A recently granted patent (Publication Number: US11934246B2) discloses a power supply device designed for use with electromedical devices. The device includes a power supply unit that provides power to the electromedical device, along with first and second impedance control units strategically placed along the power circulation path. These impedance control units transition between high and low impedance states based on the power supply status to ensure efficient power delivery and device operation. The first impedance control unit is in a low impedance state during power supply periods and transitions to a high impedance state during power stop periods, while the second impedance control unit operates in the opposite manner.

Furthermore, the patent details a relay device and method for controlling the power supply device in electromedical systems. The relay device includes impedance control units that adjust impedance states based on the power supply status, ensuring seamless power delivery and signal transmission between the power supply unit, electromedical device, and other external devices. The method involves transitioning between power supply and power stop states based on the power supply status to effectively manage power distribution and signal transmission within the electromedical system. Overall, the patented technology aims to enhance the efficiency and reliability of power supply in electromedical devices, ensuring optimal performance and functionality in various medical applications.
