Abstract:
PROBLEM TO BE SOLVED: To monitor whether an analysis region of a test element is positioned in an analysis position in a test element receptacle relative to the analysis unit. SOLUTION: The monitoring includes a step of irradiating the analysis region with light from at least one light source, a step of detecting light scattered or reflected at the analysis region by a detector for obtaining detection signals, and a step of evaluating the detection signals by an evaluation unit. In this case, delimitation of a light-transmissive region arranged between the test element and the detector is effected by a delimiting element having a light-opaque region.

Abstract:
PROBLEM TO BE SOLVED: To contain a maximum number of test strips protected from moisture in a test strip magazine which is exchangeable in an analyzer of mobile type. SOLUTION: The analyzer of mobile type, is provided with an interior delimited by a housing, and a magazine for holding a test element. The transporting device in the analyzer is provided for transporting the test element from a first position in the magazine to a second position which is at least partially outside of the magazine and positions in the housing, the transportation of the test element takes place in the two movements. The test element is moved to a presentation position by using a rotary device from the magazine which stores the test element in the storage position. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a handheld analyzer for testing a sample for a medically significant component, and a method for causing the handheld analyzer to operate in such a way as to reduce the possibility of malfunctions or operating errors. SOLUTION: This analyzer comprises a test unit 20 which detects the correct positioning of analytical consumable means 10 in a conveyance pathway. The test unit has both an electric switch 21 which mechanically senses the positioning of the analytical consumable means and an optical sensor 30 which optically senses the positioning of the analytical consumable means 10 on the conveyance pathway. The handheld analyzer 1 is controlled as a result of a comparison of the signals of the electric switch and the optical sensor. Employing this method reduces malfunctions or operating errors associated therewith. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an analysis system including an analysis unit for analyzing a content in a sample, a detection unit for detecting a signal, and a test element for holding the sample thereon. SOLUTION: This analysis system comprises a test element holder 19 to which the test element 5 can be reversibly introduced and in which it can be positioned relative to the analysis unit and the detection unit. The test element holder 19 contains at least one guide element 20 which is suitable for laterally guiding the test sample 5, so that the test element 5 in the test element holder 19 is held and guided on an outer region 23, and the test element 5 inserted into the test element holder 19 remains in a state where an inner region 24 including a sample application site 10 is exposed.

Abstract:
The invention relates to the field of analysis systems, in which a sample analysis is carried out using test strips. According to the invention, the analysis system comprises a transport unit (1), which is driven by piezo-active elements (2). The transport unit (1) permits the direct or indirect transport of test strips in such a way that analysis methods can be wholly or partly automated. The invention also relates to a transport unit for transporting a test strip (15), said unit being controlled by an optical detector that detects the test element (15) in the system.
Abstract:
The invention relates to an analysis system for analysing a sample on an analytical test element (16), said system comprising: a measuring module (13) for performing measurements of a sample on the analytical test element (16), an optical module (1, 25) comprising a lens (2, 26, 27), and a diaphragm (3, 21) for focussing the light. The lenses (2, 26, 27) and the diaphragm (3, 21) of the optical module (1, 25) are combined to form a multi-component injection-moulded part (23) embodied as a single component.
Abstract:
The invention concerns a method and a device for hematocrit correction in connection with a glucose measurement, where the following measures are proposed: - determining by means of a reference instrument (34), such as a laboratory analyser, a hematocrit reference value of a reference blood sample taken from a specific user, - applying a fresh blood sample of said user on a disposable analytical test element (12), - measuring the glucose value of the fresh blood sample by single use of said test element (12) in the glucose meter (10), - determining a hematocrit correction value using at least the hematocrit reference value, - adjusting the measured glucose value using the hematocrit correction value to receive an adjusted glucose value.
Abstract:
The invention relates to the field of analytical systems in which a sample i s analysed using test elements. According to the invention the analytical system comprises a transport unit (1) which is driven by piezoactive elements (2). The transpor t unit (1) enables a direct or indirect transport of the test elements thus enabling a complete or partial automation of analytical methods. Furthermore the invention encompasses a transport unit for transporting a test element (15) which according to the invention is controlled by an optical detector which detects the test element (15) in the system.
