Description

Technical Field

[0001] The present invention relates to the field of medical clinical technology, and more particularly, to a cleaning and sterilization device and method for medical flexible endoscopes. Background Art

[0002] With the improvement of medical technology and the widespread application of advanced endoscope products, various types of medical flexible electronic endoscopes (abbreviation: flexible endoscopes) are often used in hospital clinics for disease examination and surgical treatment. After use, the flexible endoscopes and their accessories need to be promptly and thoroughly cleaned and sterilized before they can be used again.

[0003] Currently, there are mainly two types of methods for cleaning and disinfecting used medical flexible endoscopes in medical clinics: one is to clean and soak disinfect by manual means in a dedicated flexible endoscope cleaning tank, that is: place various used flexible endoscopes in a dedicated enzyme solution pool and a clear water pool, manually clean the outer surface of the flexible endoscope body, and use a slender soft brush to clean the inner pipeline of the flexible endoscope; after cleaning, the flexible endoscope is placed in a disinfectant pool for soaking disinfection; then, the residual disinfectant on the outer surface of the flexible endoscope is rinsed with sterile water, and the inner and outer surfaces of the flexible endoscope are dried with sterile air. The dried flexible endoscope is placed in an endoscopic drying storage cabinet for standby; the other is to use a single-tank or double-tank endoscopic cleaning and disinfection machine to replace manual labor to complete the cleaning and disinfection of the flexible endoscope, that is: place the used flexible endoscope coiled in the cleaning tank of the endoscopic cleaning and disinfection machine, and automatically complete the flexible endoscope cleaning and disinfection processes such as spray enzyme washing, clear water rinsing, disinfectant soaking disinfection, clear water rinsing, and sterile air drying according to the standard program of the washing and disinfection machine. A micro water pump is used to circulate and rinse the inner pipeline of the flexible endoscope.

[0004] The above two types of medical flexible endoscope cleaning and disinfection methods have the following problems:

[0005] (1) The operation efficiency of manually cleaning and disinfecting flexible endoscopes is relatively low, and the processing by the endoscopic cleaning and disinfection machine is also time-consuming, which cannot meet the requirements of the hospital endoscopic center for quickly cleaning and thoroughly sterilizing hundreds of used flexible endoscopes every day;

[0006] (2) Whether it is manual cleaning or cleaning by the washing and disinfection machine, there are deficiencies in the cleaning and disinfection of biological films and the like contaminated in the inner pipeline of the flexible endoscope; and when using the washing and disinfection machine, the flexible endoscope is coiled in the cleaning tank, there will be cleaning dead corners, and only by spray rinsing, the removal of contaminants on the mirror body and the inner pipeline is not thorough enough.
