Description

Technical Field

[0001] The present invention relates to the technical field of medical treatment instruments, and in particular to a feces catheter with peristaltic automatic defecation. Background Art

[0002] In the healthcare field, stoma surgery is an important treatment for intestinal diseases such as rectal cancer and bladder cancer. Postoperatively, patients require assistive devices to manage excretion, with stoma bags being the most common choice. However, existing stoma bags present numerous issues in practical use, severely impacting patients' quality of life and care experience.

[0003] Changing an ostomy bag is a cumbersome operation, causing great inconvenience to patients and caregivers. When changing an ostomy bag, you need to carefully tear off the base plate adhered to the skin. A slight mistake during this process can cause skin damage due to pulling, causing pain or even infection. Furthermore, when changing an ostomy bag, the patient needs to expose their private parts, which puts a certain amount of psychological pressure on the patient. After the replacement is completed, the discarded ostomy bag must be properly disposed of, increasing the cost of care and the environmental burden.

[0004] The stoma bag is not securely fixed and is prone to detachment and leakage. The stoma bag is primarily secured to the patient's skin by an adhesive base, which can be affected by factors such as patient activity, sweating, and skin oil secretion, significantly reducing its effectiveness. For example, when a patient turns over in sleep, walks daily, or performs simple exercises, the stoma bag may shift due to insecure fixation, causing leakage. This can not only stain clothing and bedsheets, but can also irritate the skin around the stoma, leading to complications such as inflammation, increasing the patient's pain and the workload of caregivers.

[0005] Therefore, the present invention discloses a fecal catheter for peristaltic automatic defecation. Summary of the Invention

[0006] In order to achieve the above technical effects, the present invention is implemented through the following technical solutions:

[0007] A fecal catheter for peristaltic automatic defecation, comprising: a defecation tube, a plurality of annular extrusion bags, a flushing tube, an air tube, and a sealing head;

[0008] The defecation tube is hollow inside, and a detachable sealing head is installed at the front end of the defecation tube; a plurality of annular extrusion bags are arranged in an array inside the defecation tube, and a flushing tube and a trachea are embedded in the walls on both sides of the defecation tube respectively; adjacent annular extrusion bags are connected by bidirectional valves;

[0009] One end of the flushing tube passes through the annular extrusion bag connected to the rear end;

[0010] One end of the trachea is connected to the annular extrusion bag at the rear end;

[0011] Furthermore, the front end of the defecation pipe is threadedly connected to the head, and a fixing plate is provided at the front of the defecation pipe;

[0012] The fixing plate is provided with an adhesive layer for fixing the defecation tube on the surface of human skin;

[0013] Furthermore, the front end of the flushing pipe extends out of the front part of the defecation pipe and is detachably connected to the pump body for extracting the flushing liquid, and the front end of the flushing pipe is threadedly connected to the head 1, and the rear end of the flushing pipe passes through the annular extrusion bag at the rear end, and a telescopic tube is provided at the rear end of the flushing pipe to adapt to the expansion and contraction of the annular extrusion bag;

[0014] A one-way valve is provided at the end of the flushing pipe;

[0015] Furthermore, a defecation tube is extended from the front end of the trachea and is movably connected to an air pump for controlling the inflation and deflation of the annular extrusion bag, and a second threaded seal is provided at the front end of the trachea;

[0016] Furthermore, the sealing head, sealing head 1 and sealing head 2 are respectively connected with the defecation pipe, flushing pipe and trachea by threads to control the closing or opening of the defecation pipe, flushing pipe and trachea; the inner walls of the sealing head, sealing head 1 and sealing head 2 are all provided with a sealing coating;

[0017] Furthermore, the bidirectional valve is a bidirectional valve that opens and closes in both directions, that is, as long as the force or pressure on one side is greater than the force or pressure on the other side to a certain extent, the bidirectional valve can be opened to the side with greater force;

[0018] The beneficial effects of the present invention are:

[0019] The present invention discloses a fecal catheter for peristaltic automatic defecation, comprising: a defecation tube, a plurality of annular extrusion bags, a flushing tube, an air tube, and a sealing head. The defecation tube is placed in a human body, one end of the defecation tube is connected to the human intestine, and the defecation tube is fixed to the surface of the human stoma via a fixing plate. When defecation is not required, the sealing head, the first sealing head, and the second sealing head keep the defecation tube, the flushing tube, and the air tube sealed. When defecation is required, the sealing head and the second sealing head are opened, and the air tube is connected to an air pump. The air pump cyclically inflates and deflates the annular extrusion bags, controlling the annular extrusion bags to expand step by step from the end toward the head end, or to contract step by step from the head end toward the end, thereby simulating the peristaltic process of the human intestine, and allowing feces entering the defecation tube to be discharged from the human body along the defecation tube.

[0020] When the inside of the defecation tube needs to be cleaned, the annular extrusion bag is kept in a contracted state and the second seal is controlled to seal the trachea. The seals and the first seal are opened, and the head end of the flushing tube is connected to a pump body for extracting flushing liquid. The pump body is controlled to operate to inject liquid into the flushing tube. The flushing liquid is sprayed out through the end of the flushing tube to flush and clean the inner wall of the defecation tube. The flushing liquid is discharged from the body along the head end of the defecation tube, thereby cleaning the defecation tube.

[0021] After the defecation tube of the present invention is implanted, there is no need to frequently replace the ostomy bag. The patient only needs to perform simple connection operations when defecating and cleaning, such as connecting the air pump and the pump body, avoiding the tedious steps of tearing and sticking when replacing the ostomy bag, saving time and energy, and reducing the irritation to the skin around the stoma due to the replacement operation, thereby reducing skin damage, pain and infection risks.

[0022] Moreover, after the defecation tube of the present invention is fixed, the patient does not need to frequently expose the body during daily defecation and cleaning, which effectively protects the patient's privacy, maintains the patient's dignity, reduces the psychological burden, and improves the patient's quality of life and psychological comfort;

[0023] Moreover, the present invention promotes the excretion of feces through simulated intestinal peristalsis rather than relying on gravity and ostomy bag collection. In principle, it reduces the problem of excrement leakage caused by changes in body position, activities, etc., keeps the patient's body and clothes clean, reduces irritation to the skin around the stoma, and reduces the occurrence of complications such as inflammation.
