Patent ID: 8382680

Claim:
A hand-held instrument for analyzing a body fluid, comprising: a housing having a housing opening to which a body part can be applied to generate a puncture wound; an analysis unit for analyzing a sample of a body fluid obtained at the puncture wound; a piercing unit disposed in the housing and including a lancet and a lancet drive for driving a puncture movement of the lancet; a transport unit for moving the piercing unit, including the lancet and lancet drive, relative to the housing between an operating position and a rest position, the piercing unit in the operating position being located at the housing opening such that a puncture wound can be generated by the lancet in the body part when the body part is pressed against the housing opening, the piercing unit being remote from the housing opening in the rest position, wherein the analysis unit can be moved relative to the housing into a position for receiving body fluid when the body part is pressed against the housing opening when the piercing unit is in the rest position; a functional mechanism connected to the piercing unit, the functional mechanism moving with the piercing unit between the operating position and the rest position; and an operating device for actuating the functional mechanism, wherein the piercing unit is movable relative to the operating device, the piercing unit being decoupled from the operating device in one of the operating position and the rest position and being coupled to the operating device in the other one of the operating position and the rest position.
