Novel Coronavirus

COVID-19 is caused by a coronavirus called SARS-CoV-2. It is thought to spread from person to person, mainly through respiratory droplets produced when an infected person coughs or sneezes. Spread is more likely when people are in close contact with one another (within about 6 feet) by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes.

COVID Virus makes it hard for the patient to breath and it constantly gets worse, until the afflicted person can no longer breathe by themselves. The current solution is to attach the patients to a mechanical ventilator, which is running hospitals dry as patients are flooding in.

Due to these reasons, we are opting to direct our efforts toward modifying existing manufacturing plans and improving these low-cost ventilator designs to better accommodate real patients.

Our Goal

We are planning to create low cost open-source ventilators and send them to a city across the border to Mexico. This city is Mexicali, Baja California, Mexico, which has about a million inhabitants. The city has about 20 ventilators and 200 ventilators across the entire state. They are in desperate need of equipment and our team wants to help by sending them ventilators.

Ventilator Design Requirements

Currently, low-cost ventilators are being produced in an effort to assist with the COVID-19 effort, but cannot be employed for a number of reasons. As one of our senior project due to this widely spread of the virus, we have decided to use new MIT ventilator called "MIT E-Vent" to help people from around the world, specially people in Mexico.

The design requirements for the ventilator are:
1. Variable from 6 to 40 breaths per minute
2. Volume of air into lungs between 200 - 800 mL based on weight of patient
3. Inhale/Exhale time ratio of 1:2
4. Maximum airway pressure of 40 cm H2O at all times
5. Failure conditions notifies user by alarm

The essential components for a low cos ventilator are included:
1. BVM (Bag valve mouth)
2. Spirometer
3. Controllers
4. Pressure/Volume Sensors
5. Linear Actuator
