Embodiment 1
[0031]Embodiment 1: Preparation of antibacterial and antiviral spray on oropharyngeal surface and hand surface
[0032] Specifically, take the preparation of 100ml oropharyngeal face and hand surface bactericidal antiviral spray as an example:
[0033] (1) Based on the preparation of 100ml of spray, add 70ml of hydrogen-rich water to the stirring tank at room temperature, then add 0.2g of lysozyme to 4 million units / 100ml, 0.1g of tetrapyridyl ammonium chloride, and glycyrrhizic acid 0.01g, 0.03g acesulfame potassium, 0.1g menthol, dilute hydrogen-rich water to 100ml, stir until completely uniform and set aside;
[0034] (2) Test the pH value to determine whether the pH value reaches 6.0-6.8. If the pH value is between 6.0-6.8, it can be filled; if the pH value is not up to the standard, adjust the pH value to 6.0-6.8 with citric acid. Or more preferably 6.3.
Embodiment 2
[0035] Embodiment 2: Disinfection evaluation of antibacterial and antiviral spray on oropharyngeal surface and hand surface
[0036] 2.1 Microbial killing test
[0037] 2.1.1 Preparation of bacteria suspension and bacteria slices Bacterial species: Escherichia coli 8099, Staphylococcus aureus ATCC6538, Pseudomonas aeruginosa ATCC15442, Candida albicans ATCC10231.
[0038] 2.1.2 The test was carried out according to the bactericidal test method stipulated in the 2002 edition of the "Technical Specifications for Disinfection".

[0041]
[0042] 2.2 On-the-spot experiment of oral and facial antibacterial and antiviral sprays on oral disinfection
[0043] 2.2.1 At the site of use, randomly select subjects. The test shall not be less than 30 person-times.
[0044] 2.2.2 Before disinfection, the subject washes his hands, rinses his mouth with water, soaks it in a test tube containing 10ml of diluent with a s...
Embodiment 3
[0052] Example 3: Protection evaluation of antibacterial and antiviral spray on oropharyngeal surface and hand surface
[0053] 3.1 Antibacterial zone method to test the bactericidal and antibacterial effect of oral and facial antiviral spray
[0054] 3.1.1 Prepare 2 bottles of 100mL LB liquid medium (yeast extract 5g / L, tryptone 10g / L, NaCl 10g / L, agar powder 15g / L), autoclave at 121°C for 20min, and insert Escherichia coli respectively after cooling 1 slant strain, 1 slant strain of Staphylococcus aureus. Shake well and incubate at 37°C for 1-2 days until cloudy.
[0055] 3.1.2 In the ultra-clean workbench, put 100mL of nutrient agar medium at about 45°C, shake well, then pour the medium into a dish, wait for it to solidify, and pour it into 4 petri dishes. Use a sterile pipette to draw 0.2 mL of Escherichia coli (8099) suspension and 0.2 mL of Staphylococcus aureus (ATCC6538), and spread them on the culture medium.
[0056] 3.1.3 Take the sterile circular filter paper pi...
