Patent number: 9599552Abstract: Devices and methods are provided for determining concentration of at least one analyte in a body fluid sample such as blood, especially a blood glucose concentration. In the methods, a test element is provided that has at least one reagent element configured so as to carry out at least one optically detectable detection reaction in the presence of the analyte. The body fluid sample is applied to the test element and a time course of at least one optical measurement variable of the reagent element is detected. At least one first time interval of the time course of the optical measurement variable is used to determine at least one disturbance variable value in the body fluid sample, in particular a concentration of a disturbance variable such as hematocrit. At least one second time interval of the time course is used to determine analyte concentration. The at least one disturbance variable value can be used to correct/compensate the analyte concentration.Type: GrantFiled: October 17, 2014Date of Patent: March 21, 2017Assignee: Roche Diabetes Care, Inc.Inventors: Susanne Baldus, Jochen Schulat, Sebastian Trick

Patent number: 8075496Abstract: The present invention provides an integrated measuring device that includes a blood collection system for collecting blood for diagnostic purposes. The blood collection system comprises an electric motor which provides energy for propelling a lancet. The blood collection system comprises a mechanical energy store in which the electric energy that is converted by the motor is stored in the form of mechanical energy. The use of a mechanical energy store allows the use of known mechanical drive elements. The blood collection system can also be electrically activated and is thus easy to use for the operator. The motor can also be coupled to another system component, such as a test strip or lancet drum, to operate it.Type: GrantFiled: January 27, 2007Date of Patent: December 13, 2011Assignee: Roche Diagnostics Operations, Inc.Inventors: Frank Deck, Joachim Doepper, Christian Hoerauf, Rudolf Pachl, Juergen Rasch-Menges, Joerg Scherer, Guenther Schmelzeisen-Redeker, Wilfried Schmid, Jochen Schulat, Bruno Thoes, Sven Winheim

Patent number: 7477404Abstract: The invention relates to embodiments of a method and a system for monitoring the correct positioning of a test element in a test element receptacle of an analysis unit, the test element carrying a sample to be analyzed by the analysis unit. Using a delimiting element, responsive signals resulting from irradiating an analysis region on the test element are effectively prevented from impinging upon a signal detector when the analysis region is in an incorrect position relative to the analysis unit. The delimiting element is provided with a light-opaque region and a light-transmissive region, and the light-opaque region is positioned such that responsive signals impinge upon it rather than the light-transmissive region when the analysis region is in an incorrect position.Type: GrantFiled: August 31, 2007Date of Patent: January 13, 2009Assignee: Roche Diagnostics Operations, Inc.Inventors: Jochen Schulat, Bernd Stenkamp, Guenter Schmelzeisen-Redeker, Wilfried Schmid, Dieter Meinecke, Kai Dickopf, Gertrud Albrecht, Andreas Menke, Bernhard Kern, Wolfgang Schwoebel, Stefan Kalveram
