Description

An ankle joint auxiliary exercise mechanism for preventing venous thrombosis in bed

Technical Field

The invention relates to the technical field of medical training devices, and in particular to a bed-based ankle joint auxiliary training mechanism for preventing venous thrombosis.

Background Art

The ankle joint is composed of the articular surfaces of the lower ends of the tibia and fibula and the talar pulley, so it is also called the talocrural joint.

Venous thrombosis is a vascular disease caused by blood stasis and coagulation in the veins. It can occur in the patient's upper and lower limbs, among which lower limb venous thrombosis is more common. Because the thrombus can continue to grow, it can even grow into the inferior vena cava. If it falls off into the lungs, it can block the pulmonary artery and cause sudden death of the patient. Therefore, it is very dangerous for patients. There are many causes of venous thrombosis. Abnormal blood components, damage to the venous endothelium, and changes in venous blood flow rate caused by long-term stillness can all cause venous thrombosis.

At this stage, patients who can move independently should try to move their lower limbs as much as possible, especially by moving the ankle joints vigorously, which can fully mobilize the role of the calf muscle pump or the "second heart", accelerate the flow rate of venous blood in the lower limbs, and prevent deep vein thrombosis in the lower limbs. However, at this stage, when patients perform ankle rehabilitation exercises, the resistance and rotation amplitude of the feet are insufficient, so that the ankle exercises cannot achieve the effect of preventing venous thrombosis. In addition, the exercise equipment draws circles in one direction and has a single function. When the sole of the foot is plantar flexed and dorsiflexed, the foot will slide downward and leave the exercise equipment, causing the patient to lose strength and the training effect is poor. Even patients who exercise will become skeptical about the equipment for preventing venous thrombosis. At the same time, the single reciprocating motion makes the patients less interested in exercising, develop a lazy attitude, reduce the number of training sessions, and lead to a slow rehabilitation cycle. In addition, while the amount of activity is small, it is impossible to increase the amount of activity in the lower limbs through other means. In addition, some exercise equipment has a single effect and requires collaborative training by staff, which increases the workload of clinical staff.

Therefore, the present application provides a bed-based ankle joint auxiliary exercise mechanism for preventing venous thrombosis to meet the needs.

Summary of the invention

The technical problem to be solved by the present invention is to provide an ankle joint auxiliary exercise mechanism for preventing venous thrombosis in bed to solve the problem that when existing patients perform ankle joint rehabilitation exercises, the resistance and turning amplitude of the feet are insufficient, so that the ankle joint exercises cannot achieve the effect of preventing venous thrombosis. In addition, the exercise equipment draws circles in one direction and has a single function. When the sole of the foot is plantar flexed and dorsiflexed, the foot will slide downward and leave the exercise equipment, causing the patient to lose strength and the training effect is poor. Even the patients who are exercising will become skeptical about the equipment for preventing venous thrombosis. At the same time, the single reciprocating motion makes the patients less interested in the exercise, develop a lazy attitude, reduce the number of training sessions, and lead to a slow rehabilitation cycle. In addition, when the amount of activity is small, it is impossible to increase the amount of activity of the lower limbs by other means. In addition, some exercise equipment has a single effect and requires collaborative training of the staff, which increases the workload of clinical staff.

Optionally, a massage hammer is disposed on the top of the elastic support, and a plurality of groups of protrusions are disposed on the surface of the massage hammer.

Compared with the prior art, the present invention has at least the following beneficial effects:

In the above scheme, by setting a buffer massage component, using the slide block, the rack, the gear, the multi-section connecting rod and the spring seat, when the patient performs rehabilitation exercises, the heel is used to drive the sole of the foot forward for plantar flexion and dorsiflexion. The heel will move backward due to the structure of the human body, and the sole of the foot will move backward and leave the stretching plate. The slide block will offset the displacement brought by the heel through itself and the effect of the spring seat. In the process of moving the slide block, the rack drives the gear to rotate. At the same time, the multi-section connecting rod rotates. Affected by the moving distance, the gear does not rotate one circle, which will cause the rubber wheel to bulge and roll slightly on the patient's calf, bringing intermittent massage to the patient's leg, stimulating the blood vessels inside the calf, applying pressure to the outer surface, and making the blood flow faster, effectively avoiding the phenomenon of poor training effect caused by heel displacement and sole loss during patient exercise. At the same time, the use of the rubber wheel plays a synergistic function of promoting rehabilitation for the patient's leg after exercise, and provides a beneficial and rich exercise experience.

By setting up an adjustable steering assembly, utilizing an arc-shaped slide rail, utilizing an arc-shaped rack belt, utilizing the coordination between a gear seat and a rotating shaft rod, during ankle joint exercise, the sole of the foot can be subjected to plantar flexion and dorsiflexion, while being capable of inversion and eversion operations, thus avoiding the singleness of the function of the exercise equipment. At the same time, the addition of a gas spring can generate a certain amount of resistance when the patient exercises plantar flexion, requiring the patient to exert some force to complete the plantar flexion operation. The determination of the elastic telescopic rod can also adapt to different foot sizes and different degrees of foot bending of different groups of people. The flip angle of the stretching plate can be determined through the gear rocker slot, thereby maximizing the effect of the exercise equipment, and at the same time, it can be designed according to different groups of people. A certain amplitude can give the greatest feedback from the exercise, promote blood flow, and avoid the formation of venous thrombosis. At the same time, in conjunction with the plantar rehabilitation component, the piston sleeve, the segmented adjustment rod, the elastic bracket and the massage hammer are used to make the sole of the foot plantar flexion and dorsiflexion at the same time, and the gas spring displaces the piston sleeve, so that the massage hammer rolls and pierces the Yongquan acupoint and the sole of the foot to promote blood circulation in the sole. While being stressed, other exercises can be performed simultaneously, which increases the activity of the lower limbs, promotes blood circulation, increases the turning angle of the foot exercise, improves the exercise effect, increases the patient's interest in exercise, speeds up the recovery cycle, and avoids the formation of venous thrombosis.

The cushioning massage component 5 can cope with the heel's backward movement, so that the sole of the foot can better fit the stretching plate 8, and at the same time massage the calf to activate blood circulation; it includes an adjusting steering component 6. The adjusting steering component 6 is set on the right side of the rotating shaft seat 2. The adjusting steering component 6 can adapt to the strenuous steering changes of the foot, so that the sole of the foot can better fit the stretching plate 8, and at the same time meet the conditions for left and right flipping.

The stretching plate 8 includes a foot rehabilitation component 7, which is arranged inside the stretching plate 8. The foot rehabilitation component 7 is used to stimulate the acupuncture points on the soles of the patients' feet and massage the soles of the feet. First, the exercise device base 1 is moved to the end of the patient's bed. The doctor controls the gear rocker slot 11 according to the bending amplitude of the patient's own feet to lift and lower them in the rack limit seat 10, adjusts the highest climbing position of the elastic telescopic rod 9, and adjusts the pressure inside the gas spring 12. The patient places the sole of the foot on the surface of the stretching plate 8 by himself, places the heel on the rubber pad in the heel slot 4, and firmly sticks the Velcro. The foot is tightened, the sole of the foot is forced to plantar flex forward, the rotating shaft seat 2 is rotated, the receiving plate 3 is moved, and the buffer massage component 5 is driven to operate, buffering the force of the heel moving backward, and rolling the bottom of the calf to promote blood flow. At the same time, the steering component 6 is adjusted to rotate, followed by left and right flipping, inversion, eversion, plantar flexion and dorsiflexion movements. While the foot is exerting force, the stretching plate 8 is flipped, and the gas spring 12 contracts, driving the plantar rehabilitation component 7 to massage the patient's foot, promote blood circulation, speed up blood circulation, and increase the rehabilitation cycle.

As shown in Figures 4 and 5, the buffer massage component 5 includes a slide block 51, and the slide block 51 is installed at the bottom of the receiving plate 3; multiple sets of pulleys are arranged on both sides of the slide block 51, and the pulleys are slidably connected in the slide groove of the base 1. When the receiving plate 3 moves, the slide block 51 is driven to move, and the multiple sets of pulleys on both sides of the slide block 51 move in the slide groove on the inner wall of the base 1, so that the device is subjected to force to move without affecting the bottom and causing the device to deviate.

As shown in Figures 3 and 4, a rack 52 is provided on the right side of the slide block 51, and a gear 53 is meshedly connected to the surface of the rack 52. When the slide block 51 slides inside the base 1, the rack 52 follows and moves the same distance, and the meshed gear 53 rotates at the same time.

As shown in Figures 3 and 5, a multi-section connecting rod 54 is provided on one side of the gear 53, and the multi-section connecting rod 54 is provided with multiple groups, which are located on both sides of the gear 53, and the top of the multi-section connecting rod 54 is connected with a rubber wheel 55; the multi-section connecting rod 54 is composed of a paddle and an arc-shaped connecting rod, and the arc-shaped connecting rod is arranged in the inner wall groove of the receiving plate 3. When the gear 53 rotates, due to the multi-section connecting rod 54 being arranged in the inner wall groove of the receiving plate 3, the gear 53 rotates, driving the multi-section connecting rod 54 to move up and down, so that the device can perform ups and downs motion, and at the same time drives the rubber wheel 55 to act on the calf, promote blood circulation, and enhance the experience of the ankle joint.

As shown in Figures 3 and 4, a spring seat 56 is provided on the right side of the slide block 51, and the other end of the spring seat 56 is fixed on the inner wall of the base 1. When the multi-section connecting rod 54 moves up and down, the spring seat 56 acts on the slide block 51, so that it can maintain the spacing and return to its position quickly, thereby improving the exercise effect and avoiding the phenomenon of loss of strength.

As shown in Figures 1 and 6, the adjustment steering assembly 6 includes an arc-shaped slide rail 61, and the arc-shaped slide rail 61 is installed on one side of the rotating shaft seat 2. An arc-shaped rack belt 62 is arranged inside the arc-shaped slide rail 61. When the stretching plate 8 is in operation, the arc-shaped slide rail 61 limits the moving direction of the arc-shaped rack belt 62, providing conditions for left and right steering while the ankle joint performs plantar flexion and dorsiflexion.

As shown in Figures 6 and 7, the surface of the arc-shaped rack belt 62 is meshedly connected with a gear seat 63, and a rotating shaft rod 64 is installed on the surface of the gear seat 63, and the other end of the rotating shaft rod 64 is connected to the bottom of the stretching plate 8; the rotating shafts on both sides of the gear seat 63 slide inside the arc-shaped slide rail 61, and the left side of the rotating shaft rod 64 is fixedly connected to the gear seat 63, while the top of the rotating shaft rod 64 can rotate 270 degrees. When the stretching plate 8 turns, the meshing arc-shaped rack belt 62 causes the gear seat 63 and the connected rotating shaft rod 64 to produce an arc-shaped movement. At the same time, the ability of the rotating shaft rod 64 to rotate 270 degrees itself can make the stretching plate 8 follow the rotation while the foot is flipped under force, thereby increasing the fit of the foot and improving the beneficial effects of exercise.

As shown in FIG. 2 and FIG. 3 , the plantar rehabilitation assembly 7 includes a piston sleeve 71 , which is installed on the top of the gas spring 12 . When the stretching plate 8 is moved by force, the gas spring 12 contracts and moves, driving the piston sleeve 71 to move.

As shown in Figure 9, a segmented adjustment rod 72 is provided on one side of the piston sleeve 71, and an elastic bracket 73 is provided on the top of the segmented adjustment rod 72; a protrusion is provided on the top of the segmented adjustment rod 72 and rollers are provided on both sides, and the protrusion receives the spring bottom of the elastic bracket 73, and the rollers on both sides of the segmented adjustment rod 72 are installed on the inner wall of the stretching plate 8.

As shown in FIG10 , a massage hammer 74 is provided at the top of the elastic bracket 73, and a plurality of groups of protrusions are provided on the surface of the massage hammer 74. When the elastic bracket 73 contracts, the massage hammer 74 provided at the top performs a sudden contraction movement on the sole of the foot, thereby promoting blood circulation at the bottom of the foot and preventing the formation of venous thrombosis.

The working principle of the technical solution of the present invention:

First, move the exercise device base 1 to the end of the patient's bed. The doctor controls the gear rocker slot 11 according to the bending amplitude of the patient's own foot to raise and lower it in the rack limit seat 10, adjust the highest climbing position of the elastic telescopic rod 9, and adjust the pressure inside the gas spring 12. Then, the patient places the sole of the foot on the surface of the stretching plate 8 to fit it, and after placing the heel on the rubber pad in the heel slot 4, the Velcro is firmly adhered to the foot and tightened. The sole of the foot is forced to plantar flex forward, the rotating shaft seat 2 is rotated, and the receiving plate 3 is moved, driving the buffer massage component 5 to operate, buffering the force of the heel moving backward, and rolling the bottom of the calf to promote blood flow. At the same time, the steering component 6 is adjusted to rotate, and then the left and right flipping, inversion, eversion, plantar flexion and dorsiflexion movements are performed. While the foot is exerting force, the stretching plate 8 is flipped, and the gas spring 12 is contracted, driving the sole rehabilitation component 7 to massage the patient's foot, promote blood circulation, accelerate blood circulation, and improve the rehabilitation cycle.

The movement of the receiving plate 3 drives the slide block 51 to move, and the multiple groups of pulleys on both sides of the slide block 51 move in the slide groove on the inner wall of the base 1, so that the device is subjected to force to move without affecting the bottom and causing the device to deviate. When the slide block 51 slides inside the base 1, the rack 52 follows and moves the same distance, and the meshing gear 53 rotates. When the gear 53 rotates, due to the multi-section connecting rod 54 set in the groove on the inner wall of the receiving plate 3, the gear 53 rotates by itself, driving the multi-section connecting rod 54 to move up and down, causing the device to move up and down, driving the rubber wheel 55 to act on the calf, promoting blood circulation, and enhancing the experience of the ankle joint. The multi-section connecting rod 54 moves up and down, and the spring seat 56 acts on the slide block 51, so that it can maintain the spacing and return to its position quickly, thereby improving the exercise effect and avoiding the phenomenon of loss of strength.

While the stretching board 8 is operating, the arc-shaped slide rail 61 limits the moving direction of the arc-shaped rack belt 62, providing conditions for the ankle joint to turn left and right while performing plantar flexion and dorsiflexion. While the stretching board 8 is turning, the meshing arc-shaped rack belt 62 causes the gear seat 63 and the connected rotating shaft rod 64 to move in an arc shape. At the same time, the rotating shaft rod 64 itself has the ability to rotate 270 degrees, so that the stretching board 8 can follow the rotation while the foot is flipped under force, thereby increasing the fit of the foot and enhancing the beneficial effects of exercise.

When the stretching plate 8 moves under force, the gas spring 12 contracts and moves, driving the piston sleeve 71 to move. When the piston sleeve 71 moves, the two sides of the segmented adjustment rod 72 are fixed to the inner wall of the stretching plate 8, and the segmented adjustment rod 72 rotates, driving the elastic bracket 73 to contract under the action of the internal spring. When the elastic bracket 73 contracts, the massage hammer 74 arranged at the top performs a sudden contraction movement on the sole of the foot, performs rolling stabbing, promotes blood circulation in the sole of the foot, improves the exercise effect, provides a different exercise experience, and when under force and no other exercises are performed, increases the activity of the additional functions of the lower limbs, promotes blood circulation, increases the turning angle of the foot exercise, improves the exercise effect, increases the patient's interest in exercise, speeds up the recovery cycle, avoids the formation of venous thrombosis, and reduces the workload of medical staff.

The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
