Description
Technical Field
The invention relates to the technical field of medical isolation wards, in particular to a negative pressure isolation ward.
Background
Isolation ward is an isolation treatment measure used for patients during the occurrence of infectious disease epidemic, thereby preventing cross infection of viruses. Existing isolation wards typically deliver purified air to the ward only, but patients continue to produce pathogens that carriers are able to spread, primarily by direct/aerosol and direct contact. For direct/aerosol transmission, the bacteria-bearing gas exhaled by the virus carrier is free in the air, and the people around the virus carrier inhale the aerosol formed by the smell of the infected person who coughs, sneezes and speaks in an unprotected state. For contact transmission, droplets deposit on the surface of the object and contact the mouth, nose or eyes of the person inadvertently contacting the object. The most dangerous of these approaches is aerosol, i.e., bacteria-containing air, resulting in passive infection.
According to the transmission characteristics of viruses, the existing isolation rooms cannot ensure the virus-free state in the ward. Moreover, air in the ward is directly discharged through the exhaust pipe, which causes pollution to air outside the ward.
Disclosure of Invention
The invention aims to provide a negative pressure isolation ward, which can discharge viruses in the ward in time, maintain a virus-free state and avoid discharging polluted air to the outside of the ward.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the negative pressure isolation ward comprises a ward unit, wherein a partition is arranged in the ward unit to divide the ward unit into a ward area and a sterilizing area, and an ozone and ultraviolet sterilizing system is arranged in the sterilizing area; the ward area is provided with an air inlet and an air outlet on the partition; an air inlet purification system and an air exhaust disinfection system are arranged outside the ward unit; the air inlet and air purification system is connected to the air inlet, and the air exhaust and air disinfection system is communicated with the sterilization area; the air exhaust flow of the air exhaust disinfection system is greater than the air inlet flow of the air inlet purification system, so that air flow from the air inlet to the air outlet is formed in the ward area.
Furthermore, an air filter is arranged between the air inlet and the air inlet air purification system.
Furthermore, the air outlet is also provided with an air filter.
Furthermore, the air inlet air purification system sequentially comprises a mixing section, a primary effect section, a fan section, an even section, a middle effect section, a surface cooling section, an electric heating section, a humidifying section, a sterilizing section and an air outlet section along the air inlet direction
Furthermore, a sickbed is arranged in the ward area along the airflow direction.
The invention has the beneficial effects that:
firstly, an air inlet purification system and an air exhaust disinfection system are adopted to generate negative pressure in a ward and form airflow from an air inlet to an air outlet, so that viruses in the ward are timely exhausted along with the airflow, and a virus-free state is maintained.
And secondly, the ward unit is divided into a ward area and a sterilizing area, air is sterilized by ozone and ultraviolet rays in the sterilizing area, and then is sterilized and filtered effectively before being discharged through the secondary sterilization of the exhaust air sterilizing system, so that secondary pollution to the environment is avoided.
And thirdly, air filters are respectively arranged at the air inlet and the air outlet, so that the air filtering effect is enhanced.
Drawings
The invention is further illustrated with reference to the following figures and examples:
FIG. 1 is a schematic structural view of the present invention;
figure 2 is a top view of the patient room unit of the present invention.
Detailed Description
Referring to fig. 1 and 2, the present invention provides a negative pressure isolation ward, which comprises a ward unit 1, wherein a partition 2 is arranged in the ward unit 1, so that the ward unit 1 is divided into a ward area 3 and a sterilizing area 4, an ozone and ultraviolet sterilization system 5 is arranged in the sterilizing area 4, and the ozone and ultraviolet sterilization system can adopt the existing equipment which is commonly used at present; the ward area 3 is provided with an air inlet 6, and the partition 2 is provided with an air outlet 7; an air inlet purification system 8 and an air exhaust disinfection system 9 are arranged outside the ward unit; the intake air purification system 8 is connected to the intake 6 through an intake pipe 10, and preferably, the intake 6 is further provided with an intake air filter 11. The air exhaust and disinfection system 9 is communicated with the sterilization area 4 through an air exhaust pipe 12; the exhaust flow of the exhaust air sterilizing system 9 is larger than the intake flow of the intake air purifying system 8, so that the ward area 3 forms airflow from the intake to the exhaust.
Preferably, the exhaust outlet 7 is provided with an exhaust air filter 13.
The air intake purification system 8 comprises a mixing section 8a, a primary effect section 8b, a fan section 8c, an even section 8d, a middle effect section 8e, a surface cooling section 8f, an electric heating section 8g, a humidifying section 8h, a disinfecting section 8i and an air outlet section 8j which accord with the national purification standard in sequence along the air intake direction.
A patient bed 14 is arranged in the ward area 3 in the direction of the airflow.
The air inlet air purification system and the air exhaust air disinfection system are adopted to generate negative pressure in the ward and form airflow from the air inlet to the air outlet, so that viruses in the ward are timely exhausted along with the airflow, and the virus-free state is maintained.
Because the sickbed 14 is arranged along the airflow direction, medical staff working in a ward are always in the air inlet, and can not breathe polluted air even if the sickbed is not protected by a mask; the patients in the treatment period are always in a clean environment, so that the repeated infection can not be caused.
The ward unit is divided into a ward area and a sterilizing area, air is sterilized by ozone and ultraviolet rays in the sterilizing area, and then is sterilized and filtered effectively before being discharged through the secondary sterilization of the exhaust air sterilizing system, so that secondary pollution to the environment is avoided.
Air filters are respectively arranged at the air inlet and the air outlet, so that the air filtering effect can be enhanced.
The foregoing is merely a preferred embodiment of the invention and is not intended to limit the invention in any manner; those skilled in the art can make numerous possible variations and modifications to the present teachings, or modify equivalent embodiments to equivalent variations, without departing from the scope of the present teachings, using the methods and techniques disclosed above. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention.
