Arjun B S and Ajay Krishnan A, two Bangalore-based engineering students, have been named national winners of the prestigious James Dyson Award 2022 for their unique innovation EpiSHOT. It is a reusable medical device used to treat patients who have a severe and potentially fatal systemic allergic reaction that occurs suddenly after coming into contact with an allergen.
Arjun is a PhD student, and Ajay works as a project assistant in Prof Hardik J Pandya’s Biomedical and Electronic Engineering Systems Laboratory (BEES LAB) at the Indian Institute of Science (IISc) Bangalore’s Department of Electronic Systems Engineering. Arjun B S and Ajay Krishnan A, the national winners, will receive approximately Rs 4.6 lakhs in prize money.
Intend to use the prize money to further modify EpiSHOT
The national winners intend to use the prize money to further modify EpiSHOT for commercialization, improving its manufacturability, reliability, and portability while lowering the device’s cost. The pair will also represent India in the international round, where the final winners will be chosen by Sir James Dyson. The international shortlist will be announced on October 1, and the international winners will be announced on November 16.
“The winning innovation is a single hand-operated autoinjector to deliver emergency medicine intramuscularly or subcutaneously to treat life-threatening situations like anaphylaxis with the provision for reloading and sterilization for reuse within two minutes of first use,” reads the official release.
“Allergies are prevalent among the Indian population, but no one believes that a simple allergic reaction could be life-threatening if not treated immediately. India, till-date, does not have an immediate solution to anaphylaxis, which shows preponderance for the age group 20 to 40 years,” says Arjun.
Challenge of developing such device was given by Dr Paramesh H
“Due to existing market monopolies, huge price tags of single-use autoinjectors, and safety concerns for self-use, there remains a greater need for a safe and cost-efficient solution. EpiSHOT aims to bridge this gap. The challenge of developing such a much-needed device was given to us by Dr Paramesh H, a pediatric pulmonologist who had spent decades trying to popularize epinephrine as an emergency response medication. We strongly believe that the James Dyson Award will be our stepping platform to get recognized, educate and mass materialize our lifesaving innovation,” he added.
“The design of EpiSHOT underwent multiple design iterations, with a few iterations made as prototypes. From adding a safety cap to the simple reusable single-hand-operated autoinjector to prevent accidental injection, to adding an automatic needle retraction mechanism to the design, from redesigning the syringe cartridge to prevent exposure to bodily fluids and more, multiple additions were made to the baseline design. More than a hundred tests were done on tissue phantoms to ensure complete safety of use,” said Ajay. The team is also developing similar technologies compatible with intradermal (DermiSHOT), subcutaneous, and intramuscular injections.
