Apparatus for detecting and indicating electrical body potentials

Abstract

Abstract A device for measuring the potential across two points on the human body, comprising a box-like structure having distinct side walls, one of which includes the screen of a cathode ray tube. On each of first and second adjoining side walls of the box-like structure there are two spaced body-contacting electrodes adapted to be pressed against a human body to measure the potential across the two points on the human body corresponding to the position of said electrodes thereon. The box-like structure includes internal circuitry of a type well known in the prior art for measuring the potential between said electrodes and displaying the same on said cathode ray tube. The two electrodes on one face of the box wrapped around an edge of the box to thus form electrodes on another face, so that the box-like structure can be placed in either of two positions on the human body, to give two viewing positions for the cathode ray tube. One of said two faces of the box is opposite to the end of the box which includes the screen of the cathode ray tube. A strap is provided whereby the box-like structure can be strapped to the human body, with one of said electrode-carrying side walls in intimate contact with the body, so that a continuous reading can be easily taken.
