Abstract: The utility model relates to an apparatus working on the principle systole / diastole (pumping / receiving) of human blood and represents / implements a technically artificial single chambered heart which performs blood circulation outside the human body and includes a first T-junction (1) a first nozzle (1a) connected to a blood collection and returning means, a second nozzle (1b) connected via a technologically controlled mitral valve (2) and a three-way system (3) with inlet nozzle (3a) and an inlet nozzle (3b) to inlet (4a) of a chamber (4) which technically performs a systole and a diastole and directs blood through the outlet (4b) of the chamber (4) to the aortic valve (5), which passes through a pressure sensor (6) to the blood inlet (7a) of the membrane separator (7) from where through an outlet nozzle (7b) separates the plasma and from the outlet nozzle (7b) separates the purified blood which is directed to a T- junction (8) which mixes the blood with additives and directs it to a gas separator (9) via an inlet nozzle (9a) filling the separator (9), where it is monitored by means of a fluid level sensor in the gas separator (10) and through an outlet nozzle (10a) is performed a deaeration controlled by venting valve (20) and a hand clamp (28), and through the passed through micro filter for micro aggregates (11), the treated blood is directed through an outlet nozzle (9b) to a detector for presence of Type A gas (12) through a back pressure sensor (13) and a detector for presence of Type B gas (14) to a T-junction for manual deaeration (15) connected to a syringe for manual deaeration (21) and passed through a chamber (16) for the light treatment of blood (photopheresis) through a safety valve (17) and after a hand clamp (31) to a T-junction (1) through the inlet (1b), as by the separated plasma from the separator (7) and carried off through the outlet (7b) passes through a system for measurement of a volume of the separated plasma (20), and via a hand clamp (26) is directed to a collection bag and in the T-junction (8) to the purified blood are added additives through an input of an additive proportioner (19), controlled via a hand clamp (27), and to the carried off patient's blood in a three-way system (3) is added via a T-junction (3a) from a micro proportioner for an anticoagulant (22) passing through a hand clamp (29) and through a physiological saline proportioner (23) passing through a hand clamp (30) and a separable coupling (24) and are routed for connection to a T-junction (3b) for mixing additives. The apparatus which is namely the utility model performs an extracorporeal blood circulation controlled individually or in combination by the following parameters: cyclic operating mode "systole / diastole" based on predetermined pressure or predetermined volume or predetermined volumetric speed / flow rate of blood flow, or cyclic "systole / diastole" operating mode based on a pre-set operating cycle time, and / or extracorporeal processing of blood cells and blood polypeptides with a light source with controllable length and intensity of radiation. In this case, the apparatus is provided with a control computer. Preferably, controllable valves (2, 5, 17) are executed as an isolation plate, mounted on anchor of an electromagnet, capable of interrupting simultaneously up to three pipelines, and the controllable deaerating valve (20) at the outlet of the gas separator (9) is from rotating electromagnet type with a compression spring and with the possibility of manual propulsion, wherein a valve (2) on the bloodstream acts as a "mitral" heart valve and interrupts the flow of untreated blood to the chamber of the pump (4), the buffered saline and the anticoagulant, the second valve (5) acts as an "aortic" heart valve and interrupts the flow from the chamber of the pump (4) to the filter of the membrane separator (7) and the third valve (17) is protected and is triggered only in the presence of gas behind the last gas sensor (14) in the pipe system.
