What are the main layout modes of laminar flow operating room purification
1. Double corridor type (dirt type)
Double corridor type is the common layout of operating room purification. Starting from "avoiding cross infection", we should pay attention to the disposal of devices and articles after operation, and pay attention to disinfection. The devices and wastes after operation are sent out by the outer aisle, while the other devices, doctors and patients are all sent in and out by the inner aisle.
2. Double corridor type (clean type)
The cleaning layout of the operating room is similar to that of the double corridor type (dirt type). Only the doctors and devices in the operating room before operation are clean and enter from the clean corridor. After the operation, the doctor went out of the clean corridor.
3. Single corridor type
Starting from the concept of "dirt is not dispersed", it is necessary to pack and transport the devices and wastes after operation. Articles requiring disinfection are transported or returned to the operating room after in-situ disinfection. It is necessary to bring the anterior room to the operating room in this way. Its function is to disinfect the surgical articles effectively and completely before and after the operation.
4. Central Island Type
Based on the concept that surgical infection is mainly "touch infection". The aseptic materials transported by the elevator are sent to the operating rooms through the central clean room. After use, the articles are transported out of the outer corridor, and the hand-washing pool used by doctors and nurses should also be set in the outer corridor.
5. Unidirectional flow pattern
Operating room cleaning strictly abides by the cleanliness and sewage diversion criteria. Patients, doctors and sterile articles are unidirectional flow, and reverse flow is not allowed. There is no overlap between the two, which is a complete layout plan to solve the problem of cleanliness and sewage diversion. However, with the increase of the number of operating rooms, the plane flow direction and design will become quite disorderly.
