METHOD FOR CLEANING A LUMEN

摘要

A method and apparatus for removing soil from an inner surface of a lumen wall of a medical instrument are disclosed. A carrier gas entrains particles capable of sublimation at room temperature and transports the particles into and through the lumen. As the particles collide with the soil attached to the inner surface of the lumen wall, and as the particles sublime, the soil is removed from the inner surface of the lumen wall and transported out an exit of the lumen.
