摘要： A hypodermic syringe with a selectively retractable needle includes an elongate barrel having an open proximal end, an open distal end and a hollow bore. The syringe includes an elongate plunger including a hollow outer housing having an open proximal end and an open distal end. The plunger has a hollow inner sleeve defining a cavity therein. The plunger has releasable engagement elements preventing relative axial movement between the outer housing and the inner sleeve, the elements allowing the relative axial movement when released and a distal stopper. There is an open cutter mounted at a proximal end of the inner sleeve to cut through the stopper to expose the cavity in the inner sleeve when the engagement elements are released and sufficient distal axial force is applied to the plunger. The syringe has a hub housing with an open proximal end having an inwardly projecting shoulder, a hub with a proximal flange and an axial stem, sized to fit within the hub housing. There is a spring disposed about the stem between the flange and the shoulder. The syringe has a needle with a sharp point extending outwardly. The needle retracts into the cavity in the plunger when sufficient distal force is applied to the plunger to release the engagement elements. The release allows movement of the inner sleeve with respect to the outer housing so that the cutter cuts through the stopper and the flange and the spring urges movement of the needle into the cavity.

摘要： A retractable needle syringe includes a barrel defining a receiver. There is a plunger having an inner rod extending distally from the proximal end. The plunger includes a hollow sleeve that is disposed over and extend beyond an inner rod. The plunger includes a hollow cutter extending from the inner rod and a stopper disposed over the end of the sleeve. The plunger has a displaceable collar to prevent movement of the inner rod with respect to the sleeve, that is by distal force to the plunger by engagement with the proximal end of the barrel allowing the cutting surface to cut through the stopper. There is a hub with a stem, a proximal flange and an engagement. A clip having a proximal foot with an opening therethrough and a distal grip is disposed on the stem of the hub. The proximal foot of the clip is disposed at the distal surface of the flange and the grip at the engagement on the stem. There is a spring disposed about the stem compressed between the receiver and the clip to provide a bias, so that when sufficient force is applied to the plunger causing the cutting surface to cut through the stopper, the cutting surface then engages, cuts through the flange to engage the clip and cause the clip to release the engagement on the stem. This allows the spring to urge the hub to a position within the syringe.

摘要： 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.

摘要： 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.

摘要： A method of making a retracting needle assembly for use with a syringe barrel having a cylindrical collar and a plunger having a release element with a sharp distal end includes an outer hub having a passageway therethrough and an inner hub having a proximal end, a distal end and a conduit therethrough. The proximal end of the inner hub has an inner portion and a dissociable outer portion connected to the inner portion. The dissociable outer portion is further connected to the outer hub. The distal end of the inner hub is smaller than the passageway of the outer hub at the distal end of the outer hub and projects distally outwardly therefrom. A needle cannula having a distal end, a proximal end, and a lumen therethrough is connected to the inner hub so that the lumen is in fluid communication with the conduit. An energized spring is contained between the inner and outer hub. Structure is provided for connecting the outer hub to the collar of the syringe barrel.

摘要： A retracting needle syringe is described which allows safe and easy disposal of a syringe and prevents re-use of the syringe by destroying the plunger rod and needle hub and retracting the needle into the plunger rod. Once the safety feature is activated, positive or negative pressure in the barrel to draw out medication is defeated. The retracting needle safety feature requires only an increase of force along the same line of action as the injection stroke. This allows for safe, one-handed injection, which is critical in some situations. The retracting needle syringe of the present invention also minimizes the amount of wasted medication because the plunger rod incorporates a plunger tip that occupies the entire volume inside the barrel. Because the retracting needle syringe uses standard luer-lok fittings, it can be used with a variety of standard needles that do not have retracting cannula. This gives the healthcare professional or patient the ability to use a large gauge needle to fill the syringe from a vial or other container before attaching the safety needle for injection. Lastly, the plunger can be completely encapsulated by the barrel upon activation of the retracting needle syringe safety feature which will prevent re-use of the syringe and allow for safe and easy disposal.
摘要翻译：描述了一种缩回针注射器，其允许安全且容易地处置注射器，并且通过破坏柱塞杆和针座并将针收回到柱塞杆中来防止注射器的再次使用。一旦激活了安全功能，就可以消除桶内出现药物的正压或负压。回缩针安全功能仅需要沿着与注射冲程相同的作用线的力的增加。这允许安全的单手注射，这在某些情况下是至关重要的。本发明的回缩针头注射器还使浪费的药物的量最小化，因为柱塞杆包括占据桶内的整个体积的柱塞头。因为回缩针头注射器使用标准的路厄 - 洛克配件，它可以与不具有回缩插管的各种标准针一起使用。这给予医疗保健专业人员或患者在附加用于注射的安全针之前使用大型针头从小瓶或其他容器填充注射器的能力。最后，在启动回针针头安全特征时，柱塞可以被筒完全包封，这将防止再次使用注射器，并允许安全和容易的处置。

摘要： 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.

摘要： 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.
