Problems solved by technology

[0004] However, all of the above-mentioned solutions require low-altitude flight altitudes, maintain a large amount of oxygen supply during flight, and require medical personnel to monitor and adjust oxygen supply, etc., which are not economically feasible. Furthermore, the existing air supply industry The demand dilution oxygen regulator used is used between barometric altitudes of 10,000 to 12,000 feet

Abstract

A system and method of automatic delivery of appropriate flow rate of oxygen to a person flying in a pressurized aircraft cabin is disclosed. In one embodiment, an adaptable demand dilution oxygen regulator for use inside a pressurized aircraft cabin, includes an oxygen initiation and demand regulation system adapted to be responsive to differential gas pressure in a first altitude range based on a pulmonary capacity of a person flying in the pressurized aircraft cabin and to control flow of pressurized oxygen to a breathing outlet during the first altitude range. The adaptable demand dilution oxygen regulator further includes a cabin air dilution and delivery system, coupled to the oxygen initiation and demand regulation system, adapted to be responsive to differential gas pressure in a second altitude range and to output progressively enriched mixture till 100% pressurized oxygen into a breathing apparatus during the second altitude range.

Description

technical field [0001] This invention relates generally to aeromedical equipment, and more particularly to demand-regulated dilute oxygen regulators for use in aircraft. Background technique [0002] The air pressure in the cabin of an existing aircraft is 3000 to 8000 feet expressed in barometric altitude, which is lower than the air pressure on the ground. Persons with impaired lung capacity should not be in a depressurized cabin with low oxygen content (low oxygen levels can be caused by the continuous circulation of air in the cabin by the air conditioning system / environmental conditioning system (ECS) in the aircraft. ), especially if infected or prone to infections including but not limited to chronic bronchitis, emphysema, bronchiectasis, dyspnea at rest, cor pulmonale, severe asthma, anemia (sickle cell hemoglobin and beta-thalassemia) and similar People with medical conditions, including those who have recently undergone cardiopulmonary surgery or compromised or in...
