Patent number: 8251920Abstract: An apparatus for lancing skin and collecting a liquid sample. The apparatus having a housing with an outer periphery and a rotatable arm having a lance to puncture the skin. A sample collection area is attached to the arm. The arm of the apparatus rotates from a first position to a second position. As the arm rotates, the lance extends beyond the housing allowing the lance to contact the user's skin and create a lance site. As the arm continues to move to the second position, the lance is brought out of contact with the user's skin and back within the housing while the collection area is brought into position. When the arm is located in the second position, the collection area is in substantially the same location as the lance site on the user's skin.Type: GrantFiled: January 13, 2010Date of Patent: August 28, 2012Assignee: Bayer Healthcare LLCInventors: Mark S. Vreeke, Scott L. Hoover, Steven C. Charlton, Larry D. Johnson

Publication number: 20120031776Abstract: A biosensor system determines an analyte concentration of a biological sample using an electrochemical process without Cottrell decay. The biosensor system generates an output signal having a transient decay, where the output signal is not inversely proportional to the square root of the time. The transient decay is greater or less than the ?0.5 decay constant of a Cottrell decay. The transient decay may result from a relatively short incubation period, relatively small sample reservoir volumes, relatively small distances between electrode surfaces and the lid of the sensor strip, and/or relatively short excitations in relation to the average initial thickness of the reagent layer. The biosensor system determines the analyte concentration from the output signal having a transient decay.Type: ApplicationFiled: August 16, 2011Publication date: February 9, 2012Applicant: BAYER HEALTHCARE LLCInventors: Huan-Ping Wu, Steven C.
