Prototype full face mask for the protection of Healthcare Workers from the Covid-19 risk by giobbi

Last crawled date: 4 years ago

To meet the needs of doctors and nurses, who work in contact with infected people in this Emergency-Covid phase, this helmet allows you to have your face free of both masks and visors, especially for those who wear glasses, avoiding uncomfortable phenomena such as fogged glasses.
A transparent PVC helmet with a 3D printed structure,
the project consists of 2 parts, the structure to hold the PVC around the head and a crescent element to be placed behind the neck with the passage of the closing elastic around the neck and with the connections for the air inlet pipe from the standard C-PAP respirator and the second tube with "non-return" valve for air outlet with the possibility of adding a soft bag as an expansion chamber.
The model is designed in several parts to be printed on a standard 3D printer with dimensions 20x20x20 cm. Transparent PVC can be heat sealed as it is suitable for use in gazebos or tents. The two elastics, with a knot on the forehead, hold the structure to the head and are tied posteriorly to the vertical rod on the back of the neck.
The concept of internal overpressure avoids any inflow of external air inside the helmet.
in case of emergency, the structure can also be made of "wire" of adequate thickness.
