Description

Technical Field

[0001] The utility model relates to the technical field of physical therapy devices, in particular to an automatic exercise auxiliary device for preventing lower limb thrombosis. Background Art

[0002] Patients who have undergone surgery are at higher risk for blood clots in their lower extremities, especially if they have been bedridden for long periods of time or have limited mobility. Thrombosis may lead to serious complications, such as deep vein thrombosis (DVT) or pulmonary embolism. Ankle pump exercises have a positive effect on relieving blood clots in the lower extremities. They help relieve patients’ conditions and promote recovery by accelerating blood flow in the lower extremity veins, promoting local blood circulation, reducing swelling, and increasing muscle strength.

[0003] The Chinese patent document with the authorization announcement number CN210543140U discloses a rehabilitation device for ankle pump exercise for patients, including a fixed bottom plate, the upper sides of the first support rod and the second support rod are fixedly connected with a pedal rod, the outer wall of the pedal rod is sleeved with a sponge pad, the outer wall of the first torsion spring rod is sleeved with a first torsion spring, and the outer wall of the second torsion spring rod is sleeved with a second torsion spring. With respect to the above technical solution, the following defects still exist: the existing device completely relies on the patient's active force, which makes it difficult for the patient to persist, and it is difficult to control the amplitude of the exercise, resulting in a lack of appropriate standards during the exercise process. If the patient's exercise amplitude is too large, it may have an adverse effect on rehabilitation.

[0004] Therefore, an automatic motion assisting device for preventing lower limb thrombosis is proposed. Utility Model Content

[0024] like Figures 1 to 3As shown, an automatic motion-assisting device for preventing lower limb thrombosis comprises a base plate 1, a calf supporting assembly 2 is fixedly connected to the right side of the top surface of the base plate 1, a first supporting plate 3 is fixedly connected to the front of the base plate 1, a second supporting plate 4 is fixedly connected to the back of the base plate 1, a fixing plate 5 is arranged between the first supporting plate 3 and the second supporting plate 4, a binding assembly 6 for limiting the position of the patient's foot is arranged on the surface of the fixing plate 5, a control assembly 7 for controlling the rotational motion of the fixing plate 5 is installed on the surfaces of the first supporting plate 3 and the second supporting plate 4, and a limiting assembly 8 for controlling the rotation angle of the fixing plate 5 is arranged on the surface of the first supporting plate 3. More specifically, when the user needs to perform lower limb activities, the base plate 1 is placed on the surface of the bed, and the patient's calf is placed on the surface of the calf support component 2, so that the sole of the foot fits with the surface of the fixed plate 5. The patient's foot can be fixed by the binding component 6, and the motion control component 7 can be operated to drive the fixed plate 5 to rotate to the left and right sides, driving the patient's ankle to move automatically, thereby promoting blood circulation and preventing thrombosis. The limit component 8 can limit and adjust the range of rotation of the fixed plate 5 controlled by the motion control component 7.

[0025] The calf support assembly 2 includes an arc-shaped support plate 201, and the arc-shaped support plate 201 is fixedly connected to the top surface of the bottom plate 1, and a support pad 202 is fixedly connected to the top surface of the arc-shaped support plate 201, and the support pad 202 is made of sponge. It should be noted that when the patient's foot is attached to the surface of the fixing plate 5, the calf part is placed on the surface of the arc-shaped support plate 201 to support the bottom of the calf, and the softness is increased by the support pad 202, making the leg placement more comfortable.

[0026] The binding assembly 6 includes a strap 601, and the strap 601 is fixedly connected to the fixing plate 5, the end of the strap 601 is fixedly connected to a Velcro 602, and the left side of the fixing plate 5 is fixedly connected to a Velcro 603. More specifically, after the sole of the patient is attached to the surface of the fixing plate 5, the strap 601 is pulled and wrapped around the instep of the patient, and then the Velcro 602 and the Velcro 603 are bonded, so that the patient's foot is fixed to the surface of the fixing plate 5.

[0027] The motion control assembly 7 includes a motor 701, and the motor 701 is fixedly mounted on the surface of the second support plate 4, the output end of the motor 701 is fixedly connected to a rotating shaft 702, and the rotating shaft 702 is fixedly connected to the fixed plate 5, and the rotating shaft 702 is rotatably connected to the second support plate 4 and the first support plate 3. It should be noted that by running the motor 701, the output end thereof is driven to rotate, thereby driving the rotating shaft 702 to rotate, and the fixed plate 5 can be controlled to rotate.

[0028] The limiting assembly 8 includes a baffle 801, and the baffle 801 is fixedly connected to the end of the rotating shaft 702. An arc groove 802 is formed through the surface of the first support plate 3. Two slide rods 803 are slidably connected to the inner wall of the arc groove 802. A pressure sensor 805 is fixedly installed on the surface of the slide rod 803. A protrusion 804 is fixedly connected to the surface of the slide rod 803, and the protrusion 804 is slidably connected to the front surface of the first support plate 3. The rear end of the slide rod 803 is threadedly connected to a screw rod 806, and the rear end of the screw rod 806 is fixedly connected to a knob 807. The surface of the screw rod 806 is rotatably connected to a pressure plate 808, and the pressure plate 808 is in contact with the back surface of the first support plate 3. More specifically, when the rotating shaft 702 drives the fixed plate 5 to rotate, the rotating shaft 702 will synchronously drive the baffle 801 to rotate. When the baffle 801 rotates to a certain angle, it will come into contact with the pressure sensor 805. The pressure sensor 805 detects the pressure. At this time, the motor 701 immediately controls the rotating shaft 702 to rotate in the opposite direction, thereby limiting the range of rotation of the rotating shaft 702 and the fixed plate 5 in one direction. The position of the pressure sensor 805 can be adjusted by sliding the slide bar 803 along the inner wall of the arc groove 802. By turning the knob 807, the screw rod 806 is driven to rotate. Under the action of the thread, the screw rod 806 will move toward the slide bar 803, thereby driving the pressure plate 808 to move until the pressure plate 808 touches the back of the first support plate 3, thereby fixing the slide bar 803.

[0029] A rubber layer is provided on the front of the pressing plate 808. It should be noted that by providing the rubber layer, the friction force with the surface of the first support plate 3 is increased, so that the pressing plate 808 contacts the surface of the first support plate 3 more tightly and stably.

[0030] In summary: when the user needs to perform lower limb activities, the base plate 1 is placed on the surface of the bed, and the patient's calf is placed on the surface of the calf support component 2, so that the sole of the foot fits with the surface of the fixing plate 5. The patient's foot can be fixed by the binding component 6, and the motion control component 7 can be operated to drive the fixing plate 5 to rotate to the left and right sides, and drive the patient's ankle to move automatically, thereby promoting blood circulation and preventing thrombosis. The range of rotation of the fixing plate 5 controlled by the motion control component 7 can be limited and adjusted by the limit component 8. During use, the effect of assisting the patient's ankle to exercise is achieved, and it does not rely on the patient's completely independent force, making the exercise process easier to stick to, and the amplitude of the ankle movement can be controlled to avoid excessive amplitude and adverse effects on rehabilitation.
