Abstract: A free radical solution producing apparatus, which comprises: a feed port (6) in which water is drawn, a dechlorination processing section (1) which produces first water by decomposing chlorine compounds in said water, a magnetic processing section (2) which produces second water by carrying out a process that applies a magnetic field to said first water, a radiation processing section (3) which produces third water by carrying out a process that irradiates a radiation to said second water, an ion exchange section (4) which produces fourth water by carrying out a process that performs an ion exchange for said third water, an electric field applying section (5) which produces fifth water by carrying out a process that applies a strong electric field to said fourth water, and a fifth water intake (7-5) from which said fifth water is obtained, produces water which has the effects of sterilizing and disinfection, and strong cleansing power.

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.
