TECHNICAL FIELD OF THE INVENTION
The present invention relates to an endoscope pipeline cleaning device and a pipeline cleaning method using a flexible brush filament.
[0002]
[Prior art and its problems]
Inside the endoscope, pipes such as a treatment tool insertion channel and a suction pipe are provided. The various conduits are contaminated by the subject's body fluids, chemicals, and the like, and therefore need to be cleaned and cleaned after use of the endoscope. In conventional brushing cleaning, after inserting the cleaning brush from one end of the conduit to the other end, the operation of pulling out by hand in the direction opposite to the insertion direction is repeated many times, so that the inner wall of the conduit is repeated several times. They are also rubbed with a cleaning brush to remove dirt. Recently, in order to reduce the number of insertions of the cleaning brush, it has been proposed to use a flexible brush filament 200 as shown in FIG. 5 instead of the conventional cleaning brush. The flexible brush striated body 200 includes a flexible shaft 210 and a plurality of brush portions 220 provided at one end of the flexible shaft 210 at intervals.
[0003]
However, since the flexible brush filament must be longer than the entire length of the pipe, and generally has a length of 1 m or more, it is difficult to pull out the flexible brush filament manually, and brushing is difficult. Cleaning took time and effort. In addition, when the flexible brush striated body is pulled out, the sewage and the chemical solution accumulated in the pipeline may be scattered to the user and the surroundings, which is not preferable in terms of hygiene.
