Embodiment Construction

[0019] The invention discloses a rehabilitation training mechanism for active and passive upper and lower limbs with double output shafts, which includes a mechanical arm, a tray, a force sensor, a DC motor, a magneto-rheological damper, a lifting platform, a spur gear and a bevel gear and the components. Three of the robotic arms can be installed as needed to perform rehabilitation training on the upper and lower limbs respectively. The magneto-rheological damper and the DC motor are connected in parallel through a pair of spur gears. The DC motor completes the active and passive modes and power-assisted mode in rehabilitation training. In the damping training mode, the magnetorheological damper generates safe and reliable damping force to ensure the safety of patients. . The force sensor is installed in series with the DC motor to measure the rotational force between the hand and the robotic arm during the patient's exercise, and the lifting column can be adjusted to differe...

Description

technical field [0001] The invention relates to a rehabilitation training device applied to patients with limb dysfunction caused by stroke, spinal cord injury and various accidents, in particular to a dual-axis active and passive rehabilitation training mechanism for upper and lower limbs. Background technique [0002] Rehabilitation medicine is one of the four major medical disciplines. With the development of rehabilitation medicine engineering, more and more attention has been paid to the complete rehabilitation of patients. Sports rehabilitation training is currently the most widely used rehabilitation medical project. Clinical research on rehabilitation medicine shows that stroke patients Rehabilitation training of affected limbs is a very important and key medical method. For patients with limb dysfunction caused by stroke, spinal cord injury and various accidents, timely rehabilitation training, especially correct rehabilitation training within the first three months...
