Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable ankle joint blood flow restriction rehabilitation training device. Background Technology
[0002] Ankle blood flow restriction rehabilitation training is an innovative rehabilitation method that combines low-intensity exercise with blood flow restriction techniques. This training method primarily targets the recovery of muscle strength and fitness, and is particularly suitable for the rehabilitation process after sports injuries. By restricting blood flow to the ankle and reducing oxygen supply, it induces a physiological response in the muscles under low-intensity exercise similar to that of high-intensity training. This method effectively stimulates muscle growth and strength improvement. To implement this training method, specialized ankle training equipment is required.
[0003] Some existing ankle rehabilitation devices can only apply constant pressure and cannot be dynamically adjusted according to the patient's specific condition. Furthermore, ankle rehabilitation devices are prone to slipping or tilting during use, which weakens the training effect and increases the risk of injury. Therefore, to address these issues, an adjustable ankle blood flow restriction rehabilitation training device is proposed. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an adjustable ankle joint blood flow restriction rehabilitation training device, which aims to improve the problem that some existing ankle joint training devices can only provide fixed pressure and are prone to sliding or tilting, thus limiting their applicability and effectiveness.

[0007] As a further description of the above technical solution:
[0008] The fixing component includes four corner blocks, which are externally fixedly connected to the four corners of the base. A guide cylinder is fixedly connected to the middle of each corner block. The guide cylinder has through slots on both its front and rear sides. A connecting shaft is slidably connected to the middle of the guide cylinder. Sliding rollers are fixedly connected to the front and rear sides of the connecting shaft. A pull handle is slidably connected to the outside of the guide cylinder. The pull handle has locking holes on both its front and rear sides. A short side base is fixedly connected to the bottom of the connecting shaft. A helical spring is fixedly connected to the top of the short side base. A rubber cup-shaped block is fixedly connected to the bottom of each corner block.
[0009] As a further description of the above technical solution:
[0010] The inner wall of the middle part of the half gear disk is rotatably connected to the outside of the connecting roller, and the rear side of the half gear disk is rotatably connected to the front side of the protective shell.
[0011] As a further description of the above technical solution:
[0012] The rear side of the half-gear disk contacts the front side of the telescopic control button, and the rear side of the half-gear disk is slidably connected to the front side of the vent.
[0013] As a further description of the above technical solution:
[0014] The rear side of the half gear disk is slidably connected to the front side of the air pump, and the external teeth of the motor gear are meshed with the external teeth of the half gear disk.
[0015] As a further description of the above technical solution:
[0016] The outer side of the sliding roller is slidably connected to the inner wall of the through groove, and the outer side of the sliding roller is slidably connected to the inner wall of the slot.
[0017] As a further description of the above technical solution:
[0018] The external sliding connection of the coupling is made to the middle of the top of the rubber cup-shaped block;
[0019] As a further description of the above technical solution:
[0020] The top end of the helical spring is fixedly connected to the inner top end of the rubber cup-shaped block, and the bottom end of the rubber cup-shaped block is in contact with the outer edge of the top end of the short side base.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, by starting the motor gear meshing with the half gear disk to rotate, the half gear disk squeezes the telescopic control button to retract, thereby controlling the start of the air pump to inflate the airbag plate. In conjunction with the external controller, the motor gear is started, allowing the motor gear to mesh with the half gear disk to rotate 90 degrees, thereby overlapping the port and the connecting shaft to achieve automatic inflation and deflation. This adjusts the pressure of the airbag plate on the patient's leg, restricts blood flow to the patient's ankle joint and surrounding muscles, and creates low-oxygen-strengthening muscles in the patient's foot and ankle joint, effectively enhancing the training effect.
[0023] 2. In this utility model, by turning the handle, the handle pulls the connecting shaft through the sliding roller, causing the connecting shaft to slide upward on the guide cylinder. At this time, the short side base plate fixed at the bottom of the connecting shaft will squeeze the spiral spring back, eventually forming a cone shape. The rubber cup-shaped block deforms and squeezes against the short side base plate, making the spiral spring and the ground form a small seal. The pressure in this space is less than the external pressure, thereby generating an adsorption force. This allows the device to be effectively fixed to the ground or other training surfaces by turning the fixed suction cup, preventing the device from sliding or tilting during use.

[0032] 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.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an adjustable ankle joint blood flow restriction rehabilitation training device, including a base 1, which serves as the foundation of the entire device and provides stability. A universal rod 2 is fixedly connected to the top center of the base 1. The universal rod 2 allows for multi-angle movement up, down, and sideways via a rotating ball in the center. The design of the universal rod 2 ensures the user's freedom of movement during foot training. A support plate 3 is fixedly connected to the top of the universal rod 2. Pedals 4 are fixedly connected to the left and right sides of the top of the support plate 3. The pedals 4 assist the patient's foot movement. An airbag plate 5 is fixedly connected to the rear of the top of the pedal 4. The airbag plate 5 is in an inflatable state, allowing the patient's lower leg to pass through it.
[0034] refer to Figure 3 , Figure 4 A protective shell 6 is fixedly connected to the front interior of the airbag plate 5. An air pump 7 is fixedly connected to the right side of the interior of the protective shell 6. The air pump 7 inflates the airbag plate 5 through the protective shell 6. A vent 8 is provided on the left side of the protective shell 6 to allow the airbag plate 5 to deflate. A connecting roller 9 is fixedly connected to the middle of the protective shell 6. A telescopic control button 10 is provided at the front right end of the protective shell 6. The telescopic control button 10 is electrically connected to the air pump 7 and can control the start of the air pump 7.
[0035] A protective cover 11 is fixedly connected to the outside of the protective shell 6. A motor gear 12 is located on the right side of the protective cover 11. The motor gear 12 is a combination of a motor and a drive gear, and the motor drives the drive gear to rotate. A half-gear disk 13 is rotatably connected inside the protective cover 11. A semi-circular rack is located on the right side of the half-gear disk 13, and the two ends of the rack are higher than the teeth in the middle, thus limiting the rotation of the gear disk to ninety degrees. The inner wall of the middle part of the half-gear disk 13 is rotatably connected to the outside of the connecting roller 9, and the connecting roller 9 limits the rotation position of the half-gear disk 13.
[0036] The rear side of the half-gear disk 13 is rotatably connected to the front side of the protective shell 6. The rear side of the half-gear disk 13 contacts the front side of the telescopic control button 10. The half-gear disk 13 is confined to a fixed position by the protective shell 6 and rotates. After the half-gear disk 13 rotates, it will squeeze and retract the telescopic control button 10, allowing the telescopic control button 10 to open and control the air pump 7 to start. The rear side of the half-gear disk 13 is slidably connected to the front side of the vent 8 and the air pump 7 to prevent gas leakage. The external teeth of the motor gear 12 are meshed with the external teeth of the half-gear disk 13, and the motor gear 12 drives the half-gear disk 13 to rotate. The bottom front end of the half-gear disk 13 has an opening 14, which is the same size as the vent 8.
[0037] refer to Figure 5 , Figure 6 The four outer corners of the base 1 are fixedly connected to fixing components. The fixing components include four corner blocks 15. The four corner blocks 15 are fixedly connected to the four outer corners of the base 1. The center of the corner block 15 is fixedly connected to the guide tube 16. The corner block 15 positions the guide tube 16 and fixes it.
[0038] The guide cylinder 16 has through grooves 17 on both its front and rear sides. These grooves are elongated and have a certain sliding space. A connecting shaft 18 is slidably connected to the middle of the guide cylinder 16. Sliding rollers 19 are fixedly connected to both the front and rear sides of the middle of the connecting shaft 18. The outer side of the sliding rollers 19 is slidably connected to the inner wall of the through groove 17. When the sliding rollers 19 slide in the through groove 17, they drive the connecting shaft 18 to slide up and down.
[0039] The guide cylinder 16 is slidably connected to a pull handle 20. The pull handle 20 has locking holes 21 on both the front and rear sides. The slide roller 19 is slidably connected to the inner wall of the locking holes 21. The bottom end of the connecting shaft 18 is fixedly connected to a short side base 22. The top end of the short side base 22 is fixedly connected to a helical spring 23. The helical spring 23 provides the necessary rebound force to support the movement of the bottom side and also has a certain buffering effect. It is made of high-strength material to ensure the durability of its elasticity.
[0040] A rubber cup-shaped block 24 is fixedly connected to the bottom end of corner block 15, supporting the rubber cup-shaped block 24. The top end of the coil spring 23 is fixedly connected to the inner top end of the rubber cup-shaped block 24, and the outer side of the connecting shaft 18 is slidably connected to the middle of the top end of the rubber cup-shaped block 24. The lower part of the inner wall of the rubber cup-shaped block 24, where it connects with the coil spring 23, provides stable contact and support. The bottom end of the rubber cup-shaped block 24 contacts the outer edge of the top end of the short side base 22, and pressure is generated when the rubber cup-shaped block 24 and the short side base 22 are pressed together.
[0041] Working principle: The user moves the device to a suitable position, and then pulls the handles 20 defined by the four corners of the corner block 15 downwards until the bottom tip of the handle 20 is engaged with the top of the corner block 15, and the sliding roller 19 and the locking hole 21 are inclined inwards, thus completing the fixation of the device.
[0042] During the rotation of the handle 20, the corner block 15 presses down and deforms the rubber cup-shaped block 24. The handle 20 then pulls the connecting shaft 18 upward via the sliding roller 19. The short side base 22 at the top of the connecting shaft 18 deforms upward and compresses the coil spring 23 until the coil spring 23 curls into a disc shape. This achieves a tight fit between the outer edge of the short side base 22 and the bottom outer edge of the coil spring 23, creating a small seal between the coil spring 23 and the ground. The pressure in this space is less than the external pressure, thus generating an adhesive force. This helps the user to fix the device in place and prevents it from moving during use.
[0043] Once the device is in place, the patient can place their foot inside the airbag plate 5. Then, through an external controller, the motor gear 12 engages with the half-gear disk 13 to rotate. The half-gear disk 13 compresses the telescopic control button 10 to retract, thereby controlling the air pump 7 to start, so as to inflate the airbag plate 5 and apply pressure to the patient's lower leg. Under continuous pressure, the local muscles of the patient's lower leg are stimulated due to hypoxia, prompting the body to adapt to this low-oxygen state. At this time, the patient can also use the multi-angle rotation characteristics of the universal rod 2 to swing their foot back and forth and left and right, so that the foot can still activate muscle growth and enhance strength under relatively low load.
[0044] During training, the controller can intermittently give the motor gear 12 a command to rotate, causing the motor gear 12 to mesh with the half gear disk 13 and rotate 90 degrees. This allows the port 14 and the connecting shaft 18 to overlap and release air from the airbag plate 5, thus adjusting the tightness of the airbag plate 5 and ensuring that the patient's lower leg is not subjected to excessive pressure for too long.
[0045] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
