Application: Arterial-pressure estimation apparatus, arterial-pressure estimation system, and arterial-pressure estimation method (Patent ID: US20230355116A1)
The patent filed by Terumo Corp. describes an arterial-pressure estimation apparatus that acquires sensor data indicating blood flow timing in a blood vessel downstream of the aorta, records corresponding pressure values, corrects pressure values during inspiration periods, and estimates arterial pressure changes over time. The apparatus can perform weighting based on elapsed time in the inspiration period, set weighting coefficients using invasive examination data, and match pressure reduction timing with the respiration cycle. It can also estimate left ventricular end-diastolic pressure (LVEDP) and generate trained models for LVEDP estimation through machine learning.
Furthermore, the patent includes claims for an arterial-pressure estimation system with a sensor for blood flow detection and an inflation portion for compression, as well as a method for estimating arterial pressure by compressing blood vessels, detecting blood flow, recording pressure values, correcting values during inspiration periods, and estimating pressure changes over time. The method can involve weighting based on inspiration period time, setting weighting coefficients using invasive examination data, and matching pressure reduction timing with the respiration cycle. Additionally, a computer-readable medium storing a program for executing the arterial-pressure estimation process is also claimed in the patent.
