DEVICE AND METHOD FOR INDUCTIVE READING FOR NON-INVASIVE MEASUREMENT OF MECHANICAL ACTIVITY OF PATIENT'S HEART AND LUNGS Russian patent published in 2023 - IPC A61B5/05 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, namely to non-invasive study of such physiological characteristics as patient’s heart and lungs dynamics. A method for inductive reading for non-invasive measurement of mechanical activity of heart and lungs is implemented using an inductive reading device. The device contains a resonator circuit formed by the first loop part connected to a capacitor, the second loop part, current-conductive lines, and an active buffer component. The first and the second loop parts are formed by current-conductive lines and spaced from each other in a radial direction along sections of current-conductive lines. The active buffer component electrically connects an output of the resonator circuit to the second loop part and provides amplification of current voltage. An output signal of the active buffer component excites alternating current in the second loop part. The first and the second loop parts are located so that an average radial distance between current-conductive lines is not less than a distance between the second loop part and an area in contact with patient’s tissue.

EFFECT: reduction in sensitivity to motion artefacts and, respectively, sensitivity of a device to movement without an additional complicated circuit and a low catching force.
