Abstract
Description
Technical Field
[0001] The utility model belongs to the field of scar repair, and specifically relates to a repair mask for preventing and treating scar hyperplasia. Background Art
[0002] Pressure therapy is the most specialized rehabilitation treatment measure in burn rehabilitation. Pressure therapy is one of the most effective non-surgical methods for preventing and treating hypertrophic scars, as confirmed by evidence-based medicine. Early and continuous use of pressure therapy can reduce scar formation and promote scar maturation. Although the mechanism of action of pressure therapy in treating scars needs to be further elucidated, it is currently listed as one of the most common and effective methods for preventing and treating hypertrophic scars because of its safety, simplicity, low cost, definite efficacy, low recurrence rate, and suitability for patients who are not (willing to) undergo surgery.
[0003] The method of preventing and treating scar hyperplasia by continuously compressing the wound healing area with elastic fabric is called pressure therapy. Commonly used pressure treatment methods include sponge pressure fixation pads, plastic orthotics, elastic bandage pressure, elastic clothing (sleeves) pressure, silicone film application pressure and other methods.
[0004] At present, pressure therapy has become the standard and preferred method for treating burn scars. With the continuous improvement of manufacturing processes and materials, pressure therapy has also been greatly developed, from the initial simple application of elastic bandages, elastic sleeves or elastic clothing to the current multiple methods. However, the original treatment methods cannot suppress and solve the problem of scar hyperplasia. The product of the utility model realizes the perfect combination of silicone gel and pressure therapy. The prepared repair mask realizes the precise compression treatment of scars, and at the same time greatly reduces the patient's treatment costs, reduces the chance of surgery, and improves the patient's quality of life. Utility Model Content
[0005] The utility model aims to provide a repair mask for preventing and treating scar hyperplasia in view of the problems existing in the prior art.
[0006] The purpose of the utility model can be achieved by the following scheme:
[0007] The utility model provides a repairing mask for preventing and treating scar hyperplasia, comprising a mask body fitted on the human face and a fixing belt detachably connected to the mask body.
[0008] As an embodiment of the utility model, the mask body includes an inner gel layer and an outer pressure layer, the gel layer is attached to the pressure layer and contacts the skin. The pressure layer can fix the gel layer so that the gel is evenly and continuously attached to the skin surface.
[0009] As an embodiment of the utility model, the mask body is provided with openings corresponding to the eyes, nose and mouth of the human face, and the shapes of the openings are respectively consistent with the outer contours of the eyes, nose and mouth.
[0010] As an embodiment of the present invention, the thickness of the gel layer is 200-1000 μm, and the thickness of the pressure layer is 2500-4000 μm.
[0011] As an embodiment of the utility model, the edges of both sides of the mask body are provided with a plurality of groups of symmetrically distributed holes for the fixing belt to pass through the mask body and be detachably connected thereto. The holes are 2-4 groups, preferably 2 groups, arranged vertically near the corresponding positions of the mask and the ears of the human face, so that the fixing belt can pass around the human head and then fix the mask.
[0012] As an embodiment of the utility model, the fixing straps include a fleece Leica fabric layer, a nylon Leica fabric layer, and a sponge layer in sequence; two fixing straps form a group, and both ends of the first fixing strap are provided with Velcro hook surfaces, and one end of the second fixing strap is provided with a Velcro hook surface. One end of the two fixing straps provided with Velcro hook surfaces passes through a group of symmetrically distributed holes provided on the mask body, and the Velcro hook surfaces are adhered to the velvet surface on the fleece Leica fabric layer, and there is no need to provide a Velcro fur surface separately, so as to connect the fixing straps to the mask body. The other ends of the two fixing straps are adhered to the velvet surface on the fleece Leica fabric layer on the second fleece Leica fabric layer through the Velcro hook surface on the first strap, so as to fix the mask on the patient's face. When the patient wears it, the Velcro hook surface can be used to achieve bonding at any position with the velvet surface on the fleece Leica fabric layer on the entire face, so as to achieve arbitrary adjustment of the tightness of the mask.
[0013] As an embodiment of the utility model, the silicone gel layer is provided with fiber filaments near the edge of the mask, and the long diameter of the fiber filaments is 1 / 3-1 / 2 of the thickness of the gel layer. The edge of the mask includes the edge of the entire mask and the edge of the internal opening, and the distance between the fiber filaments and the edge of the mask is 0.3-1cm. The function of the fiber filaments is to enhance the strength of the edge of the silicone gel layer. The fiber filaments used have good strength and elastic recovery ability, and are preferably polyester fibers. Since the gel is relatively soft, when it is squeezed during daily use, especially when the mask is subsequently fine-tuned and softened, the setting of the fiber filaments helps to shape the boundaries of the gel. When the extrusion pressure is large, it will not be squeezed out of the pressure layer range, and it can also prevent the gel from being used for a long time and expanding and deforming under the action of sweat. The fiber filament material is relatively soft and does not affect normal use.
[0014] As an embodiment of the utility model, the mask body is integrally formed according to the curved surface of the human face, and the silicone gel material used in the gel layer is SILPURAN 2112, which is composed of polydimethylsiloxane containing functional groups and a cross-linking aid. The material used in the pressure layer is a softenable material, including PETG (polyethylene terephthalate-1,4-cyclohexanedimethanol ester) or a low-temperature thermoplastic plate; preferably PETG.
[0015] The mask body is prepared by the following method: making a mold of the same proportion as the human face; heating and softening a softenable material, covering it on the mold, and preparing a pressure layer through a vacuum forming process. After the preparation is completed, the opening parts (eyes, nostrils, mouth, etc.) and excess parts are removed; arranging fiber filaments on the outer edge of the pressure layer and the edge of the inner opening part, and then evenly spraying the silicone gel material on the inner side of the cooled pressure layer, and forming a gel layer after curing to obtain the mask body.
[0016] The mold includes a medical plaster mold and an EPP foam mold. The mold used can be partially removed later to adapt to the changes in scar hyperplasia. When the pressure layer is PETG, the heating and softening temperature is 100-120°C; the pressure layer is a low-temperature thermoplastic plate (HWP-3200), and the heating and softening temperature is 60-70°C. The pressure layer is shaped with the help of the mold, and the pressure layer is obtained by cooling and shaping after vacuum forming. After preparation, the opening parts (eyes, nostrils, mouth, etc.) and excess parts are removed. After removal, it is also cleaned and disinfected.
[0017] The repair mask of the utility model can also be fine-tuned in the later stage of treatment, and the steps are as follows: compare the mold and the scar hyperplasia part, remove the corresponding part of the mold and the scar hyperplasia change part; heat and soften the silicone gel film at the position corresponding to the mold removal part, cover it on the mold, squeeze the corresponding mold removal part to fit the mold, and cool and solidify. The pressure layer is PETG, and the heating and softening temperature is 100-120℃; the pressure layer is a low-temperature thermoplastic plate (HWP-3200), and the heating and softening temperature is 60-70℃, and a low-temperature thermoplastic plate can also be used.
