Wheeled Sterilization Unit
The COVID-19 pandemic exposed a critical gap in readily available disinfection methods. This innovative UV disinfection device addresses this challenge by offering a dry and material-safe solution. Unlike existing methods that may damage equipment or be ineffective, UV disinfection eliminates pathogens without harming delicate surfaces. Developed using readily available materials, the technology demonstrates its rapid deployment adaptability during crises. Furthermore, the technology builds upon established scientific knowledge regarding the effectiveness of UV radiation against viruses. This technology offers the potential to expand access to disinfection beyond traditional healthcare settings, potentially impacting public health efforts positively.
The outbreak of COVID-19 emphasized the critical need for improved disinfection methods, particularly in public transportation systems and hospital rooms. While existing solutions like bleach or alcohol-based sanitizers work well on surfaces, they present significant challenges in these environments. Firstly, these liquids can damage delicate materials and electronics commonly found in these settings. Secondly, manual disinfection using liquids is a time-consuming process, hindering efficiency. Hence, there was a strong need to develop a dry, rapid, and material-safe disinfection method for large areas.
- This invention offers a dry disinfection method, unlike some methods that can damage equipment or be ineffective (alcohol-based sanitizers/bleach on seats).
- Experiments using MS2 phage demonstrate the unit's ability to eliminate the pathogens within a 1-meter radius after 15 minutes of exposure by delivering a sufficient UVC dose.
- Scientific research supports the effectiveness of ultraviolet C light in inactivating various emerging viruses, including severe acute respiratory syndrome coronavirus, Crimean-Congo hemorrhagic fever virus, and Nipah virus. This suggests the potential for the unit to be effective against a broader range of pathogens beyond those directly tested.
- Mobile Design: The unit is mounted on a wheeled base for easy maneuverability, allowing for disinfection in various locations.
- UV Light Source: Four 36W UVC lamps are positioned vertically within the unit to provide comprehensive UVC exposure throughout the target space.
- Power Supply: The UV lamps are powered by AC chokes (electronic ballasts) that operate on a standard voltage range of 220-240 volts at 50 Hertz. A long power cord connects to an external power source outside the disinfected area.
- Safety and Control: For operator safety, the unit is designed for external operation. A timer knob and indicator light are conveniently located on a metal control box mounted on the wheeled base. This control box allows users to set desired exposure times and monitor power status.
This user-friendly design offers the potential to expand access to disinfection beyond traditional healthcare settings, potentially impacting public health efforts positively. The first prototype was deployed in IITB Hospital to sanitize spaces during the first wave of COVID-19. Subsequent licensed versions have been available at cheap prices on e-marketplaces. These efforts by the inventor were highlighted in multiple newspapers at the time of the invention of this technology.
This large-scale germicidal UV sterilization unit offers a powerful disinfection solution for large spaces. It can effectively disinfect operating rooms, patient rooms, and isolation wards between patients in healthcare facilities. Public transportation can benefit from this unit's ability to quickly sanitize buses, trains, and airplanes during downtime between passenger use. Additionally, manufacturing facilities can leverage this technology to disinfect production lines and equipment during cleaning cycles, promoting a cleaner and safer working environment.
