Construction of Two Box-Like Head-and-Face Shields by Japanese Origami Folding for Use During the COVID-19 Pandemic.

A worldwide shortage of personal protective equipment during the COVID-19 pandemic has led to the development of new alternatives. We introduce two new disposable box-like head-and-face shields constructed using Japanese origami-style folding. The design comprises a single sheet of thick paper and a shield made of a thin, transparent plastic sheet. The first design, Model 1, is a head-and-face shield designed to cover the wearer's head and neck. Model 2 was designed to solve the problem of heat and moisture buildup inside the shield. This version can be used as face shields for patients, and it allows clinicians to collect swabs from the nasopharynx for virus detection via polymerase chain reaction through pre-cut incisions near the nasal orifices. These two new box-like face shields are excellent alternatives to traditional face shields because of the low cost, compatibility with mass production, lightweight, and disposability.
