Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary consumables technology, specifically to an enema bag. Background Technology

[0002] A stoma is a surgical intervention that creates an artificial opening (a "stomach" or "stoma") through the abdominal wall, allowing the digestive tract to connect directly to the outside of the body. This procedure is widely used in the treatment of various diseases, including cancer, inflammatory bowel disease, and severe trauma, to ensure the safe removal of waste.

[0003] Temporary stoma surgery is particularly suitable for patients who need time to allow for the recovery of damaged digestive tract or who need to bypass the lesion area post-surgery. This type of surgery is commonly seen in the recovery phase following low anterior resection of rectal cancer, inflammatory bowel disease, severe abdominal trauma from traffic accidents, shootings, or stabbings, as well as complex anorectal surgeries. As a reversible treatment option, temporary stomas help relieve symptoms and promote tissue healing. Typically, after several weeks to months, the intestinal segments at both ends of the stoma are reconnected via a cloning procedure, restoring normal continuity of the digestive tract.

[0004] Before performing a temporary stoma reduction procedure, doctors typically administer repeated enemas to cleanse the distal intestine. This step is crucial to reduce the risk of infection during and after surgery and to facilitate a smooth procedure. Since there are no dedicated drainage tools, the current enema procedure involves making a small incision on the outside of the ostomy bag, directly opposite the stoma. A flushing tube is then inserted through the incision into the ostomy bag to flush the stoma, allowing the stool to be collected in the bag or drained through it. However, this method has its problems. The incision edges on the ostomy bag are often irregular and difficult to match with the diameter of the flushing tube, making it difficult to form an effective seal between the tube and the incision. If not properly controlled, loose stool can leak out from the incision edges during the enema. This not only contaminates the sheets and surrounding environment but is also difficult to clean and increases the risk of skin infection for the patient.

[0005] Therefore, how to design a consumable device that can effectively drain enema fluid and prevent loose stool from flowing out during repeated enemas is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the technical defects of the existing method of cutting and draining the ostomy bag, which is difficult to form an effective seal due to the irregular cut edge and mismatch with the flushing tube, resulting in the leakage of loose feces that contaminates the sheets and the surrounding environment and is difficult to clean.

[0050] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0051] This embodiment provides an enema bag, such as Figure 1-4 As shown, the ostomy bag includes: a main body, an annular tube, a sealing plate, and a fixing nut; wherein, the main body 1 of the ostomy bag has a cuttable hole 11 on the side near the human body, and an installation hole 12 is opened on the opposite side of the cuttable hole 11, the main body 1 of the ostomy bag is adapted to be fitted onto the stoma through the cuttable hole 11; the annular tube 2 is installed on the main body 1 of the ostomy bag through the installation hole 12, one end of which extends to the outside of the main body 1 of the ostomy bag, and the annular tube 2 has a through hole 21 in the middle; the sealing plate 3 is disposed on the outer end of the annular tube 2, the middle part of which is adapted to allow the flushing tube to pass through, and when the flushing tube is removed, the sealing plate 3 can automatically close the opening by its own elasticity and structural characteristics, achieving a natural and effective sealing effect; the fixing nut 4 is hollow and open at both ends, and is screwed onto the outer end of the annular tube 2, which can press and fix the sealing plate 3, and a first end cap 5 is provided on the free end of the fixing nut 4.

[0052] When using the enema bag of this embodiment, firstly, the cuttable hole 11 of the ostomy bag body 1 is cut according to the size of the patient's stoma. Then, the ostomy bag body 1 is fitted onto the stoma through the cuttable hole 11. Next, the first end cap 5 is opened and the irrigation tube is inserted. After passing through the sealing plate 3, the irrigation tube extends into the inside of the ostomy bag body 1 and is inserted into the patient's intestine through the stoma. Then, the enema equipment is started, so that the irrigation fluid is injected into the intestine through the irrigation tube for thorough irrigation. During the process, the intestinal contents flow naturally into the ostomy bag body 1 through the stoma for collection. Throughout the irrigation process, the sealing plate 3 forms a dynamic fit with the outer wall of the irrigation tube, effectively preventing the leakage of fecal matter from the bag. After irrigation, the irrigation tube is slowly pulled out. The sealing plate 3 immediately closes the opening under its own elasticity and finally closes the first end cap 5 to prevent fecal matter from flowing out. The enema bag of this embodiment can ensure that there is no leakage of enema fluid during the irrigation process, and it can close immediately after the irrigation tube is removed without overflowing. It can also maintain the integrity of the ostomy bag and can continue to be used without replacement, reducing nursing costs.

[0053] like Figure 2 As shown; the sealing plate 3 includes a fixing ring 6 and an opening / closing plate 7 integrally formed in the middle of the fixing ring 6; the opening / closing plate 7 has a cross-shaped opening 8, and the opening / closing plate 7 is divided into four openable and closable valves 9 through the cross-shaped opening 8. The valves 9 can form holes when expanded to allow the flushing tube to pass through, and when the flushing tube is pulled out, the valves 9 can close and seal the holes by their own elasticity.

[0054] like Figure 2 As shown, one end of the annular tube 2 is formed with a limiting ring 10, and the fixing ring 6 is fitted with the limiting ring 10; the fixing nut 4 has a first limiting inner flange formed inside the end near the first end cap 5, the fixing nut 4 is screwed to the annular tube 2, and the first limiting inner flange can press the sealing sheet 3 inward, thereby pressing and fixing the sealing sheet 3.

[0055] The method of using this new enema bag is as follows:

[0056] First, precisely cut the cuttable holes 11 on the ostomy bag body 1 according to the patient's stoma size, ensuring that the ostomy bag body 1 can be tightly and comfortably fitted onto the patient's stoma; this step is crucial as it directly affects the ostomy bag's seal and the patient's comfort. Next, gently fit the cut ostomy bag body 1 onto the patient's stoma through the cuttable holes 11, ensuring a tight fit between the ostomy bag body 1 and the skin around the stoma to prevent leakage during the enema. Then, open the first end cap 5 on the fixing nut 4, insert the flushing tube through the opening of the first end cap 5, pass the flushing tube sequentially through the fixing nut 4 and the cross-shaped opening 8 on the sealing plate 3, extend into the inside of the ostomy bag body 1, and then through the stoma into the patient's intestine; during this process, the sealing plate 3... The four valves 9 on the ostomy tube gradually expand as the tube is inserted, forming a hole for the tube to pass through. Then, the enema equipment is activated, and the pre-prepared lavage solution is injected into the patient's intestine through the lavage tube. During the enema, the lavage solution thoroughly flushes the intestine, while the contents of the intestine flow naturally into the ostomy bag body 1 through the stoma and are collected. At the same time, the valves 9 on the sealing plate 3 dynamically adhere to the outer wall of the lavage tube, effectively preventing the leakage of fecal matter from the ostomy bag body 1, ensuring the hygiene and safety of the enema process. After the enema is completed, the lavage tube is slowly withdrawn. As the lavage tube is withdrawn, the valves 9 on the sealing plate 3 quickly reset under their own elasticity, closing the hole previously formed by the lavage tube, and then closing the first end cap 5, so that the contents do not flow out. Example

[0057] This embodiment provides an enema bag, such as Figure 5-10As shown, it includes: an ostomy bag body, an annular tube, a sealing plate, a connecting nut, a tensioning sleeve, and a tightening nut; wherein, the ostomy bag body 1 has a cuttable hole 11 on the side closest to the human body, and an installation hole 12 is opened on the opposite side of the cuttable hole 11, the ostomy bag body 1 is adapted to be fitted onto the stoma through the cuttable hole 11; the annular tube 2 is installed on the ostomy bag body 1 through the installation hole 12, one end of which extends to the outside of the ostomy bag body 1, the annular tube 2 has a through hole 21 in the middle; the sealing plate 3 is disposed on the outer end of the annular tube 2, the middle part of which is adapted for the passage of the flushing tube, and when the flushing tube is removed, the sealing plate 3 can be secured by... The opening automatically closes due to its own elasticity and structural characteristics, achieving a natural and effective sealing effect. The connecting nut 13 has openings at both ends and is threaded to the annular tube 2, which can compress and fix the sealing sheet 3. The connecting nut 13 has a conical guide hole 131 inside. The tensioning sleeve 14 is conical and can be retracted into the conical guide hole 131. A tightening hole 15 is provided in the middle, which passes through both ends and is suitable for clamping and fixing the flushing pipe through the tightening hole 15. The tightening nut 16 is hollow and has openings at both ends. It is screwed to the other end of the connecting nut 13. Rotating it inward can tighten the tensioning sleeve 14 inward. The free end is provided with a second end cap 17 that can be opened and closed.

[0058] When using the enema bag 1 of this embodiment, firstly, cut the cuttable hole 11 of the bag body 1 according to the size of the patient's stoma, and then fit the bag body 1 onto the stoma through the cuttable hole 11; next, open the second end cap 17 and insert the irrigation tube. After the irrigation tube passes through the tightening hole 15 on the tension sleeve 14, it continues to pass through the sealing piece 3, extends into the inside of the bag body 1, and is inserted into the patient's intestine through the stoma; then, rotate the tightening nut 16 inward to push the tension sleeve 14 inward and hold the irrigation tube tightly in place. Then, the enema equipment is activated, allowing the rinsing solution to be injected into the intestines through the flushing tube for thorough rinsing. During this process, intestinal fecal matter flows naturally into the ostomy bag body 1 through the stoma for collection. Throughout the rinsing process, the sealing plate 3 dynamically adheres to the outer wall of the flushing tube, effectively preventing the leakage of fecal matter from the bag. After rinsing, the tightening nut 16 is unscrewed to release the fixation of the flushing tube, and the flushing tube is slowly pulled out. At this time, the sealing plate 3 immediately closes the opening under its own elasticity, and finally closes the second end cap 17 to prevent fecal matter from flowing out. The enema ostomy bag of this embodiment can effectively prevent the outflow of loose feces during enema, avoid environmental pollution, and ensure the stable fixation of the flushing tube, preventing it from slipping off. Moreover, it can quickly restore a sealed state after the flushing tube is removed, maintaining the integrity of the ostomy bag for continued use, reducing the economic burden on patients and the complexity of nursing work.

[0059] like Figure 6As shown, the sealing plate 3 includes a retaining ring 6 and an opening / closing plate 7 integrally formed in the middle of the retaining ring 6; the opening / closing plate 7 has a cross-shaped opening 8, and the opening / closing plate 7 is divided into four openable and closable valves 9 through the cross-shaped opening 8. The valves 9 can form holes when they expand to allow the flushing tube to pass through, and when the flushing tube is pulled out, the valves 9 can close and seal the holes by their own elasticity.

[0060] like Figure 6 As shown, the connecting nut 13 includes: a main body 18 and a connecting shaft 20, wherein the inner wall of the main body 18 is provided with an internal thread, and is screwed to the annular tube 2 through the internal thread, and a second limiting inner flange 19 is formed on the inner wall of the end of the main body 18 away from the annular tube 2; the connecting shaft 20 is integrally formed on the second limiting inner flange 19, and an external thread is provided on the outer circumferential wall, and the tapered guide hole 131 is formed in the connecting shaft 20.

[0061] like Figure 9 As shown, one end of the annular tube 2 is formed with a limiting ring 10, and the fixing ring 6 is fitted with the limiting ring 10; the main body 18 is screwed to the annular tube 2, and the sealing sheet 3 is squeezed inward by the second limiting inner flange 19, thereby squeezing and fixing the sealing sheet 3.

[0062] like Figure 7 As shown, the tensioning sleeve 14 has a plurality of openings 22, one end open and the other end closed, evenly spaced on it, with adjacent openings 22 having opposite opening directions. The alternating slit design of the openings 22 generates a uniformly distributed circumferential stress in the tensioning sleeve 14 when it contracts radially. This structure ensures uniform fixation and improves the firmness when gripping the flushing pipe.

[0063] like Figure 6 and Figure 9 As shown, the tensioning sleeve 14 is installed in the tapered guide hole 131. The tightening nut 16 rotates inward to push the tensioning sleeve 14 toward the narrow end of the tapered guide hole 131. The opening 22 is deformed and shrinks inward due to the constraint of the inner wall of the tapered guide hole 131, thereby reducing the diameter of the tightening hole 15 and achieving effective clamping and fixing of the flushing pipe.

[0064] like Figure 10As shown, it also includes a pressure pad 23, made of silicone, installed inside the ostomy bag body 1, suitable for pressing the stoma; the pressure pad 23 has an annular gasket 24 in the middle, and the annular gasket 24 has a central through hole 25; the other end of the annular tube 2 is provided with a limiting ring 26, and the annular gasket 24 is installed between the limiting ring 26 and the inner wall of the ostomy bag body 1, so that the pressure pad 23 is limited and fixed inside the ostomy bag body 1 by the limiting ring 26. When the irrigation tube is pulled out, the pressure pad 23 provides uniform and moderate pressure to the patient's stoma site, which can play a buffering and protective role, effectively absorbing and dispersing the external force generated by improper operation or accidental pulling, avoiding direct traction damage to the stoma, thereby significantly reducing the risk of pain or injury caused by operation to the patient and enhancing the safety of use.

[0065] The practical application of this enema bag is as follows:

[0066] First, precisely cut the cuttable hole 11 on the ostomy bag body 1 according to the patient's stoma size, ensuring that the ostomy bag body 1 can be tightly and comfortably fitted onto the patient's stoma. Next, gently slip the cut ostomy bag body 1 onto the patient's stoma through the cuttable hole 11. At this time, the pressure pad 23 inside the ostomy bag body 1 will conform to the stoma, providing cushioning and protection. Then, open the second end cap 17 and insert the irrigation tube through the opening of the second end cap 17, passing the irrigation tube sequentially through the tension sleeve 14. The cross-shaped opening 8 on the sealing plate 3, through the tight hole 15, extends into the interior of the ostomy bag body 1 and is ultimately inserted into the patient's intestine via the stoma. After the irrigation tube is inserted into the intestine, the tightening nut 16 is screwed inward. Tightening the nut 16 pushes the tensioning sleeve 14 towards the narrow end of the conical guide hole 131. Constrained by the inner wall of the conical guide hole 131, the opening 22 on the tensioning sleeve 14 deforms and contracts inward, thereby reducing the diameter of the tightening hole 15 and effectively clamping and fixing the irrigation tube. Subsequently, the enema equipment is started, and the... Pre-prepared irrigation fluid is injected into the patient's intestines through an irrigation tube. During the enema, the irrigation fluid thoroughly flushes the intestines, while fecal matter flows naturally into the ostomy bag body 1 through the stoma and is collected. Simultaneously, the valve 9 on the sealing plate 3 dynamically adheres to the outer wall of the irrigation tube, effectively preventing fecal matter from leaking out of the ostomy bag body 1, ensuring hygiene and safety during the enema process. After the enema, the tightening nut 16 is turned outward to release the fixation of the irrigation tube. At this time, the tensioning sleeve 14 will gradually release under its own elasticity. The tube gradually returns to its original state, and the diameter of the tightening hole 15 increases, making it easier to pull out the flushing tube. Then, press the pressure pad 23 to make it stick to the stoma and slowly pull out the flushing tube. The pressure pad can provide further protection and cushioning for the patient's stoma site, effectively absorbing and dispersing the external force caused by improper operation or accidental pulling, avoiding direct traction damage to the stoma. As the flushing tube is pulled out, the valve 9 on the sealing plate 3 will quickly reset under its own elasticity, closing the hole previously formed by the flushing tube. Then, close the second end cap 17 to prevent fecal matter from flowing out.
