Abstract: A link for use between a needleless syringe and a liquid medicine vial may be used equally well with both Luer lock and slip tip syringes. An adapter flange forms both an anchor for a conventional Luer lock and a receiving receptacle for a conventional slip tip syringe. The bottom end of the receiving receptacle is capped with a cylindrical sieve providing multiple fluid flow paths. The vial end of the link is formed with a pocket for collecting fluid when the vial is inverted. Two separate versions are provided, with one having a flip-top cap flush with the top of the medicine vial and the other having a twist-off top extending above the top of the vial. An outer jacket, surrounding the vial top is an optional variation on either version and provides for resealing of multiple dose vials. A valve automatically seals the vial to protect against loss of fluid and contamination of remaining fluid within the vial, in the event that the vial is overturned.
