Design and Development of a low cost Ultraviolet Disinfection system to reduce the cross infection of SARS-CoV-2 in ambulances

In this study, a low-cost Ultraviolet disinfection system is proposed to be used inside ambulances for minimizing the cross-infection of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) during patient transfer. The disinfection system consists of a tower unit that contains the Ultraviolet type C (UVC) light fixture and a control box where the power unit is placed. The UVC tower unit is portable, lightweight, and can be easily placed anywhere inside an ambulance. Two ultraviolet (UV) lamps used in the tower part have 254 nm wavelength with a total power of 180 Watt. The disinfection system can provide a dose of 16.9mj/cm 2 within 1.06 seconds and 26.83 seconds if the distance of the targeted surface inside the ambulance from UV sources are 0.3 meters and 1.5 meters respectively. We have chosen various distances from UV source to targeted surface inside an ambulance and calculated the required corresponding times to reach the required dose to inactivate all viral concentrations. The designed disinfection system not only reduces the spread of SARS-CoV-2 by the semi-autonomous way inside ambulances but also requires the least labor efforts which are crucial in the current Covid-19 pandemic.

Design of a low cost Ultraviolet Disinfection unit to minimize the cross-contamination of COVID-19 in transport

In this work, a cost-effective disinfection system for Coronavirus Disease of 2019 (COVID-19) is proposed to be used inside public transport. The disinfection system is twofold, firstly containing a tower unit where UV-C (Ultraviolet type-C) lamps are positioned in parallel, in such a way that, 360-degree space is covered, and secondly a power unit that incorporates robotics and electrical parts. The UVC unit is a separate and movable tower that can be placed anywhere inside a vehicle horizontally or vertically. UV lamps in the tower have a 254 nm wavelength with a total power of 180 Watt. The system can provide a dose of 16.9mj/cm2 within 26.83 seconds if the distance of the targeted surface inside a vehicle from the UVC light source is 1.5 meters. Various distances from the UV source to the targeted surface inside the vehicle are chosen and calculated the required corresponding times to achieve the required dose to inactivate all viral concentrations. The developed disinfection system not only minimizes the growth of severe acute respiratory syndrome coronavirus 2 (SARS−CoV−2 ) by performing robotic features ensuring human detection auto turn off but also utilizes minimum labor work which is vital in the current Covid-19 pandemic.
