TECHNICAL FIELD OF THE INVENTION
The present invention relates to an endoscope pipe cleaning device and a pipe cleaning method using a flexible brush filament.
[0002]
[Prior art and its problems]
In the endoscope, a treatment instrument insertion channel, a suction line, and the like are provided. Since various pipelines are contaminated by body fluids or chemicals of the subject, it is necessary to perform brushing washing after using the endoscope to keep them clean. In conventional brushing cleaning, after the cleaning brush is inserted from one end of the conduit to the other end, it is repeatedly pulled out by hand in the direction opposite to the insertion direction many times, so that the inner wall of the conduit is repeated several times. Also rub with a cleaning brush to remove dirt. Recently, in order to reduce the number of times the cleaning brush is inserted, it has been proposed to use a flexible brush linear body 200 as shown in FIG. 7 instead of the conventional cleaning brush. The flexible brush linear body 200 includes a flexible shaft 210 and a plurality of brush portions 220 provided at one end side of the flexible shaft 210 at intervals (see Patent Document).
[0003]
However, the flexible brush linear body 200 must be longer than the entire length of the conduit, and generally has a length dimension of 1 m or more, so it is difficult to manually pull out the flexible brush linear body 200. The brushing cleaning took time and effort.
