First, the test sample is sealed with an isolation bag in the middle. 1. After the nucleic acid detection, it is necessary to put the nucleic acid detection sample into a special sample bag, then seal the bag mouth, spray 75% alcohol or chlorine-containing disinfectant to disinfect the outer surface of the sample bag, and then seal it with a layer of sample bag. The disinfection method is the same as above (the sample bag is appropriate in size and has a biosafety label).
And put the double-layer specimen in the bag? COVID-19? In the sealed transfer box for special specimens, the transfer box is marked with biosafety signs. It has been strictly sealed and disinfected before being put into the transport box, so there is no risk of leakage.
2. Before closing the transfer case, the external surface of the transfer case will be disinfected with chlorine-containing disinfectant or ethanol spray. ?
The specimens in the transfer box should be kept in an upright state to avoid bumping and leakage during transfer.
Three, in addition to the transport box, high temperature disinfection first disinfection. After the collection of samples for nucleic acid detection is completed, the samples are stored and transported in the nucleic acid sample transport box (biological sample transport box) at low temperature to prevent the samples from being degraded by high temperature for a long time before detection, resulting in false negative results.
Detectors take samples from the biosafety cabinet, check the information and heat the inactivated samples to make the virus lose its infection ability. After inactivation, virus nucleic acid extraction and experimental detection were carried out on the samples. At the same time, the nucleic acid detection transport box has also been inactivated and sterilized to ensure that there is no risk of transmission.
Fourth, the empty boxes at the scene have been disinfected. It is reported that the recycled empty transport box was disinfected before it was stolen, and there was no risk of spreading the virus at that time.
Everything happened at the end of the theft, according to the report, there is no risk of transmission.
On the night of the incident, Miao passed by the isolation hotel and accidentally saw a brand-new suitcase in the enclosure of the special area. He couldn't help being moved. This time he didn't check it carefully. When there were few pedestrians on the road at night, he quickly returned to the scene and stole the box. When he got home, he looked carefully and found it on the box. Are there any special biological hazards in COVID-19 nucleic acid samples? Such as words, these words are all outside the box, you can see them when you go home. So it shouldn't be opened. Even if it is opened, as mentioned above, it has undergone strict disinfection, and there is little possibility of risk.
In order to prevent virus infection, Miao quickly put the box back into the snakeskin bag, tied the mouth of the bag tightly, and then thought about how to deal with this hot hand. Sweet potato? . Afraid of being discovered, send it back; Throw it in the garbage for fear that people will call the police; No one will think that their neighbors have been unoccupied for a long time, so they will quietly throw boxes into their neighbors' yards at night. ? So there is no third person touching the transport box, so how can there be a risk of transmission without a transmission chain?
To sum up, five logically clear statements show that there is no spread risk when empty containers are recycled.
