Fighting COVID-19: Great, IIT-G comes up with excellent affordable products

IIT-G comes up with excellent affordable products – Fighting COVID-19 appears to have gained an upper hand thanks to affordable products brought out by IIT Guwahati.

The team at IIT-G comprising faculty, staff, students and alumni are working tirelessly to ensure Fighting COVID-19 does not lose vigour.

IIT-G comes up with excellent affordable products

They are developing innovative solutions to address sanitation and precaution concerns amid the pandemic with a set of affordable and innovative products which will strengthen Fighting COVID-19.

Some of the products developed to ensure Fighting COVID-19 continues are Low-cost heat-based Sanitizer Trunk, Injection Mould for mass manufacturing of Face Shield, Disinfectant Tunnel, Universal Foot Operated Hand Sanitization System and High-grade quality of Face Shields.

Speaking about the innovations to help sustain Fighting COVID-19 Dr. T.G. Sitharam, Director, IIT Guwahati said the Institute is continuously pushing the limits and thriving hard to serve the nation by developing innovative and affordable products to strengthen Fighting COVID-19.

This is in line with Prime Minister  Narendra Modi’s call for making the country self-reliant, ‘Atmanirbhar Bharat,’ he said.

IIT-G comes up with excellent affordable products

IIT Guwahati community is taking up the challenge to convert this time of crisis into an opportunity to serve society and will continuously work to contribute to the masses in this time of pandemic.

The aim is to ensure that vital products that are necessary for hospitals, offices, schools and colleges, private establishments to keep the population safe and secure are readily available at a reasonable cost.

‘I congratulate all the innovators and incubatees of Technology Incubation Center (TIC) of IITG.’ Fighting COVID-19 needs to be strengthened and these prouducts brought out by IIT Guwahati will strengthen that.

Low Cost heat-based Sanitizer Trunk
This was developed by a student team comprising Mr. N.K. Das, Mr. Dilip Chetri and Mr. L. Gogoi of the Department of Mechanical Engineering under the supervision of Dr. Uday Shanker Dixit, Professor, Department of Mechanical Engineering, IIT Guwahati.

This product will help strengthen Fighting COVID-19 as it can disinfect clothes, papers, leather items, belt, currency notes, wallets.

According to the team and various studies, the virus cannot withstand high temperature. According to one study, a temperature of 70° C is sufficient to kill coronavirus. Flu viruses are killed at 75°C.

The team has developed designs of low-cost sanitizer trunk of different sizes. A small sized sanitizer trunk has been developed for sanitizing the masks, wallets, currency notes etc.

The cost for making this trunk is only about Rs. 50. A 90 cm×45 cm×36 cm trunk may cost around Rs. 300. These sanitizer trunks work on the principle of thermal heating along with some amount of ultraviolet rays.

The procedure is to place the objects to be sanitized for about 15 minutes in the sanitizer trunk. The temperature of the trunk is about 85°C.

Injection Mould for mass manufacturing of Face Shield
Fighting COVID-19 can be strengthened with help of this equipment also. IIT Guwahati faculty, Dr. Supradip Das, Assistant Professor, Department of Design, has developed an injection mould for mass manufacturing of face shield to cater to the needs of the hospitals.

The injection moulded face shield is lightweight, approximately 25 gm. It is recyclable or reusable and autoclavable.

The face shield is not porous. Many of the products available are made of sponge or foam sheet. Objects made up of these materials are highly porous, there are gaps between layers and those areas are perfect hiding spots for germs.

The faculty has planned to produce 10,000 pieces of the face shield. So far, he has supplied 3,000 pieces to doctors, organisations and hospitals.

Disinfectant Tunnel
Vixudha Bio Product Pvt. Ltd., a startup incubated at IIT Guwahati, in collaboration with Oasis Fabrications, has designed and developed Disinfectant Tunnel (DT).

This product will also ensure Fighting COVID-19 continues. Dr. Mihir Kumar Purkait, Head of Centre for the Environment, and Professor, Department of Chemical Engineering, IIT Guwahati, and Dr. Prabir Kumar Saha, Professor, Department of Chemical Engineering, IIT Guwahati, are leading the startup.

Disinfectant tunnel is a full-body disinfection chamber meant to decontaminate the personnel at a time.

High-pressure nozzles spray the disinfectant fluid in fine mist occupying the whole chamber, this fluid disrupts the protein structure of microorganisms on the surface, thus killing them eventually.

The spraying continues for a set time of seven seconds.

Universal Foot Operated Hand Sanitization System
Another product which can strengthen Fighting COVID-19 is universal foot operated hand sanitizing system.

It is used for hand cleaning and sanitization. The system is low-cost, easy to use, energy-efficient, zero electrical energy use and electronic freehand sanitization system that can be operated by foot.

This mechanism uses the actuator in the press system of a hand sanitization bottle to piping out the sanitizer liquid towards palms.

Healthcare workers and members of general public sanitizes hands on a regular basis. However, if a contaminated hand touches the body or actuator of the spray unit it is likely to contaminate the sanitization system.

Thus, there was an urgent need of a system which will avoid touching of sanitizer bottle by hand to prevent contamination.

This system will reduce the risk of transmission through contaminated hands to a great extent and subsequently strengthen Fighting COVID-19.

This foot operable hands-free sanitization system is universal as because any size of hand sanitizer bottle from 4 inch to 9 inch height (100 ml to 1000 ml capacity) can be fit into the system.

The low-cost system is constructed with readily available construction materials and no complex mechanism has been used.

This innovation which can help strengthen Fighting COVID-19 is developed by Dr. Arun Chandra Borsaikia, of the Department of Civil Engineering.

High-grade quality face shields
Face shields are an important part of the equipment used for Fighting COVID-19 and Mr. Himujjall Sarmah, an Industrial Designer and an alumnus of IIT Guwahati, has manufactured high-grade quality of Face Shields to fulfil the need for face shields locally for the hospitals in Assam and Northeast India.

His design company, Izake Design and Consultancy Private Limited, is currently incubated at IIT Guwahati Incubation Centre and supported by Northeast Venture Fund, by NEDFI, Guwahati.

The company has designed digitally fabricated, via a CNC router, face shield that can be cut and assembled in three minutes.

These face shields are better, faster and cheaper in production. So far, they have successfully manufactured and distributed around 12,000 Face Protection Shields to about 650 doctors, hospitals nursing staff and individuals throughout Assam.

They have also donated 2000 Face Shields to Government officials/NGOs/GMCH-Guwahati for COVID-19 response.
