A trigger element releasably secures the urging member in a charged state and releasably secures the cap in the first position. The trigger element is actuatable to release the cap by either manual actuation or by interaction with the thumb pad.

Abstract: A medical device for delivering a medicament to a patient includes a syringe assembly having a barrel defining a reservoir for the medicament, a needle coupled to the forward end of the barrel, and a plunger having a stopper positioned in the reservoir. The plunger is movable within the reservoir to urge the medicament to be expelled from the reservoir. An outer shield having a forward end and a rear end is movable on the barrel from a first position to a second position in which the forward tip of the needle is positioned between the forward and rear ends of the outer shield. An urging member is connected to the outer shield. The plunger interacts with the outer shield to charge the urging member when the needle cannula is inserted into the patient for moving the front of the outer shield toward the second position when the needle is removed from the patient.

Abstract: A shieldable needle device including a needle cannula, a hub, a pair of wings extending laterally from opposing sides of the hub, a tip guard axially movable along the needle cannula from a proximal position substantially adjacent the hub to a distal position, and a drive member is disclosed. The drive member includes a first end connected to the hub and a second end connected to the tip guard and is extendable between a folded biased position and an extended position for moving the tip guard from the proximal position to the distal position. The pair of wings, when in a dorsal position, retain the drive member in the folded biased position maintaining the tip guard in a proximal position. Upon release of the wings, the drive member unfolds, extending the tip guard from the proximal position toward the distal position.

Abstract: A delivery device for delivering a substance intradermally into the skin of a patient including a housing for contacting the surface of the skin and a disposable cartridge to be received in the housing. The cartridge includes an internal reservoir containing a substance to be delivered to the patient, a plurality of micro skin penetrating members and a fluid channel extending between the micro skin penetrating members and the reservoir. The housing includes a bottom wall with a central opening and a cover member. The cartridge is positioned in the housing with the micro skin penetrating members extending through the central opening of the bottom wall and positioned on the surface of the skin of a patient. The cover is closed onto the cartridge to dispense the substance from the cartridge through the micro skin penetrating members and into or through the skin of the patient.

Abstract: A blood collection device includes a needle hub with a flashback chamber and a vent plug covering the flashback chamber. The vent plug permits a flow of air across the vent plug but prevents a flow of liquid across the vent plug. An intravenous cannula is mounted to the hub and extends into the flashback chamber. A non-patient cannula is mounted to the hub and also extends into communication with the flashback chamber. A passive shielding device is mounted to the hub and can be moved from a proximal position where the intravenous cannula is exposed to a distal position where the intravenous cannula is partly shielded. The flashback chamber can be observed to provide an early indication of venous access. A fluid collection tube then can be placed in communication with the non-patient needle and can simultaneously trigger movement of the safety shield.

Abstract: A needle shield assembly including a hinged needle shield is provided. A ramp is provided in proximity to a hinge that connects the needle shield to base assembly. The ramp is preferably flexible, and, if compressed, resliently urges the needle shield to a preferred angular position where it is canted at an angle with respect to the syringe and a closed position in which it envelops the needle. One or more locking elements are preferably provided on the needle shield for maintaining it in a locked, needle protection position.

Abstract: A shielding medical device includes a needle cannula, a hub, a release element, a needle shield, and a biasing member. The hub has a proximal end, a distal end, and a passageway in fluid communication with the needle cannula. The distal end of the hub supports the needle cannula. The release element is fixed to the hub. The needle shield is hollow and has a proximal end, a distal end, and a pair of wings extending laterally from opposing sides. The proximal end of the needle shield is removably secured to the release element. The needle shield is axially movable with respect to the needle cannula from a first position in which the needle cannula is exposed to a second position in which the needle cannula is shielded within the needle shield. The biasing member is used to move the needle shield from the first to second positions.

Abstract: A needle holder for use with a needle assembly for blood collection is provided. The needle holder includes a generally tubular housing having a needle shield at a first end thereof, and a cutaway notched portion at the other end thereof. A plurality of such needle holders can be stacked in a nested fashion within each other with the cutaway notch of one needle holder accommodating the needle shield of another needle holder.

Abstract: A shieldable needle device is provided. The shieldable needle device includes a housing, a needle cannula, a tip guard and a flexibly resilient drive mechanism. The housing includes a first lateral extension and a second lateral extension which are interconnected at a rearward end to form a hub portion from which the needle cannula extends. The tip guard telescopes over the needle cannula from a retracted position to an extended position. The drive mechanism is attached to the tip guard and is bent or coiled within the housing between the first and second lateral extension and retained in the bent or coiled position. Upon release of the drive mechanism, the tip guard is moved from a retracted position to an extended position, thereby protectively surrounding a tip of the needle cannula.

Abstract: A shieldable needle assembly provided as part of a blood collection set includes a needle cannula having a proximal end and a distal end with a puncture tip. The needle assembly has a hub member supporting the proximal end of the needle cannula and a shield member having a housing defining a central bore, which is in axial alignment with the hub member. The shield member extends co-axially about the needle cannula and is movable between a retracted position in which the puncture tip of the needle cannula is exposed, and an extended position covering the puncture tip of the needle cannula. An extendable member connects the hub and shield members. A compression spring is further connected between the hub and shield members for moving the shield member to the extended position. A latch assembly provides releasable engagement between the hub and shield members.

Abstract: A retractable safety needle assembly is provided. The needle assembly includes a tubular outer body, a retraction assembly contained with the outer body and a biasing element for applying a retraction force therebetween. The retraction assembly includes a cannula having an intravenous puncture tip and a non-patient puncture tip at opposing ends. In a first position, the intravenous puncture tip extends from a first end of the tubular outer body. The retraction assembly is adapted for movement within the tubular outer body from the first position to a second position in which the intravenous puncture tip and the non-patient puncture tip are contained entirely within the tubular outer body and are offset from a general axis defining the outer body.

Abstract: A laser lancet tip and method for controlling laser incisions for the purpose of taking blood samples from patients in a variety of body locations and age groups. A removable tip on a laser is used to mask a laser pulse and modify the length and width of an incision made by the laser by only allowing a portion of the laser beam to contact the target surface. The depth of the incision may be controlled by either a lens or filter which is optically aligned with the laser beam.
