India’s IIT Ropar creates a substitute device for CPAP machine

The new device does not require electricity and can be modified to both oxygen cylinders and oxygen generation pipelines. 

Indian Institute of Technology (IIT) Ropar has created a device called ‘Jivan Vayu’ that can be used as an alternative for continuous positive airway pressure (CPAP) machine.

CPAP is a treatment technique used for patients with breathing difficulties during sleep, a condition called sleep apnoea. Using mild air pressure, the CPAP machine keeps the airways open to aid breathing.

It is also used for treating infants whose lungs are not fully developed.

The machine is required during the initial stages of Covid-19 disease to mitigate lung damage and help patients recover from the inflammatory effects.

The new CPAP device does not require electricity and can be modified to both oxygen cylinders and oxygen generation pipelines in hospitals.

It is said to be leak-proof, cost-effective and made for a 22mm CPAP closed-circuit tube. The CPAP delivery system can also be modified according to tube size.

Furthermore, the device runs even during power failures and could be used during the transport of a patient.

IIT Ropar Metallurgical and Materials Engineering assistant professor Dr Khushboo Rakha said: “This was the need of the hour during the present Covid pandemic when power supply is the key concern for saving lives of those on medical equipment such as ventilators and oxygen concentrators.

“It has an inbuilt viral filter at the air entrainment end which has a viral efficacy of 99.99%.”

The viral filter of Jivan Vayu prevents any pathogens present in the environment from entering the CPAP tube.

The device can offer high flow oxygen ranging from 20 to 60LPM while keeping a continuous positive pressure of up to 20cm H₂O, a press statement noted.

In addition, it is made to maintain a FiO2 of more than 40% with a positive end-expiratory pressure of 5cm to 20cm H₂O.

Produced through 3D printing, the device is set to enter medical testing and mass production.
