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.

Abstract: A cleaning apparatus (1) for cleaning the interior surface of a channel of a medical instrument includes an ultrasonic cleaning device having a cleaning catheter (2) provided with ultrasonic vibrators (4, 5) for separating undesired matter from the interior surface of the channel (12) of the medical instrument by ultrasonic vibration; and an ultrasonic oscillator (8) for operating the ultrasonic vibrators (4, 5). The cleaning apparatus (1) further includes a cleaning liquid discharge device (13) having a cleaning liquid feeding tube (10) into which the cleaning catheter can be inserted with the ultrasonic vibrators (4, 5) exposed and which expels a cleaning liquid from a front end thereof; a cleaning liquid storing tank (14); and a pump (16) for feeding the cleaning liquid.
