CCN integrated modularized negative pressure isolation ward

Abstract

The invention discloses a CCN integrated modularized negative pressure isolation ward. The CCN integrated modularized negative pressure isolation ward comprises a first changing isolation room, a second changing isolation room, a ward area, a treatment area, a warehouse and a second isolation buffer room, wherein the ward area comprises a patient passage and a plurality of wards, a first isolationbuffer room is formed between the first changing isolation room and the patient passage, the treatment area comprises a treatment room system and a treatment area passage, and the second changing isolation room communicates with the treatment area passage; the treatment room system comprises a nurse station room, a treatment room and a doctor office room, and the treatment area passage communicates with the warehouse and the second isolation buffer room separately; and the first isolation buffer room is a shower room or an air shower room, and the second isolation buffer room is a shower roomor an air shower room. According to the CCN integrated modularized negative pressure isolation ward, the negative pressure isolation ward is established in a modularized manner, and viruses can be effectively prevented from spreading in the isolation ward and spreading to the outside, so that a remarkable isolation effect is acted, and virus isolation treatment, and epidemic prevention and control are benefited.

Description

technical field [0001] The invention relates to the field of virus isolation, in particular to a CCN integral modular negative pressure isolation ward. Background technique [0002] At present, there is no definite and effective treatment for the new coronavirus. Medical institutions should prioritize isolation as the first measure to avoid the spread of the epidemic. However, effective isolation and protection of personnel must have a standard CCN modular biosafety negative pressure isolation ward to avoid suspension Leakage of infectious agents in the air. Because of this epidemic, the importance of CCN modular biosafety negative pressure isolation wards has been valued by various medical institutions. At present, there are many problems in the construction of domestic isolation wards, and unified and standardized standards are urgently needed as a basis for design, construction, and acceptance. Even if relevant isolation ward design specifications or acceptance specifica...

AI Technical Summary

Problems solved by technology

However, some design units lack the basic knowledge of isolation theory, do not consider partitions (clean area, semi-polluted area, and polluted area) in layout, do not consider unidirectional flow in air flow organization, and have unclear pressure gradients and other issues: 1. Ventilation and air conditioning The content of the construction design drawing is incomplete, lacks the indoor parameter requirements of isolation wards and general wards, lacks necessary section drawings or descriptions, and lacks necessary technical requirements and descriptions for air-conditioning units, high-efficiency filters and other equipment

2. No high-efficiency filter is designed for the return air outlet (section) of the isolation ward, and the exhaust fan of the system has no spare fan

3. The description of exhaust control in the design and construction instructions of the drawings: "The exhaust fan is linked with the purification air conditioning unit. When the purification unit is turned on, the exhaust fan is turned on. When the purification unit is turned off, the exhaust fan is turned off." Operating according to the design method will cause positive pressure in the negative pressure room during the startup and shutdown process, resulting in the leakage of pollutants

4. There is no ventilation and air conditioning facilities in the polluted corridor, which is not conducive to the formation of an orderly pressure gradient

5. There are no ventilation measures in the buffer room of the ward for the treatment of suspected patients, which makes it difficult to form the necessary pressure gradient, which will lead to the spread of pathogenic microorganisms in the building
