Ambient air is, of course, all around us. But for patients with respiratory viruses like Corona Virus, medical-grade oxygen is essential.
Ambient air contains 21 percent oxygen concentration. Medical grade oxygen can ramp that proportion up and is dispensed at a higher flow rate — helping patients efficiently oxygenate their bodies.
Corona Virus can cause a lot of respiratory distress and most patients who do die are as a result of extreme respiratory failure. With these sorts of symptoms, oxygen concentrators can prove to be very helpful in providing supplemental oxygen to relieve pain or difficulty breathing, and shortness of breath.
How do medical oxygen concentrators work?
All medical oxygen concentrators on the market today use a process called pressure swing adsorption (PSA), which is a dynamic process using columns, or beds, of molecular sieves to take air from the surroundings and separate the oxygen from other gaseous components like nitrogen, carbon dioxide and water vapor. This purified oxygen stream is sent to an internal accumulation tank, where it is fed to patients via cannulas worn on the face. Patients can adjust output to the desired flow setting prescribed by their health care providers.
Stationary oxygen concentrators are typically designed to deliver up to five liters per minute of approximately 90–95% pure oxygen to the user and can be used in home care settings.
Portable oxygen concentrators are devices that can be used by respiratory patients who are ambulatory and desire to lead a more active lifestyle without using compressed gas cylinders.
As one of main molecular sieve suppliers in China, Libra Lithium (LiX) molecular sieves are a critical component used in the manufacturing of many portable and stationary medical oxygen concentrators in the global market.
Libra Lithium (LiX) molecular sieve is a lithium-exchanged molecular sieve that provides twice the nitrogen capacity of earlier adsorbents and permits the design of the smallest, most energy efficient units. This technology has enabled a new class of portable oxygen concentrators.
In a concentrator, air passes through a packed bed of Lithium (LiX) molecular sieve where nitrogen is adsorbed, concentrating the 20% atmospheric oxygen to 90% or greater.
Libra Lithium (LiX) molecular sieve (0.4-0.8mm)is designed for portable oxygen generator 1-5L/Min,
Libra Lithium (LiX) molecular sieve (1.3-1.7)is designed for industrial oxygen plant, oxygen purity is up to 93%±3%.
