IIT Bombay student team develop low-cost mechanical ventilator Ruhdaar

Mumbai, Apr 27: A team of engineering students from IIT Bombay, NIT Srinagar and Islamic University of Science & Technology (IUST), Awantipora, Pulwama, Jammu and Kashmir have come forward to solve the problem of ventilator requirement by developing a low-cost ventilator using locally available materials.

Ruhdaar ventilator, as the team has named it, is the local answer to the worrying problem of non-availability of ventilators in the country, particularly Kashmir valley. Ventilators are an important component of the medical infrastructure required for treating infected patients, providing critical breathing support to those falling critically ill during the current Coronavirus pandemic.

The idea cropped up in the mind of Project head Zulqarnain, a first-year student of Industrial Design Centre, IIT Bombay, during his visit to his hometown Kashmir, when the institute closed due to the pandemic. On getting to know the ground situation as the pandemic progressed, he learnt to his dismay that there were only 97 ventilators in the Kashmir valley and sensed that there was a market for it as the shortage of ventilators had become a cause for concern for many locals.

So, Zulqarnain teamed up with his friends P S Shoib, Asif Shah and Shakar Nehvi from IUST, Awantipora and Majid Koul from NIT Srinagar. Taking assistance from the Design Innovation Centre (DIC) at IUST, the team has been able to design a low-cost ventilator using locally available materials. While their initial aim was to replicate a tried and tested design, as they began to work on it, they developed their own design of the ventilator.

Zulqarnain said "the prototype cost the team around Rs 10,000 and that the cost will be much lower, when we go for mass production."

He said that while high-end ventilators used in hospitals cost lakhs of rupees, "Ruhdaar provides necessary functionalities which can provide adequate breathing support necessary to save the life of a critically ill COVID-19 patient."

Talking about their next step, Zulqarnain said the team will now go for medical testing of the prototype. Once approved, it will be taken for mass production. "The effort is to make it amenable for production by small scale industry. The team will not charge any royalty for the product," he added.

Though beset with a lack of resources, the team tried many designs including a design developed by Massachusetts Institute of Technology, US. The team came up with their frugal design, considering the resource constraints. The design has been made using advanced software and the team is satisfied with the results, he said.

Asif, who is an alumnus of IUST and CEO of Symcore Technologies, said "the idea was to design and develop a low-cost alternative to the conventional ventilator. Our team has been able to achieve control of basic parameters such as tidal volume, Breaths per Minute and Inspiratory: Expiratory Ratio and to also monitor pressure continuously during its operation."

According to Dr Shahkar Ahmad Nahvi, Coordinator, DIC, IUST, the team of youngsters was driven by a desire to make a beneficial contribution to society in this hour of need. He finds the ventilator is functional from the engineering perspective but requires clearance and validation by the medical community.

Dr Majid H Koul, Professor, Department of Mechanical Engineering, IUST, says the frugal ventilator was developed using components available at DIC. Facilities at the Centre such as 3-D printing and laser-cutting technologies also were instrumental in the success of the prototype.

The Centre is an initiative of the Ministry of Human Resource Development, Government of India. (UNI)
