Sterilizing method for medical equipment and its cleaning sterilizer

Abstract

The sterilizing method for medical equipment is to combine the sterilizing function of ozonized water and organic matter degrading function of enzyme. The equipment be used to sterilize endoscope andsurgical instruments, and the sterilizing includes the steps of: washing with enzyme solution, washing with water, sterilizing with high concentration ozonized water, stoving and no-harm treatment. The cleaning sterilizer for implementing the said method includes an enclosed sprayer, an ozone generator, a stove and a microcomputerized control system and includes a no-harm treater.

Description

technical field [0001] The invention relates to the field of disinfection of medical instruments, in particular to a disinfection method for medical instruments such as endoscopes and surgical instruments and a cleaning and disinfecting machine thereof. Background technique [0002] With the advancement and rapid development of science and technology, especially the emergence of fiberoptic endoscopes, the use of endoscopes (also known as endoscopes) and various minimally invasive surgical instruments in the medical field has become more and more extensive and important, and is rapidly Forming a branch of clinical medicine, endoscope-mediated diagnosis and treatment have become very important, even one of the essential means in clinical medicine. Endoscopes and surgical instruments directly enter the human body, and if disinfection is not thorough, it will lead to hospital-acquired infections. Due to the complex structure of the endoscope, especially the structure of the fib...

Problems solved by technology

Endoscopes and surgical instruments directly enter the human body, if disinfection is not thorough, it will lead to iatrogenic infection

Due to the complex structure of the endoscope, especially the structure of the fiber endoscope and the characteristics of the materials used, the light source conduction material (light guide fiber) is glass fiber, which is not resistant to high temperature and high pressure, and is not resistant to radiation. Sterilization is difficult to cut into

Furthermore, endoscopes are expensive (especially imported products), and the number of various endoscopes owned by most hospitals in China is very limited.

[0003] The existing chemical disinfection method (also known as low-temperature disinfection method) cannot achieve short-term disinfection and sterilization without harm, and cannot meet the requirements of people's diagnosis and treatment, and the disinfection process is complicated and takes a long time. Formaldehyde, ethylene oxide, glutaraldehyde They are all toxic substances, and the residual problem is difficult to solve. The operator is very inconvenient and vulnerable to injury during disinfection, and the disinfection effect is greatly affected by human factors. At the same time, it is difficult to make the waste liquid after cleaning and disinfection harmless and cause disease. Microorganisms and harmful compounds are easy to pollute the external environment after discharge, and the problem of pathogenic microorganisms spreading, mutating, and re-spreading infection in the external environment is not easy to solve
