Apparatus for measuring the human being's blood pressure.

摘要

This process consists in measuring the blood pressure at the tip of a finger by compressing a portion of the finger with a blocking device (5), in progressively reducing this pressure with a controllable release valve (10) and in measuring the pressure evolution by a transducer (11). Parallelwise, an optical-electronic detector (1) applied against the skin at a pressure of between 50 and 100 g/cm<2> measures the average transparency evolution of the tissues in a portion of the finger located downstream with regard to the blocking zone. Pressure values characteristic of the average transparency curve are detected in an amplifier circuit (12) and treated in an analog-digital converter (13) and a computing element (14).
