St. Petersburg engineers have designed and 3D-printed a special protective helmet for doctors working with COVID-19 patients. It provides 99.9% protection from the virus, is low weight and has an integrated ventilation system. Denis Golubev, one of the developers, told about the invention speaking on Saint-Petersburg TV Channel.
The helmet has a transparent screen and a compact ventilator in its upper part making it easier to breathe.
‘It took us a lot of time to find a lightweight ventilator that could provide long and safe operation without making noise and vibration. You won’t be able to work for several hours with something vibrating over your head. The main task was to make it comfortable for doctors who are working 24 hours a day in protective overalls in the red zone,’ Denis Golubev explained.
Parts of the helmet were 3D-printed. This technology allows of making changes to constantly improve the product. At first, the helmet weighed 1.5 kilos, then the developers brought the weight down to 700 grams. The helmet comes with protective eyeglasses, which do not get misted due to the ventilation system.
Doctors at City Hospital No2 have already been able to test the new helmet. The developers hope medics in other clinics will also find it useful.
