Medication vial adapter

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.
