Dobrova V. Methods and devices for the control of blood pressure variations

The dissertation is devoted to the task of increasing the reliabi- lity of control of blood pressure variations by means of creation of new devices and methods for these signals processing. The model of skin cover element motion under influence of blood pressure is proposed. On its basis the dynamic characteristics of the "voronka" and cuff are considered. The dynamic characteristic of pneumatract is studied. The active receiver and compensating pneumatract are designed. The modified oscillatory system with quartz resonator that is modulated by the interelectrode clearance and correcting element are proposed. The spectral method of blood pressure variations estimations of form-time parameters is proposed. The model of arterial channel sections as digital filter are investigated. The measuring channel and multichannel pulse- metric system are designed and realized practically.
