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 the doctor offices and operating rooms of today. Some equipment may be recognizable, while other inventions featured here have since become obsolete or have had their usefulness discredited.
