  • Publication number: 20220395647
    Abstract: A safety pen needle assembly includes a hub with a needle fixed to the hub, the needle having a distal end, formed for insertion into a patient, and a proximal end, a shield and a biasing member disposed between the hub and the shield configured to urge the shield distally. The shield is movable from a first position, when the needle is exposed, to a second position, when the needle is covered. The distal end of the needle may be initially exposed to permit visual confirmation of priming, while allowing the shield to cover a majority of the needle to minimize any needle-related anxiety.

  • Patent number: 11446449
    Abstract: In one aspect, a safety pen needle assembly is provided herein which includes a hub with a needle fixed to the hub, the needle having a distal end, formed for insertion into a patient, and a proximal end. The assembly further includes a shield and a biasing member disposed between the hub and the shield configured to urge the shield distally. A protrusion extends from at least one of the hub and the shield with a channel being formed in at least the other of the hub and the shield. The channel is formed to accommodate the protrusion. The shield is movable from a first position to a second position. In the first position, the shield is spaced from the distal end of the needle such that the distal end of the needle is exposed. In the second position, the shield covers the distal end of the needle. The channel guides the protrusion as the shield moves from the first position to the second position. With this arrangement, a shield may be directed to move in a desired path with stability.

  • Patent number: 10555793
    Abstract: The present invention employs a self-ligating orthodontic bracket comprising a body having a pair of laterally spaced gingival tie wings and a pair of laterally spaced occlusal tie wings, the gingival and occlusal tie wings projecting from a labial surface of the body; an arch wire slot extending mesially-distally across the body and between the gingival and occlusal tie wings to accommodate an arch wire; a free-sliding, controlled-locking, or pivoting clip wherein the clip allows placement and removal of the arch wire when in the open position and prevents the displacement of the arch wire from the bracket member when in the closed position.

  • Patent number: 10398858
    Abstract: A safety needle assembly, including a hub; a needle fixed to the hub, the needle having a distal end and a proximal end; first and second shields, each having a tubular body at least partially encircling a portion of the needle, wherein in an initial state, the first shield extends from the hub; a biasing element disposed to urge the second shield distally toward the distal end of the needle; and a releasable retaining arrangement for releasably retaining the second shield in a first state. Upon a predetermined extent of proximal movement of the first shield relative to the hub, the second shield is released, thereby allowing the biasing element to urge the second shield to a second state in which the distal end of the needle is covered.

  • Patent number: 9622688
    Abstract: A lancet-release mechanism is adapted to be incorporated into a lancing device. The lancing device is adapted to receive a lancet assembly therein. The lancing device is adapted to move the lancet assembly between a resting position, a cocking position, and a puncture position. The lancet-release mechanism comprises a lancet holder and a cantilever beam. The lancet holder forms a central aperture. The central aperture is adapted to receive the lancet assembly therein. The lancet holder further forms a plurality of protuberances thereon. The cantilever beam has a projection extending therefrom. The projection is adapted to engage the plurality of protuberances located on the lancet holder. The projection is adapted to separate the plurality of protuberances from each other so as to enlarge the central aperture.
