Gram-positive staining. With the extension of the culture time or the death of the bacteria, it can show Gram-negative staining. Without flagella and without forming spores. Group A streptococcus has a hair-like M protein and a pilus structure wrapped with lipoteichoic acid. Most group A streptococci can form a hyaluronic acid capsule in the early stage of culture (2 - 4 hours), and with the extension of the culture time, it disappears after being degraded by the hyaluronidase produced by the bacteria.
[0003] When detecting group A streptococcus antigen, a detection kit is required. When detecting with the detection kit, the extraction solution needs to be dropped into the test tube first, and then the cotton swab with bacteria is put into the test tube and left standing for 3 - 5 minutes. Then the cotton swab is taken out, and the extraction solution in the test tube is dropped onto the test paper inside the detection kit through the medicine adding port of the detection kit. This method is simple to operate, but it requires the staff to transfer the extraction solution, and the extraction solution is easily polluted by the external environment during the transfer process, affecting the detection effect. At the same time, it is not convenient for the storage of the cotton balls, and a separate storage device needs to be prepared, which is not conducive to the use of the staff. Therefore, a rapid detection kit for group A streptococcus antigen is proposed for the above problems. Content of the Utility Model

A medicine adding mechanism is arranged at the medicine adding port 3 of the kit main body 1.
[0023] As a further improvement of the present utility model, as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the medicine adding mechanism includes a test tube 4 fixedly connected to the main body 1 of the test kit, and the test tube 4 is fixed at the medicine adding port 3. The inner side of the bottom end of the test tube 4 is fixedly connected with a bottom shell 8. The top end of the test tube 4 is fixedly connected with a threaded ring 5. A puncturing assembly is arranged at the bottom of the test tube 4. During use, the extraction solution is directly placed inside the test tube 4. At the same time, the bottom shell 8 plays a role in sealing the bottom of the test tube 4, and the extraction solution is also stored inside the bottom shell 8. At the same time, the head of the cotton swab 13 is immersed in the extraction solution. After standing for 3 - 5 minutes, the staff pulls the cotton swab 13 upward by the handle of the cotton swab 13, so that the head of the cotton swab 13 is separated from the extraction solution. Then, the staff squeezes the test tube 4 on both sides of the head of the cotton swab 13, and squeezes the head of the cotton swab 13 through the test tube 4, so that the liquid on the head of the cotton swab 13 flows into the inner side of the bottom shell 8. Finally, the extraction solution inside the bottom shell 8 will flow into the inner side of the medicine adding port 3 through the punctured bottom shell 8, and the extraction solution will also contact the test paper 2 inside the medicine adding port 3. This reduces the transfer steps of the extraction solution, facilitates the use of the staff, and the extraction solution directly falls into the inner side of the medicine adding port 3 from the test tube 4, reducing the contact time of the extraction solution with the air and reducing the probability of the extraction solution being contaminated, thereby improving the accuracy of the detection.
[0024] As a further improvement of the present utility model, as Figure 1 , Figure 2 and Figure 3 shown, the test tube 4 and the bottom shell 8 are made of the same material, and both are made of soft plastic of PE material. The test tube 4 and the bottom shell 8 made of soft plastic can ensure that the staff can squeeze the test tube 4 by hand, and at the same time can ensure that the puncturing assembly can puncture the bottom shell 8.
[0025] As a further improvement of the present utility model, as Figure 3 shown, the puncturing assembly includes a first button 9 fixedly connected to the test tube 4. The other end of the first button 9 is fixedly connected with a needle 10. The test tube 4 is fixedly connected with a second button 11 on the opposite side of the first button 9. The other end of the second button 11 is fixedly connected with a connecting cylinder 12. The staff holds the first button 9 and the second button 11 by hand, so that the first button 9 and the second button 11 drive the corresponding needle 10 and the connecting cylinder 12 to squeeze the bottom shell 8. At the same time, the needle 10 will puncture the bottom shell 8 and enter the inner side of the connecting cylinder 12. Then, the needle 10 is separated from the connecting cylinder 12. At this time, the extraction solution inside the bottom shell 8 will flow into the inner side of the medicine adding port 3 through the punctured bottom shell 8, and the extraction solution will also contact the test paper 2 inside the medicine adding port 3. Then wait for the test result.
[0026] As a further improvement of the present utility model, as Figure 3As shown, the horizontal center line of the pin 10 and the horizontal center line of the connecting cylinder 12 are in the same straight line, and the inner diameter of the connecting cylinder 12 is the same as the outer diameter of the pin 10, ensuring that the pin 10 can be inserted into the inside of the connecting cylinder 12.
[0027] As a further improvement of the present utility model, as Figure 1 , Figure 2 and Figure 3 shown, an end cap 6 is spirally connected to the outside of the threaded ring 5. A limiting ring 7 is fixedly connected to the inside of the end cap 6. The limiting ring 7 is made of a rubber ring. A cotton swab 13 is inserted into the inside of the limiting ring 7. When the cotton swab 13 is not in use, the handle of the cotton swab 13 can be limited and fixed through the limiting ring 7, so that the head of the cotton swab 13 will not contact the extraction liquid. At the same time, the test tube 4 can directly store the cotton swab 13, eliminating the need for the staff to prepare a separate container, which is convenient for the staff to use.
[0028] Working process: During use, the extraction liquid is directly placed inside the test tube 4. At the same time, the bottom shell 8 will seal the bottom of the test tube 4, and the extraction liquid will also be stored inside the bottom shell 8. Then, the handle of the cotton swab 13 is passed through the limiting ring 7, and the cotton swab 13 is limited and fixed through the limiting ring 7. Then, the end cap 6 is spirally connected to the threaded ring 5, and at the same time, the head of the cotton swab 13 is immersed in the extraction liquid. After standing for 3 - 5 minutes, the staff pulls the cotton swab 13 along the limiting ring 7 upwards through the handle of the cotton swab 13, separating the head of the cotton swab 13 from the extraction liquid. Then, the staff squeezes the test tube 4 on both sides of the head of the cotton swab 13, and the head of the cotton swab 13 is squeezed through the test tube 4, causing the liquid at the head of the cotton swab 13 to flow into the inside of the bottom shell 8. Then, the staff pinches the first button 9 and the second button 11 with their hands, causing the first button 9 and the second button 11 to drive the corresponding pin 10 and connecting cylinder 12 to squeeze the bottom shell 8. At the same time, the pin 10 will pierce the bottom shell 8 and enter the inside of the connecting cylinder 12. Then, the pin 10 is separated from the connecting cylinder 12. At this time, the extraction liquid inside the bottom shell 8 will flow into the inside of the medicine adding port 3 through the pierced bottom shell 8, and the extraction liquid will also contact the test paper 2 inside the medicine adding port 3. Then, wait for the test result. Through the above method, the transfer steps of the extraction liquid are reduced, which is convenient for the staff to use. Moreover, the extraction liquid directly falls into the inside of the medicine adding port 3 from the test tube 4, reducing the contact time of the extraction liquid with the air and the probability of the extraction liquid being contaminated, improving the accuracy of the detection; when the cotton swab 13 is not in use, the handle of the cotton swab 13 can be limited and fixed through the limiting ring 7, so that the head of the cotton swab 13 will not contact the extraction liquid. At the same time, the test tube 4 can directly store the cotton swab 13, eliminating the need for the staff to prepare a separate container, which is convenient for the staff to use.
