Description

Technical Field

[0001] The present invention relates to the field of medical detection technology, and in particular to a throat swab-based sampling device and a sampling method thereof. Background Art

[0002] Because both breathing and eating pass through the mouth, a wide variety of bacteria live there. These include catarrhal bacteria, various Staphylococci, various Streptococci, diphtheroids, Klebsiella pneumoniae, and Escherichia coli. Anaerobic bacteria also exist, such as Peptococci, Bacteroides, and yeast-like bacteria.

[0003] Influenza is transmitted through the respiratory tract, and the pharynx is where the virus accumulates most. To identify the type of respiratory virus, a pharyngeal swab can be used to quickly and accurately detect the virus.

[0004] Oropharyngeal swabs are a method for collecting clinical test samples from nasal secretions through the throat. The collected samples are analyzed to determine whether there are clinical markers of organisms or other diseases. Compared with nasopharyngeal swab sampling, oropharyngeal swab sampling is a relatively simple detection method. However, in the face of new and emerging infectious diseases such as COVID-19 and SARS, oropharyngeal swab sampling carries a huge risk of cross-infection, which puts tremendous psychological and physical pressure on medical staff. Medical staff need to wear protective clothing to work all day, and the sampling workload is high, consuming a large amount of medical human resources. Summary of the Invention
