CONTINUOUS TRANSDERMAL MONITORING SYSTEM AND METHOD

摘要

Various embodiments of methods and systems for continuous transdermal monitoring (“CTM”) are disclosed. One exemplary method for CTM begins by monitoring an output signal from an accelerometer. The accelerometer output signal may indicate acceleration and deceleration of a body part of a user, such as the user's wrist. Based on the accelerometer output signal, it may be determined that the body part of the user has decelerated to a minimum, e.g., substantially zero. With a determination that the body part has decelerated to the minimum, e.g., substantially zero, or has not accelerated beyond the minimum, e.g., substantially zero, the method may determine a reading from a pulse oximeter associated with the accelerometer. Advantageously, the pulse oximetry reading, or a reading from other sensors associated with the accelerometer, may be optimally accurate as motion artifact may be minimized. The pulse oximetry reading may be recorded for later query and/or rendered for the benefit of the user.

主权项

1. A method for minimizing the effects of motion artifact on sensor readings taken during continuous transdermal monitoring of a body part in motion, the method comprising:
monitoring, with a processor, an output signal from an accelerometer, wherein the output signal indicates acceleration and deceleration of the body part of a user as the body part is in motion; determining, with the processor, from the output signal that the body part of the user has decelerated to a predetermined minimum before becoming momentarily stationary to begin acceleration; based on the determination that the body part of the user has decelerated to the predetermined minimum, determining, with the processor, a plurality of readings from a sensor, wherein determining the plurality of readings from the sensor occurs over a time window that includes the body part of the user becoming momentarily stationary; and recording in a memory device the determined plurality of readings from the sensor.
