Active respirator mask and nano-sanitiser can help in combatting COVID 1

New Delhi, July 22, 2020: The COVID-19 pandemic has made the use of face mask an inevitable part of daily life. However, as the population adjusts to this unavoidable protection gear, it is encountering many a discomfort which hinders its usage to prevent spread of the virus.

Some of them are rebreathing of Carbon dioxide (CO2), which may reduce human efficiency and lead to brain-hypoxia due to long hours of usage, moisture in the exhaled breath which makes spec-tacles foggy, safety issues like sweaty and hot environment inside the mask, clarity in speech of a person with a face mask.

An active respirator mask with attached exhala-tion valve and suspended particulate matter filter for comfortable and hygienic breathing while wearing masks has been developed by Professor Samir K. Pal and his group under the leadership of Professor Samit Kumar Ray, Director S.N. Bose National Centre For Basic Sciences (SNBNCBS), Kolkata. The institute is also host-ing one of the Technical Research Centres (TRC) funded by DST.

The Active Respirator mask is an innovative solution to the rebreathing of carbon dioxide, exhaled moisture and sweaty and hot environment inside the mask.

It also improves the clarity of speech of a per-son with a face mask and assures comfortable, hygienic breathing to protect the wearer from exposure to airborne contaminants.

Besides this, a Nano-sanitizer with a Dispensing Antimicrobial Layer has also been developed by the institute. The Long-Lasting Nano-sanitiser innovation is a solution to the problems caused by the use of the general sanitisers like dehydration of skin due to frequent use and nature of instanta-neous antimicrobial action of common sanitisers without protective role. This innovative sanitiser technology assures comfortable and hygienic hand sanitisation for a longer duration.

Both of these have been transferred by the National Research Development Corporation (NRDC) to a Kolkata based company, Paulmech Infrastructure Pvt Ltd. Shanti Ranjan Paul, Direc-tor of the company expressed satisfaction for get-ting opportunity to take part in the global fight against the pandemic COVID-19 in an indigenous way.

The target date of launching the first batch of both the products is fixed as August 15, 2020, the day of independence of our country.

The Agreement for technology transfer was signed by Dr H Purushotham, CMD, NRDC and Shanti Ranjan Paul, Director, Paulmech Infra-structure online in the digital presence of Profes-sor Ashutosh Sharma, Secretary, DST, Govern-ment of India and Prof. Samit Kumar Ray, Profes-sor Samir Kumar Pal, Registrar, Shohini Majumder, Dr Soumen Mondal, Priyankan S. Sharma, Somavo Gupta and senior officials.

Use of these innovative products will help users in overcoming the problems with masks and sanitisers available in the market.

Prof. Ashutosh Sharma, Secretary DST congrat-ulated all the stakeholders for benefitting society. Prof. Samit K Ray acknowledged the generous funding of DST in establishing the TRC in a basic Science Institute.
