DEVICE FOR REMOTE OBSERVATION OVER PATIENTS' STATE Russian patent published in 2009 - IPC A61B5/205 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, in particular to diagnostic devices, and can be applied for remote observation of several patients simultaneously and immediate production of alarm signal in case of aggravation of observed patients' state. Device for remote observation of patients' state contains central control panel, consisting of ECM with devices of: input and information display respectively, receiver and transmitter of electromagnetic signal and registers of biological parametres, placed on patients. Registers include sensors of patient's physiological parametres, unit of information transformation, transmitter of electromagnetic signal, control unit, autonomous power source. Unit of information transformation contains commutator analogue-digital converter and coder. Control unit contains decoder, circuits of code comparison, memory unit of control codes storage, time delay unit and OR circuit. Each transmitter contains master clock, phase manipulator, first mixer, first oscillator, amplifier of first intermediate frequency, power amplifier. Each receiver contains amplifier of high frequency, first narrow-band filter, first phase inverter, first adder, second band filter, second phase inverter, second adder, third band filter, third phase inverter, third adder, second oscillator, second mixer, first amplifier of second intermediate frequency, first phase changer on 90°, second amplifier of second intermediate frequency, second phase changer on 90°, fourth adder, second multiplier, second narrow-band filter, amplitude detector, key, first multiplier, first band filter and phase detector.

EFFECT: invention ensures increase of receiver selectivity and noise-immunity due to suppression of false signals (noise) received on additional channels.
