DEVICE TO PROTECT FROM AIRBORNE PATHOGENS

Smart overview of the Invention

A novel wearable device combines an air disinfection chamber with a slidable face shield, designed to be mounted on a common headwear item such as a baseball cap. The key component of this device is the air disinfection chamber, which utilizes ultraviolet LEDs at germicidal wavelengths to neutralize airborne pathogens, ensuring the user inhales pathogen-free air. Additionally, the device can operate in a reverse mode to protect others by filtering exhaled air from potentially infected users.

Patent Background

This application builds upon previous patents focused on portable air disinfection devices, particularly those developed during the COVID-19 pandemic. The technology is primarily aimed at inactivating the SARS-CoV-2 virus but is also effective against other airborne pathogens like influenza and tuberculosis. The invention addresses the need for versatile protection that can adapt to various environments and user health conditions.

Transmission Pathways

The device targets multiple transmission pathways of airborne viruses, emphasizing aerosol transmission as a primary concern. Aerosols are tiny particles that can linger in the air for extended periods, posing a significant risk in indoor and poorly ventilated spaces. The wearable device aims to mitigate these risks by filtering and disinfecting the air surrounding the user.

Limitations of Masks

Traditional face masks have several drawbacks, including improper fit, discomfort, and limited protection against airborne pathogens. Masks can obstruct breathing, fog glasses, and fail to protect areas like the eyes. They also hinder communication and are impractical for extended use or activities like eating and drinking. This invention offers an alternative that overcomes these limitations while providing effective pathogen protection.

Need for Improved PPE

The development of this device addresses the demand for lightweight, comfortable personal protective equipment (PPE) suitable for everyday use. It is particularly beneficial for high-risk individuals such as the elderly or those with compromised immune systems who require enhanced protection against COVID-19. By offering improved comfort and usability, this invention aims to provide better protection without the drawbacks of existing PPE like PAPRs or traditional masks.
