Project Summary

The covid-19 pandemic has produced critical shortages of ventilators worldwide. There is an unmet need for rapidly deployable, emergency-use ventilators with sufficient functionality to manage covid-19 patients with severe acute respiratory distress syndrome. Here, we show the development and validation of a simple, portable and low-cost ventilator that may be rapidly manufactured with minimal susceptibility to supply chain disruptions. The ventilator delivers breaths by compressing a conventional bag-valve mask (BVM) with a pivoting cam arm, eliminating the need for a human operator for the BVM. An initial prototype was built out of acrylic, measuring and weighing. It is driven by an electric motor powered by a DC battery and features an adjustable tidal volume up to a maximum of 750 ml. Tidal volume and number of breaths per minute are set via user-friendly input knobs. Through this prototype, the strategy of cam-actuated BVM compression is proven to be a viable option to achieve low-cost, low-power portable ventilator technology that provides essential ventilator features at a fraction of the cost of existing technology.  The covid-19 pandemic has produced critical shortages of ventilators worldwide.

Project Objectives

To meet the increasing demand of mechanical ventilators due to COVID -19 and omicron. To provide low cost alternative to ventilators.

develop a very easy to operate system so that any less experienced person must be able to operate it with ease.

A portable machine will be use in;

Hospitals & Clinics

Ambulances

Homes

Project Implementation Method

The project is composed of both hardware and software. The hardware mechanical part is being directed by the software code throuh the help of microcontroller. The microcontroller will take the values of the parameter of the patient breathing. Also it will give the output signal accordingly to give required pressure of air through motor. The oxygen mask will be attached at the end of the tube to take the air in. The pressure transducer tube will be attached to the tube just below the mask. Microcontroller will give signal to the motor and motor will pump air accordingly.

Benefits of the Project

•The main electronic body of the project is the set of multiple feedback control systems.

•The system is based on the set of sensors use to take the inputs of different parameters. The sensors are being attached to the microcontroller.

•The microcontroller is fed with the code with standard values of the parameters.

•The code checks if these parameter are running normal according to the age of the patient.

•If it is normal the diagnosis will be completed and it will show the sign of zero illness.

• Otherwise, the it will provide with the oxygen or the required treatment.
