Epidemic prevention and disinfection robot is called disinfection robot for short. The robot is the carrier, and the disinfection system is installed inside the robot to generate disinfection gas. Using the pneumatic system of the robot, the disinfection gas diffuses rapidly in the indoor space, which increases the coverage and uniformity of disinfection, and can effectively kill pathogenic microorganisms in the air without dead ends. The disinfection robot can disinfect the room automatically, efficiently and accurately according to the set route.
Second, the disinfection method of disinfection and epidemic prevention robot
Epidemic prevention and disinfection robot has its incomparable advantages in epidemic prevention and control. At present, it can be used in a wide range of scenarios, such as hospitals, airports, customs, shopping malls, hotels, banks, buildings, schools, kindergartens, government agencies, enterprises and institutions, waiting rooms, railway stations, airports and so on. The disinfection robot has the function of multi-scene comprehensive disinfection service, and various functional disinfection robots came into being, such as medical disinfection robot, intelligent disinfection robot, intelligent disinfection robot, multi-scene comprehensive disinfection robot, disinfection and epidemic prevention robot and so on. Under the epidemic situation in COVID-19, the application value of disinfection service function of disinfection robot is prominent, which effectively reduces the risk of virus spreading through droplets, aerosols and objects, and plays an important role in epidemic prevention.
At present, the disinfection methods adopted by disinfection robots are as follows:
1. Ultraviolet disinfection. Ultraviolet disinfection is to destroy the DNA or RNA molecular structure of microbial organisms by using ultraviolet rays with appropriate wavelength, so as to achieve the purpose of killing growing cells or viruses.
2. Disinfectant atomization disinfection. Ultrasonic atomizer can atomize a proper proportion of disinfectant into micron-sized particles, continuously disinfect the air and effectively kill bacteria and viruses suspended in the air.
3. Plasma disinfection. Using bipolar plasma electrostatic field to decompose negatively charged bacteria, polarize and absorb dust, and then combine with secondary sterilization and filtration to keep the controlled environment sterile.
Third, the intelligent disinfection service function of the standardized vaporized hydrogen peroxide disinfection robot
It is a new robot that integrates the functions of hydrogen peroxide disinfection and decomposition, and can move autonomously. It can not only disinfect the closed space efficiently, but also be used to treat the disinfected residue in an environment without ventilation system, and decompose hydrogen peroxide through a self-decomposition device.
Working principle of disinfection robot: The equipment adopts high-speed airflow and flash evaporation technology to vaporize 35% hydrogen peroxide solution into hydrogen peroxide vapor, and introduce hydrogen peroxide into the closed space through pipeline transportation or nozzle. Vaporized hydrogen peroxide molecules contain a large number of hydroxyl radicals, which can attack molecules on cell membranes and bioactive components such as DNA in cells, thus achieving the effect of killing microorganisms. Combined with the walking characteristics of the machine, the hydrogen peroxide is fully diffused in the space, and the disinfection effect without dead angle is achieved in all directions. Using laser sensor, intelligent unmanned disinfection process can be realized.
Compared with the traditional fixed disinfection equipment, the chassis of intelligent mobile robot can carry a single equipment to walk autonomously in different spaces, which greatly improves work efficiency and saves costs. At the same time, the flexible disinfection device makes the disinfectant easier to spread, so that the disinfectant in the whole space can reach the expected concentration quickly and the disinfection is more thorough.
Usage: used for sterilization in closed spaces such as aseptic laboratory, microbiology laboratory, positive control laboratory, sampling room and material transfer room. Intensive care unit (ICU), negative pressure isolation ward/infection ward, laboratory (virus, bacteria), operating room fever clinic, pathology department and laboratory department, dispensing room/intravenous drug dispensing center (PIVAS), supply room, ambulance and other areas. Biosafety laboratory, biosafety cabinet, exhaust high-efficiency filter, and overall disinfection of the laboratory.
