The Mission of A Virus Test Swab
From the sampling point to the testing room, then to the temporary storage point of medical waste.
Then to the hazardous waste centre, to the power plant, and finally to the soil.
A swab for nucleic acid detection completed the task and became a piece of pollution-free ash and fill it in the soil.
At present, we are in a critical period of anti-epidemic.
An ordinary hospital has a maximum of 11,220 samples per day at a single sampling point.
The Mission of A Virus Test Swab
At nine o’clock in the morning, at the nucleic acid testing and sampling service point, citizens who were ready to test lined up.
Everyone wears a mask and consciously separates one meter from each other.
At the beginning of the inspection window, the heavily armed nurses washed their hands with an antiseptic solution.
And then removed a flocked swab about 15 cm long from the packaging bag to take a sample before taking the throat swab.
The nurse opened the collector’s mouth wide, and she skillfully inserted the flocked swab into her pharynx.
Then picked up a sampling tube (virus transport medium) with her left hand. And inserted the collection stick into the sampling tube with her right.
With a little force, the tip of the cotton swab breaks enters the sampling tube, seals it. And throws the long stick into the yellow medical waste bin.
As a testing point for ordinary citizens and inpatients, as an ordinary citizen and inpatients, the use of cotton swabs in an ordinary hospital reached 11,220.
Medical waste treatment forms closed-loop management in nucleic acid testing laboratories.
Take the flocked swab, put the swab head into the sampling tube, and paste a barcode similar to “ID card”. And carefully seal it, put it into a transparent sealed box.
And then send it to the transfer cabin of the PCR laboratory of the Department of Infectious Diseases by staff wearing protective clothing.
The PCR laboratory is under negative pressure, and after the virus enters, it cannot come out. After the outbreak, the PCR laboratory strictly abides by the medical waste treatment process, forming closed-loop management of the laboratory.
An hour later, staff in protective suits transported medical waste out of the ward in sealed yellow bags and sealed with “extremely infectious waste”.
Then, the workers send these medical wastes by trolleys to the medical waste temporary storage area at the nucleic acid collection point 100 meters away. For the medical wastes for nucleic acid testing, he transports an average of about 35 kilograms per day.
We need to place the virus sampling tube for 48 hours during the transfer process
Except for professionals, our PCR laboratory does not allow patients and the public to enter here.
To ensure safety, all medical waste from nucleic acid testing collection points, including swab sticks, is kept here for 48 hours.
After our test results come out and are confirmed to be correct, they will be sent to the hazardous waste treatment centre by a medical waste transfer vehicle.
At ten o’clock in the morning, the staff of the hazardous waste centre arrived at the scene. Unload the empty shipping box and load the ship with medical waste that has been sitting for 48 hours.
The sampling flocked swabs used must be incinerated at high temperatures above 1100°C.
There are two buildings, an incineration workshop and a cooking room, in the yard of the Hazardous Waste Center.
The staff in protective suits skillfully unload boxes of medical waste from the transfer vehicle and load boxes of hazardous waste into bucket elevators.
