DIY Ventilator using Arduino with Blood Oxygen Sensing For Covid Pandemic

Project Title

Project Area of Specialization

Biomedical Engineering

Project Summary

The ventilator we here design and develop using arduino encompasses all these requirements to develop a reliable yet affordable DIY ventilator to help in times of pandemic.
We here use a silicon ventilator bag coupled driven by DC motors with 2 side push mechanism to push the ventilator bag. We use toggle switch for switching and a variable pot to adjust the breath length and the BPM value for the patient.
Our system makes use of blood oxygen sensor along with sensitive pressure sensor to monitor the necessary vitals of the patient and display on a mini screen. Also an emergency buzzer alert is fitted in the system to sound an alert as soon as any anomaly is detected.
The entire system is driven by arduino controller to achieve desired results and to assist patients in COVID pandemic and other emergency situations.

Project Objectives

- to develop DIY Ventilator using Arduino with Blood Oxygen Sensing For Covid Pandemic

- to build the hardware in order to analyze propsed system

- easy to use and has limited cost

- Widely used in Hospitals(Rural Areas)

Project Implementation Method

Our system makes use of blood oxygen sensor along with sensitive pressure sensor to monitor the necessary vitals of the patient and display on a mini screen. Also an emergency buzzer alert is fitted in the system to sound an alert as soon as any anomaly is detected.
The entire system is driven by arduino controller to achieve desired results and to assist patients in COVID pandemic and other emergency situations.

Benefits of the Project

- Easy to use it does not have heavy weight.

- there is no need of oxygen cylinders.

- have a suitable cost so every one can buy it.

- Can be used at home, school in emergency situations.

- Easy to operate it by just plucking the wire.

Technical Details of Final Deliverable

The main part Arduino which handles and controlls the all fuctions and also servo motor. it will send signals to every part.

Servo Motor is one of the most important part of this project which pushes the Silicon Air Breather Bag which pushes oxygen to the patient.

Silicon Air Breather Bag have the main role tp play, it takes the oxygen from air and then passes it to patient through the pipe lines.

LCD Display shows the total system in digital language with numbers of breath which the ventilator are supplying.
