The present invention concerns a tape magazine especially for a hand-held device for analysing 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 concerns a device for collecting body fluids which has at least one lancet comprising a lancet body with at least two tips of different lengths. The device is characterized in that it has a selection means with the aid of which only one tip is selected before the lancing. This selection means can have different functions and shapes. The selection means is used to select a tip from a plurality of lancet tips which have different lengths and make only this tip available for use in the lancing process. Since the various tips are attached to a lancet body, it is, for example, possible to use a bending element which bends one of the various tips out of the plane of the lancet body in order to provide only one lancet tip for use. This is especially preferable for lancet tips that are arranged linearly relative to one another.

An analysis system for determining an analyte of a body fluid comprises a test element and an analysis instrument having a measurement and evaluation unit. The test element has a sample application zone and two analysis zones and a reagent system, whose reaction with the analyte results in a detectable change characteristic for the desired analytical result. The measurement and evaluation unit comprises two analog measuring units, in each of which an analog measurement signal corresponding to one of the analysis zones is generated, two analog-digital converters for digitizing the analog measurement signal, a comparator unit for comparing control data values based on the digitized measurement signals, and a final processing unit, in which, if the determined deviation between the control data values of the digitized measurement signals is less than a predefined value, at least one of the control data values is allowed to pass for further processing into the desired analytical result.

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:
A method is presented for determining the concentration of an analyte in a liquid sample using a reagent system. The reaction of the sample with the reagent system results in a change of the quantity of a fluorophore, the quantity of the fluorophore correlating with the concentration of the analyte, a characteristic measurement variable for the quantity of the fluorophore being measured, and the concentration of the analyte being determined using an evaluation algorithm on the basis of the measurement variable. The reagent system is integrated in an analysis system and the fluorescence lifetime of the fluorophore is used in the ascertainment of the concentration of the analyte.
