Disposable Samples Nylon Flock Oral Nasal Swab Breakpoint Brush Specimen Collection Testing Vtm Swab Tube

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
