With the repeated reversal of the epidemic, the fight against the epidemic has become our primary concern for human beings. We must not only prevent the spread of the epidemic, but also protect our own safety, especially the staff who collect virus specimens. If the virus is not collected properly, it is very likely to be infected. Therefore, under such severe tests, the emergence of disposable virus storage tubes has greatly reduced the risk of infection and guaranteed the safety of our frontline personnel.
Specimen collection method
1. Pharyngeal swab: Use two plastic rod swabs with polypropylene fiber heads to wipe both pharyngeal tonsils and posterior pharyngeal wall at the same time, and immerse the swab head in 3ml virus preservation solution (isotonic saline solution, tissue culture can also be used) Or phosphate buffer), discard the tail, and screw the cap tightly.
2. Nasal swab: Gently insert a plastic rod swab with a polypropylene fiber head into the nasal palate in the nasal passage, stay for a while and then slowly turn it out. Take another plastic rod swab with polypropylene fiber head and collect the other nostril in the same way. The two swabs mentioned above were immersed in the same tube containing 3ml sampling solution, the tail was discarded, and the tube cap was screwed tightly.
3. Use an oily marker on the PE tube label to indicate the type of sample, sampling time, number, and patient name.
4. After collection, put the disposable virus storage tube in the special transport box (or vaccine transport box), put it in the ice tray, fill it with soft material, and seal it, and it will be transported by a special person instead of mailing. It is best to use a special vehicle.
5. If the collected specimens cannot be delivered within 24 hours, they should be stored below -70°C as soon as possible. If there is no condition of -70℃, it should be temporarily stored in the refrigerator at 4℃ for a short time, and the specimen should be contacted as soon as possible.
6. Influenza virus is unstable at -20°C to -40°C, so long-term storage is best performed below -70°C.
In this case, it greatly protects us, and it also protects the virus from degrading and causing false negatives. One-time virus preservation tube is a hero to defend in the epidemic.
