If you want to buy an oxygen concentrator, I recommend it.

The difference between industrial oxygen concentrator and medical oxygen concentrator 1. The difference in the definition of oxygen concentrator: Industrial oxygen: refers to the industrial use of oxygen.

Industrial oxygen generally only requires oxygen purity, and there are no special requirements for other sanitary conditions. At the same time, it also contains harmful gases such as carbon monoxide and methane, and is also high in moisture, bacteria and dust. Industrial oxygen is mainly used for welding, gas welding, gas cutting, etc.

Medical oxygen: refers to oxygen with an oxygen concentration of 93% and quality requirements. It is used as an adjunct to respiratory diseases, heart and cerebrovascular diseases caused by hypoxia, to alleviate the symptoms of hypoxia; It can also be used for health care oxygen inhalation or rapid relief of fatigue after intense mental and physical work.

2. The difference between oxygen concentration and purity: Industrial oxygen: oxygen concentration of more than 90% is qualified, with low purity and many impurities. Doctor....

Oxygen concentrators are relatively good Invecom, Xinsong, Turtle, Kaiya, I don't know what your economic conditions are, if there is no big problem, buy a 3-liter machine, it's OK, if your conditions are good, just buy an Invecom, Inwellcom is a 5-liter machine, the flow is large, the concentration is also high, if you can only accept between 2,000 and 4,000, you can buy a 3-liter machine, and you can see which model is suitable for you. I'll recommend you a ** "Oxygen Weikang" You search, there are those for sale, and I also know their company's Q 3 5-7 I-3 6

Inwellcom, Xinsong, Turtle, Kaiya, these are good, if the conditions are good, buy Inweekon, the conditions are generally to buy a few others, what kind of machine you are suitable for, depending on the situation of your family, it is recommended that you ask the seller's customer service, most of them are studying medicine, understand some, and have experience to help you find a suitable one for you. "Oxygen Weikang", you can search for it yourself.

Home oxygen concentrators can be purchased at local pharmacies or hospitals.

When confirming the purchase, you need to confirm the after-sales maintenance of the product with the merchant in person. Be sure to read the instruction manual carefully before using it. For the use of the process, in case of difficult problems, do not deal with it privately, be sure to contact the merchant as soon as possible to assist in solving it.

Personally, it is recommended to go to the physical store to buy more assured, now the brands are varied, due to the lack of strict supervision, many health-care oxygen generators focus on the side of the large flow and ignore the oxygen concentration. Only 5 liters of medical oxygen concentrators are purely imported. Domestic medical oxygen concentrators are divided into 3 liters and 5 liters (that is, on the basis of the maximum oxygen flow rate, it can guarantee the standard of 93% +-3).

How to choose a home oxygen inhaler?

1. Look at the oxygen production method of the oxygen generator. There are three oxygen production methods of oxygen production mechanism, which are the principle of molecular sieve, the principle of polymer oxygen-rich membrane and the principle of oxygen production by chemical reaction. Among them, only the molecular sieve oxygen concentrator is the only mature oxygen concentrator at present, and it is the only oxygen concentrator with international standards and national standards.

2. See the magnitude of oxygen concentration. The size of the oxygen concentration is one of the important factors in judging the quality of the oxygen concentrator, and the oxygen concentration of a first-class oxygen concentrator should be stable at 90%.

3. Look at the core components of the oxygen generator: molecular sieve and air compressor. Air compressor, need to use high-efficiency, oil-free compressor, if the use of oily compressor will pollute oxygen, and harmful to the body, and a good oil-free compressor, requires strong performance, good heat dissipation performance, and low operating noise, and to ensure a long service life.

There is a role。When buying an oxygen concentrator, you must buy a big brand.

I've given you a summary of the dos and don'ts of shopping.

1.To select a model with an oxygen generator output of 90% oxygen concentration, the oxygen concentration can be detected by means of an oxygen monitoring device provided by the instrument or machine.

2.The noise level of the oxygen generator is preferably less than 45 decibels. The oxygen concentrator is an electrical appliance that works for a long time, and the sound must not be too loud, otherwise it will affect the rest of yourself and others, especially at night, so the sound of the motor at work should be low.

3.A good Yecong early oxygen concentrator manufacturer should have ISO international and CE European quality system certified oxygen concentrators (oxygen concentrators), and pay attention to brands that have been on the market for more than two years, so as to have better quality assurance and related certifications.

4.Strong oxygen production capacity. A good compressor of 10-15 liters of air produces 1 liter of oxygen concentration, while a regular compressor of 27-30 liters produces 1 liter of oxygen concentration.

5.It has a cumulative timing function. The service life of the oxygen machine can be counted, and objective and accurate data can be provided for long-term maintenance and service in the future.

International standards require oxygen concentrators to be equipped with a totalizer, which is also a reflection of product quality. A good oxygen concentrator should have a service life of tens of thousands of hours.

1. The oxygen concentration of the oxygen generator.

The oxygen concentration of the oxygen concentrator refers to the size of the oxygen content, which is the purity of the oxygen output of the oxygen concentrator. The oxygen concentration of different oxygen concentrators is also different, and a high-quality home oxygen concentrator should have a stable oxygen concentration of more than 90% to ensure the effect of home oxygen therapy.

2. Look at the oxygen flow.

The oxygen concentrator has 1L, 2L, 3L, 5L, 8L, 10L, which means that the oxygen concentrator can provide the maximum oxygen flow per minute under the premise of oxygen concentration guarantee. Different populations use different oxygen flows:

1L and 2L are mainly used for health care and oxygen inhalation for people with mild hypoxia.

3L and 5L are the most common and the most, 3L is between health care and slight ** function, and the oxygen concentrator above 5L belongs to the ** type, which has medical assistance for patients with respiratory diseases and lung diseases.

8L and 10L are suitable for special patients who need high oxygen flow and long-term oxygen inhalation, such as severe COPD, pulmonary heart disease, stroke and other diseases, as well as postoperative oxygen sources and hospital oxygen sources.

3. The noise level of the oxygen generator.

It is recommended to choose an oxygen concentrator with low noise, and the noise level should not be greater than 50 decibels, otherwise, it may affect the rest of yourself and others, especially at night. People who are very sensitive to noise can move the oxygen concentrator relatively away from the oxygen absorber and connect it through a longer oxygen tube.

4. Continuous oxygen supply time.

If it is an oxygen concentrator that is only used for health care, it is often small in size, and the heat dissipation function is relatively poor, so it cannot work for a long time. Most of the medical oxygen concentrators used for ** function can work 24 hours a day.

For example, patients with chronic obstructive pulmonary disease (COPD) and chronic respiratory failure need no less than 15 hours of oxygen inhalation every day, so they need to choose to buy an oxygen concentrator that can provide oxygen for a long time, so as not to meet the best demand.

5. Look at the brand.

Oxygen concentrator belongs to household medical products, we must choose products with medical production qualifications and brand protection, professional and regular brands have more advanced oxygen production technology and perfect after-sales service system, and the use will be more assured.

I bought a Yongkang oxygen concentrator for my grandfather, which is the first choice for the elderly with low noise, high oxygen concentration, and oxygen can also be inhaled while sleeping. Moreover, the oxygen concentration of Yongkang oxygen generator is as high as 93%, with voice broadcast, it is very convenient for the elderly to use, and they will use it after teaching it, and the use feeling is also very good, and the body feels relaxed after inhaling oxygen. If you don't understand, you can also speed up to know and see.

The user groups that choose oxygen concentrators can be divided into 2 categories, one is health care type, and the other is disease type.

Good understanding of health care, office white-collar workers work a lot of overtime, especially program apes, all-night is a common thing, good companies should prepare a health care oxygen concentrator for everyone to inhale oxygen, to prevent the chance of sudden death.

The disease is usually suffering from cardiovascular and cerebrovascular diseases, coronary heart disease, cerebral thrombosis, hypertension, pneumonia, bronchitis, asthma or pulmonary heart disease, etc., if long-term oxygen inhalation will have a good effect.

Ask how to choose a good oxygen concentrator for disease machines.

2) Treatment and life-saving: more than 5L belongs to the ** type, when you inhale the maximum oxygen concentration produced by the 5L or 8L oxygen generator, reaching 93%, the oxygen concentration in the alveoli is 33-41%, for the patient, it can give sufficient oxygen to improve the comprehensive immunity of the human body, clean the respiratory system, and improve the function of internal organs.

Question: Does each machine show the number of oxygen?

What is my father's disease?

Ask about chronic bronchitis that few years of examination.

Choose 5L.

It's my pleasure to help you! Have a great day! If you think it is helpful to you, please give it a thumbs up! Thank you!

Ask what is the condition of 6 liters and 7 liters of **.

If you ask a question, you can use it, and if you have a large number of liters, you don't know what the benefits are.

It's my pleasure to help you!

Have a great day!

One of the most important factors to consider when an oxygen concentrator is to check the oxygen flow capacity. Flow rate indicates the rate at which oxygen can be transferred from the machine to the patient. Some oxygen concentrators may have a lower flow rate (in the range of 250-750 ml per minute), while others may have a higher flow rate (e.g. in the range of 2-10 litres per minute).

The purchase of household oxygen concentratorsEnergy Consumption Oxygen Concentrators usually draw power from any common wall outlet just like any other household appliance, however, the amount of energy used by this device varies greatly, and while it is advisable to buy a concentrator with the lowest power consumption, according to the regulations, your oxygen needs may cause you to purchase a higher power consumption device. In addition, some models also have the option to use consumer-grade batteries, which can be helpful in the event of a power outage.

MobilityGenerally, the household oxygen concentrator is relatively large in size, the weight is a bit heavy, there will be several rollers at the bottom, the role of the rollers is mainly to facilitate our movement, like the household oxygen concentrator and the portable oxygen concentrator are very different, there are some devices with high power, used to work hard and provide a higher flow rate, usually larger will be heavier.
