[0014] Beneficial Effects

[0015] The utility model provides a blocking rectal diversion system. Compared with the prior art, it has the following beneficial effects:

The first balloon 4 is arranged at the end of the lower end of the catheter 1, and the second balloon 5 is arranged on the outside of the catheter 1 and above the first balloon 4.

[0027] A drug injection pipe 9 is arranged in the wall of the catheter 1, and a water injection pipe 8 is arranged on the inner wall of the catheter 1. The lower end of the catheter 1 is open, and a water injection port 82 and a drug injection port 92 are arranged on the inner side of the lower end opening of the catheter 1. One end of the water injection pipe 8 is connected to the water injection port 82, and the lower end of the water injection port 82 is arranged horizontally with the lower end of the catheter 1, and is arranged in a smooth transition with the inner side of the lower end of the catheter 1. The other end of the water injection pipe 8 extends to the outer side of the catheter 1 and is provided with a first common joint 81 with a cover. The water injection pipe 8 is preferably made of a polymer material, and one end of the drug injection pipe 9 and the injection port 82 are connected. The medicine ports 92 are connected to each other, the lower end of the injection port 92 is horizontally arranged with the lower end of the catheter 1, and is smoothly transitioned with the inner side of the lower end of the catheter 1. The other end of the injection tube 9 extends to the outer side of the catheter 1 and is provided with a one-way valve joint 91. During the indwelling process, if the catheter 1 is blocked, the patient's intestine is flushed and sucked through the water injection tube 8. If necessary, the irrigation step is repeated to completely eliminate the blockage. If rectal medication is required, the patient is adjusted to a lateral or prone position, and the drug solution is slowly injected into the rectum through the injection tube 9 and the injection port 92.

[0028] The inner wall of the catheter 1 is provided with a drainage tube 10, and the surface of the catheter 1 is provided with a drainage port 102 between the first balloon 4 and the second balloon 5. The drainage port 102 is connected to one end of the drainage tube 10, and the other end of the drainage tube 10 extends to the outside of the catheter 1 and is provided with a second common joint 101 with a cover. The drainage tube 10 is preferably made of a polymer material;

[0029] The first balloon 4 and the second balloon 5 are preferably made of polyurethane. An elastic reinforcing member 12 is embedded in the wall of the catheter 1. The main body of the elastic reinforcing member 12 is a spiral structure, and the material is a polymer material or stainless steel. The balloon wall thickness is 0.025 mm. After the air in the first balloon 4 and the second balloon 5 is exhausted as much as possible, the medical staff can apply lubricant on the surface of the first balloon 4 and the second balloon 5, and gently insert the first balloon 4 and the second balloon 5 into the rectum. Then the medical staff can use a syringe to insert the first one-way valve 62 or the second one-way valve 72, and fill the first balloon 4 or the second balloon 5 through the first injection tube 6 or the second injection tube 7 (the first balloon 4 or the second balloon 5 is filled with air). The filling medium may be water or air) to inflate the balloon, and then gently pull the catheter 1 to fix the inflated balloon to the ampulla of the rectum, ensuring that there is no gap between the balloons and that they are close to the bottom of the anus. The first balloon 4 and the second balloon 5 are not filled at the same time, but are filled in rotation. By filling the first balloon 4 and the second balloon 5 in rotation, compression on the same retention site is avoided. During the rotation filling of the first balloon 4 and the second balloon 5, after the first balloon 4 is filled, the waste liquid and feces between the first balloon 4 and the second balloon 5 are discharged through the drainage port 102, and then the second balloon 5 is emptied, which can avoid leakage of feces during the rotation filling process.

[0030] When in use, the catheter 1 is connected to the drainage tube 2 through a joint, and the other end of the drainage tube 2 is connected to the stool collection bag 3 through a joint to achieve rapid assembly of the barrier rectal diversion system. After the air in the first balloon 4 and the second balloon 5 is exhausted as much as possible, the medical staff can apply lubricant on the surface of the first balloon 4 and the second balloon 5, and gently insert the first balloon 4 and the second balloon 5 into the rectum. Then the medical staff can use a syringe to insert the first one-way valve 62 or the second one-way valve 72, and inject the first balloon 4 or the second balloon 5 into the rectum through the first injection tube 6 or the second injection tube 7. The balloon 5 is filled (wherein the filling medium can be water or air) to make the balloon filled and expanded, and then the catheter 1 is gently pulled to fix the expanded balloon to the rectal ampulla to ensure that there is no gap in the balloon and it is close to the bottom of the anus. The first balloon 4 and the second balloon 5 are not filled at the same time, but are filled in rotation. By filling the first balloon 4 and the second balloon 5 in rotation, the pressure on the same indwelling part is avoided. During the process of filling the first balloon 4 and the second balloon 5 in rotation, after the first balloon 4 is filled, the space between the first balloon 4 and the second balloon 5 is drained through the drainage port 102. Waste liquid and feces are discharged, and then the second balloon 5 is emptied, which can avoid leakage of feces during the rotation filling process. During the retention process, if the catheter 1 is blocked, the patient's intestine is flushed and sucked through the water injection pipe 8. If necessary, the irrigation step is repeated to completely eliminate the blockage. If rectal medication is required, the patient is adjusted to a lateral or prone position, and the drug solution is slowly injected into the rectum through the injection pipe 9 and the injection port 92. Finally, when the catheter 1 needs to be removed, the medical staff uses a syringe to insert into the first one-way valve 62 or the second one-way valve 72 to discharge the medium in the balloon, and then removes it from the patient's anus. The catheter 1 can be taken out. The polyurethane ball material of the first balloon 4 and the second balloon 5 has a thinner wall than the balloons made of PVC and silicone, and has a higher fit with the intestine, which reduces the leakage of feces and liquid from the gap between the balloon and the intestinal wall, and can effectively reduce the pressure on the rectum, thereby improving the comfort of use. The elastic reinforcement member 12 in the catheter 1 elastically supports the catheter 1, thereby improving the patency of the inner cavity of the catheter 1, so that the catheter 1 will not collapse due to the prolonged retention time or the change of the patient's body posture during activities, thereby causing the inner cavity of the catheter to be blocked and drained.
