Abstract
A single-use lancet device is disclosed. The device comprises a housing with a compressible, flexible upper wall attached to the blunt end of a lancet, a lancet holder, and a perforable wall adjacent the tip of the lancet. Compressing the flexible upper wall drives the lancet tip through the perforable wall and into the body part. Spring tension developed in the flexible wall causes the lancet to retract into the housing after penetrating the body part. A stop mechanism then prevents repeated vertical movement of the lancet. The lancet is shielded before and after penetrating a finger or other body part.
