Application: Non-invasive blood pressure measurement using pulse wave velocity (Patent ID: US20240206746A1)
The patent filed by Stryker Corp. discloses a method and apparatus for non-invasively measuring instantaneous blood pressure using pulse wave velocity. The system includes a measurement component with sensors, such as an ultrasound sensor, affixed to a patient near a blood vessel. The sensors measure pulse wave velocity and blood velocity within the vessel simultaneously, allowing for the computation of instantaneous blood pressure using the water hammer equation. The sensors can be integrated into a disposable patch or collocated with other sensors like those found in patient-monitor devices.
The patent further details a vital sign monitor and a medical device incorporating ultrasound and optical elements to detect reflections from a blood vessel and analyze them to determine pulse wave velocity, blood velocity, and ultimately the blood pressure of the subject. The processor in the device calculates these parameters based on the movement of the vessel wall, time intervals, and phase differences between ultrasound reflections. The output device, which can be a display screen or speaker, provides an indication of the subject's blood pressure. Additionally, the method outlined in the patent involves transmitting ultrasound and optical signals towards the blood vessel, analyzing reflections, and determining blood pressure based on pulse wave velocity and blood velocity calculations. The method also includes determining the distance between the device and the vessel, as well as outputting data indicating the subject's blood pressure.
