Abstract:
A vial access adapter-vial assembly comprising:(a) a vial having a medical fluid therein; and (b) a vial access adapter body; wherein said vial comprises:a cylindrical side wall having a distal end and a proximal end, said distal end extending into a constricted neck portion terminating in a rim and defining an open fluid port, and said proximal end being closed by a flat bottom portion; said fluid port being closed by an elastomeric stopper having a top surface and bottom surface; wherein said vial access adapter body comprises:a cylindrical side wall having a distal end and a proximal end terminating in a rim; a flat, horizontal top wall, closing the distal end of the cylindrical side wall, and having vent holes therein; a horizontal second wall parallel to said horizontal top wall and spaced therefrom, said horizontal top wall, second wall and cylindrical side wall enclosing a chamber designed to hold a filter therein; an externally threaded luer connector means projecting vertically above the horizontal top wall for receiving an internally threaded luer connector of a syringe or cartridge; an elongated first spike terminating in a sharp point, having a fluid flow channel therein, and being integral with said luer connector, extending into said vial and reaching the bottom portion thereof to allow withdrawal of essentially all the medical fluid form the vial when said vial is in the rightside-up position; a second spike positioned parallel to said first spike extending downward from said horizontal second wall and terminating in a sharp point; an air flow channel in said second spike designed for air flow passage from said chamber into said vial during withdrawal of said medical fluid from said vial; an anti-bacterial filter positioned in said chamber to prevent entry of bacteria into the vial from the atmosphere; an elastomeric membrane within said externally threaded luer connector for sealing said fluid flow channel; wherein said first spike is pierced through said elastomeric stopper to establish fluid communication with said medical fluid contained in the vial, and said second spike is pierced through the elastomeric stopper and extending just below the bottom surface of said elastomeric stopper to establish air flow communication from said chamber into said vial.
