Background Art
[0007] At present, the light sources used by humans are still: lighting light sources can only illuminate, disinfection light sources can only disinfect, and there is no technology or invention for making vaccines through safe light, especially for making broad-spectrum vaccines (vaccines against millions of bacteria, viruses and pathogenic pathogens) in real time through light, and there is no real-time natural vaccination of broad-spectrum vaccines.
[0008] One of the purposes of the present invention is to invent a new light source and equipment that is safe, can allow humans and machines to coexist, can simultaneously perform carrier disinfection (to avoid contact transmission) and air disinfection (to avoid aerosol transmission), is effective against the new coronavirus and millions of broad-spectrum viruses, bacteria, and pathogenic pathogens, and can simultaneously illuminate, disinfect, immunize, and maintain environmental biosafety.
[0009] The promotion and use of the present invention can make human society bid farewell to darkness and usher in light, while keeping away from the infection of millions of bacteria, viruses, mycoplasma, chlamydia, drug-resistant fungi and other microorganisms and the diseases and pain caused by the infection, reduce the frequency of human medical treatment, reduce medical expenses, reduce the use of social security funds, and increase the average life expectancy of human beings. Summary of the invention
[0010] To achieve the above purpose, the present invention provides a 222nm far-ultraviolet new crown and x virus external coupling lighting disinfection immunity multifunctional light source. It includes 1. coupler, 1.1 coupling positive, 1.2 negative electrode, 1.3 ground wire; 2. lamp tube lighting luminous cavity; 4. lighting luminous cavity conduit port; 5. disinfection luminous cavity; disinfection luminous cavity conduit port; 7. high-frequency generator, high-frequency generator positive, negative machine, ground wire; 8 fluorescent powder; 9. glass shell; 10. shielding wire; 10.1 shielding wire positive; 10.2 negative electrode; 10.3 ground wire; 10.4 shielding net; 11. lighting luminous gas; 12 disinfection luminous gas (krcl gas); 13. filter film; 14. buckle, a total of 14 parts.
[0011] The 222-nanometer far-ultraviolet coronavirus and x-virus external coupling lighting disinfection immunity multifunctional light source of the present invention has the following advantages: The present invention can shorten the manufacturing time of vaccines and eliminate the need for storage, constant temperature transportation, appointment for injection and vaccination, and the like.
[0012] Currently: The fastest development time for humans to develop vaccines for infectious diseases with relatively stable antigens is 4.5 years (Merck's mumps vaccine), and the average development time for a vaccine is 8-15 years.
[0013] The development of vaccines for infectious diseases takes time, such as COVID-19. At present, it takes the following steps and time for humans to produce vaccines. (1) A certain number of representative corpses of people who died of the same disease (elderly, young, children, men, women) (2) Collection of a certain number of representative animal carcasses (species that can be transmitted between humans and animals) (3) Autopsy: To identify the organ where inflammation is concentrated or the cause of death, and to take samples of the causative pathogen.
[0014] (4) Pathogen screening, to find or identify the lethal pathogen. (A cryo-electron microscope with a magnification of more than 1 million times is required) (5) Pathogen amplification (6) Inactivation or attenuation of pathogens (temperature method, pressure method, chicken embryo method, MDCK (canine kidney cell) method, recombinant protein method, mRNA method) (7) The vaccine has passed animal testing (8) The vaccine has passed Phase 3 human trials (9) Demonstration and approval for production and use (10) Mass production, constant temperature storage, and constant temperature transportation. (11) Make an appointment for vaccination.
[0015] At least these 11 steps need to be completed. The first 6 steps will take at least 3 months to complete, and the last 5 steps will take at least 6 months. However, after these 9 months, if we encounter a virus like COVID-2019, which has unstable antigen composition, uncertain pathogenic organs (attacks the whole body), rapid mutation of pathogenic pathogens, and especially has immune escape, the vaccine immunity will be ineffective. There are also viruses such as influenza that have a small epidemic every 3-5 years and a pandemic every 5-10 years, which are basically "afterthoughts". Viruses are constantly evolving, and viruses generally replicate once in 6-8 hours, and the iteration is completed in one month. Many people have paid the price of their lives because of the long time for vaccine development and promotion. The current 6 methods of vaccine manufacturing are (1) temperature method, (2) pressure method, (3) chicken embryo method, (4) MDCK (canine kidney cell) method, (5) recombinant protein method, and (6) mRNA method. If the vaccine cannot be completed and vaccinated within 6-8 hours, the current vaccine manufacturing and vaccination will lose to time and the virus, and the tragedy will repeat itself. The present invention only requires two steps: (1) interrupt the RNA\DNA genetic chain of viruses, bacteria, and pathogens through 222-nanometer ultraviolet irradiation to make vaccines; and vaccinate through breathing or contact with nature. Virus replication takes 6-8 hours, while the present invention only takes 10 seconds to interrupt viruses, bacteria, and pathogens. The efficiency is 2160-2880 times that of viruses and bacteria. In the race with viruses, it can beat them in seconds. During the pandemic of infectious diseases, in order to isolate the source of infection, protect susceptible populations, and immunize the human body, "fighting fast with fast and defeating few with more" has won time.
[0016] 222 nanometer ultraviolet light disinfection immune light source and equipment, using 222 nanometer ultraviolet rays that cannot penetrate the stratum corneum of human skin and human cornea, but can interrupt the RNA\DNA genetic chain of viruses, bacteria and pathogens, making the viruses inactive and unable to replicate, achieving the purpose of human-machine coexistence disinfection. At the same time, the envelope protein or spike protein of the viruses, bacteria and pathogens whose RNA\DNA genetic chains are interrupted does not change, which is equivalent to making a "live vaccine". These "live vaccines" enter the human body through breathing or contact, causing the human body's immune response and reaction. After the viruses, bacteria and pathogens whose RNA\DNA genetic chains are interrupted enter the human body, they stimulate the lymphocytes in the human body to produce humoral immunity and cellular immunity. Due to the small number of pathogens entering the human body, the DNA\RNA genetic chain is interrupted and cannot be replicated, and there is no "reinforcement". Relying on its huge immune system, the human body quickly and easily ends the immune "battle" and protects human safety. However, such a "battle" will form immune memory. When the same pathogenic pathogen invades the human body in the future, the human body will quickly mobilize the immune system to defeat the invader and protect human health.
[0017] Under the irradiation of 222-nanometer ultraviolet rays, the virus can be disinfected within 10 seconds. The 222-nanometer ultraviolet disinfection equipment designed and produced by the invention team has been tested by the Chinese Academy of Sciences (China Science Testing Co., Ltd.) and has a 10-second killing rate for coronavirus: 99.98%-99.99%, and a 10-second killing rate for influenza A H1N1: 99.94%-99.98%.
[0018] The 222-nanometer ultraviolet immune disinfection lighting source and equipment of the present invention can be used to disinfect and naturally vaccinate the new crown and a wide spectrum of pathogenic pathogens (millions of species), reducing many links in the production and vaccination of vaccines, saving a lot of time, and winning these pathogenic pathogens in the race against viruses, bacteria, and pathogenic pathogens in seconds, protecting the human body and maintaining environmental biosafety. It is the best technical means and invention for active epidemic prevention at present. It is a subversive technological invention. It can enable humans and animals to win time and victory in the fight against viruses, bacteria, and pathogenic pathogens in the long years to come, and save many lives.
[0019] The use of the present invention can provide strong technical support for the environmental biosafety of human beings on land, water, air, and even manned space stations, outer space, the moon, and Mars bases.
[0020] Existing production lines and supply chains can be utilized, and after applying the present invention, industrialized mass production and large-scale promotion and application can be achieved.
[0021] The present invention, during use, can reduce the frequency of medical treatment, reduce pain, reduce medical expenses, and save social resources.
[0022] The invention is convenient and quick to use during use and is easy to be rapidly promoted and used.

National Health Commission of the People’s Republic of China (1) GB1982-2021 "Hospital Disinfection and Hygiene Standards" of the People's Republic of China (2) Technical Specifications for Disinfection in Medical Institutions WS / T 367-2012 (3) Regulations on the Supervision and Administration of Medical Devices (State Council Decree No. 650) (4) Measures for the Supervision and Administration of Medical Device Production (Order No. 7 of the State Food and Drug Administration) (2) Federal Communications Commission: FCC (3) U.S. Food and Drug Administration: Food and Drug Administration (abbreviated as FDA) (IV) European Medicines Agency: European Medicines Agency (EMA) etc. legal requirements, research and development and creation.
