Coronavirus: An Indian-American couple develops a low-cost ventilator | Instant News


Indian-American couples have developed low-cost portable emergency ventilators that will soon enter production and will be available in India and developing countries to help doctors deal with COVID-19 patients.

Driven by the lack of adequate ventilators during the coronavirus pandemic, Devesh Ranjan, a professor and associate chair at the prestigious George W Woodruff School of Engineering in Georgia and his wife Kumuda Ranjan, a family doctor in Atlanta, developed an emergency ventilator from the prototype concept in only about three weeks.

“If you can scale, it can be produced (cost of goods) in less than USD 100. Even with a price point of USD 500, they (producers) will have enough money to ensure that they produce enough profit in the market,” Professor Ranjan notify PTI.

He said this type of ventilator, on average in the US, costs USD 10,000.

Ventilators take over the body’s respiratory processes when the disease has caused the lungs to fail. This gives the patient time to fight the infection and recover. However, Ranjan explained that it was not an ICU ventilator, which was more sophisticated and more expensive.

Open-AirVentGT has been developed to deal with acute respiratory distress syndrome, a common complication for COVID-19 patients that causes the lungs to stiffen, which requires breathing to be helped by a ventilator, he said.

The ventilator developed at the Georgia Institute of Technology uses electronic sensors and computer controls to manage key clinical parameters such as respiration rate, tidal volume (the amount of air entering and leaving the lungs during each cycle), the ratio of inspiration and expiration, and pressure on the lungs. lung.

“The whole purpose of the project is to create a low-cost emergency ventilator that provides such control to doctors,” Dr. Kumuda told PTI, noting that there would be a shortage of global ventilators given the large spread of the coronavirus, which has thus far killed more than 345,000 people worldwide and infects more than 5.4 million.

In the United States as of Monday, more than 98,000 Americans have died and nearly 1.7 million people tested positive. Scientists race with time to develop vaccines or come out with therapeutic treatments.

Born and raised in Patna, Bihar, Ranjan obtained a bachelor’s degree in engineering from Regional Engineering College, Trichy was followed by Masters and PhDs from the University of Wisconsin-Madison and has taught at Georgia Tech for the past six years.

Kumuda moved with his parents to the US from Ranchi when he was six years old. He did medical training and residency in New Jersey.

Both Ranjan and Kumuda said that India has the potential to become a global manufacturing of low-cost ventilators and exports worldwide at an affordable rate for all.

Professor Ranjan said that low-cost ventilators had been developed taking into account the requirements of countries such as India and countries in Africa, where affordability care was a huge factor in providing health services to the public.

The idea is to develop lost cost ventilators, which can be produced very easily using supply chains that are already available in India, he said.

Rajan said that the team had been approached by Georgia Tech alumni in Ghana and India to create production lines in their country.

“This impact could be significant if other parts of the world are affected by the COVID-19 pandemic. Having equipment that can be made quickly where it is needed and with the type of control system needed by doctors can really help overcome the worldwide impact of this virus,” he said .

The prototype is now being developed into a tangible product by the Singapore-based Renew Group, led by Ravi Sajwan, an Indian-American from Uttarakhand.

“We have built a wide network of collaborations with a single focus on getting more ventilators into the most unprofitable health system in the world to help doctors and patients dealing with COVID-19,” Sajwan said.

Overcoming the critical shortcomings of low-cost mechanical ventilators is the main focus of the Renew Group, which works with a group of companies and affiliates who are committed to accelerating the manufacture and distribution of medical-grade ventilation devices, Open-AirVentGT for hospitals and remote facilities in less developed countries luck included India, Vietnam, Sri Lanka and Cambodia, the company said in a statement.

To maximize the effectiveness of treating patients with ventilators, the Renew Group is working with LifeSignals Group to integrate medical biosensors that can be used, disposable fillings that allow remote monitoring of patients on respiratory rate, heart rate, ECG and oxygen saturation (Sp02).

This technology partnership will provide enhanced patient care and monitoring by transmitting patient vital signs data directly to the Open-AirVentGT ventilator, which allows the ventilator pump to respond to the patient’s respiratory rhythm and requirements that complement the use of predetermined standard algorithms, the company said.

“Ventilators play an important role in the management of COVID-19 patients suffering from severe respiratory conditions. Our engineers work to integrate medical biosensor technology into the Open-AirVentGT ventilator which will improve the care and care of the most critical COVID-19 patients,” Surendar Magar said. , Chief Executive Officer and co-founder of LifeSignals Group.
