Researchers Submit Patent Application, 'Sensor Device and Method for Measuring and Determining a Pulse Arrival Time (Pat) Value', for Approval

摘要

"Nowadays techniques that allow assessing PWV non-invasively fall into two main categories. On the one hand, COMPLIOR (Colson, France), SphygmoCor (AtCor Medical, Australia), Vicorder (Skidmore Medical, UK) and PulsePen (Diatecne, Italy) rely on the placement of two pressure transducers onto two superficial arteries. These devices detect the arrival time of a pressure pulse that propagates through the arterial tree, and calculate the delay in pulse arrival times between the proximal and distal sensors. By approximately measuring the distance through which the pulse has propagated, one estimates then a pulse propagation velocity value. Large clinical studies support the reliability and clinical validity of this technique.
