  • Barium enema insufflation system
    Patent number: 5322070
    Abstract: 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.
