Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation therapy, in particular to an autonomous ankle pump exercise trainer for bedridden patients. Background Art

[0002] Lower limb venous thrombosis is a common peripheral vascular disease. The venous valve insufficiency and concurrent pulmonary embolism caused by lower limb venous thrombosis are a major threat to the patient's labor and life safety. The three main factors of deep vein thrombosis are venous blood flow stagnation, venous wall damage and hypercoagulable state of blood. If not treated in time, it can easily cause pulmonary embolism, thrombosis, post-thrombotic syndrome, etc.

[0003] In order to promote venous recanalization, improve local blood circulation, control complications after deep vein thrombosis, such as lower limb swelling, skin pigmentation, and even ulcer formation, restore limb function, and reduce lost ability to work, patients are usually asked to undergo exercise therapy. Common exercise therapies include raising the lower limbs, ankle pump exercises, knee flexion and extension, hip rotation, alternating leg extension, etc. Among them, ankle pump exercises are exercises for the ankle joint.

[0004] Traditional autonomous ankle pump exercise trainers for bedridden patients usually have relatively simple functions. The exercise method is to let the foot swing with the ankle joint as the axis to exercise the flexibility of the ankle. The ankle joint can not only swing back and forth, but also swing left and right. When exercising in the left and right directions, the existing technology usually uses a standing trainer to train the patient's stability when standing. It is inconvenient for the patient to get out of bed and move around during the early stage of bedridden treatment, so it is difficult for the patient to exercise. Or another type of left and right swinging trainer is used, but medical staff needs to replace the trainer, which is time-consuming and labor-intensive. Therefore, the existing technology lacks an autonomous ankle pump exercise trainer for bedridden patients that can swing back and forth, left and right to exercise flexibility when the patient is in bed. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an autonomous ankle pump exercise trainer for bedridden patients to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an autonomous ankle pump exercise trainer for bedridden patients, comprising a base, wherein a first motor and a guide rod are respectively arranged inside the base, and the output end of the first motor is connected to a first screw rod through a first reducer, a guide frame is connected between the first screw rod and the guide rod, and a second motor is installed on the top of the guide frame, the output end of the second motor is connected to a second screw rod through a second reducer, and a push plate is connected between the second screw rod and the guide frame, a ball sleeve is connected inside the push plate, a ball head seat is fixed at the lower part of the base, and a ball head rod passes through the top of the ball head seat.

[0007] By adopting the above technical solution, after limiting the position of the patient's legs and feet, the medical staff can start the first motor and the second motor through the control button. After the first motor is started, the output end drives the first screw to rotate through the first reducer, and at the same time cooperates with the guide stop of the guide rod, so that the guide frame carries the second motor, the second reducer, the second screw, the push plate and the ball sleeve to move left and right. After the second motor is started, the output end drives the second screw to rotate through the second reducer, and at the same time cooperates with the guide stop of the guide frame to make the push plate carry the ball sleeve to move forward and backward. After the push plate is displaced, it pushes the ball head rod through the ball sleeve to make the ball head rod rotate in the ball head seat, so that the ball head rod drives The placement frame is tilted so that the ankle joint can be adjusted to any angle and in any direction within a positive or negative sixty-degree angle, and the first reducer and the second reducer can drive the first screw and the second screw to rotate slowly after the first motor and the second motor output power, thereby preventing the placement frame from rotating too fast and spraining the patient's ankle; after the training, the medical staff turns off the first motor and the second motor through the control button. Since the first reducer and the second reducer are worm gear reducers, they have a good self-locking effect and the placement frame is limited when stopped, so that the trainer can act as a splint to prevent the patient's ankle from moving around and being damaged when the patient is sleeping.

[0008] Furthermore, the guide frame is threadedly connected to the first screw rod, and the guide frame is slidably connected to the guide rod.

[0009] By adopting the above technical solution, after the first motor is started, the output end drives the first screw to rotate through the first reducer, and at the same time cooperates with the guide stop of the guide rod to make the guide frame carry the second motor, the second reducer, the second screw, the push plate and the ball sleeve to move left and right.

[0010] Furthermore, the push plate is threadedly connected to the second screw rod, and the push plate is slidably connected to the guide frame.

[0011] By adopting the above technical solution, after the second motor is started, the output end drives the second screw to rotate through the second reducer, and at the same time cooperates with the guide stop of the guide frame to make the push plate carry the ball sleeve to move forward and backward.

[0012] Furthermore, the ball sleeve is rotatably connected to the push plate, and the ball head rod is rotatably connected to the ball head seat, and the ball head rod is slidably connected to the ball sleeve.

[0013] By adopting the above technical solution, the push plate pushes the ball head rod through the ball sleeve after displacement, so that the ball head rod rotates in the ball head seat, thereby causing the ball head rod to drive the placement frame to tilt, so that the ankle joint movement can be adjusted to any angle and direction within a positive or negative sixty degree angle.

[0014] Furthermore, the first motor and the second motor are both servo motors, and the first reducer and the second reducer are both worm gear reducers.

[0015] By adopting the above technical solution, the first motor and the second motor are both servo motors, which are convenient for precise control. The first reducer and the second reducer can drive the first screw rod and the second screw rod to rotate slowly after the first motor and the second motor output power, thereby preventing the placement frame from rotating too fast and spraining the patient's ankle. The first reducer and the second reducer are worm gear reducers with good self-locking effect. When stopped, the placement frame is limited, so that the trainer can act as a splint to prevent the patient's ankle from moving around while sleeping and resting, causing damage.

[0016] Furthermore, a plurality of control buttons are installed below one side of the base, and the first motor and the second motor are electrically connected to the control buttons, and a placement rack is fixed on the top of the ball head rod.

[0017] By adopting the above technical solution, the medical staff places the patient's calves on the base and the patient's feet in the placement frame. After limiting the patient's legs and feet, the medical staff can turn on the first motor and the second motor through the control button.

[0018] Furthermore, one side of the base and the placement rack are both connected to a limiting belt, and a Velcro fur surface is fixed to one side of the limiting belt, and the other side of the base and the placement rack are both connected to a Velcro hook surface.

[0019] By adopting the above technical solution, the medical staff places the patient's calf on the base and places the patient's foot in the placement frame. The placement frame can be made of aluminum alloy material, which has a light structure, high strength and no pollution, and the structure is rigid to prevent the patient's feet from moving at will. Then the medical staff wraps the top of the patient's calf with the limiting belt on the base, and wraps the patient's instep with the limiting belt on the placement frame. Then the medical staff limits the limiting belt with the Velcro hook surface and the Velcro fleece surface, which is convenient and quick to wear, and stable and not easy to loosen.

[0020] Furthermore, the limiting belt is made of skin-friendly materials such as latex and needle-punched cotton.

[0021] By adopting the above technical solution, medical staff wrap the limiting belt on the base around the top of the patient's calf, and wrap the patient's instep with the limiting belt on the placement rack. The material of the limiting belt has good breathability to reduce discomfort and avoid pressure sores.

[0022] Furthermore, support plates are connected to the upper sides of both sides of the base through a first damping shaft, and support feet are connected to the bottoms of the two support plates through a second damping shaft.

[0023] By adopting the above technical solution, medical staff can rotate the support plate and the support foot to increase the support area between the base and the mattress, so that the trainer can be similar to a T-shoe to prevent the patient's foot from dropping when sleeping. At the same time, resistance can be applied to the support plate and the support foot through the first damping shaft and the second damping shaft to prevent the support plate and the support foot from rotating at will, and a large force is required to unfold and fold the support plate and the support foot.

[0024] Furthermore, the support foot is rotatably connected to the support plate via a second damping shaft, and the support plate is rotatably connected to the base via a first damping shaft.

[0025] By adopting the above technical solution, resistance can be applied to the support plate and the support feet through the first damping shaft and the second damping shaft, so as to prevent the support plate and the support feet from rotating at will, and a large force is required to unfold and fold the support plate and the support feet.

[0026] In summary, the present invention mainly has the following beneficial effects:

[0027] 1. The present invention is provided with a first screw, a guide frame, a second screw, a push plate, a ball sleeve, a ball head seat and a ball head rod. The first screw drives the guide frame left and right to move the push plate left and right, and the second screw drives the push plate to move forward and backward. After the push plate moves, it pushes the ball head rod through the ball sleeve to rotate the ball head rod in the ball head seat, so that the ball head rod drives the placement frame to tilt, so that the ankle joint movement can be adjusted to any angle and direction within a positive and negative sixty degree angle; the flexibility is very good, effectively avoiding the phenomenon of poor training effect caused by a single direction, and convenient for patients to train while lying in bed;

[0028] 2. The present invention arranges the first reducer and the second reducer so that the first motor and the second motor can output power and then drive the first screw and the second screw to rotate slowly, thereby preventing the placement frame from rotating too fast and spraining the patient's ankle. The first reducer and the second reducer are worm gear reducers with good self-locking effect. When stopped, the placement frame is limited, so that the trainer can act as a splint to prevent the patient's ankle from moving around and causing damage when sleeping and resting. It can have a good protective effect and effectively reduce the occurrence of secondary injuries during exercise and rest. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Embodiment three:

[0044] On the basis of the above-mentioned embodiment 1, in order to facilitate quick wearing, the following settings are now adopted.

[0045] See also Figure 1-Figure 5 In the above embodiment, one side of the base 1 and the placement rack 22 are connected to a limiting belt 7, and the limiting belt 7 is made of skin-friendly materials such as latex and needle-punched cotton, which has good air permeability, reduces discomfort and avoids pressure sores; one side of the limiting belt 7 is fixed with a Velcro fleece surface 8, and the other side of the base 1 and the placement rack 22 are connected with a Velcro hook surface 9, which has a simple structure and is convenient and quick to wear.

[0046] The implementation principle of the present invention is as follows: first, the medical staff places the patient's calf on the base 1 and places the patient's foot in the placement frame 22. The placement frame 22 can be made of aluminum alloy material, which has a light structure, high strength and no pollution, and a rigid structure to prevent the patient's foot from moving at will. Then, the medical staff wraps the top of the patient's calf with the limiting belt 7 on the base 1, and wraps the patient's instep with the limiting belt 7 on the placement frame 22. Then, the medical staff limits the limiting belt 7 with the Velcro hook surface 9 and the Velcro fur surface 8, which is convenient and quick to wear, and stable and not easy to loosen;

[0047] After limiting the position of the patient's legs and feet, the medical staff can turn on the first motor 10 and the second motor 15 through the control button 2. After the first motor 10 is started, the output end drives the first screw 12 to rotate through the first reducer 11, and at the same time cooperates with the guide stop of the guide rod 13 to make the guide frame 14 carry the second motor 15, the second reducer 16, the second screw 17, the push plate 18 and the ball sleeve 19 to move left and right. After the second motor 15 is started, the output end drives the second screw 17 to rotate through the second reducer 16, and at the same time cooperates with the guide stop of the guide frame 14 to make the push plate 18 and the ball sleeve 19 move left and right. The plate 18 carries the ball sleeve 19 to move forward and backward. After displacement, the push plate 18 pushes the ball head rod 21 through the ball sleeve 19, so that the ball head rod 21 rotates in the ball head seat 20, so that the ball head rod 21 drives the placement frame 22 to tilt, so that the ankle joint movement can be adjusted at any angle and in any direction within a positive and negative sixty degree angle, and the first reducer 11 and the second reducer 16 can drive the first screw rod 12 and the second screw rod 17 to rotate slowly after the first motor 10 and the second motor 15 output power, so as to avoid the placement frame 22 rotating too fast and spraining the patient's ankle;

[0048] After the training, the medical staff turns off the first motor 10 and the second motor 15 through the control button 2. Since the first reducer and the second reducer 16 are worm gear reducers, they have a good self-locking effect. When stopped, the placement frame 22 is limited, so that the trainer can act as a splint to prevent the patient's ankle from moving around while sleeping and causing damage. The medical staff can rotate the support plate 3 and the support foot 5 to increase the support area between the base 1 and the mattress, so that the trainer can be similar to a T-shoe to prevent the patient's foot from sagging while sleeping. At the same time, the first damping shaft 4 and the second damping shaft 6 can apply resistance to the support plate 3 and the support foot 5 to prevent the support plate 3 and the support foot 5 from rotating at will. A large force is required to unfold and fold the support plate 3 and the support foot 5.
