Most citizens never wash their headphones
Prior to the implementation of the practice, the reporter held a random interview with the citizens in Wuchang, Nanchang. Citizen Limys reported that she likes to wear headphones and listen to music. Her use of headphones is very high, but she has never washed her headphones. "Shouldn't there be a few bacteria?"
The public teacher Zhang also showed that he had never washed his earplugs. “The ear plugs are used by themselves and they shouldn’t be as dirty as they need to be.†However, Teacher Zhang also asked the question: “If I want to liquidate, How should we liquidate? Use clean water as a special disinfectant?"
The question of similarity exists among the majority of the people that the reporter randomly interviewed. Only a few citizens showed that if they saw dirt on their headphones, they would wipe them with paper towels or wipes, but there was no custom for washing.
In-ear headphones are more sensitive to bacteria than in-ear headphones
Implementing props: Three used headphones, one for ear-plugs, two for ears, and two for ear-plugs.
Implement things: sterile saline, sterile straw, sterile dish, medical sterilization cotton swab, etc.
Implementation staff: Central Inspection Section of CDC in Xihu District of Nanchang City should be brilliant (Note: The effect of this implementation will only be implemented for this time)
In-ear headphones can enter the external auditory canal
The reporter sent Zhao's three pairs of headphones to the Central Inspection Section of the CDC. Two pairs of earbud style earphones, when used, were inserted on the inner ear wheel and would not be probed into the external auditory canal. The other pair of in-ear headphones could be directly extended. Go into the external auditory canal and fight with the skin on the ear canal. Which kind of headphones buried more bacteria? Speaking without a word, it is true.
Actress Ying Yan began to disinfect the No. 1 earphone, then smear the sample with a cotton swab, put the swab into a test tube, and inject 10 ml of 0.9% sterile saline into the test tube and shake it. Allows the bacteria on the swab to be evenly confused in saline. Afterwards, the operator removed 1 ml of the solution from the test tube, poured it on a sterile plate, and participated in the creation of the base.
In the No. 2 and No. 3 headphones, before the implementation of the headset, the operator wore the left ear of both headsets for an hour, and the right ear was connected. Afterwards, the operator also sampled the No. 2 and No. 3 headphones. After all 3 headsets were properly sampled, the operators placed 5 flat plates into the 36°C box to create bacteria.
Wearing 1 hour of bacteria breeding nearly 5 times
After 48 hours, the reporter saw that 4 out of 5 tablets had only white freckles. The operator showed that this was a colony formed after the 48-hour period, and there were several more white spots on several colonies. The reporter invented that the only thing that did not have white spots was the sampling on the headphones after sterilization.
Afterwards, through the implementation of the personnel calculation, the No. 1 earphone was aseptically dropped; the No. 2 earphone was a sample after wearing for 1 hour; the colony was 120; the right ear was a headphone with no disposal penalty; the colony was 25; and the No. 3 earphone was left ear It was also the sample after 1 hour wearing, 25 colonies, and the number of colons in the right ear without disposal penalty was 9. It can be seen that in-ear headphones are more sensitive to bacteria than in-ear headphones. In-ear headphones were about five times more germ-bearing than they were before wearing them for an hour, and germs were nearly three times more proliferated than before.
The operatives should perform brilliantly. Bacteria usually undergo vegetative propagation in a simple two-breaking process. The breakdown time is usually 20 to 30 minutes. Therefore, from this point of view, wearing an hour's earphone, the bacteria can multiply up to 5 times, and if they do not wash for a long time, they will accelerate the growth of bacteria.
