The present invention concerns a tape magazine especially for a hand-held device for analyzing a body fluid with a test tape that can be unwound from a storage unit and wound onto a waste unit where the waste unit can be driven in order to wind forward the test tape. The invention provides that a lock which keeps the test tape under tension is integrated in the tape magazine at least on the storage unit. The present invention also concerns a hand-held device with such a tape magazine. The present invention also concerns a hand-held device with a mechanical drive for the test tape and a disposable hand-held device with polymer-based electronic components.

The invention relates to a test element as a single-use article for examining a body fluid, comprising a lancing member that can be inserted into a body part, a collecting area configured thereon for body fluid obtained by the lancing and at least one light guide for an optical measurement in the collecting area. The collecting area is formed by a collection recess of the lancing member which extends in the lancing direction and the light guide is integrated into the lancing member such that it is secure against displacement and the distal end thereof is arranged in a proximal measurement zone of the collection recess.

The invention concerns a control device for a medical test system which has a lancing element that can be inserted into body tissue to collect body fluid and a lancing drive for the lancing element. A sensor element for body fluid is arranged on the lancing element and a control unit is coupled to the sensor element for detecting a fault when collecting body fluid. In order to improve the success rate, the control unit actuates the lancing drive for an automatic puncture repetition in less than 1 second when a fault, e.g., inadequate wetting of a detection field, occurs.

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.

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 of the defined residual puncturing depth (dr), with reference to the collecting phase.
摘要:
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.

The present invention generally relates to a system for sampling body fluids. In particular, the system has an implantable catheter for introduction into a tissue, a pump for transporting a volume of the body fluid out of the catheter, a volume determination unit for determining the volume of fluid and a control means for controlling the pump means based on the determined volume of body fluid.
