Description

Technical Field

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

[0002] Ostomy bags generally consist of two parts: an ostomy base plate and a bag body. The bag body is attached to the base plate, and the side of the ostomy base plate facing away from the bag body has adhesive to be attached around the stoma. The patient's urine or feces can be collected in the bag body through the stoma, and then the bag body is processed.

[0003] After the stoma baseplate is manufactured, a release liner is usually attached to the adhesive side. This release liner is peeled off when the patient needs it, ensuring the adhesive side is in optimal adhesion. However, because existing release liner is usually a single piece designed to fit the adhesive side, attaching and adjusting the stoma baseplate after peeling off the release liner is very inconvenient. Furthermore, the adhesive side is easily touched by hand during this process, affecting its adhesion.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0005] The purpose of this utility model is to provide an ostomy base plate and an ostomy bag, so as to facilitate the attachment and adjustment of the ostomy base plate, and to prevent human hands from touching the adhesive surface.

[0006] The purpose of this utility model is achieved through the following technical solution: a stoma base plate, comprising:

[0007] The substrate has an adhesive surface that adheres to the skin;

[0008] Release paper is attached to the adhesive surface, and the release paper includes a first release paper and a second release paper that are independent of each other;

[0009] The first release paper covers at least the central area of ​​the adhesive surface, and the second release paper covers part or all of the edge area of ​​the adhesive surface. The first release paper and the second release paper can be peeled off from the adhesive surface one after the other.

[0010] Furthermore, the projections of the first release paper and the second release paper in the direction perpendicular to the adhesive surface do not coincide; or, the projections of the first release paper and the second release paper in the direction perpendicular to the adhesive surface have overlapping areas.

[0011] Furthermore, the second release paper is arranged in a ring at the edge region of the adhesive surface, and the second release paper is continuously distributed along the edge of the adhesive surface.

[0012] Furthermore, the second release paper is ring-shaped and disposed on the edge region of the adhesive surface, and the second release paper is discontinuously distributed along the edge of the adhesive surface.

[0013] Furthermore, the second release paper is cut with a cutting portion that extends from the outer edge of the first release paper to the inner edge of the second release paper.

[0014] Furthermore, the cutting portion is a slit and / or cut, and the number of cutting portions is at least two, so as to divide the second release paper into at least two independent release portions.

[0015] Furthermore, the cutting portion is a slit, and the first release paper covers the area of ​​the adhesive surface corresponding to the slit.

[0016] Furthermore, the outer edges of the first release paper and / or the second release paper are provided with tear-off portions.

[0017] Furthermore, the matrix comprises:

[0018] An adhesive layer having the adhesive surface;

[0019] A backing layer is laminated to the other side of the adhesive layer opposite to the adhesive surface;

[0020] An annular extension is formed between the outer edge of the adhesive layer and the outer edge of the backing layer to serve as the edge region of the substrate.

[0021] In addition, this utility model also provides an ostomy bag, including the aforementioned ostomy base plate.

[0022] Compared with the prior art, the present invention has the following advantages: By setting a first release paper and a second release paper attached to the adhesive surface, the first release paper covers at least the central area of ​​the adhesive surface, and the second release paper covers part or all of the edge area of ​​the adhesive surface. When the patient needs to have the stoma baseplate applied, the first release paper can be peeled off the substrate first, allowing the central area of ​​the adhesive surface to be attached around the stoma. The patient can adjust the position of the substrate by contacting the corresponding part of the substrate and the second release paper, ensuring precise alignment of the central area of ​​the substrate with the stoma position. This ensures the sealing and stability around the stoma, effectively avoids direct contact between human hands and the adhesive surface, prevents adhesive contamination, and is very easy to adjust. After the middle area of ​​the substrate is fixed, the second release paper can be peeled off the adhesive surface so that the edge area of ​​the adhesive surface can adhere to the human body. This avoids the edge area being fixed too early, which would make the middle area difficult to adjust. Fixing the middle area first can provide support for the edge area, ensuring a more secure overall adhesion and making it easier to adjust the edge area according to the skin condition. This allows the patient to better control the adhesion process and reduce operational errors. Attached Figure Description

Detailed Implementation

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0030] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0031] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] Please see Figures 1 to 4As shown, the stoma base plate corresponding to a preferred embodiment of the present invention includes: a base 100 having an adhesive surface 110 that adheres to the skin; and release paper attached to the adhesive surface 110, the release paper including a first release paper 200 and a second release paper 300 that are independent of each other; wherein, the first release paper 200 covers at least the central region of the adhesive surface 110, the second release paper 300 covers part or all of the edge region of the adhesive surface 110, and the first release paper 200 and the second release paper 300 can be peeled off from the adhesive surface 110 one after the other.

[0033] This invention utilizes a first release paper 200 and a second release paper 300 attached to an adhesive surface 110. The first release paper 200 covers at least the central region of the adhesive surface 110, and the second release paper 300 covers part or all of the edge region of the adhesive surface 110. When the patient needs to have the stoma baseplate applied, the first release paper 200 can be peeled off the substrate 100 to attach the central region of the adhesive surface 110 around the stoma. The patient can adjust the position of the substrate 100 by contacting the corresponding parts of the substrate 100 and the second release paper 300, ensuring precise alignment of the central region of the substrate 100 with the stoma location. Alignment ensures a tight seal and stability around the stoma, effectively preventing direct contact between the adhesive surface 110 and the patient's hands, thus preventing adhesive contamination and facilitating easy adjustment. Once the central area of ​​the substrate 100 is fixed, the second release paper 300 can be peeled off the adhesive surface 110 to allow the edge area of ​​the adhesive surface 110 to adhere to the body. This prevents the edge area from being fixed too early, which could make the central area difficult to adjust. Fixing the central area first provides support for the edge area, ensuring a more secure overall adhesion and facilitating adjustments to the edge area based on the skin condition. This allows the patient to better control the adhesion process and reduces operational errors.

[0034] Furthermore, the outer contour of the substrate 100 is elliptical to better fit the human body and adapt to different stoma locations. A stoma hole 120 is provided in the central region of the substrate 100. A first release paper 200 covers the central region of the adhesive surface 110, and the first release paper 200 has openings corresponding to the stoma hole 120. The side of the first release paper 200 facing away from the adhesive surface 110 has several cutting indicator lines 210 with the same axis as the stoma hole 120, so as to flexibly cut stoma holes 120 of different diameters according to the actual stoma size. A second release paper 300 is arranged around the edge region of the adhesive surface 110. The outer contours of the first release paper 200 and the second release paper 300 are preferably elliptical with the same axis as the substrate 100. A tear-off portion 220 is provided on the outer edge of the first release paper 200 and / or the second release paper 300. The tear-off portion 220 may extend in a direction parallel to the adhesive surface 110 and protrude beyond the edge of the substrate 100 to facilitate the patient tearing off the release paper. Preferably, the tear-off portion 220 is arranged off-axis from the major and minor axes of the substrate 100 to make it more ergonomic.

[0035] In this embodiment, the substrate 100 includes an adhesive layer 130 and a backing layer 140. The adhesive layer 130 has an adhesive surface 110, and the backing layer 140 is laminated to the other side of the adhesive layer 130 opposite to the adhesive surface 110. An annular extension 150 is formed between the outer edge of the adhesive layer 130 and the outer edge of the backing layer 140 to serve as the edge region of the adhesive surface 110, while the portion of the adhesive surface 110 corresponding to the backing layer 140 serves as the central region of the adhesive surface 110. By providing the extension portion 150, when the stoma baseplate is attached to the human body, the extension portion 150 can improve the tightness of the connection between the stoma baseplate and the human body, extend the service life of the stoma baseplate, and prevent the stoma baseplate from falling off the human body after a short period of attachment. In addition, since the extension portion 150 is thinner, by attaching the second release paper 300 to the extension portion 150, the extension portion 150 is less likely to wrinkle when the first release paper 200 is peeled off, thus improving the user experience.

[0036] Furthermore, in one embodiment, the projections of the first release paper 200 and the second release paper 300 in the direction perpendicular to the adhesive surface 110 have overlapping areas, that is, at least a portion of the second release paper 300 is located between the first release paper 200 and the adhesive surface 110. The first release paper 200 may partially or completely cover the second release paper 300, which is not limited herein. With the above structure, the portion of the first release paper 200 covering the second release paper 300 can form a tear-off structure that is separated from the adhesive surface 110. The patient can easily tear off the first release paper 200 through the tear-off structure. In this case, the first release paper 200 does not need to be provided with a tear-off portion 220, thereby simplifying the overall structure.

[0037] Preferably, in this embodiment, the projections of the first release paper 200 and the second release paper 300 in the direction perpendicular to the adhesive surface 110 do not overlap; that is, the first release paper 200 covers a portion of the adhesive surface 110, and the second release paper 300 covers the remaining portion of the adhesive surface 110. With this structure, the first release paper 200 and the second release paper 300 do not interfere with each other, making tearing easier. During production, the first release paper 200 and the second release paper 300 can be cut from single sheets of release paper adapted to the adhesive surface 110, simplifying the process, increasing production efficiency, saving release paper usage, and effectively reducing costs.

[0038] Furthermore, the second release paper 300 can be continuously distributed along the edge of the adhesive surface 110, that is, it is a single ring-shaped release paper, thereby simplifying the processing technology. However, using a single piece of second release paper 300 makes tearing inconvenient. As a preferred embodiment, the second release paper 300 is discontinuously distributed along the edge of the adhesive surface 110, that is, the second release paper 300 is divided into several independent release portions 310, which facilitates tearing.

[0039] Specifically, the second release paper 300 is cut with a cutting portion 320, which extends from the outer edge of the second release paper 300 to the inner edge of the second release paper 300. There are at least two cutting portions 320 to divide the second release paper 300 into at least two independent release portions 310. Preferably, in this embodiment, there are two cutting portions 320, which are arranged opposite to each other, thereby dividing the second release paper 300 into two equal release portions 310, simplifying the process and making it easier to tear off the release portions 310.

[0040] Furthermore, the cutting portion 320 can be a slit and / or an incision. However, when a slit is used, the separated release portions 310 are adjacent to each other, and their circumferential dimension on the substrate 100 is relatively long, making it inconvenient to tear off the release portions 310. Preferably, in this embodiment, the cutting portions 320 are preferably all in the form of incisions, and the first release paper 200 extends with a filling portion 230 covering the area of ​​the adhesive surface 110 corresponding to the incision.

[0041] After the first release paper 200 is peeled off, the incision allows the separated release portions 310 to be spaced apart by a certain distance. The patient can directly peel off the release portion 310 at the incision, eliminating the need for a tear-off portion 220 on the second release paper 300 and simplifying its structure. Preferably, the outer perimeter of the release portion 310 can be slightly larger than the outer perimeter of the substrate 100 to further improve the ease of peeling off the release portion 310. Furthermore, when the projections of the first release paper 200 and the second release paper 300 in the direction perpendicular to the adhesive surface 110 do not coincide, the incision can also avoid the first release paper 200, allowing the first release paper 200 to extend through the incision to form the tear-off portion 220. Preferably, the first release paper 200 forms the tear-off portion 220 only at one incision, and the opening size of this incision is smaller than the opening size of the other incision, facilitating the peeling off of the first release paper 200.

[0042] In addition, this utility model also provides an ostomy bag, including the aforementioned ostomy base plate and a bag body detachably connected to the ostomy base plate.

[0043] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
