I. Project Overview

The clean operating department is located on the seventh floor of the outpatient complex building, with a total of 18 operating rooms. The building area of the operating floor is 3489m². It is currently under construction.

II. Floor Plan Layout

The floor plan type of the clean operating department belongs to the peripheral recovery type. The design concept of this plan type proceeds from the perspective of infection prevention, with the handling of post-operative contaminated items being of the utmost importance. The design features of this floor plan are:

(1) Before and after operations, medical staff, patients, sterile instruments, and corresponding auxiliary supplies enter and exit through the central clean corridor, while post-operative waste is promptly removed via the peripheral corridor, thereby achieving the separation of clean and dirty flows.

(2) The building has a triangular layout, with operating rooms arranged on the upper, left, and right sides of the building, and the waste corridor arranged along the exterior walls. Clean corridors and auxiliary rooms are arranged around the central atrium, with the clean corridors extending from the center to each surgical area. The operating department is large in scale, with complete functional rooms and a rational flow process.

(3) Regarding the decorative structure of the operating rooms, large arc transitions are used between wall and wall, and between wall and ceiling, eliminating airflow dead zones and facilitating the organization of clean airflow. The wall material is a metal material that does not rust in itself, offering a long service life and good electromagnetic shielding performance.

III. Air-Conditioning and Purification System

(1) There are 4 Class I operating rooms, each equipped with one medical hygienic-type purification air-conditioning unit, with air supplied through a static pressure air supply device.

(2) There are 6 Class II operating rooms, with every 2 rooms sharing one medical hygienic-type purification air-conditioning unit, with air supplied through a static pressure air supply device.

(3) There are 8 Class III operating rooms, with every 2–3 rooms sharing one medical hygienic-type purification air-conditioning unit, with air supplied through a static pressure air supply device.

(4) The clean corridor and clean auxiliary rooms share one medical hygienic-type air-conditioning unit, with air supplied through high-efficiency air supply outlets.

(5) The cleaning corridor and auxiliary rooms use one medical hygienic-type air-conditioning unit.

(6) Three fresh air units are installed to centrally supply fresh air by zone.

IV. Indoor Airflow Organization

Class I–III operating rooms use centralized air supply outlets, with air supplied from above and returned from below.

The clean corridor and clean auxiliary rooms use high-efficiency air supply outlets, with air supplied from above and returned from below.

The cleaning corridor and auxiliary rooms use high-efficiency air supply outlets, with air supplied from above and returned from above.
