Lancet Patents (Class 606/181)
  • Patent number: 11826145
    Abstract: A tail pressing type disposable safety lancet includes a shell, a lancet core, a spring and tail cover. The shell has an elastic arm for locking the lancet core, wherein: the tail cover has an active locking part for locking and the elastic arm has a passive locking part for locking correspondingly; the positions, the fitting time of the active locking part and the passive locking part correlate with the active and passive unlocking parts; when the tail cover is pressed during use, it forces the lancet core to unlock for ejection and puncturing, and the tail cover and elastic arm enter the locking state and cannot be used again. After use of the safety lancet, the tail cover permanently locks on the elastic arm of the shell, ensuring the safety of single use, and the user visually recognizes the tail cover is retracted at the tail of the shell.

    Abstract: Surgical instruments and methods including a stop guard are described herein. An exemplary instrument can include an inner shaft disposed within an outer shaft, the inner shaft including a tissue-piercing tip and being effective to secure an end effector to the device. A stop guard can be coupled to the inner shaft and extend through outer shaft sidewall openings when the tip is advanced distally or retract into the outer shaft when the tip is retracted proximally. In a percutaneous procedure, external force applied to the stop guard by the tissue can retract the tip to prevent damage to surrounding tissue as the instrument is advanced distally. Moreover, once passed through pierced tissue, the stop guard can be redeployed when the inner shaft is advanced distally to secure an end effector to the instrument and can prevent inadvertent withdrawal of the instrument.

    Abstract: In some embodiments, the present invention generally relates to the separation of blood within a device to form plasma or serum. In some embodiments, the present invention generally relates to the removal of fluids, such as blood, contained within a device. In one aspect, the present invention is generally directed to systems and methods for receiving blood from a subject and processing the blood to form plasma or serum. For example, a device may be applied to the skin of a subject to receive blood from the subject and pass the blood through a separation membrane, which separates the blood into plasma and a portion concentrated in blood cells. As another example, blood or plasma may be allowed to clot within the device and serum (the unclotted portion of the blood) may be withdrawn from the device. The device may contain, in some cases, a vacuum source such as a pre-packaged vacuum to facilitate receiving of blood and/or passage of the blood through the separation membrane to produce plasma or serum.

    Abstract: A lancet magazine for use in a lancing aid is described comprising a plurality of lancets each having a lancet body at the proximal end of the lancet and a lancet tip at the distal end of the lancet, where the proximal end of the lancet points in the direction of the proximal end of the housing of the lancet magazine and the distal end of the lancet is aligned in the direction of the distal end of the housing and the lancets in the unused state are completely surrounded by the housing. Furthermore, an extension unit is movably connected to the housing in such a manner that the housing can be extended by movement of the extension unit in the direction of the distal end of the housing such that the lancet is prevented from emerging from the lancet magazine.

  • Patent number: 9844330
    Abstract: A lancet device generally includes a housing having opposing lateral sides extending between a forward end and a rearward end, and a shield coaxially and movably associated with the housing. The housing includes a plurality of longitudinal ribs extending along a portion of at least one of the opposing lateral sides. The plurality of longitudinal ribs form a finger grip on at least one of, and typically both of the opposing lateral sides. The shield is generally movable from a first position in which the shield extends outwardly from the forward end of the housing to a second position in which the shield is at least partially moved within the housing, based on axial pressure applied by the user against the finger grip formed by the longitudinal ribs.

  • Patent number: 9730626
    Abstract: A one-time/single use safety lancet system includes a body; a spring coupled to the body; a keeper having a deformable member; and a core for supporting a lancet and having an end coupled to the spring. The core further has a first latch for engaging the deformable member when the lancet system is in an armed state. The deformable member of the keeper is fractured after one use of the lancet system which prevents any subsequent arming of the lancet system. The keeper may be made part of the lancet body. The core may include a second latch, wherein the second latch permanently deforms or fractures the deformable member of the keeper after the single, one-time arming of the safety lancet system.

  • Patent number: 9517027
    Abstract: An advancement mechanism of a lancing device operates to sequentially advance lancets in a cartridge. The advancement mechanism includes a rotary drive gear assembly with a first gear and a second gear that co-rotate in a first angular direction by operation of an inter-gear unidirectional drive mechanism such as a ratcheting mechanism. A second-gear unidirectional lock mechanism, such as a ratcheting mechanism, locks the second drive gear from co-rotating with the first drive gear in a second opposite angular direction without impeding rotation in the first direction. The second gear directly or indirectly rotationally drives a pinion gear, which rotationally drives a cartridge gear to advance the lancets in indexed increments for use. The first drive gear is rotated in the first and second directions by a rack gear of a translating operating handle. In addition, a rotary-gear cap-displacement mechanism and a rotary-gear charging/actuation mechanism are provided in other embodiments.
