Noise-Reducing Surgical Aspirator Tip

Inventors at the University of Missouri (MU) have developed a surgical aspirator tip that produces less noise than current products on the market, while maintaining flow rates and minimizing unwanted clogging.

Noise pollution is a well-known problem in hospitals and operating rooms, affecting the quality of care for patients and the work environment for providers. Noise levels in these environments have been found to be consistently above the limits established by federal regulatory agencies, sometimes by as much as 40 decibels.

Surgical aspirators are a commonly used tool that contributes to this occupational hazard. Surgical aspirators currently on the market have been shown to cause sustained noise levels above 70 decibels, with some reaching as high as 120 decibels. This excessive noise pollution can have negative effects, including hearing loss (which has been shown with sustained exposure to sounds above 70 decibels).

MU’s novel surgical aspirator tip design can reduce noise in the operating room while maintaining an effective flow rate and function.
