Abstract

An injection clamp for lifting and holding skin on an upper arm comprising: a pair of mating parallel elongated jaw members; a pair of mating arm members hinged together at one end, each arm member having a hinge end portion which carries an elongate jaw member extending laterally therefrom, each arm member having a rounded central portion adapted to extend around one side of the upper arm, and a spring end portion, said spring end portion being the end of the arm member opposite the hinge end; and, tension spring extending between the spring end portions of the pair of mating arm members is disclosed. The unique design of the clamp allows one to single handedly slide the clamp over the upper arm, open the spring end portion thereof with one'"'"'s fingers, and then while pulling the elongate jaw members towards the arm--allow the spring end portion to close so that the skin is pinched between the elongate jaw members. The mechanical leverage inherent in the design results in a much smaller force being required to open the arm members than is exerted between the jaw members. The squeezed skin is wholly exposed and unobstructed by the clamp for injection.

Claims

1. An injection clamp for lifting and holding skin on an upper arm comprising:

a pair of mating parallel elongated jaw members;

a pair of mating arm members hinged together at one end, each arm member having a hinge end portion which carries one of the elongated jaw members extending laterally therefrom, each arm member having a rounded central portion adapted to extend around one side of the upper arm, and a spring end portion, said spring end portion being the end of the arm member opposite the hinge end; and

,

tension means extending between the spring end portions of the pair of mating arm members.

2. A clamp as in claim 1 wherein the tension means is a helical spring.

3. A clamp as in claim 2 wherein the spring end portion comprises a straight elongate portion having an inner end carried by the central portion and an outer end to which one end of the helical spring is connected.

4. A clamp as in claim 3 wherein the mating arm members are generally planar.

5. A clamp as in claim 4 wherein the hinge end portion of one arm member is offset so that the mating arm members generally move in the same plane.

6. A clamp as in claim 4 wherein the hinge end portions of both arm members are offset an equal amount so that the mating arm members generally move in the same plane.

7. A clamp as in claim 4 wherein the hinge end portion of each arm member is provided with a lateral hole adapted to receive and carry the elongate jaw member which laterally extends therefrom.

8. A clamp as in claim 7 wherein the lateral hole is elongated and the elongate jaw members are held to the arm members by a screw so that the spacing between the elongate jaw members may be adjusted.

9. A clamp as in claim 8 wherein the elongate jaw member has a mounting base and a perpendicular elongate jaw portion.

10. A clamp as in claim 7 wherein the arm members and the jaw members are fabricated from a metal plate.

11. A clamp as in claim 10 further comprising a spring cover.
