FIELD: medical engineering. ^ SUBSTANCE: device has two-sectioned chamber having inlet and outlet section manufactured from transparent material. The chamber has internal canal repeating heart cavity or aorta shape and place for implanting the valve. Openings are available in chamber section walls having metal wires and nipples fixed and sealed in them. The outlet chamber section has optical window in its end and tap holding mounted electrode. Cavity is available at the place the sections are connected to each other for fixing and sealing the valve allowing its rotation. The device has pulse generator, time shift source, system for control blood circulation phantom, frequency meter unit, illumination system, pressure and flow sensors. Generator inlet is connected to the system for control blood circulation phantom via the time shift source, the first generator outlet is connected to metal wires and electrode and the second one to the frequency meter unit. The illumination system is mounted on the chamber. Pressure sensor is connected to chamber sections by means of plastic mains via the nipples. The flow sensor is mounted in outlet section tap. ^ EFFECT: enhanced effectiveness in visualizing model liquid flow in heart valve and determining large shift stress zones. ^ 2 dwg |
