  • Patent number: 9463274
    Abstract: A pump drive and a method thereof to dispense a liquid drug from a container having a plunger piston are disclosed. The pump drive provides a unidirectional clutch provided about a rotational axis which supports centrally a wheel. The clutch has an inner race operably connected to the plunger piston, wherein the clutch is configured to rotate both the inner race about the axis in unison with rotation of the wheel in only a first direction to advance the plunger piston, and to let the wheel rotate relative to the inner race about the axis in a second direction opposite to the first direction without advancing the piston plunger. The drive in one embodiment includes at least one shape memory alloy wire which when excited rotates the wheel in the first rotational direction to advance the piston plunger and dispense the liquid drug from the container.

  • Patent number: 9445756
    Abstract: An integrated lancing test strip includes a test strip and a lancet packet coupled to the test strip. 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. The sterility sheet gives the integrated strip a low profile, which is attractive for packaging multiple integrated strips in cassettes, drums, magazines or the like. In one form, the integrated strip is loaded in a meter that includes an adjustment mechanism that adjusts the position of the test strip relative to the skin being sampled. This allows the user to adjust the position of the test strip so as to not apply excessive pressure against skin, which could hamper bleeding from the incision in the skin.

  • Patent number: 9332938
    Abstract: A lancet enclosed in a sterility sheet forms a lancet packet to maintain the sterility of the lancet and prevent the lancet from unintentionally piercing the sterility sheet prior to lancet actuation. In one form, the lancet is immobilized by hot tack welding a portion of the sterility sheet to the lancet. Alternatively, portions of the sterility sheet are hot tack welded together through an opening in the lancet to limit movement of the lancet.

  • Patent number: 9179872
    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. In the lancets' 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.

  • Patent number: 9167992
    Abstract: Adjustment mechanisms are used in conjunction with integrated lancet test strips to adjust the position of the drive system, engagement system, or the drive coupling in a fixed stroke lancing system to thereby adjust the penetration depth of the lancet. In a variable drive stroke lancing system, the lancet penetration depth is adjusted by changing the stroke length of a drive system. The stroke length of a drive system is adjusted by rotating a cam or sliding a cam in a cam type drive system. In either the fixed or the variable drive stroke lancing system, the test strip and/or guidance foil of the integrated lancet test strip is immobilized while the lancet is actuated.

  • Patent number: 8852124
    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.

  • Patent number: 8814808
    Abstract: Body fluid sampling device comprising a skin-piercing element having a collection zone for receiving body fluid. In one embodiment, the collection zone includes a plurality of holes, e.g., 3 or more holes, or 50 to 100 holes. The hole size may be small, e.g., having a diameter of 0.01 to 0.5 mm. The holes may or may not extend through the lancet. In some embodiments, the holes have a depth of 50 to 500 ?m. In other embodiments, the collection zone is porous, or is a roughened area. The collection zone can take up a very small volume of body fluid, e.g., 3 to 10 nL, in a very short time period, e.g., less than 0.5 seconds. In other embodiments, the device further comprises a fluid receiving means spaced apart from the collection zone so that body fluid in the collection zone will not contact the fluid receiving means initially.
