A "Simplitrol Portable Model Cambridge Electrocardiograph" in a wooden carrying case, manufactured by Cambridge Instrument Co. for the Ohio Institute for Medical Assistants. This is a string galvanometer type electrocardiograph. The mahogany case has a steel handle and two hoop-spring locks on the front side of the case which folds down for access. A brass nameplate gives the name of the instrument and manufacturer, and the model or serial number for the machine. The case has three fitted compartments, two metal and one wood. It has a mounted camera and a heavily insulated outlet cord and electric plug. The plug has a rubber cover marked "RA, LL, P, LA" for right arm, left leg, pulse, and left arm. Numerous loose instrument pieces include: 1) four electrodes, 2) three metal plates with terminal screws, measuring 3.7 x 6 cm, 3) grooved circular metal plate with hard rubber insulated handle and terminal screw, 4) one cartridge of No. 30 Canco photographic paper, 5) removable metal drum, for receiving the exposed film, 6) electrocardiograph lamp bulb, 2A-14V, marked with date and manufacturer "1933 GE," 7) rubber-insulated electric cord with on/off switch, 8) silk-covered jump cord with an alligator clip in a rubber handle at one end and a terminal clip at the other, 9) three small envelopes, containing a blown fuse, a perforated red rubber strip, three black perforated plastic strips, a tube of Cambridge Electric jelly, and a flat black plastic reel. The case and permanent fittings are in good condition. Rubber and plastic parts have hardened and the photographic paper has stiffened. Some parts show corrosion. The case key is missing.
Digital photograph of a "Simplitrol Portable Model Cambridge Electrocardiograph," a 1930's-era string galvanometer type electrocardiograph. The instrument is shown in its original mahogany carrying case. Three small envelopes containing parts have been propped against the front of the case. A ruler has been placed in the foreground for size comparison.
