FIELD: medicine.
SUBSTANCE: group of inventions relates to a complex of determining arterial wall stiffness and a method of its implementation. The complex consists of a working unit 1, three sphygmocuffs with graduated hoses 2–4 and a remote processing device 6 functionally connected to them for pulse wave (PV) analysis and a user device 5 for calculating the arteriosclerosis assessment index. The working unit includes a block for filtering and converting signals 7, a block for measuring blood pressure (BP) and recording PV 8, a block for recording and storing 9, a pump block 10, a block for transmitting data to a processing device and a user device 11, a power supply unit with a battery 12. The cervical sphygmomantle is made as a Shants collar and is intended for registration of PV on the carotid artery. The shoulder cuff is designed for oscillometric measurement of brachial blood pressure. The ankle cuff is designed for both recording PV and oscillometric measurement of blood pressure at the ankle. Sphygmocuffs on the neck and ankle are pumped up to 50–60 mm Hg. Two channels of pressure change in the inflated sphygmocuffs are registered for 15–20 seconds or 5–10 heart beats. The signal received is processed and transmitted to a remote device for further processing. BP is measured simultaneously in two sphygmomandets on the shoulder and ankle, recording the data from two pressure channels. All measured and calculated data are transmitted to the user device for calculation and display of data on PV velocity, arterial wall stiffness index, and ankle-brachial index. The degree of arterial wall stiffness is determined based on the PV velocity, the arterial wall stiffness index, and the ankle-brachial index.
EFFECT: increase in the accuracy of determining the arterial stiffness index and estimating the PV rate taking into account the physiological characteristics of various sections of the arterial bed.
