Abstract
A single-use lancet device is provided for drawing capillary blood samples. The device includes a body having an upper portion and a lower portion and a trigger carried by the upper portion of the body. The trigger is movable between a first raised position wherein the device is cocked and a second depressed position wherein the device is fired. A needle assembly is provided which is movable between a cocked position and a striking position. A free-floating drive spring is provided for moving the needle assembly from its cocked position to its striking position. A bounceback spring is integrally molded with the needle assembly and includes a pair of generally V-shaped spring arms. A trigger bar has a first position wherein it holds the needle assembly in its cocked position, and the trigger bar has a second position wherein it allows the needle assembly to move to its striking position as the drive spring expands. The trigger carries a pair of guillotine-type blades which sever the trigger bar and thereby releases the needle assembly from its cocked position. Alternate trigger bars are provided which may be deformed rather than severed. The device is also capable of assembly by automatic equipment. The device is incapable of a second use because of the deformation or severing of the trigger bar.
