In order to facilitate patients who are advised to stay on a ventilator, a new mini ventilator machine has been developed. Reportedly, it is the world’s cheapest and smallest ventilator, developed by AIIMS in collaboration with a private company and can easily fit into your pocket.

The invention is the brainchild of Dr Deepak Agrawal, professor in the department of neurosurgery at AIIMS, who was joined with Diwakar Vaish, a robotics researcher at A-SET Robotics to make the device.

The device is almost 450 times smaller than the conventional ventilators and can be moved around easily.


This ventilator is easy to use and will be soon available in the market for a price of less than Rs 15,000.

Dr Agrawal informed that they are using the ventilator on some patients as pilot.

Currently, a basic ventilator is priced above 2.5 lakhs in the market.

This new mini ventilator can be controlled with an Android app. To adjust air supply for normal breathing of the patient it uses an artificial intelligence algorithm.

Dr Agrawal further informed that, “It works by pushing the atmospheric air into the lungs of the patients who cannot breathe on their own. The disposable ventilators currently in use also push in air, but they do it at a fixed frequency that does not necessarily match the patient’s breathing pattern, which may cause low oxygen saturation. This device synchronises ventilator air support with the normal breathing pattern”.
