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.

Syringe having a retractable needle

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.

Safety shield system for a syringe

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.

An urging member controlled by a retaining device urges the second shield to the second position upon movement of the stopper to a position which releases the retaining device.

Safety device for a syringe

The present invention is a safety shield assembly having a shield and a collar for connecting the shield to a fluid handling device whereby the shield may be pivoted with respect to the collar. Preferably, the safety shield assembly may be used with a needle assembly, an intravenous infusion set a syringe, a catheter or other fluid handling devices or assemblies that contain piercing elements.

Safety shield assembly

The present invention is a method of using a safety shield assembly having a shield and a collar and more particularly a method of using a safety shield assembly with a fluid handling device whereby the shield may be pivoted with respect to the collar. Preferably, a method of using a safety shield assembly with a needle assembly, an intravenous infusion set a syringe, a catheter or other fluid handling devices or assemblies that contain piercing elements.

Method of using a safety shield assembly and related combinations thereof

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.
