Classification and Function of Home Oxygen Concentrators

May. 05, 2022

Classification and Function of Home Oxygen Concentrators

Oxygen concentrator is an important tool to help people inhale oxygen. The following will introduce the classification and function of oxygen concentrators.

Classification and Function of Home Oxygen Concentrators

Oxygen concentrator is also called air separation equipment (referred to as air separation equipment), it is divided into many types, and there are many different types according to different classification methods.


According to the purity of the product, it can be divided into a device for producing high-purity oxygen with an oxygen purity of over 99.2%; a device for producing low-purity oxygen (also called process oxygen) with an oxygen purity of about 95%; a device for producing rich oxygen with a purity of less than 35% A device for oxygen (also called air liquefied).


According to different types of products, home oxygen concentrators can be divided into single-high product devices that simply produce high-purity oxygen; double-high-product devices that simultaneously produce high-purity oxygen and high-purity nitrogen; argon extraction devices or full extraction devices with attached extraction of rare gases .


According to the form of the product, it can be divided into a device for producing gaseous products; a device for producing liquid products and a device for producing both gaseous and liquid products at the same time.


According to the number of products, it can be divided into small equipment below 800m3/h; medium equipment with 1000-6000m3/h; large equipment above 10000m3/h.


According to different separation methods, it can be divided into low temperature rectification method; molecular sieve adsorption method and membrane permeation method.


According to the working pressure, it can be divided into high-pressure devices with a pressure of 10.0-20.0MPa; medium-pressure devices with a working pressure of 1.0-5.0MPa; and full low-pressure devices with a pressure of 0.5-0.6MPa. The classification method is artificial, and there can be other classification methods.


In a poorly ventilated environment is only one of the reasons for the occurrence of hypoxia, which belongs to environmental hypoxia. Hypoxia refers to oxygen deficiency, which is the general term for the lack of oxygen or oxygen deficiency in the air. It is understood that if you are in a special environment lacking oxygen, or although there is no lack of oxygen in the environment, you cannot take in enough oxygen due to your own reasons, or if you cannot fully absorb and utilize the inhaled oxygen, people will experience hypoxia. Hypoxia is mainly divided into four types: environmental hypoxia, pathological hypoxia, physiological hypoxia, and exercise hypoxia.


The harm of hypoxia is extremely great, there will be various symptoms of brain hypoxia, heart hypoxia, lung hypoxia, liver hypoxia, retinal hypoxia, kidney hypoxia, and hypoxia in the blood, which will affect your physical condition. The use of home oxygen concentrators and medical oxygen concentrators is the best way to treat hypoxia symptoms. Moreover, with the rapid development of science and technology, home oxygen concentrators have been widely used by people, because oxygen concentrators are quite cheap and practical, and are widely welcomed and praised by people.


Reminder: It is the best time of the day to use an oxygen concentrator to inhale oxygen before going to bed. First of all, from the perspective of prevention, cardiovascular disease often occurs in the middle of the night or in the early morning. Using an oxygen concentrator to inhale oxygen before going to bed can effectively prevent cardiovascular disease. outbreak. Secondly, the sedative effect of oxygen can improve sleep, especially insomnia caused by mental stress and excessive brain fatigue is very common.


How are home oxygen concentraotors classified? Home oxygen concentrators have entered the homes of ordinary people. When families buy oxygen concentrators, they are faced with a variety of oxygen concentrators, which is really messy. Many people do not know what types of home oxygen concentrators are available. How to choose the oxygen concentrator that suits you? Let's take a detailed look today!


How are home oxygen concentrators classified?


1. Electronic oxygen concentrator

It is now more common in pharmacies. The process of oxidizing and reducing precipitation of oxygen in the air is adopted, so it will not produce dangerous nitrogen like electrolysis of water to make oxygen. It is strictly forbidden to tilt and invert, otherwise the solution will be sprayed into the nasal cavity through the oxygen delivery tube, causing damage to the user. At the same time, other oxides are easily generated during the oxygen production process, and the produced oxygen contains chemical substances. The oxygen method consumes a lot of electricity. According to experts, the service life of the best electronic oxygen concentrator in the world is difficult to exceed 1000 hours. During the use process, it is necessary to ensure that the solution has a suitable concentration, otherwise the oxygen cannot be produced normally. The maintenance work of customers who choose electronic oxygen concentrators must be done well.


2. Molecular sieve oxygen concentrator

Molecular sieve oxygen concentrator is an advanced gas separation technique. The physical method (PSA) directly extracts oxygen from the air, and it is ready for use. Dangers such as high pressure and explosiveness are the most used by people today.


3. Chemical Oxygen Concentrator

The chemical oxygen concentrator adopts a reasonable pharmaceutical formula and is used in specific occasions, but it can meet the urgent needs of some consumers. However, due to the simple operation of the equipment, the high cost of use, the need to invest a certain cost for each oxygen inhalation, the inability to use it continuously and many other defects, it is not suitable for home oxygen therapy.


4. Oxygen-enriched membrane oxygen concentrator

This type of oxygen concentrator adopts the method of membrane oxygen generation, and the nitrogen molecules in the air are filtered by the membrane to achieve a concentration of 30% of the oxygen at the outlet. It has the characteristics of small size and low power consumption. However, the machine using this method of oxygen production has a fatal disadvantage, that is, once 30% of the oxygen enters the air, it is immediately diluted to 21%, which is no different from normal breathing. Therefore, it is difficult for this type of oxygen concentrator to require oxygen therapy. People who do not accept it will not have the effect of increasing oxygen in the body.
