Recklinghausen Tonometer (sphygmomanometer), Germany, 1915-1925
This tonometer is a type of sphygmomanometer. A sphygmomanometer
measured the force, rate and variations in the pulse. The
tonometer consists of two overlapping cuffs. It measures the
systolic and diastolic blood pressure. This means the force that
blood flows with from the heart into the arteries and the forces
as the heart relaxes and fills again with blood. It is the
commonest technique for measuring blood pressure. It is also
completely safe. This device was developed by Heinrich von
Recklinghausen (1867-1942) in the 1920s. He was a leading
researcher in blood pressure and blood pressure measurement.
