3. A hypodermic projectile as set forth in claim 1 wherein the drug holding area contains a quantity of dimethyl sulfoxide along with said incapacitating drug and said means for forcing the drug against the target, and wherein said incapacitating drug is an hypnotic drug and said means for forcing the drug against the target comprises compressed inert gas.

4. A hypodermic projectile as set forth in claim 3 in combintion with a shell casing, said shell casing having a wall at one end and an opening at the other end, said projectile being removably secured within said shell casing whereby said shatterable front end is disposed at said opening of the shell casng;

and an explosive charge contained between said rear wall of the projectile and said wall at one end of the shell casing.

5. A hypodermic projectile adapted to inject a liquid drug into an animal or human target upon impact therewith comprising:

a hollow body having a readily shatterable front wall, and a rear wall;

a side wall which is less readily shatterable than the shatterable front wall, said side wall joining the front and rear walls;

a junction seam between the front wall and the side wall, said seam having a jagged configuration and adapted to form sharp cutting edges when the front wall shatters on contact with a target; and

a drug-holding area between said walls adapted to hold a dosage of liquid drug, the drug being injected into the target upon impact.
