Many people who need oxygen concentrators always ask some questions:

Where does the oxygen of the oxygen concentrator come from?
What materials does the oxygen concentrator use to make oxygen?
Will the oxygen concentrator use up all the air in the house?
A 10-liter oxygen concentrator is so expensive, can't I use a 5-liter one?
……

In fact, it is all because of the lack of understanding of the principle and type of oxygen concentrators. DEDAKJ will popularize the principle and types of oxygen concentrators for you. Help you make the right choice easily!

1. Working principle of home oxygen concentrators

At present, mainstream home oxygen concentrators use adsorption oxygen production. The core technology is molecular sieve pressure swing adsorption technology to separate oxygen and nitrogen in the air. This process can be roughly divided into the following steps:

Air inhalation: The machine first inhales air from the environment. The oxygen concentration in the air is 21%

Filtration and compression: The inhaled air passes through the filter to remove impurities, and then is compressed to increase the oxygen concentration.

Molecular sieve separation: The compressed air passes through the molecular sieve, adsorbs nitrogen and allows oxygen to pass through. Achieve oxygen separation and collection.

Output concentrated oxygen: The gas that has passed through the molecular sieve is rich in oxygen and is output to the user through a pipe or mask.

The oxygen concentrator does not actually produce oxygen, but collects oxygen from the air. Air is flowing, and as long as it is not a completely closed space, the oxygen will not run out.

2. The difference between stationary home oxygen concentrators and portable oxygen concentrator machines

According to the usage scenario and volume weight, home oxygen concentrators can be roughly divided into two categories: portable oxygen concentrators and stationary home oxygen concentrators.

01,Stationary home home oxygen concentrator

Appearance:stationary home oxygen concentrators are usually larger and must be connected to a power supply. They are equipped with rollers for easy indoor movement and provide continuous oxygen supply.

Large flow output: Their oxygen flow range is wide, reaching 5L or even 10L, which can meet the needs of patients with severe oxygen demand. 5L or more can also be connected to a ventilator.

Continuous or pulse oxygen supply:stationary home oxygen concentrators are large in size and have sufficient internal space, which can provide users with continuous and uninterrupted oxygen supply. Some models also have pulse oxygen supply function to meet different needs.

Can be connected to a ventilator: Due to its large flow rate and continuous oxygen supply, the stationary home oxygen concentrator can be connected to a ventilator through an oxygen tee, which is suitable for people with breathing difficulties such as severe COPD.

02, Portable oxygen concentrators

Lightweight design: The portable oxygen concentrator is small in size, light in weight, easy to carry, and suitable for use outdoors, traveling or daily outings.

Flexible power supply: Equipped with a battery, it can be charged with AC or DC power, and even used in a car.

Output mode: Portable oxygen concentrators mostly use pulse oxygen supply mode, automatically adjusting oxygen output according to breathing needs, saving more oxygen.

Flow range: Due to the limitations of volume and battery, the oxygen flow of portable oxygen concentrators is usually low, suitable for users with mild to moderate oxygen needs.

3, Choose according to needs

When choosing a home oxygen concentrator, the following key factors should be considered:

Oxygen demand and usage scenarios:

If it is a group that needs a large amount of oxygen supply, such as severe COPD, it is recommended to choose a stationary home machine with a ventilator.

If the symptoms are mild and there are more groups with more needs to go out, a portable machine is a better choice. Portable machines are also more suitable for plateau travel or white-collar office travel.

Budget:

Portable oxygen concentrators are generally more expensive, but they improve the quality of life more significantly.

Some stationary home oxygen concentrators are very low in price, but the actual oxygen output effect and quietness must be considered. Generally, quieter oxygen concentrators are more expensive.

On the whole, if you are a patient with lung problems such as COPD, it is recommended to choose a stationary home oxygen concentrator such as DEDAKJ JAY-10. An oxygen concentrator that can be turned on and run continuously for 365 days. The customer's actual machine has been used for more than 32,000 hours and still outputs 93±3% oxygen at a stable concentration. More stable and durable.

If you are a plateau tourist, pregnant mother, white-collar worker, or have a mild disease and need to go out, it is recommended to choose portable oxygen concentrators such as DEDAKJ KPA, KPC and KPS. Lightweight and portable, free to go out; ultra-long standby, you can replace the battery with you. The accessories are versatile, and fast charging can also be used for mobile phones and computers.
