[0002] A sampling tube is a tube used to collect samples of uniformly distributed substances such as gases and liquids. For example, a nasopharyngeal swab sampling tube is mainly used to collect secretions from the nasopharyngeal region and transport the sample from the sampling point to a testing laboratory for extraction and polymerase chain reaction (PCR) testing. It is applicable to the monitoring and sampling of infectious pathogenic microorganisms, such as various viruses like influenza virus (including common influenza and highly pathogenic avian influenza, etc.), hand, foot and mouth disease virus, as well as mycoplasma and chlamydia. In addition, it can also be used to preserve nasopharyngeal swab samples or arranged samples at specific sites such as necessary cell culture.

[0003] Traditional sampling tubes include a tube body and a tube cap. After sampling with a sampling cotton swab, it is placed in the tube body for subsequent testing. When testing, the tube cap is opened to take out the immersed sample for testing. The problems are that the sampling cotton swab is not fixed in the tube body and is easy to shake, the sampling method is difficult, and it is not convenient for droppable or smearable sampling; it is not easy to insert the sampling cotton swab in place when it is inserted into the inner wall of the tube cap.

[0004] Therefore, a droppable and smearable sampling tube group is designed to solve the above problems. Summary of the Invention

A cover plate is hinged on the top surface of the tube cap. A plug is arranged at the center of the bottom surface of the cover plate. The circumferential side of the tube cap is provided with an external thread for mating connection with the top surface of the tube body. A frustum-shaped guiding groove opening downward is formed on the bottom surface of the tube cap, and a through socket is formed in the frustum-shaped guiding groove; one end of the socket leaking out of the top surface of the tube cap is provided with an extrusion port, and the extrusion port is in mating connection with the plug; the end of the socket opening on the bottom surface of the tube cap is used for inserting the sampling cotton swab after sampling and breaking.

[0007] A groove for easy breaking is arranged around the middle of the sampling cotton swab; the sampling cotton swab is divided into a hand-held part and a sampling part by the groove. A cotton head is arranged at the end of the sampling part; the length of the sampling part is less than the depth inside the tube body.

[0008] Preferably, the tube body is made of white semi-transparent soft plastic material, and scale lines are arranged on the circumferential side of the tube body to facilitate observing the liquid level and calculating the volume of the solution.

[0009] Preferably, two sunken thumb grooves are oppositely arranged on the circumferential side of the tube body, and the thumb grooves facilitate hand holding.

[0010] Preferably, the edge of the extrusion port bulges outward to form a circular ring, and a circular convex ring is arranged outside the plug. The circular ring and the convex ring are cooperatively arranged to enhance sealing and connect the tube cap and the cover plate.

[0011] Preferably, several vertical ribs for clamping the sampling cotton swab are arranged on the inner wall of the extrusion port.

[0012] Preferably, the edge of the cover plate bulges outward to form a convex edge, which facilitates opening the cover plate.

[0013] The beneficial effects of the present utility model are as follows:

[0014] For the droppable and smearable sampling tube group of the present utility model, when the sampling cotton swab is inserted into the inner top wall of the tube cap, the frustum-shaped guiding groove is easy to be inserted in place at one time; when the sampling cotton swab is inserted into the insertion opening and fixed, it is not easy to shake; the sampling method can be extrusion dropping or smear sampling, which is very convenient.
