Three characteristics of clean room

(a) the clean room is a place for human activities, and the air cleanliness has reached a certain level. Clean the lab. The efficient and safe air purification system in the operating room ensures the aseptic environment of the operating room, which can meet the high aseptic environment required for organ transplantation, heart, blood vessels, artificial joint replacement and other operations. It is a powerful measure to ensure the sterile environment of general operating rooms to adopt efficient and low-toxic disinfectants and use them reasonably. Laboratory purification ensures that the cleanliness of the operating table reaches the standard. Generally, the laminar flow operating room with good vertical laminar flow effect is a "positive pressure" environment, and its air pressure changes according to the cleanliness requirements of different areas (such as operating room, aseptic preparation room, hand brushing room, anesthesia room and surrounding clean areas, etc.). Its function is to control particle pollution. The clean room is not generally clean, but has reached a certain air cleanliness.

(2) The clean room is multifunctional. First of all, we need more professional cooperation of construction, air conditioning, purification, pure water and pure natural gas. As far as pure gas is concerned, the process gas should also be purified. For example, in the disposable syringe factory, the compressed air used in the injection workshop is not particularly purified due to the design process. Every time the product is molded, a large amount of unpurified compressed air will be released, which will make the air cleanliness in the workshop not meet the requirements and cause pollution to the molded products. Therefore, dry air, compressed air and inert gas in direct contact with drugs should be purified to meet the production requirements. Secondly, several parameters need to be controlled, such as air cleanliness, bacterial concentration, air volume (air volume), pressure (air pressure), sound (noise), light (illumination) and so on.

(3) As for the quality of clean room, in terms of importance, design, construction and operation management, that is, the clean room itself reflects its quality in the whole process from design to management. The difference between clean air conditioning and general air conditioning.
