ABSTRACT:
The invention relates to a method for the non-invasive measurement of the internal pressure of elastic vessels, according to which a restoring force is detected on the outer surface of the vessel and the internal pressure is determined from the measured force and the relaxation curve of the vessel. The aim of the invention is to be able to measure internal pressure in a simply yet highly accurate manner. To this end the relaxation curve is determined repeatedly after the start of the measurement.
