METHOD OF CONTROLLING CARDIO-PULMONARY RESUSCITATION AND DEVICE FOR ITS REALISATION Russian patent published in 2015 - IPC A61B5/205 A61B8/06 A61B5/53 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to means for performing cardio-pulmonary resuscitation of people. Device for control of cardio-pulmonary resuscitation contains ultrasound converter, unit of electrodes, connected via interface to processor, connected with display, memory unit, sound signaller, unit of light-diode signallers, unit of connection with central control panel unit of operation mode selection, unit of connection with the internet and, via USB interface, with unit of top level software. Device also contains colour television microcamera, connected via successively installed block of signal amplification and filtration and unit of processing and imposing alignment of images to additional processor input/output, illumination unit, pulse measurement unit, gas analyser, unit of microphones with matching unit, connected with processor and power supply unit. Pulse measurement unit and unit of electrodes are made with possibility of fixation on patient by means of fixation unit, with unit of microphones, controlled illumination unit and gas analyser being fixed on patient by means of additional fixation unit. Method of control contains stages of obtaining ultrasound echo signals and electrosignals, characterising blood flow in blood vessel, determination of blood flow characteristic by impedance of neck tissues in the process of performing cardio-pulmonary resuscitation, presentation of sound and visual information about patient/s condition. After that, current information about patient's condition is formed by television images and geometrical and colour characteristics of eye pupil and eye iris are determined, with estimation of colour and geometrical characteristics of blood vessels. Sound laryngeal signals, exhaled gas and patient's pulse are also read and analysed, light signals are used to signal about patient/s condition and patients condition is estimated basing on data of comparison of standard and current information.

EFFECT: application of invention makes it possible to extend functional possibilities, increase operation speed, immediacy and accuracy in performing cardiopulmonary resuscitation.
