And, without creative efforts, the technical means or technical features in the embodiments of the present invention can be replaced. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] As Figure 1As shown, a thrombus prevention device with dual functions of exercise and air pressure includes a host 1, an ankle joint trainer 2 and at least one air pressure sleeve 3. The ankle joint trainer 2 is electrically connected to the output port of the host 1, and at least one air pressure sleeve 3 is connected to the air supply port of the host 1 through an air tube. The air pressure sleeve 3 uses an air pressure foot sleeve and / or air pressure glove. The air pressure sleeve 3 intermittently pressurizes the foot and / or hand.

[0025] The host 1 also includes a battery pack and a battery charging protection control board. The battery pack is connected to the battery charging protection control board. The battery charging protection control board and the switching power supply are connected to the CPU control board through a switch to supply power to the host.

[0026] The main unit 1 also includes a high-pressure gas chamber, a gas supply solenoid valve and a deflation solenoid valve. The gas output port of the 24V air pump is connected to the air inlet of the high-pressure gas chamber, the air outlet of the high-pressure gas chamber is connected to one end of the gas supply solenoid valve, the other end of the gas supply solenoid valve is connected to the air inlet of the air pressure sleeve through an air pipe to supply air to the air pressure sleeve, and the air outlet of the air pressure sleeve is connected to one end of the deflation solenoid valve through an air pipe.

[0027] like Figure 3 and Figure 4 As shown, the ankle joint trainer 2 comprises a trainer housing 4, a movable foot plate 5, a movable foot plate driving mechanism and a leg support plate 6. The leg support plate 6 is fixed to the upper side of the trainer housing 4. The movable foot plate 5 is hinged to the upper side of the trainer housing 4 and connected to the movable foot plate driving mechanism and driven by the movable foot plate driving mechanism to rotate along the hinge axis. The movable foot plate 5 and the leg support plate 6 are arranged on the same straight line, and the distance between the movable foot plate 5 and the leg support plate 6 matches the distance between the foot and the calf of the human body.

[0028] The movable footplate driving mechanism includes a slider 7, a swing arm 8, a guide rail 9, a nut 10, a screw rod 11, a screw rod bracket 12, a first pulley 13, a second pulley 14, a synchronous belt 15 and a driving motor 16. The guide rail 9 is arranged perpendicular to the hinge axis direction of the movable footplate 5 and fixed inside the trainer housing 4, that is, the guide rail 9 is arranged along the length direction of the entire ankle trainer. The slider 7 is slidably arranged on the guide rail 9 and can slide back and forth along the length direction of the guide rail 9. Since the slider 7 only needs to drive the movable footplate 5 to rotate back and forth along the hinge axis, the required stroke length of the slider 7 is not long, that is, the required length of the guide rail 9 is relatively short. However, the movable footplate 5 needs to occupy a large space, so components such as motors cannot be installed in the housing at its bottom. Therefore, the position of the guide rail 9 is far from the movable footplate 5, so the slider 7 adopts a long strip structure and extends below the movable footplate 5. One end of the swing arm 8 is hinged to the slider 7, and the other end of the swing arm 8 is hinged to the movable footplate 5. The screw rod 11 is arranged parallel to the guide rail 9 on one side of the guide rail 9, and both ends of the screw rod 11 are rotatably arranged on the screw rod brackets 12 on both sides. The nut 10 is sleeved on the screw rod 11 and threadedly connected to the screw rod 11. The nut 10 is fixedly connected to the slider 7. The first pulley 13 is fixed to one end of the screw rod 11, the second pulley 14 is fixed to the output shaft of the driving motor 16, and the synchronous belt 15 is arranged on the first pulley 13 and the second pulley 14. When working, the driving motor 16 drives the second pulley 14 to rotate, the second pulley 14 drives the first pulley 13 to rotate synchronously through the synchronous belt 15, the first pulley 13 drives the screw rod 11 to rotate, so as to drive the nut 10 to move on the screw rod 11, the nut 10 drives the slider 7 to slide on the guide rail 9, and the slider 7 drives the movable footplate 5 to rotate along the hinge axis through the swing arm 8. A speed sensor is also installed on the output shaft of the driving motor 16, and the rotation speed of the driving motor 16 is collected in real time through the speed sensor to cooperate with the motor drive module 18 to control the driving motor 16. A power interface is provided on the trainer housing 4 for connecting an external power supply. The power interface is connected to the motor drive module 18 to supply power to the motor drive module 18, and the motor drive module 18 is connected to the driving motor 16 to control the operation of the driving motor 16. An emergency stop button 17 is also provided on the trainer housing 4 for controlling the emergency stop of the ankle trainer. In this embodiment, the motor drive module 18 adopts a conventional type of motor drive module such as L298N, TB6612FNG or DRV8833.

[0029] The movable footplate 5 includes a sole flat plate 19, a heel arc-shaped enclosing plate 20 and an external bracket 21. The heel arc-shaped enclosing plate 20 is arranged perpendicular to the sole flat plate 19, and one side edge of the heel arc-shaped enclosing plate 20 is fixedly connected to one end edge of the sole flat plate 19 to form a bucket-shaped heel supporting structure. The external bracket 21 is fixed on the outer side of the heel arc-shaped enclosing plate 20. Hinge shaft structures protruding and extending outward are arranged on both sides of the external bracket 21, and both sides of the external bracket 21 are hinged to the trainer housing 4 through the hinge shaft structures. When in use, the heel is placed in the bucket-shaped heel supporting structure formed by the heel arc-shaped enclosing plate 20 and the sole flat plate 19, and then under the drive of the drive motor 16, the movable footplate 5 rotates back and forth, thereby promoting the plantar flexion and dorsiflexion movements of the ankle joint. The swing arm 8 is hinged to the external bracket 21 in the movable footplate 5. Since the external bracket 21 is located on the outer side of the heel arc-shaped enclosing plate 20, that is, on the outer side of the heel position of the movable footplate 5. Binding strap perforations 22 are formed on the sole flat plate 19 and the heel arc-shaped enclosing plate 20. The leg support plate 6 is of an overall U-shaped structure. The leg support plate 6 adopts a variable diameter structure matching the shape of the human calf along the length direction of the leg support plate 6. Binding strap perforations 22 are formed on both side edges of the leg support plate 6. Binding straps are arranged in the binding strap perforations 22, and the binding straps are elastic magic tape straps. When the heel is placed on the movable footplate 5 and the calf is placed on the leg support plate 6, they are respectively fixed by the elastic magic tape straps, so that the ankle can follow the rotation of the movable footplate 5 to perform plantar flexion and dorsiflexion movements. Heat dissipation holes 23 are formed on both sides of the bottom of the trainer housing 4. When the drive motor 16 works, heat will be generated, and the heat generated by the drive motor 16 can be dissipated through the heat dissipation holes 23.

[0030] As Figure 5 and Figure 6 shown, the pneumatic foot sleeve and the pneumatic glove include a sleeve body 24 and an airbag 25. The airbag 25 is arranged in the sleeve body 24, and elastic magic tape straps are arranged on the sleeve body 24.

[0031] The working principle of a thrombus prevention device combining the dual functions of exercise and air pressure of the present invention is as follows: First, connect the ankle trainer 2 and the air pressure sleeve 3 to the host 1. The user places the heel on the bucket-shaped heel support structure formed by the heel arc-shaped apron 17 and the sole flat plate 16, then places the calf on the leg support plate 3, and then fixes the foot and calf in the movable foot plate 2 and the leg support plate 3 respectively through elastic magic tape straps. At the same time, the air pressure foot sleeve and / or the air pressure glove are sleeved on the user's foot or hand. The 24V air pump of the host 1 works to pressurize the high-pressure air chamber. After the user selects the working mode, the air pressure foot sleeve and / or the air pressure glove start to press to the predetermined pressure. When the pressure reaches the predetermined value, the drive motor 13 starts to work. The drive motor 13 drives the second pulley 11 to rotate. The second pulley 11 drives the first pulley 10 to rotate synchronously through the synchronous belt 12. The first pulley 10 drives the screw rod 8 to rotate, thereby driving the nut 7 to move on the screw rod 8. The nut 7 drives the slider 4 to slide on the guide rail 6. The slider 4 drives the movable foot plate 2 to rotate along the hinge axis through the swing arm 5. The movable foot plate 2 rotates back and forth, thereby promoting the plantar flexion and dorsiflexion movements of the ankle joint. When the movable foot plate 2 rotates for a certain period of time, the air pressure foot sleeve and / or the air pressure glove release the pressure. After an interval of a certain time, continue to pressurize and then the movable foot plate 2 rotates. Through such cyclic actions, the blood flow rate is increased, and thrombus prevention can be better achieved.

[0032] The present invention discloses a thrombus prevention device combining the dual functions of exercise and air pressure. The ankle joint is promoted to perform plantar flexion and dorsiflexion movements through the ankle trainer. At the same time, the air pressure foot sleeve and the air pressure glove pressurize the limb during the plantar flexion and dorsiflexion movements of the ankle joint, thereby increasing the blood flow rate and being able to better prevent thrombus. The air pressure sleeve adopts a pulsed air pressure method to quickly generate high-kinetic blood flow and directly wash the lower limb veins. The ankle trainer induces regular muscle contractions through exercise stimulation, enhances the efficiency of venous return, and at the same time inhibits blood stasis. The combination of the two solutions not only overcomes the hemodynamic deficiencies of traditional instruments, but also further optimizes the prevention effect through a synergistic effect. It is especially suitable for patients during and after surgery and those who are bedridden for a long time, providing a more efficient and more universal solution for VTE prevention.

[0033] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, can make some changes or modifications to the above-disclosed technical content to obtain equivalent embodiments with equivalent changes.
