Abstract: The present invention discloses a bone fixation device composed of two separate connectable sections: a compression device and an elongated member. The compression device is further composed of four interacting elements: a hollow, elongated body; a flexible compression wire; at least two compression blades and a hollow cylinder. The elongated member may be adapted to accept shims. The present invention also discloses a bone alignment device composed of: two adjustable circular members; a tubular, longitudinally extending member connecting the two circular members; at least two longitudinally extending connectors also connecting the two circular members and at least one adjustable bone alignment means attached to each connector for applying pressure to the limb containing the fractured bone. The present invention also discloses a system for using the bone alignment device and bone fixation device of the present invention together to align and fix a broken bone.

Abstract: A rectangular hypodermic syringe with a needle that can not be re-used once a nonlinear needle has been moved to a needle protecting retracted position includes a rectangular cylinder; a rectangular plunger for displacing the fluid within the cylinder; a rectangular needle guard, having an interior chamber, demountably attached to the rectangular cylinder; an elongate needle assembly, having a nonlinear needle, slidably mounted within the interior chamber of said needle guard; and means for fluidly coupling said cylinder to said needle when the needle assembly is in the extended position and for fluidly separating the cylinder from the needle when the needle assembly is in the retracted position. Lock means locks the needle assembly in the needle exposing extended position. Release means unlocks the needle assembly allowing a coil spring to move the needle assembly to the needle protecting retracted position.
