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:
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.
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.
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.
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).
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.
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.
