AUTONOMOUS WEARABLE OPTICAL DEVICE AND METHOD FOR CONTINUOUS NONINVASIVE MEASUREMENT OF PHYSIOLOGICAL PARAMETERS Russian patent published in 2018 - IPC A61B5/295 A61B5/1455 

FIELD: medicine.

SUBSTANCE: method for continuous noninvasive measurement of a physiological parameter of a person is performed using an autonomous wearable optical device. At that, the first unit emits the first optical radiation to the human body to create a second optical radiation scattered from the human body. Using the second unit, the spatial changes of the spatial distribution of the intensity of the second optical radiation ordered in time are increased. Using the third unit, the temporal sequence of the spatial distribution of the intensity of the second optical radiation is determined. Using the fourth unit, the informative signal is extracted from the determined time sequence and the human physiological parameter is extracted from the said informative signal. The informative signal is a spatial informative signal comprising one or more of a spatial offset between successive spatial intensity distributions in the time sequence determined in the determining step, an angular shift between successive spatial intensity distributions in the time sequence determined in the determining step, and a scaling factor between successive spatial distributions of intensity in time sequence determined in the determining step. The wearable optical device comprises a single body enclosing completely the first, second, third and fourth units and configured to provide permanent wearing of the wearable optical device on a human body.

EFFECT: improved measurement accuracy.
