Patent number: 12163909Abstract: The present disclosure refers to a sensor assembly for an IVD analyzer, the sensor comprising two opposite substrates with at least one fluidic conduit for receiving a sample. The electrodes of different types of electrochemical sensors are arranged on the two opposite substrates facing the at least one fluidic conduit for coming in contact with the sample and determining sample parameters, wherein the counter electrodes and the reference electrodes are formed on one substrate and the working electrodes are formed on the opposite substrate. This achieves optimal sensor-working conditions in terms of a homogeneous and symmetrical electric field density and enables a sensor assembly with simpler geometry and smaller size.Type: GrantFiled: May 31, 2023Date of Patent: December 10, 2024Assignee: ROCHE DIAGNOSTICS OPERATIONS, INC.Inventors: Sascha Lutz, Gregor Ocvirk, Christoph Boehm, Wolfgang Burkhardt, Miriam Ruf, Heinz Kontschieder

Method for monitoring an arrangement for determining the concentration of an analyte in a body fluid
Patent number: 7949477Abstract: The invention relates to a method for monitoring an arrangement for determining a concentration of an analyte in a body fluid. The determination of the concentration of the analyte by means of the arrangement involves a procedure in which the analyte from the body fluid passes through an interface and is transported in a stream of liquid into a flowmeter chamber, in which a measurement is carried out to determine the concentration of the analyte. The evaluation of the measurement takes place in a signal processor. The monitoring of the arrangement comprises the following steps: measurement of measured values of at least two correlated system parameters of the arrangement by means of a sensor system, and comparison of the measured values with limit values stored for each of the system parameters in a storage unit, to obtain a combination of at least two comparison results.Type: GrantFiled: December 23, 2008Date of Patent: May 24, 2011Assignee: Roche Diagnostics Operations, Inc.Inventors: Helmut Rinne, Gregor Ocvirk -
Publication number: 20110036153Abstract: The invention relates to a test element for the testing of a liquid sample. The test element includes a sample application area, a test field, a sample transport path extending between the sample application area and the test field and an actuator field including a electrically-conductive layer. The actuator field is switchable between a first state attracting the sample and a second state attracting the sample less by applying to the conductive layer an electric voltage that is different from an earth potential. The actuator field has a section that is arranged at about the same distance from the sample application area as the test field, measured along the sample transport path, such that a wetting of the test field by the sample can be controlled by applying a voltage to the actuator field.Type: ApplicationFiled: October 26, 2010Publication date: February 17, 2011Inventors: Gregor Ocvirk, Peter Kraemer, Wolfgang Fiedler
