Kuncreat a medical ozone sterilized air purifier

Principle of ozone sterilization technology: ozone destroys the structure of microbial membrane by the oxidation of oxygen atom to achieve sterilization. The inactivation reaction of ozone to bacteria is always very fast. Different from other fungicides, ozone can react with the double bond of bacterial cell wall lipids, penetrate into the interior of bacteria, act on proteins and lipopolysaccharide, change the permeability of cells, and lead to bacterial death. Ozone also damages DNA by acting on nuclear substances such as purines and pyrimidines in nucleic acids. Ozone first acts on the cell membrane, which damages the components of the membrane, resulting in metabolic disorders. Ozone continues to penetrate through the membrane, destroying lipoprotein and lipopolysaccharide in the membrane, changing the permeability of cells and leading to cell apoptosis.

What is ozone

The molecular formula of ozone is o ₃. It is a sky blue odor gas with dark black liquid and blue black solid.

Ozone mainly exists in the ozone layer below the stratosphere 20 km from the earth's surface. It absorbs, blocks and weakens short wave ultraviolet rays harmful to human body and prevents them from reaching the earth.

Ozone sterilization

The mechanism of ozone sterilization is that oxidation destroys the structure of microbial membrane to achieve sterilization. The inactivation reaction of ozone to bacteria is always very fast. Different from other fungicides, ozone can react with lipid double bond of bacterial cell wall, penetrate into the interior of bacteria, act on protein and lipopolysaccharide, change cell permeability, and lead to bacterial death. Ozone also damages DNA by acting on nuclear substances such as purines and pyrimidines in nucleic acids. Ozone first acts on the cell membrane, which damages the components of the membrane and leads to metabolic disorder. Ozone continues to penetrate through the membrane and destroys the lipoprotein and lipopolysaccharide in the membrane, changing the permeability of cells, leading to cell dissolution and death. Ozone inactivation of the virus is considered to be completed by the direct destruction of its RNA or DNA material.

Field of indoor disinfection

Ozone has the function of killing bacteria and viruses in the air and reducing dust. It can make the air fresh and natural, eliminate fatigue and refresh the mind.

Health care

The hospital is the place to treat diseases, but because most of the people who go to the hospital are critically ill patients, the inflammation is in the peak period, and the harmful bacteria from the patients are easily distributed in the air. Therefore, the hospital is also a place easy to be infected with diseases. Therefore, it is common to see a doctor in a hospital causing cross infection. The disinfection of hands and surgical instruments of doctors or nurses before operation and nursing operation is also one of the problems to be solved. Ozone, which has high efficiency and rapid bactericidal effect, can be widely used in hospital environment disinfection and preoperative disinfection. For example, Japanese scientists have studied ozone water disinfection for hospitals. According to the research results, ozone water can kill all the bacteria in the hands of doctors and nurses before operation, which is not only very short in time, but also incomparable to other iodine disinfectants. It takes at least 10 minutes to perform the same disinfection. In the hospital, Staphylococcus aureus and Pseudomonas aeruginosa, which are the most susceptible to infection in the hospital, can be completely killed in 5 seconds in ozone water, and its bactericidal power is far more than that of alcohol and chlorine. And ozone water has reliable safety, often used will not hurt the skin, even if drunk by mistake will not be poisoned.

Ozone can also be used for treatment. For example, Russia has developed a special hydraulic fluid to cure the wound. Its basic method is to wash the wound with a mist of physiological solution rich in ozone under high pressure. The water flow is like a scalpel to remove the pus, necrotic tissue and bacterial decomposition in the wound, and kill pathogenic microorganisms on the surface of the wound. Then, the structure of the "ozone knife" is changed, and the pressure of the liquid is continuously increased, so that the ozonized solution seeps into the inflammatory tissue a few millimeters to 3 cm deep, and oxygen is added to kill the deeper pathogenic bacteria. It is reported that 200 patients with diabetes, sepsis, arteriosclerosis and unsuitable for routine surgery have been treated with this method. As a result, the wounds of these patients have been completely healed.

Through the understanding of the above information, ozone sterilization technology is very mature. However, there are still some deficiencies in the ozone sterilization air purifier. The medical sterilization air purifier developed by Kun innovation solves the disadvantages of traditional ozone sterilization. For traditional ozone sterilization, we know that it takes about 30 minutes for ozone to decompose into oxygen or oxygen under normal temperature and pressure However, the intuitive efflux of ozone is easy to cause damage to human respiratory tract, and the advantages outweigh the disadvantages. If the equipment can monitor the ozone concentration and ozone decomposition cycle system in real time, it will be better for human beings; therefore, Kunchuang company develops a medical air sterilization device, which can effectively avoid the occurrence of the above situation, and effectively solve the above problems.

Kunchuang invention provides a medical sterilization air purifier. The server is fixed on the inner wall of the purification box, the lower part of the server is provided with a control main board, and the purification box and the lower part of the server are provided with a heat dissipation device. The medical sterilization air purifier provided by the invention has a high-speed fan to drive the air to pass through the microporous ozone decomposition filter screen and flow to the ozone sterilization bin above the microporous ozone decomposition filter screen for reaction. After the reaction in the ozone sterilization bin, the air also reacts with the VOC filter screen for formaldehyde removal, so as to facilitate the air inlet
