Oxygen Therapy Needs of Different Populations

Patients in the acute attack or recovery period of asthma:During an asthma attack, the oxygen concentration needs to be increased quickly to relieve wheezing. Our oxygen concentrator has 5 high-flow levels, and the oxygen concentration is continuously maintained at 93% ± 3%. After inhalation, the alveolar oxygen partial pressure increases, which promotes the binding of oxygen to hemoglobin, and can provide emergency support during acute attacks. During the asthma recovery period, hypoxia needs to be prevented when going out. Our oxygen concentrator can be powered by batteries, weighs only 1.2 kg, and is very small. It is also equipped with a backpack, so oxygen can be easily supplied when going out.

Chronic obstructive pulmonary disease (COPD) patients:Shortness of breath and wheezing are common during daily activities (such as climbing stairs and doing housework), and long-term home oxygen therapy is required to improve blood oxygen saturation. Our oxygen concentrator weighs only 1.2 kg, which is easy to move from the bedroom to the living room, avoiding the limitation of the range of activities due to the bulky equipment; the 1-5 adjustable flow can match different states – use 1-2 when resting, and increase to 3-4 after activity, flexibly adapting to changes in respiratory load; 93% ± 3% constant oxygen concentration ensures the effect of oxygen therapy, avoiding the concentration fluctuation caused by flow adjustment of traditional oxygen concentrators.

Patients with interstitial lung disease and pulmonary fibrosis:The patient’s lungs will have a significantly reduced gas exchange function due to fibrosis, and may face hypoxia even at rest.A stable oxygen concentration of 93% ± 3% can quickly increase blood oxygen saturation and more reliably improve tissue hypoxia. Continuous low-flow oxygen inhalation can reduce hypoxic stress in lung tissue, relieve bronchial smooth muscle spasms, and indirectly slow down the rate of deterioration of lung function. The battery mode supports power outage emergencies (such as power outages at home) to avoid acute exacerbations caused by hypoxia.

Plateau Tourists:Altitude sickness (headache, nausea, and difficulty breathing) is more likely to occur at altitudes above 3,000 meters, and oxygen inhalation is needed immediately to relieve the symptoms. Our oxygen concentrator weighs only 1.2 kg and is equipped with a backpack, so it can be used at any time when hiking or driving. The battery mode supports use in scenic spots without power supply, avoiding dependence on fixed power supply. The oxygen concentration of 93% ± 3% is very efficient, especially suitable for continuous oxygen use in high altitude areas.

Elderly people who need to go out:Daily activities (such as climbing stairs, visiting parks, etc.) increase oxygen consumption and easily lead to “shortness of breath after activities”. If oxygen is not replenished in time, it may cause dizziness, palpitations, and even fainting. Our product weighs only 1.2 kg, and the elderly can easily put it in a backpack and carry it. The battery life is 3 hours, and the oxygen concentration is continuously maintained at 93% ± 3%, which supports continuous oxygen inhalation during walking and avoids stopping to rest due to fatigue. Whether you go to the hospital for a follow-up visit, attend the senior university, or go to the vegetable market, you can carry it with you and perform oxygen therapy anytime, anywhere.

People troubled by air pollution and smog:PM2.5 and harmful gases attach to the respiratory tract, affecting the oxygen exchange efficiency of the alveoli, indirectly causing hypoxia in the body. Our oxygen generator uses molecular sieve technology to generate 93% ± 3% high-concentration oxygen without relying on outside air. When the outdoor air quality is poor on haze days, users can directly inhale pure oxygen through the nasal oxygen cannula to reduce the amount of polluted air inhaled. When used with a battery, users can carry it with them when traveling on haze days (such as taking a walk or seeking medical treatment) to avoid coughing and wheezing caused by inhaling polluted air.

People who do mental work or stay up late:When working overtime or preparing for exams, the brain consumes a lot of oxygen, which can easily lead to dizziness and lack of concentration. Our oxygen concentrator weighs only 1.2 kg, is compact and portable, and can be adjusted from 1 to 5 levels. It does not take up desktop space when plugged in. The battery mode is suitable for temporary oxygen supplementation in scenes without sockets such as conference rooms and libraries. When you feel “drowsy” at 3 pm or rush to do a project late at night, turn on the 3-4 level flow rate, 93% ± 3% constant concentration, and it will relieve dizziness and restore clear thinking in 10 minutes. Before an exam/speech, temporary oxygen supplementation can reduce hyperventilation caused by tension (hypoxia inducement) and avoid forgetting words and calculation errors due to “brain hypoxia”.

Working Principle

Air first goes through the filter screen and filter device for filtration and then enters into the compressor. Then, air comes into the molecular sieve tower to separate oxygen and nitrogen. Nitrogen is adsorbed by the tower, while oxygen is directed to the oxygen tank through the catheter after going out of the tower and gathered in the tank, and finally delivered to users through the oxygen transport tube.
