Abstract

An automatic retractable lancet assembly includes a housing with a sharp-pointed lancet movably mounted therein. A depressible plunger and slide mechanism actuates the movement of the lancet outwardly from the housing. After this outward movement is completed, the actuator elements become dissociated from further movement of the lancet. Subsequently, the lancet is automatically retracted back inside the housing by virtue of a spring element.
