Patent number: 9439591Abstract: A system for determining an analyte in a body fluid includes a magazine comprising two partial magazines, one including chambers containing analysis elements having a sample contact zone and a reagent system containing a reagent, whose reaction with the body fluid results in a change of a variable, and another including chambers containing puncturing elements having a tip having a capillary channel, which forms a fluid connection between the tip and a sample transfer zone of the puncturing element. The system may also include an analysis instrument having a puncturing drive for driving a puncturing element on a movement path, a mounting for receiving the magazine such that one chamber of the magazine at a time is located in a functional position, in which a puncturing element in the chamber can be moved by the puncturing drive, and a measuring and evaluation apparatus for measuring the change of the variable.Type: GrantFiled: December 7, 2010Date of Patent: September 13, 2016Assignee: Roche Diabetes Care, Inc.Inventors: Stephan-Michael Frey, Hans List, Andrea Rittinghaus, Volker Zimmer, Guenter Ihle, Wolfgang Roedel

Patent number: 9186104Abstract: Instrument for producing a sample of body liquid for analysis by piercing the skin with a lancing element having a skin piercing tip. The instrument has a housing and a lancing drive for driving a lancing element connected thereto in a puncturing movement. A pressure ring surrounds a skin contact opening and is adapted for pressing against the skin such that the skin bulges into the opening for promoting expression of body fluid. The skin contact opening has an opening area corresponding to a circle with a diameter of at least 3 mm and at most 8 mm, and the instrument comprises a pressing force control device for controlling the pressing force between the pressure ring and the skin at the time of triggering the puncturing movement, to be at least 3 N and at most 8 N.Type: GrantFiled: April 29, 2013Date of Patent: November 17, 2015Assignee: Roche Diabetes Care, Inc.Inventors: Uwe Kraemer, Volker Zimmer, Wolfgang Roedel, Hans List, Stephan-Michael Frey, Christian Hoerauf, Paul Patel

Patent number: 9028426Abstract: The invention relates to a device for removing body fluid with a puncture element that can puncture the skin of a body part. The device includes a housing structure for body fluids obtained from the skin puncture and a puncture drive for a back and forth movement of the puncture element. The duration of withdrawal movement is longer than the duration of the forward movement. The puncture drive is designed to withdraw the puncture element in a first withdrawal phase of the withdrawal movement with a maximum withdrawal speed of more than 0.02 m/s. A second retraction phase follows the first retraction phase. Body fluid is collected during the second retraction phase, which has a duration of between 0.3 and 0.8 seconds and/or a retraction speed of between 0.6 and 2 mm/s.Type: GrantFiled: August 11, 2010Date of Patent: May 12, 2015Assignee: Roche Diagnostics Operations, Inc.Inventors: Hans List, Wolfgang Rödel, Christian Hörauf

Publication number: 20120197158Abstract: A handheld medical device for body fluid analysis such as to measure an analyte concentration, for example glucose, in a body fluid such as blood or interstitial fluid by a patient or caregiver. The device comprises a mechanical assembly having a transport unit for consumable analytical elements, a display unit, a sensor for analyzing a body fluid sample obtained by a lancet prick, a memory for storing a series of measurement results, a first actuating element, the actuation of which transfers the device into a first active state, activates the mechanical assembly and prepares a measurement. In the first active state, a measurement is started by the actuation of one of the actuating elements, and a second actuating element, the actuation of which transfers the device into a second active state. The display unit is switched on by the actuation of the second actuating element, without activating the mechanical assembly.Type: ApplicationFiled: August 3, 2011Publication date: August 2, 2012Inventor: Wolfgang Roedel
