Problems solved by technology

The transfer of multiple functions to one component creates more contradictory requirements and causes the realization of the main functionality (packaging and design performance) to become more difficult, while other functional requirements - mechanical reinforcement of system structural components and precise positioning - only insufficiently implemented

Embodiment Construction

[0025] The blood glucose testing device 10 depicted in the figure in the form of a hand-held device can use a cassette 12 as an analytical consumable for performing multiple self-tests using system samples collected by the patient himself in the field.

[0026] figure 1 Blood glucose testing device 10 is shown with lid 14 of housing 16 opened to release cartridge compartment 18 . The cassette compartment 18 is defined on the underside by a platform 20 which forms a device base for the defined fixation of the optical measuring unit 22 and for the storage of the magnetic tape cassette 12 in position relative to the measuring unit. To this end further positioning elements 24 are arranged on the platform 20 and on the cassette 12 which, together with the spring means 26, ensure exact positioning and easy handling when changing the cassette.

[0027] The spring device 26 comprises a cover leaf 28 which is punched out of sheet metal and pre-bent in an inner protruding annular confi...

Abstract

The test system has a diagnostic tape cartridge, which comprises a winding analytical test tape for identifying an analyte. The tape cartridge is detachably fixed on a platform (20) mounted in a device housing (16) by positioning elements (24). A measuring unit (22) is firmly fixed on the platform or brought in engagement with the platform.

Description

technical field [0001] The present invention relates to a test system, in particular for performing blood glucose tests, the test system having a diagnostic cassette and a test device, wherein the diagnostic cassette comprises a reelable analytical test strip for analyte testing and a case containing the test strip Housing, the test device has a device housing for loading and unloading the cassette and a preferably optical measurement unit for obtaining an analyte on the test strip. Background technique [0002] For the self-diagnosis of diabetics, individual test strips have hitherto been practically used, after application of a small sample volume a photometric (photometrisch) examination has been used in order to determine the glucose content in the blood sample as accurately and reliably as possible. In this case, the measuring strip is usually secured during the measurement by means of a holding structure which is part of the housing of the handheld device. In this way...
