Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a silicone gel magnetic clamp. Background Art

[0002] Keloid refers to a benign and irreversible pathological change in damaged skin caused by excessive proliferation of fibroblasts. Clinically, it manifests as tough, dark red or purple nodules, cords or flaky masses that are higher than the skin surface, with or without obvious itching, pain or tenderness. Ear keloids often occur after ear piercing, trauma, surgery, and burns. When keloids appear on the ears, slight deformities can cause obvious discomfort to patients. In order to achieve ideal therapeutic effects in the treatment of ear keloids, multiple treatment methods must be used in combination. Among them, surgery is the basic treatment method. Simple surgical excision is prone to recurrence, while pressure therapy and silicone gel drug therapy are relatively effective treatment measures to prevent recurrence.

[0003] The use of silicone gel scar patches has a good preventive and therapeutic effect on hypertrophic scars. Existing scar patches need to be cut when used, and are easy to loosen and fall off. Repeated application of scar patches will reduce their adhesion. Scar patches need to be cut again when replaced, which causes waste and increases patient expenses. Metal ear clip scar patches that adjust the pressure through screws and springs are more cumbersome to wear. Utility Model Content

[0022] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0023] like Figures 1 to 3 As shown, an embodiment of the utility model proposes a silicone gel magnetic clamp, comprising a first layer, a second layer and a third layer, wherein the first layer is a breathable film layer 1, the second layer is a self-adhesive silicone gel layer 2, and the third layer is a release protective film layer 3, the first layer is covered on the second layer, and the second layer is covered on the third layer, wherein the first end of the self-adhesive silicone gel layer 2 is provided with a first magnetic suction sheet 21, and the second end of the self-adhesive silicone gel layer 2 is provided with a second magnetic suction sheet 22.

[0024] The silicone gel magnetic clip proposed in the embodiment of the utility model has a three-layer structure of a breathable film layer, a self-adhesive silicone gel layer, and a release protective film layer, and magnetic suction sheets are provided at both ends of the self-adhesive silicone gel layer. The magnetic force generated by the magnetic suction sheets acts on the two ends of the self-adhesive silicone gel layer to generate a pair of opposite forces, so that when the self-adhesive silicone gel layer covers the ear scar, it provides greater local pressure, and at the same time achieves the effect of softening scar tissue, inhibiting scar tissue proliferation, and making the scar flatter and lighter; this structure can easily achieve long-term compression treatment, does not need to be cut, is not easy to fall off, and has the advantages of being simple, practical, and low cost.

[0025] like Figures 1 to 3 As shown, in an optional embodiment of the present invention, the breathable film layer 1 and the self-adhesive silicone gel layer 2 are both in an 8-shape.

[0026] Specifically, the breathable film layer, the self-adhesive silicone gel layer and the release protective film layer are all in an 8-shape, so that the silicone gel magnetic clip fits the ear contour and meets the aesthetic requirements. The shape described in this embodiment is only an example. When used specifically, the shapes of the breathable film layer, the self-adhesive silicone gel layer and the release protective film layer can also be designed according to actual needs. The self-adhesive silicone gel layer uses a self-adhesive silicone gel material, which has strong viscosity and can be firmly bonded to the breathable film layer. Before the self-adhesive silicone gel layer is bonded to the breathable film layer, no primer operation is required. On the one hand, it reduces the processing cost and makes the process controllable. On the other hand, it also avoids the influence of the primer treatment on the viscosity of the gel.

[0027] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, the first magnetic attraction sheet 21 and the second magnetic attraction sheet 22 are both disc-shaped.

[0028] Specifically, in order to adapt to the shape of the self-adhesive silicone gel layer, the two magnetic suction sheets can be set to a disc shape to increase the magnetic attraction. According to actual needs, the two magnetic suction sheets can be set to other shapes, such as rectangles, triangles, etc., to improve adaptability.

[0029] In an optional embodiment of the present invention, the self-adhesive silicone gel layer 2 contains active substances.

[0030] Here, the active substance contained in the self-adhesive silicone gel layer is a widely used component for treating keloids. Combining the active substance with the structure of the silicone gel magnetic clip is conducive to improving the treatment effect of ear scars. Specifically, auxiliary materials such as penetration enhancers, fragrances and antipruritic factors can also be added to the self-adhesive silicone gel layer to improve the treatment effect. The penetration enhancer enables the active substance, which is a scar treatment active substance, to better penetrate into the scar tissue and play a therapeutic role. The antipruritic factor can inhibit the local itching caused by the change of the local wet environment caused by long-term application on the scar surface, increase the patient's adaptability, and improve the treatment effect. Among them, the penetration enhancer can be one or more of oleic acid, lanolin, eucalyptus oil, menthol, camphor, azone, sodium lauryl sulfate, Tween-80 and caprylic acid monoglyceride; the fragrance can be one or more of peppermint oil, orange peel oil, anise oil, citron oil, spearmint oil, onion oil; the antipruritic factor can be one or more of turpentine oil, bran oil, and black bean oil. Benzocaine, daclonin, novocaine, diphenhydramine, and pyrimethamine can also be dispersed in the self-adhesive silicone gel layer to expand the therapeutic range of the above drugs for the prevention and treatment of skin itching. The amount of the above active substances and / or excipients can be added according to actual needs.

[0031] In an optional embodiment of the present invention, the active substance includes at least one of silicone gel, glucocorticoid, and onion extract.

[0032] Specifically, the active substance may also be small molecule silicone. The specific components of the active substance may be selected according to actual needs.

[0033] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, the first magnetic attraction sheet 21 is embedded in the first end of the self-adhesive silicone gel layer 2, and the second magnetic attraction sheet 22 is embedded in the second end of the self-adhesive silicone gel layer 2.

[0034] Specifically, grooves can be opened at both ends of the self-adhesive silicone gel layer, and the magnetic suction sheet can be embedded in the grooves. After the release protective film layer is removed and the silicone gel magnetic clip is fixed to the ear, the magnetic suction sheet will not be visible, thereby improving the aesthetics. Here, the thickness of the magnetic suction sheet is less than the thickness of the self-adhesive silicone gel layer, so that the magnetic suction sheet does not directly contact the patient's skin and scar, and the silicone gel magnetic clip can be fixed to the surface of the ear scar to play a therapeutic role. Specifically, the magnetic suction sheet is located in the middle of the two ends of the self-adhesive silicone gel layer.

[0035] like Figure 2 As shown, in an optional embodiment of the utility model, the first end of the self-adhesive silicone gel layer 2 is provided with a first opening 211, the first magnetic suction sheet 21 is installed in the first opening 211, and the second end of the self-adhesive silicone gel layer 2 is provided with a second opening 221, and the second magnetic suction sheet 22 is installed in the second opening 221.

[0036] Here, through holes are provided at both ends of the self-adhesive silicone gel layer for installing the magnetic suction sheet, which is convenient for installing and removing the magnetic suction sheet. The magnetic suction sheet does not contact the breathable film layer and the release protective film layer, or the magnetic suction sheet can contact the breathable film layer but not the release protective film layer, which is convenient for removing the release protective film layer when using.

[0037] In an optional embodiment of the utility model, the thickness of the breathable film layer 1 is 0.1-0.3mm. The thickness of the self-adhesive silicone gel layer 2 is 1.8-2mm. The magnetic pressure range that can be generated by the first magnetic suction sheet 21 and the second magnetic suction sheet 22 is 24-30mmHg, and the diameter of the first magnetic suction sheet 21 and the second magnetic suction sheet 22 is about 10-12mm, and the thickness is 0.8-1mm. The length of the 8-shaped silicone gel magnetic clip is 60mm, the waist width is 10mm, the arc diameter of the front and back of the ear is 16-20mm, and the thickness is 2mm.

[0038] It should be noted that the thickness, length, diameter and other data mentioned above are exemplary illustrations for achieving the lightweight and beautiful effect of the silicone gel magnetic clamp; specifically, the diameter of the magnetic suction sheet is smaller than the self-adhesive silicone gel layer 2 of the arc portion to ensure the comfort of the surrounding skin and increase the pressure on the scar.

[0039] During specific use, the above data can be changed according to the area and shape of the ear scar, and the utility model does not impose any restrictions thereon.

[0040] like Figures 1 to 3 As shown, in an optional embodiment of the present invention, the area of ​​the breathable film layer 1 is the same as that of the self-adhesive silicone gel layer 2 .

[0041] Specifically, the areas of the breathable film layer, the self-adhesive silicone gel layer, and the release protective film layer are all the same, so as to improve safety and aesthetics.

[0042] In an optional embodiment of the present invention, the breathable film layer 1 is made of polyurethane or silicone.

[0043] Specifically, the polyurethane film can be a breathable polyurethane film to ensure good air permeability of the silicone gel magnetic clip. Polyurethane is a non-toxic and harmless environmentally friendly material that does no harm to human skin. Using a film made of polyurethane as a breathable film layer can improve safety. Silicone is resistant to high temperatures, corrosion, and has good softness. Using a breathable film layer made of silicone material can improve softness and extend service life.

[0044] In an optional embodiment of the present invention, the release protective film layer 3 is made of at least one of polycarbonate, polypropylene or plastic.

[0045] Specifically, the release protective film layer can be at least one of transparent polycarbonate, polypropylene or plastic, which can protect the cleanliness of the silicone gel magnetic clamp and provide support for the silicone gel magnetic clamp during transportation.

[0046] In an optional embodiment of the utility model, the self-adhesive silicone gel layer 2 is skin-colored, so as to achieve the invisible effect of the silicone gel magnetic clip and improve the aesthetics and adaptability of the patient.

[0047] In an optional embodiment of the utility model, the release protective film layer 3 completely covers the upper surface of the self-adhesive silicone gel layer 2, and is provided with a release opening to expose the self-adhesive silicone gel layer 2. This can ensure the cleanliness of the self-adhesive silicone gel layer 2 and facilitate use.

[0048] When using the silicone gel magnetic clip of the embodiment of the utility model, the wound and hands can be cleaned first, and then the release protective film layer 3 can be torn off, and the self-adhesive silicone gel layer 2 can be directly applied to the scar area of ​​the ear. The first magnetic suction sheet 21 and the second magnetic suction sheet 22 fixed to the self-adhesive silicone gel layer 2 are attracted to each other at opposite poles in front of the ear and behind the ear, generating a pair of opposing forces for fixing the silicone gel magnetic clip to the ear scar, which can effectively and continuously compress the ear scar, so that the active substance in the self-adhesive silicone gel layer 2 can effectively and continuously act on the scar area of ​​the ear, and generate safe and effective pressure to inhibit scar hyperplasia.

[0049] The silicone gel magnetic clip of the utility model embodiment is designed in an "8" shape based on the basic shape of the human auricle, which is arc-shaped, according to ergonomics, and fits the ear contour to achieve the purpose of sufficient pressure and minimal damage; the size of the magnetic clip is similar to that of a decorative earring, and the clip is skin-colored, which can effectively hide scars and beautify the affected area. These two structures work together to make the ear scar pressure clip beautiful in appearance and easier for patients to accept.

[0050] The silicone gel magnetic clip of the utility model embodiment has the following effects in inhibiting scar hyperplasia:

[0051] Silicone gel is a porous material, composed of a network structure of silicon atoms and oxygen atoms. This structure is not only waterproof, but also has excellent permeability to carbon dioxide and water vapor. Silicone gel reduces the loss of water in the stratum corneum through closed hydration, increases the hydration of the stratum corneum, and treats scar hyperplasia by reducing the loss of water in the ear affected area. Silicone gel can inhibit transforming growth factor β, reduce the growth of epidermal fibroblasts, and promote scar softening to achieve the purpose of treating scar hyperplasia. The characteristics of organic silicon are non-allergic, flexible bonding, and painless removal, combined with the "skin-like" "breathability", providing patients with an extremely comfortable use experience.

[0052] The disc-shaped magnetic suction pieces embedded at both ends of the self-adhesive silicone gel layer have the following effects in inhibiting scar hyperplasia:

[0053] Pressure causes a decrease in local tissue blood flow, and the inhibitor of collagenase, α2 myosin, decreases accordingly, which increases collagenase activity and accelerates collagen decomposition, leading to the rearrangement of spiral collagen and softening of scars. Applying a pressure higher than that of capillaries to the ear lesions can change the internal environment of the lesion tissue and put it in a state of hypoxia. Under hypoxia, the intracellular oxygen partial pressure decreases, the function of mitochondria decreases, and morphological changes occur at the same time, such as mitochondrial swelling and vacuolar degeneration, which lead to the inability of mitochondria to release energy during oxidative phosphorylation, resulting in the inhibition of fibroblast proliferation and the reduction of the ability to generate collagen fibers and matrix, which leads to thinning and softening of scars. The pressure applied to the ear lesions should be at least 24 mmHg, because sufficient pressure can counteract the venous pressure of the capillaries, but it should not be higher than 30 mmHg, because too high pressure will cause tissue necrosis due to ischemia. The pressure is more accurate, ensuring the safety and effectiveness of use.

[0054] The three-layer structure in the embodiment of the utility model has a moderate thickness, and the good air permeability of the scar patch is guaranteed through the specific effects between the layers. The utility model combines the three-layer structure with the anti-scar effective ingredients, and provides anti-scar drug treatment on the basis of physical therapy, providing greater local pressure, and can clamp the scar area constantly and evenly to prevent the healthy area from being compressed and causing poor blood flow, while achieving the effect of softening scar tissue, inhibiting scar tissue hyperplasia, and making the scar flat and light. The problem that the silicone gel dressing film is easy to fall off during use is solved, and it can be tightly adhered to the ear skin without gaps, and can be applied on the scar surface for a long time and continuously pressurized, which solves the problem that the scar patch is easy to fall off and needs secondary cutting. It is convenient and quick to wear, easy to use, and low in cost. It provides appropriate pressure on the scar area to reduce scar hyperplasia. At the same time, it has excellent air permeability and waterproofness, which is conducive to improving the treatment effect of hyperplastic scars.

[0055] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
