摘要：Biofilm/debris is removed from interior and exterior surfaces of small boretubing by passing an aqueous cleaning solution of water, one or more surfactants andpreferably a hydrogen peroxide source, optionally including small inert solid particles,together with a gas under pressure, to create a turbulent flow within the tubing whichloosens the biofilm/debris so it can be flushed from the tubing. When the exterior tubingsurfaces are cleaned, the tubing is inserted in a sleeve fitted with an adaptor providing apressure-tight seal between the tubing and the sleeve. The figure schematically shows anapparatus for cleaning interior and exterior walls of endoscopy tubing: Compressor (100)carries air in line (102) through pulsation control nozzle (104) to mixing chamber (106); airflow is controlled by pressure regulator (108). Chamber (110) stores cleaning solution,passing it through line (112) to mixing chamber (106), and the resultant turbulent mixturepasses through line (114) to adaptor (116) providing a pressure-tight fitting to a port oftubing (120), while line (115) carries cleaning solution to the exterior tubing surfaces.
