A method for generating a module configured to determine concentration of an analyte in a sample of a body fluid is disclosed. The method includes providing a first set of measurement data derived from images of one or more test strips indicating a color transformation in response to a body fluid containing an analyte. The images can be recorded by multiple devices with differing cameras, software and/or hardware device configurations for image recording and image data processing. A neural network model can be generated in a machine learning process applying an artificial neural network and a module configured to determine concentration of an analyte in a second sample of a body fluid can be generated. Further, the present disclosure includes a system for generating the module as well as a method and a system for determining concentration of an analyte in a sample of a bodily fluid.

A test tape cassette is disclosed that includes a cassette housing and an analytical test tape. The test tape includes a plurality of analytical test elements, a spreading fabric for applying a body fluid, and an underlying reagent layer for detecting an analyte in the body fluid. The cassette housing has an application tip that has a guide path extending longitudinally to the test tape in an arched-shape and is uncurved at right angles thereto for supporting the test tape in a kink-free manner. The guide path has an apex area with a central opening that delimits a measuring window for an optical measurement on the test elements.

Test tape cassette and analytical test tape therefor

There is disclosed a tape cassette having a reeled-up carrier tape that carries at least one type of functional elements, namely test elements and/or puncturing elements, that are arranged at a distance from each other in a tape direction. The distances in the tape direction from a functional element to the next functional element of the same type change periodically in space at a period P. Moreover, there is disclosed a method for manufacture of a tape cassette of this type.

Tape cassette and method for the manufacture thereof

The invention concerns a diagnostic tape unit with a test tape that can be wound onto a spool which comprises a transport tape and a plurality of test elements mounted thereon, where the test elements have an analytical reagent layer, a carrier foil supporting the reagent layer and a piece of adhesive tape connecting the carrier foil with the transport tape, and where the front side of the reagent layer facing away from the carrier foil is designed for the application of a sample substance. According to the invention it is proposed that the test elements in combination with the light transmitting transport tape in each case form an optical multi-layer system for a rear-side reflection-photometric measurement of the reagent layer.

A blood glucose test instrument kit having modular component parts capable of being assembled into a plurality of different handheld blood glucose test instruments is disclosed. The kit comprises the combination of an interconnection platform adapted to connect to a collection of interoperable modules. The collection of interoperable modules including: a plurality of different measurement engine modules, at least one user interface module, at least one power supply module. A handheld blood glucose test instrument is assembled by the interconnection to the interconnection platform of at least one measurement engine module, at least one user interface module, and at least one power supply module. The inter-module communication among the modules connected thereto to achieve enhanced glucose test instrument reliability by effecting at least one reliability protocol selected from a group of reliability protocols.
