  • Patent number: 10278631
    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.

  • Publication number: 20190083706
    Abstract: Disclosed is a valve drive unit that has first and second SMA wires that can be alternatively activated. The valve drive unit further includes a pivoting member pivotably arranged around a pivoting member axis, the pivoting member including a valve driver arranged at a distance from the pivoting member axis. The first and second SMA wires are coupled to the pivoting member such that an activation of the first SMA wire causes the pivoting member to pivot into a first direction and an activation of the second SMA wire causes the pivoting member to pivot into a second direction, the second direction being opposite to the first direction. The valve driver is configured to releasably engage a valve driver coupler of a valve unit, such that, in the engaged state, a pivoting of the pivoting member is transmitted to the valve driver coupler via the valve driver.

  • Publication number: 20180160957
    Abstract: The invention concerns lancets with a lancet needle, the tip of the lancet needle being embedded in an elastic material. Furthermore the invention concerns lancets where the tip of the lancet needle is surrounded by a hollow body which partially consists of an elastic material that can be pierced by the tip of the lancet needle during the lancing process and which reseals the tip of the lancet needle in the hollow body when it is retracted. In addition the invention concerns a lancet magazine in which the lancets are accommodated in individual chambers, each chamber having an opening through which the tip of the lancet needle can pass, which is sealed by an elastic material. Finally the invention concerns the use of an elastic material as a component of a lancet or a lancet magazine to maintain the sterility of at least the tip of a lancet needle in the unused state and to hygienically protect at least the tip of a lancet needle in the used state.
