Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to a sampling device. Background Art

[0002] A swab refers to a small ball of absorbent material (such as cotton) wrapped around one end of a small stick, usually used as a tool for medical examinations to collect microorganisms, exfoliated cells or secretions. Swabs include throat swabs, nasal swabs, etc. The routine standard process for throat swabs is: after the sampler (mainly medical workers) wears protective equipment such as masks and gloves, he lights an alcohol lamp and asks the person being sampled to rinse his mouth and then open his mouth wide and make an "ah" sound to expose the throat. If necessary, use a tongue depressor to press the tongue down to fully expose the throat. Take out the throat swab from the culture tube, gently and quickly wipe one side of the palatine arch, pharynx, tonsils and the other side of the palatine arch, disinfect the mouth of the test tube over the flame of the alcohol lamp, and finally insert the throat swab into the test tube, plug the bottle stopper and send it for inspection.
