  • Patent number: 8052926
    Abstract: 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.

  • Publication number: 20110238100
    Abstract: 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.

The lancet packet includes a sterility sheet enclosing a lancet to maintain the sterility of the lancet and prevent cross-contamination between the test strip and the lancet. The sterility sheet allows the lancet to be sterilized separately from the test strip. In one form, a firing mechanism has a blade that punctures and slits the sterility sheet during the firing cycle to reduce the chance of cross contamination between the lancet and the test strip prior to use. This allows an operator to load and subsequently remove an unused integrated lancing test strip without compromising the sterility of the lancet. The lancet includes an engagement opening in which the blade of the firing mechanism engages the lancet. The engagement opening is configured to reduce the chance of the blade becoming dull.

  • Publication number: 20110137206
    Abstract: A supply of lancets for a multi-use lancing device are carried by a tape and sequentially brought from a storage position to an activating position by advancing the tape around a bend. The lancets are non-circular in cross-section along their longitudinal lengths, and in their activating position they extend from the tape such that their sharp tips are available for lancing tissue. The carrying tape can be arranged in reel-to-reel format in a housing having a lancing opening. The lancets can be integral with the tape and activated to move the lancet through the lancing opening by moving the tape along its tape path or by translating a dedicated service loop of the tape. The lancets can also be independent from the tape and activated through the lancing opening by a separate lancing actuator. A test media can be included on the carrying tape and the housing can contain a sensor to yield an integrated lancing and testing device.
