  • Patent number: 8394035
    Abstract: The invention concerns a device for collecting body fluids which has at least one lancet comprising a lancet body with at least two tips of different lengths. The device is characterized in that it has a selection means with the aid of which only one tip is selected before the lancing. This selection means can have different functions and shapes. The selection means is used to select a tip from a plurality of lancet tips which have different lengths and make only this tip available for use in the lancing process. Since the various tips are attached to a lancet body, it is, for example, possible to use a bending element which bends one of the various tips out of the plane of the lancet body in order to provide only one lancet tip for use. This is especially preferable for lancet tips that are arranged linearly relative to one another.

The advancing mechanism includes a linear-pull slide that is moved in and out to operate an indexing ratchet mechanism, a cam-guided charger mechanism, and a cam-guided lancet cap displacement mechanism. The indexing ratchet mechanism sequentially advances the lancets in the cartridge to an active position. The cam-guided charger mechanism charges the drive mechanism and separates the cap from the active lancet. And the cam-guided cap displacement mechanism moves the separated cap from the lancing stroke path of the active lancet. The activation mechanism then releases the charged active lancet to traverse the unobstructed lancing stroke path to pierce the subject's skin at a desired lancing site.

  • Patent number: 7670300
    Abstract: An apparatus for lancing skin and collecting a liquid sample. The apparatus having a housing with an outer periphery and a rotatable arm having a lance to puncture the skin. A sample collection area is attached to the arm. The arm of the apparatus rotates from a first position to a second position. As the arm rotates, the lance extends beyond the housing allowing the lance to contact the user's skin and create a lance site. As the arm continues to move to the second position, the lance is brought out of contact with the user's skin and back within the housing while the collection area is brought into position. When the arm is located in the second position, the collection area is in substantially the same location as the lance site on the user's skin.

  • Patent number: 7655019
    Abstract: A sampling device (20) having a housing (24) with a lancet cartridge (22) mounted therein. The lancets (26) of the lancet cartridge (22) are interconnected by a flexible web (28). The lancet cartridge (22) is not positively engaged within the housing (24) and can be easily removed. The housing (24) has an opening (42) with an adjacent flexible or compressible fin (60) for dampening the motion of the lancet (26). The lancet cartridge (22) has at least one lancet (26) with an endcap, and the housing has a cap-removal mechanism (74) for separating the endcap from the housing (24). Anti-tampering features prevent opening of the device when the lancet cartridge (22) is oriented with a lancet (26) in a firing position.

  • Publication number: 20080221581
    Abstract: A drilling guide cannula, having a serrated distal end in the form of axially moveable teeth which enables all or most of the teeth to maintain biting contact with the bone surface, essentially independently of the curvature of the bone surface and the drilling angle. The cannula outer wall incorporates a number of pins arranged circumferentially around the drilling bore. These pins slide axially relative to the cannula, preferably in bored holes or in channels formed within the wall of the cannula. Each of the secondary pins has a sharpened distal end, each constituting a moveable tooth. The cannula is applied to the bone to be drilled at the desired drilling position and angle, and the pins are forced axially towards the bone surface. The pins take up the contour of the bone surface and each pin bites into the bone surface to rigidly position the drilling guide cannula.

  • Patent number: 7377904
    Abstract: A medical lancing device including a replaceable multi-lancet cartridge. The lancing device includes an advancing mechanism that advances lancets within the cartridge into an active position, separates a protective cap from the active lancet, and energize a drive mechanism of the lancing device. A cap displacement mechanism moves the separated cap out of the travel path of the active lancet. In a first example embodiment, the cap displacement mechanism includes a cantilevered spring arm that displaces the detached cap of the active lancet. In a second example embodiment, the cap displacement mechanism includes a spring-biased cam-driven plunger that displaces the detached cap of the active lancet. Then an activation mechanism releases the energized active lancet to traverse the unobstructed lancing stroke path to pierce the subject's skin at a desired lancing site.

  • Patent number: 7303573
    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.
