A replaceable magazine for use in an analytic test instrument a plurality of analytic aids on a carrier tape. The analytic aids can be made available in an application position of the magazine by means of the carrier tape. The magazine has a supply reel for holding regions of the carrier tape with unused analytic aids and a take-up reel for holding regions of the carrier tape with used-up analytic aids. The carrier tape can be moved in a spooling direction from the supply reel to the take-up reel. The magazine has a rewind lock of the take-up reel. The magazine has a tape release device, which is configured to make available a take-up reel tape reserve of the carrier tape on the side of the application position facing the take-up reel. The take-up reel tape reserve enables a lifting movement of an analytic aid situated in the application position.

The present invention provides a puncturing system for withdrawing body fluid. The puncturing system comprises a disposable puncturing unit, which includes a needle element for piercing into skin and a puncturing depth reference element with a skin contact area. The system includes a puncturing instrument which has a puncturing drive, wherein the puncturing drive is coupled by a coupling mechanism to the puncturing unit for driving the needle element to a puncturing depth, the puncturing depth being determined by the distance in the piercing direction between the skin contact area and the position of the tip of the needle at a reversal point of the puncturing movement. The puncturing depth reference element is connected to the needle element such that the puncturing depth reference element moves with the needle element during at least part of the puncturing movement. The puncturing depth reference element has a defined longitudinal position in the piercing direction relative to the needle element at least at the reversal point of the puncturing movement.

A diagnostic test tape for liquid samples is provided comprising a flexible transport tape and a plurality of test fields applied to the transport tape that are distributed in the longitudinal direction of the tape, where said test fields comprise a detection layer and a spreading net spanning the detection layer for a planar uptake of liquid sample, wherein the spreading net is formed from a lattice-like fabric comprising fabric threads that cross at right angles. In order to prevent the fabric from arching up under tape tension it is proposed that the fabric is oriented obliquely to the transport tape such that all fabric threads run obliquely to the longitudinal direction of the tape.

A supply of lancets for a multi-use lancing device are carried by a tape and sequentially brought from a storage position to an activating position by advancing the tape around a bend. The lancets are non-circular in cross-section along their longitudinal lengths, and in their activating position they extend from the tape such that their sharp tips are available for lancing tissue. The carrying tape can be arranged in reel-to-reel format in a housing having a lancing opening. The lancets can be integral with the tape and activated to move the lancet through the lancing opening by moving the tape along its tape path or by translating a dedicated service loop of the tape. The lancets can also be independent from the tape and activated through the lancing opening by a separate lancing actuator. A test media can be included on the carrying tape and the housing can contain a sensor to yield an integrated lancing and testing device.

A lancet device for generating a puncture wound in a skin surface, comprising a housing, in which a lancet can be moved on a puncturing path, a lancet drive with a drive rotor that can be driven by a drive spring, a lancet coupling mechanism that transforms a rotational motion of the drive rotor into a puncturing and returning motion of the lancet during a working cycle of the lancet drive, a reference element that is mobile relative to the lancet and relative to the housing and is fixed in a defined position relative to the lancet drive during the puncturing and rests against the surface of the skin with a contact surface thereof such that a puncture wound with a reproducible puncturing depth is generated by the puncturing motion, and a reference element coupling mechanism that is coupled to the lancet drive in order to move the reference element. The invention further relates to a suitable lancet drive assembly for a lancet device of this type.

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.

An infusion device with safeguards for protecting a patient from inappropriate infusion during a malfunction comprises a pump, an electronic controller for controlling the pump, and a mechanical stop facility for stopping the pump by mechanically blocking pump motion. The stop facility periodically requires resetting by the controller to continue infusion.
摘要:
Catheter for monitoring the concentration of an analyte in a body fluid having an implantable distal area (7) for the uptake of body fluids and a proximal area (8) with an outlet opening (14), wherein the catheter comprises a catheter casing (1) having microopenings which are permeable to at least part of the body fluid and at least partially hold back corpuscular components, and a catheter core (2) which is located in the catheter casing (1). The catheter core preferably has a microstructure on its peripheral surface and/or the catheter casing has a microstructure on its inner wall which form a hollow space between the catheter core and catheter casing. Moreover the invention concerns a method for the manufacture of such a catheter.

The present invention provides a lancet system having a lancet tip, a lancet body, and an outer body or housing which surrounds the lancet tip and in which the lancet tip is movable. The outer body or housing comprises deformable material which can be pierced by the lancet tip during a puncture operation to produce an outlet opening. The outlet opening can be widened during the puncture operation by a thickened or widened portion of the lancet body that at least partially protrudes through the opening. Other embodiments of the present invention include a pricking aid and/or lancet system provided as a magazine for holding a plurality of lancets.
