Patent number: 8992750Abstract: Embodiments of the invention include a test strip with a sample chamber opening spanning the width of the test strip at the sampling end and including a portion of the lateral sides at that end. The chamber is vertically bounded by upper and lower substrate layers, horizontally bounded by the front face of a spacer layer, and open on the remaining sides. The test strip fills rapidly and requires small sample volumes. Both 1-up and 2-up manufacturing techniques for producing such test strips eliminate registration and alignment steps, and other techniques relating to the 2-up technique (simultaneously manufacturing test strips arranged in multiple columns) are also disclosed.Type: GrantFiled: July 2, 2013Date of Patent: March 31, 2015Assignee: Roche Diagnostics Operations, Inc.Inventors: Terry A. Beaty, Eric R. Diebold, Abner D. Joseph, Randall K. Riggles

Publication number: 20150076010Abstract: An analyte test sensor strip is disclosed having information coded thereon as well as a method of forming the same and conducting an analyte test using the analyte test sensor strip. Information relating to an attribute of the strip or batch/lot of strips may be coded based on resistance values pertaining to electrical aspects of the strip, such as a primary resistive element and a secondary resistive element, the secondary resistive element having one of a plurality of states defined by a location of a closed tap to form a unique resistive path for the secondary resistive element that includes a portion of the primary resistive element depending on the location of the closed tap. The states may be formed on the strip by a secondary processing step in the manufacture of the strip in which a plurality of taps are severed leaving only one tap in a closed state.Type: ApplicationFiled: November 17, 2014Publication date: March 19, 2015Inventors: John T. Austera, Terry A. Beaty, Abner D. Joseph, Nathan E. Manlove, Steven K. Moore, James L. Pauley, JR., Randall K. Riggles

Patent number: 8852124Abstract: A lancet-sampler system is configured to automatically remove a protective cover from a lancet and automatically unpack a test pad just prior to use. This minimizes the risk of injury and reduces the chance of cross-contamination between the lancet and the test pad. The lancet defines a capillary groove for drawing body fluid from the incision via capillary action and a sample transfer opening for collecting the fluid from the groove. A carrier tape is coupled to the lancet. The carrier tape includes a test pad for analyzing the fluid. The tape is folded around the test pad to form an airtight package. The test pad is located at a position to align with the sample transfer opening when the tape is unfolded. The protective cover covers a portion of the lancet, and when the tape is pulled, the protective cover is automatically pulled from the lancet.Type: GrantFiled: June 2, 2011Date of Patent: October 7, 2014Assignee: Roche Diagnostics Operations, Inc.Inventors: Steven N. Roe, Terry A. Beaty, Uwe Kraemer, Volker Zimmer

Publication number: 20130277235Abstract: Measurement systems and methods are disclosed for minimizing the effects created by a meter's output amplifier during electrochemical measurements. In the systems and methods, transition of an excitation potential applied between electrodes of a test strip is controlled so that it is at a sufficiently slow rate below a slew rate capability of the system (but still fast enough to minimally impact overall test time) to reduce variability in the test results. The methods and systems therefore use a transition having a ramp-shaped waveform, a sinusoidal-shaped waveform or an exponential-shaped waveform. Additionally, the excitation potential can be purposefully controlled by a processor, memory driven digital-to-analog converter or external circuitry at a rate sufficiently slow to make variations in the analog electronics slew rate insignificant for all sample types and test conditions.Type: ApplicationFiled: June 18, 2013Publication date: October 24, 2013Inventor: Terry A. Beaty

Patent number: 8540935Abstract: The present invention provides a test strip for measuring a concentration of an analyte of interest in a biological fluid, wherein the test strip may be encoded with information that can be read by a test meter into which the test strip is inserted. In one embodiment, a first test strip comprises: a first measurement electrode connectable to a test meter; a first trace loop with a first associated resistance, where the first trace loop is connectable to the test meter; and a second trace loop with a second associated resistance, where the second trace loop is connectable to the test meter. The test meter is adapted to: receive the first test strip; connect to the first measurement electrode, the first trace loop, and the second trace loop; and obtain a first resistance ratio by comparing the first and second associated resistances.Type: GrantFiled: May 21, 2012Date of Patent: September 24, 2013Assignee: Roche Diagnostics Operations, Inc.Inventors: Terry A.
