Abstract:
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.
Abstract:
The invention concerns a test tape device for analyzing a body fluid having a carrier tape (36), a plurality of lancing elements (12) arranged on the carrier tape (36) which are provided with a tip (40) that can puncture a body part and a collecting structure (44) that takes up the body fluid obtained during the puncture, and test fields (14) mounted on the carrier tape (36) each being associated with a lancing element (12) and can have body fluid applied thereto. According to the invention it is proposed that the lancing elements (12) are each movably attached to the carrier tape (36) by a coupling member (38) and that a used lancing element (12) can be brought into contact with a test field (14) by a transfer movement from a usage position distant from a test field (14) into a contact position so that body fluid can be transferred from the collecting structure (44) onto the test field (14).
Abstract:
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.
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 system comprising disposable medical devices and a packaging strip comprising a plurality of chambers containing the disposable medical devices. The strip is folded along breadthwise running fold lines to form a series of loops, each loop comprising opposing sections. The opposing sections of at least some of these loops are sealed to each other thus forming chambers between said sections. A cartridge contains such a packaging strip.
Abstract:
The invention relates to a piercing device for creating a puncture wound for collecting a sample of body fluid, comprising a rubber elastic pressure part to be pressed onto a body part from which a sample of body fluid is to be removed, and a piercing drive mechanism by means of which a piercing element inserted into the piercing device can be driven in a piercing movement. According to the invention, an electrical deformation sensor is provided for detecting an elastic deformation of the pressure part by means of an electrical and/or magnetic measurement.
Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
A test instrument for analyzing body fluids such as blood or urine. The instrument includes a wound test tape which can be transported from a storage space into a waste space by advancing the tap. The test tape has a plurality of test sections to which body fluid can be applied at a receiving position and also includes a measuring unit for detecting a constituent of the body fluid on an active test section. In order to carry out auxiliary instrument functions, in addition to the test sections, the test tape has one or more functional sections which can be brought into a functional position by advancing the tape.
