Enhanced stethoscope device and method for blood pressure measurement via plurality of ultrasound transducers and optical sensors to determine time series blood values using autoencoders

An enhanced stethoscope device comprising:

• a first ultrasonic transducer for transmitting a first ultrasonic imaging signal to a blood vessel of a subject and receiving a second ultrasonic imaging signal from the blood vessel;
• a second ultrasonic transducer for transmitting a third ultrasonic imaging signal to the blood vessel and receiving a fourth ultrasonic imaging signal from the blood vessel;
• and
• an optic sensor directed toward the blood vessel;
• wherein the blood pressure measurement device is configured to:
• reconstruct, using the second ultrasonic imaging signal and the fourth ultrasonic imaging signal, an ultrasonic image;
• obtain a first time series of sensor values associated with one or more signals received by the first ultrasonic transducer;
• obtain a second time series of sensor values associated with one or more signals received by the second ultrasonic transducer;
• obtain a third time series of sensor values associated with one or more signals received by the optic sensor;
• pass the first time series of sensor values, the second time series of sensor values, and the third time series of sensor values to an autoencoder;
• determine, based at least on the first time series of sensor values, the second time series of sensor values, and the third time series of sensor values, using the autoencoder, a physiometric parameter associated with the subject;
• and
• correlate the second ultrasonic imaging signal received from the blood vessel and a first optical signal received from the blood vessel to determine a blood pressure,
• wherein a first velocity measurement of a blood bolus in the blood vessel is obtained using the first ultrasonic transducer and the second ultrasonic transducer, and a second velocity measurement of the blood bolus in the blood vessel is obtained by the optic sensor.
