IIT Ropar develops Jivan Vayu as an alternate of CPAP machine

IIT Ropar has developed a device called “Jivan Vayu” that can be used in place of a Continuous Positive Airway Pressure (CPAP) machine.
According to a press release, this is the first device of its kind in the country that operates without electricity and is compatible with both CO2 cylinders and oxygen pipelines in hospitals. These features are not available in conventional CPAP machines.

The device is intended to maintain a FiO2 (fraction of inspired oxygen (FiO2) is the oxygen concentration in the gas mixture) of greater than 40% while maintaining a PEEP (positive end-expiratory pressure) of 5-20 cm H2O.

Additionally, the device incorporates a viral filter with a 99.99 percent viral efficacy at the air entrainment end. The viral filter ensures that no pathogens from the surrounding environment are introduced into the entrained air. The device’s design specifications were optimised for an accelerated flow rate of up to 60 LPM (from an oxygen cylinder), and it was manufactured using 3D printing.

The device is designed for use with a 22 millimetre (mm) closed circuit CPAP machine and can be customised. The device’s inlet end must be connected to the oxygen supply oxygen cylinder via a nozzle/adapter. A viral filter is inserted into the air entrainment window and connected to the out end of a 22mm CPAP tube, which is then connected to the CPAP Mask and PEEP Valve. The regulator at the cylinder end and the PEEP valve can be used to control the flow and positive pressure, respectively. Leakproofing has been designed and tested into the device.

Summer increases electricity demand, and the distribution system, which is already frail or poorly constructed, becomes overloaded, resulting in power outages. Rural India is likely to be the hardest hit, with government data indicating that nearly 39,000 health sub-centres operated without electricity in rural India.

Mechanical testing and development took place at Dr. Khushboo Rakha’s ‘Advanced Materials and Design Lab,’ which is directed by Dr. Khushboo Rakha, Assistant Professor of Metallurgical and Materials Engineering. Mr. Suresh Chand, Faculty Incharge, Rapid Prototyping Lab, Siemens Centre of Excellence at Punjab Engineering College, Chandigarh, collaborated with the team to 3D print the device.

The device is currently undergoing medical testing, and the team is seeking industrial collaboration to expedite the commercialization of this life-saving device.
