<p>An artificial lung which has a plurality of flexible and resilient small diameter tubes constructed of a gas pervious material and extending in a generally upright direction through a surrounding housing. An oxygen transferring medium is in the housing for the transfer of oxygen to the blood and withdrawal of carbon dioxide from the blood. Blood entering the housing is cooled to facilitate the oxygen absorption and is warmed to body temperature before exiting the housing. The pressure of the fluid in the housing is pulsed and appropriate check valve means are inserted in the blood stream at the blood intake and outlet to induce a cyclical, heart-like blood flow through the compression and expansion of the flexible tubes.</p> |
