DEVICE EXAMINING REGIONAL BLOOD-FILLING AND LUNGS VENTILATION Russian patent published in 2002 - IPC

FIELD: medicine, examination of disturbances in blood-filling and lungs ventilation. SUBSTANCE: device has controlled high-frequency generator, radiator, matrix of pickups which is installed opposite rear surface of thorax, detector, analog-to-digital converter, unit recording measured data, two multiplexers and two feedback channels. Each feedback channel incorporates recorder, digital-to-analog converter and amplifier. Outputs of amplifiers are connected to inputs controlling frequency and amplitude of signal of generator. Recorder of measured data is built on elements which present data in the form of breathing curves changing in time and evaluation of blood-filling and ventilation per each of six regions of lungs is carried out. Device displays expanded functions making it possible to determine both regional blood-filling and regional ventilation of lungs and demonstrates high degree of authenticity of obtained data. EFFECT: increased informativity and accuracy of obtained data. 6 cl, 9 dwg
