Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a reinforced barrier rectal diversion system. Background Art

[0002] Fecal incontinence refers to the anal sphincter losing its ability to control the excretion of feces and gas. It is an abnormal condition of defecation disorder and a common symptom in patients with clinical emergencies, coma and paraplegia. The stool of patients with fecal incontinence is often watery or loose, which can easily cause redness, edema and ulceration of the skin around the anus, and can cause skin damage and pressure ulcers in the perineum and sacrum. Clinically, patients are given barrier rectal diversion system products for fecal drainage. The anal tube is inserted through the anus and fixed in the patient's rectum to drain fecal fluid out of the body.

[0003] The balloon material of the existing barrier rectal diversion system is usually PVC or silicone, and the balloon wall is thick, which has a poor fit with the intestine and is prone to leakage. At the same time, the catheter lacks a supporting structure, which makes it easy for the catheter to collapse due to prolonged retention time or changes in the patient's posture during activities, thereby blocking the drainage of the inner lumen of the catheter. Utility Model Content

The catheter is made of a polymer material, which facilitates assembly of the catheter, the drainage tube, and the stool collection bag.

[0007] Preferably, the balloon is made of polymer material, and the balloon wall thickness is 0.025 mm. Compared with balloons made of PVC and silicone materials, the balloon wall of polymer material is thinner and has a higher degree of fit with the intestine, thereby reducing 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.

[0008] Preferably, the other end of the injection tube extends to the outside of the catheter and is provided with an indicator balloon, and the lower end of the indicator balloon is connected to a balloon one-way valve to facilitate filling of the balloon.

[0009] Preferably, the lower end of the water injection port is horizontally arranged with the lower end of the catheter, and is smoothly transitioned to the inner side of the lower end of the catheter. The other end of the water injection pipe extends to the outside of the catheter and is provided with an ordinary covered joint. The water injection pipe is made of polymer material, which is convenient for injecting water into the catheter and the patient's intestine, flushing the patient's intestine, and preventing the catheter from being blocked.

Compared with PVC and silicone materials, the polymer material of the balloon 4 has a thinner wall, and has a higher degree of 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;

Then the medical staff can use a syringe to insert the balloon check valve 52, fill the balloon 4 through the injection tube 5 (wherein the filling medium can be water or air), so that the balloon 4 is filled and expanded, and then the catheter 1 is gently pulled to fix the expanded balloon 4 in the rectal ampulla, ensuring that the balloon 4 has no gaps and is close to the bottom of the anus, so as to achieve stable retention of the catheter 1. During the retention process, if the catheter 1 is blocked, the patient's intestine is flushed and suctioned through the water injection tube 6 and the water injection port 61. 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. , the liquid medicine is slowly injected into the rectum through the injection tube 7 and the injection port 71. When the catheter 1 needs to be taken out, the medical staff uses a syringe to insert into the balloon check valve 52 to discharge the medium in the balloon 4, and then takes out the catheter 1 from the patient's anus. Compared with PVC material and silicone material, the polymer material of the balloon 4 has a thinner balloon wall and a higher degree of fit with the intestine, which reduces the leakage of feces and feces from the gap between the balloon 4 and the intestinal wall, and can effectively reduce the pressure on the rectum, thereby improving the comfort of use. The spiral structure of the elastic reinforcement 8 is used to make the elastic reinforcement 8 evenly disperse the extrusion force on the catheter, improve the overall extrusion resistance of the catheter 1, and at the same time make it have better elasticity, realize elastic support for the catheter 1, thereby improving the patency of the inner cavity of the catheter 1, so that the catheter 1 will not cause the tube body to collapse due to the extension of the indwelling time or the change of the patient's body posture during activities, thereby causing the inner cavity of the pipeline to be blocked and drained.
