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.

Contrast media injector

An improved enema insufflation system includes a source of barium sulfate suspension connected, by tubing, to a multi-lumen enema tip and a source of carbon dioxide, connected to the enema tip. The carbon dioxide source contains compressed carbon dioxide. The source is connected to a carbon dioxide reservoir capable of holding a pre-determined volume of carbon dioxide at a relatively low pressure. A hand actuated insufflation bulb is connected to the carbon dioxide reservoir. The insufflation bulb can draw carbon dioxide from the reservoir for delivery, through the enema tip, to a patient. The compressed, high-pressure carbon dioxide is functionally isolated from the patient to ensure patient safety.

Barium enema insufflation system

An apparatus is provided to deliver carbon dioxide to an animal in a manner which allows the carbon dioxide to totally displace blood in an area of interest and to thus serve as a contrast media for angiographic procedures, or blood displacement media for angioscopic or laser procedures. The apparatus enables the carbon dioxide to flow at varied flow rates, the varied flow rates correlated to the varied flow rate of blood in the animal's vascular system. The flow rate of the carbon dioxide is variable during the course of a single injection.
