Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly to an active ankle pump trainer. Background Art

[0002] Ankle pump exercise drives the contraction and shortening as well as relaxation and elongation of the triceps surae and tibialis anterior muscles through the dorsiflexion and plantar flexion of the ankle joint. At the same time, through the contraction and relaxation of the muscles, it drives the blood and lymphatic fluid to flow back and new blood perfusion, thereby strengthening the blood circulation of the entire lower limb.

[0003] Some patients need to stay in bed for a long time after surgery, which easily causes abnormal blood coagulation in the deep veins of the lower limbs, blocks blood vessels, leads to venous return disorders, and forms deep vein thrombosis in the lower limbs. Ankle pump exercise can play a role in preventing the formation of deep vein thrombosis in the lower limbs.

[0004] The existing ankle pump trainers can only achieve dorsiflexion and plantar flexion of the ankle joint, with a single movement direction and inadequate movement of the ankle joint, resulting in a decline in the effect of preventing deep vein thrombosis in the lower limbs. Content of the Utility Model

[0005] Aiming at the problems in the prior art, the utility model provides an active ankle pump trainer, which solves the problem of inadequate movement of the ankle joint caused by the single movement direction of the existing ankle pump trainer and improves the effect of preventing the formation of deep vein thrombosis in the lower limbs.

[0006] The technical solution adopted by the utility model to solve its technical problems is: an active ankle pump trainer, including a base, a fixed ring fixedly arranged on the base, a first rotating mechanism symmetrically arranged on the fixed ring, a second rotating mechanism rotatably arranged on the first rotating mechanism, and a wearing mechanism fixedly arranged on the fixed ring and the second rotating mechanism; the second rotating mechanism includes a first through hole fixedly arranged on the first rotating mechanism, a bottom plate rotatably arranged on the first through hole, a first sliding groove fixedly arranged on the bottom plate, and a moving component fixedly arranged on the bottom plate and the first rotating mechanism. The base is used to support the entire trainer; the fixed ring is used for the patient to place the calf; the first rotating mechanism is used for the patient to perform dorsiflexion and plantar flexion; the second rotating mechanism is used for the patient to rotate the ankle joint left and right; the bottom plate is used for the patient to place the foot, and the bottom plate can rotate around the first through hole; the first sliding groove is used for the movement of the moving mechanism; the moving component can provide a certain resistance when the second rotating mechanism rotates left and right, and the patient needs to apply a little force to rotate the bottom plate, improving the exercise effect.

[0007] Specifically, the first rotating mechanism includes a first bracket fixedly arranged on the fixed ring, a second through hole fixedly arranged on the first bracket, a first rotating shaft fixedly arranged on the first bracket, a second bracket rotatably arranged on the second through hole, and a second sliding groove fixedly arranged on the second bracket. The first bracket has a certain bending angle. When the patient uses it, the heel can better fit the lower end of the bottom plate, and at the same time, the ankle movement of the patient is more flexible during use; the second bracket can rotate around the second through hole; the first through hole is arranged on the second bracket; the first rotating shaft and the second sliding groove cooperate to limit the rotation angle of the second bracket, and further limit the rotation angle of the bottom plate in this direction.

[0008] Specifically, the movable assembly includes a convex block fixedly arranged on the second bracket, a plurality of limit heads fixedly arranged on the convex block, a movable plate slidably arranged on the first sliding groove, and a plurality of limit grooves fixedly arranged on the movable plate. The movable plate can slide along the first sliding groove; the limit heads and the limit grooves are arranged in cooperation.

[0009] Specifically, the wearing mechanism includes a third through hole fixedly arranged on the fixed ring, a fourth through hole fixedly arranged on the bottom plate, an elastic band passing through the third through hole and the fourth through hole, and a magic tape fixedly arranged on the elastic band. The elastic band is used to tie the patient's leg and foot. The elastic band can adapt to the legs and feet of different patients, and has good adaptability; the magic tape is convenient for pasting and cooperates with the elastic band to fix the patient's leg and foot.

[0010] Specifically, the second bracket and the first bracket are connected by a scroll spring. When the second bracket rotates, it needs to overcome the resistance of the scroll spring. The patient needs to apply a little force to rotate the bottom plate, which improves the exercise effect.

[0011] Specifically, the movable plate and the bottom plate are connected by a telescopic rod and a spring. When the patient rotates the bottom plate, since the bottom plate and the movable plate are connected by a telescopic rod, the movable plate will also rotate. The limit groove on the movable plate is misaligned with the limit head on the convex block, and the limit head presses the movable plate. The movable plate moves in the first sliding groove, the telescopic rod contracts, and the spring is compressed. When the bottom plate rotates a certain angle, the limit head re-enters the limit groove, the spring resets, pushes the movable plate to move in the first sliding groove, and the limit groove cooperates with the limit head, and the telescopic rod resets.

[0012] Specifically, the first rotating shaft and the second sliding groove cooperate. The second can slide along the first rotating shaft, and the first rotating shaft limits the sliding of the second sliding groove, thereby limiting the rotation angle of the second bracket.

[0013] Specifically, the first bracket and the fixed ring are connected by bolts.

[0014] The beneficial effects of the present utility model are:

[0015] (1) It can move in multiple directions, making the movement of the ankle joint more in place and improving the effect of preventing deep vein thrombosis in the lower extremities.

[0016] (2) When the patient performs dorsiflexion and plantar flexion, the scroll spring will generate a certain resistance, and the patient needs to exert a little force to rotate the bottom plate, improving the exercise effect.

[0017] (3) When the bottom plate rotates left and right, it needs to overcome the resistance of the spring, and the patient needs to exert a little force to rotate the bottom plate, improving the exercise effect.

[0018] (4) When the second bracket rotates around the second through hole, it needs to overcome the resistance of the scroll spring, and when resetting, the scroll spring will push the second bracket back to its original position, so that the patient can save effort and relax when resetting, realizing the cycle of "exerting force - relaxing", which helps to reduce the training burden and improve the training effect.

[0019] (5) When the bottom plate rotates left and right, it needs to overcome the resistance of the spring. When the patient overcomes the spring resistance, they need to exert force. After the limit head enters the next limit groove, the patient can relax, realizing the cycle of "exerting force - relaxing", which helps to reduce the training burden and improve the training effect.

[0026] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] As Figures 1-5As shown in the figure, an active ankle pump trainer of the present utility model includes a base 1, a fixing ring 2 fixedly arranged on the base, a first rotating mechanism 3 symmetrically arranged on the fixing ring, a second rotating mechanism 4 rotatably arranged on the first rotating mechanism, and a wearing mechanism 5 fixedly arranged on the fixing ring and the second rotating mechanism; the second rotating mechanism includes a first through hole 41 fixedly arranged on the first rotating mechanism, a bottom plate 42 rotatably arranged on the first through hole, a first sliding groove 43 fixedly arranged on the bottom plate, and a movable component 44 fixedly arranged on the bottom plate and the first rotating mechanism.

[0028] Specifically, the first rotating mechanism includes a first support 31 fixedly arranged on the fixing ring, a second through hole 32 fixedly arranged on the first support, a first rotating shaft 33 fixedly arranged on the first support, a second support 34 rotatably arranged on the second through hole, and a second sliding groove 35 fixedly arranged on the second support.

[0029] Specifically, the movable component includes a bump 441 fixedly arranged on the second support, a plurality of limit heads 442 fixedly arranged on the bump, a movable plate 443 slidably arranged on the first sliding groove, and a plurality of limit grooves 444 fixedly arranged on the movable plate.

[0030] Specifically, the wearing mechanism includes a third through hole 51 fixedly arranged on the fixing ring, a fourth through hole 52 fixedly arranged on the bottom plate, an elastic band 53 penetrating through the third through hole and the fourth through hole, and a magic tape 54 fixedly arranged on the elastic band.

[0031] Specifically, the second support and the first support are connected by a scroll spring 36.

[0032] Specifically, the movable plate and the bottom plate are connected by a telescopic rod 445 and a spring 446.

[0033] Specifically, the first rotating shaft cooperates with the second sliding groove.

[0034] Specifically, the first support and the fixing ring are connected by bolts 6.

[0035] During use, the patient inserts their leg into the fixing ring and places their foot on the bottom plate. The patient's leg and foot are fixed by the wearing mechanism. At this time, the patient can perform dorsiflexion and plantar flexion of the ankle joint. When performing dorsiflexion and plantar flexion, the second bracket rotates around the second through hole, and the second sliding groove also slides along the first rotating shaft. When one end of the second sliding groove touches the first rotating shaft, it means that the second bracket rotates to the maximum angle in this direction. The patient needs to exert force during training to overcome the resistance of the volute spring and push the second bracket and the bottom plate to rotate. The volute spring is twisted. When reset is needed, the volute spring applies a force to help the bottom plate and the second bracket reset, so that the patient can save effort and relax during reset, realizing the cycle of "exerting force - relaxing", which helps to reduce the training burden and improve the training effect. The patient can also achieve left - right rotation of the ankle joint through the second rotating mechanism. When the patient rotates the ankle joint left and right, it drives the bottom plate to rotate around the first through hole. The limiting groove on the movable plate is misaligned with the limiting head on the convex block. The limiting head presses the movable plate, and the movable plate moves in the first sliding groove. The telescopic rod contracts, and the spring is compressed. When the bottom plate rotates a certain angle, the limiting head re - enters the limiting groove, and the spring resets, pushing the movable plate to move in the first sliding groove. The limiting groove cooperates with the limiting head, and the telescopic rod resets. There are multiple limiting grooves arranged in a circular array on the movable plate, and multiple limiting heads are arranged in a rotating array on the convex block. Each time the patient only needs to rotate the bottom plate by a small angle, and the limiting head will enter the next limiting groove. The cycle of "exerting force - relaxing" can also be realized during the rotation process, which helps to reduce the training burden and improve the training effect. The patient can rotate little by little according to their own situation or rotate to the end at one time, or combine the dorsiflexion, plantar flexion and left - right rotation of the ankle joint to move the ankle joint in multiple directions, and the training methods are diverse.
