Description

Technical Field

[0001] This utility model relates to the field of perianal pressure ulcer dressing technology, and in particular to a perianal pressure ulcer dressing that is easy to replace. Background Technology

[0002] Anal pressure ulcer dressings are medical dressings used to prevent and treat pressure injuries (i.e., pressure ulcers) in the perianal area, primarily for patients who are bedridden for extended periods, have limited mobility, or experience severe localized skin pressure. These dressings are typically made of soft, breathable, and skin-friendly materials to reduce local friction and pressure, prevent ischemic necrosis of tissue, and promote wound healing. Their surface may have a waterproof and breathable layer to prevent external contamination, while the interior contains highly absorbent materials to effectively manage exudate and maintain a moist wound environment. Some anal pressure ulcer dressings also have antibacterial properties to reduce the risk of infection and improve patient comfort and care outcomes.

[0003] Existing perianal pressure ulcer dressings mostly adopt a single-piece design. The method of use involves directly applying the dressing, with an adhesive layer on one side, to the perianal area of ​​patients with perianal abscesses. While this design is convenient, the edges of the dressing are easily contaminated during defecation, forcing caregivers to completely remove the entire dressing before replacing it with a new one. This replacement method not only causes significant discomfort for the patient but also increases pain and the risk of infection during the procedure. Therefore, there is an urgent need to develop a new type of perianal pressure ulcer dressing that allows for localized replacement of the contaminated area without requiring complete removal, thereby improving the patient experience and increasing care efficiency.

[0004] Based on this, we propose an easily replaceable perianal pressure ulcer dressing to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide an easily replaceable perianal pressure ulcer dressing, which can solve the problems of traditional single-piece perianal pressure ulcer dressings being easily contaminated at the edges during defecation, requiring complete removal and replacement, which leads to patient discomfort, increased pain, and increased risk of infection.

[0007] To solve the above-mentioned technical problems, this utility model provides an easily replaceable perianal pressure ulcer dressing, which adopts the following technical solution: it includes a base film, a pressure ulcer adsorption film is provided on the top of the base film, and a U-shaped groove for anal leakage is respectively opened on one side of the base film and the pressure ulcer adsorption film. The pressure ulcer adsorption film includes an adhesive substrate, and a pressure ulcer patch is provided at the bottom of the adhesive substrate. The retention base film has a heart-shaped hollow groove in the middle, and a first adhesive layer is also provided on the side of the retention base film near the heart-shaped hollow groove.

[0008] Optionally, the heart-shaped perforated groove matches the structure of the pressure ulcer patch, and the heart-shaped perforated groove and the pressure ulcer patch have a transitional fit.

[0009] Optionally, the adhesive substrate has a retaining groove formed around the perimeter of the side near the pressure ulcer patch, and a second adhesive layer is provided on the outer surface of the retaining groove. The second adhesive layer matches the structure of the first adhesive layer, and the second adhesive layer and the first adhesive layer are adhesively bonded together.

[0010] Optionally, the bonding substrate includes a waterproof inner layer, an adsorbent outer layer is provided on the outside of the waterproof inner layer, and an adhesive paper layer is provided between the adsorbent outer layer and the waterproof inner layer.

[0011] Optionally, both the waterproof inner layer and the retention base film are made of high molecular polymer materials, specifically bio-silicone, and the adsorbent outer layer is composed of high molecular water-absorbing resin and fluff pulp material.

[0012] Optionally, a wound waterproofing patch 13 is also provided around the perimeter of the base film 1 on the side away from the first adhesive layer 7.

[0013] In summary, this utility model has at least one of the following beneficial effects: 1. The perianal pressure ulcer patch designed in this solution allows for easy adhesion of the base film to the outer side of the perianal area of ​​patients with perianal abscesses through the first adhesive layer on both sides of the base film, achieving a stable adhesion effect. At the same time, the heart-shaped hollow groove in the center of the base film exposes the perianal abscess area of ​​the patient, facilitating targeted pressure ulcer care. Through the adhesive base of the pressure ulcer absorbent film, the retaining groove on one side of the pressure ulcer patch, and the second adhesive layer on its outer surface, the pressure ulcer absorbent film can be adhered and fixed to the outer side of the base film, achieving a transition fit between the pressure ulcer patch and the heart-shaped hollow groove. This allows the pressure ulcer patch to be embedded in the inner wall of the heart-shaped hollow groove, providing effective pressure ulcer care for the exposed perianal abscess area.

[0014] 2. The perianal pressure ulcer patch designed in this scheme improves the flexibility and waterproofness of the base film by selecting materials and structural design for the waterproof inner layer and the absorbent outer layer. Simultaneously, the high absorbency of the superabsorbent polymer resin and fluff pulp material in the absorbent outer layer effectively absorbs dirt, keeping the outer side of the pressure ulcer patch clean and dry. When the patient defecates, the patch quickly absorbs dirt from the outside, and the adhesive layer allows the absorbent outer layer to be easily peeled off from the waterproof inner layer, maintaining the cleanliness of the outer side of the patch. When the patch becomes contaminated with external dirt, the adhesive structure between the second and first adhesive layers allows for easy removal of the entire absorbent membrane adhering to the outer side of the base film, enabling localized replacement of only the contaminated portion. This effectively reduces discomfort and pain during the replacement process, achieving continuous, comfortable, and efficient pressure ulcer care. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Refer to Figures 1 to 5 This utility model provides an embodiment of a replaceable perianal pressure ulcer dressing, comprising a base film 1, a pressure ulcer absorbent film 2 at the top of the base film 1, and U-shaped slots 3 for anal leakage on one side of both the base film 1 and the absorbent film 2. The absorbent film 2 includes an adhesive substrate 4, a pressure ulcer patch 5 at the bottom of the adhesive substrate 4, a heart-shaped perforated groove 6 in the middle of the base film 1, and a first adhesive layer 7 on the side of the base film 1 near the heart-shaped perforated groove 6. The base film 1 is covered by the first adhesive layers on both sides. 7. It is convenient to attach the indwelling base membrane 1 to the outside of the perianal area of ​​the patient with perianal abscess. The heart-shaped hollow groove 6 opened in the middle of the indwelling base membrane 1 can expose the perianal abscess area of ​​the patient. The heart-shaped hollow groove 6 matches the structure of the pressure ulcer patch 5. The heart-shaped hollow groove 6 and the pressure ulcer patch 5 are in a transition fit. Through the structural design of the transition fit between the pressure ulcer patch 5 and the heart-shaped hollow groove 6, the pressure ulcer patch 5 can be embedded in the inner wall of the heart-shaped hollow groove 6. The embedded pressure ulcer patch 5 can provide pressure ulcer care for the perianal abscess area exposed inside the heart-shaped hollow groove 6.

[0020] The bonding substrate 4 has a groove 8 formed around the perimeter of the side near the pressure ulcer patch 5. A second adhesive layer 9 is provided on the outer surface of the groove 8. The second adhesive layer 9 is structurally matched with the first adhesive layer 7, and the second adhesive layer 9 and the first adhesive layer 7 are adhesively fitted together. Through the adhesive fit between the second adhesive layer 9 and the first adhesive layer 7, the pressure ulcer patch 5, which is embedded in the heart-shaped hollow groove 6, can be adhered and fixed to the outside of the placement base film 1. The bonding substrate 4 includes a waterproof inner layer 10. An absorbent outer layer 11 is provided on the outside of the waterproof inner layer 10. An adhesive paper layer 12 is also provided between the absorbent outer layer 11 and the waterproof inner layer 10. The absorbent outer layer 11 can be adhered by the adhesive paper layer 12 provided between the absorbent outer layer 11 and the waterproof inner layer 10. The outer layer 11 is fixed to the outside of the waterproof inner layer 10, and the waterproof inner layer 10 can be peeled off according to the usage. Both the waterproof inner layer 10 and the retention base film 1 are made of high molecular polymer material, specifically bio-silicone. The waterproof inner layer 10 and the retention base film 1 are both made of bio-silicone, which can improve the waterproofness of the perianal pressure ulcer patch itself, as well as the flexibility of the patch on the outside of the patient's perianal area. The outer layer 11 is composed of superabsorbent polymer and fluff pulp material. The outer layer 11 made of this material has high water absorption capacity. When the patient with perianal abscess defecates, the outer layer 11 set on the outermost layer of the adhesive base 4 can effectively absorb dirt.

[0021] A waterproof wound dressing 13 is also provided around the periphery of the base film 1 on the side away from the first adhesive layer 7. This waterproof wound dressing 13 is a commonly used type in the prior art, usually made of medical-grade polyurethane film, polyethylene, polypropylene composite material and acrylic adhesive. These materials have excellent waterproofness, breathability and flexibility. They can effectively block external moisture, liquid and bacteria, while allowing excess moisture to drain from the wound, maintaining a suitable moist environment, which is conducive to wound healing. When used to apply perianal pressure ulcer dressings, the waterproof wound dressing 13 can prevent urine, sweat or water from washing from seeping into the wound, thereby reducing the risk of infection. The waterproof wound dressing 13 can fit well into the complex curvature of the perianal area, ensuring long-term stable fixation. At the same time, the waterproof wound dressing 13 uses medical-grade adhesive, which is less irritating to the skin, easy to tear off, and less likely to cause secondary damage. The breathable design of the waterproof wound dressing 13 helps to maintain the local environment dryness, reduce skin friction and the possibility of further deterioration of pressure ulcers.

[0022] Working principle: The perianal pressure ulcer dressing designed in this scheme mainly consists of two parts: a base film 1 and a pressure ulcer absorbent film 2. The base film 1 is easily adhered to the outside of the perianal area of ​​the patient with perianal abscess through the first adhesive layers 7 set on both sides and around the periphery. The heart-shaped hollow groove 6 in the middle of the base film 1 exposes the perianal abscess area of ​​the patient. The pressure ulcer absorbent film 2 in this scheme mainly consists of an adhesive substrate 4 and a pressure ulcer patch 5. The adhesive substrate 4 and the pressure ulcer patch 5 form a barrier around one side and around the periphery. The groove 8 has a second adhesive layer 9 on its outer surface. Since the second adhesive layer 9 and the first adhesive layer 7 are structurally matched and are adhesively fitted, the pressure ulcer absorbent membrane 2 can be adhered and fixed to the outside of the placement base membrane 1. The pressure ulcer absorbent membrane 2 can be embedded in the inner wall of the heart-shaped hollow groove 6 through the structural design of the transition fit between the pressure ulcer patch 5 and the heart-shaped hollow groove 6. The embedded pressure ulcer patch 5 can provide pressure ulcer care for the exposed perianal abscess inside the heart-shaped hollow groove 6.

[0023] The bonding substrate 4 in this design mainly consists of a waterproof inner layer 10, an absorbent outer layer 11, and an adhesive layer 12. The waterproof inner layer 10 and the retention base film 1 are both made of bio-silicone, which enhances the waterproofness of the perianal pressure ulcer patch itself and its flexibility when applied to the patient's perianal area. This also improves the waterproofness of the retention base film 1 and the pressure ulcer patch 5. The absorbent outer layer 11 is composed of superabsorbent polymer and fluff pulp material. This material gives the absorbent outer layer 11 high water absorption capacity. When a patient with perianal abscess defecates, the absorbent outer layer 11 is placed at the outermost part of the bonding substrate 4... The outer absorbent outer layer 11 can effectively absorb dirt. In conjunction with the adhesive paper layer 12 between the waterproof inner layer 10, the absorbent outer layer 11 with dirt adsorbed on the outside can be easily peeled off from the outside of the waterproof inner layer 10, so that the outside of the pressure ulcer patch 5 for perianal abscess pressure ulcer care remains clean and dry. When the pressure ulcer patch 5 is contaminated by dirt adhering to the outside of the absorbent outer layer 11, the pressure ulcer absorbent membrane 2 can also be peeled off from the outside of the base membrane 1 through the structural design of the adhesive cooperation between the second adhesive layer 9 and the first adhesive layer 7.
