Prompted by the lack of sufficient numbers of fans throughout the coronavirus pandemic, Devesh Ranjan, professor and associate director of the prestigious Georgia Tech George w. Woodruff School of Mechanical Engineering, and his wife Kumuda Ranjan, practises as a family doctor in Atlanta, he developed the emergency ventilator from concept to prototype in just three weeks time.
“If you can make a manufacturing scale, which can be produced (cost element) in less than 100 USD. Even with a price of 500 USD, they (the manufacturer) would have enough money to make sure that you are making enough profit in the market,” said the Professor Ranjan told PTI.
Said a fan of this type, on average, in the united states, costs $ 10,000.
A fan is carried on the body, the breathing process when the disease has caused the lungs to fail. This gives the patient time to fight the infection and recover.
Ranjan, however, clarified that theirs is not a UCI fan, which is more sophisticated and costs more.
This Open AirVentGT has been developed for the management of acute respiratory distress syndrome, a common complication for COVID-19 patients that causes your lungs to harden, the need for assisted breathing by ventilators, he said.
The fan developed at the Georgia Institute of Technology uses electronic sensors and computer control to manage the key clinical parameters such as respiratory rate, tidal volume (the amount of air that moves in and out of the lungs during each cycle), the inspiration and expiration of the relationship, and the pressure in the lungs.
“The main objective of this project was to make a low-cost improvised fan that provides controls to the physician,” said Dr. Kumuda told PTI, pointing out that it’s not going to be a global shortage of fan given the massive spread of coronavirus, which until now has killed more than 345,000 people worldwide and has infected more than 5.4 million euros.
In the united States until Monday, more than 98,000 Americans had died and about 1.7 million had tested positive. Scientists are racing against time to develop a vaccine or come out with a therapeutic treatment.
Born and raised in Patna, Bihar, Ranjan earned his degree in engineering from the Regional Engineering College, Trichy, followed by the Master’s and Doctoral degrees from the University of Wisconsin-Madison and has been a professor in the Georgia Tech during the past six years.
Kumuda moved with his parents to the united states of Ranchi, when she was six years old. She did her medical training and residency in New Jersey.
Both Ranjan and Kumuda said that India had the potential to become a global low-cost manufacturing of fans and export all over the world at a rate that is affordable for all.
Professor Ranjan said that the low cost of the fan has been developed keeping in mind the needs of countries like India and in Africa, where the affordability of care is a very important factor in the delivery of health care to the people.
The idea was to develop a lost cost fan, which can be manufactured very easily using the already available supply chain in India, said.
Rajan said the team has been approached by the Georgia Tech alumni in Ghana and India to establish manufacturing lines in their countries.
“The impact of this could be significant if other parts of the world are affected by the COVID-19 pandemic. Having equipment that can be made quickly when necessary, and with the type of control system of the medical need could really help to address the global impact of this virus,” he said.
The prototype is being developed into a real product by Singapore-based Renew Group, headed by Ravi Sajwan, an Indian-American of Uttarakhand.
“We have built an extensive network of collaboration with a single objective of getting more fans in the poorest health systems in the world with the aim of helping doctors and patients dealing with COVID-19,” Sajwan said.
Address the shortage of low-cost, mechanical ventilators is a key focus of Renew the Group, who are collaborating with a group of companies and affiliates committed to fast-track the manufacture and distribution of medical of the degree of ventilation of the device, Open-AirVentGT to hospitals and remote facilities in under privileged countries such as India, Vietnam, Sri Lanka and Cambodia, the company said in a statement.
To maximize the effectiveness of the treatment of patients with mechanical ventilation, Renew Group is working together with the LifeSignals Group to integrate their wearable medical biosensors, a patch that allows the remote monitoring of patients respiration rate, heart rate, ECG, and oxygen saturation (Sp02).
This technology partnership will provide a better treatment of the patient and monitoring of wirelessly transmitting the patient vital signs data directly in the Open AirVentGT fan, allowing the fan pumps to respond to the patient’s breathing rhythm, and of the requirements to complement the use of the standard pre-set algorithms, the company said.
“The fans play a pivotal role in the management of COVID-19 patients suffering from serious respiratory diseases. Our engineers are working to integrate medical care biosensor technology in AirVentGT fan that’s going to improve the treatment and care of the most critical COVID-19 patients,” said Surendar Magar, Ceo and co-Founder of LifeSignals Group.
