Disposable virus sampling tube is a special container for collecting, storing and transporting virus samples. The following is a detailed introduction about it:
Main components Tube body Usually made of high-quality plastic materials, such as polypropylene (PP), etc. It has a certain hardness and toughness, can withstand extrusion and collision during transportation, and is not easy to break. The tube body is generally transparent or translucent, which makes it easy to observe the state of the sample. The tube body is usually marked with scales to facilitate accurate grasp of the volume of the sample. Preservative solution The preservation solution is a key component in the virus sampling tube. Its main function is to maintain the activity of the virus and prevent the virus from degrading rapidly after sampling. Common preservation solutions are inactivated and non-inactivated. Inactivated preservation solution can quickly kill the virus and make the virus lose its infectivity, while ensuring the integrity of the virus nucleic acid, which is convenient for subsequent nucleic acid testing; non-inactivated preservation solution can maintain the activity of the virus and is suitable for situations where the virus needs to be cultured and separated. The preservation solution usually contains some other ingredients, such as buffers, antibiotics, preservatives, etc., to maintain the stability of the preservation solution and prevent bacterial contamination. Lid The lid is usually made of plastic material and fits tightly with the tube body to ensure the sealing of the sampling tube. A sealing pad or sealing ring is generally provided on the lid to prevent leakage of the preservation solution. Some lids are also designed with special structures, such as leak-proof valves, one-way valves, etc., to further improve the sealing and safety of the sampling tube.
Usage Before sampling, first check whether the packaging of the virus sampling tube is intact and ensure that the tube body and lid are not damaged. According to the sampling needs, choose a suitable sampling method, such as throat swab, nasal swab, sputum, etc. Insert the sampling swab into the sampling site and gently rotate or wipe it to obtain enough samples. Put the sampling swab into the virus sampling tube, break the swab rod, and leave the sampling head in the preservation solution. Tighten the lid of the sampling tube to ensure a good seal. Mark the sample information on the sampling tube, such as sampling time, sample type, patient name, etc.
Application scenario Medical institutions In medical institutions such as hospitals and clinics, virus sampling tubes are widely used to collect samples from fever patients, suspected cases, and close contacts. It can be used to collect respiratory samples (such as throat swabs, nasal swabs), blood samples, fecal samples, etc. for virus detection and diagnosis. CDC Disease prevention and control centers at all levels need to use a large number of virus sampling tubes for sample collection and testing in epidemic monitoring, epidemiological surveys, etc. Sampling can be carried out in different places and different populations to understand the spread and epidemic trends of the virus. Inspection and testing agencies Third-party inspection and testing agencies will also use virus sampling tubes for sample collection and transportation when undertaking various virus testing projects. Ensure the stability and integrity of the samples during transportation to ensure the accuracy of the test results. IV. Precautions Strictly follow the operating procedures for sampling to avoid sample contamination. After sampling, the sample should be placed in the virus sampling tube as soon as possible, and the lid should be tightened to prevent leakage of the preservation solution. Virus sampling tubes should be stored and transported at the specified temperature and time, avoiding high temperature, low temperature or long-term exposure to sunlight. When using sampling tubes with inactivated preservation solution, pay attention to safety and avoid contact with the preservation solution to avoid harm to the human body. Different types of virus sampling tubes may have different scopes of application and methods of use. The appropriate sampling tube should be selected according to actual conditions.
