Patent number: 7160251Abstract: A system for measuring a glucose level in a blood sample includes a test strip and a meter. The test strip includes a sample chamber, a working electrode, a counter electrode, fill-detect electrodes, and an auto-on conductor. A reagent layer is disposed in the sample chamber. The auto-on conductor causes the meter to wake up and perform a test strip sequence when the test strip is inserted in the meter. The meter uses the working and counter electrodes to initially detect the blood sample in the sample chamber and uses the fill-detect electrodes to check that the blood sample has mixed with the reagent layer. The meter applies an assay voltage between the working and counter electrodes and measures the resulting current. The meter calculates the glucose level based on the measured current and calibration data saved in memory from a removable data storage device associated with the test strip.Type: GrantFiled: November 12, 2003Date of Patent: January 9, 2007Assignee: Home Diagnostics, Inc.Inventors: Gary T. Neel, Douglas E. Bell, T. Philip Wong

Patent number: 6979571Abstract: A test strip platform for a testing apparatus of the type using test strips, wherein the platform has a shroud defining a strip track for positioning an inserted strip over an optical aperture for making analytical determinations. The platform has a hood permanently mounted to the shroud for overlying the optical window and protecting the testing apparatus optics. The strip track has stabilizing members for holding the strip in testing position. The hood provides camming members for guiding the leading edge of an inserted strip into cooperative engagement with the stabilizing members for ensuring proper insertion of the strip.Type: GrantFiled: August 1, 2002Date of Patent: December 27, 2005Assignee: Home Diagnostics, Inc.Inventors: Brent Modzelewski, George Rounds

Patent number: 6964871Abstract: A system for measuring a glucose level in a blood sample includes a test strip and a meter. The test strip includes a sample chamber or other testing zone, a working electrode, a counter electrode, fill-detect electrodes, and an auto-on conductor. A reagent layer is disposed in the testing zone. The auto-on conductor causes the meter to wake up and perform a test strip sequence when the test strip is inserted in the meter. The meter uses the working and counter electrodes to initially detect the blood sample in the sample chamber and uses the fill-detect electrodes to check that the blood sample has mixed with the reagent layer. The meter applies an assay voltage between the working and counter electrodes and measures the resulting current. The meter calculates the glucose level based on the measured current and calibration data saved in memory from a removable data storage device associated with the test strip.Type: GrantFiled: January 26, 2004Date of Patent: November 15, 2005Assignee: Home Diagnostics, Inc.Inventors: Douglas E.

Publication number: 20050159768Abstract: An apparatus and method for lancing a surface provides an adjustable nozzle assembly that includes an interior nozzle, a collar, and an exterior nozzle with a surface that contacts the surface to be lanced. The exterior nozzle can then rotate relative to the interior nozzle and, thereby, vary the lancing depth of a lancet. The apparatus and method for lancing a surface also provides for a rearward body assembly that includes an interior tube, a lancet holder, an internal compression spring, a retainer, a rearward body, and an external compression spring. Longitudinal movement of the rearward body away from the interior tube can compress the interior compression spring and can, thereby, spring load the lancing device. The apparatus and method for assembling the adjustable nozzle assembly of the lancing device provides for an interior nozzle with an assembly groove and a ramped groove separated by a raised boss.Type: ApplicationFiled: January 15, 2004Publication date: July 21, 2005Applicant: Home Diagnostics, Inc.Inventors: David Boehm, Cameron Scott Casterline
