Dynamic isolation type infectious disease isolation ward

Abstract

The invention relates to a dynamic separated contagion room, which is formed by patient room, buffer room, and toilet, with sealing space, wherein it has 60-80n / h exhaust times, 6-8m3 buffer room, and common door; the top plate over the operation position is arranged with main flow area wind let; the inner side of bed head is arranged with reflux open of non-leakage high-efficiency filter; the top plate of buffer room is arranged with wind inlet; the lower part of wall plate is arranged with reflux inlet; and the whole space is arranged with external feeding and exhausting wind tube. The invention has the advantages that: it uses dynamic separate technique, without expensive sealing door and high-passive pressure separation. And it uses non-leakage high-efficiency filter to reflux wind without air conditioner.

Description

technical field [0001] The invention belongs to a special-purpose medical building, in particular to a dynamic isolation type infectious disease isolation ward. Background technique [0002] Patients with respiratory infectious diseases need to be treated in isolation wards, which are composed of patient rooms, buffer rooms, and toilets. Whether it is an isolation ward area built during the epidemic of infectious diseases, or some rooms in an existing hospital are converted into isolation wards, all use Negative pressure isolation technology maintains a certain negative pressure value between the interior and exterior of the ward, so as to prevent the polluted air in the ward from leaking to the outside. [0003] The current negative pressure isolation technology needs to make the exhaust air volume greater than the air intake volume, so that the external negative pressure value of the ward is above -15Pa (as stipulated in Australia's "Classification and Design Guidelines fo...

AI Technical Summary

Problems solved by technology

[0003] The current negative pressure isolation technology needs to make the exhaust air volume greater than the air intake volume, so that the external negative pressure value of the ward is above -15Pa (as stipulated in Australia's "Classification and Design Guidelines for Isolation Wards of Health and Medical Facilities"), resulting in high negative pressure. To prevent the backflow of air, double-sealed doors are used for interlocking, and a single-sealed door costs tens of thousands of yuan (such as the ward built in Hong Kong during the SARS epidemic). Return air, emphasizing the use of fresh air air conditioning, which brings the complexity of the ventilation and air conditioning system, energy consumption, and affects its extended application

[0004] The outstanding problem of negative pressure isolation technology is that the entire isolation ward is in a state of high negative pressure, which only manifests when the door is closed statically, which is essentially static isolation.

When the door is opened and closed, people enter and exit, and the temperature difference between the inside and outside of the air is convected, not only the pressure difference disappears immediately, but the high negative pressure is difficult to maintain, and the internal and external exchange of polluted gases is serious.
