Abstract
Abstract An apparatus for current pulse action upon the central nervous system, wherein current pulses are applied from a unit for rhythmic current pulse action upon the central nervous system of a patient, via a unit for regulating the duration of said current pulses, a unit for regulating the amplitude of said current pulses, and a unit for indicating the mean value of current intensity, to the patient. The current pulses are applied through electrodes, i.e. attached in the patient's forehead area, and an anode, secured in the neck area, below the mastoids.

Claim 1
Independent Claim
319 words
An apparatus for current pulse action upon the central nervous system, comprising in combination: a first means for rhythmic current pulse action upon the central nervous system of a patient, said first means having an input and an output; second means for regulating the duration of said current pulses, said second means attains in the central nervous system the second level of the first stage of general electro-anaesthesia without causing any side effects in said patient, and which has a first input and a second input and one output, said second means being electrically connected with its first input to said output of said first means; third means for regulating the amplitude of said current pulses, said third means having a first input and a second input, a first output and a second output, said third means having its first input electrically connected to said output of said second means; fourth means for indicating the mean current intensity value, said fourth means having an input and an output and being connected with its input to the first output of said third means; anode means connected to said output of said fourth means for attachment to the neck area of said patient, just under the mastoids; cathode means connected to said output of said fourth means for attachment to the forehead area of said patient; patient protection means having one input and two outputs, whose first output is connected to a power-supply, and whose second output is connected to fifth means for indicating the amplitude current value; said power-supply having an input and an output, said output connected to said input of said first means and said second inputs of said second and third means, said input connected to said first output of said patient protection means for disconnecting said power-supply from said first, second and third means when the amplitude of the acting current pulses exceeds a predetermined value.
