   Sphygmograph
   A sphygmograph or pulsometer was an old medical instrument for recording the movements of the arterial wall during and between the pulse beats. One of the earliest forms was invented by Marey, and consists of a lever with an elastic spring. One end of the spring is placed on the radial artery, and has above it a rack and pinion attached to a lever. The other end of the lever carries a style, which records on a moving smoked plate the movements of the vessel wall. The smoked plate is moved at a k...

It is considered the first external, non-intrusive device used to estimate blood pressure. The device was a system of levers hooked to a scale-pan in which weights were placed to determine the amount of external pressure needed to stop blood flow in the radial artery. Al...
