Researchers from the University of Southampton have demonstrated how a pioneering ultrasonic device can significantly improve the cleaning of medical instruments and reduce contamination and risk of infection.
The device supplies a gentle stream of water through a nozzle that generates ultrasound and bubbles, which dramatically improve the cleaning power of water reducing the need for additives and heating.
Using just cold water, StarStream was able to remove biological contamination, including brain tissue from surgical steel.
Principal Investigator Professor Tim Leighton, from the University’s Institute of Sound and Vibration Research, said: “In the absence of sufficient cleaning of medical instruments, contamination and infection can result in serious consequences for the health sector and remains a significant challenge. Our highly-effective cleaning device, achieved with cold water and without the need for chemical additives or the high power consumption associated with conventional strategies, has the potential to meet this challenge and transform the sector.” The research, published in the journal Physical Chemistry Chemical Physics, was funded by the Royal Society Brian Mercer Award for Innovation.
