The working principle of medical oxygen generator
If a person has respiratory problems such as asthma, COPD, lung disease or when undergoing surgery and other problems, the oxygen level in the body tends to become low. For such people, doctors often recommend the use of supplemental oxygen. The recent outbreak of the COVID event has also made us aware of the use and importance of medical oxygen.
Unprecedented times have taught us that it is rarely available to those who need it most. And, even if it is available somewhere, it is often expensive and generally cumbersome for the unluckiest (China has experienced dire shortages of ICU beds or ventilators amid the COVID-19 pandemic) . This is why all medical centers must develop medical oxygen systems and install on-site gas generators to provide an uninterrupted supply of oxygen whenever needed.
PSA (Pressure Swing Adsorption) technology is a practical option for on-site generation of oxygen for medical use. It has been used in the medical industry for over 30 years.
What is an oxygen concentrator?
Oxygen concentrator devices use molecular sieve beds to separate pure oxygen from the atmosphere to distribute air to people with low blood oxygen levels. On-site oxygen concentrators are cost-effective and more efficient than traditional oxygen tanks. Learn how medical oxygen concentrators work and the main components of these generators.
How does a medical oxygen concentrator work?
An oxygen concentrator is like an air conditioner in our home, it takes air, changes it and delivers it in a different form (cold air). Medical oxygen is generated from ambient air and delivered to people who need it due to low oxygen levels in the blood. In the past, medical institutions relied mostly on oxygen cylinders and Dewars, but since the technology developed, hospitals and nursing homes prefer on-site medical oxygen concentrators because of their cost-effective, effective and safe disposal.
Working process of medical oxygen generator
1. The generator gets air from the atmosphere.
2. Compressed oxygen.
3. Remove nitrogen from the air.
4. Adjust the way of gas delivery.
5. Deliver the purified air to the user.
The main components of the oxygen generator
Air Compressor: It helps to push the room air into the machine and pushes it into the molecular sieve bed.
Filters: Filters help filter out impurities from the air.
Molecular sieve: There are two molecular sieve beds in the factory. These sieves have the ability to trap nitrogen gas.
Switching Valves: These valves help to switch the compressed air flow between molecular sieve columns.
Flow Meter: Helps set the flow rate in liters per minute.
