  • Publication number: 20180214136
    Abstract: Single and multiple allergy skin testing devices with rigid annular pain-reduction structures supported by respective compressible sleeves. Each rigid annular pain-reduction structure presses against skin before and while at least one corresponding sharp probe presses against the skin surrounded by the rigid annular pain-reduction structure, thereby causing a surrounding pain gate effect to reduce perceived pain due to the at least one sharp probe. Each allergy skin testing device includes: a central post having a sharp portion, a longitudinal portion, and a guide portion; a compressible structure having a leading portion, a resilient compressible portion, and a base portion; and a rigid annular probe portion having an annular skin-contacting surface.

  • Publication number: 20180214065
    Abstract: An allergy skin testing device includes a central post having a sharp portion, a longitudinal portion, and a guide portion. The sharp portion has one or more sharp probes extending longitudinally. The guide portion facilitates guiding the sharp portion towards the skin. The device also includes a compressible annular pain-reduction structure having an annular dull probe portion, a resilient compressible portion, and an optional base portion. The annular dull probe portion initially extends beyond the sharp portion, and has a passageway allowing passage of the sharp portion therethrough, the annular dull probe portion being configured to activate a surrounding pain gate effect (a “pain gate fence”) when pressed against the skin. The resilient compressible portion is configured to compress along the longitudinal portion of the central post. The base portion is configured to be pushed by the guide portion when the annular dull probe portion is pressed against the skin.

  • Patent number: 8574193
    Abstract: A retractable needle syringe having a plunger rod configured to lock in place after retraction of the needle. The plunger rod distal end has a seal configured to advance past a retaining ledge after retraction of the needle, whereby the retaining ledge restricts or inhibits the plunger from proximal movement.

  • Patent number: 8535267
    Abstract: A retractable needle syringe having a segmented retaining ledge at the distal end of the syringe barrel. The retaining ledge has uniformly spaced members configured to enable the retaining ring to break from the needle stem with a reduced plunger engagement force, which provides an improved tactile feeling of the syringe plunger and comfort of use. The segmented retaining ledge also makes it easier to install the needle stem and retaining ring in the barrel distal end, such that it snaps into place therepast with less axial force.

  • Publication number: 20130018325
    Abstract: A flange extender for use with an injection device is described. The flange extender includes first and second flange extender pieces and a locking mechanism to lock the first and second flange extender pieces to one another. In one embodiment, the locking mechanism includes each piece having a locking finger extending from the piece and an aperture adapted to receive the locking finger. The first and second flange extender pieces extend in a direction transverse to a main axis of the injection device to thereby provide a surface area for manual manipulation of the injection device during an injection. The first and second flange extender pieces also attach to each other on opposite sides of the injection device.

  • Publication number: 20120232480
    Abstract: A retractable needle syringe having a conical frustum tip configured to selectively attach to a Luer device including an inexpensive commonly found Luer filling needle, and also including an interchangeable needle assembly configured to secure to a needle stem positioned within the conical frustum tip. The conical frustum tip advantageously facilitates aspirating a medicant, using a common Luer needle for filling and also prevents the possible unintentional retraction of the needle assembly due to hydraulic pressures encountered when drawing the medicant from a vial and during the handling of the syringe. Moreover, the conical frustum tip advantageously allows the syringe to be conveniently prefilled with a medicant at a pharmacy and capped, then transported to a patient with or without needle assembly as desired. This design is a significant advantage for many healthcare workers involved in the processing and handling of syringes until ultimate delivery of the medicant to a patient.

  • Publication number: 20120232481
    Abstract: A retractable needle syringe, including a needle stem and breakable ring having a plurality of fingers and grooves. These fingers and grooves are configured to mate with a plurality of ribs and grooves in a syringe barrel distal end to provide anti-rotation of the needle stem with respect to a syringe barrel. This anti-rotation feature restricts rotation of the needle stem when attaching or exchanging needles to prevent unintended retraction.

  • Patent number: 7972303
    Abstract: Syringe assemblies having a passive disabling system to prevent reuse are provided. In one embodiment, the passive disabling system activates after completion of an injection cycle. An exemplary syringe assembly incorporates a stopper and plunger rod attached in a manner to prevent users from disassembling the syringe prior to completion of the injection cycle. The barrel may also include an annular extension or collar that extends from the proximal end of the barrel. In a specific configuration, the annular extension at least partially envelopes a portion of the thumb press to prevent the user from accessing the thumb press and moving the plunger rod in a proximal direction Syringe assemblies of one or more embodiments also include visual indicators or markers indicating whether a syringe assembly is used or the plunger rod is locked within the barrel.

  • Patent number: 7717881
    Abstract: A medical device for use with a fluid transfer device includes a hub having an open proximal end with a frusto-conically-shaped cavity therein, a distal end and a passageway therethrough. The cavity is part of the passageway. A release element in the passageway of the hub is positioned to block fluid-tight engagement of the frusto-conically-shaped tip with the cavity of the hub. Structure is provided to release at least part of the release element, upon application of a proximally directed force on the hub, to allow the abrupt fluid-tight engagement of the tip and the cavity in the hub.
