Innovation Description

The oxygen supply was a serious issue during the COVID pandemic. Keeping that in mind, a student created a smart nebulizer that can operate without the use of electricity. Oxyneb can nebulize an asthmatic patient.  A manually revolving flywheel powers its dual piston motor. The piston cylinders draw air through an air filter (which removes dust) and silica gel (which removes moisture) to provide a 5LPM air flow. This pressurized air is forced into an air reservoir before being pushed into a nebulizing chamber to transform liquid medicine into a breathable aerosol. Dry air is pushed into the Zeolite Chamber by the second piston. Due to an orifice near the chamber's outflow, air is pressured there. N2 molecules stick to the Zeolite Sieves at 20-22 PSI, while O2 molecules flow out of the chamber and into the air reservoir. When the pressure rises to 30-35 PSI, a weight pressure valve opens, releasing the stuck N2 and restoring normal air flow to the chamber. The valve closes, and the cycle begins all over again. The combined air from both pistons results in a 30-35 percent O2 concentration in the reservoir. Studies show that using O2 enriched air to nebulize asthma patients provides superior treatment and this device will play a critical role in it.
