Abstract: A pain-alleviating device for injecting a hypodermic needle into human flesh comprising a tubular support for a syringe containing medicament and having an injection needle on one end and a plunger in the other end, the support having a canister on the end opposite that which receives the syringe and the canister comprising an annular chamber containing a solution of water and ethylene glycol or other suitable substance, such as NaCl, adapted to be frozen to as low as 0.degree. F., the needle of the syringe being disposed safely within the chamber of the canister until the syringe is projected farther into the tubular support sufficiently to project the needle through the outer end of the canister into a skin-chilled surface on a patient abutting the outer end of the canister.
