Description

Air safety room system for negative and positive pressure {AIR SAFE ROOM SYSTEM FOR NEGATIVE PRESSURE ROOM AND POSITIVE PRESSURE ROOM}

The present invention relates to an air safety room system, and more particularly, to a tent-type indoor space in a hospital or house that requires a clean room. It relates to an air safety room system for negative and positive pressure.

In general, a negative pressure isolation ward is intended to accommodate and treat patients separately from the outside and general patients for reasons such as preventing the spread of infectious diseases, and is included in the air or aerosol or droplets in the ward by maintaining the air pressure in the ward lower than atmospheric pressure. It refers to a facility that prevents pathogens from being discharged to the outside.

In general, the basic structure of a negative pressure isolation hospital room is arranged in order so that the absolute value of negative pressure increases in the order of the hallway, the front room, the hospital room, and the bathroom. An air supply unit is located in an area adjacent to , and a differential pressure gauge for checking air pressure is installed in the front chamber.

However, since the conventional negative pressure isolation ward is built to be fixed in an indoor space such as a hospital, there is a serious problem in that enormous cost and time are required for its installation, and it is difficult to respond quickly to it when a new infectious disease spreads.

An alternative to the negative pressure ward, which requires a lot of installation cost, is to install a negative pressure tent and install it when necessary. The conventional negative pressure tent takes a long time to install and the manufacturing cost required to manufacture the negative pressure tent is high. There was a problem that could only increase the price of the tent.

In addition, since the conventional negative pressure tent can be used only with a structure that maintains the space inside the tent at a negative pressure, the installed negative pressure tent cannot be used for purposes other than maintaining a negative pressure, so when it is necessary to maintain a positive pressure for space use, the negative pressure tent is not used at all. There was a problem that space utilization and usability of negative pressure tents were poor because they could not be used.
