The laminar flow operating room adopts the air cleaning technology to control the microbial pollution in different degrees, so as to meet the requirements of controlling the air cleanliness in the space environment, which is suitable for all kinds of operations, and to provide appropriate temperature and humidity, so as to create a clean and comfortable operating space environment. Because the operating room should strictly control the low number of bacteria and low concentration of anesthetic gas, the stability of laminar flow ultra clean device is an important acceptance index of laminar flow purification operating room. Due to the subtle differences between European and American operating room cleaning standards and China's environment, conventional international standards and domestic regional industry standards are generally difficult to ensure the long-term stability of operating room cleaning (generally only 3-10 years of reconstruction, low-grade projects need to be renovated in one year), so there is an obvious level division in engineering quality. Some well-known purification engineering companies, in addition to the general standards, basically have their own purification indicators that are higher than the international general standards.
