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.

Patent number: 8550295Abstract: The test strip containers accurately dispense one test strip for easy removal. One test strip container includes a slider with a slot that catches a single test strip therein from a stack positioned inside the container. The slider retaining the single test strip moves across the container while the single test strip rides along a ramp or track on the exterior of the container until the single test strip extends above the container. Another test strip container includes inner and outer cylinders. The inner cylinder defines an opening through which a test strip from a stack is dispensed and an external ramp or track. As the outer cylinder rotates about the inner cylinder, a recessed slot in the outer cylinder captures a single test strip, and continued rotation of the outer cylinder causes the test strip to ride along the ramp or track to extend above the cylinders for removal.Type: GrantFiled: February 22, 2010Date of Patent: October 8, 2013Assignee: Roche Diagnostics Operations, Inc.Inventor: Frank A. Chan

Patent number: 8454904Abstract: A biosensor container comprising a housing defining an internal glucose test strip compartment. The housing has an engagement portion for retaining a detachable means for storing data, and the means for storing data has data stored thereon specific to a batch of glucose test strips. At least one of the housing and the means for storing data includes at least one data reading element that is externally accessible when the means for storing data is retained by the engagement portion of the housing. The container includes various fail safe features to prevent mishandling and insure the user obtains the correct results. The housing includes means for connecting to the bG meter only when the means for storing data is retained by the housing. The housing further includes means for dispensing glucose test strips only when the housing is in either of an attached-to meter mode or a stand-alone mode.Type: GrantFiled: July 29, 2008Date of Patent: June 4, 2013Assignee: Roche Diagnostics Operations, Inc.Inventors: Nigel Surridge, Abner Joseph, Frank Chan, Martin Gerber, Matt Sauers

Publication number: 20130134159Abstract: A component for a storage container configured to receive vertically oriented articles. The component includes a tubular sidewall extending longitudinally from a base, and at least one spacer portion extending from an underside of the base and configured for engagement with an interior surface of a corresponding storage container. The component also includes at least one pair of retainer elements extending laterally from an inner surface of the tubular sidewall and inwardly into an interior region of the component, and with the retainer elements being oppositely oriented and configured to retain a vertically oriented article therebetween by frictional engagement with opposite longitudinal edges of the article, and wherein an insertion force for resilient deflection of the retainer elements during insertion of the article is less than a removal force for resilient deflection of the retainer elements during removal of the article.Type: ApplicationFiled: November 28, 2011Publication date: May 30, 2013Applicant: Roche Diagnostics Operations, Inc.Inventor: Frank A.

Patent number: 8328737Abstract: An integrated lancing test strip device includes a lancet configured to form an incision in tissue and a test strip coupled to the lancet for analyzing body fluid. A retention mechanism acts as a detent to hold the lancet in a static position relative to the test strip before forming the incision. The retention mechanism is configured to release the lancet for retracting the lancet relative to the test strip to reduce smearing of body fluid by the lancet during collection of the fluid with the test strip. In one form, the retention mechanism includes breakable tabs that are broken to release the lancet, and the lancet is retracted via translational movement. The retention mechanism in another form includes one or more dimples that release the lancet when the lancet is retracted via rotational motion. In a further form, the entire integrated device is rotated to collect fluid.Type: GrantFiled: September 8, 2011Date of Patent: December 11, 2012Assignee: Roche Diagnostics Operations, Inc.Inventors: Daniel Wong, Frank Chan

Publication number: 20120279172Abstract: A test strip container with an expandable insert, and methods of manufacturing and utilization thereof are disclosed. The container includes a housing defining a cavity, a lid, and a compressible insert removably mounted in the cavity. The compressible insert is expandable to retain a plurality of test strips in the cavity and to protect the test strips from environmental degradation.Type: ApplicationFiled: July 18, 2012Publication date: November 8, 2012Applicant: ROCHE DIAGNOSTICS OPERATIONS, INC.Inventors: Frank A.

Publication number: 20120226115Abstract: A meter system for analyzing body fluids includes a supply magazine for storing a stack of test elements, a meter for analyzing fluid samples, and a transport system for transporting test elements from the supply magazine to the meter. The test element in one embodiment includes a lancet integrated test element that has a lancet coupled to a test strip. The transport system is configured to minimize damage to the test element. In one form, the transport system includes a shuttle that slides the top-most test element from the stack onto a connection portion of the meter. In another form, the transport system includes a drum that rotates to transport test elements from the supply magazine to a testing position and, once used, to a waste magazine for disposal. In a further form, the transport system includes a disc that rotates to transport the test elements.Type: ApplicationFiled: May 14, 2012Publication date: September 6, 2012Inventor: Frank A. Chan

Patent number: 8158078Abstract: Embodiments of the present invention relate to a test strip container which provides easy access to test strips. The test strip container includes a lower housing, an upper housing, and a retaining member configured to releasably retain the test strips in a nested configuration. The nested configuration of the test strip container provides easy access to test strips by arranging the test strips so that they extend radially outward from the retaining member. The radial arrangement of the test strips operates to separate the test strips so that test strip users may easily select a single test strip from a plurality of test strips. Alternatively, the test strip container includes a lower housing, an upper housing, and a retaining member configured to releasably retain the test strips in a longitudinal configuration.Type: GrantFiled: October 21, 2011Date of Patent: April 17, 2012Assignee: Roche Diagnostics Operations, Inc.Inventors: Frank A.
