Electro pulse arthritic physiotherapy system

Claim 1

An electro-pulse arthritic physiotherapy system for providing an output electronic stimulative impulse to a mammalian subject comprising an alternating current source; a switch means connected to said source; a first transformer having a primary and a secondary; said switch and primary being connected in series with said source; a bridge rectifier; said rectifier being connected to said secondary of said first transformer; said rectifier having first and second outputs; a first resistance; a second transformer having a primary and secondary; said first resistance being connected to said first output; a circuit including a first capacitor connected between said first resistance and the second output; a first Zener diode; a second resistance; said Zener diode and said second resistance being connected in a series circuit between said first resistance and second output of said bridge rectifier; a silicon controlled rectifier having a gate lead; the primary of said second transformer and said silicon controlled rectifier being connected in a circuit in series between said first resistance and second output; and said first capacitance circuit, said Zener diode circuit and said second transfomer primary circuit all being arranged in parallel; said gate lead of the silicon controlled rectifier being connected in to said Zener diode circuit between the Zener diode and second resistance; first and second pins forming output connections for the secondary of said second transformer; a variable resistance connected between said first and second pins in parallel with said secondary of said second transformer; a first electrode for attachment to a mammalian subject; a third resistance; means to connect said third resistance in series with said electrode and a portion of said variable resistance; a second electrode for attachment to a mammalian subject; a first diode; a fourth resistance; a second Zener diode; said second electrode, said first diode and said fourth resistance being connected in series with said second pin; said second Zener diode being connected between said third and fourth resistance elements, and also in parallel with the secondary of said second transformer; a second capacitor connected in parallel with said first diode and said fourth resistance; a second diode connected between said first diode and said second capacitor; a voltmeter connected in parallel with said second capacitor; and a fifth resistance connected between said second capacitor and said voltmeter.
