Electric body stimulator and test instrument

摘要

A signal generator supplies a periodically varying treatment signal of ultrasonic frequency and given voltage and current to electrodes applied to a living body to be treated. A retrievable record of the time of treatment is stored in digital form and the voltage and current are sensed and analog representations are fed to a normally disabled analog to digital converter. - The converter is enabled by synchronising pulses from a separate test instrument and the analog representations converted to digital form are latched and loaded into a shift register array with the stored record of the treatment time and shifted out serially to the instrument by clock pulses generated by the latter. The data output from the register is selected for display by actuation of one of several buttons.
