Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a medical ankle brace for ankle joint rehabilitation training and a use method thereof. Background Art

[0002] Lateral ankle instability is mostly caused by repeated sprains, and a small part is caused by repeated inversion stress activities. After undergoing lateral ankle structure reconstruction surgery, lateral ankle instability is mostly caused by repeated sprains, and a small part is caused by repeated inversion stress activities. During the rehabilitation training of ankle injuries, wearing medical ankle braces to assist is beneficial to help patients recover.

[0003] In the prior art, for example, an ankle joint rehabilitation trainer disclosed in the national patent publication number CN212592974U drives the slider to make vertical reciprocating motion through a driving assembly, thereby driving the push rod to make axial telescopic motion relative to the crankshaft body, so that the crankshaft body can rotate, and then drive the pedal to make circular motion, thereby training the patient's ankle joint.

[0004] The above scheme has poor adjustability and practicality. Due to the differences in the thickness of the patients' calves, the shape of the calf guard is fixed and cannot fully fit the patient's calf, and the tightness cannot be adjusted, so the fixation may be loose or the tightening force may be too large, which will cause discomfort to the patient and is not conducive to the rehabilitation training. In addition, during the rehabilitation training, the patient's ankle joint is subjected to long-term twisting training, the ankle joint heats up and sweats, and the calf muscles are prone to soreness after training. The humanized design is insufficient and the usage experience is poor, which can easily lead to patients' psychological rejection of medical ankle guards and their unwillingness to actively train, affecting the rehabilitation process. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a medical ankle brace for ankle joint rehabilitation training and a method of using the same to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0050] See also Figure 7 A method for using a medical ankle brace for ankle joint rehabilitation training comprises the following steps:

[0051] S1, the patient's foot passes through the elastic bands 3 and the annular sleeve 19 in sequence from above and then extends into the footrest 9;

[0052] S2, the rack 30 is pushed to move by the hydraulic cylinder 5, and the rack 30 drives the gear 29 to rotate, and then drives the reel 4 to rotate, tightening the elastic band 3 to fix the patient's calf, and the light-emitting sheet 6 emits green light to the skin of the patient's calf, and part of the green light is absorbed by the blood in the skin. After the patient's calf is tightened, the less blood there is, the greater the intensity of the green light received by the photosensitive sheet 7, and the hydraulic cylinder 5 is automatically controlled to stop working;

[0053] S3, the motor 12 drives the pedal member 9 to twist upward and downward along the rotating shaft 10 to assist the patient in squatting and stepping training. The pedal member 9 is controlled to twist upward ten times and then twist downward ten times as a training cycle. 3-5 training cycles are performed every day to restore the patient's ankle joint range of motion and strength in all directions.

[0054] S4, after the training is completed, the hydraulic cylinder 5 is controlled to retract, the elastic band 3 is loosened, and the patient lifts his legs and ankles upwards to get out of the exercise.

[0055] Working principle: the patient's foot passes through the elastic bands 3 and the annular sleeve 19 in sequence from the top and extends into the pedal 9, then the hydraulic cylinder 5 is started to operate, the hydraulic cylinder 5 pushes the rack 30 to move, the rack 30 drives the gear 29 to rotate, and then drives the reel 4 to rotate, tightens the elastic band 3, and fixes the patient's calf. When the elastic band 3 is tightened on the patient's calf, the blood there is reduced, and the amount of green light absorbed by the light-emitting sheet 6 is reduced, then the intensity of green light received by the photosensitive sheet 7 increases, at this time, the controller 8 can be used to control the hydraulic cylinder 5 to stop working, complete the tightening of the patient's calf, and automatically tighten and fix the patient's calf to ensure effective training, and the tightening strength of the elastic band 3 can be automatically adjusted and controlled according to the thickness of the patient's calf, further improving the comfort feeling, reducing the patient's psychological rejection of medical ankle brace, and helping to speed up the training and rehabilitation process;

[0056] The motor 12 is started to rotate forward, and the motor 12 drives the rotating rod 13 to rotate forward. Since the incomplete bevel gear 14 and the driven bevel gear 15 are meshed with each other, when the rotating rod 13 drives the incomplete bevel gear 14 to rotate, the teeth on the incomplete bevel gear 14 intermittently contact and mesh with the driven bevel gear 15, driving the driven bevel gear 15 to rotate intermittently. After the teeth on the incomplete bevel gear 14 are out of contact with the driven bevel gear 15, the clockwork spring 11 drives the driven bevel gear 15 to rotate and reset, thereby realizing the control of the pedal member to reciprocate and deflect upward by a certain angle. By controlling the forward or reverse rotation of the motor 12, the pedal member 9 can be driven to deflect upward or downward, thereby assisting the patient in squatting training and foot-raising training, with stable operation and flexible use.

[0057] During the reciprocating deflection process of the pedal member 9, the piston 17 is driven to slide reciprocally in the sealing tube 16, so as to continuously pump air into the annular sleeve 19. The air is blown to the ankle of the patient through the exhaust hole 20 on the inner side wall of the annular sleeve 19, so as to reduce the temperature and prevent sweating, thereby further improving the user experience.

[0058] During the rehabilitation training of the ankle, the cam 24 is driven to rotate by the rotating rod 13, and the cam 24 intermittently squeezes the elastic airbag 23. The air in the elastic airbag 23 is squeezed into the airbag ball 22 by the gap, so that the airbag ball 22 periodically swells and collapses, which has a massage effect on the patient's calf muscles and relieves the patient's muscle soreness after training. It is a more humane design and does not require the installation of additional power drive devices or massage equipment, thereby reducing costs, so that the patient's ankle joint rehabilitation training, cooling and sweat removal and leg massage can be coordinated and carried out in conjunction.

[0059] It will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, the scope of the invention being defined by the appended claims and their equivalents.
