Disposable virus sampling tube is a virus sampling kit consisting of a storage tube (with virus sample storage solution), a sampling swab and a biosafety bag. Disposable virus sampling tube is suitable for nucleic acid extraction and later virus isolation of influenza virus, avian influenza virus, coronavirus, hand, foot and mouth disease virus, measles virus and other viral samples. It is also suitable for the collection and transportation of specimens of Chlamydia, Mycoplasma, Mycoplasma solium, etc. Samples are usually collected from the oral cavity, pharynx, nasopharynx and other parts of the body.
The body and cap of the disposable virus sampling tube are made of medical polypropylene, which is resistant to high temperature (121), low temperature (-80), static extrusion and dynamic impact. The conical bottom is designed to resist centrifugation and vibration. Built-in sample preservation solution for sample release and preservation to prevent leakage. Built-in glass beads help sample elution. Divided into 10ml, 7ml and 5ml according to the volume of the sampling tube.
The disposable virus sampling tube is not only versatile, but also has product advantages. For external use, it uses plant fluff. The fluffy white hair is soft and suitable for different people. This planning adds up, it is simply broken and good to use. The plastic rods are designed to break easily for transporting specimens. It is important to use disposable sterile packaging, radiation sterilization and individual packaging.
So how do you use disposable virus sampling tubes?
1. Samples are collected using sampling swabs according to sampling requirements (for preservation solutions without swabs, users can provide their own matching swabs).
2. After the sample is collected into the disposable virus sampling tube, place the sampling swab.
3. Break the sampling swab at the easy break point, discard the end, and then close the tube cap.
4. Mark the information on the label of the sampling tube as needed.
5. Samples collected from disposable virus sampling tubes should be shipped to the appropriate influenza surveillance network laboratory within 2 business days at a temperature of 2-8; if they cannot be delivered to the laboratory within 48 hours, set to 70 or save the following and ensure that the collected samples are delivered to the appropriate network laboratory within 1 week. Repeated freezing and thawing of specimens should be avoided.
6. Nasal swab: The collector holds the patient's mandible with the left hand, then gently inserts the swab into the nose of the nasal tract with the right hand, stays for a while, then slowly rotates it 3-5 times and withdraws. Wipe the other side with another swab. Dip the swab head into the sampling solution, squeeze the swab head several times in the sampling solution, break the end of the swab with force, and then discard the end of the swab.
7. Press the patient's tongue with the pharyngeal swab with the left hand that is pressing the left hand. Swab the bilateral pharyngeal tonsils and posterior pharyngeal wall with the right hand swab, dip the swab head into the sampling fluid, squeeze the swab head into the sampling fluid several times, forcibly break the swab tail and discard the swab tail. Nasal and pharyngeal swabs can also be collected in the same disposable viral sampling tube.
