Firstly, the negative pressure isolation ward is an important medical facility for treating respiratory tract infectious patients with strong infectivity, isolating pathogenic microorganisms and protecting medical staff. For the building and equipment design of negative pressure ward, the decoration construction of negative pressure ward shall be analyzed in detail:

对于负压病房装修的要求：密闭、舒适、洁净，具备ICU病房的抢救功能，病房的隔离方式分为流程隔离和空气隔离，有相当的特殊性，流程隔离是通过建筑平面，严格遵守相关流程，防止病菌外泄。而空气隔离是通过洁净技术的运用，在各区域形成气压差，防止病菌向外扩散，因此设计施工难度大，造价昂贵，运行、维护费用较高。

Requirements for the decoration of negative pressure Ward: closed, comfortable and clean, with the rescue function of ICU ward. The isolation mode of ward is divided into process isolation and air isolation, which has considerable particularity. Process isolation is through the building plane and strictly abide by relevant processes to prevent the leakage of bacteria. The air isolation is to form the air pressure difference in each area through the application of clean technology to prevent the outward diffusion of bacteria. Therefore, the design and construction is difficult, the cost is expensive, and the operation and maintenance cost is high.

负压病房设计</a>主要包括：院内的选择位置、功能分区、负压病房空调设计、配套设施的设计。

Negative pressure ward design < / a > mainly includes: selection of location in the hospital, functional zoning, air conditioning design of negative pressure ward and design of supporting facilities.

负压病房装修在位置选择上注重的是人流量，设置在医院人流较少的地方，远离居民住宅，或安排在建筑物的层，或布置在病区的尽端，有独立的医护人员和病人入口和通道，若在顶层应有独立的电梯，要有足够的独立设置。

The decoration of negative pressure ward focuses on the flow of people in the location selection. It is set in the place with less flow of people in the hospital, away from residential buildings, or arranged on the highest floor of the building, or at the end of the ward. There are independent entrances and passages for medical staff and patients. If there is an independent elevator on the top floor, there should be enough independent settings.

负压病房有严格的功能分区，按功能要求设置四个区域：工作人员生活区（清洁区）、工作区（半污染区）、病房区（污染区）、设备区（空调排风机房）。

The negative pressure ward has strict functional zoning, and four areas are set according to functional requirements: staff living area (cleaning area), working area (semi polluted area), ward area (polluted area) and equipment area (air conditioning exhaust fan room).

各区既独立又相连接，连接处设缓冲区，并由隔离门进行隔离，细分分区其工作人员生活区会设置工作人员休息室、值班室和卫生间；工作区设置护士站、治疗室、医生办公室、更衣室、卫生通过室、缓冲室、库房、污洗室和工作人员卫生间；病房（污染区），病室按单间设置，有独立的卫生间，病区设病人通道兼作病人活动；机房区，负压病房既须洁净又要求负压，设备较多，应配置足够的空调和排风机房。

Each zone is independent and connected. A buffer zone is set at the connection and isolated by the isolation door. The staff living area will be provided with staff rest room, duty room and toilet; The working area is equipped with nurse station, treatment room, doctor's office, dressing room, sanitary passage room, buffer room, warehouse, sewage washing room and staff toilet; Ward (polluted area), the ward is set as a single room, with an independent toilet, and the ward is equipped with a patient channel for patient activities; In the machine room area, the negative pressure ward shall be clean and require negative pressure. There are many equipment, and sufficient air conditioning and exhaust fan rooms shall be configured.

空调设计是整个负压病房装修的，它决定着负压病房的环境质量，通过设置办公正压区域，对病房负压区域形成一种包围，能有效阻止污染空气向外传播。空气隔离更重要的是压差控制，通过合理的平面设计，在相邻的不同房间建立压差，能有效阻止气体从污染区流向半污染区。

Air conditioning design is the focus of the decoration of the whole negative pressure ward, which determines the environmental quality of the negative pressure ward. By setting the office positive pressure area, a kind of surrounding is formed for the negative pressure area of the ward, which can effectively prevent the spread of polluted air. The most important thing of air isolation is differential pressure control. Through reasonable plane design, differential pressure is established in different adjacent rooms, which can effectively prevent gas from flowing from the polluted area to the semi polluted area.
