Abstract

According to the present invention, a pre-cleaning process is performed for removing a physical substance such as blood, mucus or tiny pieces of tissue that are attached to the exterior of the medical device and are inside a duct or a hollow portion. Then, the pre-cleaned medical device is immersed in a chlorine dioxide solution and / or a chlorine dioxide solution is passed through the duct or the hollow portion. Thereafter, the medical device is placed in a chlorine dioxide gas atmosphere and / or a chlorine dioxide gas is passed through the duct or the hollow portion. In this manner, the exterior of the medical device and the interiors of the duct and the hollow portion are deodorized, disinfected and sterilized.

Description

technical field [0001] The invention relates to a method for cleaning and sterilizing medical appliances after use. The object dealt with by the present invention belongs to gastroscope and other endoscopes such as fiberscope, laparoscope, thoracoscope, arthroscope, etc., as well as other long-dimensions such as catheters, hoses, etc., which are hollow inside and are repeatedly used for insertion into the body. pipeline. Background technique [0002] In order to avoid accidents such as nosocomial infection caused by bacteria and viruses, cheap medical equipment such as syringes, injection needles, and IV sets are not reused for economic reasons, which are so-called disposable consumables. However, gastroscopes and other endoscopes such as fiberscopes, laparoscopes, thoracoscopes, arthroscopes, and other high-priced medical devices such as catheters and hoses need to be reused in principle. After use, such medical instruments need to be cleaned, sterilized, deodorized, and ...
