[0020] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0021] like Figure 1 , 2 , 3 and 4 are specific embodiments of the multi-layer dressing for circumcision wounds of the utility model. The dressing of this embodiment includes a base material layer 1, a core layer 2 made of a water-absorbing material and a perforated adhesive layer 3. The base material layer 1 is arranged on the outer side of the core layer 2, and the adhesive layer 3 is arranged on the inner side of the core layer 2 for bonding the wound.
[0022] When the utility model is in use, the core layer 2 is pasted corresponding to the annular wound position, the adhesive layer 3 is adhered to the wound by its viscosity, and the tail end of the dressing is adhered to the outside of the base material layer 1, which improves the limiting effect of the core layer 2 and prevents the dressing from falling off. The outside is covered with an elastic bandage and gently pressurized to achieve a good hemostatic effect. The holes on the adhesive layer 3 allow the bleeding and exudate at the wound to be absorbed by the core layer 2, thereby keeping the wound clean, promoting healing, and preventing wound adhesion.
[0023] As an improved specific implementation manner, the core layer 2 is arranged in the middle of the dressing, and the outer side surface of the adhesive layer 3 is bonded to the base material layer 1 and the core layer 2 .
[0024] During the specific implementation, the core layer 2 is located in the middle and corresponds to the wound to absorb the bleeding and exudate at the wound. The periphery is sealed by the adhesion of the adhesive layer 3 to prevent moisture evaporation and avoid the wound from drying and adhesion. It is convenient for dressing changes, keeps the wound moist, promotes moist healing of the wound, and also helps prevent urine from penetrating from the periphery of the core layer 2 and wetting and contaminating the wound.
[0025] As an improved specific implementation, the dressing has a long strip structure, the core layer 2 is arranged along the length direction of the dressing and located in the middle, and along the width direction of the dressing, the edges of both sides of the core layer 2 are on the inner side of the adhesive layer 3.
[0026] like Figure 3 , 4 As shown, the strip-shaped dressing is wound around the wound after circumcision surgery. According to the shape characteristics of the penis, the strip-shaped dressing can be wound in various ways according to the different lengths of the annular wound of the penis to achieve a good dressing effect, thereby reducing the size design of the dressing, reducing the difficulty of dressing processing, and reducing processing costs. The width of the core layer 2 is narrower than the viscose layer 3. After the dressing is wrapped and bandaged, the side of the core layer 2 can be sealed by the adhesion of the viscose layers 3 on both sides, which prevents water evaporation and prevents the wound from drying and adhesion, making it easy to change the dressing, keep the wound moist, promote moist healing of the wound, and also help prevent urine from penetrating from the side of the core layer 2 and contaminating the wound.
[0027] As an improved specific implementation manner, a peelable release film layer 4 is further provided on the inner side of the adhesive layer 3 .
[0028] like Figure 1 , 2 As shown, the provision of the release film layer 4 allows the adhesive layer 3 on the inner side of the dressing to be well protected when the dressing is not in use, thereby avoiding damage and contamination, and also facilitating storage.
[0029] As an improved specific implementation manner, at least one long strip-shaped large hole 32 penetrating the adhesive layer 3 is provided on the adhesive layer 3 at a position corresponding to the outer core layer 2 .
[0030] like Figure 4As shown, at least one large hole 32 is located in the middle of the core layer 2, maintaining the largest direct contact area between the water-absorbing material and the foreskin wound, improving the water absorption effect of the wound, and the adhesive layer 3 around the large hole 32 is bonded to the wound to ensure the fixing effect of the dressing. As needed, a number of holes can be added around the large hole 32 to assist in the drainage of the liquid and improve the water absorption performance.
[0031] As an improved specific implementation manner, the holes on the adhesive layer 3 are a plurality of small holes 31 penetrating the adhesive layer 3 .
[0032] like Figure 1 , 3 As shown, a plurality of small holes 31 increase the adhesion area of the adhesive layer 3 to the wound surface and expand the range of the water absorption area while ensuring that the liquid can smoothly pass through to the core layer 2 to be absorbed, thereby achieving both reliable adhesion and fixation of the dressing on the wound and ensuring the water absorption effect.
[0033] As an improved specific implementation manner, the small holes 31 are evenly arranged on the adhesive layer 3 .
[0034] In specific implementation, the evenly arranged small holes 31 can make the wound adhesion and water absorption better, and each area can achieve a balanced water absorption effect, keeping the wound clean and promoting healing; the evenly arranged small holes 31 are more convenient for the processing and manufacturing of the adhesive layer 3.
[0035] As an improved specific implementation manner, the material of the core layer 2 contains alginate fibers.
[0036] In the specific implementation, the core layer 2 contains alginate fiber material, which has high hygroscopicity. When the core layer 2 containing alginate comes into contact with the wound exudate, it can form a soft and transparent gel, and then penetrate into the wound through the small holes 31, providing an ideal moist environment for wound healing, and playing a role in reducing infection, reducing inflammatory response, reducing local pain, helping to stop bleeding, and promoting wound healing.
[0037] As an improved specific implementation manner, the adhesive layer 3 is a perforated soft silicone colloid layer or a perforated silicone gel colloid layer.
[0038] In specific implementation, the soft polysilicone or silicone gel colloid layer has no irritation to human skin tissue, and can rely on its good material properties to gently adhere to the wound, so that the core layer 2 is well limited and covered and fixed in the wound area, playing a role in stably protecting the wound. In addition, the soft polysilicone or silicone gel colloid layer also has the property of being re-adhesive, which is convenient for repeated operation to adjust the dressing area when bandaging the wound, and the above-mentioned material has the advantage of not sticking to the wet wound, making it easy to separate from the wound when changing the dressing, effectively reducing the damage and pain caused when changing the dressing. The holes in the soft polysilicone colloid layer or silicone gel colloid layer serve to drain the wound exudate to the outer core layer 2, keeping the wound surface clean.
[0039] As an improved specific implementation manner, the substrate layer 1 is a film made of polyurethane.
[0040] In specific implementation, the film made of polyurethane has the functions of waterproof and breathable and preventing water evaporation, which can prevent the wound from being wetted and contaminated by urine, keep the wound surface moist, and promote moist healing of the wound. Its excellent wear resistance, tensile strength and elongation can better exert its performance when used in foreskin wound dressing, making the dressing more stable and durable.
[0041] As an improved specific implementation, the dressing includes a laying head end 01 and a laying tail end 02, the core layer 2 extends to the laying head end 01, there is a gap between the core layer 2 and the laying tail end 02, and an adhesive layer 3 is arranged in the gap for bonding and sealing the wound.
[0042] like Figure 2 , 3 As shown in Figure 4, when bandaging the wound, start from the laying head end 01, make the core layer 2 of the laying head end 01 directly contact the wound and form a ring when winding, so that all wounds are in a continuous water absorption area, ensuring the water absorption effect of the dressing, keeping the wound clean and promoting healing; leave a gap at the laying tail end 02 and no longer set the core layer 2, and use the adhesive layer 3 for bonding, so that the laying tail end 02 forms a seal on the wound, on the one hand, it plays a role in waterproofing, preventing liquid water from evaporating, and keeping the wound moist, on the other hand, it avoids the entry of dust and bacteria and prevents wound infection.
[0043] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
