Description

Technical Field

[0001] This utility model relates to the field of dressing technology, and more specifically, to a sacrococcygeal decompression dressing. Background Technology

[0002] Currently, patients who are bedridden for extended periods or undergo surgery lasting more than 4 hours lack protective measures. Bedridden patients generally rely on caregivers to constantly turn them over and massage them to prevent bedsores. However, even with these measures, bedsores are still very likely to occur. Statistics show that the rate of bedsores among long-term bedridden patients with excellent care is approximately 10%-25%, while the rate among normally bedridden patients is 20%-50%. Patients undergoing prolonged surgery are also highly susceptible to injury in the sacrum and coccyx area due to the hardness of the operating table.

[0003] However, because the sacrum and coccyx of the human body have irregular surfaces, general products cannot provide specialized stress relief care, and they cannot be applied directly to the skin. With the slightest movement, stress relief or care products are easily displaced, thus failing to provide effective care.

[0004] Therefore, a sacrococcygeal decompression dressing that can fit well into the sacrococcygeal region, provide good decompression, and is less prone to displacement is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sacrococcygeal decompression dressing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sacrococcygeal decompression dressing, comprising a protective layer, a foam layer, an adhesive layer, and a release layer, wherein the foam layer is fixed to the bottom of the protective layer, the top surface of the adhesive layer is bonded to the foam layer, and the bottom surface of the adhesive layer is bonded to the release layer.

[0007] Preferably, the protective layer is a non-woven fabric, polyurethane film, polyethylene film, polypropylene film, or polyethylene terephthalate film, and the thickness of the protective layer is 10μm-100μm.

[0008] Preferably, the foam layer is a polyurethane foam material with a thickness of 2-5 mm and a pore size of 10 μm-500 μm.

[0009] Preferably, the adhesive layer is used to adhere to the skin, and its material is hot melt pressure-sensitive adhesive, polyacrylate pressure-sensitive adhesive, polyurethane pressure-sensitive adhesive or silicone gel, with a basis weight of 10g / ㎡-100g / ㎡.

[0010] Preferably, the release layer is made of glassine release paper, CCK release paper, PET film or PE film, with a basis weight of 40g / ㎡-120g / ㎡.

[0011] Preferably, it further includes an adhesive portion and a pressure-reducing portion, wherein the pressure-reducing portion is a groove formed on the adhesive portion.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] (1) The special cutting shape ensures a perfect fit between the pressure relief patch and the sacral and coccygeal area;

[0014] (2) The use of silicone gel makes the pressure relief patch re-adhesive, reusable, economical and hygienic;

[0015] (3) Polyurethane foam dressings have good biocompatibility, avoiding skin allergies caused by prolonged use;

[0016] (4) Foam dressings can absorb sweat from the contact area, keep the air inside the mask dry, and improve comfort. Attached Figure Description

[0022] 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.

[0023] As attached Figure 1 The sacrococcygeal decompression dressing shown includes a protective layer 1, a foam layer 2, an adhesive layer 3, and a release layer 4. The foam layer 2 is fixed to the bottom of the protective layer 1, the top surface of the adhesive layer 3 is bonded to the foam layer 2, and the bottom surface of the adhesive layer 3 is bonded to the release layer 4.

[0024] The protective layer 1 is made of non-woven fabric, polyurethane film, polyethylene film, polypropylene film or polyethylene terephthalate film, and the thickness of the protective layer 1 is 10μm-100μm.

[0025] The foam layer 2 is a polyurethane foam material with a thickness of 2-5 mm and a pore size of 10 μm-500 μm.

[0026] The adhesive layer 3 is used to adhere to the skin, and its material is hot melt pressure-sensitive adhesive, polyacrylate pressure-sensitive adhesive, polyurethane pressure-sensitive adhesive or silicone gel, with a weight per square meter of 10g / ㎡-100g / ㎡.

[0027] The release layer 4 is made of glassine release paper, CCK release paper, PET film or PE film, and its basis weight is 40g / ㎡-120g / ㎡.

[0028] In practice, protective layer 1 has antibacterial and waterproof properties as well as a certain degree of water vapor permeability, allowing sweat to be normally discharged from the skin at the application site, preventing maceration or moisture accumulation. Adhesive layer 2 has good softness and can completely fit the coccyx. Protective layer 3 can be non-woven fabric or film material such as polyurethane film (PU), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. Foam layer 3 is made of foam material to relieve local pressure between the coccyx and the bed, preventing skin injury, and at the same time, it can absorb sweat at the application site, keeping the air inside the coccyx and the dressing dry, improving user comfort. Release layer 4 is used to protect adhesive layer 3 and prevent contamination from affecting use. When using, peel off release layer 4, apply the pressure-relieving dressing to the coccyx, and adjust the position or select the appropriate size according to the size of the coccyx.

[0029] It also includes an adhesive portion 5 and a pressure-reducing portion 6, wherein the pressure-reducing portion 6 is a groove formed on the adhesive portion 5.

[0030] In practice, by cutting the dressing into a pressure-relieving patch, a portion of the release layer 4 and adhesive layer 3 are cut out from the pressure-relieving patch, thereby creating a pressure-relieving part 6 with a groove structure in the adhesive part 5. The release layer 4 on the adhesive part 5 is then peeled off, and the pressure-relieving part 6 is aligned with the coccyx, so that the adhesive part 5 is adhered to the skin around the coccyx, and the pressure-relieving part 6 is fitted onto the coccyx, thus preventing the dressing from exerting adhesion pressure on the coccyx.

[0031] Example 1

[0032] like Figure 2 As shown, the pressure-reducing patch formed by cutting the sacrococcygeal pressure-reducing dressing provided in this embodiment 1 has a coccyx-shaped structure for the adhesive part 5 and the pressure-reducing part 6.

[0033] Example 2

[0034] like Figure 3As shown, the pressure-relieving patch formed by cutting the sacrococcygeal pressure-relieving dressing provided in this embodiment 2 has a heart-shaped structure for the adhesive part 5 and the pressure-relieving part 6.

[0035] Example 3

[0036] like Figure 4 As shown, the pressure-relieving patch formed by cutting the sacral and coccygeal pressure-relieving dressing provided in this embodiment 3 has an adhesive part 5 with a butterfly-shaped structure and a pressure-relieving part 6 with a Y-shaped structure.

[0037] These embodiments one to three provide pressure relief patches with different structures, which can match the coccyx shape of most people. In order to improve the matching and thus achieve a better pressure relief effect by using pressure relief patches with different structures according to the different coccyx shapes of patients.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
