METHOD TO ASSESS HEMODYNAMICS OF EXTRACRANIAL SECTION OF INTERNAL CAROTID ARTERY IN EXPERIMENT AND DEVICE FOR METHOD REALISATION Russian patent published in 2011 - IPC G09B23/28 A61B17/00 A61B5/02 

FIELD: medicine.

SUBSTANCE: oral diaphragm is cut at the level of 1-2 molars in a deceased. Cannulation of artery ends is made. Bifurcation tubes are inserted into artery ends. One end of each bifurcation tube is connected to differential manometer, and the second end of the first bifurcation tube is connected to pump. The second end of the second bifurcation tube is placed into metering vessel with liquid, and liquid is pumped with simultaneous measurement of pressure gradient and volume speed of liquid flow. Device for method realisation includes metering reservoir with liquid, pump of submersible type arranged in reservoir, head and discharge flexible pipelines, and also differential manometer and two bifurcation tubes. At the same time the first ends of each bifurcation tube are connected to differential manometer. Head pipeline is connected to pump of submersible type and with the second end of the first bifurcation tube, and drain pipeline is connected to the second end of the second bifurcation tube.

EFFECT: invention increases validity of produced hemodynamic parameters.
