  • Patent number: 11576659
    Abstract: A bone marrow aspiration device and related method includes an introducer assembly and an aspiration assembly to couple to the introducer assembly. The introducer assembly includes an introducer cannula having a proximal end and a distal end. The introducer cannula defines a lumen between the distal and proximal ends, the distal end being configured to penetrate bone of a patient. The aspiration assembly includes an aspiration cannula that is receivable in the lumen of the introducer cannula and that extends beyond the distal end of the introducer cannula. The aspiration cannula includes a port to aspirate bone marrow, the port being distal to the distal end of the introducer cannula. The aspiration device further includes a mechanism at the introducer assembly to move the introducer cannula and the aspiration cannula in tandem relative to a distal end of the mechanism when the aspiration cannula is positioned within bone.

  • Patent number: 11571523
    Abstract: A syringe and needle hub for a syringe has distal patient-facing side having a surface for contact with the subject's skin during injection. The contact surface is formed by a distal face of a post supporting a cannula and an outer collar surrounding the post. The axial distance between the distal face of the post and the distal face of the collar provided a contact surface with a radius of curvature to control the desired injection. The syringe barrel can have finger flanges extending outwardly where the flanges have a tactile member such as a dimple projecting from a proximal face of the flange and recess in a distal face of the flange.

  • Patent number: 11541190
    Abstract: A device configured to administer a medication can comprise a lower housing that includes a housing latch. The device can further comprise a needle guard that is movable relative to the lower housing along a first direction from a first position to a second position so as to expose a needle, and an upper housing supported relative to the lower housing. The upper housing can be configured to move with respect to the lower housing along a second direction from a pre-use position to a dispensed position. The housing latch can releasably interfere with the upper housing when the upper housing is in the pre-use position so as to prevent the upper housing from moving toward the dispensed position, and the movement of the needle guard toward the second position, causes the interference to be removed, thereby allowing the upper housing to move toward the second position.

  • Patent number: 10835690
    Abstract: Disclosed is a puncture depth controlling and needle hiding device and a usage method thereof. The puncture depth controlling and needle hiding device comprises a housing and an inner sleeve. The inner sleeve is positioned in the housing and is rotatable. Correspondingly matched limiting structures are provided on an inner wall of the housing and an outer wall of the inner sleeve. A spring is provided between the housing and the inner sleeve to push the proximal ends of the housing and the inner sleeve to be separated and keep the inner sleeve at an initial axial position with respect to the housing. By means of the invention, the medicinal liquid injection operation is simplified, and the need insertion depth is accurate. A needle hiding structure reduces the risk of accidental stab.

  • Patent number: 10828480
    Abstract: An applicator according to one embodiment includes a housing having a tubular shape with one closed end, and configured to house an elastic member and a piston plate for transmitting biasing force of the elastic member to the microneedles, and release means configured to release the piston plate engaged in a manner resisting against the biasing force of the elastic member in the housing, to cause the piston plate to move toward an opening of the housing along an axial direction of the housing. The release means is configured, when the release means releases the engagement of the piston plate by moving toward the housing in the axial direction, to transmit force in a direction toward the opening to the housing.

  • Patent number: 10653851
    Abstract: Described is an autoinjector comprising a case, a chassis slidably arranged in the case, a syringe carrier operably coupled to the chassis, an outer plunger selectively engaged to the chassis, an inner plunger selectively engaged to the outer plunger, and a drive spring applying a biasing force to the outer plunger. The biasing force is applied to the inner plunger when the inner plunger is engaged to the outer plunger. Rotation of the chassis causes the inner plunger to rotate relative to the outer plunger and disengage the outer plunger to remove the biasing force from the drive spring on the inner plunger. When the inner plunger disengages the outer plunger, the biasing force of the drive spring pushes the chassis to retract the syringe carrier relative to the case.
