Description
An easy-to-replace stoma plug with odor-neutralizing function Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to an easily replaceable ostomy plug with an odor-neutralizing function. Background Technology
[0002] Colorectal cancer or other intestinal diseases can lead to anal dysfunction, requiring surgery to create an enterostomy (i.e., an artificial anus) in the abdominal wall. Post-surgery, the patient's feces exit through the enterostomy, resulting in loss of bowel control. The traditional method for managing excrement is to attach an ostomy bag to the stoma. However, the traditional method of using ostomy bags has the following problems:
[0003] 1. Cumbersome operation: When using an ostomy bag, patients need to cut the adhesive strip on the ostomy bag according to the shape of their stoma. Then, they need to fill the area around the stoma with anti-leakage paste and then stick the adhesive strip to the skin. The whole process is quite cumbersome and increases inconvenience for patients.
[0004] 2. Prone to leakage and skin damage: Commercially available adhesive patches are usually made of thicker materials with poor breathability. If the skin around the stoma is not smooth, the patch cannot adhere tightly, easily leading to leakage. Each time the ostomy bag is changed, the adhesive side attached to the skin around the stoma needs to be removed. After cleaning and disinfecting the skin around the stoma, a new ostomy bag is reattached. This repeated process can easily damage the skin around the stoma, causing redness, swelling, pain, and other problems.
[0005] 3. Impact on Quality of Life: Due to the irregular bowel movements associated with the stoma, excrement is constantly being expelled and stored in the ostomy bag. The weight, fluidity, and odor of this excrement significantly negatively impact the patient's life and mental well-being. Frequent ostomy bag changes increase the burden on the patient and may affect their social activities and mental health.
[0006] In summary, existing methods of using ostomy bags have several drawbacks, including cumbersome operation, non-breathable materials, potential skin damage, and significant impact on patients' quality of life. Summary of the Invention

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] The embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.
[0040] The stoma plug of this invention effectively solves the various inconveniences that patients undergoing enterostomy surgery currently experience when wearing ostomy bags in daily life and when traveling, as well as the impact on the skin around the stoma when changing ostomy bags.
[0041] As shown in Figures 1-3, this embodiment of the invention provides an easily replaceable stoma plug with deodorizing function. The stoma plug includes a base 100, a water-absorbing plug 200, and a water-absorbing and deodorizing component 300.
[0042] The water-absorbing and deodorizing component 300 is fixedly connected to the chassis 100, and the outer ring of the water-absorbing and deodorizing component 300 is sealed to prevent excrement from contaminating the patient's skin and clothing near the stoma.
[0043] The base plate 100 has a through hole in the middle for the passage of the enterostomy 400; the absorbent plug 200 includes a circular base plate 210 and a cylindrical plug body 220 fixedly connected. The outer diameter of the base plate 210 is larger than the outer diameter of the plug body 220. The base plate 210 is fixed inside the absorbent and deodorizing assembly 300, and the plug body 220 passes through the absorbent and deodorizing assembly 300 and is inserted into the patient's enterostomy 400.
[0044] The plug 220 absorbs water from the excrement and expands, thereby blocking the enterostomy 400.
[0045] The water-absorbing and odor-eliminating component 300 is provided with a water-absorbing component, an odor-eliminating component, and an exhaust component. The water-absorbing component is used to absorb the water overflowing from the water plug, the odor-eliminating component is used to absorb the odor of the excrement, and the exhaust component is used to expel the waste gas from the body.
[0046] As shown in Figure 1, the stoma plug base plate 100 of this embodiment is fixed to the patient's enterostomy. The absorbent plug 200 and the absorbent and deodorizing component 300 are combined to form a single unit. During replacement, the patient simply grasps the absorbent and deodorizing component 300, pulls it out along with the absorbent plug 200, and then inserts the new, pre-assembled absorbent plug 200 and absorbent and deodorizing component 300 into the enterostomy, and then adhesively fixes the absorbent and deodorizing component 300 to the base plate 100. Compared to traditional ostomy bags, the stoma plug of this embodiment has the following advantages:
[0047] (1) Easy to operate: The replacement process is simple and quick, and the time and frequency of excrement discharge can be controlled, reducing the inconvenience to patients.
[0048] (2) Skin protection: The base that adheres to the skin does not need to be replaced frequently, thereby reducing the irritation and damage to the patient's skin and improving the user experience.
[0049] (3) Odor control: The water-absorbing and odor-eliminating component includes an odor-eliminating component and an exhaust component, which can effectively absorb the odor of excrement and expel waste gas from the body, significantly improving the patient's quality of life.
[0050] (4) Easy to carry: The water-absorbing and deodorizing components and the water-absorbing plug are assembled together, and the water-absorbing and deodorizing components are sealed on the outside, making them easy to carry.
[0051] Through the above improvements, the embodiments of the present invention not only simplify the operation process of stoma care, but also improve the patient's comfort and quality of life.
[0052] In this embodiment of the invention, the chassis 100 includes a first membrane layer 110 and a second membrane layer 120; the first membrane layer 110 is a waterproof and breathable membrane, and the second membrane layer 120 is a plastic film; the outer surface of the first membrane layer 110 is fixedly connected to the inner surface of the second membrane layer 120, and the inner surface of the first membrane layer 110 is coated with medical adhesive and then attached to the skin around the patient's enterostomy 400; the outer surface of the second membrane layer 120 is fixedly connected to the water-absorbing and deodorizing component 300; the first membrane layer 110 and the second membrane layer 120 are respectively concentrically provided with a first through hole 111 and a second through hole 121; the enterostomy 400 passes through the first through hole 111 and the second through hole 121 sequentially from the side of the first membrane layer 110 near the patient's skin.
[0053] In this embodiment of the invention, the first membrane layer 110 is directly attached to the patient's skin. Therefore, the first membrane layer 110 is a soft, waterproof, and breathable membrane to protect the patient's skin and prevent moisture from penetrating to the skin around the stoma. The first membrane layer 110 and the second membrane layer 120 are firmly connected by bonding or physical heat pressing, ensuring a tight bond and forming a stable whole. Through this design, this embodiment of the invention not only effectively protects the patient's skin but also ensures the structural stability and user comfort of the chassis 100.
[0054] In this embodiment of the invention, the absorbent plug 200 is made of absorbent sponge material. Commonly used absorbent materials include, but are not limited to, PVA (Polyvinyl Alcohol) and PU (Polyurethan). When the patient's stoma discharges waste, the absorbent plug absorbs the water and expands, further blocking the stoma and preventing the discharge of dry waste. After a certain period of time, when the waste accumulates to a certain amount, the absorbent plug and the absorbent odor-eliminating component can be replaced to control the timing and frequency of waste discharge from the stoma patient. The base can be replaced as needed.
[0055] In this embodiment of the invention, the water-absorbing and odor-removing component 300 includes a third membrane layer 310, a water-absorbing ring 320, a sealing bag 330, an odor-removing pad 340, and a fourth membrane layer 350.
[0056] The inner surface of the third membrane layer 310 is fixedly connected to the side of the chassis 100 away from the patient's skin; the third membrane layer 310 is a waterproof membrane.
[0057] The sealing bag 330 is formed by pressing together an upper part 331 and a lower part 332 of the sealing bag; the side of the substrate 210 away from the plug 220 is fixedly connected to the inner surface of the upper part 331 of the sealing bag; the absorbent ring 320 is fixedly disposed between the upper part 331 and the lower part 332 of the sealing bag; the absorbent ring 320 is used to absorb water overflowing from the absorbent plug 200. In some embodiments of the present invention, the substrate 210 is fixed to the inner surface of the upper part 331 of the sealing bag by adhesive bonding, and the absorbent ring 320 is fixed to the inner surface of the lower part 332 of the sealing bag by adhesive bonding.
[0058] The absorbent ring 320, the lower part of the sealing bag 332, and the center of the third membrane layer 310 are respectively provided with a third through hole 321, a fourth through hole 333, and a fifth through hole 311; the plug 220 passes through the third through hole 321, the fourth through hole 333, and the fifth through hole 311 in sequence and is then inserted into the enterostomy 400.
[0059] In some embodiments of the present invention, the absorbent ring 320 is made of absorbent sponge material.
[0060] The odor-absorbing pad 340 is disposed on the outer surface of the upper part 331 of the sealed bag to absorb the odor of excrement; the fourth film layer 350 is disposed on the outer surface of the odor-absorbing pad 340; the size of the odor-absorbing pad 340 is smaller than that of the fourth film layer 350; the fourth film layer 350 fixes the odor-absorbing pad 340 to the outer surface of the upper part 331 of the sealed bag. In this embodiment of the invention, the side of the fourth film layer 350 opposite to the odor-absorbing pad 340 is coated with medical adhesive, which firmly fixes the odor-absorbing pad 340 to the surface of the upper part 331 of the sealed bag.
[0061] The upper part 331 of the sealed bag is provided with a sixth through hole 334. Odors are discharged outside the sealed bag 330 through the sixth through hole 334 and are absorbed by the odor-absorbing pad 340.
[0062] In some embodiments of the present invention, the odor-eliminating pad is a carbon felt, which has the advantage of strong adsorption capacity.
[0063] In this embodiment of the invention, the water-absorbing and odor-eliminating component 300 further includes a first liquid-repellent and breathable membrane 360;
[0064] The first hydrophilic and breathable membrane 360 is adhered to the sixth through-hole 334 on the inner or outer surface of the upper part 331 of the sealed bag. The size of the first hydrophilic and breathable membrane 360 is larger than the size of the sixth through-hole 334. The first hydrophilic and breathable membrane 360 is used to prevent liquid inside the sealed bag 330 from flowing out through the sixth through-hole 334 and to provide an outlet channel for gas inside the sealed bag 330.
[0065] As shown in Figure 2, in some embodiments of the present invention, the fourth membrane layer 350 is a waterproof and breathable membrane, and the water-absorbing and deodorizing component 300 further includes a second liquid-repellent and breathable membrane 370.
[0066] The fourth membrane layer 350 has a seventh through-hole 351. The second hydrophilic and breathable membrane 370 is adhered to the seventh through-hole 351 on the outer surface of the fourth membrane layer 350. The size of the second hydrophilic and breathable membrane 370 is larger than the size of the seventh through-hole 351. The seventh through-hole 351 and the second hydrophilic and breathable membrane 370 provide a gas output channel. As the outermost membrane layer of the stoma plug, the second hydrophilic and breathable membrane 370 also prevents external moisture from entering the stoma plug.
[0067] As shown in Figure 3, in some other embodiments of the present invention, the fourth membrane layer 350 is a microporous waterproof and breathable membrane. In the embodiment shown in Figure 3, gas is discharged through the fourth membrane layer 350. As the outermost membrane layer of the stoma plug, the fourth membrane layer 350, being a microporous waterproof and breathable membrane, can also prevent external moisture from entering the stoma plug.
[0068] The present invention has the following beneficial effects: The stoma plug of this solution includes a base plate, an absorbent plug, and an absorbent and deodorizing component. The absorbent and deodorizing component is fixedly connected to the base plate. The absorbent plug includes a fixedly connected base plate and a plug body. The base plate is fixed inside the absorbent and deodorizing component, and the plug body extends out from the absorbent and deodorizing component and is directly inserted into the patient's enterostomy. The absorbent and deodorizing component includes an absorbent part, a deodorizing part, and a venting part, which can absorb excess water and odor from excrement, and expel waste gas from the body. The base plate is fixed to the patient's enterostomy, and the absorbent plug and the absorbent and deodorizing component are fixedly assembled together. When changing, the absorbent and deodorizing component and the absorbent plug are pulled out together, and then the clean absorbent plug and the absorbent and deodorizing component assembled together are inserted into the enterostomy. The absorbent and deodorizing component is then adhered to the base plate. Compared with traditional ostomy bags, the stoma plug of the present invention is convenient to carry, simple to replace, can control the time and frequency of excrement discharge, and does not require frequent replacement of the base plate that adheres to the patient's skin, which is beneficial to protecting the patient's skin and improving the patient's user experience. In addition, the water-absorbing and deodorizing component includes a deodorizing component and a degassing component, which can absorb the odor of excrement, expel waste gas from the body, and improve the patient's quality of life.
