Description

Walnut Medical is funded by CAWACH (Center for War Against Covid) fund by Department of Science and Technology (Government of India) in collaboration with IIT Delhi.

Walnut Medical has manufactured India’s first made in India oxygen concentration; two models are available 5 and 10 liter per minute flow rate:

  1. MS-OC-05 (5 liter capacity) (Single and Dual flow)
  2. MS-OC-10 (10 liter capacity) (Single and Dual flow)

 

Walnut Medical Oxygen Concentrator Working Principle

The composition of air (78% Nitrogen, 21% Oxygen and 1% other gases like Carbon Dioxide, Argon, etc.) clearly shows that air is mainly comprised of two gases: Nitrogen and Oxygen [together 99%]. If Nitrogen is removed from air, the primary gas remaining would be Oxygen with purity of about 90-95%.

Oxygen concentrators work on the principle of ‘Rapid Pressure Swing Adsorption’  which is where the Nitrogen is removed from the air using zeolite minerals which adsorb the Nitrogen, leaving the other gases to pass through and leaving oxygen as the primary gas.

Once the oxygen is collected the pressure then drops which allows Nitrogen to desorb and be expelled back into the air. An oxygen concentrator has an air compressor, two cylinders filled with zeolite pellets, a pressure equalizing reservoir and valves and tubes. During the first half-cycle the first cylinder receives air from the compressor, which lasts about 3 seconds. During that time the pressure in the first cylinder rises from atmospheric to a few times normal atmospheric pressure (about 20 psi) and the zeolite becomes saturated with nitrogen. As the first cylinder reaches near pure oxygen (there are small amounts of argon, CO2, water vapour, radon and other minor atmospheric components) a valve opens and the oxygen enriched gas flows to the pressure equalizing reservoir, which connects to the patient’s oxygen hose. At the end of the first half of the cycle, the air from the compressor is directed to the 2nd cylinder. Pressure in the first cylinder drops as the enriched oxygen moves into the reservoir, allowing the nitrogen to be desorbed back into gas. Part way through the second half of the cycle there is another valve position change to vent the gas in the first cylinder back into the ambient atmosphere, keeping the concentration of oxygen in the pressure equalizing reservoir from falling below about 90%. The pressure in the hose delivering oxygen from the equalizing reservoir is kept steady by a pressure reducing valve.
