Product Description

Swab of nose and throat for virus specimen collection









Expected usage
1.Virus sampling tubes are used for the collection and transportation of clinical influenza, avian influenza (such as H7N9), viral bacteria on hands, hand-foot-mouth virus, measles and other virus specimens, as well as chlamydia, mycoplasma, ureaplasma, anaerobic bacteria, aerobic bacteria, and chlamydia samples .
2. Virus sampling tube is used for storage and transportation of viruses and related samples within 48 hours under refrigeration (2-8 degrees).
3. Virus sampling tube is used for long-term storage of viruses and related samples in -80 degree environment or liquid nitrogen environment.
Inspection principle
Viruses are composed of a nucleic acid molecule and protein or only protein. The individual is tiny and the structure is simple. Because there is no cell structure, the virus cannot replicate itself, but invades the gene into the host cell and uses the latter's replication system to replicate the new virus. After the virus sample is collected, in order to maintain the activity of the virus sample and prolong the survival time of the virus in the sample, the swab will be placed in a preservation solution for storage and transportation.

Main components

Serial number	composition	30 servings / box	50 servings / box
1	1 storage tube (including 3ml sample solution)	3ml × 30 tube	3ml × 50 tube
2	Sampling swab	30 pcs / box	50 pcs / box
3	Instructions	1 serving	1 serving

Storage conditions and expiration date
Store at room temperature, store in a dry and ventilated place, beware of moisture, and should not be stored together with toxic or special odor items, avoid direct contact with fire sources and flammable and corrosive substances.

Scope of application
Used for sample collection, transportation and storage.

Virus storage tube Main components
Hank 's solution, gentamicin, fungal antibiotics, BSA (V), cryoprotectants, biological buffers and amino acids.
On the basis of Hank 's, the addition of virus stabilizing ingredients such as BSA (Bovine Serum Albumin Fifth Component) and HEPES can maintain the activity of the virus in a wide temperature range, reduce the rate of virus decomposition, and increase the positive rate of virus isolation.

Instructions
1.Medical institutions or users can sterilize sampling tubes and swabs before use.
2.Mark the relevant sample information on the sampling tube and inject the appropriate amount of sample storage solution.
3.According to different sampling requirements, use a sampling swab to sample at the corresponding part, hold the handle to gently insert the sampling swab into the sampling site, gently rotate the sampling swab 3-5 times, and then slowly take out.
4.Put the extracted sample into the sampling tube, break the part of the sampling swab that is higher than the sampling tube, then tighten the tube cap and seal it to complete the sampling.
5.Freshly collected clinical specimens should be transported to the laboratory within 48 hours at 4 ° C. Those that cannot be sent to the laboratory within 48 hours should be stored at -70 ° C or below. Specimens should be inoculated and separated as soon as possible after being sent to the laboratory. Those that can be inoculated and separated within 48 hours can be stored at 4 ° C. If it fails to inoculate, it should be stored at -70 ºC or below.
6.The conventional sampling methods are as follows:
a)Nasal swab: Gently insert the swab head into the nasal palate in the nasal passages, and after a while, slowly turn to exit. Use another swab to wipe the other nostril, immerse the swab head in the sample solution, and discard the tail.
b)Pharyngeal swab: Use a swab to wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall. Immerse the swab head in the sample solution and discard the tail.
c)Mouthwash: Gargle the mouth with 10mL saline, let the patient's head tilt back slightly, make an "Oh" sound, let the saline rotate in the pharynx, and collect the wash with an empty 50mL sampling tube.
d)Lotion: The patient takes a sitting position, tilts her head slightly back, injects 50 mL of normal saline into one nostril with a pipette, and instructs the patient to simultaneously sound K to close the pharyngeal cavity. Then let the patient bow his head to let the saline flow out, collect the lotion with an empty 50 mL sampling tube, and repeat this process to wash the nostrils on both sides.
e)Nasopharyngeal extract: Tracheal and bronchial secretions are often collected using this method, and a mucus is drawn from the nasopharynx with a collector connected to a negative pressure pump. First insert the collector head into the nasal cavity, turn on the negative pressure, rotate the collector head and slowly push it out. Collect and draw the mucus, and rinse the collector three times with 5 mL of the collected solution.
f)Autopsy tissue specimens: Collect autopsy tissue specimens if necessary to separate sample components. The specimen is autopsy tissue.
g)Samples of mycoplasma, chlamydia, ureaplasma: male: insert a sterile cotton swab into the urethra to rotate about 2cm, and rest for several seconds Female: Wipe the cervical mucus, insert a sterile swab into the cervical canal 1-2cm to take the material.

Contraindications and precautions

1.Disposable samplers should be sent for inspection as soon as possible after sampling, and immediately be transported at a low temperature of 2-8 ° C. The collected samples can be stored at 2-8 ° C for a short period of 48 hours; Or store at -196 ºC.
2.This product is strictly prohibited for the sampling of bacterial samples. The antibiotics contained in the preservation solution itself have an inhibitory effect on bacteria.
3.It is forbidden to directly touch the collected patient, or to sample the patient after wetting the swab.
4.Sampling should be carried out in strict accordance with the sampling procedure, so that the sampling location is accurate and the sampling strength is uniform and suitable, otherwise it will affect the quality of sample collection.
5.Do not use the product after the expiration date or the product packaging is damaged.
