OPENVENT-BRISTOL V3.0

After feasibility has been proved, a final design will be made which will need to be successfully tested against the MHRA requirements before we can apply for medical device clearance. 

The UK National Physical Laboratory will conduct this testing.

Although this project is open source this design is not permitted for anybody to make themselves as this will not provide sufficient quality control needed for medical product clearance when it gets to that stage, instead we will need to collaborate with manufacturers.

Please take a moment to share our work and consider helping fund our design if you can.

We are a team of volunteers and we are not being paid for the work we
are putting in to this project.

We require funding for building the next set of prototypes for testing against the MHRA requirements

All donations received will go towards; buying parts & materials and production of a small number of test units (unit costs will reduce quickly with higher volumes).

ADVANTAGES OF OUR DESIGN

Ventilator capacity is improving in countries that can afford to make non-emergency use ventilators, but these more complex designs take time to scale up, use specialist components and are costly, so these are not a suitable solution for all countries. We are working to address the ventilator shortage in the developing world.  The design is based on a hand pumped ventilator called an ambu-bag (or BVM), these low cost devices are readily available in most countries health care systems and crucially already have medical clearance. 

There are lots of incredible teams out there designing ventilators, and the worldwide ventilator shortage is not going to be solved by one ventilator design. We are working to meet an unmet need and we go by the following values:

Based on an ambu-bag

Ambu-bags exist readily in most countries healthcare systems with pre-existing medical approval for manual ventilation.

Rapid manufacture

Made from readily available materials and production processes to enable rapid manufacture at low cost.

Can be used anywhere

Not dependent on compressed airline which may not be available in hospitals with less resources (oxygen is separate).

CAN BE USED ANYWHERE

Bag compression can be monitored through transparent panel for feedback.

OUR JOURNEY

Our first open source basic mechanical design concept is published.

Version 2.0 design is tested at National Physical Laboratory

Version 2.0 open source design is published

Build two Version 3.0 prototypes using 3D printed flow sensors

Software written for PCV and adaptive ventilation modes

Testing of the final design at NPL to MHRA requirements

Build 10 prototypes & receive CNC machined prototype flow sensor

Begin 24/7 life test on prototypes, document design and post PR/press articles to gather interest in final design
