Tezpur: Tezpur University’s Electrical Engineering Department have designed a portable ventilator to help fight the ongoing oxygen crisis.

The USP of the machine is that it has Internet of things (IoT)-based features like monitoring of patient activity and controlling parameters of ventilator through an app and is affordable. Depending on its features, the machine costs between Rs 8,000-15,000.

A ventilator is an essential instrument for patients who are unable to sustain the level of ventilation necessary to maintain the gas exchange functions.

The initiative was part of a project, awarded as the ‘Best Innovative Engineering Idea’ under the banner of Prof. Aparna Kumar Padmapati Annual Scholarship from Assam Engineering College Class 88 Foundation for 2020-21.

Bihung Muchahary, Aniket Raj, Manish Kumar and Ankita Das are working on the project under the guidance of Chiranjit Adhikary, ex-Guest Faculty and Firdausa Ahmed, Guest Faculty member and the project is supervised by Prof. Soumik Roy, Head, Department of Electrical Engineering.

Prof Roy explained: “The purpose of the project is to design a portable mechanical ventilator by automating the operation of ‘Ambu Bag‘ with volume control ventilation which can be used in respiratory failure”.

An ‘Ambu Bag’ is a hand-held device commonly used to provide positive pressure ventilation to patients who are not breathing adequately or have a severe problem in breathing.

“Another important objective of the project is to implement Internet of things (IoT) based features like monitoring of patient activity and controlling ventilator parameters through an App”. The prototype we designed is sufficiently economical, and by using IoT as a remote controlling feature, one can control and monitor the ventilatory parameters through devices like mobile phones, tab and computers. Besides, it will prevent both the clinicians and the doctors from getting infected from airborne transmission”, Prof. Roy added.
