ABSTRACT:
A needle ejector structure to be used with a syringe and structurally adapted to be removably inserted therein and driven into driving, disengaging relation to a connected hub portion of a needle upon forced travel of the plunger associated with the syringe thereby enabling separation and ejection of the needle from the syringe after use without the necessity of the needle or hub portion thereof being touched by medical personnel. Danger of contamination by inadvertent puncture when removing the needle is thereby eliminated.
