The invention discloses a single-phase power supply array type dual-phase electrical stimulation feedback system. A microcontroller module sends out a control signal to coordinate and control a dual-phase electrical stimulation pulse generation module and a multichannel electrical stimulation electrode array module; the double-phase electrical stimulation pulse generation module receives a controlsignal of the microcontroller module so as to generate an adjustable dual-phase electrical stimulation pulse to be output to the multi-channel electrical stimulation electrode array module; the multi-channel electrical stimulation electrode array module receives control signal of the microcontroller module and converts the two-phase electrical stimulation pulse into electrical stimulation in realtime, and adjusts and changes electrode and the intensity; the single-phase power supply module is used for supplying power. The invention is advantageous in that the system is used for the intelligent feedback of limb sensing, and the technical problem that an existing electrical stimulation feedback system cannot enable a user to feel multiple modes without electric stimulation feedback havingno electric shock is solved; the forward and reverse directions of the current can be rapidly switched, and the electric stimulation feedback with multiple modes and no electric shock can be realized.
Description
technical field [0001] The invention belongs to an electric stimulation feedback system in the field of medical rehabilitation equipment, and relates to a single-phase power array type biphasic electric stimulation feedback system applied to limb perception feedback. Background technique [0002] Physical disabilities and nervous system diseases (especially sensory disturbances in limbs) have become one of the major diseases in our country. Limbs play an extremely important role in daily life, and people who lose control and perception of their limbs will face great inconvenience in daily life. Loss of limb perception can use assistive perception devices. At present, the interactive system of commercial prosthetics lacks appropriate sensory feedback, which affects the convenience and functionality of using prosthetics. Prosthetics and auxiliary equipment with sensory feedback systems can improve the accuracy of movements during operation, reducing to a certain extent Depen...
