1. A blood-gas exchange device comprising:
a. a first chamber comprising at least: a gas inlet and a blood inlet for insertion of blood and gas into the blood-gas exchange device for oxygenating the blood and/or for removing carbon dioxide from the blood;
b. a second chamber comprising at least: a blood exit for delivering the oxygenated and/or decarbonated blood out from the blood-gas exchange device, and a gas exit configured to allow flow of gases out from the blood-gas exchange device into the surrounding; and
c. a rotatable chamber connected to said first and second chambers, said rotatable chamber comprising at least:
a) a blood channeling element configured to direct the inserted blood to flow on the walls of the rotatable chamber through at least one set of opening and/or semi-openings;
b) at least one gas opening configured to allow flow of the inserted gas from said first chamber into said rotatable chamber toward the flowing blood, and at least one gas opening configure to allow gas flow from the rotatable chamber to the second chamber; and
c) a motor configured to spin said rotatable chamber;
wherein, the circular movement of the rotatable chamber channels the blood to flow along the rotatable chamber walls, forming a blood layer on the wall that directly contacts with the gas and allows gas exchange.
