Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adaptive elastic pressure self-training device for scar repair. Background Technology

[0002] Scar repair is an important topic in rehabilitation medicine, especially for patients with burns, trauma, or post-operative conditions. Scar tissue hyperplasia is often accompanied by problems such as itching, pain, and limited joint mobility. Traditional scar repair methods mainly include pressure therapy, silicone preparations, laser therapy, and rehabilitation training, but current technologies still have significant limitations.

[0003] Pressure therapy is not adaptable: Traditional pressure devices (such as elastic bandages and pressure garments) need to be customized according to the patient's body shape, but they 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 excessive local compression, affecting the treatment effect and increasing patient discomfort.

[0004] 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 often focus on a single function (such as massage only or pressure only) and lack integrated design. Patients need to switch between different devices, which reduces treatment compliance.

[0005] Human-computer interaction comfort defects: If the material of the device that is in long-term contact with the skin has poor biocompatibility or insufficient breathability, it is easy to cause skin irritation; at the same time, the traditional fixed design may aggravate friction in the scar area when the patient actively moves (such as clenching a fist), which will aggravate discomfort.

[0006] In summary, this invention addresses the shortcomings of existing scar repair devices by proposing an adaptive elastic pressure autonomous training device for scar repair. Summary of the Invention

[0007] This invention provides an adaptive elastic pressure self-training device for scar repair. It utilizes a medical-grade TUP material for the adhesive patch, which boasts high biocompatibility, durable elasticity, and breathability and waterproof properties, reducing the risk of allergies with prolonged skin contact. Combined with Velcro for fixation, it adapts to different hand sizes. Furthermore, a gear and spiral gear limiting mechanism simplifies the adjustment process; patients can quickly adjust the clamp position by pulling the gears, and it automatically locks upon release, making operation convenient. Clinical feedback shows that this design significantly reduces skin irritation and operational complexity compared to traditional devices, making it particularly suitable for scar patients requiring long-term treatment and improving the overall treatment experience, thus addressing the problems mentioned in the background art.

[0008] The technical solution of this invention is as follows:

[0009] An adaptive elastic pressure self-training device for scar repair includes: a support block, two support blocks in total, an inclined block fixedly connected to one end of each support block, an arc-shaped groove in the middle of the inclined block for placing the patient's hand, a massage component between the two support blocks, a fixing block fixedly connected to one end of one support block near the massage component, an adaptive component inside the massage component, and a hand training component at one end of one of the support blocks;

[0010] A square block is fixedly connected to the top of the fixed block. Both the fixed block and the square block have an incline groove. The two incline grooves are interconnected to facilitate the sliding of the arc-shaped block. A circular groove is provided on one side of the fixed block. A floral circular groove is provided on one side of the circular groove. An arc-shaped block is fixedly connected to the end of the fixed block away from the square block.

[0011] Furthermore, 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 each divided into two parts. Each upper clamping block and the lower clamping block have an arc-shaped groove on their opposite sides and a circular groove on their opposite sides. A massage head is disposed in the circular groove.

[0012] Furthermore, each of the upper clamping blocks has an inclined surface at the bottom of the opposite side of the arc-shaped groove. If the patient's arm is small, the patient will bring the upper and lower clamping blocks on both sides closer to each other, and the cylinder will contact the inclined surface at one end of the arc-shaped groove. The cylinder will gradually slide into the cylindrical groove through the inclined surface and compress the spring.

[0013] Furthermore, one end of one of the upper clamping blocks is fixedly connected to an arc-shaped rack, which extends to the other upper clamping block. The back of the other upper clamping block is fixedly connected to an arc-shaped rack, and the connection points of the arc-shaped racks and the upper clamping blocks are both designed to be telescopic, so that the locking teeth of the arc-shaped racks do not separate from the gear when the upper clamping blocks slide up and down. A gear is rotatably connected between the arc-shaped racks and the arc-shaped rack on the fixed block. One end of the gear is fixedly connected to a fixed rod of the same size as the circular groove. The fixed rod is slidably connected in the circular groove. The end of the fixed rod away from the gear is fixedly connected to a flower gear, which is slidably connected in the flower-shaped circular groove.

[0014] Furthermore, the adaptive component includes an upper arc-shaped block 1 slidably connected within the arc-shaped groove 2 within the upper clamping block, one end of the upper arc-shaped block 1 being slidably connected to the fixed block, and a lower arc-shaped block 2 slidably connected to the arc-shaped groove 2 within the lower clamping block, the lower arc-shaped block 2 being fixedly connected to the fixed block.

[0015] Furthermore, a cylindrical groove is provided on one side of the upper arc-shaped block one and the lower arc-shaped block two opposite to each other. A cylinder is slidably connected in the cylindrical groove. A spring is fixedly connected between the cylinder and the cylindrical groove. A drive motor is provided at one end of both the cylinder and the massage head. The end of the cylinder away from the cylindrical groove and the massage head are both made of silicone. The massage head provides a soothing massage to the scar area of ​​the patient's arm through the soft touch of the silicone material, promoting blood circulation and tissue repair. The silicone material at the end of the cylinder simultaneously contacts the skin, assisting in the massage and enhancing the elastic pressure effect.

[0016] 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. The fitting piece is made of medical-grade TUP material, which has high biocompatibility, long-lasting elasticity, breathability, and waterproofness, making it suitable for long-term skin contact and reducing patient discomfort. Velcro is fixedly connected to both sides of the finger and palm portions of the fitting piece to facilitate fitting different patient hand widths and finger sizes. The fitting piece also has a micro-massage head inside. The micro-massage head inside the patch can provide targeted massage to the patient's hand, further relieving hand scars and muscle fatigue. The end of the arc-shaped block away from the fixed block is rotatably connected to a rotating plate. One end of the rotating plate is located at the top of the metacarpophalangeal joint of the patch, and the other end of the rotating plate is fixedly connected to a transition piece in the middle of the patch. When the patient clenches their fist, the metacarpophalangeal joint pushes the rotating plate to rotate, and the rotating plate relaxes, causing the transition piece to move down, thereby relaxing the patches at both ends of the first finger joint, thus relieving the tightness when the patient clenches their fist and reducing the friction of the patch on the patient's injury.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention achieves precise dynamic control of pressure through a coordinated adjustment system of double upper and double lower clamps, along with an adaptive assembly of a cylinder and spring. When the patient's arm is large, the upper and lower clamps can expand outward to completely enclose the limb; when the arm is small, the upper and lower clamps contract inward, and the cylinder guides the compression spring through an inclined plane to form an elastic buffer. This design avoids the rigid compression problem of traditional devices, ensures uniform pressure distribution, improves treatment effectiveness while reducing patient discomfort. In clinical applications, this technology can adapt to changes in dimensionality such as edema reduction or muscle atrophy during treatment, significantly improving the adaptability and comfort of pressure therapy.

[0019] 2. This invention provides a gentle silicone massage to the arms and hands simultaneously via a massage head and a mini massage head, promoting blood circulation. Simultaneously, through a linkage mechanism between the rotating plate and the transition plate, the patient's metacarpophalangeal joints push the rotating plate when making a fist, relaxing the traction on the adhesive patch, relieving tension, and reducing scar friction. This design combines passive massage with active training, improving treatment efficiency. Patients can complete comprehensive rehabilitation without switching devices, significantly improving treatment compliance.

[0020] 3. This invention uses a medical-grade TUP material for the adhesive patch, which has high biocompatibility, long-lasting elasticity, and breathable and waterproof properties, reducing the risk of allergies with long-term skin contact. Combined with Velcro for fixation, it adapts to different hand sizes. Furthermore, the gear and spiral gear limiting mechanism simplifies the adjustment process; patients can quickly adjust the clamp position by pulling the gears, and it automatically locks after release, making operation convenient. Clinical feedback shows that this design significantly reduces skin irritation and operational complexity compared to traditional devices, making it particularly suitable for scar patients requiring long-term treatment and improving the overall treatment experience.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] like Figures 1-5 As shown, the present invention provides an adaptive elastic pressure self-training device for scar repair, comprising: a support block 1, wherein two support blocks 1 are provided, one end of the support block 1 is fixedly connected to an inclined block 11, the middle of the inclined block 11 is provided with an arc-shaped groove 12 for placing the patient's hand, a massage component 2 is provided between the two support blocks 1, one of the support blocks 1 is fixedly connected to a fixing block 3 at the end near the massage component 2, an adaptive component 4 is provided inside the massage component 2, and one end of the support block 1 is provided with a hand training component 5;

[0030] A square block 31 is fixedly connected to the top of the fixing block 3. Both the fixing block 3 and the square block 31 are provided with an incised groove 32.

A floral circular groove 34 is provided on one side of the circular groove 33. An arc-shaped block 35 is fixedly connected to the end of the fixing block 3 away from the square block 31.

[0031] As a technical solution of the present invention, the massage component 2 includes an upper clamping block 21 and a lower clamping block 22 slidably connected to the fixed block 3. The upper clamping block 21 and the lower clamping block 22 are each divided into two parts. Each upper clamping block 21 and the lower clamping block 22 has an arc-shaped groove 23 on the opposite side. The upper clamping block 21 and the lower clamping block 22 have a circular groove 24 on the opposite side. A massage head 25 is disposed in the circular groove 24.

[0032] As a technical solution of the present invention, each of the upper clamping blocks 21 is provided with an inclined surface 231 at the bottom of the opposite side of the arc groove 23. If the patient's arm dimension is small, the patient will bring the upper clamping blocks 21 and lower clamping blocks 22 on both sides closer to each other, and the cylinder 422 will contact the inclined surface 231 at one end of the arc groove 23. The cylinder 422 will be gradually slid into the cylindrical groove 421 through the inclined surface 231, and the spring 423 will be compressed.

[0033] As a technical solution of the present invention, one end of one of the upper clamping blocks 21 is fixedly connected to an arc-shaped rack 211, which extends to another upper clamping block 21. An arc-shaped rack 222 is fixedly connected to the back of the other upper clamping block 21. The connection points of both the arc-shaped rack 211 and the arc-shaped rack 222 with the upper clamping block 21 are designed to be retractable, so that when the upper clamping blocks 21 on both sides slide up and down, the arc-shaped rack 211 and the arc-shaped rack... The locking teeth of the second gear 222 will not separate from the gear 223. The gear 223 is rotatably connected between the first arc-shaped rack 211 and the second arc-shaped rack 222 on the fixing block 3. One end of the gear 223 is fixedly connected to a fixing rod 224 of the same size as the circular groove 33. The fixing rod 224 is slidably connected in the circular groove 33. The end of the fixing rod 224 away from the gear 223 is fixedly connected to a flower gear 225. The flower gear 225 is slidably connected in the flower circular groove 34.

[0034] As a technical solution of the present invention, the adaptive component 4 includes an upper arc-shaped block 41 slidably connected to the arc-shaped groove 23 in the upper clamping block 21, one end of the upper arc-shaped block 41 being slidably connected to the fixed block 3, and a lower arc-shaped block 42 slidably connected to the arc-shaped groove 23 in the lower clamping block 22, the lower arc-shaped block 42 being fixedly connected to the fixed block 3.

[0035] As a technical solution of the present invention, a cylindrical groove 421 is provided on one side of the upper arc-shaped block 41 and the lower arc-shaped block 42. 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. A drive motor is provided at one end of both the cylinder 422 and the massage head 25. 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 provides a soothing massage to the scar area of ​​the patient's arm through the soft touch of the silicone material, promoting blood circulation and tissue repair. The silicone material at the end of the cylinder 422 simultaneously contacts the skin, assisting in the massage and enhancing the elastic pressure effect.

[0036] As a technical solution of the present invention, the hand training component 5 includes a fitting piece 51 fixedly connected to one end of the fixing block 3 away from the upper clamping block 21. A transition piece 52 is fixedly connected between the metacarpophalangeal joint and the first finger joint of the fitting piece 51. The fitting piece 51 is made of medical-grade TUP material, which has high biocompatibility, long-lasting elasticity, breathability, and waterproofness, making it suitable for long-term skin contact and reducing patient discomfort. Velcro 53 is fixedly connected to both sides of the finger portion and the palm portion of the fitting piece 51 to facilitate fitting different patient palm widths and finger sizes. Furthermore, a micro-massage head is provided inside the fitting piece 51. The micro massage head inside the adhesive patch 51 can provide targeted massage to the patient's hand, further relieving hand scars and muscle fatigue. The end of the arc-shaped block 35 away from the fixed block 3 is rotatably connected to a rotating plate 54. One end of the rotating plate 54 is located at the top of the metacarpophalangeal joint of the adhesive patch 51, and the other end of the rotating plate 54 is fixedly connected to a transition piece 52 in the middle of the adhesive patch 51. When the patient clenches their fist, the metacarpophalangeal joint pushes the rotating plate 54 to rotate. The rotating plate 54 relaxes and causes the transition piece 52 to move down, thereby relaxing the adhesive patches 51 at both ends of the first finger joint, thus relieving the tightness when the patient clenches their fist and reducing the friction of the adhesive patch 51 on the patient's injured area.

[0037] Working principle:

[0038] like Figures 1-2 and Figures 3-5 As shown, the user adjusts the position between the upper clamping block 21 and the lower clamping block 22 according to the width of their arm. First, the upper arc-shaped block 41 is slid downward in the square groove, so that it clamps the upper and lower parts of the arm with the upper arc-shaped block 41 and the lower arc-shaped block 42. Then, the gear 223 is pulled outward, causing the flower gear 225 to slide out of the flower-shaped groove 34. Then, the upper clamping block 21 and the lower clamping block 22, which are equipped with an arc-shaped rack 211 on one side, are pulled to one side. The arc-shaped rack 211 drives the gear 223 to rotate, and the gear 223 drives the arc-shaped rack 211 to rotate. Slide strip 222 to the other side, causing the upper clamping block 21 and lower clamping block 22 on the other side to move synchronously, so that the upper clamping blocks 21 and lower clamping blocks 22 on both sides move away from each other, so that they completely wrap around the arm. Then push gear 223 inward, so that the flower gear 225 is locked into the flower groove 34 again, limiting the upper clamping blocks 21 and lower clamping blocks 22 on both sides. At the same time, the cylinder 422 and spring 423 are no longer restricted by the arc groove 23 and slide out to the end away from the cylindrical groove 421, so that they are in complete contact with the patient's skin.

[0039] If the patient's arm is small, the patient will bring the upper clamping block 21 and lower clamping block 22 on both sides closer to each other, and the cylinder 422 will contact the inclined surface 231 at one end of the arc groove 23. The cylinder 422 will be slid into the cylindrical groove 421 through the inclined surface 231 and the spring 423 will be compressed.

[0040] like Figures 1-3 As shown, the patient's hand is then attached to the adhesive patch 51 using Velcro 53. The motor and micro motor are then activated to drive the massage head 25 to massage the patient's arm. The soft touch of the silicone material provides a soothing massage to the scar area of ​​the patient's arm, promoting blood circulation and tissue repair. The silicone material at the end of the cylinder 422 simultaneously contacts the skin, assisting in the massage and enhancing the elastic pressure effect. During prolonged treatment, the patient may experience numbness in their hand. When they want to clench their fist to relieve the numbness, their metacarpophalangeal joints touch one end of the rotating plate 54 during the clenching process and push it upward. At this time, the other end of the rotating plate 54 rotates towards the fingers and relaxes the traction on the transition plate 52. After the transition plate 52 relaxes, the pressure on the adhesive patches 51 at both ends of the first finger joint decreases, relieving the tightness when clenching the fist and reducing friction between the adhesive patch 51 and the scar area, thus improving training comfort.
