Design and Development of Mobile Operated Portable Ventilator.

Abstract

This paper describes the concept of full function portable ventilator, which have low cost, minimum weight, compact, small-sized. It can easily operate by mobile application and that application able to measure PEEP pressure, tidal volume and flow rate. The essential components used are stepper motor, rack and pinion, motor driver, Nod MCU, Acrylic sheet, Battery etc. There are some open sources Hardware ventilator (OSM-MVs) have been used during COVID-19 Pandemic. The ventilator device breaths by compressing a convention bag-valve mask (BVM) with a help of Rack and Pinion, that eliminate the need of human operator for the BVM. Initially the prototype is built out by Acrylic Sheets, it is work as thermal insulator and it's approximately 20% better than glass. The measurement of portable ventilator is 9.8*4.7*7 inches (250*120*180) mm and weighting 2.20lbs (1.5kg). It is driven by the motor driver powered by a VDC battery. The sensors are used to operate it by a mobile operation for measurement of tidal volume, PEEP pressure etc. The design is made up of CAD software and also makes Ansys for this device. The experimental results taking after testing on artificial lung that where the Positive Inspiratory Pressure (PIP), respiratory rate (RR), tidal volume, Positive end- expiratory pressure (PEEP) and its accuracy exceeding human capabilities in BVM.
