Abstract

A long term oxygen therapy system having an oxygen supply directly linked with a patient'"'"'s lung or lungs may be utilized to more efficiently treat hypoxia caused by chronic obstructive pulmonary disease such as emphysema and chronic bronchitis. The system includes an oxygen source, one or more valves and fluid carrying conduits. The fluid carrying conduits link the oxygen source to diseased sites within the patient'"'"'s lungs. A collateral ventilation bypass trap system directly linked with a patient'"'"'s lung or lungs may be utilized to increase the expiratory flow from the diseased lung or lungs, thereby treating another aspect of chronic obstructive pulmonary disease. The system includes a trap, a filter/one-way valve and an air carrying conduit.

Claims

1. A collateral ventilation bypass trap system comprising:

a containment vessel for collecting discharge from one or more lungs of a patient;

at least one conduit having a first end connected to the containment vessel and a second end being configured to pass through the thoracic wall and lung of a patient at a predetermined site, thereby establishing fluid communication between the containment vessel and the inner volume of the lung; and

a sealing device being configured to provide a fluid tight seal between the at least one conduit and the thoracic wall and between the at least one conduit and the lung.

2. A collateral ventilation bypass trap system comprising:

a containment vessel for collecting discharge from one or more lungs of a patient;

a filter/one-way valve connected to the containment vessel;

at least one conduit having a first end connected to the containment vessel through the filter one-way valve and a second end being configured to pass through the thoracic wall and lung of a patient at a predetermined site, thereby establishing fluid communication between the containment vessel and the inner volume of the lung; and

a sealing device being configured to provide a fluid tight seal between the at least one conduit and the thoracic wall and between the at least one conduit and the lung.
