Operating Room Clean Room Design

In surgery, if the environment is not clean enough, the dust brought by the personnel walking, the dust in the air, and the bacteria released during the surgery fall into the incision, which is easy to cause infection, so it needs a clean room. In this article we will introduce the design of clean room in the Operating Room.

Operating Theatres in hospitals are also generally required to meet clean room standards. Depending on the importance of the operation, operating theatres need to be designed with different levels of cleanliness.

Some special aseptic purification operating room, that is, usually said to be the first level of operating room, the need to use local laminar flow of 100 cleanliness of the Clean Room. Aseptic operating theatre, that is, the second level operating theatre, need to use the cleanliness level of 1000-10000 class clean room. General operating theatre or surgical auxiliary area, that is, the third level operating theatre needs to use 100000 level cleanliness of the clean room.

Operating room clean room design should be clean operating room as the core, and then configure some necessary auxiliary rooms. The principle of design is reasonable process, reasonable partition, clean and dirty, reduce contact infection and prevent cross-infection. Operating room clean room is generally divided into clean area and non-clean area. Specialised human circulation channels should be set up, as simple and fast as possible.

Patients need to change special gowns and sick trolleys before entering the clean area of the operating theatre. Doctors and nurses should also do a good job of purification, wear special surgical gowns, masks and gloves, and do a good job of sterilisation, so as not to bring germs to the patients in the course of surgery. Set up an independent logistics channel for the transport of surgical items. Sterile instruments, disposables, sterile dressings, etc. needed for surgery enter the operating theatre through the clean room logistics channel, and some surgical wastes must be sterilised and packaged close to the operating theatre after use and sent out of the operating theatre in a timely manner.

There are various layout methods for the plan design of the clean room of the operating room, which should be flexibly selected according to the specific conditions of the operating room, such as: the operating room with an anteroom, consisting of anaesthesia preparation room, hand brushing room, rinsing and sterilizing room of three anterooms and an operating room area; the single-channel type of the operating room without an anteroom, consisting of the operating room and the side rinsing and sterilizing room, hand brushing room, and the anaesthesia preparation adopts centralized setup; the dual-channel type of the operating room without anterooms, consisting of the operating room, clean corridor, clean corridor, rinsing and disinfection room, hand brushing room can take a collection or decentralised setup, anaesthesia preparation room is set up centrally; no anterior room branch double-channel type (multi-channel) arrangement, this form of arrangement is generally applicable to large-scale surgery.
