1. A blood-gas exchange device comprising:
a. a stationary blood collecting tank, said stationary blood collecting tank surrounds at least part of a rotating tank, and comprises at least a gas inlet configured to allow flow of gas into the blood-gas exchange device, a gas exit configured to allow exit of gas out from the blood-gas exchange device; and a blood exit configured to allow flow of oxygenated and/or decarbonated blood out from the blood-gas exchange device into a tube;
b. a rotating tank, said rotating tank comprises at least: a gas inlet and a blood inlet for insertion of blood and gas flow into the blood-gas exchange device for oxygenating the inserted blood and/or for removing carbon dioxide from the inserted blood; and at least one blood exit opening for removing the oxygenated and/or decarbonated blood out from the rotating tank into the stationary collecting tank; and
c. a motor configured to spin said rotating tank;
wherein, the circular movement of the rotating tank channels the inserted blood to flow along the rotatable tank wall from bottom to top, forming a blood layer on the wall that directly contacts with the gas and allows gas exchange; and
wherein the stationary blood collecting tank is assembled with the rotating tank in a manner that the oxygenated and/or decarbonated blood that exit from the rotating tank through said at least one exit opening is being spilled into the stationary collecting tank and gathered to flow into a tube.
