[0002] In a conventional nucleic acid detection process, nasopharyngeal swab is an important collection method. However, in the process of collecting virus by conventional nasopharyngeal swab, a single packaged sterile cotton swab is used to swab deep into the nasal cavity and throat in clinic, and after sampling is completed, the sampling cotton swab head will be attached with a large amount of bacteria and viruses. At this time, the sampling cotton swab may be easily exposed to the air for a long time due to manual operation, space movement and other problems, thereby greatly increasing the risk of virus transmission and cross-infection. In addition, during the sampling process in clinic, one hand holds the sterile cotton swab, and after the cotton swab takes out the specimen, the other hand needs to loosen the virus culture tube, which undoubtedly increases the exposure time of the virus in the air and the complexity of the operation.

[0003] The above problems are very serious. Considering the complexity of the operation and the difference in the reaction ability of the sampling personnel, and all cannot completely put the swab into the virus culture test tube immediately, which does not meet the "rapid" standard of the sampling procedure of virus detection. In view of the characteristics of fast virus transmission speed and the difference in the reaction ability of the operating personnel, there is an urgent need to develop a multifunctional nasopharyngeal swab collection device for avoiding cross-infection risk to reduce the risk of virus cross-infection between medical personnel and test personnel and the complexity of nucleic acid sampling operation, which is particularly important for precision medicine and is a hot topic in today's society.

[0070] Step preparation:

[0071] In the initial state, firstly, the automatic capping system of the sterile virus loading cavity is in the closed state, and the virus culture solution ring cavity 27 is filled with a certain amount of culture solution required by the virus; secondly, the virus cotton swab collection handle 3 is installed through the swab collection handle feeding system; then, the advancing device shell 54 and the disassembled tubular virus loading shell 9 in the virus culture solution filling system are connected through the locking block 10 with a sliding hole in the tangent action of the positioning and locking slide 12. Finally, the push-pull integrated button 17 is at the push-pull integrated import and export slide 23 position and waits for sliding to start.

[0072] The step flow is as follows:

[0073] When the work starts and the sampling is in progress, the push-pull integrated button 17 enters the axial collection slide 19 and moves forward; at this time, the sampling virus cotton swab collection handle 3 is pushed by the separated long push rod 36 and is rolled by the plastic ball 4 to open the lower annular ball cover 2. The sampling virus cotton swab collection handle 3 slowly enters the nasopharynx, and medical personnel can appropriately and reasonably select the first circumferential slide 13, the second circumferential slide 14, the third circumferential slide 15 and the fourth circumferential slide 16 according to the age of the tested person and the depth of the nasopharynx. When the push-pull integrated button 17 selects the slide position, it is slowly rotated along the circumferential direction of each slide and stays in the state for the virus sampling time required by the state, so as to collect more viruses in the nasopharynx. After the sampling is completed, the push-pull integrated button 17 moves along the axial collection slide 19 and moves backward, and at this time the sampling virus cotton swab collection handle 3 is closed by the rolling action of the plastic ball 4 to close the lower annular ball cover 2, and at the same time the telescopic plastic spring 6 between the first spring hanging ring 5 and the second spring hanging ring 24 starts to shorten, and the sealing work of the lower annular ball cover 2 is completed. Further, the swab collection handle feeding system starts to work, the push-pull integrated button 17 moves backward along the virus filling liquid axial slide 21, and when the push-pull integrated button 17 slides along the axial collection slide 19, the push-pull integrated button 17 slides into the installation and unloading axial slide 22 at this time, according to the principle that the long side of the rectangle is greater than the width, the rectangular baffle 48 is pressed against the circular baffle 53 with a rectangular hole, and the toothed engagement arc-shaped piece 31 releases the virus cotton swab collection handle 3, at this time the virus cotton swab collection handle 3 will fall into the virus culture liquid discharge cavity 25 along the rectangular collection channel 28. Further, the virus culture liquid supply system starts to work, the push-pull integrated button 17 slides into the virus filling liquid circumferential slide 20, at this time the rectangular baffle 34 with a positioning port and the rectangular baffle 48 pass through the circular baffle 53 with a rectangular hole and simultaneously occur 90° horizontal flip. The push-pull integrated button 17 moves forward along the virus filling liquid axial slide 21, and at the same time, according to the principle that the long side of the rectangle is greater than the width, the rectangular baffle 48 can continue to send the virus cotton swab collection handle 3 to the virus culture liquid discharge cavity 25, and at the same time can press the piston connecting piece 30 and drive the rectangular hole waterproof rubber piston 29 to release the virus culture liquid ring cavity 27 into the virus culture liquid discharge cavity 25 through the discharge hole partition plate 26. Further, the push device shell 54 and the disassembled tubular virus loading shell 9 in the virus culture liquid filling system are disassembled through the positioning boss 10 with a sliding hole in the tangent action of the positioning locking slide 12, and the loading cavity rubber sealing cover 11 is covered. The push-pull integrated button 17 returns to the initial state starting point, and the whole collection process is completed.
