UV disinfection device for catheter sterilization

Project Details

Description

Ultraviolet light kills bacteria by modifying the bacterial DNA such that the bacteria looses their viability. UVC technology (light at wavelengths ~ 265 nm) has been used for decades for drinking and waste water sterilization. The germicidal properties of UVC light are therefore well documented. The invention described here is a medical device based on newly developed UVC light emitting diodes (LED), which can be used for intra-luminaal sterilizing of indwelling intravenous catheters. The UVC LED is placed inside the housing. Relatively small doses of UV light are required to obtain almost 100% killing even in biofilm. Most of the compounds that are part of the biofilm are reasonable transparent for the UV light. The UV light therefore penetrates the biofilm and kills the bacterial cells present inside the protective biofilm layer.
