Medical wall-mounted air sterilizers are often used in public places such as hospitals, stations, schools, and so on with a lot of people. The so-called medical air disinfection machine is naturally a machine that sterilizes the air. When the medical air disinfection machine disinfects the hospital room, it generally uses physical or chemical methods to disinfect and eliminate pathogens and pathogens in the hospital environment and transmitted materials. Other microorganisms harmful to the human body, or through disinfection, make these harmful substances harmless. When the air disinfection machine is used to clean the hospital environment, the principle is to use some special materials, but also to use physical principles to clean the air in the environment and remove the bacteria in the air to achieve the purpose of cleaning the air. These are some of the important working principles of the medical air sterilizer, and the combination of physical and chemical disinfection is also quite thorough. With the current development of science and technology, more and more high-tech sterilizers have been developed to contribute to medicine. So today, I will introduce how to use the medical air disinfection machine. What should you pay attention to when using the air disinfection machine: About the use of the air disinfection machine: First, turn on the power, if the red indicator light is on, it will enter the standby state ; Then press the switch button, the red indicator light turns green, and the damper will automatically turn on the natural wind of the project; select the working mode of the disinfectant, ozone disinfection or ultraviolet disinfection, the corresponding indicator light will light up; set the current time, Determine the stop and change of time data and confirm the validity of the data. There are two main types of medical air disinfection machines. One is ozone disinfection and the other is ultraviolet disinfection. The ozone formed by the former can complete the oxidation in a short time under the condition of low concentration; when it is very small There will be a fresh breath in the case of the amount; the latter kills bacteria and germs in the air through ultraviolet radiation, so that the DNA components in the body are destroyed, so that they can die or reproduce. Loss of ability. Precautions for medical air disinfection machine: 1. Disinfect and sterilize the indoor space applicable to the model regulations, and cannot be used beyond the space. If you cannot avoid increasing the disinfection time appropriately; 2. Pay attention to the airtightness of the room: When the air disinfection machine is working, the doors and windows should be closed to maintain good airtightness in the room. It is strictly forbidden to enter the room. Disinfection must be carried out in an unmanned environment to ensure the disinfection effect; 3. Pay attention to the surface hygiene of indoor objects: medical air disinfection machines are only effective for bacteria and viruses in the air, and have no disinfection effect on the surface of objects; but ozone disinfection has a certain effect , But the effect is not good. If there is a lot of dust on the surface of indoor objects, the air sterilizer will produce secondary dust when it is working, causing continuous air microbial pollution, and eventually resulting in unsatisfactory disinfection effect within the specified time, or even failure to reach the standard. This is also after normal disinfection in normal hospitals The reason for the unqualified bacterial culture or the increase of bacteria during the disinfection process is not reduced. Therefore, it is best to clean and disinfect the floor, the lower half of the wall and the surface of various indoor objects before using the air disinfector. In an environment with high disinfection requirements, you can also clean the walls and ceilings every month. Disinfect 1 to 2 times. In addition, it is not advisable to hang curtains and other items that are easy to attract dust or dust; 4. The choice of air disinfection startup time: (1) Preventive disinfection: use program-controlled scheduled disinfection twice a day, each time you turn on the machine 120min. It is generally arranged from 6 to 8 in the morning before work and 12 to 14 in the afternoon before work. (2) Temporary disinfection: the purpose is to control and reduce the secondary pollution of ambient air during personnel activities. It is usually carried out during peak periods of personnel activities, or after surgery, such as changing the clean bed unit, consultation and rounds, etc. 5. The air disinfection machine adopts the C-band ultraviolet sterilization technology and the principle of physical filtration and disinfection. Therefore, the space around the disinfection machine should be prevented from being blocked by larger objects to ensure unobstructed air flow. The good circulation of air should be protected as much as possible to achieve indoor circulation. The disinfection effect.
