DEVICE FOR DISTANCE REGISTRATION OF PROCESSES OF PATIENT'S HEART BEATS AND RESPIRATION Russian patent published in 2013 - IPC A61B5/205 A61B8/02 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment and can be used in medical practice for distant registration of processes of patient's respiration and heart activity in real time. Device for distant registration of processes of patient's heart beats and respiration contains successively connected generator of harmonic fluctuations, power amplifier and irradiator in transmitting part, and narrow-band amplifier, measurer of phase shift and unit of separation of respiration and pulse constituents in receiving part. In transmitting part device is provided with second generator of harmonic fluctuations of another frequency and adder of signals of both generators, switched to irradiator, which simultaneously is receiver of reflected signal via key and power amplifier. In receiving part device is provided with first detector and in transmitting part with successively connected second detector, first extremator and gate former. In receiving part device is also provided with measurer of temporary intervals.

EFFECT: application of the invention will make it possible to increase sensitivity and noise immunity.
