AI Technical Summary
Existing hand grasping training devices have poor adaptability, limited feedback mechanisms, and are mostly passive training methods, which affect rehabilitation outcomes and patient compliance.
It adopts a linkage structure of airbag, air pressure sensor and micro air pump to dynamically adjust resistance, and combines hollow hinge and compression spring to simulate human hand movement, and is equipped with honeycomb piezoelectric sensor to provide tactile and visual feedback.
It enables dynamic adjustment of resistance based on the patient's real-time grip strength, reducing the risk of joint stiffness and improving rehabilitation compliance, and motivating patients to actively participate through tactile and visual dual channels.
