Abstract ▼ AI-Helper

The human body and nervous system transmit information through electric charges. After the electric charge transmits information to the brain, we can feel pain, numbness, comfort, and other feelings. Electric therapy is currently used widely in clinical practice because the field of examination is more representative of electrocardiogram, and in the field of treatment is more representative of electrotherapy. In this study, we design a system for neurophysiological therapy and conduct parameter calculation and model selection for the components of the system. The system is based on a discontinuous conduction mode (DCM) boost circuit, and controlled and regulated by a single-chip microcomputer. The system does not only have a low cost but also fully considers the safety of use, convenience of the human-computer interface, adjustment sensitivity, and waveform diversity in the design. In future, it will have strong implications in the field of electrotherapy.

제안 방법

A production sample and MCU program were created according to the design, the graph was plotted by voltage monitoring, and the relationship between the PWM1 duty cycle pulse and voltage was obtained through linear regression. Density, sine, and triangle waves are often used in physiotherapy.
The circuit design of the system was carried out, and the DC/DC boost and output wave circuit were designed in detail. The DCM boost method was adopted because the boost multiple was large and the load was small, and the inductance of the DCM boost circuit was calculated.

대상 데이터

The system mainly includes power, boost circuit, output pulse control, voltage, and current measurement modules, two single-chip microcomputers, MCU1 and MCU2, an alarm, and a touch screen, as shown in Fig. 1.
