US 2026/0076641 A1 · DEVICE AND METHOD FOR CONTINUOUS, NON-INVASIVE BLOOD PRESSURE MONITORING

Abstract

A continuous, non-invasive, blood pressure monitoring system for determining a blood pressure measurement for a wearer is provided. The system has accuracy close to that of an invasive catheter transducer system for continuous blood pressure measurement. The system includes an ultrasonic sensor patch, a processor, and a memory. The patch includes an ultrasonic transducer located externally on a body part of the wearer and in a vicinity of a vessel that is configured to determine a diameter of the vessel. The patch also includes a power component. Further, the memory includes instructions that, when executed by the processor, cause the system to calculate a cuffless blood pressure measurement for the wearer based on the diameter of the vessel as determined by the transducer and transmit the cuffless blood pressure measurement to a host computer via a network. A method for continuous, non-invasive, blood pressure measurement is also provided.
