Each of the optical detectors has a corresponding view in the receptacle and produces an electrical signal at a respective detector output in response to light from the corresponding view. The logic circuit includes logic inputs that are respectively coupled to the detector outputs and that produce an output logic signal corresponding to a logical combination of signals received at the logic inputs. In another aspect, respective detection signals are produced in response to light received from respective ones of multiple views of the test strip, and at least one output logic signal corresponding to a respective logical combination of the detection signals is generated.Type: GrantFiled: November 22, 2005Date of Patent: January 21, 2014Assignee: Alverix, Inc.Inventors: John F. Petrilla, Daniel B. Roitman

Patent number: 8621828Abstract: A lancet integrated test element tape includes a plurality of lancet integrated test elements. The lancet integrated test elements each include a lancet configured to form an incision in tissue and a test element configured to analyze body fluid from the incision in the tissue. A cartridge includes a supply compartment configured to store an unused section of the tape. The tape is folded within the supply compartment to limit damage to the lancet integrated test elements. The cartridge can further include a waste compartment in which a used section of the tape is stored. An indexing mechanism moves the tape between the supply and waste compartments.Type: GrantFiled: May 11, 2012Date of Patent: January 7, 2014Assignee: Roche Diagnostics Operations, Inc.Inventors: Frank A. Chan, Daniel Wong

Patent number: 8622929Abstract: A device (1410) for collecting a blood sample from an animal has a holder for holding a sampling media (1456), one or more spikes (1418) that first pass through the sampling media (1456) and penetrate into the flesh of the animal to create a puncture site to allow blood emerging from the site to be collected by the sampling media (1456) during and/or after penetration of the flesh. The device has a retainer (1427) for temporarily retaining the device (1410) on the animal whilst blood is collected and for allowing the device (1410) to be removed from the animal substantially intact for subsequent removal of the sampling media (1456) from the device.Type: GrantFiled: October 15, 2007Date of Patent: January 7, 2014Assignee: Noble House Group Pty. Ltd.Inventors: Craig Douglas Wilson, Ian Patrick Berrell, Craig Andrew Burke, Stephanie Norrell, Rita M Calnan

Publication number: 20130338537Abstract: A lancing device having a drive mechanism whereby unidirectional motion of the drive mechanism drives a lancet along an advancing portion and a retraction portion of a lancing stroke. A rotationally mounted crank member or a translationally mounted shuttle of the drive mechanism operate upon an associated linkage and/or a cam path portion of the lancet carrier to drive the carrier along the lancing stroke. Spring biased members optionally drive the mechanism and/or limit its extent of travel.Type: ApplicationFiled: June 18, 2013Publication date: December 19, 2013Inventors: Lauren R. PUSEY, Carmine L.

Publication number: 20130338536Abstract: An adjustable depth endcap for a lancing device includes a base member, a cover or cap member, and a dial member. The base member includes engagement features for movably mounting the dial thereto and engagement features for the attachment of the cap member. Actuation of the dial adjusts the positioning of an internal stop surface internal of the cap member without repositioning of the cap member such that the overall length of the lancing device remains constant regardless of the penetration depth setting, consistent depth control is provided, and utilization of space in the device housing for depth control features is not necessary.Type: ApplicationFiled: June 18, 2013Publication date: December 19, 2013Inventor: Kathleen HELLER

Patent number: 8608669Abstract: Lancets comprising a piercing element for puncturing the skin of a patient, a test region containing detection reagents for determining an analyte concentration of a body fluid sample, a capillary structure arranged in the piercing element for transporting a body fluid sample to the test region, and a sterile protection element, which encloses the tip of the piercing element. The capillary structure is blocked in a section surrounded by the sterile protection element. Also provided are methods for producing a lancet, comprising: producing a piercing element, which on the upper side has an upwardly open capillary structure; covering a section of the upper side of the piercing element and blocking the capillary channel in this section using a first material; covering a section of the underside using a second material; sterilizing the piercing element; and attaching a test region containing detection reagents to the piercing element.Type: GrantFiled: July 21, 2011Date of Patent: December 17, 2013Assignee: Roche Diagnostics Operations, Inc.Inventor: Herbert Harttig

Patent number: 8608668Abstract: A unique technique for maintaining the sterility and integrity of a lancet tip. One or more lancet tips are sandwiched between a first web and a second web of material to protect the sterility of the lancet tips. The first and second webs are heat fused together to form a structure that covers and encapsulates the lancet tips to protect the integrity of the lancet tips. The structure is cut to form individual protective caps to detachably cover each of the lancet tips.Type: GrantFiled: July 14, 2011Date of Patent: December 17, 2013Assignee: Roche Diagnostics Operations, Inc.Inventor: Frank A.
