Abstract
A cleaning tool is disclosed for cleaning hard-to-reach and sharply curved passages, particularly those of endoscopes. The tool includes a brush connected to a spring. The spring is connected to a length of flexible tubing. A stiffening member is disposed within the flexible tubing. A fluid passage is provided within the tubing for delivering cleaning fluid or rinsing fluid to the interior of the object being cleaned.

A tool for cleaning endoscopes or the like comprising:
- an elongated flexible plastic tube having a fluid inlet opening adjacent a proximal end and an outlet opening adjacent a distal end;
- a stainless steel coil spring connected to and extending from a distal end of the tube;
- a cleaning member having a stem connected to a distal end of the spring;
- and
- a stiffening member disposed within the tube and extending substantially the length thereof, the stiffening member being sized smaller in cross section than the interior of the tube to provide a fluid passage between the stiffening member and the tube;
- whereby fluid entering adjacent the proximal end and exiting adjacent the distal end of the tube enters the interior of the coil spring and exits the coil spring adjacent the cleaning member through spaces between the spring coils.
