Abstract

The invention discloses a variable-rigidity soft pneumatic rehabilitation hand. The rehabilitation hand comprise a glove, soft drivers are arranged on five fingers of the glove, each soft driver comprises a soft driver cavity, a cavity is formed in the bottom of each soft driver cavity and connected to an air pump through a hose, the upper surface of each driver cavity is in a comb tooth shape, and the comb tooth density at the finger joints is smaller than that at the finger backs. The rehabilitation hand can help a patient with disabled hands to do hand exercising.

Description

technical field [0001] The invention belongs to the field of medical rehabilitation training robots, in particular to a soft pneumatic rehabilitation hand with variable stiffness. Background technique [0002] In today's world, due to the aging population, hand disabilities are becoming more and more common. The prevalence of diseases such as stroke has placed an increasing burden on our nation's financial resources and physical therapy personnel. According to the World Health Organization survey, the incidence of stroke in China is much higher than that in developed countries such as the United States. It is difficult for patients with hand disabilities to complete the most basic daily activities such as eating and dressing, which brings great inconvenience to patients. In order to reduce the impact of stroke on patients, an effective method is to allow patients to perform repetitive rehabilitation exercises to improve the strength, grasping accuracy, and range of motion ...
