Each month, we visit Dr. Blaufox’s Museum of Historical Medical Artifacts to take a look back at the medical equipment that cleared the way for what patients encounter in doctors’ offices and operating rooms of today. Some equipment may be recognizable, while other featured inventions have since become obsolete or have had their usefulness discredited.

A 7” high x 6” diameter drum sits on a very heavy cast iron stand. A 3.5” x 2” x 1.25” brass box contains the gear mechanism. There is a winding key and a flywheel. The drum turns a gear at the device’s bottom that is connected to a gear on the box bottom with a replacement O-ring. On one leg is a rod with adjustable connectors and two air-actuated diaphragms with original needles to attach to a physiologic recording device. Additional recording devices could be attached to broaden its range of measurements.
