ABSTRACT:
An aseptic solution for IV administration is prepard by thrusting a drug vial over a needle of a connector having a valve provided with a sterilizing air filter. In a first position of the valve, the communication to the IV container is blocked, but the vial is connected to the atmosphere through the sterilizing air filter to allow equalization of the atmospheric pressure with the pressure in the vial. In the second position, the communication with the filter is cutoff and the vial is connected to the IV container to allow IV solution to enter the vial and solution to be transferred between the vial and the IV container. In a final position, the ports of the valve are all blocked to close off the vial in which the sterile air is now trapped so that loss of the IV solution into the vial will be prevented.
