METHODS, SYSTEMS, AND DEVICES FOR OPTIMUM POSITIONING OF SENSORS Russian patent published in 2019 - IPC A61B5/04 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine and can be used to determine optimum positioning of a sensor for measuring a physiological parameter of a user. Body of a biomedical sensor has a skin-facing surface and an opposite surface. Biomedical sensor has conducting elements, a sensing element, an indicator, a processor, a storage device and a motion sensor. Conducting elements are located on the skin-facing surface, and are connected to the sensing element. Indicator is located at a distance from the skin-facing surface. Processor is connected to the sensing element, indicator and storage device so that it determines the quality of sensor positioning by comparing the measured signal with a stored physiological model and controls the indicator to provide a certain quality sensed by a person. Processor is configured to record motion data from the motion sensor, compare the recorded data with the stored motion model corresponding to the selected position on the body, and provide an indication of the comparison result which can be read by the person. Method includes a calibration step of using a sensor to measure a physiological parameter of the body, automatic measurement of an acceptance criterion using the processor, a test step where a sensor provides a test measurement, automatic determination of whether the test measurement corresponds to the acceptance criterion of the measurement obtained at the measurement step, and automatic use of the indicator of the sensor to provide an indication of the results of the determination step which can be read by the person. Biomedical sensor of the system for determining the optimum positioning of a sensor includes a first transceiver. User interface device of the system includes a second receiver-transmitter. System processor is connected to the user interface device and is configured to automatically determine, using the received measurement data, whether the position of the sensor on the body corresponds to the selected acceptance criterion at a moment in time corresponding to the execution of the received measurement, and if this condition is not met, provide user feedback on the sensor position by means of user interface device.

EFFECT: enabling identification of optimum conditions for use of a sensor (quality of positioning and location) by using two different sensors and comparing their signals with two stored models.
