Technical Field

[0001] The utility model relates to the technical field of detection kits, in particular to a detection kit with a liquid injection cavity. Background Art

[0002] Nucleic acid is the carrier of genetic information of living organisms and is an indispensable component of all known life forms. There are two types of nucleic acids, DNA and RNA, which mainly exist in the cell nucleus and exist in a state of being bound to proteins. With the rapid development of molecular biology, the research and analysis of nucleic acids have been continuously promoted and applied in the fields of clinical diagnosis, food safety, environmental testing, agriculture, forestry and animal husbandry. In nucleic acid testing, a test kit is needed. However, when the existing test kit is used, only one opening is opened on the test kit, and then the test liquid is dropped into the upper opening of the test kit. Since the upper opening of the test kit is relatively small, when adding the test liquid, the test liquid will drop outside the test kit, causing the environment outside the test kit to be contaminated. Especially when testing some infectious viruses, the test liquid dripped outside the test kit can easily cause people around to be infected, affecting the health of people around. Therefore, a test kit with an injection cavity is proposed to solve the above problems. Summary of the invention

[0006] Preferably, the liquid injection part includes a reagent tube and a tube cover arranged on the reagent tube, a circular opening is opened on the top surface of the tube cover, and a rubber plug is arranged in the circular opening.

[0007] Preferably, an external thread is provided on the outer wall of the tube cover, and an internal thread is provided on the inner wall of the reagent tube to match the external thread.

[0008] Preferably, the top opening of the liquid injection cavity is wide-mouthed.

[0009] Preferably, an annular rubber ring is provided on the inner wall of the liquid injection cavity, and the top of the annular rubber ring is wide-mouthed.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] The utility model facilitates the preparation of the sample of the test object through the use of the liquid injection piece, thus facilitating the detection of the test object, and the operation is simple and convenient, and the detection efficiency is improved; the coordinated use of the conical hollow needle and the liquid inlet facilitates the dripping of the test object in the reagent tube onto the test paper, and prevents the detection liquid from leaking out of the liquid injection cavity, thereby ensuring the cleanliness of the workbench; the coordinated use of the annular rubber ring facilitates the squeezing of the reagent tube, thereby facilitating the fixing of the reagent tube, and preventing the reagent tube from tipping over, thus facilitating the detection.
