The COVID-10 pandemic is seeing many hospitals run out of ventilators to treat patients, which is seeing designers create solutions like the 'Charlotte Valve' to help fill the shortage. The 3D-printed device works by being retrofitted onto a Decathlon scuba mask to instantly transform it into a ventilator that can be paired with wall-mounted oxygen distributors in hospitals. The valve has been patented by creators Isinnova S.R.L. to prevent it from being commercially produced and sold to keep it accessible for all.
The 'Charlotte Valve' is being encouraged by the designers to be 3D-printed by any designers who have resources to spare to help support healthcare endeavors and prevent those who need a ventilator to go without. The file has been made available along with instructions here.
