FIELD: medicine.SUBSTANCE: artificial ventricle of the heart comprising a two-stage diaphragm pump and a cannula consisting of ventricular and aortal portions series connected to the pump; the pump consists of a membrane-divided gas cylinder, which is piped or canalled to a device providing pulsed gas feed alternated with vacuum generation; a pumped medium chamber is provided with a union to connect to the ventricular portion of the cannula; the ventricular portion represents a rigid tubular element perforated along the periphery of its diametric section configured between retainer washers in an inner wall of the tubular element of the cannula and displaced towards the retainer washer remote from the union of the diaphragm pump; a cylindrical cup is less high than a distance of the retainer washers and has a base hole; the base is provided in the inner portion of the tubular element of the cannula and movable between the retainer washers to open and close the perforations, while the aortal portion of the cannula is made of a soft silicone tube. Disclosed is a version of the artificial ventricle characterised by structural implementation.EFFECT: invention enables the heart unloading to recover the myocardial function and to maintain blood pressure in the circulatory system.10 cl, 3 dwg, 2 ex |
