Patent number: 8066957Abstract: 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: December 23, 2009Date of Patent: November 29, 2011Assignee: Roche Diagnostics Operations, Inc.Inventors: Frank A. Chan, Chris Wiegel

Patent number: 8062233Abstract: 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: January 19, 2009Date of Patent: November 22, 2011Assignee: Roche Diagnostics Operations, Inc.Inventor: Frank A.

Publication number: 20110278321Abstract: A test strip container comprising a housing defining a cavity having a dispensing wall, a housing inlet, and a dispensing outlet is presented. The container may also comprise a lid mounted movably on the housing to define a primed position and an unprimed position therebetween. A cartridge may be provided within the cavity and holding a plurality of test strips. The cartridge may have a plunger entrance seal and a strip exit seal. A biasing member may be disposed within the cartridge urging the plurality of test strips towards the dispensing wall to be aligned with the dispensing outlet. A plunger may be provided, and oriented to open the plunger entrance seal through the housing inlet when the lid is in the primed position, and to urge a single test strip from the plurality of test strips through the strip exit seal of the cartridge and the dispensing outlet of the housing when the lid is transitioned from the primed position to the unprimed position.Type: ApplicationFiled: May 11, 2010Publication date: November 17, 2011Applicant: ROCHE DIAGNOSTICS OPERATIONS, INC.Inventors: Frank A.

Patent number: 8052926Abstract: An integrated disposable includes a test strip and a lancet packet coupled to the test strip. The lancet packet includes a sterility sheet enclosing at least a portion of a lancet to maintain the sterility of the lancet. The lancet packet and the sterility sheet, in particular, allow the lancet to be sterilized separately from the test strip. The lancet in one form is incorporated into a lancet tape that is sterilized in a continuous, reel-to-reel sterilization process. The lancet tape in one form is sterilized using an electron beam sterilization process. With electron beam sterilization, sterilization is enhanced by irradiating both sides of the tape with electron beams. Sterilization can adversely affect chemical reagents in the test strip. To alleviate this chemistry degradation issue, the lancet packet is attached to the test strip after the lancet is sterilized.Type: GrantFiled: July 25, 2008Date of Patent: November 8, 2011Assignee: Roche Diagnostics Operations, Inc.Inventors: Abner David Joseph, Frank A. Chan, Steven N. Roe

Patent number: 8025628Abstract: 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: February 22, 2010Date of Patent: September 27, 2011Assignee: Roche Diagnostics Operations, Inc.Inventors: Daniel Wong, Frank Chan

Publication number: 20110204079Abstract: 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: ApplicationFiled: February 22, 2010Publication date: August 25, 2011Inventor: Frank A. Chan

Publication number: 20110182785Abstract: A test strip container with a pop-up design which provides easy removal of test strips, and methods of manufacturing and utilization thereof are disclosed. The test strip container comprises a base, a lid, and an elevating platform which translates in a vertical direction upon opening of the test strip container. The test strips are arranged within the base such that they face radially inward and rest upon the elevating platform. Translation of the elevating platform causes the test strips resting upon the platform to translate upward in a perpendicular manner, such that they may be easily removed by test strip users.Type: ApplicationFiled: January 22, 2010Publication date: July 28, 2011Applicant: ROCHE DIAGNOSTICS OPERATIONS, INC.Inventor: Frank Chan
