How does a medical oxygen concentrator work?
Air, 80% nitrogen, and 20% oxygen concentrators are medical equipment that can help people with low oxygen levels in the blood. Power them by plugging devices into electrical outlets or using batteries. If you use a battery, you need to charge it by plugging it into a power outlet. Most concentrators also come with an adapter, so you can use the device while driving.
The medical oxygen concentrator receives the air, purifies it, and then distributes the newly formed air. Before entering the concentrator, the air is composed of 80% nitrogen and 20% oxygen. The oxygen concentrator uses this air and then discharges it in the form of 90% to 95% pure oxygen and 5% to 10% nitrogen. Separate the nitrogen to allow the patient to obtain the maximum dose of oxygen, because it is difficult to obtain this percentage of oxygen without the help of medical equipment.
How does the oxygen concentrator work?
Five-step concentrator process:
1. Inhale air from the room.
2. Compressed oxygen.
3. Remove nitrogen from the air.
4. Adjust the air delivery method.
5. Deliver clean air.
The working principle of oxygen concentrator-convert air into oxygen
The portable oxygen generator is composed of many parts. The compressor and the sieve bed filter are the main components. The compressor compresses the air filtered into the concentrator and then delivers the air in a continuous flow.
The compressed air is moved to the sieve bed filter. The sieve bed filter plays an important role because it is a device that removes nitrogen from the air. There is a material called zeolite in the sieve bed, which is a six-sided microscopic cube with holes on each side. This is the reason for removing nitrogen from the air.
Two screen beds are located in the beneficiation plant. After the air is first compressed in the concentrator, it is forced to enter the first sieve bed. Oxygen is sent to the product tank. Then the first sieve bed is filled with nitrogen. Next, the airflow is switched, and the compressed air is moved to the second sieve bed. The compressor of the first sieve bed is sent to the outdoors, and the air in the product tank returns to the first sieve bed.
The pressure drop from the first sieve bed and the weakening of oxygen caused the zeolite to release nitrogen. The oxygen and nitrogen recombine and are released into the room as regular air. The air is then compressed and sent to the second screen, where the oxygen is transported through the second screen to the product tank. After a few seconds, the whole cycle starts again from the first sieve.
Other important parts are the cooling system, which prevents the portable oxygen concentrator from overheating, and the nasal cannula that delivers purified oxygen after the oxygen passes through all the sieve bed filters. The casing helps to increase the oxygen absorption rate.
