ABSTRACT:
A fluid aspiration needle assembly comprising a linearly elongated, tubular needle having a first end to be positioned at or proximate a patient's body, and an opposite end portion; a hub integral with the opposite end portion of the needle and providing a reservoir, the hub having a first duct in linear communication with the needle via the reservoir, and there being a second duct in communication with the reservoir and branching relatively away from the first duct, the second duct connected to the hub; the first duct, reservoir and needle being in linear alignment to receive an elongated stylet having a sharp end, and manipulable to cause the sharp end to penetrate the patient's body, and to be withdrawn so that body fluid can pass through the needle and enter the reservoir; and flexible, coupler tubing operatively connected to the second duct for passing fluid between the reservoir and a syringe operatively connected to the reservoir via the flexible tubing, whereby the syringe may be bodily manipulated in force-transmitting relation isolation relative to the needle.
