In one embodiment of the invention, a cuff-less blood pressure measuring system is disclosed including cuff-less blood pressure scanner with a vital signs signal processor having an adaptive blood pressure model. A machine learning process is further disclosed to tune the adaptive blood pressure model of the cuff-less blood pressure measuring system to the user.

Cuff-less multi-sensor system for statistical inference of blood pressure with progressive learning/tuning

A blood pressure monitoring device includes a body portion having a size and structure to extend around an appendage of a user during use, a fluid bladder at least one of attached to or integral with the body portion and arranged to be able to apply pressure to an adjacent artery or vein of the user during use, a pressure actuator fluidly connected to the fluid bladder, a controller configured to provide control signals to the pressure actuator to fill the fluid bladder to selected pressures, a signal processor configured to communicate with the controller to receive signals indicating the selected pressures to which the fluid bladder is filled, and a pressure sensor arranged in operative contact with the fluid bladder to measure blood pressure waveforms plus bladder fluid pressure to provide a pressure waveform signal containing information regarding a relationship between vessel distention and transmural pressure. The pressure sensor is further configured to communicate with the signal processor to provide the pressure waveform signal to the signal processor. The controller is configured to provide a plurality of selected pressures that are less than a mean arterial pressure of the user, and the signal processor is configured to calculate blood pressure parameters using pressure waveform signals produced during application of the plurality of selected pressures that are less than the mean arterial pressure of the user.
