Abstract
Abstract A syringe holder for a conventional disposable syringe. The holder includes a needle assembly having a retractable needle for preventing accidental needle pricks. The needle assembly mounts to the forward end of a carrier having a chamber for receiving a hypodermic syringe. A plunger is slidably mounted in the carrier for moving the syringe between a loading/unloading position and a "use" position. As the hypodermic syringe is moved from its loading/unloading position to its "use" position, the hypodermic needle is extended through an aperture in the needle cap to expose the hypodermic needle. A locking means locks the hypodermic syringe in the "use" position during administration of medication to or drawing fluid from a patient. After use, the locking means is released and the needle is urged to a retracted position by a biasing means. The needle assembly and hypodermic syringe then are discarded.

A syringe holder comprising: (a) a carrier having a chamber sized for receiving and housing a hypodermic syringe including barrel and an extended syringe plunger, said syringe being moveable within said carrier between a loading/unloading position and a use position; (b) a needle assembly detachably secured at a forward end of the carrier including a retractable needle normally disposed in a retracted position, said needle being moveable to an extended position when the syringe is moved from its loading/unloading position to its use position; and (c) a lock for locking the hypodermic syringe in its use position during administration of medication to a patient.
Claim 3
Dependent Claim
29 words
The syringe holder according to claim 1 wherein the carrier comprises a generally cylindrical sleeve with the interior of the sleeve defining a chamber for receiving the hypodermic syringe.
Claim 4
Dependent Claim
39 words
The syringe holder according to claim 2 further including a side opening formed in the sleeve to permit insertion and removal of the syringe into and from the chamber in a direction perpendicular to the axis of the sleeve.
Claim 5
Dependent Claim
28 words
The syringe holder according to claim 3 further including a plunger slidably mounted in said sleeve for moving the syringe between its loading/unloading position and its use position.
Claim 6
Dependent Claim
