Engineers join the fight against COVID19: how ventilation and masks are created at home

Starting with protective shields for healthcare workers and ending with valves for artificial respiration devices, enthusiasts make all this at home.

Now the technology is focused on fast movement and the creation of things without attracting large industries, which are already clogged with orders. This applies to protective face shields for healthcare workers; bathrobes for patients; oxygen masks; valves for artificial respiration apparatus and dividing tubes for mechanical ventilation apparatus (IVL), which may allow the use of one such apparatus for several patients.

Global voluntary networks of engineers, hackers, entrepreneurs and doctors have already formed in the world, which “hack” traditional medical devices and adapt existing versions or create new ones that can be made by any user on a 3D printer or even simply stitched.

In the Czech Republic, Prusa 3d printer company has a protective mask design project. Another Ultimaker 3D printer company has set up an online community to integrate 3D printer users with healthcare providers that may need help.

Take, for example, Helpful Engineering. There, over 3,400 volunteers delivered 35 projects over the course of several weeks, which had just been reviewed by a team of experts to test viability.

In Spain, a team of researchers assembled a home-made ventilator made of wood and aluminum, which uses a car wiper motor to inflate a manual resuscitation bag. It sounds desperate, but the team behind it has already been approached by two Spanish hospitals, where the situation is critical.

And an engineer from New York, Philip Sweeting, published a photograph of a 3D-printed splitter that he designed “for use with a ventilator to serve multiple patients with a single machine.”

Recall, the British company Bullit, which produces durable, resistant to mechanical damage phones, has placed in its new product an integrated thermal imaging camera that can be programmed to detect people with abnormally high temperatures at a distance. Thermal imaging cameras were used to detect fever during previous epidemics. Often these are more technologically advanced cameras of high cost.
