Abstract: Analysis system for automatically performing a skin prick analysis by pricking the skin for producing a sample of body liquid and detecting an analyte contained in the sample. The analysis system comprises a magazine with a plurality of compartments each containing a lancing element and an analysis element, and a reusable hand-held instrument having a drive assembly. The drive assembly is adapted for driving at least the following movements by manually generated mechanical force: a coupling movement by which one of the lancing elements is coupled to the drive assembly; a puncturing and sample collection movement of one of the lancing elements contained in the magazine and coupled to the drive assembly; and a remaganizing movement by which the test element is transported back into the compartment of the magazine.

Abstract: An actuator for driving a test element is disclosed. The test element can comprise a lancet for perforating the skin of a living organism. The actuator can comprise an engaging part for engaging and driving the test element in a lancing motion. The actuator can further comprise a lancing actuator and a lancing spring. The lancing actuator can bias the lancing spring by executing a forward movement and thereby can exert a biasing force on the engaging part. The actuator can further comprise a latch element. The latch element can be a force-sensitive latch element for exerting a retention force to hold back the engaging part. The retention force can counteract the biasing force. The latch element can release the engaging part when the biasing force exerted by the lancing actuator exceeds the retention force exerted by the latch element, thereby allowing the test element to perform the lancing motion.

Abstract: A microsampler puncturing system for collecting a body fluid from a body part is described, comprising a sample collection unit having a piercing element, and a puncturing instrument having a drive, by which a sample collection unit is movable on a movement path for piercing the piercing element into the skin of the body part and withdrawing it in a piercing and retraction movement, a setting device for setting the puncturing depth of the piercing wound to be generated, and a control device for controlling the piercing and retraction movement having the following sequentially executed movement phases: a forward phase, a retraction phase, and a collecting phase (S). The setting device is settable independently of the chronological mean <dr> of the defined residual puncturing depth (dr), with reference to the collecting phase.

Abstract: A test element magazine for a system for measuring the concentration of at least one constituent in a fluid sample is provided. The test element magazine comprises at least one test element in at least one chamber. The chamber is individually sealed by a sealing element. The test element comprises at least one active portion for contacting a skin portion of a patient and/or for contacting a fluid sample, wherein the test element further comprises at least one support body, wherein the support body is adapted for being engaged by an actuator. By a forward movement of the test element the support body of the test element applies a force to the sealing element, thereby forcing open the sealing of the chamber.

Abstract: A needleless hypodermic injector device comprises pyrotechnical means for generating gas sufficient for injecting a medication. The device includes a housing with a first chamber which contains a medication unit storing liquid medication to be injected and a second chamber which contains a propellant container, a propellant within the propellant container, and an igniter.
