Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an adaptive elastic pressure autonomous training device for scar repair. Background Art

[0002] Scar repair is an important topic in the field of rehabilitation medicine, especially for patients with burns, trauma or surgery, where scar tissue hyperplasia is often accompanied by itching, pain and limited joint movement. Traditional scar repair methods mainly include pressure therapy, silicone preparations, laser therapy and rehabilitation training, but existing technologies still have significant limitations: Pressure therapy lacks adaptability: Traditional pressure devices (such as elastic bandages and pressure garments) need to be customized according to the patient's body shape, but lack dynamic adjustment capabilities and are difficult to adapt to changes in limb dimensions during treatment (such as edema subsidence or muscle atrophy). This can easily lead to uneven pressure or local excessive compression, affecting the treatment effect and increasing patient discomfort.

[0003] The disconnect between functional training and massage: Scar repair requires a combination of passive massage and active functional training to promote tissue remodeling. However, existing devices mostly focus on a single function (such as massage only or pressure only) and lack an integrated design. Patients need to switch between different devices, which reduces treatment compliance.

[0004] Defects in human-computer interaction comfort: If the material of the device that comes into long-term contact with the skin has poor biocompatibility or insufficient breathability, it can easily cause skin irritation; at the same time, the traditional fixed design may aggravate friction in the scar area and increase discomfort when the patient actively moves (such as clenching a fist).

[0005] In summary, the present invention addresses the deficiencies of existing scar repair devices and proposes an adaptive elastic pressure autonomous training device for scar repair. Summary of the Invention

[0006] The present invention provides an adaptive elastic pressure self-training device for scar repair. By adopting a patch made of medical-grade TUP material, the material has high biocompatibility, lasting elasticity, and breathable and waterproof properties. Long-term contact with the skin can reduce the risk of allergies. It is fixed with Velcro and adapts to different palm sizes. In addition, the gear and flower gear limiting mechanism simplifies the adjustment process. The patient can quickly adjust the position of the clamp by pulling the gear, and it automatically locks after release, which is easy to operate. Clinical feedback shows that this design significantly reduces the skin irritation and operation complexity of patients when using traditional devices. It is particularly suitable for scar patients who require long-term treatment, improves the overall treatment experience, and solves the problems raised in the background technology.

[0007] The technical solutions of the present invention are as follows: An adaptive elastic compression self-training device for scar repair, comprising: support blocks, there are two support blocks in total, one end of each support block is fixedly connected with an inclined block, and an arc-shaped groove one is opened in the middle of the inclined block for placing the patient's hand. A massage component is arranged between the two support blocks. One end of one of the support blocks close to the massage component is fixedly connected with a fixed block. An adaptive component is arranged in the massage component. A hand training component is arranged at one end of one of the support blocks. The top of the fixed block is fixedly connected with a square block. Both the fixed block and the square block are provided with U-shaped grooves, and the two U-shaped grooves are interconnected to facilitate the up and down sliding of the arc-shaped block two. A circular groove is opened on one side of the fixed block, and a flower-shaped circular groove is opened on one side of the fixed block in the circular groove. One end of the fixed block far away from the square block is fixedly connected with an arc-shaped block.

[0008] Further, the massage component includes an upper clamping block and a lower clamping block slidably connected to the fixed block. The upper clamping block and the lower clamping block are both divided into two pieces. An arc-shaped groove two is opened on the opposite side of each upper clamping block and each lower clamping block. A circular groove is opened on the opposite side of the upper clamping block and the lower clamping block, and a massage head is arranged in the circular groove.

[0009] Further, a slope is arranged at the bottom of the opposite side of each upper clamping block in the arc-shaped groove two. If the arm dimension of the patient's arm is small, the patient closes the upper clamping blocks and the lower clamping blocks on both sides. The cylinder contacts the slope at one end of the arc-shaped groove two, and the cylinder is gradually slid into the cylinder groove through the slope and compresses the spring.

[0010] Further, one end of one of the upper clamping blocks is fixedly connected with an arc-shaped rack one, and the arc-shaped rack one extends to the other upper clamping block. The back of the other upper clamping block is fixedly connected with an arc-shaped rack two, and the connections between the arc-shaped rack one and the arc-shaped rack two and the upper clamping blocks are both set in a telescopic mode, so that the teeth of the arc-shaped rack one and the arc-shaped rack two will not be separated from the gear when the upper clamping blocks on both sides slide up and down. A gear is rotatably connected between the arc-shaped rack one and the arc-shaped rack two on the fixed block. One end of the gear is fixedly connected with a fixed rod having the same size as the circular groove. The fixed rod is slidably connected in the circular groove. One end of the fixed rod far away from the gear is fixedly connected with a flower-shaped gear, and the flower-shaped gear is slidably connected in the flower-shaped circular groove.

[0011] Further, the adaptive component includes an upper arc-shaped block one slidably connected in the arc-shaped groove two of the upper clamping block. One end of the upper arc-shaped block one is slidably connected to the fixed block, and a lower arc-shaped block two slidably connected to the arc-shaped groove two in the lower clamping block. The lower arc-shaped block two is fixedly connected to the fixed block.

[0012] Furthermore, a cylindrical groove is provided on the opposite side of the upper arc block 1 and the lower arc block 2, a cylinder is slidably connected in the cylindrical groove, a spring is fixedly connected between the cylinder and the cylindrical groove, a driving motor is provided at one end of the cylinder and the massage head, and the end of the cylinder away from the cylindrical groove and the massage head are both made of silicone. The massage head uses the soft touch of the silicone material to soothe the scar area on the patient's arm, promote blood circulation and tissue repair, and the silicone material at the end of the cylinder contacts the skin synchronously, assisting the massage and enhancing the elastic pressurization effect.

[0013] Furthermore, the hand training component includes a fitting piece fixedly connected to the end of the fixing block away from the upper clamping block, a transition piece is fixedly connected between the metacarpophalangeal joint and the first finger joint of the fitting piece, and the material of the fitting piece is medical-grade TUP material, which has high biocompatibility, lasting elasticity, breathability and waterproofness, is suitable for long-term contact with the skin, and can reduce the patient's discomfort. Velcro is fixedly connected to both sides of the finger part and the palm part of the fitting piece, which is convenient for fitting different patient palm widths and finger sizes, and a micro massage head is provided inside the fitting piece to fit the different patient palm widths and finger sizes. The micro massage head arranged inside the fitting can perform targeted massage on the patient's hands, further relieving scars and muscle fatigue on the hands. The arc block is rotatably connected to a rotating plate at one end away from the fixed block. One end of the rotating plate is located at the top of the metacarpophalangeal joint of the fitting piece, and the other end of the rotating plate is fixedly connected to the middle part of the fitting piece with a transition piece. When the patient makes a fist, the metacarpophalangeal joint pushes the rotating plate to rotate, and the rotating plate relaxes to drive the transition piece downward, thereby relaxing the fitting pieces at both ends of the first finger joint, thereby relieving the patient's feeling of tightness when making a fist and reducing the friction of the fitting piece on the patient's injured part.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention realizes precise dynamic control of pressure through the coordinated adjustment system of double upper clamps and double lower clamps and the cylinder and spring adaptive components. When the patient's arm dimensions are large, the upper and lower clamps can expand outward to completely wrap the limb; when the dimensions are small, the upper and lower clamps shrink inward, and the cylinder guides the compression spring through the inclined surface to form an elastic buffer. This design avoids the rigid compression problem of traditional devices, ensures uniform pressure distribution, improves the treatment effect and reduces patient discomfort. In clinical applications, this technology can adapt to dimensional changes such as edema subsidence or muscle atrophy during treatment, significantly improving the adaptability and comfort of pressure therapy.

[0015] 2. The present invention can gently massage the arm and hand simultaneously through the massage head and the micro massage head made of silica gel, promoting blood circulation. At the same time, through the linkage mechanism of the rotating plate and the transition piece, when the patient makes a fist, the metacarpophalangeal joint pushes the rotating plate to rotate, relaxing the traction on the fitting piece, relieving the tight feeling and reducing scar friction. This design combines passive massage with active training, improving the treatment efficiency. The patient can complete comprehensive rehabilitation without switching equipment, significantly improving the treatment compliance.

[0016] 3. The present invention uses a fitting piece made of medical-grade TUP material, which has high biocompatibility, long-lasting elasticity, and breathable and waterproof characteristics. Long-term contact with the skin can reduce the risk of allergy.配合魔术贴固定,适应不同手掌尺寸,此外,齿轮和花齿轮限位机构简化了调节流程,患者可通过拉动齿轮快速调整夹块位置,释放后自动锁定,操作便捷,临床反馈显示,该设计显著降低了患者使用传统装置时的皮肤刺激感和操作复杂性,尤其适用于需长期治疗的瘢痕患者,提升了整体治疗体验。With the cooperation of the magic tape for fixation, it can adapt to different palm sizes. In addition, the gear and the flower gear limiting mechanism simplify the adjustment process. The patient can quickly adjust the position of the clamping block by pulling the gear and it will automatically lock after release, with convenient operation. Clinical feedback shows that this design significantly reduces the skin irritation and operation complexity when patients use traditional devices, especially suitable for scar patients who need long-term treatment, improving the overall treatment experience.

[0021] As a technical solution of the present invention, the massage component 2 comprises an upper clamping block 21 and a lower clamping block 22 which are slidably connected to the fixed block 3. The upper clamping block 21 and the lower clamping block 22 are both divided into two pieces. An arc-shaped groove 23 is opened on the opposite side of each upper clamping block 21 and each lower clamping block 22. A circular groove 24 is opened on the opposite side of the upper clamping block 21 and the lower clamping block 22. A massage head 25 is arranged in the circular groove 24.

[0022] As a technical solution of the present invention, a slope 231 is arranged at the bottom of each upper clamping block 21 on the opposite side of the arc-shaped groove 23. If the arm dimension of the patient's arm is small, the patient closes the upper clamping blocks 21 and the lower clamping blocks 22 on both sides. The cylinder 422 contacts the slope 231 at one end of the arc-shaped groove 23, and the cylinder 422 is gradually slid into the cylindrical groove 421 through the slope 231, and the spring 423 is compressed.

[0025] As a technical solution of the present invention, a cylindrical groove 421 is provided on the opposite side of the upper arc block 1 41 and the lower arc block 2 42, and a cylinder 422 is slidably connected in the cylindrical groove 421. A spring 423 is fixedly connected between the cylinder 422 and the cylindrical groove 421. The cylinder 422 and one end of the massage head 25 are both provided with a driving motor, and the end of the cylinder 422 away from the cylindrical groove 421 and the massage head 25 are both made of silicone. The massage head 25 uses the soft touch of the silicone material to soothe the scar area on the patient's arm, promote blood circulation and tissue repair, and the silicone material at the end of the cylinder 422 synchronously contacts the skin, assisting massage and enhancing the elastic pressurization effect.

[0026] As a technical solution of the present invention, the hand training component 5 includes a fitting sheet 51 fixedly connected to the end of the fixing block 3 away from the upper clamping block 21, and a transition sheet 52 is fixedly connected between the metacarpophalangeal joint and the first finger joint of the fitting sheet 51. The material of the fitting sheet 51 is medical-grade TUP material, which has high biocompatibility, durable elasticity, breathable and waterproof, suitable for long-term contact with the skin, and can reduce the patient's discomfort. The finger part and both sides of the palm part of the fitting sheet 51 are fixedly connected with Velcro 53, which is convenient for fitting different patient palm widths and finger sizes, and a micro massage head is provided inside the fitting sheet 51 to fit the different patient palm widths and finger sizes. The micro massage head arranged inside the fitting piece 51 can perform targeted massage on the patient's hands, further relieving scars and muscle fatigue on the hands. The arc block 35 is rotatably connected to the rotating plate 54 at one end away from the fixed block 3. One end of the rotating plate 54 is located at the top of the metacarpophalangeal joint of the fitting piece 51, and the other end of the rotating plate 54 is fixedly connected to the transition piece 52 in the middle of the fitting piece 51. When the patient makes a fist, the metacarpophalangeal joint pushes the rotating plate 54 to rotate, and the rotating plate 54 relaxes to drive the transition piece 52 to move downward, thereby relaxing the fitting piece 51 at both ends of the first finger joint, thereby relieving the tightness of the patient when making a fist and reducing the friction of the fitting piece 51 on the patient's injured part.

[0027] Working principle: like Figure 1-Figure 2 and Figure 3-Figure 5 As shown, the user adjusts the position between the upper clamping block 21 and the lower clamping block 22 according to the width of his own arm, first slides the upper arc block 1 41 downward in the square groove, so that the upper arc block 1 41 and the lower arc block 2 42 clamp the upper and lower parts of the arm, then pulls the gear 223 outward to drive the flower gear 225 to slide out of the flower circular groove 34, and then pulls the upper clamping block 21 and the lower clamping block 22, which are provided with an arc rack 1 211 on one side, to one side, and the arc rack 1 211 drives the gear 223 to rotate, and the gear 223 drives the arc rack 225 to slide out of the flower circular groove 34. The second bar 222 slides to the other side, driving the upper clamping block 21 and the lower clamping block 22 on the other side to move synchronously, so that the upper clamping blocks 21 and the lower clamping blocks 22 on both sides move away from each other, so that they completely wrap the arm. Then, the gear 223 is pushed inward, so that the flower gear 225 is again stuck in the flower circular groove 34, limiting the upper clamping blocks 21 and the lower clamping blocks 22 on both sides; at the same time, the cylinder 422 and the spring 423 lose the restriction of the arc groove 23 and slide out to the end away from the cylindrical groove 421, so that they are in full contact with the patient's skin. If the patient's arm is small, the patient moves the upper clamping block 21 and the lower clamping block 22 on both sides closer to each other, and the cylinder 422 contacts the inclined surface 231 at one end of the arc groove 23, and gradually slides the cylinder 422 into the cylindrical groove 421 through the inclined surface 231, compressing the spring 423.

[0028] like Figure 1-Figure 3As shown, the patient's hand is then fitted to the fitting sheet 51 through the Velcro 53, and then the motor and micro motor are started to drive the massage head 25 to massage the patient's arm. The soft touch of the silicone material is used to soothe the scar area on the patient's arm, thereby promoting blood circulation and tissue repair. The silicone material at the end of the cylinder 422 simultaneously contacts the skin, assisting in massage and enhancing the elastic pressurization effect. The patient's hand will feel numbness during long-term treatment. When the patient wants to make a fist to relieve the numbness, the patient's metacarpophalangeal joint touches one end of the rotating plate 54 during the fist-making process and pushes it upward. At this time, the other end of the rotating plate 54 rotates toward the finger and relaxes the traction on the transition sheet 52. After the transition sheet 52 is relaxed, the pressure on the fitting sheet 51 at both ends of the first finger joint is reduced, relieving the tightness when making a fist, while reducing the friction between the fitting sheet 51 and the scar, thereby improving training comfort.
