Spring Driven Or Biased Into Cutting Position Patents (Class 606/182)
  • Patent number: 8382680
    Abstract: The present invention provides a hand-held analysis instrument for analyzing a body fluid. The instrument comprises a housing with a housing opening to which a body part, in particular, a finger, can be applied to generate a puncture wound, an analysis unit for analyzing a sample of a body fluid obtained at the puncture wound, and a piercing unit including a lancet and lancet drive for generating a puncture movement of the lancet. The piercing unit, including the lancet drive, is movable between an operating position and a rest position, the piercing unit being located at the housing opening in the operating position in such a manner that by means of the lancet a puncture wound can be generated in a body part pressed against the housing opening, and the piercing unit being remote from the housing opening in the rest position in such a manner that the space in front of the housing opening is free for the analysis unit, so that it can be moved into a position for receiving blood.

  • Publication number: 20130041393
    Abstract: A lancet device includes a hollow housing defining a cavity and having a proximal end and a distal end and a slider slidable at least partially within the cavity along a longitudinal axis from an outward position to a pushed position. The slider extends outside of the cavity beyond the proximal end when it is in the outward position. A needle holder holding a needle is rotatable about and translatable along the longitudinal axis when moved from an initial position to an extended position. When the needle holder is in the initial position, the slider is in the outward position. When the needle holder is in the extended position, the lance extends beyond the proximal end. Sliding of the slider to the pushed position enables a first biasing member to urge the needle holder toward the extended position. A second biasing member can be present in the lancet device.

    Abstract: A disposable safety lancet device employed in an automated and painless procedure includes an outer casing, an inner sleeve, a lancet assembly and a spring. A lancet tube is provided in the lancet assembly. One end of the lancet assembly is snapped in the inner sleeve, and the other end is extended into the outer casing. Interlock fixing faces and protrusions are provided on the inner sleeve. Interlock guiding slopes and protrusion stoppers are provided on the inner wall of the outer casing. One end of the interlock engages the interlock fixing face, and the other end engages the interlock guiding slope. A lancing operation for taking blood can be simply performed only by turning wing plates having rib portions, aligning a blood taking aperture, and pushing the outer casing. After the lancing operation, the lancet tip is retracted into the inner sleeve, which prevents a second use by the fixation between the inner sleeve and the outer casing.

  • Publication number: 20130035709
    Abstract: A surgical device mitigates over-puncture with a bias spring that biases a leading, cutting edge in the opposite direction of the anticipated over-puncture. An associated locking mechanism is configured to release the force of the bias spring in a direction counter to the direction of insertion when the tension force of tissue against the cutting edge is released. Thus, when an opening in the tissue forms, the tension is released and the cutting edge can move opposite to the direction of insertion of the surgical device at the same time that an applied force drives the instrument in the direction of insertion. In this manner, the spring and locking mechanism cooperate to move the cutting edge opposite to the direction of insertion as soon as an incision is made.

  • Patent number: 8231549
    Abstract: A sampling device for sampling body fluid includes a lancet for making an incision, a capillary tube for drawing-up body fluid from the incision, and a test strip affixed to an upper end of the capillary tube for receiving the fluid. An absorbent pad can be disposed between the test strip and capillary tube for spreading-out the fluid being transferred to the test strip. An on-site analyzer such as an optical analyzer and/or an electrochemical analyzer can be mounted in the device for analyzing the fluid. Alternatively, a test strip can be slid through a slot formed in the bottom end of the device so that by passing the device against the skin after an incision has been formed, the test strip will directly contact body fluid emanating from the incision.

  • Publication number: 20120191122
    Abstract: Disclosed is a disposable blood collecting instrument that stably secures a sufficient volume of blood with a single puncture. A tip portion of a piercing body of a lancet contained within a housing projects by means of a biasing force of a spring assembly, and a surrounding area of an opening of the housing is made a transparent visible portion with a visible interior. Additionally, the disposable blood collecting instrument has been formed such that the spring assembly is contained within housing farther behind the piercing body than a position of the tip portion of the piercing body that has entered within the housing after piercing.

  • Patent number: 8216263
    Abstract: A lancet removal tool 26 comprises an elongate hollow body 28 having an opening 32 at one end. The opening 32 is bounded by resilient fingers 36 which can flex to expand the opening 32 to engage the body 16 of the lancet 14. Withdrawal of the tool 26 after engagement with the lancet body 16 causes the lancet 14 to be removed from the lancet device. Subsequently, the lancet 14 can be moved from the opening 32 into the interior of the tool 26. The tool 26 and the removal procedure enables lancets 14 to be removed without risk of injury or infection from contact with the contaminated needle 18 of the lancet 14.
