Apparatus for maintaining the negative potential of organic cells and/or for the penetration of substances into such cells

Claim 1

1 An apparatus for maintaining the negative potential of human, animal and vegetable cells and/or for the penetration of substances into the cells, comprising a generator and control circuit means for producing bursts of high frequency electrical signal for application to a treatment head for producing a high frequency electromagnetic field for treatment of the cells, the bursts being of adjustable repetition frequency, amplitude and duration and a d c circuit for selectively producing a continuous constant d c voltage and a pulsating d c voltage for the ionization and d c pulses of predetermined shape and variable repetition frequency for the faradization of the tissue to be treated; means connected to the outputs of said generator and d c circuit for selectively applying the high frequency bursts, the ionization voltage and the faradization pulses produced thereby to the body; indicator means for indicating the magnitude of signals supplied to the applying means; means connected to the outputs of said d c circuit for selectively connecting the d c circuit outputs to calibration circuit elements having a load characteristic similar to that of the cells to be treated; and means for adjusting the level of signals produced and displayed on said indicator means while said elements are connected, whereby desired signal levels can be established before application thereof to the cells.
