Puncturing system
First Claim
1. A puncturing device, comprising:
- a housing;
a puncture element;
a puncture element drive disposed in the housing and adapted to move the puncture element relative to the housing in a puncturing direction;
a press-on part configured to be pressed onto a body part in which a puncture wound is to be generated and having an opening through which the puncture element extends to create the puncture wound during a puncture movement, the press-on part being rigidly connected and fixed to the puncture element drive, wherein the press-on part and the puncture element drive move together as a unit relative to the housing when the press-on part is pressed onto the body part, whereby puncturing depth of the puncture element relative to the press-on part is not affected by movement of the press-on part relative to the housing; and
a pressure sensor for determining whether pressure exerted on the press-on part meets or exceeds a defined minimum value, the pressure sensor comprising a spring element against a spring force of which the press-on part is movable relative to the housing opposite the puncturing direction.

Abstract
Disclosed is a puncturing system for generating a puncture wound for obtaining a sample of a body fluid, comprising a press-on part to be pressed onto a body part in which a puncture wound is to be generated, a trigger, by the actuation of which a user can trigger a puncturing motion of a puncturing element after the press-on part is pressed on, and a testing facility for determining at least one test parameter on which a sample-obtaining probability depends. A securing facility is also provided that, in a locked state, locks the trigger such that no puncturing motion can be triggered, and, in a triggering state, releases the trigger such that a puncturing motion can be triggered by actuation thereof, whereby the securing facility is transitioned from the locked state to the triggering state by the testing facility when the test parameter determined by the testing facility meets defined minimum requirements. A signaling facility is also provided for signaling a transition of the securing facility to the triggering state and/or for signaling that the securing facility is in the triggering state. Also disclosed is a method for preparing a puncturing system for generating a puncture wound.

15. A puncturing device, comprising:
-
a housing; a puncture element; a puncture element drive disposed in the housing and adapted to move the puncture element relative to the housing in a puncturing direction; a one-piece press-on part configured to be pressed onto a body part in which a puncture wound is to be generated and having an opening through which the puncture element extends to create the puncture wound during a puncture movement, the press-on part being rigidly connected and fixed to the puncture element drive, wherein the press-on part and the puncture element drive move together as a unit relative to the housing when the press-on part is pressed onto the body part, whereby puncturing depth of the puncture element relative to the press-on part is not affected by movement of the press-on part relative to the housing; and a pressure sensor for determining whether pressure exerted on the press-on part meets or exceeds a defined minimum value, the pressure sensor comprising a spring element against a spring force of which the press-on part is movable relative to the housing opposite the puncturing direction.

16. A puncturing device, comprising:
-
a housing; a puncture element; a puncture element drive disposed in the housing and adapted to move the puncture element relative to the housing in a puncturing direction; a press-on part configured to be pressed onto a body part in which a puncture wound is to be generated and having an opening through which the puncture element extends to create the puncture wound during a puncture movement, the press-on part being rigidly connected to the puncture element drive, wherein the press-on part and the puncture element drive move together as a unit relative to the housing when the press-on part is pressed onto the body part, whereby puncturing depth of the puncture element relative to the press-on part is not affected by movement of the press-on part relative to the housing; and a pressure sensor for determining whether pressure exerted on the press-on part meets or exceeds a defined minimum value, the pressure sensor comprising a spring element against a spring force of which the press-on part is movable relative to the housing opposite the puncturing direction; and a trigger which can be manually actuated to cause the puncture movement after the press-on part is pressed, the trigger being separately actuable by a user from the movement of the press-on part.
