A heart-lung machine includes a tubing set and has tube loops for supplying to an artery, and extraction from a vein. The unit also includes an oxygenator, blood pump and oxygen dispenser. An oxygen concentrator (1) dispenses oxygen and has a connected pump (8) drive, with electrical connection (2) supplied from a decentralised supply of electricity having a second connection (4) for a battery. Preferably polytetrafluoroethylene is used as the flexible material in the pump region. Membrane filter separation is used for oxygen recovery with a plate oxygenator (plastic lung) and filter forming part of the circuit. |
