Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
212 words
A therapeutic treatment apparatus utilizing superimposed DC and AC voltages, said apparatus comprising: therapeutic voltage generating means for generating an output comprising superimposed DC and AC voltages, means for producing a therapeutic electric field including first and second parallel opposed electrodes, and means for connecting the output of said therapeutic voltage generating means to said electrodes, said therapeutic voltage generating means including transformer means comprising a primary winding adapted to be connected to an AC power source, and first and second secondary windings, one of said secondary windings forming an AC generating circuit, a rectifier means, means for connecting said rectifier means to the other of said secondary windings so as to form a DC generating circuit, and means for connecting said DC generating circuit to said AC generating circuit in a mutually superimposed relationship to therapeutic voltage terminals so that an output comprising superimposed DC and AC voltages is presented at said terminals, said therapeutic voltage terminals being connected respectively to said opposed electrodes of said therapeutic electric field producing means and one of said electrodes being adapted to be connected to the subject for therapeutic treatment, the AC voltage presented at said terminals being a low AC voltage as compared to the AC voltage used in conventional therapeutic treatment apparatus.
