Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an exercise device for preventing thrombosis. Background Technology

[0002] Thrombosis prevention exercise devices are a type of medical equipment designed to prevent thrombosis. Common types include air pressure wave therapy devices, lower limb active and passive movement rehabilitation devices, and intelligent ankle balance trainers. Air pressure wave therapy devices use a main unit, inflatable tubing, and pressurized airbags to repeatedly inflate and deflate the limbs, promoting blood and lymphatic flow. Lower limb active and passive movement rehabilitation devices target the joints of the lower limbs with active and passive movements, increasing the velocity of deep vein blood flow. Intelligent ankle balance trainers utilize sensor-operated pedals and muscle electromyography (EMG) signal acquisition modules to precisely control training parameters and improve ankle function. All these devices promote blood circulation, preventing deep vein thrombosis caused by blood stasis and reducing the risk of related diseases. They also have certain preventive and therapeutic effects on limb edema and muscle atrophy.

[0003] Thrombosis prevention exercise devices primarily function by promoting blood circulation. Lower limb active and passive movement rehabilitation devices use motors to drive or assist patients in active and passive movements of the hip, knee, and ankle joints, stretching muscles, compressing blood vessels, activating muscle pumps, and increasing deep vein blood flow velocity in the lower limbs. Intelligent ankle balance trainers use sensory pedals to detect foot status, and a muscle electromyography (EMG) module collects calf muscle EMG signals. Based on this data, a microprocessor in the main unit uses specific algorithms to control joint axis movement, precisely adjusting training parameters to promote ankle joint function recovery and ensure normal lower limb blood circulation.

[0004] However, some existing thrombosis prevention exercise devices suffer from instability during use. Although the structure of these devices is complex, it is not stable enough when fixing the patient's lower limb joints. Faced with different limb shapes and the forces generated during movement, the fixing parts are prone to displacement, making it impossible to accurately maintain the correct position of the lower limb during exercise training. This significantly reduces the effectiveness of stretching muscles, compressing blood vessels, activating muscle pumps, and increasing the blood flow velocity in the deep veins of the lower limbs, seriously affecting the effectiveness of promoting ankle joint function recovery and ensuring normal blood circulation in the lower limbs. Therefore, a thrombosis prevention exercise device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a thrombosis prevention exercise device, which aims to improve the problem of instability in the use of existing thrombosis prevention exercise devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a thrombosis prevention exercise device, comprising a base plate, with support rods fixedly connected to the front and rear sides of the base plate respectively, slide rods slidably connected inside the two support rods, nuts threadedly connected to the right sides of the two slide rods respectively, rotating shafts rotatably connected to the left sides of the two slide rods respectively, support rods fixedly connected to adjacent sides of the two rotating shafts respectively, two slide rails fixedly connected to adjacent sides of the two support rods respectively, multiple sliders slidably connected inside the two slide rails respectively, connecting pads fixedly connected to the right sides of the multiple sliders, telescopic rods fixedly connected to the right sides of the connecting pads, clamping chambers fixedly connected to the right sides of the telescopic rods, anti-slip pads fixedly connected inside the clamping chambers, nuts threadedly connected to the front and rear sides of the clamping chambers respectively, and a fixing component for fixing the feet fixedly connected to the top of the base plate.

[0007] As a further description of the above technical solution: the fixing component includes a functional rod one, the bottom end of which is fixedly connected to the top end of the base plate. Two functional rods two are fixedly connected to the top end of the base plate. Moving blocks one are slidably connected to the inner walls of the two functional rods two respectively. Two moving blocks two are slidably connected to the front and rear inner walls of the functional rod one. Connecting strips are rotatably connected to the opposite sides of the two moving blocks two respectively. Connecting rods are fixedly connected to the opposite sides of the two connecting strips respectively. Connecting rings are rotatably connected to the middle of the connecting rods. Connecting plates are fixedly connected to the top end of the connecting rings. A vent pipe one is fixedly connected inside the connecting plate. An air cushion one is fixedly connected to the top end of the connecting plate. A contact plate is fixedly connected to the top end of the air cushion one.

[0008] As a further description of the above technical solution: two outer plates are fixedly connected to the top of the contact plate, and air cushions are fixedly connected to the adjacent sides of the two outer plates respectively.

[0009] As a further description of the above technical solution: the two air cushions are respectively fixedly connected to the opposite sides of each other with a vent pipe, and the top of each of the two outer plates is respectively fixedly connected to a top cover.

[0010] As a further description of the above technical solution: a plurality of air cushions III are fixedly connected to the top of the contact plate, and a top cover II is fixedly connected to the top of the plurality of air cushions III.

[0011] As a further description of the above technical solution: the bottom ends of the plurality of movable blocks two are fixedly connected to retractable rods, and the exterior of the vent pipe one is fixedly connected to the interior of the air cushion one.

[0012] As a further description of the above technical solution: the external part of the second vent pipe is fixedly connected to the inside of the outer plate, and the top end of the second air cushion is fixedly connected to the bottom end of the top cover.

[0013] As a further description of the above technical solution: the internal threads of the multiple nuts II on their adjacent sides are connected to the inside of the anti-slip pad, and the external threads of the two nuts I are connected to the inside of the two support rods I.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, rotating nut one causes the slide rod to slide within support rod one, which in turn moves support rod two via a rotating shaft, adjusting the positions of the two slide rails. The change in the slide rail positions causes the slider to slide within it, which in turn moves the connecting pad, telescopic rod, and clamping chamber. When the clamping chamber is aligned with the chair leg, rotating nut two secures the clamping chamber to the chair leg. At this point, the clamping chamber causes the anti-slip pad to fit tightly against the chair leg, thus achieving a stable connection between the device and the chair, forming a unified whole and providing stable support for subsequent exercise.

[0016] 2. In this invention, the sliding of movable block one within functional rod two adjusts the position of its associated structure. Movable block two slides along the inner wall of functional rod one, rotating the connecting rod via a connecting strip, which in turn moves the connecting ring and the connecting plate above it. When air cushion one, air cushion two, and air cushion three are inflated, the gas pushes them to expand, causing the contact plate, outer plate, top cover one, and top cover two to move. Through this structural operation, the air cushions automatically adjust to the shape and position of the foot, perfectly conforming to the foot and providing comfortable and stable support for the user.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 3 This utility model provides an embodiment of a thrombosis prevention exercise device, comprising a base plate 1, with support rods 2 fixedly connected to the front and rear sides of the base plate 1 respectively. Sliding rods 3 are slidably connected inside each of the two support rods 2. The position of the sliding rods 3 can be flexibly changed according to the actual usage scenario and different chair sizes, thereby adapting to chair legs with different spacing and enhancing the versatility of the device. Nuts 4 are threadedly connected to the right side of each of the two sliding rods 3. After the sliding rod 3 is adjusted to a suitable position, tightening the nuts 4 firmly fixes the sliding rod 3 inside the support rods 2, preventing accidental sliding during use and ensuring the stability of the overall structure of the device.

[0025] The left side of each of the two sliding rods 3 is rotatably connected to a pivot 5, allowing subsequent structures connected to the pivot 5 to flexibly change their angle in the horizontal direction. This better adapts to different tilt angles of the chair legs, improving the flexibility and adaptability of the connection between the device and the chair. Support rods 6 are fixedly connected to adjacent sides of the two pivots 5, combining the linear adjustment of the sliding rods 3 with the angular adjustment of the support rods 6. This further optimizes the device's adaptability to different chair leg positions and angles, allowing the device to fit the chair legs more tightly and securely. Two slide rails 7 are fixedly connected to adjacent sides of the two support rods 6. When the support rods 6 are adjusted to the correct angle, the slide rails 7 are also positioned accordingly. The slide rails 7 work by using their smooth internal tracks to provide a smooth sliding path for the sliders 8. Multiple sliders 8 are slidably connected inside the two slide rails 7, greatly increasing the device's adaptability to chair legs of different sizes and enhancing its practicality.

[0026] Multiple sliders 8 are fixedly connected to the right side with connecting pads 9, ensuring the stability of the telescopic rod 10 installation and providing cushioning and fine-tuning of the angle during the entire movement of the device, thus improving the device's durability and user comfort. The telescopic rod 10 is fixedly connected to the right side of the connecting pads 9, allowing it to flexibly adjust its length according to the actual distance between the chair leg and the device body, ensuring that the clamping chamber 11 can accurately hold the chair leg, further enhancing the device's adaptability to different chairs. The clamping chamber 11 is fixedly connected to the right side of the telescopic rod 10, and the clamping chamber 11 is used to directly clamp the chair leg.

[0027] The clamping compartment 11 is typically designed with a specific opening shape and size to effectively enclose the chair legs. An anti-slip pad 13 is fixedly connected inside the clamping compartment 11, and the anti-slip pad 13 contacts the surface of the chair legs when the clamping compartment 11 clamps the chair legs. Nuts 12 are threadedly connected to the front and rear sides of the clamping compartment 11, and rotating the nuts 12 generates an inward pressing force on the front and rear sides of the clamping compartment 11. A fixing component for securing the feet is fixedly connected to the top of the base plate 1.

[0028] Reference Figures 2 to 4 The fixing component includes a functional rod 14, the bottom end of which is fixedly connected to the top end of a base plate 1. Two functional rods 15 are fixedly connected to the top end of the base plate 1, transmitting external forces to the base plate 1 to maintain the stability of the entire structure. Its beneficial effect is that, working in conjunction with functional rod 14, it provides a stable installation and movement track for subsequent components such as movable blocks 16, allowing the fixing component to better adapt to different working requirements and improve the overall performance of the device. Movable blocks 16 are slidably connected to the inner walls of the two functional rods 15. Users can flexibly adjust the height of movable blocks 16 according to actual needs, thereby changing the position of other components connected to movable blocks 16 to adapt to chairs of different heights or usage scenarios, greatly enhancing the versatility and flexibility of the fixing component.

[0029] Two movable blocks 17 are slidably connected to the inner walls of the front and rear sides of functional rod 14. Similar to the sliding of movable block 16 within functional rod 15, relative movement is achieved through clearance fit. Movable blocks 17 can move along the front-rear direction on the inner wall of functional rod 14. Connecting bars 18 are rotatably connected to the far sides of the two movable blocks 17. When movable blocks 17 move on functional rod 14, the angle of the connecting bars 18 changes with the position of the movable blocks 17. Connecting rods 19 are fixedly connected to the far sides of the two connecting bars 18. The connecting rods 19 are connected to the connecting bars 18 through a fixed connection, ensuring that the movement of the connecting bars 18 is accurately transmitted to the connecting rods 19. During rotation, the connecting bars 18 cause the connecting rods 19 to move to different positions. A connecting ring 20 is rotatably connected to the middle of the connecting rods 19. When the position or angle of the connecting rods 19 changes, the connecting ring 20 can rotate flexibly on the connecting rods 19 to adapt to this change.

[0030] A connecting plate 21 is fixedly connected to the top of the connecting ring 20. When the connecting ring 20 rotates around the connecting rod 19 or moves with the connecting rod 19, the connecting plate 21 will change its position and angle accordingly. An air vent pipe 22 is fixedly connected inside the connecting plate 21, and an air cushion 24 is fixedly connected to the top of the connecting plate 21. A contact plate 23 is fixedly connected to the top of the air cushion 24. The elasticity and cushioning effect of the air cushion 24 can be transmitted to the contact plate 23. The contact plate 23 directly contacts the chair or the user's body. When the air cushion 24 is deformed under pressure, the contact plate 23 will adjust its fit to the contact area accordingly.

[0031] Reference Figures 1 to 3 Two outer plates 29 are fixedly connected to the top of the contact plate 23, and air cushions 26 are fixedly connected to the adjacent sides of the two outer plates 29. Air is filled inside the air cushions 26, giving them a certain degree of elasticity and compressibility. When the user's leg or other body part comes into contact with the air cushions 26, they will adaptively deform according to the contact pressure. Vent pipes 25 are fixedly connected to the distant sides of the two air cushions 26, allowing air to enter and exit the air cushions 26 through the vent pipes 25 when the air pressure needs to be adjusted. Top covers 28 are fixedly connected to the tops of the two outer plates 29. The top covers 28 protect the air cushions 26 below from interference and damage from external debris, and also contribute to aesthetics and overall integrity.

[0032] Multiple air cushions 27 are fixedly connected to the top of the contact plate 23. The arrangement of multiple air cushions 27 provides more comprehensive coverage of the top area of ​​the contact plate 23, offering users a wider range of cushioning and support. A top cover 30 is fixedly connected to the top of the multiple air cushions 27. The fixing method is similar to that of other components. The function of the top cover 30 is similar to that of the top cover 28, protecting the air cushions 27 below from external damage and preventing foreign objects from entering and affecting their performance. A retractable rod 31 is fixedly connected to the bottom of multiple movable blocks 17. When the movable blocks 17 slide on the inner wall of the functional rod 14, the retractable rod 31 changes position as the movable blocks 17 move. The vent pipe 22 is externally fixedly connected to the inside of the air cushion 24.

[0033] By securely fixing the exterior of the vent pipe 22 to the interior of the air cushion 24, a sealed gas channel is formed. When inflation or deflation of the air cushion 24 is required, gas enters and exits the air cushion 24 through the vent pipe 22. The exterior of the vent pipe 25 is fixedly connected to the interior of the outer plate 29. By reserving a suitable installation position inside the outer plate 29, the vent pipe 25 is fixed therein, ensuring a tight and stable connection with the air cushion 26. The top of the air cushion 26 is fixedly connected to the bottom of the top cover 28. The internal threads of multiple nuts 12 on adjacent sides are connected to the interior of the anti-slip pad 13. Based on the helical drive of the threads, axial force is generated by rotation, which tightens the nuts 12 and the anti-slip pad 13. This connection method allows the anti-slip pad 13 to better conform to the surface of the chair leg when the clamping chamber 11 clamps the chair leg, and the pressure distribution of the anti-slip pad 13 on the chair leg can be changed by adjusting the position of the nuts 12. The external threads of the two nuts 4 are connected to the inside of the two support rods 2. Using the helical drive of the threads, the position of the nuts 4 inside the support rods 2 is adjusted by rotating them. After the slide rod 3 has been adjusted to its extended length, rotating the nuts 4 will firmly fix the slide rod 3 inside the support rods 2.

[0034] Working Principle: During use, the support rods 2 fixed on the front and rear sides of the base plate 1 drive the internal slide rod 3 to slide. The slide rod 3 is fixed in position by the nut 4, and the rotating shaft 5 connected to its left side drives the support rod 6 to move. The support rod 6 drives the slide rail 7 fixed on one side, which in turn drives the internal slider 8 to slide. The slider 8 drives the right connecting pad 9, the telescopic rod 10, and the clamping compartment 11 to move. The clamping compartment 11 fixes the chair legs with the internal anti-slip pad 13 and the nuts 12 threaded on both sides. Through the coordinated movement of each component, the position of the clamping compartment is precisely adjusted and the chair legs are firmly fixed, thereby achieving a stable connection between the device and the chair into a whole, ensuring that the device can effectively assist the chair in performing its function.

[0035] In use, the functional rod 14 and two functional rods 15 fixed to the top of the base plate 1 drive the sliding blocks 16 on the inner wall of functional rod 15 and the sliding blocks 17 on the front and rear inner walls of functional rod 14 to slide. The sliding blocks 17 drive the connecting strip 18 rotatably connected to the opposite side to move. The connecting strip 18 drives the connecting rod 19. The connecting ring 20 rotatably connected in the middle of the connecting rod 19 drives the connecting plate 21 to move. The connecting plate 21 drives the internal vent pipe 22, the top air cushion 24, and the contact plate 23 to move. The contact plate 23 drives the two outer plates 29, multiple air cushions 27, and the top cover 30 to move. The outer plates 29 drive the air cushion 26 on the adjacent side, the top cover 28, and the vent pipe 25 on the opposite side to move. The multiple sliding blocks 17 also drive the retractable rod 31 at the bottom to move. Through the coordinated sliding and driving of each component, air cushion 1 24, air cushion 26 and air cushion 3 27 are inflated, thereby achieving flexible adjustment of the foot support angle, effectively adapting to the imperfect fit between different people's feet and the chair, and improving user comfort.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
