How to Do Disinfection and Protection of Tuberculosis Wards? the Point is Here!

At present, tuberculosis (TB) is still the most important fatal infectious disease in the world. With the continuous improvement of disease prevention and management measures, the World Health Organization (WHO) estimates that from 2000 to 2017, nearly 54 million tuberculosis-related diseases have been avoided worldwide. Death, despite this, nearly 10 million people still suffer from tuberculosis each year, making the goal of “stop tuberculosis” still out of reach.
Ending the global tuberculosis epidemic is one of the 2015-2030 Global Sustainable Development Goals (SDGs). In 2014, the World Health Assembly passed the “WHO End TB Strategy” (WHO End TB Strategy), which emphasizes Various strategies for tuberculosis prevention include infection prevention and control (IPC) in medical and health institutions and other places with a high risk of transmission of Mycobacterium tuberculosis. The implementation of the IPC strategy mainly reduces the risk of transmission of Mycobacterium tuberculosis by reducing infectious droplet nuclei in the air and reducing the exposure of susceptible people to infectious aerosols.
In hospitals, medical staff has close contact with tuberculosis patients to perform tracheal intubation or endotracheal aspiration, aerosol treatment, etc., which easily produce aerosols, which increases the risk of infection for medical staff. Relevant data show that the infection rate of Mycobacterium tuberculosis among medical staff in my country is 50%-70%, and the average annual prevalence is between 415 per 100,000 and 2240 per 100,000.
Concurrent disinfection and terminal disinfection play a key role in the protection of tuberculosis. The tuberculosis outpatient clinic (2012 edition) clearly states that necessary environmental control measures, such as ventilation and ultraviolet disinfection, should be provided for tuberculosis clinics and wards.
At the 2019 National Infection Control and Drug-Resistant Infection Conference, Director Lu Ye of the Zhejiang Provincial Center for Disease Control and Prevention recommended an upper-level germicidal UV lamp device for daily disinfection of tuberculosis wards.
He pointed out that the real upper layer ultraviolet lamp converts the traditional scattered ultraviolet light into concentrated parallel light, which illuminates the upper part of the room in a directional direction to form an efficient sterilization layer on the upper part of the room.
A flat layer is formed in the upper part of the room, and the natural convection effect of indoor air is used without circulating wind. When the floating and diffused tuberculosis bacteria in the air rise to the ultraviolet flat layer, they will be quickly killed.
Doneax’s upper-level flat-radiation ultraviolet photocatalyst air disinfection machine product uses imported high-energy ozone-free ultraviolet lamps, using optical principles to generate upper-level irradiated ultraviolet rays, and combines ultraviolet LEDs and imported photocatalyst disinfection technology to disinfect the air in the room. Infrared detection is adopted, and the upper-level UV flat radiation is automatically turned off when the height of the personnel exceeds 2.1m, and the coexistence of man and machine is easily realized.
In addition to air, it is also necessary to perform terminal disinfection of the environmental surface of the tuberculosis ward.
The ultraviolet disinfection robot controls the high-pressure inert gas xenon lamp to emit pulsed light and emits high-energy, broad-spectrum pulsed light (up to 20,000 times the sunlight, equivalent to 300 times the energy of the ultraviolet lamp) in a very short time to quickly destroy harmful Viruses, fungi, bacteria, spores, and other microorganisms! Strict tests have proved that pulsed strong light has a good killing effect on large-scale infectious bacteria such as H7N9, SARS, EBOLA, and so on.
