Abstract

This study represents an engineering approach for the development of a cost effective sterilization device called “Photosweep”. It takes the present sterilization condition one step ahead by using heat generated from the solar energy and germicidal property of UV ray instead of electricity. Photosweep is a dual chamber machine where the first chamber uses the heat from sun, to turn water into high temperature and pressure steam for sterilization of glassware and metallic tools and accessories. In the second chamber, UV ray is extracted from the sun to sterilize plastics (ventilation tube, bio-bags, media solution, etc.) that would usually melt at high pressure and temperature steam. The developed low cost dual function Photosweep can reduce the operation cost for sterilization in small to medium capacity hospitals in low to middle income countries. Further improvement to this technology may augment potential benefits in all level hospitals of various countries having enough day light.
