Globally, 513,955,910 confirmed cases of COVID-19, including 6,249,700 deaths, were reported by the World Health Organization (WHO) as of 5.31 p.m. on 6 May 2022. Data show that Europe has the highest number of confirmed coronavirus cases, followed by the United States. The global epidemic continues to be severe, and China is no exception, especially as the number of coronavirus cases in the international metropolis, led by Shanghai, is increasing, resulting in the Government of Shanghai implementing difficult containment policies to alleviate the current critical situation. At the same time, alarm bells have been sounded for the next outbreaks in other first- and second-tier cities. Not only do basic precautions, such as hand washing, reducing access to high traffic, maintaining safe social distances, staying at home when sick, avoiding travel, etc.; In addition, the Urban Construction Fangcang Shelter Hospital is no longer a temporary task, but a standard emergency prevention and control facility in the city, which promptly isolates infected people and 100% curbs the spread of sudden outbreaks.
Makeshift hospitals are key to the admission of a large number of asymptomatic infections and mild patients. Makeshift hospitals can quickly concentrate on patients while effectively relieving the strain on local medical resources and ensuring normal medical service needs.
At present, BooCax disinfection robot has rushed to Guangzhou Pazhou makeshift Hospital to carry out the information platform test, in the front line of anti-epidemic, escort makeshift hospital environmental hygiene.
Guangzhou Pazhou Hospital designed nearly 3,450 beds and set up three large areas: pollution area, semi-pollution area, and cleaning area.
Guangzhou Pazhou Hospital designed nearly 3,450 beds and set up three large areas: pollution area, semi-pollution area, and cleaning area. Pavilions 1-5 are designed as five contaminated sections, with a total of about 3,450 beds. Medical and logistical support personnel do not stay in the pavilion, pavilion 6 is the storage area, and pavilion 8 is the semi-polluting area for medical staff to set up a sanitary passing area, it is expected to introduce 8 units of Bubble Fish disinfection robots, distribute 4 in the contaminated area disinfection, and distribute 4 to the nurse station area for disinfection work.
According to BooCax's colleague in charge of the project, the disinfection robot of this "on duty" makeshift hospital is a second-generation aerosol disinfection robot Bubble Fish independently developed by the enterprise. The fuselage has its own child locks and, in the event of various emergencies, promptly activates the pause button of the fuselage to avoid danger, ensure the safety of the scene , and to meet the needs of the actual situation; Disinfection of this area using hypochlorite disinfectant, in the current pandemic, HOC1
It has become the most effective and environmentally safe disinfectant available for a wide range of human pathogens, including the SARS-CoV-2 coronavirus.
Also listed by the United States Environmental Protection Agency N: Disinfectants for use against SARS-CoV-2 (as shown in table 1).
Table 1 Currently Listed Hypochlorous Acid Products Approved by United States Environmental Protection Agency (EPA) for Use Against SARS-CoV-2 as of October 1, 2020
Of course, the European Commission also announced Regulation No. 2021/347 on 25 February 2021, which approved the release of active chlorine from hypochlorite as an active substance for biocides in categories 2, 3, 4 , and 5.
The project staff also mentioned that the indoor disinfection of the Fangcang shelter hospital was carried out by using the maximum amount of 2.6L/H atomization to prevent the epidemic. The frequency of disinfection was as high as 2 hours, which fully ensured the full elimination of the air bacteria in the environment and greatly reduced the spread of the virus; The disinfection robot can work continuously for 2-3 hours, and the disinfection capacity can cover 500m3 space without dead-end, equivalent to the work of 2-3 anti-epidemic personnel.
The newly upgraded Bubble Fish is the only automatic disinfection robot on the market that can atomize disinfectants into small particles within 5 μm. The size of particle value is one of the core indicators of robot elimination performance. Robots generally operate indoors, with relatively stable air temperature, humidity and airflow. Concerning the Brownian principle of motion, the floating time in the air is longer, as shown in the following table; As the size of the particle becomes smaller, the number of particles per milliliter of disinfectant increases significantly, the disinfectant is fully utilized, the small particle disinfectant spreads more quickly indoors, the longer the floating time, the more likely it is to hit the coronavirus in the air, and the elimination will be more thorough.
In addition, the disinfection robot was also used in the 2022 Beijing Winter Olympics. Before entering Beijing Wukesong Stadium, to ensure the disinfection effect of the disinfection robot, The Winter Olympics team invited experts from the Beijing CDC to select a 23m3 room for air sampling. Then put the disinfection robot in the test room for 10 minutes. A sampling of natural bacteria in the air was performed again. Experimental data show that natural bacteria in the air die out at an average rate of > 90.00%. Please refer to the table below :
5.2 requirements for killing microorganisms following the specification of disinfection techniques (2002 edition):
5.2.1 Laboratory Sterilization Test: Disinfectant Effect < = 1 h at 20 ° C, Relative Humidity 50% 70%, Killing Rate of White Staphylococcus in Air (8032) > = 99.90%
5.2.2 Field Test: Disinfectant Effect < = 1 h Under Natural Conditions, The Extinction Rate of Natural Bacteria in Air Should > = 90.0%
Compliant disinfection equipment with compliant disinfectant, combined with the recommendations of the epidemic prevention expert group in the station, customized anti-epidemic prevention plan in various key areas including ticket hall, waiting hall, station hall floor, station shop, etc. At the same time, BooCax Technology matched the intelligent cloud data interface for the makeshift hospital to facilitate the real-time statistics and traceability management of disinfection data.
In addition, Bubble Fish disinfection robots have been widely used in the 2022 Beijing Winter Olympics venues and Olympic hotels. Besides, they are being widely used in medical institutions, hotels, commercial buildings, office buildings, government halls, schools, stadiums and other scenarios throughout the country www.boocax.com .
