Who introduced the device using an arm cuff around 1896 for non-invasive measurement?

Scipione Riva-Rocci

The development of the manual sphygmomanometer, the essential instrument employing an inflatable cuff for non-invasive blood pressure assessment, is largely credited to Scipione Riva-Rocci. He introduced his device around the year 1896. This early apparatus was clinically focused, cumbersome, and demanded that a trained physician listen using a stethoscope to detect specific arterial sounds as the cuff pressure was slowly released. Although purely a clinical tool at that stage, this invention established the fundamental principle required for all subsequent measurements: the reliable occlusion and subsequent slow release of pressure to derive systolic and diastolic readings, setting the baseline for future miniaturization efforts.
