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

Patent number: 8231547Abstract: The present invention provides a puncturing system for withdrawing body fluid. The puncturing system comprises a disposable puncturing unit, which includes a needle element for piercing into skin and a puncturing depth reference element with a skin contact area. The system includes a puncturing instrument which has a puncturing drive, wherein the puncturing drive is coupled by a coupling mechanism to the puncturing unit for driving the needle element to a puncturing depth, the puncturing depth being determined by the distance in the piercing direction between the skin contact area and the position of the tip of the needle at a reversal point of the puncturing movement. The puncturing depth reference element is connected to the needle element such that the puncturing depth reference element moves with the needle element during at least part of the puncturing movement.Type: GrantFiled: September 1, 2007Date of Patent: July 31, 2012Assignee: Roche Diagnostics Operations, Inc.Inventors: Frank Deck, Ortrud Quarder, Thomas Weiss, Christian Hörauf, Michael Keil, Ahmet Konya, Herbert Harttig, Felix Baader, Hans List, Karl-Peter Ebert
