[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] like Figures 1 to 7 As shown, a swab sampling device provided by an embodiment of the present invention includes: a swab stick 2, a tube body 1, a cover body and a liquid squeezing component 3. The swab stick 2 is provided with a sampling portion 201, and the cover body is detachably connected to the tube body 1 to facilitate taking the swab stick 2 out of or putting it into the tube body 1. The liquid squeezing component 3 is arranged on the tube body 1 or the cover body.

[0047] When a swab sampling device of the present invention is used, a sample is collected through the sampling part 201 of the swab stick 2. After sampling is completed, the sample adheres to the sampling part 201. The swab stick 2 is placed in the tube body 1, and the sampling part 201 contacts the sample processing liquid in the tube body 1. The sample on the sampling part 201 is initially released into the eluent by shaking the tube body 1 or stirring the swab stick 2. Then, the swab stick 2 is moved up and down to make the sampling part 201 contact with the liquid squeezing part 3. The two contact and squeeze the sampling part 201 to quickly release the sample attached thereto, thereby squeezing the sample out and retaining it in the tube body 1. This operation can be repeated to achieve the purpose of fully eluting the sample. Compared with the traditional method of eluting the sample, the sample can be squeezed out faster and more fully.

[0048] Specifically, the liquid extrusion component 3 is provided with an elastic deformation portion. When the sampling portion 201 contacts the elastic deformation portion, the elastic deformation portion is elastically deformed. The sampling portion 201 can squeeze out the sample under the action of its elastic deformation force, thereby improving the sample extrusion effect.

[0049] The elastic deformation portion includes a plurality of circumferentially distributed extrusion sheets 301, with gaps between adjacent extrusion sheets 301. The circular arrangement of the plurality of extrusion sheets 301 provides a larger contact area with the extrusion portion 201. Furthermore, the gaps between adjacent extrusion sheets 301 provide a greater elastic deformation space and a greater elastic force. This allows the extrusion sheets 301 to better contact and squeeze the sampling portion 201. Furthermore, the extruded sample can flow out of the gaps, preventing accumulated fluid from being repeatedly absorbed by the sampling portion 201.

[0050] Furthermore, multiple extrusion sheets 301 surround a liquid extrusion channel 303 that contacts the sampling portion 201. The distal end of the liquid extrusion channel 303 is shaped like a circular hole, with a diameter less than or equal to the outer diameter of the sampling portion 201. In other words, the multiple extrusion sheets 301 form a cylindrical shape. This arrangement allows the sampling portion 201 to be surrounded by the multiple extrusion sheets 301 as it passes through the liquid extrusion channel 303, thereby applying force at multiple locations along the circumference, resulting in a better extrusion effect.

[0051] A guide portion 304 is provided at the end of the squeezing channel 303 , wherein the guide portion 304 is configured as a flared structure, which can be configured as a trumpet shape, an arc shape, an inclined surface, etc.

[0052] Furthermore, the diameter of the extrusion channel 303 is configured to taper along the axis of the tube body 1. The taper can be from one end toward the other, for example, forming a conical shape, or it can taper from both ends toward the center, with both ends expanding and the center constricting. This taper allows the sampling portion 201 to be gradually squeezed when the swab rod 2 contacts the extrusion component 3 during movement, thereby improving the extrusion effect and stability.

[0053] The liquid squeezing sheet 301 is provided with a groove or a through hole 302. For example, the through hole 302 can be provided near the root of the liquid squeezing sheet 301. The provision of the groove or the through hole 302 can improve the deformation ability of the liquid squeezing sheet 301 to facilitate better liquid squeezing.

[0054] In one embodiment of the present invention, a swab stick 2 is removably mounted within the tube body 1 and further includes a swab handle comprising a detachable first handle portion 202 and a second handle portion 203. The sampling portion 201 is disposed on the first handle portion 202. It should be noted that the sampling portion 201 functions to absorb the sample, and therefore can be made of any absorbent material, including but not limited to cotton or plastic. During sampling, the first and second handle portions 202, 203 are relatively long, enabling insertion into the human body for sampling, such as gynecological or throat swab sampling. After sampling is complete, the second handle portion 202 can be detached from the first handle portion 201 to shorten the length of the swab stick 2, facilitating subsequent handling. The present invention is designed for both automated and manual handling, depending on the application. Furthermore, in this embodiment, the first handle portion 202 is longer than the tube body 1. Therefore, after detaching from the second handle portion 203, a portion of the first handle portion 202 remains exposed outside the tube body 1, facilitating liquid extrusion.

[0055] In this embodiment, the liquid-dispensing component 3 is configured to be removably mounted on the cover body. In this embodiment, the cover body is configured as a pipe plug 4, which is removably connected to the pipe body 1. The connection between the two is as follows: the liquid-dispensing component 3 is provided with a first mounting portion 30, which is configured as a protrusion or groove. The pipe plug 4 is provided with a groove / protrusion that matches the protrusion or groove of the first mounting portion 30. The two form a first concave-convex connection portion to achieve a snap connection, thereby connecting the first mounting portion 30 to the inner wall of the pipe plug 4. In this embodiment, the first mounting portion 30 is provided with a first protrusion 306, which is arranged around the outer circumference of the liquid-dispensing component 3. The pipe plug 4 is provided with a groove 401, which is arranged around the inner wall of the pipe plug 4. The two are connected by a concave-convex connection to achieve a snap connection.

[0056] Furthermore, a positioning boss 305 is provided on the first mounting portion 30, and an annular recess 402 cooperating with the positioning boss 305 is provided on the pipe plug 4. The positioning boss 305 is provided at one end of the liquid-extruding component 3, and the protruding boss 305 is arranged around the outer surface of the liquid-extruding component 3. The annular recess 402 is recessed around the inner wall of the pipe plug. When the liquid-extruding component 3 and the pipe plug are assembled, the two are positioned by the first concave-convex portion being engaged and the boss and annular recess being matched, and the matching is convenient and stable.

[0057] In this embodiment, the pipe plug 4 is engaged with the inner wall of the pipe body 1 by interference fit. Specifically, the outer wall of the pipe plug 4 is provided with an annular protrusion 403, which is engaged with the inner wall of the pipe body 1 by interference fit.

[0058] In this embodiment, the tube plug 4 is provided with an opening 405 for the swab stick to pass through, and the tube plug 4 is provided with a sealing membrane 404 for sealing the opening 405. The sealing membrane 404 can seal the tube plug 4 to maintain the cleanliness of the inside of the tube body 1, and if the tube body 1 contains a sample processing liquid, it can prevent it from flowing out. It should be noted that the sealing membrane 404 initially seals the opening 405, and the swab stick 2 can pierce the sealing membrane 404 when it is loaded into the tube body 1 to release the sample after the sampling is completed. The puncture method can be to use the swab handle to pierce.

[0059] The structure described above can be used in conjunction with an automated sample processing instrument. After the sampling is completed, the second handle 203 is broken off and the sample is sent to the automated sample processing instrument. It should be noted that the sample processing liquid in the tube body 1 can be sealed in the tube body 1 in advance or added to the tube body 1 later. The adding method can be added by the automated sample processing instrument, and the subsequent sample extrusion and release process can also be completed by the automated sample processing instrument.

[0060] Please refer to Figures 8 to 10 , Figure 8 A schematic structural diagram of a swab sampling device provided in another specific embodiment of the present invention; Figure 9 for Figure 8 Exploded diagram; Figure 10 for Figure 8 Schematic diagram of the main cross-section structure.

[0061] In this embodiment, the cover body is configured as a tube cover 5, and the tube cover 5 is configured to be threadedly connected to the tube body 1. In this embodiment, the structure of the liquid squeezing component 3 and the swab rod 2 is the same as that of the above embodiment, except that the liquid squeezing component 3 is installed to the tube body 1. Specifically, the connection method between the liquid squeezing component 3 and the tube body 1 is similar to that of the above embodiment, and the liquid squeezing component 3 is clamped with the inner wall of the tube body 1 through the second concave-convex connection portion.

[0062] In this embodiment, a dripper 502 is further provided at one end of the tube cover 5. The dripper 502 is provided with a dripping hole 501, which connects the tube cover 5 with the interior of the tube body 1, so that the sample liquid in the tube body 1 can be dripped out for sampling operation.

[0063] In this embodiment, the tube body 1 is further configured as a soft tube body, so that during the spotting operation, the outer wall of the tube body 1 can be squeezed by hand to deform it, thereby facilitating the extrusion of the liquid in the tube body 1 and better completing the spotting.

[0064] In this embodiment, a sealing cover 6 is detachably provided on the dripper 502 . The sealing cover 6 is configured to seal the dripping hole 501 . The sealing cover 6 can prevent the sample liquid in the tube body 1 from flowing out.

[0065] The structure of the swab sampling device provided in the above-mentioned another specific embodiment can be manually spot-sampled. The operation of releasing the sample attached to the swab stick 2 into the sample processing liquid in the tube body 1 is the same as that of the first embodiment. After completing the liquid squeezing operation, the swab stick 2 is taken out, the tube cover 5 is covered, and the outer wall of the tube body 1 is squeezed to perform the spot-sample operation through the dripper 502.
