Description

Technical Field

[0001] The present application belongs to the technical field of medical tools, and specifically relates to a cervical exfoliated cell collector. Background Art

[0002] Cervical exfoliated cells refer to the epithelial cells of the cervix. Clinically, the physiological and pathological changes of the cervix are reflected by examining the cervical exfoliated cells.

[0003] Existing cervical exfoliated cell collectors usually include a cervical brush and a preservation fluid bottle, and the cervical exfoliated cell collection method includes: first, the medical staff aligns the cervical brush with the sampling site and scrapes it to make the cervical exfoliated cells adhere to the brush head of the cervical brush; then, the medical staff places the cervical brush into the preservation fluid bottle to dissolve the cell sample in the preservation fluid, thereby facilitating subsequent testing.

[0004] The inventors found that when collecting cervical exfoliated cells in the above manner, the adhesion strength between the cell sample and the cervical brush varies from person to person; when the adhesion strength between the cell sample and the cervical brush is relatively strong, it is necessary to extend the time for the cervical brush to be placed in the preservation solution bottle to ensure that the cell sample can be fully dissolved in the preservation solution. However, the adhesion strength between the cell sample and the cervical brush cannot be estimated, and the speed at which the cell sample dissolves in the preservation solution cannot be accelerated during actual operation, which results in the technical defects of low collection efficiency and poor collection effect of cervical exfoliated cells.

[0022] In a possible implementation, the cross section of the hose is circular, and the closed end thereof adopts a spherical structure; when the sampling rod is inserted into the hose through the through hole, the brush is suitable for being inserted into the spherical structure.

[0023] In a possible implementation, the insertion end of the sampling rod adopts a tip structure suitable for puncturing the film, and the brush and the tip structure are spaced apart along the axial direction of the sampling rod.

[0039] Please also read Figures 1 to 7 The cervical exfoliated cell collector provided by the present application is now described. The cervical exfoliated cell collector provided by the present application comprises a rubber tube 1, a sampling rod 3 and a clamping structure 5.

[0040] The rubber tube 1 is made of rubber or other deformable materials, and has a tube structure with one end open and the other end closed, and the tube cavity is used to contain the preservation liquid.

[0041] In this embodiment, for the convenience of description, the axial direction of the hose 1 is defined as the up-down direction, and the open end thereof faces upward.

[0042] The upper end of the hose 1 is detachably connected to a cover 2 ; when the cover 2 is connected to the hose 1 , the cover 2 seals the opening of the hose 1 to limit the overflow of the preservation liquid in the hose 1 .

[0043] The cover body 2 has a through hole 21 extending in the up-down direction and suitable for communicating with the inside of the hose 1, and a film 22 suitable for closing the through hole 21 is arranged in the through hole 21; the film 22 can prevent the preservation liquid in the hose 1 from overflowing through the through hole 21.

[0044] The sampling rod 3 is used to pierce the film 22 along the axial direction of the hose 1 and insert into the hose 1, and its insertion end is connected to a brush 4 for adhering cervical exfoliated cells; when sampling, the axial direction of the sampling rod 3 is parallel (or nearly parallel) to the sampling surface to avoid the end of the sampling rod 3 contacting the cell sample.

[0045] The sampling rod 3 has a blocking disk 31 extending radially outward at one end away from the brush 4; when the sampling rod 3 pierces the film 22 and is inserted into the hose 1, the blocking disk 31 is used to abut against the upper side of the cover 2 to limit the downward movement of the sampling rod 3.

[0046] The clamping structure 5 is arranged between the blocking disk 31 and the cover body 2, and is used to connect the blocking disk 31 with the cover body 2 to limit the blocking disk 31 from moving away from the cover body 2 (i.e. upward); and when the blocking disk 31 is connected with the cover body 2 through the clamping structure 5, the blocking disk 31 can rotate relative to the cover body 2 with the sampling rod 3 as the axis.

[0047] In the embodiment of the present application, the sampling rod 3 pierces the film 22 and is inserted into the hose 1, so that the brush 4 can be brought into contact with the preservation solution, thereby achieving the transfer of the cell sample on the brush 4; on this basis, the blocking disk 31 and the cover body 2 are connected through the snap-fit ​​structure 5, so that the hose 1 and the sampling rod 3 can be relatively fixed.

[0048] During the transfer of the cell sample, the operator can pinch the rubber tube 1 with his hands to make the inner wall of the rubber tube 1 contact the brush 4; at the same time, the sampling rod 3 is rotated relative to the rubber tube 1 to speed up the transfer efficiency of the cell sample.

[0049] Compared with the prior art, the cervical exfoliated cell collector provided in this embodiment can effectively improve the collection efficiency of cervical exfoliated cells, avoid the impact caused by cell samples remaining on the cervical brush, and ensure the collection effect of cervical exfoliated cells.

[0050] In some embodiments, Figure 1 and Figure 2As shown, the upper side of the blocking disk 31 is fixedly connected with a rotating rod 32, and the rotating rod 32 is coaxially arranged with the sampling rod 3. In this embodiment, the rotating rod 32 adopts a rod body structure with a hexagonal cross section to facilitate the rotation of the operator. In addition, when the blocking disk 31 is connected to the cover body 2 through the clamping structure 5, the hose 1 is coaxially arranged with the sampling rod 3.

[0051] In some embodiments, Figure 7 As shown, the upper end of the rotating rod 32 has a hand-held rod 33; the hand-held rod 33 adopts a straight axis structure and is coaxially arranged with the rotating rod 32, which plays a role in extending the operation area and facilitating manual holding. In addition, the hand-held rod 33 is connected to the rotating rod 32 through a plurality of connecting rods 34. Specifically, the plurality of connecting rods 34 are distributed at intervals along the circumference of the rotating rod 32, and the upper and lower ends of each connecting rod 34 are respectively connected to the lower end of the hand-held rod 33 and the upper end of the rotating rod 32.

[0052] In some embodiments, Figure 3 and Figure 6 As shown, the clamping structure 5 includes an annular groove 51 and a plurality of inserting rods 52 .

[0053] The annular groove 51 is formed on the upper side of the cover body 2 , and its annular structure is coaxially disposed with the through hole 21 .

[0054] A plurality of insert rods 52 are fixedly connected to the lower side of the blocking disk 31, and are arranged at intervals along the circumference of the blocking disk 31; Figure 7 As shown, in this embodiment, there are four insertion rods 52 , and the four insertion rods 52 are distributed at equal intervals along the circumference of the blocking disk 31 .

[0055] The axial direction of each insertion rod 52 is parallel to the up-down direction so as to be inserted into the annular groove 51 ; and the lower end of each insertion rod 52 has a protrusion 521 made of elastic material suitable for being snapped into the annular groove 51 .

[0056] In some embodiments, Figure 3 and Figure 6 As shown, the outer wall of the hose 1 has an external thread structure 11, and the cover body 2 also includes a threaded sleeve 23, which is integrally connected to the lower side of the cover body 2 and is suitable for being threadedly connected to the external thread structure 11 to achieve a detachable connection between the hose 1 and the cover body 2.

[0057] In some embodiments, Figure 2 As shown, the outer peripheral wall of the hose 1 also has a limiting ring 12 extending radially outward; when the lower side surface of the cover body 2 is connected to the upper end surface of the hose 1, the lower end of the threaded sleeve 23 abuts against the limiting ring 12, so that the operator can observe and judge the connection status of the hose 1 and the cover body 2.

[0058] In some embodiments, Figure 5 As shown, a plurality of anti-skid grooves 231 are arranged at intervals along the circumference of the threaded sleeve 23 on the outer peripheral wall thereof; by providing the anti-skid grooves 231, slipping between the threaded sleeve 23 and human hands can be avoided, thereby improving the stability of the threaded sleeve 23 during use.

[0059] In some embodiments, Figure 1 and Figure 2 As shown, the cross section of the hose 1 is circular, and its closed end adopts a spherical structure; on this basis, when there is preservation liquid inside the hose 1, most of the preservation liquid is at the lower end of the hose 1.

[0060] When the sampling rod 3 is inserted into the hose 1 through the through hole 21, the brush 4 is suitable for being inserted into the spherical structure to ensure that it is completely immersed in the preservation liquid. When the spherical structure is pinched by hand, most of the preservation liquid enters the tube structure on the upper side of the spherical structure; when the hand that pinches the spherical structure is released, the hose 1 returns to its original state, the preservation liquid re-enters the spherical structure, and effectively flushes the surface of the brush 4.

[0061] In some embodiments, Figure 5 As shown, the insertion end of the sampling rod 3 adopts a tip structure suitable for puncturing the film 22, and the brush 4 and the tip structure are spaced apart along the axial direction of the sampling rod 3; that is, there is a distance between the aforementioned tip structure and the brush 4.

[0062] By adopting the above technical solution, when the brush 4 is used for cell sampling and the brush 4 contacts the skin of the sampler, there is a gap between the tip structure and the human skin, thereby avoiding the tip structure contacting the skin and causing pain.

[0063] It should be noted that the aforementioned tip structure only needs to be able to pierce the film 22; in order to avoid the tip structure causing damage to human skin, the tip structure will not be too sharp.

[0064] In some embodiments, Figure 2 As shown, when the sampling rod 3 is inserted into the hose 1 and the sampling rod 3 and the hose 1 are coaxially arranged, there is a gap between the brush 4 and the inner wall of the hose 1; therefore, before the brush 4 is inserted into the hose 1 and contacts with the preservation solution, the brush 4 will not be scratched against the inner wall of the hose 1, thereby avoiding the loss of the cell sample on the brush 4 and ensuring the integrity of the cell sample.

[0065] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
