Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a stoma plug for easy replacement of stoma base plates. Background Technology

[0002] After colorectal cancer or small bowel cancer surgery, an ileostomy is required in the corresponding part of the body for waste drainage. An ileostomy is usually made by fixing the end of the small intestine to the abdomen through an abdominal opening to replace the large intestine, which is temporarily or permanently unable to function. It needs to be left in place for at least 3-6 months. The ileum has very low sensitivity to the urge to defecate. Because food in the ileum does not pass through the large intestine, it contains a lot of digestive enzymes and is continuously discharged, which is highly corrosive to the skin. In addition, the ileum does not have a concentrating function, and the excrement is thin and unformed. When the patient is not properly cared for or other uncontrollable reasons, the bottom plate of the ostomy bag may leak.

[0003] An existing patent publication number, CN207075952U, describes a replaceable ostomy bag plug, which includes a fixed base, a plug body, and a replaceable bag body. When the collection bag needs to be replaced, the replaceable bag body is unscrewed, the plug body is aligned with the stoma opening and inserted inside, and the plug body is fixed to the fixed base by the threads on the plug cap. A gap is left between the plug and the plug cap, the size of which is determined according to the intestinal wall thickness. The gap can accommodate the stoma extending from the spiral interface, preventing excrement from flowing out of the stoma opening during replacement. However, for ileostomies with thin and large amounts of excrement, if the plug body is directly aligned with the stoma opening and inserted inside, if there is a lack of absorbent material inside, intestinal fluid and other excrement will continuously flow out of the stoma uncontrollably during the replacement of the base, resulting in poor adhesion of the base and skin breakdown around the stoma. If the skin around the stoma is red, swollen, and broken, it will further affect the adhesion of the base, thus making it impossible to maintain adhesion and seriously affecting the patient's life. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a stoma plug for easy replacement of stoma base plates. The polyurethane foam column and alginate dressing strip in the moisture-absorbing plug assembly are pushed by the piston rod inside the outer plug tube, which have strong moisture absorption capacity and can quickly absorb intestinal fluid.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a stoma plug for easy replacement of stoma base plate, comprising an external plug tube for insertion into an ileostomy, wherein a piston rod for pushing is inserted and installed inside the external plug tube, the piston rod being hollow and tubular, and a moisture-absorbing plug assembly for absorbing intestinal fluid is inserted and installed inside the piston rod; the moisture-absorbing plug assembly comprises a compression tampon column, a polyurethane foam column, an alginate dressing strip, a sterile cotton pad, and cotton thread, wherein the compression tampon column is inserted and installed close to the bottom end of the piston rod, the polyurethane foam column is fixedly installed in the middle of the bottom wall of the compression tampon column, the alginate dressing strip is wrapped around the outside of the polyurethane foam column, the sterile cotton pad is fixedly installed on the top wall of the compression tampon column, and the cotton thread is inserted and installed inside the compression tampon column and extends to the outside of the piston rod.

[0006] As a preferred embodiment of this invention, the alginate dressing strip is accordion-folded and included on the outer wall of the polyurethane foam column.

[0007] As a preferred embodiment of this utility model, the moisture-absorbing plug assembly is shaped like a bullet.

[0008] As a preferred embodiment of this utility model, the outer plug tube is made of smooth plastic material, and the bottom opening of the outer plug tube has an arc-shaped opening.

[0009] As a preferred embodiment of this utility model, a first handrail plate is sleeved on the top end of the outer bolt tube, and a second handrail plate is sleeved on the top end of the piston rod.

[0010] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0011] The absorbent plug assembly is pushed through a piston rod inside the external plug tube. The polyurethane foam column and alginate dressing strip have strong moisture absorption capabilities, which can quickly absorb intestinal fluid and keep the skin around the stoma dry and clean. The presence of sterile cotton pads helps reduce the risk of external infection around the stoma. The disposable external plug tube and absorbent plug assembly also avoid the possibility of cross-infection. The smooth design of the external plug tube and piston rod reduces friction with the skin around the stoma, improving patient comfort. The soft material of the absorbent plug assembly also reduces discomfort inside the stoma. By absorbing intestinal fluid in time, this stoma plug helps extend the life of the stoma baseplate and reduce the frequency and cost of replacement. Attached Figure Description

[0018] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a stoma plug for easy replacement of stoma base plates, including an external plug tube 1 for insertion into an ileostomy, a piston rod 2 for pushing is inserted into the external plug tube 1, the piston rod 2 is a hollow tube, and a moisture-absorbing plug assembly 3 for absorbing intestinal fluid is inserted into the piston rod 2; the moisture-absorbing plug assembly 3 includes a compression cotton swab column 31, a polyurethane foam column 32, an alginate dressing strip 33, a sterile cotton pad 34, and cotton thread 35. The compression cotton swab column 31 is inserted tightly into the bottom end of the piston rod 2, the polyurethane foam column 32 is fixedly installed in the middle of the bottom wall of the compression cotton swab column 31, the alginate dressing strip 33 is wrapped around the outside of the polyurethane foam column 32, the sterile cotton pad 34 is fixedly installed in the top wall of the compression cotton swab column 31, and the cotton thread 35 is inserted into the inside of the compression cotton swab column 31 and extends to the outside of the piston rod 2.

[0020] In this embodiment, the compressed cotton swab column 31 of the absorbent plug assembly 3 is tightly inserted into the bottom end of the piston rod 2, ensuring that the cotton thread 35 is correctly inserted into the compressed cotton swab column 31 and extends to the outside of the piston rod 2 for subsequent operation. The piston rod 2 with the absorbent plug assembly 3 installed is inserted into the outer plug tube 1, ensuring that the connection between the piston rod 2 and the outer plug tube 1 is tight and without looseness. The front end of the outer plug tube 1 is aligned with the ileostomy opening and gently pushed in. The piston rod 2 acts as a pushing tool to help accurately deliver the absorbent plug assembly 3 into the stoma. When the absorbent plug assembly 3 reaches the designated position, the piston rod 2 and the outer plug tube 1 are gently withdrawn, leaving the absorbent plug in the same position within the stoma. The compression tampon column 31 of component 3 is located at the bottom end of the absorbent plug component 3 and is tightly inserted into the piston rod 2, serving a supporting and fixing function. The polyurethane foam column 32 is fixedly installed in the middle of the bottom wall of the compression tampon column 31, possessing strong water-locking ability and effectively absorbing and locking in intestinal fluid. The alginate dressing strip 33 is tightly wrapped around the outside of the polyurethane foam column 32 in an accordion-like fold, further enhancing the moisture absorption capacity and rapidly absorbing several times its own weight in water, providing a time for interruption of flow when changing the stoma baseplate. The sterile cotton pad 34 is fixedly installed on the top wall of the compression tampon column 31, helping to reduce the risk of external infection around the stoma. The cotton thread 35 is inserted into the compression tampon column 31. The tampon tube 31 extends from the inside to the outside of the piston rod 2, facilitating the removal of the absorbent plug assembly 3 from the stoma when needed. The absorbent plug assembly 3 remains inside the stoma to absorb intestinal fluid. Apply a suitable amount of skin protectant around the stoma, and then attach the new stoma baseplate around the stoma, ensuring a secure fit. The absorbent plug assembly 3 can maintain its absorbency for a certain period. After replacing the stoma baseplate, gently pull the tampon 35 to remove the absorbent plug assembly 3 from the stoma. The outer plug tube 1, piston rod 2, and absorbent plug assembly 3 are all disposable; discard the used absorbent plug assembly 3. This stoma plug is rationally designed and easy to operate, making the process of replacing the stoma baseplate quicker and easier. Conveniently designed, the polyurethane foam column 32 and alginate dressing strip 33 in the absorbent plug assembly 3 have strong moisture absorption capacity, which can quickly absorb intestinal fluid and keep the skin around the stoma dry and clean. The presence of sterile cotton pads 34 helps reduce the risk of external infection around the stoma. The disposable external plug tube 1 and absorbent plug assembly 3 also avoid the possibility of cross-infection. The smooth external plug tube 1 and piston rod 2 design reduces friction with the skin around the stoma, improving patient comfort. The soft material of the absorbent plug assembly 3 also reduces discomfort inside the stoma. By timely absorbing intestinal fluid, this stoma plug helps extend the service life of the stoma baseplate and reduce the frequency and cost of replacement.

[0021] Specifically, the alginate dressing strip 33 is accordion-folded and included on the outer wall of the polyurethane foam column 32.

[0022] In this embodiment, the accordion-like fold structure of the alginate dressing strip 33 increases its contact area with intestinal fluid, thereby improving absorption efficiency. It can gradually expand after absorbing intestinal fluid, better conform to the shape of the stoma, and reduce intestinal fluid leakage. The accordion-like fold structure makes the alginate dressing strip 33 smoother during implantation and removal, reducing friction and irritation with the skin around the stoma.

[0023] Specifically, the moisture-absorbing plug assembly 3 is shaped like a bullet.

[0024] In this embodiment, the absorbent plug assembly 3 is bullet-shaped with a sharp front end for easy insertion into the stoma; the rear end gradually widens and is tightly connected to the piston rod 2. This design reduces the resistance during insertion while ensuring the stability of the absorbent plug assembly 3 within the stoma.

[0025] Specifically, the outer plug tube 1 is made of smooth plastic, and an arc-shaped opening 12 is provided at the bottom end of the outer plug tube 1.

[0026] In this embodiment, the external stent 1 is made entirely of plastic with a smooth surface, which reduces friction with the skin around the stoma, reduces skin irritation and discomfort. The smooth surface also helps to reduce resistance when inserting and removing the external stent 1, making the operation smoother. The bottom opening of the external stent 1 has an arc-shaped opening 12, which makes the external stent 1 more gentle when inserted into the stoma, reducing the potential damage of sharp edges to the stoma tissue. The arc-shaped opening 12 can also better fit the shape of the stoma, improve the sealing, and prevent intestinal fluid leakage.

[0027] Specifically, a first handrail plate 11 is fitted onto the top of the outer bolt tube 1, and a second handrail plate 21 is fitted onto the top of the piston rod 2.

[0028] In this embodiment, the first handrail 11 is sleeved on the outside of the top end of the external plug tube 1, providing a stable grip point for medical staff or patients, facilitating the insertion and adjustment of the position of the external plug tube 1. The second handrail 21 is sleeved on the outside of the top end of the piston rod 2, providing additional grip and operational stability, facilitating the pushing of the moisture-absorbing plug assembly 3. The design of the first handrail 11 and the second handrail 21 provides a stable grip point for medical staff or patients, enhancing the stability and accuracy of the operation.
