Description

Technical Field

[0001] This utility model relates to the field of ostomy bag base technology, and in particular to an ostomy bag base. Background Technology

[0002] The ostomy bag baseplate, also commonly known as the ostomy bag base or substrate, is a key component of the ostomy bag. It is attached directly to the patient's skin, surrounding the artificial opening (ostomy). Its main function is to secure and support the ostomy bag and provide a sealed environment to ensure that the ostomy bag can effectively collect excrement.

[0003] Currently, during the installation of the ostomy bag base plate, medical staff first need to use a special ruler to measure the diameter of the patient's stoma. Then, based on the size of the stoma diameter, the medical staff will use scissors to trim the through hole of the ostomy bag base plate. The trimmed base plate is then placed on the patient's stoma and attached to the patient's skin.

[0004] However, when medical staff trim the aperture of the base plate with scissors, manual trimming of the aperture cannot achieve a completely stable cut. This makes it easy for the aperture of the base plate to be too large or to be trimmed improperly. As a result, the through hole of the base plate cannot fit tightly around the enterostomy, which affects the sealing of the base plate and makes it easy for excrement to leak out from the gap. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the ostomy bag base plate has poor sealing effect in the prior art, which easily leads to leakage of excrement, and to propose an ostomy bag base plate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An ostomy bag baseplate includes a base plate with through holes on its surface and an adhesive area on the base plate. It also includes an elastic airbag fixedly connected to the base plate, wherein the elastic airbag has an annular cross-sectional shape and an elastic opening at its center, the elastic opening communicating with the through holes and having collinear axes; and an adjustment part disposed on the elastic opening, wherein the adjustment part is used to change the gas volume inside the elastic opening.

[0008] To improve the sealing effect of the elastic airbag, preferably, the adjusting part includes an airbag strip fixedly connected to the elastic airbag, the airbag strip being wound in a ring around the surface of the elastic airbag, wherein air holes communicating with each other are opened between the airbag strip and the elastic airbag, and a fixing layer is fixedly installed inside the airbag strip.

[0009] To bond the inner walls of the two sides of the airbag strip together, the fixing layer is made of strong double-sided adhesive and has a thickness of 0.5 mm to 1 mm.

[0010] To ensure that the elastic opening fits snugly around the enterostomy, both the elastic airbag and the airbag strip are made of rubber, and the wall thickness is 1 mm to 2 mm.

[0011] In order to bond the substrate to the patient's skin, preferably, the bonding area includes an adhesive layer disposed on the surface of the substrate, on which release paper is bonded.

[0012] To further protect the skin near the patient's stoma, the adhesive layer is made of water-based adhesive with a thickness of 0.3 mm to 1 mm.

[0013] To facilitate the peeling of the release paper from the adhesive layer, the size of the release paper is further larger than the size of the adhesive layer.

[0014] To ensure that the elastic opening can cover the patient's enterostomy, preferably, the diameter of the elastic opening is smaller than the diameter of the through hole.

[0015] To facilitate the passage of the colostomy through the elastic opening, preferably, the port of the elastic opening is chamfered, and the chamfer angle is between 15 and 35 degrees.

[0016] To facilitate the removal of the substrate adhered to the patient's skin, preferably, a pull tab is fixedly connected to the substrate, and the pull tab is integrally formed with the substrate.

[0017] Compared with the prior art, this utility model provides an ostomy bag base plate with the following features:

[0018] Beneficial effects:

[0019] 1. The ostomy bag baseplate, through the combined use of elastic airbags, elastic openings, and airbag strips, can ensure that the elastic opening fits tightly around the patient's enterostomy, thereby seamlessly wrapping the enterostomy and greatly improving the sealing effect of the ostomy bag baseplate, preventing excrement from leaking out from the gaps.

[0020] 2. The ostomy bag baseplate can control the expansion of the elastic airbag by pressing the airbag strip. The more the airbag strip is compressed, the larger the elastic airbag expands and the smaller the diameter of the elastic opening. By adjusting the size of the elastic opening, the applicability of the ostomy bag baseplate can be improved.

[0021] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model solves the problem in the prior art that the sealing effect of the ostomy bag base plate is poor, which easily leads to leakage of excrement. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Example:

[0032] Reference Figures 1-6This utility model provides an ostomy bag base plate, including a base plate 1 with through holes 2 on its surface. The base plate 1 can be made of foam, plastic or other durable materials. The base plate 1 has an adhesive area for fixing it to the patient's skin. A pull head 7 is fixedly connected to the base plate 1 and is integrally formed with the base plate 1, making it easy to peel off the base plate 1 completely from the patient's skin. It also includes: an elastic airbag 4, fixedly connected to the base plate 1. The elastic airbag 4 has an annular cross-sectional shape and an elastic opening 5 at its axis. The elastic opening 5 is interconnected with the through holes 2 and their axes are collinear. The diameter of the elastic opening 5 is smaller than the diameter of the through holes 2 to ensure that the elastic opening 5 can cover the patient's enterostomy. The end of the elastic opening 5 is chamfered with an angle of 15 to 35 degrees to guide the patient's enterostomy through the elastic opening 5. An adjustment part is provided on the elastic opening 5, which is used to change the gas volume inside the elastic opening 5.

[0033] Specifically, during use, the elastic airbag 4, the elastic port 5, and the air regulating part work together to ensure that the elastic port 5 fits tightly around the patient's stoma, thus seamlessly wrapping the stoma and greatly improving the sealing effect of the stoma bag base plate. This prevents excrement from leaking out from the gaps and also allows for control over the expansion size of the elastic airbag 4, which helps to broaden the applicability of the stoma bag base plate.

[0034] The adjustment part in the ostomy bag chassis includes an airbag strip 6 fixedly connected to the elastic airbag 4. The airbag strip 6 is arranged in a ring around the surface of the elastic airbag 4. There are air holes 61 that communicate with each other between the airbag strip 6 and the elastic airbag 4. A fixing layer 62 is fixedly installed inside the airbag strip 6. The fixing layer 62 is made of strong double-sided adhesive and has a thickness of 0.5 mm to 1 mm.

[0035] Specifically, during use, pressing the airbag strip 6 fixes the inner wall of the airbag strip 6 to the fixing layer 62. By compressing the volume of the airbag strip 6, the gas inside the airbag strip 6 is forced into the elastic airbag 4 through the air hole 61. This changes the gas volume inside the elastic airbag 4, causing the elastic airbag 4 to expand and the elastic opening 5 to shrink. This allows the elastic opening 5 to fit more tightly around the patient's enterostomy, thus seamlessly wrapping the enterostomy and greatly improving the sealing effect of the ostomy bag base, preventing excrement from leaking out from the gaps. Furthermore, by gradually compressing the volume of the airbag strip 6, the expansion size of the elastic airbag 4 can be controlled. The more the airbag strip 6 is compressed, the larger the elastic airbag 4 expands and the smaller the elastic opening 5 shrinks, which helps to improve the applicability of the ostomy bag base. In addition, the strong double-sided adhesive can bond the inner walls of both sides of the airbag strip 6 together.

[0036] The aforementioned elastic airbag 4 and airbag strip 6 are both made of rubber, and their wall thickness is 1 mm to 2 mm.

[0037] Specifically, by using rubber material, which has good elasticity, flexibility and sealing properties, it can ensure that the elastic port 5 fits tightly around the enterostomy, which helps to improve the sealing effect.

[0038] The aforementioned bonding area includes an adhesive layer 3 disposed on the surface of the substrate 1, on which release paper 31 is bonded. The adhesive layer 3 is made of water-based adhesive, and the thickness of the water-based adhesive is 0.3 mm to 1 mm. The size of the release paper 31 is larger than the size of the adhesive layer 3 so that the release paper 31 can be peeled off from the adhesive layer 3.

[0039] Specifically, the adhesive layer 3 allows the substrate 1 to be bonded to the patient's skin. The release paper 31 protects the adhesive layer 3 before use. The hydrocolloid forms a soft gel-like barrier that protects the wound from external contamination and friction damage. It also provides softness and cushioning, which helps reduce irritation to the wound during dressing changes and reduces patient discomfort and pain.

[0040] This utility model provides a stoma bag base plate suitable for ostomy bag assembly and installation, and also suitable for colonoscopy procedures; for example, if a patient has already undergone ostomy, the doctor can consider using the stoma bag with the above structure when performing a colonoscopy.

[0041] During the use of this stoma bag base plate, medical staff first clean and disinfect the skin at the patient's stoma site, and then measure the size of the patient's stoma. When the size of the stoma is larger than the diameter of the elastic port 5, the elastic port 5 on the elastic airbag 4 can be directly placed on the stoma. Through the elasticity of the elastic airbag 4, the elastic port 5 is made to fit tightly around the stoma. Then, the base plate 1 is evenly bonded to the patient's skin through the adhesive layer 3, thereby achieving a seal on the stoma.

[0042] In addition, when the size of the enterostomy is smaller than the diameter of the elastic port 5, by pressing the airbag strip 6, the inner wall of the airbag strip 6 is fixed by the fixing layer 62. By compressing the volume of the airbag strip 6, the gas inside the airbag strip 6 can be squeezed into the elastic airbag 4 through the air hole 61. This can change the gas volume inside the elastic airbag 4, causing the elastic airbag 4 to expand and the diameter of the elastic port 5 to shrink until the diameter of the elastic port 5 is slightly smaller than the size of the enterostomy.

[0043] Then, the elastic opening 5 on the elastic airbag 4 is put onto the enterostomy. Through the elasticity of the elastic airbag 4 itself, the elastic opening 5 is tightly fitted around the patient's enterostomy, thereby seamlessly wrapping the enterostomy and greatly improving the sealing effect of the ostomy bag base plate, preventing excrement from leaking out from the gaps. Finally, the substrate 1 is evenly bonded to the patient's skin through the adhesive layer 3.

[0044] On the other hand, by gradually compressing the volume of the airbag strip 6, the expansion size of the elastic airbag 4 can also be controlled. The more the airbag strip 6 is compressed, the larger the elastic airbag 4 expands and the smaller the diameter of the elastic opening 5 shrinks. By adjusting the size of the elastic opening 5, the applicability of the ostomy bag base plate can be improved.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
