Description

A leg bone injury rehabilitation device

Technical Field

The utility model belongs to the technical field of rehabilitation devices, and in particular relates to a leg bone injury rehabilitation device.

Background Art

Traumatology is a science that studies the prevention and treatment of injuries and diseases of the human skin, tendons, bones, qi and blood, internal organs and meridians. Injuries to the tendons and bones of the legs often occur in normal work and life. When the tendons and bones of the legs are injured, in order to ensure the effect of recovery, it is necessary to use leg bone injury rehabilitation devices to help with recovery.

The existing leg muscle training devices have a fixed training angle during the training process, and the training intensity cannot be adjusted according to the rehabilitation effect.

The existing patent (application number: CN202120469694.9) is a leg muscle training device for bone injury rehabilitation training. A mounting frame is installed on the surface of the base through a support mechanism. The angle of the mounting frame can be adjusted by adjusting the support height of the telescopic support rod in the support mechanism, so that the training angle of the training device can be adjusted to meet the usage needs of different groups of people. A counterweight block is arranged in the training device through an assembly groove. The weight of the pedal frame can be adjusted by adjusting the assembly number of the counterweight block, thereby adjusting the training intensity, which is convenient for training of different intensities.

In response to the above problems, existing patents have provided solutions, but in actual use, patients can only recover their legs through active training, which is only suitable for patients whose legs have fully recovered. Training may also cause secondary damage to the patient's leg muscles and bones, and it is unable to automatically perform active rehabilitation of the patient's leg joints. The applicability is poor and needs to be improved.

Therefore, a leg bone injury rehabilitation device is proposed.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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 embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-5. The utility model provides a technical solution: a leg bone injury rehabilitation device, including a base 1, a seat 2 is fixedly installed on the base 1, a mounting box 3 is fixedly installed on the base 1, a forward and reverse motor 4 is fixedly installed on the mounting box 3 close to the seat 2, a screw 5 is rotatably arranged in the mounting box 3, the end of the output shaft of the forward and reverse motor 4 is fixedly installed with the end of the screw 5, a bracket 6 is slidably arranged on the mounting box 3, the center of the bottom plate of the bracket 6 spirally rotates with the screw 5, a symmetrical foot pedal 7 is arranged above the bracket 6, and a movable part 8 is arranged on the top plate of the bracket 6.

When automatically rehabilitating the patient's leg muscles and bones, the patient first sits on the seat 2 and places both feet on the footrests 7 respectively, and then starts the forward and reverse motors 4 on the sides of the mounting box 3. The output shafts of the forward and reverse motors 4 rotate to drive the screw 5 to rotate in the mounting box 3. The rotation of the screw 5 drives the bracket 6 to slide on the mounting box 3 for horizontal reciprocating motion. The horizontal reciprocating motion of the bracket 6 drives the footrest 7 to move horizontally. While the footrest 7 moves horizontally, the patient's leg joints are automatically rehabilitated. When the patient needs to actively perform rehabilitation exercises on his legs, the footrest 7 is driven by the bracket 6 to move to a suitable position, and then both feet are placed on the footrest 7 respectively and pedal the footrest 7 hard. The setting of the movable part 8 can drive the footrest 7 to move to exercise the patient's legs. The leg bone injury rehabilitation device can automatically perform active rehabilitation on the patient's leg joints, and the patient can also actively perform rehabilitation exercises on his legs, which is beneficial to improving the rehabilitation effect of the patient's legs. It has a simple structure and strong practicality.

The movable part 8 includes a slide 81 symmetrically opened on the top plate of the bracket 6, a movable block 82 slidably set on the slide 81, and a spring 83 set in the slide 81. The top of the movable block 82 is fixedly installed on the bottom of the foot pedal 7, and the spring 83 is pressed between the bracket 6 and the movable block 82. The patient places both feet on the foot pedal 7 and pushes the foot pedal 7 hard, so that the foot pedal 7 is driven by the force to drive the movable block 82 to compress the spring 83 and move horizontally on the slide 81. The patient's legs are exercised and rehabilitated by the force and restoring force of the spring 83. The structure is simple and practical.

The size of the movable block 82 is matched with the size of the slideway 81, which can improve the stability of the footrest 7 when it moves horizontally and improve the stability of the patient's legs when exercising.

Connecting plates 9 are fixedly installed at both ends of the spring 83, and connecting ports 10 are provided on the sides of the movable block 82 and the bracket 6 near the end of the spring 83. The connecting plate 9 is slidably set in the connecting port 10, and the connecting plate 9 is fixedly installed with the movable block 82 and the top plate of the bracket 6 by screws respectively; the connection plate 9 and the connecting port 10 are provided to facilitate the installation of the spring 83.

At least two groups of symmetrical connection ports 10 are arranged in each group of the slideways 81; multiple groups of springs 83 can be installed in the slideways 81 to increase the training intensity of the patient's legs.

The surface of the footrest 7 is provided with evenly distributed anti-skid patterns 11, which can prevent the patient's feet from slipping.

The seat 2 is configured as a lift chair; the height of the seat 2 can be adjusted according to the height of the patient, and the seat is highly applicable.

A controller is provided on the handle of the seat 2, and the controller is electrically connected to the forward and reverse motor 4; the controller is provided to automatically control the motor.

The footrests 7 are all provided with elastic bands 12; the elastic bands 12 can prevent the patient's feet from being separated from the footrests 7 when the patient's legs move, thereby improving the stability during leg movements and providing high safety.

Working principle: When the patient's leg muscles and bones are automatically rehabilitated, the patient first sits on the seat 2 and places both feet on the footrests 7 respectively, and then starts the forward and reverse motors 4 on the side of the mounting box 3. The output shaft of the forward and reverse motor 4 rotates to drive the screw 5 to rotate in the mounting box 3. The rotation of the screw 5 drives the bracket 6 to slide on the mounting box 3 for horizontal reciprocating motion. The horizontal reciprocating motion of the bracket 6 drives the footrest 7 to move horizontally. While the footrest 7 moves horizontally, the patient's leg joints are automatically rehabilitated. When the patient needs to actively perform rehabilitation exercises on his legs, the footrest 7 is driven by the bracket 6 to move to a suitable position, and then both feet are placed on the footrest 7 respectively and pedal the footrest 7 hard, so that the footrest 7 is subjected to the force to drive the movable block 82 to move horizontally on the slide 81 under the compression of the spring 83, and the patient's legs are exercised and rehabilitated through the action force and restoring force of the spring 83.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
