The present invention relates to a disinfection cloth, and more particularly to a medical endoscope disinfection cloth and an endoscope disinfection cloth sealing system using the same.

Medical endoscopes refer to internal organs or medical devices that allow the inside of the body to be seen directly. Originally designed to insert a machine into an organ that cannot be seen directly without surgery or autopsy. It is an appliance. Commonly used types include bronchoscope, esophagus, gastroscope, duodenum, rectum, cystoscope, laparoscopic, and other special ones such as thoracoscopic, mediastinal and cardiac.

In the endoscope, it is called a straight tube, which allows you to see the organs directly with the naked eye, the type using a lens system, the type that inserts the camera directly into the organ, and the fiber scope using glass fiber. Etc. Recently, a gastric camera and a fiber scope have been widely used for the early detection of gastric cancer. The gastrointestinal camera can detect and diagnose microscopic gastric lesions by inserting a small camera into the stomach and directly photographing and recording the gastric mucosa. In addition, the stomach fiber has a good resolution, and can attach a device capable of cutting and examining lesion tissue while observing mucosal state. In this way, due to the high development of the gastroscope, especially the gastroscope, the endoscope usually refers to the gastric camera and the stomach fiber scope.

When the medical endoscope is inserted into the human body, the body of the endoscope must be disinfected because it is contaminated with various internal substances or germs of the subject during the examination of the stomach or colon.

Conventional endoscope disinfection methods are used by disinfecting the endoscope nozzle at a high temperature of 135 degrees or more, and using a method after washing with a disinfectant (medical alcohol), but sterilization at a high temperature as the number of patients examined increases rapidly. The method of disinfection takes a long time and a problem of shortening the life of an endoscope nozzle, and the method of disinfecting with a disinfectant solution does not completely disinfect, resulting in a secondary infection.

In order to improve this problem, the prior art, as a device for disinfecting the endoscope, proposed a device for disinfecting the endoscope by generating a disinfection sterilization in the "sterilization disinfection cleaning device of the hospital endoscope" of the Republic of Korea Patent Application 10-2001-0017766 , "Endoscopic cleaning disinfection device" of Korean Patent Application 10-2007-7020916 proposed a device for automatically sterilizing the endoscope.
