<p>In a method and apparatus for cleaning tubular elements such as cannulated medical instruments, cleaning fluid is passed through the element and is pulsed at a frequency in or below the audible range by means of a pump (15). Bubbles of air or another gas may be added to the stream of cleaning fluid to produce a more vigorous cleaning action, the gas being pressurised by a compressor (25) and added to the fluid at a valve (33). Means for dispersing the gas in the fluid, such as an impeller, may also be provided. <IMAGE></p> |
