Abstract
A transcutaneous pain reliever which utilizes a plurality of battery powered inductive energy generators, which are sequentially and individually activated, a clocking system which has means for automatically inhibiting pulsing of an energy generator until a previous energy generator has delivered its energy, and an antiadapt system to prevent a patient from becoming acclimated to the sensations. The invention also includes an energy absorption sensor which will indicate the amount of energy not absorbed by the electrodes, a bridged, transformerless battery charger which will permit the use of inexpensive low power diodes and a battery saver which may be used to permit excess energy to charge batteries.
