A research team from the Madurai Kamaraj University (MKU) has invented a new, simple and modernized ventilator cum respirator device (LIDS-VR) that would help prevent the spread of coronavirus while providing continuous oxygen supply for frontline workers, infected patients and healthy people.
Vice chancellor (VC) of MKU, professor M Krishnan, said a team of experts - Dr T Arockia Doss, department of physics and Dr B Ashokkumar, department of genetic engineering, invented this device (LIDS-VR). They was demonstrated the device in front of Dr N Sivasubramanian, former senior scientist, Indian Space Research Organisation (Isro), who has appraised the invention.

With immunity becoming the new obsession, traditional herbal concoctions and innovative boosters are finding takers

LIDS-VR works by providing a high concentration of oxygen into the available air within the device by oxy scavenger, when an AC electromagnetic field is applied. More than 33% oxygen is generated inside LIDS-VR within 11 seconds. It is portable and weightless and also has nano-circuits with sensors.


There are two types of LIDS-VR available (with and without sensors by mobile applications), which have the ability to automatically regulate according to the patient’s requirement, a statement said.
Normally, a respirator is used to protect a person, who is working in an area with chemicals or germs and protect the respiratory system by filtering out dangerous substances from inhaled air and maintain a constant pressure in the lungs.
A ventilator on the other hand circulates fresh air by a mechanized device that enables the delivery or movement of air and oxygen into the lungs by an extra O2 cylinder and electric motor power. Though portable ventilators are available an O2 cylinder has to be carried along with it or use a high-cost membrane for separation of oxygen.
