TH20291Y - Closed control room with negative pressure. - Google Patents

Abstract

A negative pressure closed-system room is a sealed room with controlled entry and exit for personnel and infected patients, and a systematically controlled air circulation system. It comprises an ante room, a laboratory, and an evacuation room, each equipped with ventilation systems, air purification equipment, and/or sterilization systems. These functions manage the air within the negative pressure room to ensure clean, cool air, control the airborne spread of infection from infected patients to personnel, and filter or sterilize the air before releasing it into the environment.

Claims (8)

1. A closed-system negative pressure room is provided, consisting of a workroom (10) for the screening of patients and the performance of procedures and treatment of patients. The first part is provided with one entrance/exit door (11) for the entry and exit of infectious patients, to bring patients into and out of the room. Above the entrance/exit door (11), there is a special feature: the outside of the entrance/exit door (11) is equipped with additional ventilation, air purification equipment and/or sterilization systems to filter the outside air before entering the workroom (10). The second part is provided with two entrances (12) for the operators, who may be medical personnel or related persons, to access the ante room (20) for preparation before entering the workroom (10). Infectious patients are brought into the workroom (10) in a sterile zone, which is connected to the entrance/exit door (11) to facilitate the operation. The sterile zone is divided into two parts: the first part is for infectious patients, and the second part is for the operators. It is equipped with an air conditioner (17) working in conjunction with a ventilation system, air purifier and/or sterilization system to eliminate pathogens before sending air from the laboratory (10) to the outside to create a negative pressure room inside the laboratory (10), and provides two exit doors (15) for operators to exit the laboratory (10) to continue to the discharge room (30). The discharge room (30), which is connected to the laboratory (10), is equipped with facilities for cleaning, storage of used or contaminated instruments and materials, to serve as a collection point for disposal outside, where the discharge room (30) is further equipped with a ventilation system, air purifier and/or sterilization system, and on one side there are three exit doors (15) for operators to exit the discharge room (30). 2. A closed, negative pressure control room, as per claim 1, where air purification and/or sterilization equipment can be selected from options including coarse filtration, fine filtration, HEPA filter filtration, blower, air conditioning, UV-C lamps, plasma ionization, or ozone sterilization, either individually or in combination. 3. Closed control room with negative pressure as per claim 1, where two entrance doors (12) upon entering the second section are provided to be fitted with an air purification and/or sterilization system, selectable from coarse dust filtration, fine dust filtration, HEPA filter, blower, air conditioner, UV-C lamp, plasma discharge, or ozone for sterilization, either individually or in combination. 4. A closed, negative pressure control room, as per claim 1, where appropriate two entrance doors (12) are provided, which are double doors provided with two entrance doors (12) additionally fitted with inner doors (13) perpendicular to each other on each level to prevent pathogens and air exchange inside and outside. 5. A closed, negative pressure control room, as per claim 1, in which a suitable laboratory (10) is provided with ventilation, air purification equipment and/or sterilization systems located above the head of the infectious disease patient's bed to dilute and eliminate pathogens present in the laboratory (10) to prevent the spread of disease. 6. A closed, negative pressure control room, as per claim 1, in which the laboratory (10) is provided with additional patient beds, medical amenities, patient toilets, and patient relaxation aids which can be selected from a display screen, tablet, television, music player, or lighting system, either individually or in combination. 7. A closed, negative pressure control room, as per claim 1, which shall be provided with two suitable exit doors (15) located opposite the inner entrance door (13) in the operator's path to the exit preparation room (30). 8. A closed, negative pressure control room, as per claim 1, where the three exit doors (15) are provided on the exterior of the three exit doors (15) above, with additional ventilation, air purification and/or sterilization systems to filter the outside air before entering the laboratory (10) in order to sterilize the air inside before it is released into the external environment.
