Low-power, compact, resilient system and method for physiological monitoring

摘要

A monitor of a physiological parameter of subject under test to which the monitor is attached, in operation. The monitor includes a set of accelerometers operating in different ranges of acceleration and a physiological sensor. The physiological sensor may include an ECG circuit producing an output data characterizing the subject as a function of a degree of motion and/or reorientation of the monitor or an oximeter device. The process of monitoring includes a determination of R-wave of the subject.

主权项

1. An article of manufacture, comprising:
a monitor unit including, on a single integrated board, motion sensors configured to collect first data, representing orientation and motion of the article, simultaneously in multiple ranges of acceleration, wherein a motion sensor is configured to generate a first output, a physiological sensor enabled to collect second data representing a physiological parameter and generate a second output, a data-logging unit including tangible non-transitory storage medium, a controller in operable communication with said motion sensor and the physiological sensor, the controller configured to receive the first and second outputs and route data associated with at least one of the first and second outputs to said data-logging unit, a clocking device connected to the controller and configured (i) to produce a time stamp that is associated with a) said received at least one of the first and second outputs and b) synchronization data, and that is configured as a reference for time-alignment of data received from multiple sensors, and (ii) to activate said monitor unit without an input from the user; and an electrically-conducting lead electrically connected to a port of the monitor unit.
