A simple, low-cost, but robust, ventilator to help critically-ill Covid-19 patients has been rapidly designed at Cranfield University, external in Bedfordshire and built in the US in a matter of days.
The makeshift Bag Valve Mask (BVM) ventilator, which can serve two patients at once, can be manufactured at scale due to its flat-pack design, costing less than £75 ($100) per unit. Kits can be shipped and then reassembled where needed.
The Cranfield team said it sent an initial design to Georgia Tech, external, Atlanta, within five days of getting the brief and a small batch has already been assembled for testing.
Prof Leon Williams, from Cranfield, said: "We focused on creating something that can be mass-produced using water-jet or laser cutting, and modular in design to make it easy to assemble and switch out parts."
Associate Prof Shannon Yee, from Georgia Tech, said: "What’s unique is that we have two BVMs per ventilator, which allows two people to breathe with each device that is built."
The research team said the design should be available to manufacturers as quickly as possible.
