Thus, other examples of the example embodiments can have different values. It is noted that like references and letters indicate like items in the drawings, and thus, once an item is defined in one drawing, it need not be discussed further in subsequent drawings.

[0028] As shown in Figures 1 to 3 The present application provides a sampling device. An embodiment of the sampling device includes a sampling tube 10, a swab, and a liquid level lifter 20. The sampling tube 10 is configured to hold a sample. The swab is configured to be inserted into the sampling tube 10. The liquid level lifter 20 is configured to be placed into the sampling tube 10 and to fall towards the bottom of the tube.

[0029] The technical scheme of the embodiment one of the sampling device comprises a sampling tube 10, a swab and a liquid level lifting piece 20. The sampling tube 10 is used for containing a sample. When the liquid level of the sample in the interior of the sampling tube 10 is too low and the swab cannot contact the liquid level of the sample when the swab is inserted into the sampling tube 10, the liquid level lifting piece 20 is put into the sampling tube 10. After the liquid level lifting piece 20 falls towards the bottom of the tube of the sampling tube 10, the liquid level lifting piece 20 occupies the interior space of the sampling tube 10, the liquid level of the sample in the sampling tube 10 is raised, and the swab can contact the liquid level of the sample when the swab is inserted into the sampling tube 10 again, so that the swab can successfully sample, the process of extraction or resampling is saved, and the operation is simple. Therefore, the technical scheme of the embodiment one effectively solves the problem of sampling failure caused by the low liquid level in the sampling tube in the related art. The swab can be a sampling needle, a sampling nozzle or a cotton swab.

[0030] As shown in Figures 1 to 3 , the bottom of the tube of the sampling tube 10 is provided with a conical mounting protrusion 11, and the liquid level lifting piece 20 is provided with a conical mounting hole 21 which is inserted and matched with the conical mounting protrusion. The conical mounting protrusion 11 at the bottom of the sampling tube 10 is inserted and matched with the conical mounting hole 21 on the liquid level lifting piece 20, so as to ensure the accurate positioning of the liquid level lifting piece in the sampling tube. This design can avoid the random movement of the liquid level lifting piece in the sampling tube, reduce the sampling failure caused by the uncertain position, and improve the stability and precision of sampling.

[0031] As shown in Figures 1 to 3 , the top surface of the liquid level lifting piece 20 is provided with a standby sampling hole 23, a long and narrow channel is formed between the conical mounting hole 21 and the conical mounting protrusion 11, and the sampling hole is communicated with the tube of the sampling tube 10 through the long and narrow channel. The standby sampling hole 23 provided on the top surface of the liquid level lifting piece 20 is communicated with the interior of the sampling tube through the long and narrow channel formed by the conical mounting protrusion 11, so as to provide an additional sampling path. Even if the liquid level lifting piece sinks to the bottom of the sampling tube, the sampling hole can contact the liquid level of the sample through the long and narrow channel, so as to increase the flexibility of sampling and further improve the success rate of sampling.

[0032] As shown in Figures 1 to 3 , the liquid level lifting piece 20 further comprises an extrusion tube 24 which is connected with the sampling hole 23 in a pluggable manner. The extrusion tube 24 on the liquid level lifting piece 20 is designed in a pluggable manner, so that it can be easily connected or disconnected when needed. This not only simplifies the sampling operation, but also facilitates cleaning and replacement, reduces the risk of cross contamination, improves the hygiene standard and reusability of the device. Since the diameter of the extrusion tube 24 is smaller than the diameter of the sampling tube 10, the liquid level height in the extrusion tube 24 connected with the sampling hole 23 is higher than the liquid level height in the sampling tube 10, so that it is easier to be collected.

[0033] As shown in Figures 1 to 3As shown, the top surface of the extrusion tube 24 is lower than or flush with the top surface of the sampling tube 10. The top surface of the extrusion tube 24 is designed to be lower than or flush with the top surface of the sampling tube 10, which ensures that the extrusion tube does not hinder the insertion of the sampler during sampling, nor does it cause the sample to spill during the sampling process, ensuring the smooth progress of sampling and the integrity of the sample.

[0034] As shown, Figures 1 to 3 The outer wall of the conical mounting protrusion 11 is provided with a plurality of positioning convexities 12, which are arranged along the axis of the sampling tube 10. The inner wall of the conical mounting hole 21 is provided with a positioning ring groove 22, which can be selectively slid onto at least one of the plurality of positioning convexities 12 along the axis of the sampling tube 10. The plurality of positioning convexities 12 on the conical mounting protrusion 11 cooperate with the positioning ring groove 22 on the liquid level lifter 20 to provide multiple positioning options for the liquid level lifter in the sampling tube. This design can flexibly adjust the position of the liquid level lifter according to the sample volume and sampling requirements, ensuring the height of the sampling liquid level, thereby improving the success rate of sampling and the quality of the sample.

[0035] As shown, Figures 1 to 3 The positioning convexity 12 is a flexible member. The positioning convexity 12 is made of flexible material, so that the positioning ring groove 22 can easily slide into the positioning convexity, and at the same time can slightly deform under pressure to enhance the stability of positioning. This design reduces the difficulty of operation, reduces the risk of damage to the sampling device during use, and improves the durability and user-friendliness of the device.

[0036] As shown, Figures 1 to 3 The liquid level lifter 20 is a cube 25. The cube is more easily positioned in the sampling tube. This design ensures that the position of the liquid level lifter at the bottom of the sampling tube is fixed, improving the accuracy and efficiency of sampling.

[0037] As shown, Figure 1 and Figure 2 The sampling device also includes a sampling cover 30, which is openably and closably provided at the mouth of the sampling tube 10. The sampling device is equipped with a sampling cover 30, which is openably and closably provided at the mouth of the sampling tube 10, which not only prevents contamination and evaporation of the sample during transportation and storage, but also ensures that the sampling operation is carried out in a closed environment, improving the safety of sampling and the preservation quality of the sample. The above-mentioned sampling tube is preferably a blood sampling tube.

[0038] In this application, the difference between the second embodiment of the sampling device and the first embodiment of the sampling device is the shape of the liquid level lifter 20. In the second embodiment of the sampling device, as shown, Figure 1 , Figure 2 and Figure 4As shown, the liquid level lifter 20 is a sphere 26. The sphere 26 of the liquid level lifter 20 is shaped so that it can freely roll inside the sampling tube, adapting to sampling tubes of different shapes and sizes. This design increases the versatility of the sampling device, making it suitable for a variety of sampling tubes, improving the adaptability and range of use of the device.

[0039] The diameter of the sphere of the second embodiment and the side length of the cube of the first embodiment are slightly smaller than the inner diameter of the sampling tube 10, so that the cube and the sphere can be put into the sampling tube. The material of the cube and the sphere is polypropylene (PP), which can prevent the detection sample from being contaminated and causing result deviation. The above-mentioned material is anti-pollution, easy to obtain, and convenient for mass production, and small in size.
