Description

Technical Field

[0001] The utility model relates to the technical field of medical training, in particular to an ankle pump exercise device for preventing deep vein thrombosis of lower limbs. Background Art

[0002] Deep vein thrombosis of the lower extremities is a common vascular disease, and its formation is usually related to long-term bed rest, surgery, trauma or other factors that slow blood circulation or increase blood coagulation. Once venous thrombosis is formed, it may cause swelling and pain in the lower extremities, and may fall off and cause more serious complications, such as pulmonary embolism. Preventing the formation of deep vein thrombosis in the lower extremities is of vital importance for many patients, especially postoperative patients or those who are bedridden for a long time. Ankle pump exercise, that is, flexion and extension exercise of the ankle joint, promotes blood circulation and lymphatic return in the lower extremities by simulating the action of a pump. This exercise helps prevent the formation of deep vein thrombosis in the lower extremities, and also helps to relieve symptoms such as swelling and pain in the lower extremities. Ankle pump exercise devices came into being.

[0003] After searching, the Chinese patent number CN114209542B discloses an ankle pump exercise device for preventing deep vein thrombosis of the lower extremities, which relates to the technical field of medical training devices, and is intended to solve the problem that the patient's ankle pump exercise is relatively subjective, it is difficult to judge whether it is effective exercise, and the compliance is not high. For high-risk patients, doctors will prescribe passive exercise or other passive treatments to prevent it. It includes a base assembly, a moving assembly is installed at the top center of the base assembly, the top of the base assembly and the moving assembly are jointly connected to a moving mechanism, the outside of the moving mechanism is connected to a driven assembly, and the corner of the moving mechanism is connected to a vertical plate.

[0004] Compared with the prior art, the Chinese patent number CN114209542B fixes the patient's feet inside two sets of pedal assemblies respectively, and the first servo motor drives the worm to rotate, so that the worm wheel drives the connecting rod to rotate counterclockwise, and then the first bracket and the second bracket drive the two sets of pedal assemblies to rotate counterclockwise around the connecting rod to achieve dorsiflexion, and the first servo motor drives the worm to rotate, so that the worm wheel drives the connecting rod to rotate clockwise, and then the first bracket and the second bracket drive the two sets of pedal assemblies to rotate clockwise around the connecting rod to achieve plantar flexion, so that the patient can passively perform ankle pump exercises.

[0005] However, during actual use of the above device, when curling the toes, the user may forget or fail to curl the toes for other reasons. If the toes are not curled, the contraction and relaxation patterns of the muscles will be different, which will lead to failure to fully activate the tibialis anterior and triceps surae, thereby affecting the return effect of blood and lymph. In addition, the rotation axis position of the pedal assembly is fixed, which will affect the effect of the ankle pump exercise. Therefore, an ankle pump exercise device for preventing deep vein thrombosis of the lower limbs is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0032] See also Figure 1-6As shown, the present invention is an ankle pump exercise device for preventing deep vein thrombosis of lower extremities, comprising a base 1 and a foot pedal 8, a rotating shaft 5 for controlling the rotation of the foot pedal 8 is arranged outside the base 1, the foot pedal 8 is arranged outside the support frame 6, a fixed adjustment mechanism for adjusting the axis position of the support frame 6 is arranged outside the rotating shaft 5, and the fixed adjustment mechanism includes a fixed plate 12 symmetrically arranged outside the rotating shaft 5;

[0033] The foot pedal 8 is externally rotatably connected to a toe board 10 which always tends to remain parallel to the foot pedal 8. The foot pedal 8 is internally slidably connected to a control push plate 15 for pushing the toe board 10 to rotate. A control spring 16 is provided between the foot pedal 8 and the control push plate 15. A gravity block 17 is provided on the side of the control push plate 15 away from the control spring 16. The toe board 10 and the foot pedal 8 tend to remain parallel. When the control push plate 15 contacts the toe board 10 and pushes the toe board 10, the toe board 10 can be controlled to rotate, so that the angle between the toe board 10 and the foot pedal 8 is increased.

[0034] The working principle of the ankle pump exercise device for preventing deep vein thrombosis of lower limbs proposed by the present invention is that when the user performs the ankle pump exercise, he first places his foot on the foot pedal 8, the foot pedal 8 is tightly fitted with the foot, and the rotating shaft 5 is controlled to rotate back and forth, that is, the support frame 6 and the foot pedal 8 are controlled to perform the stepping and hooking of the foot in the ankle pump exercise;

[0035] When stepping on the foot, the support frame 6 and the foot pedal 8 tend to be horizontal, and the gravity component force of the gravity block 17 along the direction of the foot pedal 8 is smaller than the force of the control spring 16, that is, the toe plate 10 remains stationary;

[0036] When hooking the foot, the support frame 6 and the foot pedal 8 tend to be vertical, and the gravity component of the gravity block 17 along the direction of the foot pedal 8 is greater than the force of the control spring 16, that is, the control push plate 15 moves downward under the action of the gravity block 17, and the control push plate 15 contacts the toe plate 10 during the movement, and then the control push plate 15 squeezes the control toe plate 10 to rotate, and the angle between the toe plate 10 and the foot pedal 8 increases, and the toe plate 10 rotates to push the toe part, so as to hook the toes upward at the maximum angle, thereby improving the completion degree of the ankle pump movement;

[0037] When doing ankle pump exercises, the axis of foot rotation is located at a position upward from the sole of the foot. The position may vary for different users. When the axis position needs to be adjusted, the control shaft 13 is controlled to rotate. The control shaft 13 rotates to drive the two fixed plates 12 closer together, so that the force between the fixed plate 12 and the sliding groove 11 is smaller, that is, the connecting frame 7 can be slidably adjusted with the fixed plate 12. The connecting frame 7 is controlled to adjust to a suitable position, and the control shaft 13 is rotated in the reverse direction. The two fixed plates 12 are controlled to move away from each other, and the fixed plate 12 fixes the connecting frame 7 again.

[0038] The utility model provides the gravity block 17, the control push plate 15, the control spring 16 and the toe plate 10, so that the user can step on the foot normally. When the user hooks the foot, the toe plate 10 can help to hook the toe upward at the maximum angle, thereby improving the degree of ankle pumping. At the same time, by adjusting the position of the connecting frame 7 relative to the rotating shaft 5, the axis position of the support frame 6 is changed when doing the ankle pumping exercise, so as to adapt to different users.

The connecting frame 7 is opened on the outside of the sliding groove 11 for adjusting the relative position of the connecting frame 7 and the rotating shaft 5. The inner wall of the sliding groove 11 is rough to increase the friction between the fixed plate 12. By controlling the two fixed plates 12 to slightly move away from the inner wall of the sliding groove 11, the friction between the sliding groove 11 and the fixed plate 12 is reduced. At this time, the support frame 6 and the connecting frame 7 can be controlled to slide through the sliding groove 11 and the fixed plate 12 to change the axial position of the support frame 6 when it rotates.
