[0001] The utility model relates to the technical field of antigen detection, in particular to a pathogen elution test tube. Background Art

[0002] At present, when conducting respiratory pathogen detection, cotton swabs are mostly used to collect nasal mucosal cells and other substances as detection samples. The sampled cotton swabs are placed in a sampling tube, and the cotton swab head is completely immersed in the extract. The cotton swab head needs to be rotated along the wall of the sampling tube for many times, and then the cotton swab head is squeezed and kneaded multiple times through the outer wall of the sampling tube to allow the cotton swab head to release the sample as much as possible to increase the concentration of the sample solution. However, in this process, the extract in the sampling tube is prone to splashing due to improper kneading during the mixing process, and the bottom of the sampling tube is relatively thick, and it may be difficult for some people to press it due to lack of strength, resulting in the elution effect of the pathogens being difficult to guarantee. In addition, when testing a large number of samples, a large number of rotation and squeezing actions are required, which increases the fatigue intensity of medical staff. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 3 The utility model provides a technical solution: a pathogen elution test tube, comprising a tube body 1 and a tube cover 2 movably sleeved on the top of the tube body 1, a liquid outlet 3 is connected to the top of the tube cover 2, a first flexible connecting strip 4 is connected to one side of the tube cover 2, the first flexible connecting strip 4 is connected to the outer side of the tube body 1, a first flexible ring 5 and a second flexible ring 6 are connected to the inner wall of the tube body 1, the second flexible ring 6 is arranged below the first flexible ring 5 and a plurality of the second flexible rings 6 are evenly arranged in the vertical direction, a through hole 7 is provided in the middle of the first flexible ring 5, a first flow guide hole 8 is provided on the outer side of the second flexible ring 6, and a first annular scraper 9 is provided on the inner side thereof, and the tube cover 2 is prevented from being lost through the first flexible connecting strip 4;

[0025] The first flexible ring 5 and the second flexible ring 6 are both flexible to a certain extent, and can be deformed by force, and can recover by themselves after the force disappears. The liquid level of the extract in the tube body 1 is lower than the first flexible ring 5 and higher than the second flexible ring 6. A cotton swab is used to collect nasal mucosal cells and other substances as a test sample. The cotton swab includes a slender rod and a cotton swab head connected to the end of the slender rod. In order to improve the friction and scraping effect between the first annular scraping blade 9 and the cotton swab head, the inner diameter of the first annular scraping blade 9 is less than or equal to the outer diameter of the cotton swab head.

[0026] The aperture of the through hole 7 is smaller than the outer diameter of the cotton swab head and slightly larger than the outer diameter of the slender rod. When the cotton swab head passes through the through hole 7, the first flexible ring 5 is deformed, and the cotton swab head returns to its original state after passing through. The sampled cotton swab head passes through the first flexible ring 5 from the through hole 7 and is immersed in the extract. Then, the slender rod is moved up and down, and the cotton swab head can be scraped against the inner sides of several first annular scraping blades 9, thereby scraping and eluting the sample pathogens on the cotton swab head. There is no need for squeezing and rotating stirring, which is more convenient to use, reduces the fatigue intensity of the user, and has a better elution effect on the pathogens. When the cotton swab head scrapes against the first annular scraping blade 9, the second flexible ring 6 is deformed;

[0027] The first flexible ring 5 is used for blocking to prevent liquid from splashing out of the tube wall when the slender rod is moved, and the cotton swab head can be effectively blocked. Because the aperture of the through hole 7 is smaller than the outer diameter of the cotton swab head and slightly larger than the outer diameter of the slender rod, when the slender rod is moved upward and the cotton swab head abuts against the lower side of the first flexible ring 5, the user can feel a certain resistance, which reminds the user that this is the uppermost position. The user can immediately change to a downward position to prevent the cotton swab head from falling out of the tube body 1 when the slender rod is moved up and down;

[0028] Moreover, the slender rod can be moved and guided by the first flexible ring 5 to prevent the slender rod from sticking to the side wall of the tube body 1, thereby ensuring that the cotton swab head can be inserted from the middle of the first annular scraper 9 with an accurate stroke. By setting the first guide hole 8, when the slender rod is moved up and down, the extract can flow up and down through the first guide hole 8, which not only achieves the effect of pressure relief, but also improves the mixing effect of the extract and the sample, so that the sample is mixed more evenly and fully in the solution, thereby improving the detection accuracy.

[0029] See also Figure 4-Figure 5 In order to improve the scraping and elution effect of the sample pathogens, in this embodiment, preferably, the inner wall of the tube body 1 is connected with a third flexible ring 10, and the third flexible ring 10 is evenly arranged in the vertical direction and is staggered with the second flexible rings 6. The inner side of the second flexible ring 6 is tilted downward, and the inner side of the third flexible ring 10 is tilted upward. The outer side of the third flexible ring 10 is provided with a second guide hole 11, and the inner side is provided with a second annular scraping blade 12. The third flexible ring 10 has a certain flexibility and can be deformed by force. It can recover by itself after the force disappears. In order to improve the friction scraping effect between the second annular scraping blade 12 and the cotton swab head, the inner diameter of the second annular scraping blade 12 is less than or equal to the outer diameter of the cotton swab head;

[0030] The purpose is to make the inner side of the second flexible ring 6 tilt downward, and the inner side of the third flexible ring 10 tilt upward, so that the second flexible ring 6 and the third flexible ring 10 are tilted in opposite directions. When the cotton swab head is pushed downward, the cotton swab head can be mainly rubbed and scraped by the second annular scraping blade 12, and when the cotton swab head is pushed upward, the cotton swab head can be mainly rubbed and scraped by the first annular scraping blade 9, so as to ensure that the side of the cotton swab head can be evenly scraped without dead angles, improve the friction and scraping effect, and then improve the elution effect of the sample pathogen, so that the cotton swab head releases the sample as much as possible to increase the concentration of the sample solution;

[0031] By providing the second guide hole 11, when the slender rod is moved up and down, the extract can flow up and down through the first guide hole 8 and the second guide hole 11, which not only achieves the effect of pressure relief, but also improves the mixing effect of the extract and the sample, making the sample more evenly and fully mixed in the solution, thereby improving the detection accuracy.

[0032] In order to improve the mixing effect of the extract and the sample, in this embodiment, preferably, the first flow guide holes 8 are distributed in a ring array and the second flow guide holes 11 are distributed in a ring array and a plurality of them;

[0033] The purpose is to improve the fluidity of the extract by setting a plurality of first guide holes 8 on the outside of each second flexible ring 6 and a plurality of second guide holes 11 on the outside of each third flexible ring 10, so as to not only achieve the effect of pressure relief, but also improve the mixing effect of the extract and the sample, so that the sample is mixed more evenly and fully in the solution, thereby improving the detection accuracy.

[0034] See also Figure 6-Figure 7 In order to prevent liquid leakage, in this embodiment, preferably, a sealing cover 13 is movably sleeved on the outer side of the liquid outlet nozzle 3, so as to prevent liquid leakage by sleeve-fitting the sealing cover 13 on the outer side of the liquid outlet nozzle 3.

[0035] In order to prevent the sealing cover 13 from being lost and to facilitate opening or closing the sealing cover 13, in the present embodiment, preferably, a second flexible connecting strip 14 is connected to the other side of the tube cover 2, and the second flexible connecting strip 14 is connected to one side of the sealing cover 13. The purpose is to connect the sealing cover 13 to the tube cover 2 through the second flexible connecting strip 14, so as to prevent the sealing cover 13 from being lost and to facilitate opening or closing the sealing cover 13.

[0036] See also Figure 8 In order to improve the convenience of use, in this embodiment, preferably, a suction cup 15 is connected to the bottom of the tube body 1, so that the tube body 1 can be fixed on the table through the suction cup 15, without the need for the user to hold it with hands, thereby reducing the user's fatigue intensity, improving the convenience of use, and effectively preventing liquid from splashing due to hand shaking, thereby improving the reliability and stability of use.

[0037] In order to further improve the convenience of use, in this embodiment, preferably, a protrusion 16 is provided on one side of the suction cup 15, so that after the sample and the extract are fully mixed, the protrusion 16 can be pulled upwards to detach the suction cup 15 from the table, thereby improving the convenience of use.

[0038] The working principle and use process of the utility model are as follows: the sampled cotton swab head is passed through the first flexible ring 5 from the through hole 7 and immersed in the extracting liquid, and then the slender rod is moved up and down, so that the cotton swab head can scrape against the inner sides of the plurality of first annular scraping blades 9 and the plurality of second annular scraping blades 12, thereby scraping and washing away the sample pathogens on the cotton swab head;

[0039] After making sure that enough sample has been released, remove the cotton swab from the tube body 1, or break the slender rod to keep the cotton swab head in the tube body 1, then cover the tube cover 2, and drip the liquid from the liquid outlet 3 into the sample hole of the test card. Finally, by putting the sealing cover 13 on the outside of the liquid outlet 3, the liquid can be effectively prevented from leaking. After the test results are out, all the tools used are put into a sealed bag and disposed of as medical waste.
