CSIR-NCL and BEL manufacture Oxygen Enrichment Unit useful in Covid-19 treatment

PUNE: Oxygen Enrichment Unit (OEU), developed by scientists from Polymer Science and Engineering Division of CSIR-Nationwide Chemical Laboratory (CSIR-NCL), will assist scale back the requirement of ventilators and oxygen cylinders in homecare, villages and distant locations. The expertise has been licensed to NCL-start up GEnrich Membranes and the OEUs will likely be manufactured by Bharat Electronics Ltd. (BEL).

A launch from NCL, Pune mentioned, “Oxygen is required in greater focus for oxygen remedy in hospitals. It may be as excessive as 90% (ICU, operation theatre), whereas for treating sufferers with lung ailments (COPD, bronchial asthma), 27-35 % oxygen is required in respiration air. Regular air has 21% oxygen content material. Cryogenic expertise at -200 °C and stress swing adsorption to raise oxygen content material within the air are costly making oxygen enrichment gadgets unaffordable.”

A staff of scientists led by Ulhas Kharul, Head of the Polymer Science and Engineering Division of CSIR-Nationwide Chemical Laboratory (CSIR-NCL) have demonstrated the usage of hole fiber membranes to counterpoint oxygen.

“The Oxygen Enrichment Unit (OEU) developed by Kharul’s staff is environment friendly in offering 35-40% oxygen focus from air with an adjustable circulation price of 0.5-15 lit/min. Atmospheric air at 5-6 bar stress is handed by means of the membrane cartridge whereby the oxygen preferentially permeates by means of the membrane, because of intrinsic greater sorption capability of oxygen into the membrane matrix. The expertise was licensed to NCL start-up, GEnrich Membranes. About 50 items have been assembled and demonstrated in numerous boards, hospitals and first well being centres,” the discharge mentioned.

With the onset of Covid-19 pandemic, CSIR-NCL utilized for certification of a prototype OEU to TUV, Bangalore, which was discovered to be certified. “Overcoming a number of hurdles proper from materials provide to availability of manpower, CSIR-NCL and GEnrich Membranes shortly assembled three items in the course of the lockdown interval,” mentioned Kharul. Naidu Hospital at Pune is testing these items for treating mildly hypoxic Covid-19 sufferers for greater than a month.

CSIR-NCL has tied up with Bharat Electronics Ltd. (BEL), Pune for the manufacture of OEU together with GEnrich. Ok Rajendra, GM BEL mentioned, “Wanting on the rising medical disaster, BEL took this venture on warfare footing and manufactured 10 items in document time and that too with a skeletal workforce. BEL has plans to fabricate one other 100 items and provide in hospitals to fulfill the essential requirement”.

“Oxygen enrichment items have particular significance in view of the Covid-19 pandemic. Affected person restoration might be quicker with supplemental oxygen in early phases. It may scale back the variety of sufferers who will want ventilators. Put up-ventilator remedy sufferers might be served with this unit, thus lowering demand for oxygen cylinders. Its portability makes it handy for utilizing such items in house care, villages and distant locations,” the discharge from NCL mentioned.
