Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training, in particular to a rehabilitation training system for lower limb superficial vein thrombosis. Background Art

[0002] Superficial vein thrombosis of the lower limbs refers to thrombosis occurring in the great saphenous vein or small saphenous vein of the lower limbs and their surrounding areas. Patients with superficial vein thrombosis of the lower limbs need to wear medical elastic stockings to promote venous blood return to the heart. After wearing the medical elastic stockings, the highest support pressure is established at the ankle, and gradually decreases upward along the leg, reducing to 70%-90% of the maximum pressure value in the gastrocnemius muscle, and reducing to 25%-45% of the maximum pressure value in the thigh. This decreasing change in pressure can promote venous blood return in the lower limbs, effectively relieve or improve the pressure on the lower limb veins and venous valves, and significantly improve the clinical symptoms of venous insufficiency. When patients with superficial venous thrombosis of the lower limbs who wear medical elastic stockings undergo rehabilitation training, the passive movement of the patient's lower limbs is not only likely to cause the medical elastic stockings to fall off and deform during exercise, but also likely to accelerate the wear of the medical elastic stockings, and even cause scratches to the medical elastic stockings, resulting in a reduction in the plastic effect of the medical elastic stockings, and failure to achieve a good effect of promoting venous blood return to the heart. In addition, the downward extension of one lower limb is likely to drive the other lower limb with the knees bent, causing the non-exercising lower limb to move and change the position of the lower limb. When the lower limb on this side is straightened, it is easy to cause the extension direction of the patient's lower limb to change, causing the foot to extend outside the foot auxiliary module, increasing the chance of the elastic stockings worn on the patient's lower limbs being scratched. Therefore, in response to the above problems, a rehabilitation training system for superficial venous thrombosis of the lower limbs is proposed. Summary of the Invention

[0003] The purpose of the present invention is to provide a rehabilitation training system for lower limb superficial vein thrombosis to solve the problems raised in the above background technology.

When the bevel gear ring assembly rotates, the return spring storage mechanism is charged, and the center shaft assembly is driven to rotate after the stored force reaches a certain level.

[0005] Furthermore, control switch assemblies are provided on both sides of the control assembly, and the control switch assemblies are used to control the motor drive assembly. The lower limb flexion and extension module is connected to the threaded drive rod through a threaded sleeve. After the control assembly starts the control switch assembly on the right, the threaded rod is driven to drive the lower limb flexion and extension module to the right. After the control assembly starts the control switch assembly on the left, the threaded rod is driven to drive the lower limb flexion and extension module to the left.

[0006] Furthermore, the bottom support auxiliary positioning assembly located below the foot placement frame is symmetrically arranged front to back, and the slide integration is located on the inner side of the lower limb rehabilitation training body, which is opposite to the slide direction of the slide integration in the lower limb rehabilitation training body. Different positions of the slide integration limit the lifting slide assembly differently.

[0007] Furthermore, an arc-shaped penetrating rod is provided on the inner side of the thigh anti-roll side plate, and the arc-shaped penetrating rod is passed through the thigh support pad, and the arc-shaped penetrating rod limits the sliding of the thigh support pad.

[0008] Furthermore, a micro-tilt auxiliary eccentric roller is provided at the bottom end of the hip auxiliary pad, and the micro-tilt auxiliary eccentric roller is connected to a micro planetary speed change assembly through a common shaft, and the micro planetary speed change assembly limits the rotation of the micro-tilt auxiliary eccentric roller.

[0009] Furthermore, a hip auxiliary linkage mechanism is provided between the central shaft assembly and the micro planetary speed change assembly, so that the central shaft assembly drives the micro planetary speed change assembly to operate when it rotates. The hip auxiliary linkage mechanism includes a worm assembly and a worm gear assembly. The worm assembly is connected to the central shaft assembly, and the worm gear assembly is connected to the micro planetary speed change assembly.

[0010] Furthermore, the method of using the device is as follows:

[0011] Step 1: Have the patient with superficial vein thrombosis of the lower limbs wearing medical elastic stockings sit on the hip auxiliary module, and place the patient's lower limb ankles on the foot support frame. The patient is then asked to lie down with the patient's buttocks positioned above the hip auxiliary pad and the patient's thighs positioned above the thigh support pad.

[0012] Step 2: The patient applies force with his foot to drive the foot placement frame and the control assembly, causing the control switch assembly to control the motor drive assembly to move the lower limb flexion and extension module within the lower limb rehabilitation training module;

[0013] Step 3: As the lower limb flexion and extension module moves to the right, it drives the patient's foot closer to the patient's hip, causing the patient's lower limb to gradually bend the knee and stand upright. The thigh anti-tilt side plate extends and, together with the thigh support pad, supports and folds the patient's thigh.

[0014] Step 4: The patient exerts force on one side of the foot to make the corresponding lower limb flexion and extension module move to the left, so that the patient can extend the leg. After pausing for 1 second, the patient's lower limb continues to bend the knee and stand upright, and the lower limb is changed to perform leg extension training. Repeat 10 times as a set, and repeat 3 sets.

[0015] Compared with the prior art, the present invention allows the foot rest frame to always fit the patient's ankle during the rehabilitation training of alternating leg extension for patients with superficial vein thrombosis of the lower limbs who are wearing medical elastic stockings, thereby reducing the phenomenon of the medical elastic stockings at the patient's ankle falling off, deforming, or even scratching and wearing out due to the friction between the medical elastic stockings and the bed surface during the leg extension process. In addition, during the alternating leg extension process, the slide groove in the slide groove assembly limits and changes the position of the lifting slide assembly, so that the elastic force of the elastic reset mechanism between the lifting slide assembly and the support auxiliary positioning assembly changes, thereby providing a certain force to assist the fit between the foot rest frame and the patient's ankle.

[0016] Compared with the prior art, in the present invention, during the movement of the lower limb flexion and extension module, the return spring storage mechanism on the outside of the central axis assembly is charged. After the charge is stored, the central axis assembly is driven to rotate, so that the thigh anti-roll side plate extends upward to shield the thigh part of the lower limb of the patient with the knees bent and upright, ensuring the stability of the lower limbs of the patient with the knees bent and upright when alternately extending the legs, and will not be driven by the lower limb of the patient on the other side of the leg being extended, avoiding the patient's lower limbs from extending in the wrong direction when alternately extending the legs.

[0017] Compared with the prior art, in the present invention, when the central shaft assembly drives the thigh anti-roll side plate to rise, the micro-tilt auxiliary eccentric roller is rotated together through the transmission of the hip auxiliary linkage mechanism and the micro planetary speed change assembly, supporting the hip auxiliary pad and driving the hip auxiliary pad to produce a certain inclination, ensuring the fit and support of the hip auxiliary pad to the patient's buttocks, making the patient more comfortable.

The bevel gear ring assembly 161 is arranged on the outside of the central shaft assembly 15, and a return spring storage mechanism is provided between the bevel gear ring assembly 161 and the central shaft assembly 15. When the bevel gear ring assembly 161 rotates, the force spring storage mechanism is stored, and the central shaft assembly 15 is driven to rotate after the stored force reaches a certain level.

[0029] Specifically, control switch components 9 are provided on both sides of the control assembly 3. The control switch components 9 are used to control the motor drive assembly. The lower limb flexion and extension module 2 is connected to the threaded drive rod through a threaded sleeve. After the control assembly 3 starts the control switch component 9 on the right, the threaded rod is driven to drive the lower limb flexion and extension module 2 to move to the right. After the control assembly 3 starts the control switch component 9 on the left, the threaded rod is driven to drive the lower limb flexion and extension module 2 to the left.

[0030] Specifically, the bottom support auxiliary positioning assembly 10 located below the foot placement frame 4 is symmetrically arranged front to back, and the slide groove integration 12 is located on the inner side of the lower limb rehabilitation training body 1, and is opposite to the slide groove direction of the slide groove integration 12 in the lower limb rehabilitation training body 1. Different positions of the slide groove integration 12 limit the lifting slide assembly 11 differently.

[0031] By adopting the above-mentioned technical solution: In the present invention, during the rehabilitation training of alternating leg extension for patients with superficial vein thrombosis of the lower limbs wearing medical elastic stockings, the foot placement frame 4 is always in contact with the patient's ankle, reducing the phenomenon of the medical elastic stockings at the patient's ankle falling off, deforming, or even scratching and wearing due to friction with the bed surface during leg extension.

The patient uses force through the ankles to drive the foot support frame 4 and the control assembly 3 to move in the lower limb flexion and extension module 2, and starts the control switch component 9. The control switch component 9 drives the motor drive mechanism to drive the threaded drive rod to rotate, so that the lower limb flexion and extension module 2 slides in the lower limb rehabilitation training body 1 until the patient's lower limbs are bent and upright, and in this process, the movement of the lower limb flexion and extension module 2 drives the lifting slide assembly 1 1 slides on the slide integration 12, and the slide in the slide integration 12 limits and changes the position of the lifting slide assembly 11, so that the elastic force of the elastic reset mechanism between the lifting slide assembly 11 and the support frame auxiliary positioning assembly 10 changes, thereby causing the support frame auxiliary positioning assembly 10 to be under the elastic force of the elastic reset mechanism. In the process of the lower limb flexion and extension module 2 moving from left to right, the opening direction of the foot placement frame 4 gradually moves from right to left, so that the foot placement frame 4 is always in contact with the patient's ankle, avoiding the medical elastic stockings worn by the patient to fall off, deform or even be scratched and worn due to friction with the table board during the alternating leg extension rehabilitation training, and ensuring that the medical elastic stockings promote the lower limb venous return of patients with lower limb superficial vein thrombosis during the alternating leg extension rehabilitation training.
