Title: (EN) Test tape unit for blood tests
Abstract: front page image
(EN)

The present invention provides a test tape unit suitable for testing blood sugar. The test tape unit comprises an analytical test tape, a feed spool for unwinding unused test tape, a take-up spool for winding used test tape, and a tape guide to expose a section of test tape at a measuring site for receiving an application of body fluid. The tape guide has a flat support frame which stretches the test tape at the measuring site and forms the border of a measuring opening which is kept free from optical elements for producing an optical measurement.
