FIELD: medicine. ^ SUBSTANCE: invention relates to medicine, namely can be applied to obtain information about state of cardio-vascular system. Method of diagnostics and measurement lies in picking up parametres of pulse wave movement, registered on the surface of integument in zone of carotid and radial arteries outlet by means of microstrip lines. In phase detector changes of signal parametres on the microstrip line outlet are detected. After that signal is amplified, its analogue-digital transformation and primary processing in microcontroller are carried out. Signal is passed into system of signal processing and visualisation to diagnose cardiac rhythm, pulse wave rate, and to form report in order to present values of measured pulse wave parametres. Measuring device contains devices of first and second sensors connected by means of connective link - cable. Devices of first and second sensors include: probing pulse generator, microstrip line, phase detector, differential drive, tool storage, analogue adder. Device of first sensor additionally contains quartz generator. Device of second sensor additionally contains analogue-digital converter. Measuring device also contains microcontroller and unit of wireless signal transmission to external device of signal processing and visualisation. ^ EFFECT: application of invention allows to increase versatility of carrying out pulse wave measurement. ^ 6 cl, 6 dwg |
