Patent ID: 7483734

Claim:
A treatment device for applying electrical impulses to a living body via the skin, for non-invasively treating a variety of clinical conditions, comprising: a pair of electrodes for contact with the skin; a waveform generator for repeatedly generating an AC waveform for applying electrical impulses through the electrodes to the skin; a detector for detecting the skin impedance responsive to the applied electrical impulses and for generating detection signals representing the skin impedance; means responsive to the detector output signals for monitoring the responsivity of the skin; and indicator means activated by the monitoring means for generating a first indication when a predetermined level of responsivity is reached and a second indication when a pre-determined treatment has been administered, wherein: the detector generates detector output signals in the form of pulses whose duration represents the skin impedance; the monitoring means measures the duration t of each pulse; and the indicating means is arranged to generate each indication when t satisfies a predetermined function of t.
