Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to a leg bone injury bending training system. Background Art

[0002] Patients with bone injuries, especially those in the legs, have very weak leg strength and are basically unable to move on their own. Over time, due to lack of leg exercise, the leg muscles will atrophy and the entire body's internal functions will deteriorate.

[0003] The application with the announcement number CN208130148U provides a medical leg flexion recovery exercise device, which belongs to the field of medical exercise and includes a box. A strip plate is vertically fixed to the rear side of the middle position of the ground in the bottom plate of the box. The upper side of the front end surface of the strip plate is connected to a cam through a rotating shaft in a horizontal position in the front and rear direction. A motor is fixed to the outer end surface of the rear side plate of the box, and the main shaft of the motor passes through the rear side plate of the box and is fixed to the rotating shaft connected to the cam. A battery box is fixed to the lower side of the inner end surface of the left side plate of the box. The stable plate of the utility model facilitates the box to be placed stably on the ground. When the cam rotates clockwise and contacts the left edge of the top plate, it slides relatively to the left along the lower end surface of the top plate, and at the same time pushes the top plate upward, so that the movable rod rises. When the cam cam rotates and disengages from the right side of the lower end surface of the top plate, the top plate falls with the movable rod under the action of gravity. Due to the repeated rotation of the cam, the movable rod reciprocates up and down.

[0004] However, the leg muscles of bedridden patients atrophy, and the device only exercises the bending of the legs when used, but cannot massage the leg muscles, speed up blood circulation, and cannot quickly restore the patient's legs.

[0005] The application with announcement number CN218979624U provides a leg bending exercise mechanism for orthopedics, including a base plate, and a leg erection mechanism is fixedly installed on the left side of the top of the base plate.

A screw is rotatably connected inside the rolling bearing, and the bottom end of the screw passes through the rolling bearing and extends to the outside thereof and is fixedly connected to a driven bevel gear, and a stepper motor is fixedly installed on the outside of the fixed shell. The leg bending exercise mechanism for orthopedics has a reasonable design and is easy to use. Patients can perform autonomous leg bending exercises according to their own leg length, height, and degree of rehabilitation, and can effectively adjust the pulling force. It has a high scope of application and practicality, and fully meets the use requirements.

[0006] Likewise, the device only exercises the bending of the legs when in use, but cannot massage the leg muscles, accelerate blood circulation, and cannot quickly restore the patient's legs.
