Electrostatic shield for diathermy treatment head

Abstract From the Canadian patent

Method and apparatus for minimizing or preventing the deleterious skin heating effects associated with conventional short wave diathermy treatment. The disclosed method includes attenuation of the electrostatic field transmitted by the applicator head and transcutaneous transmission of the radiated electromagnetic energy substantially unimpeded to the deep body tissues to be treated. The attenuation of the electrostatic field is performed by an electrostatic shield which is adapted, to be positioned on the diathermy applicator head between the radiating electrode and the patient receiving treatment. However the radiated electromagnetic field, which is primarily responsible for the …
