Abstract
An implantable artificial lung includes a fluid 5 filled compressible container 4 for compressible artificial alveoli 3. Each artificial alveolus is constructed with a perforated inner sphere and a closed outer sphere. An arterial tube is connected to the outer sphere of the alveolus whilst the inner sphere is connected to a bronchial air tube. Blood is oxygenated and carbon dioxide removed across the perforated sphere due to pressure variances. The artificial lung is connected to the body by a pulmonary artery connector 6, a bronchus connector 7 and a pulmonary vein connector 8.

Artificial Lung Naturally Driven Descriptior
The A=tifici1 rung Nat-'lrally Driven can replace one or both lungs.
Fig 1 is,= three dimensional view of the A=rificia: Lung Naturally Driven. Fig 1,1 is a version of the Artificial Lung Naturally Driven. which MOTIF not Create as much Oxygen to blood or CO? from blood throughput as the surface area of the holed tube Fig 1 does not have as much surface area as that cuff the Ghosts attifiC tat alveolus Fig 1.3. Fig 1.4 is flexible plastic container for the lung alveoli elements. Fig 1.5 is a fluid which may be liquid or oil based which will ensure that the pressure which each of the artificial alveoli in the plastic container experience is the same due to the intercostal muscles and the movement of the diaphragm of the body. Fig 1.6 is a connector for the pulmonary artery for the Artificial Lung Naturally Dri-ven shown, there is a pulmonary artery for each lung. Fig 1.9 is a pulmonary artery. Fig l,7 is a connector to a bronchus of the trachea of which there are two, one on the left side and one on the right side of the body of the patient. Fig 1. 8 is a connector to a pulmonary vein, there is a pulmonary vein for each lung. Fig 1.11 is a pulmonary vein.
Fig 2 is an three dimensional side view of an artificial alveolus. Fig 2. 1 is a flexible tube that functions as a derivative bronchus from the primary bronchus which goes inside the perforated sphere.
Fig 2.2 is a flexible tube that functions as a pulmonary artery derivative tube which connects with the exterior closed sphere. Fig 2.3 is a flexible tube that functions as a pulmonary vein derivative tube which connects with the exterior closed sphere. Fig 2.4 is the internal perforated sphere. Fig 2.5 is the external closed sphere. Fig 2.6 is a separator partition between the blood flow from the pulmonary artery to the pulmonary vein which routes the blood flow between the two ensuring Oxygen take up by the blood and CO) t Carbon C,io,xide) emission from the blood.
Fig 3 is a view from the rear of the artificial alveolus. Fig 3.1 is Fig 2.1. Fig 3.2 Is Fig at Fig 3.3 is Fig 2.3. Fig 3.4 is Fig 2.4. Fig 3.5 is Fig 2.. Fig 3.6 is Fig 7..
Fig 4 is view from abc.ve of the arti fic.i1 alveolus. Fig 4.1 is Fig 2.1. Fig 4.2 is Fig 2.2.
Fig 4.3 is Fig 2.3. Fig 4.4 is Fall 2.4. Fig 4.5 is Fig 2.5. Fig 4.6 _S F7g 2.6.
Fig is a view from the Side (6 the connections of the pulmonary artery, brorlcnls =.i the puLmon-rv-vein to the Artificial Lung Naturally Driven end the deri-vetiv-e tubing of these=. Fig 5.: is a pulmonary artery derivative tube. Fig.2 is a.h reed. Fig 5.] Its a nut. Fig 5. squeezes up against the pulmonary artery to secure the pulmonary artery to tile Artificial Lung Naturally Driven. Fig 5.5 is a tube. Fig S.6 is a wider diameter section of the tube. Fig 5.7 is pulmonary artery pushed up the tube. Fig.E is the pulmonary artery. Fig 5.9 is a bronchus derivative tube. Fig 5.10 is a thread. Fig 5.11 is a nut.
Fig 5.12 squeezes up against Fig 5.13 which wren squeezes onto the bronchus of the trachea by pressure fit thus connecting the bronchus of the trachea to the Artificial Lung Naturally Driven. Fig 5.14 is a slot to enable the inner connecting tube to grip onto the bronchus.
Fig 5.15 is the tube that grips onto the bronchus.
Fig 5.16 is the bronchus of the trachea. Fig 5.17 is a pulmonary vein derivative tube. Fig 5.18 is a thread.
Fig 5.19 is a nut. Fig 5.20 squeezes up against the pulmonary vein to secure the pulmonary vein to the Artificial Lung Naturally Driven. Fig 5. 'i is a tube.
Fig 5.22 is a wider diameter section of the tube.
Fig 5.23 is a pulmonary vein pushed up the tube.
Fig 5.24 is a pulmonary vein derivative.
When the chest has expanded the artificial alveoli are spherically shaped and air is sucked into theme Oxygen in the air is thus sucked into the haemoglobin of the blood to oxygenate the blood from the pulmonary artery derivative tube so that oxygenated blood is output from the Artificial Lung Naturally Driven via the pulmonary vein derivative tube. When the chest contracts artificial alveoli are squeezed and due to pressure Carbon Dioxide is forced out from the blood and out of the Artificial Lung Naturally Driven. The perforations in the inner perforated sphere of the artificial alveolus are so small a diameter that blood cannot escape through them but Oxygen and Carbon Dioxide can be passed through these holes and thus Oxygen can get to the blood and Carbon Dioxide can be removed from the blood. The chemical bond is weak enough to allow Oxygen to be absorbed by the blood and Carbon Dioxide to be removed from the blood due to pressure variances engendered in the artificial alveolus.
Claims (2)
1. The A=tificial Lung Naturally Driven can be used as a replacemelt to a lung that is not functioning satisfactorily, it consists of a compressible container which contains compressible ar' if icial alveoli r the space between the container arid the artificial alveoli is liquid filled, each artificial a lveolus is composed of an inner perforated sphere and an outer closed sphere which are both compressible, there 7 s a tube going into the outer closed sphere of the artificial alveolus which is a pulmonary artery derivative tube and via a route the blood can once it has been oxygenated and Carbon Dioxide removed go through a tube which is a pulmonary vein derivative tube, there is a tube going into the inner perforated sphere which is a bronchus derivative tube, there are connectors to connect the Artificial Lung Naturally Driven to the pulmonary artery, to the bronchus of the trachea and to the pulmonary vein of the lung to be replaced.
2. The Artificial Lung Naturally Driven is substantially as described herein with reference to the accompanying
description and drawings.
