[0030] Embodiment 1:

[0031] As Figures 1 - 3 shown, the present utility model provides a cell sampler 1 for cervical cancer detection, including: a sampling tube 10, a sampling rod 20 and a sampling brush 30. A sampling channel 11 that is open axially is provided in the sampling tube 10. The sampling rod 20 is movably and rotatably provided in the sampling channel 11. The sampling brush 30 is connected to the sampling rod 20, and the sampling brush 30 can be selectively received in the sampling channel 11.

[0032] In some embodiments, a sampling channel 11 is provided in the sampling tube 10. The two axial ends of the sampling tube 10 are respectively provided with a first open end and a second open end. The first open end and the second open end are respectively communicated with the sampling channel 11. The sampling rod 20 is movably and rotatably provided in the sampling channel 11. One end of the sampling rod 20 is connected with a sampling brush 30. The sampling rod 20 moves axially to selectively allow the sampling brush 30 to be received in the sampling channel 11 through the first open end. The other end of the sampling rod 20 passes through the second open end and extends outside the sampling channel 11.

[0033] It can be understood that when a doctor takes a cervical cancer sample from a patient, the doctor can first insert the sampling tube 10 into the patient's vagina. Subsequently, the doctor can push the sampling brush 30 towards the first open end to move the sampling brush 30 outside the sampling channel 11. At this time, the doctor can rotate the sampling rod 20 to rotate the sampling brush 30, and the sampling brush 30 rotates to take a sample from the cervix. After the sampling brush 30 finishes sampling, the doctor can pull back the sampling rod 20 to receive the sampling brush 30 in the sampling channel 11, and finally take out the sampling tube 10.

[0034] It should be noted that during the above sampling process, the sampling rod 20 can rotate relative to the sampling channel 11, so that the sampling brush 30 can rotate relative to the sampling channel 11, and further enable the sampling brush 30 to collect cell samples on the cervical surface more conveniently and comprehensively. At the same time, during the sampling process, the sampling rod 20 will not contact the inner wall of the vagina, thus avoiding causing discomfort to the patient during sampling (when using a traditional sampling brush for sampling, the rod part of the sampling brush will contact the inner wall of the vagina in a stirring manner, resulting in discomfort to the patient), improving the comfort of the patient during sampling. At the same time, after sampling is completed, the sampling rod 20 moves and the sampling brush 30 is received in the sampling channel 11, avoiding contact with the inner wall of the vagina when the sampling brush 30 is taken out, thus preventing the sample from falling or the sampling brush 30 from sticking to the tissue of the inner wall of the vagina, and further making the taken cervical tissue sample more accurate and improving the accuracy of the test results.

[0035] According to the cervical cancer detection cell sampler 1 of the present utility model, the sampling rod 20 is movably and rotatably arranged in the sampling channel 11 of the sampling tube 10, and the sampling rod 20 moves to selectively receive the sampling brush 30 in the sampling channel 11, avoiding contact between the sampling brush 30 and the inner wall of the vagina when the sampling is completed and the sampling brush 30 is retrieved, thus making the taken cervical tissue sample more accurate, and further making the test result more accurate. At the same time, through the above arrangement, contact between the sampling rod 20 and the inner wall of the vagina during sampling can be avoided, improving the comfort of the patient during sampling.

[0036] Embodiment 2:

[0037] Based on Embodiment 1, the sampler 1 of this embodiment further includes: a bracket 40, the bracket 40 is connected to the sampling tube 10, the bracket 40 is arranged in the sampling channel 11, and the bracket 40 is provided with a first rotating part; a second rotating part is movably sleeved on the outer periphery of the sampling rod 20, and the first rotating part and the second rotating part are rotatably matched.

[0038] In some embodiments, the bracket 40 is arranged in the sampling channel 11 and connected to the inner wall of the sampling channel 11. A second rotating part is sleeved on the outer periphery of the sampling brush 30, and the second rotating part can move axially relative to the sampling brush 30, and the second rotating part and the second rotating part are rotatably matched. Thus, the sampling rod 20 moves axially relative to the second rotating part to realize the axial movement of the sampling brush 30 relative to the sampling tube 10, so as to realize the sampling brush 30 being received in the sampling channel 11 or the sampling brush 30 moving out of the sampling channel 11. The second rotating part rotates relative to the first rotating part to realize the rotation of the sampling rod 20 relative to the sampling tube 10, and further realize the rotation of the sampling brush 30 relative to the sampling tube 10, so that the sampling brush 30 can comprehensively collect cell samples on the cervical surface.

[0039] Embodiment 3:

[0040] Based on Embodiment 2, in this embodiment, a ball head groove 41 is provided on the bracket 40. The ball head groove 41 is configured as a first rotating part, and a ball head 221 is movably sleeved on the outer periphery of the sampling tube 10. The ball head 221 is configured as a second rotating part. It can be understood that the ball head 221 can move relative to the sampling rod 20, and the sampling rod 20 moves relative to the ball head 221 to make the sampling brush 30 move relative to the sampling tube 10, so as to realize that the sampling brush 30 is received in the sampling channel 11 or the sampling brush 30 moves outside the sampling channel 11. The ball head 221 is rotatably engaged with the ball head groove 41, and the ball head 221 rotates to drive the sampling rod 20 to rotate, and the sampling rod 20 rotates to realize the rotation of the sampling brush 30 relative to the sampling tube 10.

[0041] It is worth noting that the rotatable cooperation between the ball head 221 and the ball head groove 41 enables the ball head 221 to have a high degree of rotational freedom relative to the ball head groove 41, thereby enabling the sampling rod 20 to have a high degree of rotational freedom relative to the sampling channel 11, and further enabling the sampling brush 30 to have a high degree of rotational freedom, improving the comprehensiveness of the sampling brush 30 in collecting cell samples on the cervical surface.

[0042] According to some embodiments of the present invention, the sampling rod 20 is further provided with a first limiting boss 222 and a second limiting boss 223 protruding from the outer peripheral wall of the sampling rod 20. The first limiting boss 222 and the second limiting boss 223 are spaced apart from each other in the axial direction, and the ball head 221 is movably disposed between the first limiting boss 222 and the second limiting boss 223.

[0043] In some embodiments, the first limiting boss 222 and the second limiting boss 223 respectively protrude from the outer peripheral wall of the sampling rod 20. The first limiting boss 222 and the second limiting boss 223 are spaced apart in the axial direction, and the ball head 221 is disposed between the first limiting boss 222 and the second limiting boss 223. Thus, the first limiting boss 222 and the second limiting boss 223 can limit the movement of the ball head 221 in the axial direction, prevent the ball head 221 from sliding off the sampling rod 20 in the axial direction, improve the cooperation stability between the ball head 221 and the sampling rod 20, and thus improve the working stability of the sampler 1.

[0044] At the same time, the first limiting boss 222 and the second limiting boss 223 define the maximum extension range of the sampling rod 20 in the sampling tube 10, prevent the sampling rod 20 from penetrating too deeply or coming out of the sampling tube 10, and ensure the safety and effectiveness of the sampling process.

[0045] Embodiment 4:

[0046] Based on Embodiment 3, the sampling rod 20 in this embodiment includes: a first rod portion 21 and a second rod portion 22. One end of the first rod portion 21 is connected to the sampling brush 30, and the second rod portion 22 is detachably connected to the other end of the first rod portion 21. A first limiting boss 222 and a second limiting boss 223 are provided on the second rod portion 22.

[0047] In some embodiments, the first rod portion 21 and the second rod portion 22 are detachably connected axially. The first rod portion 21 and the second rod portion 22 can be snap-connected, thread-connected, or fixed by fasteners, etc., and no limitation is made here.

[0048] The first rod portion 21 is connected to the sampling brush 30, and the second rod portion 22 cooperates with the ball head 221. Thus, when the sampling is completed and sent to the laboratory for inspection, the inspector can separate the first rod portion 21 from the second rod portion 22. The volume of the first rod portion 21 and the sampling brush 30 is smaller than the volume of the sampler 1. That is, the first rod portion 21 and the sampling brush 30 can be more conveniently placed in the detection vessel, thus facilitating the progress of laboratory inspection work.

[0049] At the same time, the first rod portion 21 and the second rod portion 22 are detachably connected, and the first rod portion 21 is directly connected to the sampling brush 30, ensuring the stable assembly of the sampling tool and the effective transfer of the sample, and facilitating the replacement, cleaning, or disinfection of the sampling brush 30. At the same time, it is more conducive to the maintenance, replacement of parts, or deep cleaning of the sampler 1, etc., increasing the long-term use efficiency and hygiene standards of the equipment.

[0050] Embodiment 5:

[0051] Based on Embodiment 1, the sampler 1 in this embodiment further includes: a first sealing plug 51. The first sealing plug 51 is detachably connected to the sampling tube 10 and is arranged at one end close to the sampling brush 30.

[0052] It can be understood that the first sealing plug 51 is detachably fitted with one end of the sampling tube 10 close to the sampling brush 30. The first sealing plug 51 can be thread-connected, snap-connected, or fixed by fasteners to the sampling brush 30, and no limitation is made here. After the sampling is completed, the first sealing plug 51 cooperates with the sampling tube 10 to seal the sampling brush 30 in the sampling channel 11, avoiding the leakage of the sample collected by the sampling brush 30, and can prevent the collected sample from contacting the external environment (bacteria, germs, etc. in the air), improving the inspection accuracy of the sample.

[0053] According to some embodiments of the present utility model, the sampler 1 further includes: a second sealing plug 52, which is movably sleeved on the outer periphery of the sampling rod 20, the second sealing plug 52 is detachably connected to the sampling tube 10, and the second sealing plug 52 is arranged at an end far from the sampling brush 30. It can be understood that the second sealing plug 52 and the first sealing plug 51 cooperate together to seal the sampling channel 11, so that the sealing performance of the sampling channel 11 is better.

[0054] It is worth noting that during sampling, first remove the first sealing plug 51 and separate the second sealing plug 52 from the sampling tube 10, then insert the sampling tube 10 into the vagina, and finally the doctor can control the sampling rod 20 to use the sampling brush 30 to sample the cervix.

[0055] According to some embodiments of the present utility model, a limiting convex block 224 is provided at one end of the sampling rod 20 far from the sampling brush 30, a limiting groove is provided at one end of the second sealing plug 52 facing the limiting convex block 224, and the limiting convex block 224 can be selectively in interference fit with the limiting groove. It can be understood that during sampling, the doctor can make the limiting convex block 224 in interference fit with the limiting groove, so that the second sealing plug 52 is fixedly connected to the sampling rod 20. At this time, the doctor can hold the second sealing plug 52 to control the sampling rod 20. Compared with the doctor directly holding the sampling rod 20, the contact area between the doctor's hand and the second sealing plug 52 is larger, so that the doctor can control the sampling rod 20 more stably, improving the control convenience and stability of the sampler 1.

[0056] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit. Although the present utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present utility model.
