Abstract
A test tape unit with a flexible carrier tape that can be wound forwardly by a tape drive is provided. The carrier tape includes a plurality of analytical test fields for the application of body fluid that are each applied in an associated tape section. Each tape section has a plurality of position markers for different functional positions that can be scanned by means of a tape sensor and can thereby be individually identified by measured quantity.
Claims21
Test tape unit, comprising:
- a flexible carrier tape that can be wound forwardly by a tape drive on which carrier tape a plurality of analytical test fields are applied for the application of body fluid, wherein each test field is located on an associated tape section along with at least one check field that is separate from the test field, wherein each tape section has a plurality of position markers for different functional positions of said tape section that are configured to be individually identifiable as a measured quantity by a tape sensor, wherein at least one position marker is a check position marker and is separate from the check field assigned to the check position marker on each tape section, wherein identification of the check position marker by the tape sensor is configured to indicate the check field can be scanned for a functional check by a measuring unit that also is operable to measure the test field when the carrier tape is wound forwardly from the check field.
Test tape device comprising:
- a test tape unit including a flexible carrier tape, the carrier tape including a plurality of analytical test fields for the application of body fluid, wherein each test field is located on an associated tape section along with at least one check field that is separate from the test field, wherein each tape section has a plurality of position markers for different functional positions that are configured to be individually identifiable as a measured quantity, wherein at least one position marker is a check position marker and is separate from the check field assigned to the check position marker on each tape section;
- a tape drive for the test tape unit that can be exchanged as a consumable unit in the form of a tape cassette;
- a measuring unit configured to scan the check fields as a functional check and to scan the test fields in a measuring position;
- and
- a control device comprising a tape sensor configured to scan and identify the position markers to actuate the tape drive according to the position markers, wherein identification of the check position marker by the tape sensor is configured to indicate the check field is positioned for scanning as a functional check by the measuring unit.
