ultrasonic cleaner
A cleaning device that uses high-frequency sound waves to create cavitation bubbles for removing debris from surgical instrument surfaces.
Full Definition
An ultrasonic cleaner is a specialized cleaning device that generates high-frequency sound waves (typically 25-80 kHz) in a liquid medium to create microscopic cavitation bubbles. When these bubbles collapse, they produce intense localized cleaning action that removes organic and inorganic debris from instrument surfaces, including hard-to-reach crevices and joints. Ultrasonic cleaning is particularly effective for complex instruments with lumens, serrations, or hinged mechanisms. The process requires appropriate cleaning solutions, proper instrument positioning, and validated time and temperature parameters. Regular monitoring of ultrasonic activity and solution quality is essential for consistent cleaning effectiveness.
Usage
Usage note: Never abbreviated as 'US cleaner' to avoid confusion with United States; sometimes called 'sonicator' in laboratory contexts.
