Design and Implementation of a Helmet-based, Noninvasive CPAP Devices for COVID-19

Abstract

The world is passing a terrible time while lives are despairing due to coronavirus. In Covid-19, most of the patients suffer from low oxygen saturation. Different types of devices are used to increase the oxygen level. This paper discusses a helmet-based Continuous Positive Airway Pressure (CPAP) device’s design and implementation. A blower generates positive pressure, while a pressure sensor adjusts the required pressure. A TFT display is used to monitor the data, and two rotary encoders are used to set the required value. Two Arduino boards are used as real-time and user interface controllers. The hardware simulations and PCB designs are done in the Proteus software. The mechanical body of the CPAP device was designed in Solidworks software. A helmet is connected to the CPAP, also designed in the Solidworks software. The oxygen mixed pressurized air goes through the pipe to the helmet. Finally, the cost of the device is also presented in this paper.
