Abstract: A medical device for delivering a medicament to a patient. The device includes a syringe barrel with a plunger having a hollow front end and a stopper positioned over the plunger front end to seal the plunger front end. The stopper is movably inserted in the barrel to expel medicament in the barrel. A needle cannula is fixed to a needle cannula hub and is movable between an initial position in which the forward tip of the needle cannula is exposed and a retracted position in which the forward tip is contained within the medical device. A plug seal releasably secures the needle cannula hub to an end of the barrel, and a hub adapter secures the plug seal to the barrel end. A cutter positioned on the plunger pierces the stopper when the stopper is pressed against the plug seal to open the hollow front end of the plunger. The plunger also engages the plug seal to allow the needle cannula hub to move, via an urging member, to the retracted position through the front end of the plunger.

Abstract: A medical device includes a syringe assembly and a shield system for delivering medicament to a patient. The syringe assembly includes a barrel defining a medicament reservoir, a needle cannula coupled to the barrel and in fluid communication with the reservoir, a plunger having a stopper positioned in the reservoir and a thumb pad for moving the plunger in the reservoir. The shield system has a shield coupled to a forward end of the barrel, the shield being movable from a first position disposed from the needle cannula tip to a second position during insertion of the needle into a patient and movable from the second position to a third position covering the needle cannula tip after the needle cannula is removed from the patient. An urging member urges the shield to the third position upon removal of the needle cannula from the patient.

Abstract: A medical device for delivering medicament to a patient including a syringe assembly, a shield body, a retainer and an urging member. The syringe assembly includes a barrel defining a reservoir for medicament, a needle cannula coupled to the barrel and in fluid communication with the reservoir, a plunger having a stopper positioned in the reservoir and a thumb pad for moving the plunger in the reservoir. The syringe barrel is movable within the shield body between a first position exposing the forward tip of the needle cannula, and a second position where the tip of the needle cannula is in the shield body. A retainer secures the syringe barrel in the first position. An urging member urges the syringe barrel from the first position toward the second position upon interaction with the thumb pad and upon the release of pressure applied to the thumb pad.

Abstract: A medical device for delivering a medicament to a patient includes a syringe assembly having a syringe barrel, a needle cannula coupled to the syringe barrel, and a plunger having an end connected to a stopper for insertion into an end of the barrel. A shield system is provided for preventing inadvertent needle sticks after use of the syringe. The shield system includes an actuator mounted on the syringe barrel and movable from an initial position to a retracted position in response to the application of the medicament delivery force. A shield arranged on the front portion of the barrel is responsive to the position of the actuator to deploy the shield from a first position wherein the tip of the needle cannula is exposed, to a second position wherein the shield covers the needle cannula tip.

Abstract: The present invention is a needle holder assembly for using during a blood collection procedure and more particularly to a blood collection tube holder with means for easily engaging and disengaging a blood collection needle from the holder and for not prematurely disengaging a blood collection needle. The needle holder includes an engaging trigger to engage the holder with a needle and a disengaging trigger to disengage the holder with a needle and a preventative needle release indicator that prevents premature movement of the disengaging trigger and disengagement of the needle from the holder.

Abstract: A document reproduction apparatus with an mounting mechanism for the document handler, which can be, for example, hinge/counter-balance mechanisms for supporting a document handler on the frame of the copier or other reproduction apparatus, in which the spacing of the document handler from the underlying imaging platen can be much more easily and accurately adjusted by the integral variable position adjustment mechanism including eccentrically faceted rotatable spacing cams. In the exemplary mechanism a first member for attachment to the document handler, is pivotally mounted about a pivot axis with a hinge pin to a second member for mounting to the frame of the copier, and has an adjustment system for adjusting the position of the first member relative to the pivot axis.
