Abstract
An artificial lung for humans and other mammals inserted within the body or placed externally. The artificial lung comprises an electrically actuated three-way valve, a casing containing parallel loops of oxygenator tubes for oxygenation of blood by an atmosphere of circulating air, and an air circulation driving fan powered by an energizing system. As a safety factor in the event of leakage in the casing, a check valve is inserted in an effluent blood duct from the casing to the aerated effluent blood. Two artificial lungs can be utilized internally as left and right lungs.
Claims10
An artificial lung device comprising:
- a cylindrical metal or plastic casing containing parallel loops of oxygenator tubes for flowing blood separated by a spacing;
- said spacing providing circulation of air;
- a miniature enclosed fan for exhausting effluent air from said casing and intake of fresh air to said casing;
- and
- an electrically actuated three-way valve connected to the trachea by a tube and a coupling, and receiving the effluent air from the fan, and a tube from the electrically actuated three-way valve feeding fresh air to the casing;
- said casing, fan and electrically actuated three-way valve encased in a liquid-proof bag for insertion within a mammalian body or positioned outside the body for oxygenation of blood and returning said blood to the mammalian body.
