Coronavirus: India’s race to build a low-cost ventilator to save Covid-19 patients

In an 8,000 sq ft (743 sq m) facility in the western Indian city of Pune, a bunch of young engineers are racing against time to develop a low-cost ventilator that could save thousands of lives if the coronavirus pandemic overwhelms the country’s hospitals.

These engineers – from some of India’s top engineering schools – belong to a barely two-year-old start-up which makes water-less robots that clean solar plants.

Last year, Nocca Robotics had a modest turnover of 2.7 million rupees ($36,000; £29,000). The average age of the mechanical, electronic and aerospace engineers who work for the firm is 26.

India, by most estimates, only has 48,000 ventilators. Nobody quite knows how many of these breathing assistance machines are working. But it is a fair assumption that all those available are being used in intensive care units on existing patients with other diseases.

About one in six people with Covid-19 gets seriously ill, which can include breathing difficulties. The country faces seeing its hospitals hobbled as others around the world have been, with doctors forced to choose who they try to save.

At least two Indian companies make ventilators at present, mostly from imported components. They cost around 150,000 ($1,987; £1,612) rupees each. One of them, AgVa Healthcare, plans to make 20,000 in a month’s time. India has also ordered 10,000 from China, but that will meet just a fraction of the potential demand.

The invasive ventilator being developed by the engineers at Nocca Robotics will cost 50,000 rupees ($662). Within five days of beginning work, a group of seven engineers at the start-up have three prototypes of a portable machine ready.

They are being tested on artificial lungs, a prosthetic device that provides oxygen and removes carbon dioxide from the blood. By 7 April, they plan to be ready with machines that can be tested on patients after approvals.

“It is most certainly doable,” said Dr Deepak Padmanabhan, a cardiologist at Bangalore’s Jayadeva Institute of Cardiovascular Sciences and Research, and a key advisor on this project. “The simulations on artificial lungs have been done and seem to work well.”

Inspiring story

The race to develop this inexpensive, home-grown invasive breathing machine is an inspiring story of swift coordination and speedy action involving public and private institutions, something not common in India.

“The pandemic has brought us all together in ways I could never imagine,” says Amitabha Bandyopadhyay, a professor of biological sciences and bioengineering at Indian Institute of Technology (IIT), Kanpur, and a key mover of the project.

The young engineers mined open source medical supplies groups on the internet to find information on how to make the ventilators. After securing permissions, it took them exactly eight hours to produce the first prototype. Of particular use, say doctors, were some designs by engineers at MIT. With imports stalled, the engineers picked up pressure sensors – a key component of the machine that helps supply oxygen to lungs at a pressure that doesn’t cause injury – from those used in drones and available in the market.

Local authorities helped open firms that stock components – each machine needs 150 to 200 parts – and made sure that a bunch of engineers who had returned home to Nanded after the lockdown were still able to travel 400km (248 miles) back to Pune to work on the machine.

Some leading Indian industrialists, including a major medical device-making company, have offered their factories to manufacture the machines. The plan is to make 30,000 ventilators, at around 150-200 a day, by the middle of May.

Social media influencers joined the effort. Rahul Raj, a lithium battery-maker and an IIT alumnus, crowd-sourced a group called Caring Indians to “pool resources and experience” to cope with the pandemic. Within 24 hours, 1,000 people had signed up. “We tweeted to the local lawmaker and local police in Pune to help the developers, and made contacts with people who would be interested in the project,” Mr Raj said.

‘No-frills machine’

Expat Indian doctors and entrepreneurs who went to the same school – IIT is India’s leading engineering school and alumni include Google chief Sundar Pichai – held Zoom meetings with the young developers, advising them and asking questions about the machine’s development. The head of a US-based company gave them a 90-minute lecture on how to manage production. A former chief of an info-tech company told them how to source the components.

Lastly, a bunch of doctors vetted every development and asked hard questions. In the end, more than a dozen top professionals – pulmonologists, cardiologists, scientists, innovators, venture capitalists – have guided the young team.

Doctors say the goal is to develop a “no-frills” breathing machine tailored to Indian conditions.

Ventilators depend on pressurised oxygen supply from hospital plants. But in a country where piped oxygen is not available in many small towns and villages, developers are seeing whether they can also make the machine run on oxygen cylinders. “In a way we are trying to de-modernise the machine to what it was barely 20 years ago,” says Dr Padmanabhan.

“We are not experienced. But we are very good at making products easily. The robots that we make are much more complex to make. But this is a life-saving machine and carries risk, so we have to be very, very careful that we develop a perfect product which clears all approvals,” said Nikhil Kurele, the 26-year-old co-founder and chief executive officer of Nocca Robotics.

In just a week’s time, India will learn whether they pulled off the feat.

I M Pei, the architect behind buildings including the glass pyramid outside the Louvre in Paris, has died aged 102.

Tributes have been pouring in, remembering him for a lifetime of designing iconic structures worldwide.

Pei’s designs are renowned for their emphasis on precision geometry, plain surfaces and natural light.

He carried on working well into old age, creating one of his most famous masterpieces – the Museum of Islamic Art in Doha, Qatar – in his 80s.

A pragmatic artist

Ieoh Ming Pei was born in Guangzhou in 1917, and moved to the US at the age of 18 to study at Pennsylvania, MIT and Harvard.

He worked as a research scientist for the US government during World War Two, and went on to work as an architect, founding his own firm in 1955.

One of the 20th Century’s most prolific architects, he has designed municipal buildings, hotels, schools and other structures across North America, Asia and Europe.

His style was described as modernist with cubist themes, and was influenced by his love of Islamic architecture. His favoured building materials were glass and steel, with a combination of concrete.

Pei sparked controversy for his pyramid at the Louvre Museum. The glass structure, completed in 1989, is now one of Paris’ most famous landmarks.

His other work includes Dallas City Hall and Japan’s Miho Museum.

“I believe that architecture is a pragmatic art. To become art it must be built on a foundation of necessity,” he once said.

He was won a variety awards and prizes for his buildings, including the AIA Gold Medal, the Praemium Imperiale for Architecture.

In 1983 Pei was given the prestigious Pritzker Prize. The jury said he had he “has given this century some of its most beautiful interior spaces and exterior forms”.

He used his $100,000 prize money to start a scholarship fund for Chinese students to study architecture in America.

Chinese students miss out on early places at MIT but what’s to blame for the change in fortune?

  • The prestigious college offered early admission to more than 700 students from around the world but none came from Chinese schools
  • Some analysts say Washington’s fears about espionage are to blame, while others put it down to China’s failure to prepare fully rounded youngsters

Unlike in the past, when at least a handful of students from Chinese schools made it through the early admission system, according to official results released by the college earlier this month this year there were none.

The news epitomised the falling success rate of mainland Chinese students seeking places at top US colleges in recent years amid growing uncertainty about immigration and visa policies, and the increased importance placed on applicants’ soft skills, some industry insiders have said.

The MIT offered early admission to more than 700 students chosen from 9,600 applicants from around the world. While five of them were Chinese nationals, they all graduated from US high schools.

“This is in line with the overall trend,” said Sun Rui, founder of Insight Education, a company based in the south China city of Shenzhen that helps Chinese students apply for undergraduate programmes in the United States.

“We feel that it’s harder each year to apply for top universities,” she said.

The number of students from Shenzhen who secured a place at one of the top four colleges in the US had been falling year by year, she said.

“Last year, a couple of students from Shenzhen made it to Stanford. This year it was none.”

While Chinese students had a reputation for getting high exam scores, Sun said they were often at a disadvantage when it came to soft skills, such as leadership and citizenship.

Chinese schools did not care about the latter, but American schools valued them greatly, she said.

As more Chinese children were being sent abroad to study at a younger age, those who went to US high schools were replacing those from Chinese schools when it came to undergraduate admissions, she said.

Li Li, whose daughter is at high school in Shanghai, said she had always wanted her child to apply for a top 20 US university but was now reconsidering.

“Given the current circumstances, your know, all the curbs on immigration and visa policy, I think I will consider another country, say Australia,” she said.

With richer parents eyeing better education abroad, Chinese students now account for about a third of all international students in US universities, according to official figures.

But potential applicants are being frightened away as Washington, under the administration of President Donald Trump, tightens it policies on Chinese students out of concerns about them being potential spies. The Financial Times reported recently that the White House had actually debated a proposal to stop all Chinese nationals from studying at US universities over such concerns.

New restrictions and requirements were introduced earlier this year for Chinese postgraduates majoring in science and engineering, as Trump accused China of stealing technology and intellectual property from US companies.

Sun said that an unpredictable admission policy was another reason for the drop off in Chinese students’ success in applying for top American schools.

“For example, unlike before, some top schools now require writing samples from international students, which to some extent shows they have worries about the applicants’ actual skills,” she said.
