Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ankle joint assistive devices, in particular to an ankle joint movement assistive device. Background Art
[0002] The ankle joint, also known as the talocrural joint, is formed by the articular surfaces of the lower ends of the tibia and fibula and the talar trochlea. The talar trochlea (articular head) is housed in a "冂"-shaped socket formed by the inferior articular surface of the tibia and the medial and lateral malleolus. Because the trochlea is wide in front and narrow in the back, the wider front portion of the socket enters during dorsiflexion, stabilizing the joint. However, during plantar flexion, such as when walking downhill, the narrower rear portion of the trochlea enters the socket, loosening the ankle joint and allowing lateral movement. This makes the ankle prone to sprains, with inversion being the most common injury. This is because the lateral malleolus is longer and lower than the medial malleolus, preventing excessive talar eversion.
[0003] Existing ankle joint exercise aids require patients to actively move when in use. However, for patients with ankle injuries, they cannot meet the purpose of passively exercising the ankle, so they are not applicable and have the defect of poor applicability. Utility Model Content

[0031] Example 2:
[0032] like Figure 2 As shown, the structure of an ankle joint exercise aid disclosed in the second embodiment of the present invention is basically the same as that in the first embodiment, except that:
[0033] A support base 2 is fixedly connected to the middle of one end of the base 1 , a rotating shaft 3 is fixedly connected to the middle of the support base 2 , and sliding rods 4 are fixedly connected to both sides of one end of the base 1 .

[0038] Through the setting of the arc seat 5, when in use, both sides of the arc seat 5 are rotatably connected with the connecting blocks 6, and the connecting blocks 6 are slidably connected to the surface of the slide rod 4, so that the arc seat 5 can move up and down and can be rotated at will, thereby achieving a more comfortable wearing effect for the user.
[0039] Example 3:
[0040] like Figures 3 and 4 As shown, the structure of an ankle joint exercise aid disclosed in the third embodiment of the present invention is basically the same as that in the second embodiment, except that:
[0041] The surface of the rotating shaft 3 is rotatably connected to a pedal 11 , the top surface of the pedal 11 is fixedly connected to an anti-slip protection pad, one end of the bottom end of the pedal 11 is fixedly connected to a sleeve 12 , and the interior of the sleeve 12 is rotatably connected to the surface of the rotating shaft 3 .
[0042] A slide groove 13 is provided at one end of the top of the pedal 11, and limiting grooves 14 are provided on both sides of the slide groove 13. A bearing 15 is fixedly connected to one end of the slide groove 13, and a threaded rod 16 is rotatably connected to the middle of the bearing 15. The other end of the threaded rod 16 is fixedly connected to a knob 17.
[0043] The top end of the slide groove 13 is slidably connected to an arc-shaped baffle 18 , and the bottom end of the arc-shaped baffle 18 is fixedly connected to a slider 19 . Both sides of the slider 19 are fixedly connected to limit blocks 20 , and the limit blocks 20 are slidably connected to the inside of the limit groove 14 .
[0044] The bottom end of the pedal 11 abuts against the top of the first airbag 23, the middle of the top of the pedal 11 is fixedly connected with a second Velcro 22, the other end of the top of the pedal 11 is fixedly connected with a protective cover 21, and the top of the protective cover 21 abuts against the bottom end of the second airbag 24.
[0045] By setting the arc baffle 18, the arc baffle 18 is slidably connected to one end of the top of the pedal 11 when in use, and the threaded rod 16 is driven to rotate by turning the knob 17. The rotation of the threaded rod 16 can drive the arc baffle 18 to slide left and right on the surface of the pedal 11, so that the distance between the arc baffle 18 and the protective cover 21 can be adjusted at will, so that it can be suitable for people with different foot sizes, thereby greatly improving the scope of application.
[0046] The specific solution is as follows: first place the sole of the foot on the top of the pedal 11, then turn the knob 17 to fit the arc baffle 18 with the heel. Through the setting of the arc baffle 18, the arc baffle 18 is slidably connected to one end of the top of the pedal 11 when in use, and the threaded rod 16 is driven to rotate by turning the knob 17. The rotation of the threaded rod 16 can drive the arc baffle 18 to slide left and right on the surface of the pedal 11, so that the distance between the arc baffle 18 and the protective cover 21 can be adjusted at will, so that it can be suitable for people with different foot sizes, thereby greatly improving the scope of application. Then, the sole of the foot is fixed to the pedal 11 through the second Velcro 22, and then the arc seat 5 is adjusted to a suitable height. Then, the leg is fixed to the arc seat 5 through the first Velcro 8. Through the setting of the arc seat 5, the arc is fixed to the top of the pedal 11 when in use. Both sides of the arc seat 5 are rotatably connected with connecting blocks 6, and the connecting blocks 6 are slidably connected to the surface of the slide bar 4, so that the arc seat 5 can move up and down and rotate at will, so as to achieve a more comfortable wearing effect for the user. Then the user steps on the pedal 11, and the bottom end of the pedal 11 squeezes the first airbag 23. The first airbag 23 is under pressure and the internal gas is transported to the inside of the second airbag 24 through the trachea 25. The second airbag 24 will expand and squeeze the patient's foot to assist the patient's foot to move downward. Conversely, the patient lifts the foot and squeezes the second airbag 24. The second airbag 24 transmits the internal gas to the inside of the first airbag 23 through the trachea 25 to make the pedal 11 move upward. Repeating this training can achieve active ankle pump exercise. At the same time, this exercise can stimulate the patient's interest in exercise. The ankle joint exercise aid is mainly used for patients who have been bedridden for a long time or have undergone lower limb surgery to prevent deep vein thrombosis, reduce swelling and promote blood circulation. Through the setting of the first airbag 23 and the second airbag 24, when in use, the top and bottom ends of the pedal 11 are each in contact with an airbag. When the ankle joint flexes and extends, the airbag can be squeezed by the sole and instep of the foot to drive the pedal 11 up and down, thereby achieving the effect of active training, and at the same time, it can achieve effective buffering and play a safety protection effect.
