DESCRIPTION HUS01000

DETACHABLE MOBILE NEGATIVE PRESSURE ISOLATION WARD TECHNICAL FIELD

[01] The present disclosure relates to the technical field of medical equipment, specifically to a detachable mobile negative pressure isolation ward.

BACKGROUND

[02] The role of a negative pressure isolation ward is to isolate, treat, and observe infected or contaminated persons during outbreak of an epidemic or biochemical warfare. The purpose is to avoid large-scale spread, protect medical staff and prevent environmental pollution. Studies have found that the following prevention and treatment measures are mainly taken for current isolated prevention and treatment during the outbreaks of major infectious diseases or biochemical warfare at home and abroad: I, prevention and treatment are carried out through special negative pressure wards. However, some hospitals are only equipped with a few of negative pressure wards and cannot cope with large-scale outbreaks of the epidemic, and these negative pressure wards have been vacant for a long time or have a low utilization rate, leading to waste of resources; II, existing ordinary wards are renovated or isolation wards are specially built, but transformation and building need spend a lot of time and money, resulting in that the epidemic cannot be coped in time and effectively, and the cost is extremely high. In addition, for the outbreaks of major infectious diseases or the biochemical warfare, there is no special isolation ward in China to protect medical staff from being infected and prevent environmental air pollution to the maximum extent when infectious victims (wounded personnel) are treated in isolation.

SUMMARY

[03] In order to overcome the above defects, the present disclosure provides a detachable mobile negative pressure isolation ward. The ward is divided into two areas. One area is used as a ward area (treatment area) used for treating and isolating an infectious victim, and the other area is used as a buffer area used for temporary work, HUS01000 rest, and isolation of related medical staff. It protects the medical staff from being infected and prevents environmental air pollution while effectively coping with the epidemic.

[04] The present disclosure is realized by the following technical solution:

[05] A detachable mobile negative pressure isolation ward includes a cabin body and further includes a negative pressure forming module; the cabin body is divided into a treatment area and a buffer area by an isolation wall; the treatment area and the buffer area are respectively provided with an air inlet and an air outlet; the negative pressure forming module respectively feeds filtered fresh air to the treatment area and the buffer area through the air inlet, and air of the treatment area and the buffer area is discharged through the air outlet; the negative pressure forming module keeps an air discharge volume of the treatment area greater than an air supply volume so as to form a negative pressure environment in the treatment area and keeps the air supply volume of the buffer area greater than the air discharge volume so as to form a positive pressure environment in the buffer area, thereby ensuring that the air flows from the buffer area to the treatment area and finally to the outside of the cabin body.

[06] A working principle of the present disclosure is: by means of the arrangement of the negative pressure forming module, the treatment area keeps a negative pressure environment, and the buffer area keeps a positive pressure environment, so as to ensure an ordered flowing manner of air from the buffer area to the treatment area to the outside of the cabin body. On the one hand, polluted toxic air carrying pathogenic bacteria in the treatment area flows back into the buffer area to infect medical staff, and on the other hand, polluted air is discharged into the atmosphere outside the cabin body after being intensively disinfected and filtered, so as to prevent environmental pollution.

[07] Further, the negative pressure forming module of the present disclosure includes an air intake system and an air exhaust system; the air intake system includes a first air filter, an air conditioner, a first air blower, and an air intake pipe; fresh air enters the air conditioner for temperature and humidity regulation after being filtered by the first air filter, and is then conveyed by the air blower to the buffer area and the treatment area through the air inlet of the air intake pipe; the air exhaust system includes a second air HUS01000 filter, a disinfection device, a second air blower, and an air exhaust pipe; and after being disinfected and filtered via the disinfection device and the second air filter, polluted air of the buffer area and the treatment area discharged via the air outlet is pumped out by the second air blower and discharged into the atmosphere. Both the fresh air and exhaust air of the present disclosure pass through air supply outlets and air discharge outlets which are independently formed in the buffer area and the treatment area; pressures of spatial areas (the buffer area is at a positive pressure and the treatment area is at a negative pressure) are formed through a relative relationship of an air supply volume and an air discharge volume, so that the air orderly flows from the buffer area to the treatment area, which effectively avoids the polluted air from entering the buffer area to infect medical staff, and the polluted air is disinfected and filtered before being discharged to the outside of the cabin body, so as to prevent the environmental pollution.

[08] Further, the disinfection device of the present disclosure adopts, but is not limited to, an ultraviolet or plasma sterilizer.

[09] Further, the negative pressure of the treatment area of the present disclosure is preferably -5 to -15 Pa.

[10] Further, an entrance of the cabin body of the present disclosure is an automatic induction door; an inner wall of the cabin body is lined with a heat insulation, sound insulation fireproof material; the isolation wall is provided with an automatic induction isolation door and is further provided with a transfer window. By the arrangement of the automatic induction isolation door and the transfer window, the present disclosure can effectively reduce contact infections to the medical staff and further improves the safety of the medical staff.
