This wire band is a first prototype of a low-cost face mask band to address the lack of 3D printers and the overall cost of printing bands in El Salvador. This design takes only two minutes to make and can be made anywhere to ensure a better fit and a safe use of protective equipment during the COVID-19 pandemic.

This design is intended to substitute 3D printed designs such as the one currently recommended by the NIH in order to ensure access to people in settings where 3D printers are not available, and to reduce dependency of providers for plastic bands.


Assembly[edit | edit source]

The wire is simply bent in the shape shown in the photo. I experimented with other shapes such as a ring. Once a design is proven comfortable, and there is a demand for them, these bands could be assenbled with the use of metal guides to reduce the time and standardize sizes and shapes.

Use[edit | edit source]

The band is worn behind the head as it is shown in the image. This solution can be used to design other wire shapes to be more adaptable and safe to use in a medical setting.
