ABSTRACT:
The cleaning member for a medical tube is shaped like a spherical body having a porous fibrous structure formed of a large number of superfine fibers aggregated and intertwined three-dimensionally. The spherical body moves along a lumen surface of the medical tube together with a cleaning liquid, with the cleaning member wiping and cleaning the lumen surface of the medical tube.The porous member for cleaning the treatment appliance insertion lumen of the endoscope is formed approximately spherically by molding a large number of superfine fibers. The porous member can be swelled with an aqueous cleaning liquid. When the porous member swells, the outer diameter of the porous member becomes larger than the inner diameter of a treatment appliance insertion lumen of an endoscope to be cleaned. Further because the porous member deforms, the porous member can be inserted into the treatment appliance insertion lumen of the endoscope. Moreover, the aqueous cleaning liquid flowing into the treatment appliance insertion lumen of the endoscope allows the porous member to move in contact with an inner wall of the lumen.
