Kerala engineering students develop portable ventilator

KOCHI: A group of final year biomedical students of Goverment Model Engineering College, Thrikkakara, has come up with an innovative low-cost ventilator design to support the government’s fight against Covid-19.

The design was made as part of ’emergency ventilator challenge’ organized by Dr A P J Abdul Kalam Technical University. It was rated among the five best ventilator designs by the varsity making it eligible for a financial support of up to Rs 20,000 for the product’s development.

According to college authorities, the students had come up with a mechanical ventilator design using a compressor with a respiratory feedback unlike those ventilators which are developed by students usually. They have developed the prototype using the available material in the college lab and the total cost was nearly Rs 5,000. Once the final product with industrial standards is out, it will cost around Rs 15,000.

“Most initiatives in this field are based on Artificial Manual Breathing Unit (AMBU bag) ventilation, which can give only respiratory support during emergency conditions. If feedback is not taken from the patient during the artificial ventilation it will further damage the respiratory system for patients with ARDS (Acute Respiratory Distress Syndrome), which is common among ovid-19 patients.
“In the prototype developed by the students, the drive mechanism for the ventilator is compressor output which is varied according to the respiratory feedback from the patient,” said Minimol B, associate professor, department of biomedical engineering, who is the mentor of the team.

The team consists of Dinakaran P S, Swetha T S, Athul Krishna Sadanandan, Abdul Sahad M S, Joel Roy, Salahudheen V M and Vineeth Vincent William P, all final year students. Now, they are awaiting funds to develop the final product for testing and certification.
