Development of neuromuscular rehabilitation instrument based on USB / 医疗卫生装备

A neuromuscular rehabilitation instrument, with USB bus to supply power and transmit data, is developed to improve the existing product which has low data transmission rate and is at the high cost of battery. Its circuits, including the circuits for singlechip interface, power, EMG amplifiers and filters, MCU, electrode interface and stimulation, are designed. The software of singlechip and PC are also described. The system powering, data transmission, display and storage of EMG are realized. Experiments show that it is reliable.
