A shortage of intubation devices is a critical concern for the COVID-19 pandemic. The purpose of this open source hardware project is to develop designs whereby makers can assist with the fabrication of intubation devices that could be used by medical personne.

Hello Open Respirator Team, I’m working with UK GOV to find designs for ventilators that are designed for resource constrained settings to be adapted for manufacturing en mass. We have the health engineering team at UCL standing by to help take designs and make them manufacturing ready. We’ve published an open call for tech teams to use to make themselves known to us, which can give you the full rundown of what we’re looking for, but to keep things simple I’ve pasted our core technical requirements below. We came across your work on the Coronavirus TechHandbook page and thought you might be interested in this project.  Please help us spread the word by: Sharing with your networks: http://bit.ly/frontiertech4COVIDactionClicking here for a pre-loaded tweet to tweet about the call Pace is imperative. The need is urgent. We’re working with tight deadlines and need your help to get the message out and save millions of lives.  Call for applications: 16th of March 2020  Applications close: 24th of March 2020 Final Selection: 25th of March 2020  Any questions or comments, contact the team at COVIDaction@hellobrink.co  Thank you,Alex

CORE TECHNICAL PARAMETERS The RMVS must: Be reliable.  It must work continuously without failure (100% duty cycle) for blocks of 14days - 24 hours a day.  If necessary, the machine may be replaced after each block of 14 days x 24 hours a day use. Provide at least two settings for volume of air/air O2 mix delivered per cycle/breath.  These settings to be 450ml +/- 10ml per breath and 350ml +/- 10ml per breath.  Provide this air/air O2 mix at a peak pressure of 350 mm H2O. Have the capability for patient supply pipework to remain pressurised at all times to 150mm H20. Have an adjustable rate of between 12 and 20 cycles/breaths per minute. Deliver at least 400ml of air/air 02 mix in no more than 1.5 seconds.   The ability to change the rate at which air is pushed into the patient is desirable but not essential. Be built from O2 safe components to avoid the risk of fire and demonstrate avoidance of hot spots. Be capable of breathing for an unconscious patient who is unable to breathe for his or herself.  Ability to sense when a patient is breathing, and support that breathing is desirable but not essential. Be able to supply pure air and air O2 mix at a range of concentrations including at least 50% and 100% Oxygen.  Oxygen shortages are not expected, but the ability to attach a Commercial Off The Shelf (COTS) portable O2 concentrator machine may be a useful feature.   Support connections for hospital Oxygen supplies – whether driven by piped or cylinder infrastructure Be compatible with standard COTS catheter mount fittings (15mm Male 22mm Female) Fail SAFE, ideally generating a clear alarm on failure.  Failure modes to be alarmed include (but are not limited to) pressure loss and O2 loss. -- Alex Losneanu Innovation Manager, Brinkhellobrink.co +44 744 981 3249 Our latest thinking on Behavioural Innovation on the blog We are hiring!
