Respirator with Air Blower and Air Quality Detector

This work is motivated by the challenges faced during the COVID-19 pandemic. Effective protection from the virus is needed. Masks is one way to protect from the virus. To support the efforots to control the spread of COVID-19 among the population, in this work we present an improved respiratory system consisting of a respiratory mask, air blower and a control system. Our design avoids some of the problems with available masks such as leak of unfiltered air and the irritation caused by these masks. To overcome this problem, the existing respirator is being modified to ensure user can breathe comfortably, no air gap on the side of respirator mask and respirator mask can measure air suction rate. Air blower will increase the air suction rate and sensor will detect the air quality and display it thru the monitor. User can monitor the air index surround them. A prototype is built. Testing of the prototype showed that the system functions as expected and achieves its objectives. On the downside, the prototype is heavier than existing products in the market. Further improvement in the design may lead to an improved version with reduced weight.
