Název v původním jazyce

Method for an accurate automated non-invasive measurement of blood pressure waveform and apparatus to carry out the same

Popis výsledku v původním jazyce

An apparatus for an accurate automated non-invasive measurement of blood pressure waveform using brachial (occlusion) cuff pressurized above systolic pressure and using differential pressure sensor. The methodology involves measurement in suprasystolic mode and in utilization and construction of the device followed by algorithms for processing and analysis of measured blood pressure pulse waves and assessment of hemodynamic parameters of human cardiovascular system. The device includes an electro-pump connected to the collar device, a differential pressure sensor, pressure senor A, pressure sensor B, valve, closing a valve and the air reservoir. The cuff is wrapped around a person's arm. The values of the instantaneous pressure in the pneumatic portion of the device are converted into an electric signal by the pressure sensor A, pressure sensor B and the differential pressure sensor. These signals are then filtered using a set of passive RC elements for filtering out high frequency interference, and fed to the microprocessor with a computing unit, analog to digital converter. The sampling frequency is sensed signal at least 200 Hz. The control algorithm in the microprocessor, according to signals from the pressure sensor A further controls the course of cuff pressurization, controls the control valve, and finally determines the closing and opening of the closing valve. A microprocessor further controls a display and the data may be transmitted to the PC. ### The patent is exploited by its owner.
