Abstract

An adapter for interfacing a needle-less syringe with a medication vial is disclosed. The adapter has a body and a detachable means for sealably receiving the inlet of the syringe at one end. The detachable means is substantially centered about the body and has a central bore fluidically connecting the adapter with the syringe. Extending substantially perpendicular to the body and opposite to the detachable means is a piercing means which is substantially elongated in shape. The piercing means has a longitudinal axis with a spike bore extending along the longitudinal axis fluidically connecting the central bore with the spike bore. An adapter inlet is positioned along the longitudinal axis fluidically connecting to the spike bore, at a distance such that the distance between the inlet and the body is greater than the thickness of the cap of the medicine vial. At least two resilient permanent attachment means extend from the body substantially in the same direction as the piercing means with each limb having a length less than that of the piercing means. Angled foot members are attached to the distal ends of each of the limbs with each of the foot members having guide means extending inward and upward from the limb towards the piercing means, and permanent attachment hook means on the end opposite the guide means.

Claims

1. An adapter device for withdrawing medication from a medicine vial into a syringe without the use of a needle, the medicine vial having a permanently affixed elastomer cap having a diameter and a thickness, the syringe having an inlet, the adapter device comprising:

a body;

detachable means for sealably receiving the inlet of the syringe, said means being substantially centered on said body and having a central bore fluidically connecting said adapter device with the syringe;

means for sealably piercing the cap of the medicine vial, said piercing means extending substantially perpendicular to said body and opposite said detachable means, being substantially elongated in shape, having a longitudinal axis with a spike bore extending along the longitudinal axis fluidically connected to the central bore and having an adapter inlet, fluidically connected to the spike bore, positioned along the longitudinal axis at a distance between the inlet and said body greater than the thickness of the cap;

at least two resilient attachment limbs extending from said body substantially in the same direction as said piercing means, separated from one another by a distance equal substantially to the diameter of the cap, each of said limbs having a length less than that of said piercing means and equal substantially to the thickness of the cap; and

angled guiding foot members attached to the distal ends of each of said limbs, each of said foot members having guiding means and locking means with the locking means extending inward from said limbs towards the piercing means and towards the detachable receiving means with said locking means separated from one another by a distance less than the diameter of the cap and with the guiding means extending outward from said limbs away from the piercing means and away from the detachable receiving means, with said guiding means separated from one another by a distance greater than the diameter of the cap.

2. The adapter device recited in claim 1, further comprising a cap for removably covering said receiving means.

3. The adapter device recited in claim 1, wherein said detachable receiving means further includes luer fitting means for releasably securing the inlet of the syringe to said receiving means.

4. The adapter device recited in claim 1, wherein said piercing means is a spike.
