AI Technical Summary
Existing lower limb muscle strengthening devices cause discomfort in the upper trunk and lower limb muscles when used for extended periods, and also prevent patients from turning over, affecting their comfort.
A multifunctional lower limb muscle strength training device was designed. Through the cooperation of the lower limb lifting plate, connecting slide bar and connecting rod, the patient is allowed to roll over to the side while the lower limb is in a limited lifting state. The curvature of the guide slot compensates for the displacement of the foot, so as to realize the synchronous rolling of the upper trunk and lower limbs and avoid maintaining the same side lying position for a long time.
It improves patient comfort during use, accelerates blood return through side-lying and reduces muscle fatigue, and does not require the upper torso to move laterally to adapt to the lower limb position, thus enhancing the ease of use of the device.
