Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically an integrated inflatable pressure adjustable inner liner ankle brace. Background Technology

[0002] After the ligament of the distal tibiofibular syndesmosis is ruptured, the ankle mortise will widen, the ankle joint will become unstable, and the pressure on the tibiotalar joint will be uneven, which will lead to secondary ankle osteoarthritis, resulting in limited ankle joint function and seriously affecting the quality of life. At this time, it is necessary to use an ankle brace to support the patient's ankle joint, which will help patients with distal tibiofibular syndesmosis injury to move and repair early. Existing ankle braces consist of two types: one type has a soft inner material and a hard outer material, with the soft material contacting the skin and the hard material providing support; the other type has an air bladder inside and a splint outside, with the air bladder contacting the skin and the splint providing support. Existing ankle braces have the following problems: the former has limited deformation of soft materials when supporting the patient's ankle joint, and cannot maintain the stability of the distal tibiofibular syndesmosis at all times; the latter requires the use of specific tools to adjust the air pressure in the air bladder if the pressure on the distal tibiofibular syndesmosis needs to be adjusted, which is cumbersome. Therefore, we propose an integrated inflatable pressure adjustable liner ankle brace. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an integrated inflatable pressure adjustable inner liner ankle brace.

[0015] Please see Figure 1-6 This embodiment provides a technical solution: an integrated inflatable pressure adjustable liner ankle brace, including a shaped outer splint 1, an integrated shaped airbag 2 inside the shaped outer splint 1, and an adjustment mechanism 3. The integrated shaped airbag 2 has a nylon liner 4 inside. The left end of the shaped outer splint 1 has evenly distributed male hook and loop fasteners 6 and female hook and loop fasteners 7 on its front and rear sides, respectively. The right side of the male hook and loop fastener 6 is fitted to the left side of the longitudinally adjacent female hook and loop fastener 7. The right end of the shaped outer splint 1 has evenly distributed elastic bands 5. (The elastic band 5 is an elastic nylon band). The bottommost elastic band 5 is inclined. The staff opens the male hook and loop fastener 6 and the female hook and loop fastener 7, and then puts the shaping outer splint 1 on the patient's foot so that the nylon liner 4 comes into contact with the patient's skin to avoid friction or pressure damage to the skin. Then the right side of the male hook and loop fastener 6 comes into contact with the left side of the female hook and loop fastener 7, so that the bristles on the right side of the male hook and loop fastener 6 and the fibers on the left side of the female hook and loop fastener 7 are tightly interlocked, thereby fixing the shaping outer splint 1 to the patient's foot. Adjustment mechanism 3 includes a fixed base 31, a clearance groove 32, a sliding column 33, a baffle 34, an air inlet 35, and an air inlet pipe 36. The fixed base 31 is located at the air inlet on the front side of the integrated shaping airbag 2. A clearance groove 32 is provided inside the fixed base 31, and a sliding column 33 is slidably connected inside the clearance groove 32. A baffle 34 is provided at the rear end of the sliding column 33, passing through the rear wall of the fixed base 31. Evenly distributed air inlets 35 are provided on the rear side of the fixed base 31. The fixed base 31 is connected to the integrated shaping airbag 2 through the air inlets 35. An air inlet pipe 36 is provided at the opening on the right side of the outer surface of the fixed base 31. The adjustment mechanism 3 also includes a push... The adjustment mechanism 3 also includes a plate 37 and a protective cover 38. The front end of the sliding column 33 passes through the front wall of the fixed base 31 and is provided with a push plate 37. The front side of the fixed base 31 is provided with a protective cover 38. The push plate 37 is located inside the protective cover 38. The adjustment mechanism 3 also includes a reset assembly 39, which includes a limit ring 391 and a spring 392. The limit ring 391 is fixedly sleeved on the front side of the outer surface of the sliding column 33, and the spring 392 is movably sleeved on the rear side of the outer surface of the sliding column 33. The spring 392 is located between the rear side of the limit ring 391 and the rear wall of the clearance groove 32. The reset assembly 39 also includes a rib 393 and a rib groove 394. The outer surface of the limit ring 391 is provided with a uniformly distributed... The fabric ribs 393 and the sidewalls of the clearance grooves 32 are provided with evenly distributed rib grooves 394. The ribs 393 are all slidably connected to the interior of adjacent rib grooves 394. Then, an external air pump is connected to the fixed base 31 through the air inlet pipe 36. Then, the push plate 37 is pressed. Under the restriction of the ribs 393 and rib grooves 394, the push plate 37 drives the baffle 34 to move through the sliding column 33, so that the air inlet 35 is opened. At this time, the limiting ring 391 slides in the clearance groove 32 to compress the spring 392. Then, the external air pump can inflate the shaping integrated airbag 2. After adjusting to a suitable pressure, the push plate 37 is released, and the spring 392 drives the spring through the rebound force. The limiting ring 391 moves, and the movement of the limiting ring 391 drives the baffle 34 to return to its original position through the sliding column 33, closing the air inlet 35. Due to the presence of the protective cover 38, external pressure is prevented from causing the air inlet 35 to open involuntarily. After the adjustable inflation pressure inner liner ankle brace has been used for a period of time, when the pressure is too low, repeat the inflation operation, that is, press the push plate 37 to inflate through an external air pump to increase the pressure. When the pressure is too high, press the push plate 37 to open the air inlet 35, and the gas flows out through the air inlet 35 to reduce the pressure. The operation is simple, and the shaping integrated airbag 2 always fits the skin, which can always maintain the stability of the tibiofibular syndesmosis.

[0016] The working principle of the integrated inflatable pressure adjustable liner ankle brace provided by this utility model is as follows: The operator opens the male hook and loop fastener 6 and the female hook and loop fastener 7, and then puts the molded outer splint 1 on the patient's foot, so that the nylon liner 4 comes into contact with the patient's skin to avoid friction or pressure damage to the skin. Then, the right side of the male hook and loop fastener 6 comes into contact with the left side of the female hook and loop fastener 7, so that the bristles on the right side of the male hook and loop fastener 6 and the fibers on the left side of the female hook and loop fastener 7 are tightly engaged, thereby fixing the molded outer splint 1 to the patient's foot. Then, the external air pump is connected to the fixing seat 31 through the air inlet pipe 36. Then, the push plate 37 is pressed. Under the restriction of the ribs 393 and the rib grooves 394, the push plate 37 drives the baffle 34 to move through the sliding column 33, so that the air inlet 35 is opened. At this time, the limiting ring 391 is in the avoidance groove 3. The inner sliding compression spring 392 is used to inflate the shaping airbag 2 via an external air pump. After adjusting to a suitable pressure, the push plate 37 is released, and the spring 392 moves the limiting ring 391 through its rebound force. The movement of the limiting ring 391 drives the baffle 34 to return to its original position via the sliding column 33, closing the air inlet 35. Due to the presence of the protective cover 38, external pressure is prevented from causing the air inlet 35 to open involuntarily. After the adjustable inflation pressure inner lining ankle brace has been used for a period of time, when the pressure is too low, the inflation operation is repeated, that is, the push plate 37 is pressed to inflate the airbag via an external air pump to increase the pressure. When the pressure is too high, the push plate 37 is pressed to open the air inlet 35, and the gas flows out through the air inlet 35 to reduce the pressure. The operation is simple, and the shaping airbag 2 always fits in close contact with the skin, which can always maintain the stability of the tibiofibular syndesmosis.
