  • Patent number: 7244264
    Abstract: An integrated lancing test strip includes a pair of blade members that each have a lancing tip that are configured to lance skin. A pair of spacer members connect the blade members together such that the blade members define an internal capillary. A test strip is positioned along the internal capillary, and the test strip is configured to test analyte levels in the bodily fluid. During use, the lancing tips form one or more incisions in the skin. The fluid from the incisions is drawn via capillary action through the internal capillary and onto the test strip.

  • Patent number: 7235056
    Abstract: A device for sampling body fluid includes a housing having a sleeve at a forward end thereof which is displaceable in response to being pressed against a user's skin to trigger the firing of a lancet. After the lancet is removed from the incision, the sleeve is repeatedly pressed against the skin to depress a ring of body tissue in surrounding relationship to the incision to express body fluid outwardly through the incision. A pusher member is then actuated to push a capillary tube through a front end of the housing for drawing-in body fluid. The lancet is a disposable lancet which includes a body supporting a skin-lancing member and the capillary tube. The disposable lancet passes through an upper end of a lancet carrier when being installed or removed. The device cannot be armed until the disposable lancet is installed in the housing, because the capillary tube functions to push a safety device to a non-safety position.

  • Patent number: 7163515
    Abstract: This disclosure describes a device for obtaining a blood sample from an intruder at a crime scene to be later analyzed for DNA. A projectile containing a blood-extracting needle for penetrating the skin of said intruder is mounted through a protective chamber and connected to a blood reservoir in the chamber interior. A vacuum is held in both the reservoir and the chamber. The chamber vacuum is released by forward movement of the chamber as it slides within a casing following further penetration of the needle. The vacuum release acts to reduce the ambient pressure within the forward portion of the casing, thus assisting in propelling the needle into the intruder. As the needle reaches maximum extension, a loaded spring within the casing is released, propelling the needle and reservoir away from the intruder.

  • Patent number: 7087068
    Abstract: A skin pricker has a barrel (1,11) in which a hammer (2,29) released by a trigger mechanism (32,34) can be shot forwards by a compressed spring (3,38) to impact on a lancet (24) and momentarily project its tip. The rear end of the spring acts against a barrier (4,39) adjustable axially of the barrel, so that the spring can be more or less compressed before release, causing the hammer to act with greater or lesser force on the lancet. The barrier (4,39) may have projections (6,8,42) that engage in skew slots (7,9,43) in the barrel, so that rotation of the barrier axially adjusts it. A sleeve (44) over the rear part of the barrel instrumental in priming the device may co-operate with the projections and be rotatable to set the desired spring force.

  • Patent number: 7077828
    Abstract: A device for withdrawing blood for diagnostic purposes including a lancet and a lancet drive having a loadable elastic drive spring provided within an elongated housing. A relaxing motion of the drive spring is converted into a puncturing motion to move the lancet at high speed in a puncturing direction until its tip exits out of an opening of the housing. The device includes a transmission in the housing that has an input side that transforms the motion of a loading element along a linear loading path into a rotational motion of a lancet drive rotor to load the lancet drive rotor by tensioning the drive spring. When the lancet drive is triggered, the output side of the transmission converts a rotational motion of the lancet drive rotor, driven by the drive spring, into the puncturing motion in a direction along the main axis.

  • Patent number: 6997936
    Abstract: A skin pricker has a housing (1) for a lancet (5) which, when released from a rearward cocked position, is propelled forwards by a spring momentarily to project its tip (3).

If the lancet (5) is then pushed back, the peg (12) cannot re-enter the slot (10): instead it wedges the lancet sideways and, before it can be re-cocked, traps the lancet behind an abutment (13) ensuring that the tip (3) cannot be re-exposed.

  • Patent number: 6866641
    Abstract: A skin pricker for blood sampling has a barrel housing a lancet which can be pushed back against a spring to a primed condition, by an elongate cap over its needle tip there to be held by a trigger. The cap (4) is removed by twist and pull action. The lancet body has integrally formed spring arms extending rearwardly and alongside, and when the lancet is fired these are momentarily flexed inwardly as their tips snap past abutments within the barrel. These act as ratchets, providing a first defence against re-priming of the pricker. If that first defence is overcome by a substantial rearward force on the lancet, the spring arms rearward pointing V's which wedge between the abutments and the lancet body. The cap may have a weakness leaving it rigid enough for the initial priming but which causes it to buckle if used to try to overcome the ratchet.

  • Publication number: 20040267300
    Abstract: A lancing device is adapted for use in firing a lancet into the skin of a patient to acquire a blood sample and, subsequent thereto, calculating and displaying the concentration of glucose in the acquired sample. In one embodiment, the device comprises a lancet and a torsion spring coupled to the lancet through a lancet holder. The torsion spring includes inner, middle and outer rings which are concentrically configured, a plurality of activation spring arms which connect the middle and outer rings and a plurality of return spring arms which connect the inner and middle rings. In use, the plurality of activation and return spring arms can be independently transformed between energized and de-energized states using a single, button-shaped mechanism. Rotation of the mechanism is used to energize the activation and return spring arms.

  • Publication number: 20040267299
    Abstract: A lancing device for drawing a body fluid sample from the skin that comprises a body portion, an endcap, a lancet and a vibration member. The endcap detachably connects to the body portion. The lancet is located within the body portion in a retracted position. The lancet is moveable between a retracted position and an extended position, and adapted to draw body fluid sample from the skin at a puncture site in an extended position. The vibration member extends through the endcap and is adapted to mechanically vibrate the skin adjacent to the puncture site. The lancet is adapted to draw the body fluid sample from the skin at a puncture site by extending through an opening formed in the endcap, the vibration member or the combination thereof. One example of a vibration member is a piezoelectric member.

  • Publication number: 20040243164
    Abstract: A lancet device for obtaining a blood sample from a finger or at an alternate site of a patient. The lancet device includes a body and a lancet, the lancet being movable between a retracted position in which the lancet tip is disposed within the body and an extended position in which the lancet tip extends beyond the body. The device is cocked by compressing a U-shaped spring steel accessible on opposite sides of the body, the U-shaped spring steel being coupled to the lancet. Once cocked, a pawl retains the U-shaped spring steel in a compressed state. The device is fired by contacting the patient where sampling is to occur with one end of an actuator, the opposite end of the actuator serving to release the pawl from the U-shaped spring steel.
