3. Rectal Double Balloon Catheter for Barium Enema

There are several problems which need longer examination period or much experince and technique to obtan meaningful films of the colon. The other important factor for the colon examination would be the material such as a rectal balloon catheter.It has been improved by many people however, there has not been a satisfactory product.Since 1972, we have been trying to develop the remote controlled apparatus for the colon examination using the X-ray television set with S. Takane et al. While applying this apparatus, there had been also several problems as follows : sended contrast media or air for the double contrast used to come out of the anal side or the catheter easy to detach from the rectum while changing the patient's position and a severe movement in infants or due to the insufficiency of anal sphincter of seniles.However, the satisfactory rectal double balloon catheter has been improved after the clinical practice since 1973.This catheter is taken care of the followings :(1) not to be disconnected from the rectal tube(2) without a backflow of contrast media or air(3) to be capable of infusion or excretion of contrast media or airThe catheter has two holes, the one is at the oral side and the other at the anal side on the external anal sphincter for the anatomical rescribed above (1) (2).The infusion of contrast media or air is from the center tip of the catheter.The distance between two inflated balloons is 12 mm. The distance from the tip of the catheter to the oral sided balloon is 35 mm and the size of a hole for infusion and excretion is 10 mm × 10 mm in diameter. Two different sizes of the catheter which are respectively 10 mm and 14 mm in diameter available for any aged patients.Results : These double balloon cathers were applied for 39 cases and then the capacity of air infused was approximately 20 to over 20 ml. No abnormality or trouble were observed while use of this, catheter with air of 20 ml also in other 281 cases of 4 hospitals.
