Home oxygen concentrators, application

Anyone can get sick with diseases such as chronic obstructive pulmonary disease, chronic bronchitis, asthma, or another disease. The cause or result of which is respiratory failure. But no matter how scary the symptoms of the disease may sound, it is quite possible to treat them at home, and not go to the hospital.

For people suffering from these ailments, oxygen therapy has been carried out for over ten years using oxygen equipment called home oxygen concentrators. Medical equipment has proven its safety and ease of use. For obvious reasons, the oxygen concentrator should be maintained in good condition, which even the patient himself can perform. 

The safety of a home oxygen concentrator is always paramount. Year after year, scientists are improving the quality of the apparatus. Currently, it is already able to even work from an internal battery if there is no power supply at the time of treatment. The concentrator is ready to be fed not only from a spare battery, but also from an emergency gasoline generator.

What is the work of medical equipment? It allows the physical separation of gases at room temperature. There are a number of filters inside the device. Once inside the apparatus, ordinary room air passes through a kind of “molecular sieve” of aluminum silicate and is thereby purified. When air enters the home oxygen concentrator, oxygen is separated from nitrogen. If the first passes through zeolite, then nitrogen binds to it.

At that moment, when the column is filled with nitrogen, air flow begins to be supplied to the second column. Meanwhile, the contents of the first column are released into the atmosphere, thereby removing most of the nitrogen from it. Using oxygen from the second column, the remaining nitrogen is washed out from the first column. The oxygen separation process will switch back to the first column as soon as the second is completely saturated with nitrogen.

The service life of zeolite crystals is about 10 years, this is a minimum of 20,000 hours. A sick person in need of oxygen receives it through a stream controller and a small tank. The main part of home concentrators is limited by oxygen supply to 4 l / min.
