Description

Technical Field

[0001] The utility model relates to the technical field of burn and scald treatment equipment, in particular to a perioral scar tension and compression device. Background Art

[0002] During the treatment of burns and scalds, scars will appear after the skin tissue is repaired and healed. Especially when deep burns and scalds damage the deep dermis, hypertrophic scars or atrophic scars are very likely to form.

[0003] Whether it is a hypertrophic scar or an atrophic scar, scar treatment after healing is not only to improve the appearance, but more to avoid functional disorders caused by scar hyperplasia or atrophy.

[0004] The current scar treatment options include:

[0005] 1. Drug treatment: such as applying compound heparin sodium allantoin, vitamin E, silicone gel and other drugs on the scar surface to soften the scar, or using bleomycin, interferon, verapamil and other drugs for local injection to inhibit microscopic tissue proliferation;

[0006] 2. Physical therapy: such as compression, laser, radiation, cryotherapy, etc. Compression is currently the basis of all scar treatments and is also one of the most effective scar treatments;

[0007] 3. Surgical treatment: It is usually used as a treatment method when physical therapy and drug treatment are not effective. Because surgical treatment will cause new trauma, more serious scar hyperplasia may occasionally occur after the trauma heals. Therefore, this treatment method is often chosen when functional disorders occur.

[0008] In the process of scar treatment, through generations of improvements in treatment methods, it is currently recognized that the most significant and stable treatment effect is the comprehensive treatment method that combines drugs and physical therapy. Specifically, it is a comprehensive treatment method that mainly uses compression, supplemented by laser and drugs.

[0009] Compression therapy for scars is performed by wearing pressure garments (pressure garments in this field refer to wearable cloth products that can provide pressure to the scar area, usually including pressure head covers, pressure tops, pressure pants, pressure gloves, pressure foot covers and other cloth products worn on any part of the body). As the pressure garments press the scar, the capillaries shrink due to the pressure, causing relative ischemia of the scar tissue and degeneration of the myofibroblasts.

[0010] However, due to the limitation of human bone structure, the pressure garment cannot fit all the scar parts to provide appropriate pressure as imagined. In practice, due to the structure of the zygomatic bone and mandible, the zygomatic bone and mandible support the pressure garment. At this time, the pressure garment cannot provide effective pressure to the perioral area, especially the corners of the mouth. As a result, after the face is burned or scalded, the corners of the mouth will cause functional disorders such as speaking and eating due to scar hyperplasia or contracture.

[0011] To solve the above problems, doctors usually choose to pad the corners of the patient's mouth and cheeks with silicone pads or cotton cloth to increase the thickness of the area, that is, to provide effective support, so that the pressure of the pressure garment can be applied to the scar area. Although the above method can inhibit scar hyperplasia to a certain extent, if it can be further improved and the impact of scars on the function of the patient's perioral area can be further reduced, it is extremely important for the patient's rehabilitation effect.

[0035] The following is a detailed description of the embodiments of the utility model in conjunction with the accompanying drawings. It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Scars will form at the corners of the mouth after burns and scalds heal. Scars are inelastic, so whether it is hyperplasia or contracture, it will cause the mouth to open and close smaller, which will affect speaking or eating. Therefore, the most important goal of scar treatment is to help patients restore oral function to the maximum extent and reduce the impact of scars on future life.

[0037] In many years of work experience, except for a very small number of cases of deep burns and scalds on a small area of ​​the mouth, there are more cases of large-area facial burns and scalds. Therefore, scar treatment is not only for the mouth, but also for the face, top of the head, forehead and other scars. Therefore, when treating perioral scars, it should be used in conjunction with pressure clothing. The more common pressure clothing used to treat head scars is found in communication with patients and post-treatment observations. The pressure at the corners of the mouth and cheeks is too small. Although it can be improved appropriately through fitting and cutting, it is usually difficult for patients to afford the customization fee of nearly 10,000 yuan. In actual treatment, a more practical method is generally chosen, such as inserting silicone pads or cotton pads between the pressure clothing and the scar to fill the insufficient force position, and at the same time, let the patient do more mouth opening exercises to improve the oral function. The best way to open the mouth is to let the patient keep the mouth open to the maximum for 24 hours, which can theoretically greatly improve the impact of scars on oral function. However, there are many problems in actual operation. First, the treatment period for patients after experiencing facial burns is as long as nearly a month, and they also have to face scar treatment for more than a year or even several years, and the patient's cooperation is low. Second, keeping the mouth open for a long time is a great test for the patient's mood and body, and the feasibility is low.

[0038] like Figure 1-6 As shown, in some illustrative embodiments, a perioral scar tension and compression device is provided, which is mainly used for physical treatment of perioral scars and specifically includes: a guide cross bar 1, an expansion member 2 and a force-applying mechanism 3.

[0039] The guide crossbar 1 plays a guiding and supporting role, and the material used can be selected to be a metal with low weight and not easy to rust, such as aluminum alloy.

[0040] There are two expansion members 2, which are arranged in parallel on the guide cross bar 1 and can move along the rod body of the guide cross bar 1. They apply a certain pressure to the two corners of the mouth around the mouth, causing the capillaries to shrink due to pressure, resulting in relative ischemia of the scar tissue.

[0041] Corresponding to the two expanders 2, the force-applying mechanism 3 is arranged on the guide cross bar 1, which is used to pull the two expanders 2 away from each other, so as to achieve the purpose of lateral pushing and pulling of the mouth, maintain the degree of opening of the mouth, and at the same time, on the basis of lateral pushing and pulling, apply pressure to the corners of the mouth to reduce the degree of congestion of scar tissue.

[0042] The expansion piece 2 includes a column seat 201 and a bushing 202 .

[0043] A guide column groove 203 is provided on the column seat 201, and a bushing 202 is arranged in the guide column groove 203. The guide cross bar 1 passes through the guide column groove 203 so that the expansion piece 2 is sleeved on the rod body of the guide cross bar 1. The design of the bushing 202 is to increase the strength of the expansion piece 2 to ensure that the expansion piece 2 will not be deformed or broken under the force of the force-applying mechanism 3 for a long time.

[0044] The end of the column base 201 facing the inside of the oral cavity is bent outward to form an anti-slip portion 204, where the outward refers to the direction in which the two expansion members 2 move away from each other. An obtuse angle a is formed between the anti-slip portion 204 and the main body of the column base 201, so that the anti-slip portion 204 and the column base 201 together form a hook structure, which is used to hook the corner of the mouth and the area extending from the corner of the mouth to the cheek when a part of the expansion member 2 is inserted into the mouth.

[0045] Since the position point where the force applying mechanism 3 applies the push-pull force is at the end of the column seat 201 facing the outside of the oral cavity, and a gap must be left between the outer wall of the guide crossbar 1 and the inner wall of the bushing 202 (the gap is used to facilitate expansion).

[0046] The first is to prevent the lateral movement of the expansion member 2, and the second is to prevent the movement of debris in the gap after long-term use. Therefore, when the column base 201 is subjected to the push-pull force from the force-applying mechanism 3, it will tilt, causing the expansion member 2 to easily fall out of the mouth. The hook structure formed by the anti-falling part 204 and the column base 201 in this embodiment can avoid the above situation.

[0047] Appear, ensure the stability of the patient wearing the perioral scar tension and compression device.

[0048] The end of the anti-slip portion 204 is bent upward to form a gum avoidance portion 205. The upward bending here means that after the expansion piece 2 is worn, the anti-slip portion 204 extends and bends in the direction of the zygomatic bone, and finally forms the gum avoidance portion 205. An obtuse angle b is formed between the gum avoidance portion 205 and the anti-slip portion 204. After the anti-slip portion 204 enters the mouth, it is located between the teeth and the facial tissue. The formation of the gum avoidance portion 205 allows the expansion piece 2 to be inserted. The outer surface of the maxillary teeth is used as a support point, and it extends to the outside of the upper gum and presses against the cheek, thereby avoiding the upper and lower gums. The above structural design can firstly avoid the discomfort caused by long-term wearing after the expansion piece 2 presses the gums, and secondly, the cheek area is lifted up, thereby increasing the pressure between the scar tissue in the cheek area and the pressure headgear, and ensuring the therapeutic effect of the pressure garment.

[0049] The outer side of the anti-slip part 204 is provided with a pressing platform 2041 in contact with the inner side of the mouth corners, and the pressing platform 2041 pushes the mouth corners to the upper and lower sides, playing a longitudinal push-pull effect. The present application applies a lateral and longitudinal push-pull force to the mouth corners through the expansion piece 2, so that the patient can ensure that the mouth corners are continuously compressed and stretched when the mouth is half closed, and at the same time, the purpose of maintaining the mouth open and expanded for a long time is achieved. Therefore, the present application reduces the discomfort of the patient while ensuring the treatment effect.

[0050] After wearing the perioral scar tension and compression device of the present application, the patient can keep his mouth half-closed, greatly reducing the impact on his normal life. Figure 1 When the sample is worn as shown, the impact on speaking is within an acceptable range, and normal basic communication can be achieved; after wearing, the patient's upper and lower teeth can bite normally, and there is no need to open the mouth into an O shape. Compared with the existing mouth expansion method, the evaporation rate of saliva in the oral cavity can be reduced, and the symptoms of dry mouth can be reduced; during sleep, there is only drooling due to loose lip closure, and there are no other abnormal phenomena. Therefore, under certain conditions, such as rapid scar hyperplasia or severe scar hyperplasia, 24 hours of high-intensity wearing can be achieved.

[0051] The present application also has the advantage of being easy to wear. When you need to eat or drink, you can take the expander 2 out of your mouth and then eat or drink normally. After finishing, you can directly insert the expander 2 into your mouth to perform continuous perioral scar compression and mouth expansion.

[0052] The present application can also achieve the purpose of physical therapy in combination with pressure clothing, that is, increasing the pressure between the scar tissue in the cheek area and the pressure headgear to ensure the therapeutic effect of the pressure clothing. At the same time, the structural design of the present application is more in line with the human body structure and is more comfortable to wear.

[0053] The column seat 201 and the anti-slip portion 204 are both cylindrical structures, and a sinking groove is provided on the outer side of the anti-slip portion 204 to form a pressing platform 2041, and arc transition surfaces 2042 are provided at the outer edges of both sides of the pressing platform 2041. The gum avoidance portion 205 is a truncated cone structure, and a hemispherical buckle cover 206 is provided on the top of the gum avoidance portion 205. The purpose of the above structural design is to make the expansion piece 2 more compatible with the shape of the oral periphery, avoid discomfort to the patient when wearing it, and better conform to the human oral structure.

[0054] The connection between the column seat 201 and the anti-slip portion 204 and the connection between the anti-slip portion 204 and the gum avoidance portion 205 are all smoothly transitioned to avoid discomfort caused by structural edges and corners.

[0055] The column base 201, the anti-slip portion 204 and the gum avoidance portion 205 are made of gypsum, and the three are kneaded and formed by gypsum, that is, an integrated structure. Gypsum is a commonly used nursing material with good properties, such as high strength, light weight, strong antibacterial properties, non-toxicity, etc., and it is easy to customize according to the patient's requirements. The bushing 202 is made of stainless steel to ensure the strength of the column base 201. The hemispherical buckle cover 206 is made of rubber, which is specifically glued to the end of the gum avoidance portion 205 with glue, and has a deformable property, which further improves the wearing comfort.

[0056] Two implementations of the force applying mechanism 3 are described below:

[0057] The first implementation method:

[0058] Two symmetrical S-shaped fastening hooks 101 are arranged at both ends of the guide crossbar 1. At this time, the force-applying mechanism 3 is an elastic rope, one end of which is bound to the S-shaped fastening hook 101, and the other end of which is bound to the end of the column seat 201 facing the outside of the oral cavity. Therefore, the force-applying mechanism 3 can apply a pulling force outward to the two expansion members 2 to achieve the purpose of assisting oral expansion. Furthermore, the end of the column seat 201 facing the outside of the oral cavity is bent downward to form a binding portion 207, and an annular groove 2071 is provided on the binding portion 207. The elastic rope is bound in the annular groove 2071, which can ensure the connection stability and the force balance.

[0059] The second implementation method:

[0060] Tightening rods 102 are provided at both ends of the guide crossbar 1, and mounting plates 103 are provided at the ends of the tightening rods 102. At this time, the force-applying mechanism 3 includes: a screw rod 301 and two sets of adjusting parts provided on the screw rod 301, and the two sets of adjusting parts correspond to two expansion members 2 respectively. The two ends of the screw rod 301 are respectively connected to the mounting plates 103 located at both ends of the guide crossbar 1, and each set of adjusting parts is composed of two nuts 302, and the two nuts 302 are respectively located on both sides of the end of the column seat 201 facing the outside of the oral cavity. By screwing the nut 302, the position of the nut 302 on the guide crossbar 1 is adjusted, and then the position of the expansion member 2 on the guide crossbar 1 is adjusted, and the nut 302 plays a limiting role, that is, after the expansion member 2 reaches the desired position, it cannot be displaced under the limitation of the nut 302, thereby realizing the application of a force pushing outward to the two expansion members 2, so as to achieve the purpose of assisting the expansion of the oral cavity.

[0061] Furthermore, the width of the end of the column base 201 facing the outside of the oral cavity gradually decreases to form a flat plate 208. A through hole is opened on the plate 208, and the screw 301 passes through the through hole. Two nuts 302 are respectively located on both sides of the plate 208, one is to ensure the force balance, and the other is to facilitate the adjustment of the position of the expansion piece 2 through the nut 302.

[0062] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
