摘要

Abstract A heating system for a peritoneal dialysis apparatus comprising: a pumping apparatus configured to pump dialysate into or out of a heater bag; an electric heater configurable to operate at an AC line voltage in a range of about 100 to 120 volts or an AC line voltage in a range of about 200 to 240 volts; a heater controller configured to control a temperature of the dialysate using the electrical heater; and a universal power supply configured to convert line voltage to one or more DC voltages to power the pumping apparatus and heater controller, and to configure the electric heater to operate at a voltage in a range of about 100 to 120 volts or in a range of about 200 to 240 volts, based on a measured current flow through the electrical heater.
