Article Abstract

Throughout history there have been epidemics and pandemics of all kinds, however the most recent ones have been respiratory diseases that have had a significant effect on the society and that have caused high mortality rates. The preventive measures to minimize the risk of contagion by contact with infected surfaces include ergonomic accessories including personal protective equipment (PPE) to prevent hands to be in contact with surfaces that could be infected by viruses, bacteria, fungi, etc., thus avoiding infection by the usual entry routes (mouth, nose, and eyes) to the human body of highly contagious diseases such as COVID-19. The collaborative manufacture of these safety accessories at the site of consumption is a current option that minimizes infectious diseases and reduces costs. Accessories such as the so-called "ear saver" and "anti-contact keys" can be produced by 3D printing with a general CAD/CAM and allow users in hospitals, and schools, such as medical and teaching staff and society in general to extend the life of N95 respirator fasteners (protective masks) and avoid contagion. These devices can be used to open doors and windows and control elevators, etc. The accessories can be optimized ergonomically for individual use by providing a custom design. The collaborative manufacture of these elements allows the product design stages to be carried out autonomously. In the manufacturing stage, 3D printers can be used to produce the devices at the point of use, thus saving on transport and distribution costs. This paper describes a comparative analysis of their design, manufacture and use in hospitals, schools, universities, and commercial areas with the aim of improving the current design.
