Prof. Nachiketa Tiwari, Department of Mechanical Engineering, IIT Kanpur and Prof Devendra Gupta, In-charge, Covid-19 ICU (SGPGI) have developed a working prototype of a Positive Pressure Respirator System. The PPRS system addresses the problem of the acute global scarcity of N95 respirators, which are a critical component of PPE Kits.

 

It is a safer alternative to the N95 respirator as it provides uncontaminated air and isolates the health professionals from the exposure to the virus.

 

It can be built fairly quickly, using local resources & in large numbers.

 

 

 

 
 

IIT Kanpur has successfully implemented a low cost rapid disinfectant process at our Health Centre for the outsiders coming to campus to sanitize anyone (external disinfection) under the guidance of Profs. Manindra Agrawal and Deepu Philip. The process aims to achieve a high rate of personnel disinfection within 2 minutes. Local hospitals and district administration have approached us to implement this at strategic locations in Kanpur.

 

Majority of the approaches of individual disinfection process focuses on exposing human touch surfaces like fingers, hand, etc. to soap based solutions and covering faces with masks to prevent droplet-based spread. However, residual germs residing on clothes, sleeves, masks, etc. are not eliminated by this process. This proposal focuses on innovatively combining two common disinfection approaches followed across the world to achieve a new and cost-effective disinfection process that is safe for human beings.

Option for manual affordable system (without robotics, Lithium Ion Battery system, LIDAR sensor and PLC) to reduce the cost.

 

 

 
 

Spread of COVID-19 has resulted in a huge demand for personal protective equipment (PPE) for workers in essential services exposed to high-risk environments. As standard PPE kits become scarce, there is a need for low-cost and mass producible alternatives that provide protection for the entire body.

A team of researchers led by Dr. Nitin Gupta & industry partners based on thin cylindrical rolls/pipes of polyethylene, which is non-porous & commonly used in the industry for packaging & making plastic-bags. Polythene material makes airtight and will provide required protection. It can be easily mass manufactured and transported at scale. The technology is made open source for anybody to make it. Easy to scale, cost effective and relevant particularly as imported kits are difficult to get.

 

 

 
 

Dr. Dibyendu Kumar Das, Department of Biological Sciences and Bioengineering, IIT Kanpur and his team have aimed to develop replication-competent vaccines against Novel coronavirus (SARS-CoV-2) based on attenuated recombinant vesicular stomatitis virus (rVSV) vectors expressing the novel corona virus spike (s) glycoprotein (rVSV-SARS-CoV- 2S). Vaccines, designed on live attenuated recombinant VSV template have been highly effective in animal models and are particularly appealing because they can be administered mucosally. Additionally, VSV rarely infect human and the chance of infection due to VSV is negligible. Recently, recombinant VSV based Ebola virus, Marburg virus and Lassa virus vaccine has been developed and tested effective in nonhuman primates model. The rVSV-ZEBOV-GP vaccine against Ebola had been 97.5% effective at stopping Ebola transmission, relative to no vaccination, approved by WHO in 2019 for vaccination.

Dr. Swaprava Nath, Department of Computer Science and Engineering, IIT Kanpur and his team have developed a app of Contact tracing and fake news verification App. The users of social media apps like WhatsApp or Twitter can easily check whether a news received is fake or not (in a much simpler manner than the usual apps). What makes our solution stand out from the other such detectors is that the checking methodology is extremely simple.

 

The users do not need to open a different app or google the news to find this out, it will happen by just forwarding the message to a saved contact. The ease of use is the biggest impact that this project wants to create for fake news detection. This can be used with non-smart phone also and thus deployable in areas of limited telecom connectivity.

 

 

 

 
 

Dr. Pawan Mehrotra, Founder, Aarna Biomedical Products have developed SURAKSHA KIT - Whole Body Protection Wearable.

 

A holistic full body disposable wearable kit (named as SURAKSHA) for self-protection of personnel in vulnerable environments such as the security guards, municipal workers, sanitization workers, personnel involved in testing patient samples, health professionals and paramedics employing a user-centric approach, in-house development and production skills for the larger benefit of our nation. The wearable kit would comprise of a full-face shield, face mask, a coverall with fused head coverage, shoe covers and hand covers. We aspire to make this holistic wearable kit at an affordable price for the masses and aspire to reduce the price further with growing demand. The above is tenable and implementable after immediate funding support and approvals for logistics and manufacturing.

A team led by Profs. Nagma Parveen, M.L.N Rao Ashish K Patra from the Department of Chemistry have been granted funding from DST/SERB for developing a preventive and cost-effective surface coating. This coating will be applied in making medicated masks and medical wear (personal protective equipment, PPE) as a preventive measure for COVID-19, in particular, for doctors and nurses who are susceptible to contamination while treating infected patients.

 

The idea is based on a combination of anti-microbial polymer coating and functionalized virucidal drugs/agents to attain a synergistic anti-viral effect.

 

The team aims to develop a basic prototype within three months and further, collaborate with potential industrial and/or start-up partners for its potential large-scale applications.

 

 

 

 
 

A team of researchers led by Profs J.Ramkumar & Tarun Gupta and alumnus Sandip Patil are working on a protective face mask which is equivalent to N95 face mask for the front line medical staff and common man fighting against COVID-19.

 

The primary goal is to test various available filter media and develop a low-cost protective respirator which is equivalent or even better than N95. We have to quickly set up a filter testing rig equipped with an aerosol laser spectrometer and identify a non-woven polypropylene based 3-4 layer material as the likely candidate to make such mask. Its efficiency must be equal to N95 and it offers much lower resistance to the air passage.

 

Scalability:After identifying the appropriate material the mask will be made manual because the ultrasonic welding machine and automatic manufacturing machines are also a bottleneck at this lock down period. We will identity few profession stitches who have prior experience in textile and mask fabrication. Initially for few days we would be able to manufacturing 500 piece/day. Slowly we will ramp up the production to 2000/day.

 

 
 

Prof. Amitabha Bandopadhyaya of Bioscience and Bioengineering Department, IIT Kanpur is coordinating an effort led by a large team for rapid development and production of portable ventilators which will be life saving for COVID-19 patients, particularly the elderly.

 

 

 

 



 
 

Mr. Ravi Pandey from SIIC at IIT Kanpur has developed an Anti Viral Nasal filter, the need for this filter arise considering the recent outbreak of corona virus, where the main channel of transmission occurs by the transfer of droplets to a healthy person through air. There have been several similar outbreaks that utilize air as the main transmission channel. However, such transmission of diseases can be stopped using different filters for mouth and nose. Since 90% of the breathing occurs through nasal cavity only, hence nasal passage is the main source of contamination.

 

 
The existing masks comprise different straps to hold on to the face of the user and are uncomfortable to wear during different activities of the day. There was a need for a filter that filters the nano particles including any viruses with high filtration efficiency. The present invention minimizes the leakage of air, that occurs from sides while wearing a N95 mask, without maintaining positive pressure inside the filter.
