ESTIMATING CENTRAL BLOOD PRESSURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18028225 titled 'ESTIMATING CENTRAL BLOOD PRESSURE
Simplified Explanation
The patent application describes a device that can estimate the central blood pressure of a person.
- The device includes a sensor patch with multiple sensors that can measure the blood pressure of a peripheral blood vessel and perform ultrasound imaging of the vessel.
- A processor in the device processes the signals from the sensor patch to obtain a pressure waveform and an image of the peripheral blood vessel.
- The processor then determines the diameter of the vessel over time, creating a vessel diameter waveform.
- Using the pressure waveform and/or the vessel diameter waveform, the device can estimate the central blood pressure of the person.
Original Abstract Submitted
A device is for estimating the central blood pressure of a subject. The device comprises a sensor patch comprising an array of sensors configured to measure an indication of the blood pressure of a peripheral blood vessel and perform ultrasound imaging of the peripheral blood vessel. The device also comprises a processor configured to obtain a peripheral pressure signal comprising a pressure waveform from the indication of the blood pressure from the sensor patch and derive an image of the peripheral blood vessel from the signals received from the sensor patch. A vessel diameter is determined from the image of the peripheral blood vessel over time comprising a vessel diameter waveform and an estimate of the central blood pressure of the subject is derived from the pressure waveform and/or the vessel diameter waveform.
