[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0030] Enema is a method of injecting a certain amount of liquid from the anus through the rectum into the colon to help patients clean the intestines, defecate, pass gas, or supply drugs or nutrition from the intestines to achieve the purpose of diagnosis and treatment. In clinical practice, enema bags, urinary catheters, disposable anal tubes and other medical tools are often used to transport a certain amount of liquid through the anus and rectum to the colon to stimulate colon peristalsis, relieve constipation and intestinal flatulence, remove intestinal toxins, clean the intestines, prepare for surgery, and inject low-temperature liquids to cool down patients with high fever.

[0031] The existing disposable anal tube is shown in the utility model patent with application number: 202321080149.6: Disposable Multifunctional Anal Tube. A medicine outlet is provided on the side wall of the inlet end of the anal tube body, a positioning air bag is provided at the inlet end of the anal tube body, and a medicine inlet tube connected to the medicine outlet and an air inlet tube connected to the positioning air bag are provided on the inner side wall of the anal tube body, so as to realize the medicine injection and water injection functions of the anal tube and ensure the fixed position of the anal tube in the anus through the positioning air bag.

[0032] Since a small amount of liquid is often discharged through the patient's anus during enema, the above-mentioned utility model patent does not have a fecal storage device. During enema, the patient needs to bend his knees and lie on his side on the bed. At this time, the medicine, fecal water, etc. discharged from the anus will contaminate the bed sheets, increasing the workload of medical staff in changing and washing the sheets, and will also increase the psychological burden of the patient, which is not conducive to the patient maintaining a calm and relaxed state during the enema process; if the air pressure in the patient's intestine is high, excrement such as the irrigation fluid will splash from the anus, and the splashing range of the excrement is difficult to predict, which requires a high level of proficiency of medical staff and is easy to cause secondary infection to medical and patient staff, posing a certain risk.

[0033] In order to solve the above-mentioned technical problems, the utility model provides a disposable closed anti-leakage multi-channel anal tube to solve the technical problems that the existing anal tube is not provided with a feces storage device, and the discharge of excrement from the anus poses a risk of secondary infection to medical staff and patients, and the excrement will contaminate bed sheets, increasing the workload of medical staff in changing and washing bed sheets.

[0034] See also Figure 1-Figure 4 A disposable closed anti-leakage multi-channel anal tube comprises an anal tube body 1 and a collecting bag 2, wherein the collecting bag 2 is sealedly sleeved on one end of the anal tube body 1; an end of the anal tube body 1 away from the collecting bag 2 is an inlet end, a plurality of water outlets 3 are provided on the inlet end of the collecting bag 2, and a water inlet pipe 4 connected with the water outlet 3 is provided on the inner wall of the anal tube body 1; a positioning air bag 5 is provided at a position between the inlet end of the anal tube body 1 and the water outlet 3, and an air inlet pipe 51 connected with the positioning air bag 5 is provided on the inner wall of the anal tube body 1.

[0035] The use principle of the anal tube in the present application is as follows: the medical staff prepares enema equipment, such as the anal tube body 1, lubricating liquid, enema liquid, etc. The medical staff reminds the patient to find a comfortable position, usually lying on his side or lying on the bed; the medical staff cleans the skin around the patient's anus; the enema liquid is heated to a suitable temperature and filled into the enema bag; a lubricant is applied to the end of the anal tube body 1, the patient is reminded to relax, the anal tube body 1 is slowly inserted into the anus, the positioning balloon 5 is expanded to a suitable size by blowing gas into the air inlet pipe 51, and the liquid in the enema bag is slowly injected into the intestine through the water inlet pipe 4; when the liquid in the enema bag is completely injected, the enema liquid needs to be retained in the patient's body for a certain period of time, at which time some excrement will overflow from the anus, and the excrement can flow into the collection bag 2 along the anal tube body 1, avoiding environmental pollution during the retention stage of the enema liquid in the patient's body; then, the patient can go to the bathroom to defecate.

[0036] By sealing the collection bag 2 on one end of the anal canal body 1, it can be ensured that the excrement can smoothly enter the feces storage bag 6. This can effectively prevent leakage or leaking, keep the surrounding environment clean, and reduce the workload of medical staff in changing and washing bed sheets; the positioning airbag 5 can help the anal canal body 1 maintain a stable position during use, ensuring that the feces storage bag 6 can correctly collect excrement. This can improve the comfort and convenience of use; the setting of the air inlet pipe 51 can help adjust the inflation volume of the positioning airbag 5 to meet the needs of different individuals and improve comfort.

[0037] Since the single-layer collection bag 2 has the risk of rupture, if the collection bag 2 ruptures, the workload of medical staff will increase, and at the same time, it will cause greater pollution to the hospital environment. Based on this, in one embodiment, the collection bag 2 is a double-layer structure, and the collection bag 2 includes a feces storage bag 6 and an outer sealing bag 7. The feces storage bag 6 is sleeved on one end of the anal canal body 1, and the outer sealing bag 7 is coated on the outside of the feces storage bag 6 and is connected to the anal canal body 1 with a retractable drawstring 8. The outer sealing bag 7 can effectively cover the feces storage bag 6 to prevent excrement from leaking or polluting the surrounding environment, further ensuring the cleanliness and hygiene of the use environment; the outer sealing bag 7 can serve as a protective layer to reduce the contact between the feces storage bag 6 and the excrement, thereby reducing the difficulty of cleaning. Once use is finished, the fecal storage bag 6 can be easily cleaned by simply removing the outer sealed bag 7; the retractable drawstring 8 of the outer sealed bag 7 can be adjusted according to personal needs to ensure that the connection between the collecting bag 2 and the anal canal body 1 is tight and comfortable to avoid discomfort or leakage; at the same time, the fecal storage bag 6 is set to a transparent material, and medical staff can remove the outer sealed bag 7 during the enema process to observe the excrement in the fecal storage bag 6, and then judge the effect of the enema.

[0038] Some anal tubes commonly used in clinical practice are not provided with a positioning balloon 5. During enema, the positioning balloon 5 is easy to slip or even fall in the intestine, affecting the effect of enema; some are provided with a positioning balloon 5. After being inflated, the positioning balloon 5 is in the shape of a round cake. After being inflated, the contact area between the round cake-shaped positioning balloon 5 and the intestine is small, and the friction is insufficient. When the patient turns his body during enema or the anal tube body 1 is acted upon by external force, the positioning balloon 5 is easy to slide in the intestine. Since the positioning balloon 5 is in an inflated state, the squeezing effect on the intestine during sliding is large, which is easy to damage the intestine or even scratch the intestine. Based on this, in one embodiment, the positioning balloon 5 is cylindrical after being inflated and abuts against the inner wall of the patient's rectum. After being inflated, the positioning airbag 5 is set in a cylindrical state, and the circumferential side wall of the cylinder abuts against the inner wall of the intestine, which increases the friction between the positioning airbag 5 and the intestine and reduces the probability of the positioning airbag 5 moving in the intestine. At the same time, the positioning airbag 5 is set as a cylinder, which increases the receiving area between the positioning airbag 5 and the inner wall of the intestine. Under the pressure, the intestine is squeezed less, the patient's discomfort is less, which is conducive to improving the patient's enema experience.

[0039] The traditional anal canal is not provided with an anal canal fixing device or only with a group of anal canal fixing devices. If the anal canal fixing device is not provided, the anal canal is easy to fall off during the enema process. It depends on the manual fixing of the medical staff, which is not convenient for the medical staff to observe the excrement and the patient's condition. Only one group of anal canal fixing devices is easy to make the fixing device squeeze the intestine too much, thereby increasing the patient's discomfort during the enema process. Based on this, in one embodiment, an expansion sponge 9 is provided on the end of the anal canal body 1 away from the entrance end. The function of the expansion sponge 9 is to provide better stability and sealing during the insertion of the anal canal body 1. When the sponge expands, it can better fit the inner wall of the rectum, reduce the movement and sliding of the anal canal body 1 during insertion, and improve the stability of the operation. At the same time, the expansion sponge 9 can also improve the sealing between the anal canal body 1 and the rectum, help to avoid the overflow of the enema liquid, make the enema liquid fully contact with the intestine, and ensure the effect of the enema. Therefore, the design of the expansion sponge 9 can improve the comfort of the anal canal body 1 during the insertion process and the stability of the operation, while improving the sealing, thereby optimizing the effect and safety of the enema process. Since the end of the rectum is close to the anus, the sphincter on the anus will contract when stimulated and thus will be more sensitive. Compared with setting the expandable sponge 9 as an airbag structure, the expandable sponge 9 can change the size of the expansion according to the amount of overflowed enema liquid, making it more fit to the intestine, improving the enema effect and avoiding excessive stimulation of the rectum.

[0040] The anal tubes used clinically often have deficiencies in material. Some anal tubes are made of too hard a material, which can easily damage the tumor of rectal cancer patients and cause bleeding. Bleeding may cause tumor cells to spread in the blood, increase the risk of tumor metastasis, and may even require emergency surgery to control bleeding, increasing the risk and cost of treatment; some anal tubes are made of too soft a material, which is not easy to be fully inserted into the correct position during operation, which may cause the enema liquid to be unable to fully enter the intestine, affecting the effect of enema. Based on this, in one embodiment, the inlet end of the anal tube body 1 is made of silicone material with a hydrophilic coating. The setting of the silicone material with a hydrophilic coating can reduce the friction and stimulation of the anal and intestinal tissues during the insertion of the anal tube body 1, and reduce the discomfort and pain of the patient; the characteristics of the hydrophilic coating make the surface of the anal tube body 1 have a certain degree of lubricity, making it easier to insert into the correct position, which helps to improve the smoothness and accuracy of the operation; the silicone material with a hydrophilic coating can reduce the friction between the anal tube body 1 and the intestinal mucosa, making the enema process more comfortable; the silicone material has good biocompatibility, and the hydrophilic coating can reduce the attachment of bacteria and other pathogens on the surface of the anal tube body 1, reducing the risk of infection.

[0041] The entrance end of the common anal canal is straight, while the rectum is a multi-section curved intestine. The anal canal cannot fit the inner wall of the rectum, making it difficult for the enema liquid to penetrate into various parts of the rectum, affecting the effect of the enema. Based on this, in one embodiment, the entrance end of the anal canal body 1 is a wavy hose. The wavy hose can better fit the shape of the rectum, reduce the friction and stimulation of the rectum and anal tissues when the anal canal body 1 is inserted, thereby improving the patient's comfort; the wavy design can make the anal canal body 1 better fixed in the rectum during the insertion process, reduce movement and sliding, and improve the stability and accuracy of the operation; the wavy hose can better fit the rectal wall, improve the sealing between the anal canal body 1 and the rectum, help reduce the overflow of the enema liquid, and make the enema liquid fully contact with the intestine. In the field mirror of adding drugs to the enema liquid, it helps the drug liquid to fully act in the intestine, thereby improving the effect of the enema.

[0042] The water inlet pipe 4 in the common anal canal is usually connected to the water outlet 3 and the enema bag. By adjusting the opening and closing of the enema bag and the water outlet pressure, the water flow rate and water flow pressure of the enema liquid can be adjusted. However, when the amount of enema liquid in the intestine increases, the air pressure in the intestine is greater than the water outlet pressure of the enema bag, which can easily cause the enema liquid in the intestine to flow back along the water inlet pipe 4 to the enema bag, contaminating the enema bag and the enema liquid in the enema bag. Based on this, in one embodiment, a water inlet 10 is provided at one end of the water inlet pipe 4 away from the water outlet 3, and a first valve 11 is provided at the end of the water inlet 10, and the first valve 11 is a one-way valve. The first valve 11 is a one-way valve, which can control the pressure of the enema liquid input and the water flow rate. Medical staff or patients can adjust the pressure and water flow rate of the enema liquid according to their own conditions to achieve the best enema effect. The first valve 11 is set as a one-way valve to avoid the reverse flow of the enema liquid due to the high air pressure in the intestine, ensure the singleness of the enema liquid flow direction in the water inlet pipe 4, and ensure the enema effect.

[0043] The common positioning airbag 5 is inflated by a hand pump. Although it can save the inflation cost, different patients have different needs when using it. It is difficult for medical staff, especially patients, to control the inflation and deflation of the positioning airbag 5, which may easily lead to insufficient inflation and poor positioning effect, or excessive inflation, which will cause greater squeezing force on the intestine, excessive stimulation of the intestine and affect the effect of enema. Based on this, in one embodiment, a vent 12 is provided at one end of the air inlet pipe 51 away from the positioning airbag 5, and a second valve 13 is provided at the end of the vent 12, and the second valve 13 is a two-way valve. The second valve 13 is a two-way valve, which realizes the control of the inflation and deflation process of the positioning airbag 5. For different patients, the size of the intestine may be different, and for different patients, the position of the positioning airbag 5 is also different. Therefore, different patients need to select the positioning airbag 5 with a suitable inflation amount according to the situation. The setting of the two-way control valve facilitates medical staff and patients to control the inflation state of the positioning airbag 5.

[0044] When the enema is finished, the gas in the positioning airbag 5 is usually discharged directly. After the volume of the positioning airbag 5 is reduced, the anal canal body 1 is taken out from the intestine. The gas in the positioning airbag 5 may be mixed with excrement molecules in the intestine. If it is discharged directly, it may cause secondary infection to the patient and medical staff. Based on this, in one embodiment, the vent 12 is also sealed with an air storage bag 14. The setting of the air storage bag 14 realizes the collection of the gas in the positioning airbag 5. When the enema operation is finished, the ventilation direction of the second valve 13 is changed, so that the gas in the positioning airbag 5 is blown into the air storage bag 14 along the air inlet pipe 51, and the air storage bag 14 expands. Subsequently, the opening of the air storage bag 14 is sealed and treated as medical waste, which avoids the gas in the positioning airbag 5 from causing secondary infection to medical staff, realizes the collection of gas that may contain excrement molecules, and improves the safety of enema.

[0045] During the enema process, the patient may need to adjust his posture in order to achieve the best enema effect. During this process, the excrement in the feces storage bag 6 may flow back along the anal canal body 1, and the anal canal body 1 may be blocked. Based on this, in one embodiment, a valve 15 for limiting the one-way flow of excrement is provided at the inlet end of the feces storage bag 6. The provision of the valve 15 realizes the control of the one-way flow of excrement, avoids the excrement from flowing back to the anal canal body 1 or leaking out, avoids the excrement in the feces storage bag 6 from polluting the environment, ensures the cleanliness and hygiene during the enema process, and improves the smoothness of the enema process.
