Electro-Metabograph Device

The Electro-Metabograph Cardio Tachovolumeter, also referred to simply as the Electro-Metabograph Device, is an electro-mechanical device that was sold for use in electronic medicine by Art Tool & Die Co., Detroit, Michigan-based manufacturers. A U.S. Food and Drug Administration (FDA) seizure notice described the apparatus as "a three-paneled, desk-type console unit" with the panels having "a variety of push buttons, switches, dials, meters, and a photoelectric cell," one of these panels being "an oscilloscope and controls," and, in addition to the panels, a "small metal well" for placing blood samples on the desk surface, as well as an attached "probe-type electrode" that was to be used for "locating pinched nerves."
