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. The picture and description appear courtesy of Dr. M. Donald Blaufox, M.D., Ph.D., from his website: www.mohma.org.
