Description

A stoma base plate and stoma bag with built-in elastic adhesive Technical Field

[0001] This utility model relates to the field of medical stoma technology, specifically to a stoma base plate and stoma bag with built-in elastic adhesive. Background Technology

[0002] The widespread use of ostomy bags is crucial for the daily care of ostomy patients. As the core structural component of the ostomy bag, the ostomy baseplate's main function is to secure the bag and collect excrement or bodily fluids. A suitable ostomy baseplate needs to fit perfectly against the user's surrounding skin as much as possible to prevent leakage and contamination, while also reducing skin irritation and damage.

[0003] However, the adhesive pads of existing stoma baseplates on the market are usually made of relatively rigid fabric materials, such as non-woven fabric and silk fabric. These materials have poor elasticity and extensibility, and their texture can easily affect comfort after being applied to the skin. Furthermore, they are prone to peeling up during prolonged use, which greatly affects the overall fit and increases the risk of leakage.

[0004] In addition, the peeling edges of the adhesive patch result in it not adhering properly to the skin, which not only affects the user's freedom of movement, but also leads to frequent replacements and additional care procedures, increasing the difficulty and cost of care. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an ostomy base plate and ostomy bag with built-in elastic adhesive, which aims to solve the problems of insufficient fit, poor comfort and easy curling of existing ostomy base plates during use.

[0006] The present invention adopts the following solution:

[0007] This application provides an ostomy baseplate with built-in elastic adhesive, including a baseplate body and an adhesive element attached to the outer periphery of the baseplate body; the adhesive element includes an adhesive layer and an elastic film layer formed on the adhesive layer; the adhesive layer is at least partially attached to the outer periphery of the baseplate body and at least partially used for adhesion to the user's skin; the elastic film layer is configured to adaptively generate elastic deformation under external force, thereby making the adhesive layer more flexibly conform to the user's skin.

[0008] As a further improvement, the elastic film layer is attached to the side of the colloid layer away from the user's skin, and the colloid layer and the elastic film layer are stacked and correspond to each other.

[0009] As a further improvement, the elastic film layer is made of a soft plastic material with greater elasticity or extensibility than fabric materials.

[0010] As a further improvement, the soft plastic material is PE, PU, ​​PET, PVC, or BOPP.

[0011] As a further improvement, the soft plastic material is an elastic material with added plasticizers or toughening agents.

[0012] As a further improvement, the colloidal layer is a skin-friendly hot melt adhesive, or a pressure-sensitive adhesive, or a modified adhesive, or a hydrocolloid.

[0013] As a further improvement, the outer ring of the chassis body is provided with an annular connecting part; the adhesive part has an annular structure and an internal through hole, and the adhesive layer located in the inner ring is attached to the annular connecting part, correspondingly avoiding the outer ring of the adhesive layer for sticking to the user's skin.

[0014] As a further improvement, a release layer is also attached to the other side of the colloid layer; the release layer includes a first release paper defining an inner ring of the colloid layer and a second release paper defining an outer ring of the colloid layer, wherein the width of the second release paper is greater than the width of the first release paper.

[0015] As a further improvement, the second release paper consists of two C-shaped release papers, allowing the user to quickly tear off the second release paper.

[0016] This application also provides an ostomy bag, including a bag body and an ostomy base plate with an elastic adhesive that is detachably connected to the bag body; wherein the back of the base plate body is used to adhere to the user's skin, and the adhesive is disposed on the outer periphery of the front side of the base plate body by an adhesive layer.

[0017] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0018] 1. The stoma base plate with built-in elastic adhesive in this application has an adhesive component on the outer periphery of the base plate body. The adhesive layer and the elastic film layer of the adhesive component cooperate with each other, so that the adhesive layer can more flexibly fit the user's skin, while the elastic film layer can produce elastic deformation under the action of external force, thereby adapting to the user's skin movement, enhancing the fit, and greatly avoiding problems such as lifting or even falling off.

[0019] 2. Among them, the elastic film layer has good elasticity, which improves the flexibility and extensibility of the entire adhesive, and can adaptively adjust its shape with the slight movement of the user's skin, reducing the pulling effect on the skin, thereby improving wearing comfort and reducing the risk of skin irritation.

[0020] 3. Furthermore, because the elastic film layer can adapt to deformation under external force, it can form a tighter seal around the skin, preventing leakage of excrement. At the same time, it further enhances the flexible adhesion of the colloid layer, significantly improving the sealing effect of the chassis.

[0021] 4. In addition, because the elastic film layer can improve the conformity of the base, making it less prone to lifting or falling off, the frequency of stoma base replacement is reduced, the service life of a single use is extended, and the user's care costs and operational burden are reduced.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. Example

[0031] Referring to Figures 1 to 7, this embodiment provides an ostomy base plate with a built-in elastic adhesive, including a base plate body 1 and an adhesive component 2 attached to the outer periphery of the base plate body 1. The adhesive component 2 includes an adhesive layer 21 and an elastic film layer 22 formed on the adhesive layer 21. The adhesive layer 21 is at least partially attached to the outer periphery of the base plate body 1 and at least partially used for adhesion to the user's skin. The elastic film layer 22 is configured to adaptively undergo elastic deformation under external force, thereby making the adhesive layer 21 more flexibly conform to the user's skin.

[0032] The stoma base plate with built-in elastic adhesive, as described above, has an adhesive component 2 set on the outer periphery of the base plate body 1. The adhesive layer 21 and the elastic film layer 22 of the adhesive component 2 cooperate with each other, so that the adhesive layer 21 can more flexibly fit the user's skin, while the elastic film layer 22 can produce elastic deformation under the action of external force, thereby adapting to the user's skin movement, enhancing the fit, and greatly avoiding problems such as lifting or even falling off.

[0033] The elastic film layer 22 has good elasticity, which improves the flexibility and extensibility of the entire adhesive 2. It can adaptively adjust its shape according to the slight movement of the user's skin, reduce the pulling effect on the skin, thereby improving wearing comfort and reducing the risk of skin irritation.

[0034] Furthermore, because the elastic film layer 22 can adaptively deform according to external forces, it can form a tighter seal around the skin, preventing leakage of excrement. At the same time, it further enhances the flexible adhesion of the colloidal layer 21, significantly improving the sealing effect of the chassis.

[0035] In addition, since the elastic film layer 22 can improve the conformity of the base, making it less prone to lifting or falling off, the frequency of stoma base replacement is reduced, the service life of a single use is extended, and the user's care costs and operational burden are reduced.

[0036] It is worth noting that the colloid layer 21 with its own elastic film layer 22 is more flexible and fits the user's skin, which is more significant compared to existing fabric materials or other directly moldable hydrocolloids.

[0037] In this embodiment, the elastic film layer 22 is attached to the side of the colloidal layer 21 away from the user's skin, and the colloidal layer 21 and the elastic film layer 22 are stacked and correspond to each other. This effectively improves the overall stability of the colloidal layer 21, making it less prone to deformation or loosening during prolonged use, thus extending the service life of the stoma baseplate. Furthermore, the elastic film layer 22 can undergo elastic deformation under external force, thereby enhancing the flexible adhesion of the colloidal layer 21, allowing the stoma baseplate to fit more tightly to the user's skin, reducing the risk of leakage due to lifting or loosening, and improving sealing and reliability.

[0038] Understandably, since the colloidal layer 21 is in direct contact with the skin, while the elastic film layer 22 is located on the side of the colloidal layer 21 away from the skin, it can effectively avoid direct contact with the skin, reduce skin irritation, and at the same time maintain the softness of the colloidal layer 21, making the wearing experience more comfortable.

[0039] It should be mentioned that the application of the elastic film layer 22 makes the force on the colloid layer 21 more uniform in different areas, adapting to the dynamic changes of the user's skin. In addition, since the elastic film layer 22 covers the outside of the colloid layer 21, it can provide a certain degree of protection, reducing the impact of external pollutants on the colloid layer 21, preventing the colloid layer 21 from losing its adhesiveness due to long-term exposure, thereby extending its service life and reducing care costs.

[0040] In this embodiment, the elastic film layer 22 is a soft plastic material with greater elasticity or extensibility than fabric. The use of a soft plastic material with greater elasticity or extensibility than fabric provides stronger elasticity and adaptability compared to traditional non-woven or silk fabrics. Furthermore, the soft plastic material exhibits better deformation under external force, allowing the gel layer 21 to better conform to the user's skin, effectively reducing edge lifting and improving wearing comfort and stability.

[0041] In existing technologies, fabric materials, due to their low elasticity and extensibility, are prone to loosening or losing their fit after prolonged wear. In contrast, the soft plastic material in this embodiment is more elastic, adapting to different body shapes and skin textures. Even during user movement, the base maintains good fixation, reducing care problems caused by displacement or loosening.

[0042] Clearly, the elastic film layer 22 made of soft plastic provides better resilience under stress, allowing the stoma baseplate to fit more closely to the skin and enhance the seal. Furthermore, the soft plastic material has good flexibility, adapting to subtle skin movements and reducing pulling and friction, thus improving wearing comfort. Compared to traditional fabric materials, it is more durable, less prone to tearing or deformation, and has better waterproof performance, extending the lifespan of the stoma baseplate and reducing the need for frequent replacements.

[0043] Preferably, the soft plastic material is PE, PU, ​​PET, PVC, or BOPP. PE (polyethylene), PU (polyurethane), PET (polyethylene terephthalate), PVC (polyvinyl chloride), or BOPP (biaxially oriented polypropylene) are used as the soft plastic material for the elastic film layer 22. These materials have superior elasticity and extensibility, allowing them to better adapt to the skin contours of different patients, improving the fit of the stoma baseplate, and further effectively preventing edge lifting.

[0044] In other embodiments, the soft plastic material is an elastic material with added plasticizers or toughening agents. It should be noted that plasticizers can reduce the material's hardness and increase its softness, making it more conformable to the skin's contours, thereby improving the fit of the stoma baseplate and reducing the risk of lifting or detachment. Alternatively, adding toughening agents can improve the material's ductility and tear resistance, allowing the elastic film layer 22 to better stretch and recover under external force, enhancing the stoma baseplate's adaptability to different body shapes and activity levels, and reducing displacement or loosening caused by body movements. Since traditional plastic materials are relatively rigid, the addition of plasticizers makes the material softer, reducing friction with the skin, thereby improving wearing comfort and reducing discomfort caused by prolonged use. Furthermore, toughening agents can improve the material's feel, making it closer to the softness of human skin, enhancing the user experience.

[0045] In this embodiment, preferably, the colloid layer 21 is a skin-friendly hot melt adhesive, pressure-sensitive adhesive, modified adhesive, or hydrocolloid. In the prior art, in order to make the colloid layer 21 fit the user's skin better, water-based acrylic adhesive is generally selected. Although it improves the flexible fit to a certain extent, it is very easy to cause allergic reactions after use, affecting the user's daily life.

[0046] In this embodiment, a more skin-friendly hot melt adhesive, pressure-sensitive adhesive, or modified adhesive is selected as the material for the colloid layer 21. It has better biocompatibility, is gentler on the skin, and can effectively reduce skin allergies, redness, or irritation caused by prolonged wear, thereby improving wearing comfort.

[0047] Among them, pressure-sensitive adhesive has excellent adhesion properties, which can generate strong adhesion when it comes into slight contact with the skin, so that the stoma baseplate can be quickly fixed on the skin, reducing the problem of loosening caused by movement or external force, and ensuring wearing stability.

[0048] Among them, modified adhesives and hydrocolloids, through formulations with additives and other means, improve adhesion strength and durability, and can maintain good fixation for a long time, reducing curling or detachment caused by decreased adhesion.

[0049] Hot melt adhesive has good moisture resistance and is not easily affected by changes in sweat, body fluids or environmental humidity. Its water resistance is even better, which helps to maintain the sealing of the stoma base, reduce the risk of leakage, and improve the safety of care.

[0050] As shown in Figures 2 to 6, in this embodiment, the outer ring of the chassis body 1 is provided with an annular connecting portion 11. The adhesive component 2 has an annular structure and an internal through hole 23. The adhesive layer 21 located in the inner ring is attached to the annular connecting portion 11, correspondingly avoiding the outer ring of the adhesive layer 21 used for adhesion to the user's skin. By providing an annular connecting portion 11 on the outer ring of the chassis body 1 and using the annular adhesive component 2, it is possible to ensure that the adhesive component 2 and the chassis body 1 are more firmly bonded together, improving the connection stability of the overall structure, reducing loosening caused by pulling or movement, and enabling the stoma chassis to adhere more firmly and reliably to the skin.

[0051] Furthermore, the inner ring of the gel layer 21 can adhere to the base body 1, while the outer ring of the gel layer 21 is designed to directly adhere to the skin, preventing overall displacement of the gel layer 21, making it softer and more conforming to the body's curves, significantly improving wearing comfort. At the same time, the distinct and mutually defining structures provide a better seal, effectively preventing leakage of excrement from the stoma, reducing the risk of contamination during care, and improving the sealing and safety of the ostomy bag.

[0052] Furthermore, the stoma baseplate also includes a release layer attached to the other side of the adhesive layer 21. The release layer includes a first release paper 24 defining the inner ring of the adhesive layer 21 and a second release paper 25 defining the outer ring of the adhesive layer 21, with the width of the second release paper 25 being greater than the width of the first release paper 24. When installing the stoma baseplate, the first release paper 24 can be peeled off first to fix the inner ring of the adhesive layer 21 to the annular connecting portion 11, ensuring accurate adhesion to the baseplate body 1. Then, the second release paper 25 can be peeled off to achieve a tight fit between the outer ring of the adhesive layer 21 and the skin. This step-by-step application method reduces the possibility of misoperation and improves the accuracy and convenience of use.

[0053] In particular, the width of the second release paper 25 is greater than that of the first release paper 24, which allows the outer layer of adhesive 21 to be evenly adhered to the skin at the end, avoiding problems such as folding, wrinkling or curling caused by one-time adhesion, thereby improving the fixation stability of the stoma base and ensuring a tight fit even during long-term use.

[0054] Specifically, the second release paper 25 consists of two C-shaped release papers, allowing the user to quickly tear it off. The two C-shaped release papers allow the user to tear them off simultaneously or separately from the left and right sides. Compared to a single sheet of release paper, this allows for faster and more convenient tearing and pasting of the outer ring, significantly improving efficiency, especially suitable for patients with limited mobility or those operating with one hand. Furthermore, this segmented tearing method allows the user to gradually adjust the fit of the entire stoma baseplate, tearing and pasting one side first, then tearing the other side, ensuring precise fit and avoiding misalignment, wrinkles, or air bubbles caused by tearing off all at once.

[0055] As shown in Figure 5, preferably, the thickness of the elastic film layer 22 is more than twice the thickness of the colloid layer 21. A thicker elastic film layer 22 can significantly improve the flexibility and extensibility of the entire adhesive 2, so as to achieve better elastic deformation capability.

[0056] In addition, this embodiment also provides an ostomy bag, including a bag body (not shown) and an ostomy base plate with a built-in elastic adhesive that is detachably connected to the bag body. The back of the base plate body 1 is used to adhere to the user's skin, and the adhesive component 2 is overlapped and disposed on the outer periphery of the front side of the base plate body 1 via an adhesive layer 21.

[0057] The ostomy bag described above can be detachably fitted to the base plate 1 and the bag body. Users can replace the bag body separately without replacing the base plate, thereby reducing the discomfort and economic burden caused by frequent replacement of the ostomy base plate, and improving the service life and care convenience of the ostomy bag.

[0058] Furthermore, the back of the chassis body 1 is fitted to the user's skin, and the adhesive 2 is attached to the outer periphery of the front of the chassis body 1 through the adhesive layer 21, which can ensure a close fit between the chassis body 1 and the skin. At the same time, by utilizing the adaptive deformation capability of the entire elastic adhesive (the adhesive layer 21 with the elastic film layer 22), a good fit and sealing effect are maintained during activities to prevent leakage of excrement and improve the safety of care.

[0059] In particular, the elastic film layer 22 of the adhesive component 2 is formed on the gel layer 21, which can better conform to the skin, providing a softer and more comfortable wearing experience, avoiding skin friction and irritation caused by edge lifting or excessive hardness, and is suitable for long-term wear. Furthermore, the gel layer 21 overlaps the outer periphery of the front of the base body 1, making the overall structure of the ostomy bag more stable, effectively reducing the risk of displacement and detachment caused by movement or pulling, and improving the reliability of the ostomy bag.
