|Instruction for use
|1.Sterilization of the sampling tube and swab can be done before the medical institution or the user is used.
2.Annotate the relevant sample information on the sampling tube and inject an appropriate amount of sample solution.
3.According to different sampling requirements, sample swabs were sampled at the corresponding locations, holding the handle gently inserting the swab into the sampling area, gently rotating the swab 3-5 times, and then slowly removing it.
4.The sample is put into the sampling tube, and the sample swab is broken out of the sampling tube, then the tube cover is tightened, and the sample is sealed to complete the sampling.
5.The newly collected clinical specimens should be transported to the laboratory within 48 hours at 4ºC, and can not be sent to the laboratory for 48 hours. They should be kept at -70ºC or below. Specimens sent to the laboratory should be inoculated and separated as soon as possible, and can be stored at 4ºCfor 48 hours. If the inoculum is not inoculated, it should be kept at -70 ºC or below.
6.The conventional sampling methods are as follows:
A) nasal swab: gently wipe the swab head into the nasal passages of the nasal passages, and then slowly exit after stopping for a moment. Wipe the other nostrils with another swab, immerse the swab head in the sample, and discard the tail.
B) pharyngeal swabs: wipe the bilateral pharyngeal tonsils and the posterior pharyngeal wall with swabs, immerse the swab head in the sampling fluid, and discard the tail.
C) gargle: gargle with 10mL normal saline, rinse the head back, make the "Oh" sound, let the saline rotate in the pharynx, and collect the lotion with the 50mL empty sampling tube.
D) nasal lotion: the patient took his posture and his head was slightly backward, injecting 50mL normal saline into the nostril by pipette. He told the patient to simultaneously send K tone to close the pharyngeal cavity, then let the patient lower his head and let out the normal saline, collect the lotion with 50mL empty sampling tube, and repeat the process to wash the two nostrils.
E) nasopharyngeal aspirates: tracheal and bronchial secretions are often collected by this method. Mucus is extracted from the nasopharynx with a collector connected to a negative pressure pump. First, the collector head is inserted into the nasal cavity, and the negative pressure is turned on. The head of the collector is collected and slowly pushed out. Collecting mucus and washing the collector with liquid 5mL for three times.
F) autopsy specimens: autopsy tissue specimens were collected and samples were separated when necessary. Specimens were autopsy tissue.
G) samples of mycoplasma, chlamydia and Ureaplasma samples: male: use sterile cotton swabs to rotate around the urethra about 2cm for a few seconds. Female: remove the mucus from the cervical mucus and insert the 1-2cm into the cervical canal with sterile swab
