Hand-held instrument for the analysis of body fluids
First Claim
1. 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.

Abstract
The present invention provides a hand-held analysis instrument for analyzing a body fluid. The instrument comprises a housing with a housing opening to which a body part, in particular, a finger, can be applied to generate a puncture wound, an analysis unit for analyzing a sample of a body fluid obtained at the puncture wound, and a piercing unit including a lancet and lancet drive for generating a puncture movement of the lancet. The piercing unit, including the lancet drive, is movable between an operating position and a rest position, the piercing unit being located at the housing opening in the operating position in such a manner that by means of the lancet a puncture wound can be generated in a body part pressed against the housing opening, and the piercing unit being remote from the housing opening in the rest position in such a manner that the space in front of the housing opening is free for the analysis unit, so that it can be moved into a position for receiving blood. An operating device is used for actuating a functional mechanism of the piercing unit. The piercing unit is decoupled from the operating device in one of its two positions and is coupled to the operating device in the other position.

15. A hand-held instrument for analyzing a body fluid, comprising:
-
a housing having an opening; an analysis unit for analyzing a body fluid sample; a piercing unit disposed in the housing and including a lancet drive for triggering a puncture and retraction movement of a lancet, the piercing unit, including the lancet and lancet drive, being moveable in the housing between an operating position and a 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; wherein, the analysis unit and piercing unit are alternatively movable into direct proximity to the opening. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
