Description

A medical device cleaning and disinfection device

technical field

The invention relates to the technical field of medical equipment, in particular to a cleaning and disinfection device for medical equipment.

Background technique

Medical equipment is an important part of the pharmaceutical industry. For consumers, the configuration of medical equipment in medical institutions is second only to the standard used by doctors to judge medical institutions. The country has also devoted a lot of effort to the development of the medical device industry, but today, in the field of high-end products in my country's medical device industry, the competitiveness of local enterprises is still vulnerable. The medical device industry is a multidisciplinary, knowledge-intensive and capital-intensive high-tech industry with a high entry barrier. The overall level of medical equipment in Chinese medical institutions is still very low. Among the medical devices and equipment in primary medical and health institutions across the country, about 15% are products around the 1970s, and 60% are products before the mid-1980s. , the process of their replacement is a process of demand release, which will ensure the rapid growth of China's medical device market in the next 10 years or even longer.

Cleaning/disinfection of medical equipment is one of the key means to prevent and control nosocomial infection and ensure the quality of medical care. It can be said that without excellent medical device disinfection technology, there will be no development of modern surgical technology, and the implementation of various invasive diagnosis and treatment technologies cannot be guaranteed.
