    摘要： A portable device for alleviating menstrual pain through transcutaneous electrical nerve stimulation (TENS) and thermal stimulation includes a transcutanous electrical nerve stimulating electrode pad and a planar heater embedded in the stimulating electrode pad. The stimulating electrode pad is a patch type one which is attachable/detachable to/from any body part with menstrual pain. The device further includes a power portion for supplying power to the menstrual pain alleviating unit, and an operation processing portion for generating a transcutaneous stimulating electrode control signal for controlling the transcutaneous stimulating electrode pad and a planar heater control signal for controlling the planar heater. The device further includes a temperature sensor mounted on the planar heater to sense the temperature of the planar heater, and an A/D converter for converting the signal output from the temperature sensor into a digital signal.
