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.

Claims

1. 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 structured and arranged for connection 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 is encased in a liquid-proof bag that is structured and arranged for insertion within a mammalian body or is positioned outside the mammalian body for oxygenation of blood and is structured and arranged to return the blood to the mammalian body.

2. The artificial lung device according to claim 1, wherein the electrically actuated three-way valve receives exhaust air from the miniature enclosed fan via a duct.

3. The artificial lung device according to claim 1, wherein the cylindrical casing has an effluent duct connected to the exhaust fan.

4. The artificial lung device according to claim 1, wherein the electrically actuated three-way valve has an effluent duct structured and arranged for connection to the trachea of the mammalian body.

5. The artificial lung device according to claim 1, wherein the electrically actuated three-way valve has an effluent duct structured and arranged for connection to the cylindrical casing.

6. The artificial lung device according to claim 1, wherein the cylindrical casing has a influent duct connecting loops of oxygenator fibers to pulmonary arteries of the mammalian body.

7. The artificial lung device according to claim 1, wherein the cylindrical casing has a first effluent duct connecting loops of oxygenator fibers structured and arranged for connection to pulmonary veins of the mammalian body.

8. The artificial lung device according to claim 7, wherein the cylindrical casing bottom has a second effluent duct for collecting any blood leakage, and is connected to the first effluent duct that is structured and arranged for connection to the pulmonary veins of the mammalian body.

9. The artificial lung device according to claim 8, wherein the second effluent duct has a check valve.

10. The artificial lung device according to claim 8, wherein two artificial lung devices are used in parallel.
