The Challenge
The ongoing COVID 19 pandemic has revealed the PPE supply chain shortages as well as many deficiencies of the existing personal protection equipments.
Positive Air Pressure Respirators (PAPR) are expensive, bulky thus not as comfortable to use, and are not reusable.
Surgical masks do not provide full-face protection, are often worn incorrectly, are uncomfortable when worn for long periods of time, and intended for single use.
N95 masks require a fit test and are often worn incorrectly.
The Solution
The U-visor is a positive air pressure equipment that has a fan and a concealed ultraviolet light chamber to circulate and sterilise the air surrounding the wearer. The prototype of the UV chamber received >99% efficiency in testing by Sandia National Laboratories against a MS2 surrogate virus.
The device was created with front-line workers from the high trafficking areas in mind. These include:
- The Food Processing Industry;
- Nursing Homes;
- Educational Institutions;
- The Travel Industry;
- Storage Buildings;
- The Retail Industry and more.
While keeping them safe, the UVisor is also comfortable to use, has a magnetic detachable visor that can be easily removed if needed, it’s lightweight, and 100% reusable. The user can easily decontaminate the helmet by wiping it down with conventional disinfectant. The device comes with an in-built battery that can be charged through a standard USB cable, and holds up to 6 hours of charge. As compared to PAPR, U-visor has no external hoses, power and filter units.
The device is designed with the idea of repurposing commonly found materials thus ensuring production and manufacturing are at an affordable price. This helps fill in the gaps in the global supply chain of face visors rather than completely replacing it.
The IUVA (International UV Association) Executive Committee rewarded Helpful with special recognition for the team’s effort on the UVisor Project.
