[Automatic regulator of venous pressure and venous outflow in the perfusion system].

A scheme for automatic regulation of the venous pressure and venous blood outflow during extracorporeal circulation is proposed. The system consists of a photoelectric sensor placed on a tube led out of the major venous trunkline, a converter and an electromechanical eccentric clamp that compresses the venous trunkline, all of which secures stabilization of the controlled values.

[The technical requirements of simulating cardioplegia and perfusion of an isolated heart].

A testing unit for simulating cardioplegia and restorative perfusion of an isolated heart is described. The testing unit is fitted out with a chamber for an isolated heart, an oxygenator, a heat exchanger, the perfusion system and organs controlling heart work under different conditions of perfusion and cardioplegia. The system approximates the physiological condition of the experiment and allows changing and controlling them on a broad enough scale.

[A device for complete and assisted artificial circulation].

The authors describe a system for complete and auxiliary extracorporeal circulation (EC), manufactured on the basis of elements of industrial pneumoautomatics in the form of blocks controlling venous and arterial blood flows. The venous part regulates the venous inflow volume by the feedback type mechanism; the arterial part ensures complete EC in the pulsating mode during cardiosurgical intervention and auxiliary EC in the course of heart activity recovery after cardioplegia, promoting an increase of the coronary blood flow and synchronized blood supply.
