Abstract
An apparatus is provided for use with a contrast media injector. The injector is of the type including a gas source and a liquid source. The apparatus includes a gas delivery channel connected to the gas source and a liquid delivery channel connected to the liquid source. Two normally closed valves are provided to control flow from the gas and liquid channel. The valves insure that gas and liquid do not simultaneously exit from the channel. The valves minimize inadvertent mixing of the gas and saline downstream of the valves. The gas channel is connected to a gas source using a fitting which also connects electro-conductive wires in the apparatus to a power source. The liquid channel connects to a source of liquid.
