Disposable sampling tubes are a set of centrifuge tubes used for sampling and transporting microbial sampling tubes for influenza, hand, foot and mouth disease and other diseases, also known as specimen transport tubes, which are becoming commercialized products. Disposable disease sampling tube has the following main components, what are they? Let's all take a brief look below.
1. Disposable sterile plastic rod/rayon tip sampling swab.
2. Sterile sampling tube containing 3 ml of retention fluid (selection of gentamicin and penicillin B can better reduce other substances in the sample. Avoid possible human sensitization reactions caused by penicillin in traditional sampling solution. In addition, there are additional parts such as tongue plate and biological bag.
What is the use of disposable sampling tubes?
1. Used by health control departments and clinical departments for monitoring and sampling of infectious disease source microorganisms.
Suitable for influenza (common influenza, dental avian influenza, influenza A (H1N1), etc.), hand, foot and mouth disease and other types of sampling. Also used for sampling of mycoplasma, chlamydia, urease, etc.
2. Used for transporting nasopharyngeal swab specimens or specific sites from the sample site to the testing laboratory for PCR extraction and examination of tissue specimens.
3. Nasopharyngeal swab specimens or used to preserve specific sites for necessary cell culture.
What are the requirements for disposable sampling tubes? Sampling tubes are loaded with inaccessible substances, some of which are highly pathogenic and sexy, so the requirements for packaging containers are very demanding, so they must meet the requirements of three aspects at the same time.
1. Transportation. Ensure that the sample does not leak during transportation. Meet the WHO regulations and biological regulations of the sample management.
2, storage. Ensure that samples do not leak during storage. Sample tubes in compliance with WHO regulations and biological regulations.
3. Samples. Prevent the sample tube itself from having a toxic effect on the sample.
What is the use of disposable sampling tubes? Let's all take a brief look below.
Tear along the end of the disposable sample tube envelope, cut or tear the bag, remove the preservation fluid and sample swab, and display the relevant sample information on the label of the custody tube or affix a barcode label before taking the sample. Remove the sample swab (if the sample swab is individually wrapped, just tear the easily torn part from the end of the bag) and take the sample at the appropriate site according to the sampling requirements. Pharyngeal sampling: first press the tongue, extend the head of the sample swabber to the throat, wipe the bilateral pharyngeal tonsils and the posterior wall, gently turn, and take a full sample. Nasal sampling: the head of the swab is gently inserted into the nostrils of the nasal cavity, stay for a while, and slowly turn away from the field. To collect samples from both nostrils, simply repeat the operation using the other sample.
After taking the sample, place the sample swab quickly into the storage tube. Broken sample swab: Dip the sample swab tip into the storage solution, break the sample swab, remove the sample handle and tighten the tube cap. Inserted sample swab: Dip the head of the sample swab into the preservation solution, insert the upper end of the sample swab into the small hole inside the lid and tighten the lid. Newly collected samples should be shipped to the laboratory within 4 to 48 hours, and nucleic acids should be extracted and purified quickly for nucleic acid testing. For strain culture isolation should be planted in other media or culture solution as soon as possible. 48 hours failed to send to the laboratory, should be stored at -40 ~ -70. specimens sent to the laboratory, should be inoculated as soon as possible to isolate, 48 hours inoculation can be isolated can be stored at 4 ℃.
The above is a simple analysis of how to use disposable sampling tubes, I hope to help you.
