Different oxygen absorbers have different ways of producing oxygen, and the oxygen concentrators on the market are chemical oxygen concentrators, molecular sieve oxygen concentrators, oxygen-enriched membrane oxygen concentrators and electronic oxygen concentrators, the specific ways of producing oxygen are as follows:
The first one: chemical oxygen concentrators
Chemicals Oxygen generator, alone from the name above, we can also know that this is not necessarily applicable to civilian use. This oxygen generator equipment, compared to other equipment, more simple, the operation is also more complex, because the internal will use the formula of the agent.
So the cost required for each job is relatively high, the family is generally not applicable, and the proportion of the agent is also a troublesome thing, the use of personnel, it is unlikely to have the time and energy to do it themselves, so this form of oxygen generator, the market is very few.
The second type: molecular sieve oxygen generator
Molecular sieve oxygen generator oxygen generator, the current market appears more, this oxygen generator is used in the physical method of oxygen production, is the air as raw material, will be compressed into the air molecular sieve filtration tower, through the physical separation of the method of separation of oxygen and nitrogen in the air.
Thus the nitrogen is discharged and oxygen is derived. Compared with other oxygen generators, the molecular sieve oxygen generator is safer, and the pressure of the oxygen made is generally between 0.2-0.3Mpa, which will not explode because of the high pressure.
Third: Oxygen-rich membrane oxygen generator
Oxygen-rich membrane oxygen generator oxygen principle and molecular sieve has a little the same, to air as raw materials, and then inhaled into the machine, and then through the oxygen-rich membrane filtration, filtration of nitrogen molecules inside the air, but not all the filtration, but only to reduce the proportion of nitrogen contained in the air, so that the concentration of oxygen. Increase the concentration of oxygen.
The oxygen concentration produced by this principle can reach 30%, which is lower than the concentration required for medical emergencies, so it is more suitable for the family, and this oxygen concentrator is smaller in size and consumes less power, so it is very suitable for long-term oxygen therapy, but it is not suitable for people with serious respiratory diseases.
Fourth: electronic oxygen generator
Electronic oxygen generator that is home oxygen generator, the current drugstore, medical equipment stores are more common, the working principle is to absorb the air into the oxygen generator inside, and then with the internal solution to carry out the corresponding chemical reaction, and then come up with a pure oxygen and through the oxygen hole out, this type of The advantage of this type of oxygen concentrator is that the noise is relatively small.
But there are also problems, such as in the handling, must be carried vertically, careful and cautious, do not tilt or inverted, because then, there is a high probability that the solution inside will be poured out.
And then when the oxygen is produced, the solution enters the nasal cavity with the oxygen outlet hole. So, when we use it, we must pay attention to the concentration of the solution inside, and then, if necessary, keep your nose at a certain distance from the deoxygenation nasal aspirator.
Choosing an oxygen machine:
1, flow rate
In fact, one of the most important factors to consider when buying an oxygen machine is to check the oxygen flow rate capacity. The flow rate indicates the rate at which oxygen can be transferred from the machine to the patient.
Some oxygen machines may have lower flow rates (in the range of 250-750 milliliters per minute), while others may have higher flow rates (in the range of 2-10 liters per minute, for example). Not all oxygen concentrators offer the same range of flow rates, so we need to be sure of the oxygen flow rate of the concentrator before we buy it.
2. Energy Consumption
Oxygen concentrators usually draw power from any ordinary wall outlet like any other household appliance. However, the energy used by the device varies greatly. While it is recommended to purchase the concentrator that uses the least amount of power, depending on your doctor's prescription, oxygen demand may lead to the purchase of a device that uses more power. Additionally, some models have the option of using consumer-grade batteries, which can be helpful in the event of a power outage.
3. Mobility
Generally home oxygen concentrators are large and a bit heavy, with a couple of wheels on the bottom, which are mainly there to make it easier for us to move around. Like home oxygen concentrators are very different from portable oxygen concentrators, there are some units that are more powerful and used to work harder and provide a higher flow rate, usually bigger is heavier.
Home oxygen concentrators provide higher flow rates and are great for patients on home oxygen therapy. There are also portable oxygen concentrators, which usually weigh between 2-4 kilograms. These portable oxygen concentrators sacrifice higher flow rates to make them easier to transport and use when on the go.
4. Oxygen Concentration
After compression and filtration in the oxygen concentrator, the oxygen delivered to the patient is typically above 90% pure oxygen. Known as oxygen concentration. Most oxygen concentrators have an oxygen concentration between 87% and 99%.
5. Noise decibel level
Home oxygen concentrators work by drawing in air from the environment and filtering out the oxygen, which creates some noise. If you are very sensitive to noise, you may want to consider a concentrator that operates quietly. 40dB is equivalent to the sound of a bird chirping, and 60dB is equivalent to the sound of a close conversation or a running air conditioner.
6. Warranty
Like any appliance, oxygen concentrators come with a warranty. However, each manufacturer has a different warranty policy. Oxygen concentrator equipment is more durable and it's best to check the warranty policy beforehand to make sure it's covered.
Oxygen concentrators can also be used as life-saving devices that can easily and efficiently deliver oxygen to patients who are unable to obtain enough oxygen on their own. Oxygen concentrators can utilize any ambient air that is filtered, processed, and compressed, and then deliver pure oxygenated air into our bodies.
