DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contrast material such as Ba solution from the anus into the rectum, which is used for the treatment of rectal suturing failure which occurs as a complication after rectum surgery and for X-ray imaging of the rectum. The present invention relates to a rectal catheter which can be used for injecting air, discharging intestinal matter, contrast medium, and air.

[0002]

BACKGROUND OF THE INVENTION After rectal surgery, rectal suture failure often occurs as a complication. In addition, conventionally, the rectum, etc.
A rectal catheter used for injecting a contrast agent such as Ba solution from the anus into the intestine during radiography has been proposed. In such rectal catheters, generally, no balloon is formed inside the catheter body.

[0003]

However, once rectal suture failure occurs, not only the length of hospital stay is prolonged, but also a colostomy may be required. When a balloon is not formed inside the catheter body as in the rectal catheter, the rectal catheter is not fixed in the intestine and is not stabilized. As a result, the rectum and the like cannot be reliably X-rayed, and an accurate diagnosis cannot be made. The present invention has been made in order to solve the above-mentioned conventional problems. When rectal suture failure occurs as a complication after rectal surgery, a rectal catheter having a balloon formed inside the catheter body is inserted into the intestine into the anus. By inserting from the drug solution and discharging the drug solution near the lesion site from the drug solution outlet, it is possible to reliably treat rectal suture failure,
This makes it possible to reduce the pain of the patient. In addition, when X-ray imaging of the rectum, etc., when injecting a contrast medium such as Ba solution into the intestine from the anus, the rectal catheter should be fixed in the intestine by the balloon formed inside the catheter body to achieve stability. Therefore, an object of the present invention is to provide a rectal catheter which can reliably perform X-ray imaging and can accurately diagnose a rectum or the like and which is excellent in hygiene.

[0004]

Excretion port at the distal end communicating with the intestinal excretory passage (10)
(7) a rectal catheter having an inflatable balloon formed on an outer peripheral wall of a distal end portion of the catheter body;
At least one inflatable balloon formed on the outer peripheral wall of the catheter body at a position separated from the balloon by a predetermined distance, and another intestinal excretory passage inside the catheter body.
(30) is provided, wherein two of the at least one provided the chemical or chemical communicating with the contrast injection channel or contrast agent delivery port during the balloon, further between the two balloons, the <br/> intestine An excretion opening (29) communicating with the excretory passageway (30) and excreting intestinal excrement is provided , and is in communication with the excretion opening (7) at the tip.
Connect the intestinal excretion passage (10) and the excretion opening (29) between the balloons.
A rectal catheter characterized by having two excretory passages, including an intestinal excretory passage (30) .

[0005]

According to the present invention, the distal end of the rectal catheter is inserted into the anus while the balloon is deflated, and the distal end of the rectal catheter is fixed to the anus. At least one inflatable balloon formed on the outer peripheral wall of the catheter body is inflated by air pumped from the air pressure passage and fixed in the intestine.
Similarly, the inflatable balloon formed on the outer peripheral wall of the distal end portion of the catheter body is inflated with the air fed from the air pressure feeding path to stop intestinal dirt flowing down from the upper part of the colon. Further, the liquid medicine or the liquid liquid guided through the contrast medium injection path is discharged to the lesion site from the liquid liquid or the liquid contrast medium discharge port opened between the two balloons. For this reason,
In the case of rectal suture failure treatment, fix the rectal catheter in the intestine to prevent vibration, stabilize the movement,
It is possible to prevent contamination of the lesion site and bacterial infection. Further, it becomes possible to clean and heal the lesion site, thereby avoiding the application of a colostomy, shortening the length of hospital stay, and thus reducing the pain of the patient. On the other hand, when the rectum is to be radiographed,
An X-ray image of a lesion site can be surely made, and an accurate diagnosis can be made. Furthermore, between the balloon formed in the catheter body, intestinal excrement was aspirated from the opened excretory opening in the intestine (29), it is excreted to the outside through the intestinal excretion path (30).
For this reason, it is possible to prevent contamination of the lesion site and bacterial infection.
