APPARATUS AND METHOD FOR ESTIMATING BLOOD PRESSURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17839688 titled 'APPARATUS AND METHOD FOR ESTIMATING BLOOD PRESSURE
Simplified Explanation
The abstract describes an apparatus for estimating blood pressure using a sensor and a processor. Here are the key points:
- The apparatus includes a sensor that measures a bio-signal from an object.
- The processor obtains a cardiac output (CO) feature based on the bio-signal.
- The processor also obtains a total peripheral resistance (TPR) feature by combining the amplitude of a propagation wave component and the amplitudes of at least two reflection wave components of the bio-signal.
- The TPR feature is obtained in response to a variation of the CO feature at a blood pressure measurement time relative to a calibration time, being within a predetermined range.
- If the variation of the CO feature is not within the predetermined range, the TPR feature is obtained by combining the amplitude of the propagation wave component and an amplitude of one reflection wave component.
- The blood pressure is then estimated based on the CO feature and the TPR feature.
Potential applications of this technology:
- Medical devices for monitoring blood pressure in patients.
- Wearable devices for personal health monitoring.
- Integration into fitness trackers or smartwatches for continuous blood pressure monitoring.
Problems solved by this technology:
- Provides a non-invasive method for estimating blood pressure.
- Eliminates the need for traditional cuff-based blood pressure measurement.
- Allows for continuous monitoring of blood pressure without interrupting daily activities.
Benefits of this technology:
- Provides a more convenient and comfortable way to monitor blood pressure.
- Enables real-time monitoring of blood pressure fluctuations.
- Can help individuals with hypertension or other cardiovascular conditions to better manage their health.
Original Abstract Submitted
An apparatus for estimating blood pressure may include a sensor configured to measure a bio-signal from an object; and a processor configured to: obtain a cardiac output (CO) feature based on the bio-signal; obtain a total peripheral resistance (TPR) feature by combining an amplitude of a propagation wave component and amplitudes of at least two reflection wave components of the bio-signal, in response to a variation of the CO feature at a blood pressure measurement time relative to a calibration time, being within a predetermined range; obtain the TPR feature by combining the amplitude of the propagation wave component and an amplitude of one reflection wave component of the at least two reflection wave components, in response to the variation of the CO feature not being within the predetermined range; and estimate blood pressure based on the CO feature and the TPR feature.
