Description

Technical Field

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

[0002] A slide is a glass slide (or quartz slide) used to hold cell samples (or tissue sections) when observing cells under a microscope. It is usually rectangular and has good light transmittance.

[0003] During the observation process, the operator places the cell sample on a glass slide and then places a cover glass on the surface of the cell sample to prevent the objective lens from contacting the cell sample during the observation process, thereby avoiding unexpected situations such as the cell sample being disturbed and the objective lens being contaminated.

[0004] The inventors found that the existing glass slides can only carry a single group of cell samples, while when comparing and observing multiple groups of cell samples of cervical exfoliated cells, multiple glass slides need to be used simultaneously; this requires the operator to repeatedly pick up and put down different glass slides, and to focus on the target sample during each observation, resulting in technical defects such as increased difficulty of observation and reduced observation efficiency; at the same time, the repeated taking and placing of glass slides may cause relative movement between the glass slide and the cover glass, resulting in unexpected situations in which the cell sample detaches from the glass slide and the cell sample is lost.

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] Please also read Figures 1 to 8 The glass slide for cervical exfoliated cells provided by the present application is now described. The glass slide for cervical exfoliated cells provided by the present application comprises a housing 1 , a glass slide body 3 and a rotation drive assembly 4 .

[0042] The housing 1 is hollow inside and has an upward opening, and a cover 2 made of a transparent material and suitable for closing the opening is hingedly connected to the upper side thereof.

[0043] The slide body 3 is suitable for being placed into the housing 1 through the opening of the housing 1 . It has a circular cross-section and a top surface thereof is provided with a plurality of grooves 31 which are spaced apart along the circumference thereof and are used for placing cell samples.

[0044] The rotation driving assembly 4 is disposed in the housing 1 , and is suitable for being arranged in parallel with the slide body 3 in a horizontal direction, that is, the rotation driving assembly 4 is arranged to avoid the opening of the housing 1 .

[0045] When the slide body 3 is in the shell 1 and the bottom surface of the slide body 3 is connected to the inner bottom surface of the shell 1, the slide body 3 is suitable for rotating around its own central axis; and the rotation drive component 4 is transmission-connected to the slide body 3 so that the rotation drive component 4 can drive the slide body 3 to rotate.

[0046] In the embodiment of the present application, the groove 31 can accommodate multiple groups of cell samples at the same time on the slide body 3; when the cell samples are magnified for observation, the housing 1 can be fixed to the observation area, and the cover 2 can be buckled on the upper side of the slide body 3. When the observed cell samples need to be replaced, the operation can be completed by controlling the rotation drive component 4. The process is simple and will not cause damage to the cell samples, effectively improving the efficiency of the observation process.

[0047] Compared with the prior art, the glass slide for cervical exfoliated cells provided in this embodiment can carry multiple groups of cell samples at the same time and eliminate the need for operators to repeatedly take and put them, thereby ensuring the efficiency and stability of the cell sample observation process.

[0048] In some embodiments, Figure 3 and Figure 5 As shown, the rotation driving assembly 4 includes a driving gear 41 and a driven gear ring 42 .

[0049] The driving gear 41 is disposed in the housing 1 , with its axial direction parallel to the up-down direction, and is suitable for rotating around its own central axis.

[0050] In order to facilitate manual operation, the driving gear 41 has a transmission rod 411 which is coaxially arranged therewith, penetrates through the upper side of the housing 1 and extends out.

[0051] The driven gear ring 42 is disposed in the housing 1 and meshes with the driving gear 41 .

[0052] By adopting the above technical solution, when the slide body 3 is in the shell 1 and the bottom surface of the slide body 3 is connected to the inner bottom surface of the shell 1, the outer peripheral wall of the slide body 3 is suitable for connecting with the inner peripheral wall of the driven gear ring 42 to synchronize the rotation of the slide body 3 and the driven gear ring 42.

[0053] In some embodiments, Figure 4 As shown, the outer peripheral wall of the slide body 3 has a plurality of embedding grooves 32 distributed along its circumferential direction, and each embedding groove 32 penetrates the slide body 3 in the up and down direction; accordingly, the inner peripheral wall of the driven gear ring 42 has a plurality of protrusions 421 corresponding to the plurality of embedding grooves 32 one by one.

[0054] By adopting the above technical solution, when the glass slide body 3 is placed in the shell 1 and the bottom surface of the glass slide body 3 is connected to the inner bottom surface of the shell 1, each protrusion 421 is embedded in the corresponding groove 32 along the up and down direction to avoid the accidental rotation of the driven gear ring 42 relative to the glass slide body 3 due to its smooth surface when the driven gear ring 42 and the glass slide body 3 are connected.

[0055] In some embodiments, Figure 5 and Figure 6 As shown, the inner bottom wall of the housing 1 is provided with an annular guide groove 11 , and the lower side surface of each protrusion 421 is provided with a sliding block 422 suitable for being embedded in the guide groove 11 .

[0056] By adopting the above technical solution, on the one hand, the combination of the guide groove 11 and the slider 422 can achieve the fixation of the position of the driven gear ring 42 and the limitation of the rotation direction; on the other hand, since the slide body 3 and the cover body 2 are both made of transparent material, the guide groove 11 can also play the role of marking the edge of the observation area during microscopic observation, so as to avoid efficiency problems caused by the inability of the microscope to focus successfully.

[0057] In some embodiments, Figure 2 and Figure 3 As shown, the extended end of the transmission rod 411 is detachably connected with a rubber cap 412; the rubber cap 412 can increase the contact area between the transmission rod 411 and the human hand, thereby reducing the difficulty of manually driving the transmission rod 411 to rotate.

[0058] In this embodiment, a snap-in groove is provided on the outer peripheral surface of the protruding part of the transmission rod 411, and a block structure capable of being embedded in the snap-in groove is provided on the inner peripheral wall of the rubber cap 412; the snap-in state between the snap-in groove and the block structure can prevent the rubber cap 412 from rotating relative to the transmission rod 411.

[0059] In some embodiments, Figure 7 and Figure 8 As shown, the glass slide for cervical exfoliated cells further includes a lifting structure 5 ; the lifting structure 5 is arranged at the bottom of the shell 1 , and is used to support and push the glass slide body 3 upwards, so that the glass slide body 3 moves to the upper side of the shell 1 .

[0060] In some embodiments, Figure 7 and Figure 8 As shown, the lifting structure 5 includes a receiving groove 51 and a lifting plate 52 .

[0061] The receiving groove 51 is formed on the outer bottom surface of the housing 1 , and the bottom of the groove has a plurality of through holes 511 penetrating to the inner bottom surface of the housing 1 .

[0062] The lifting plate 52 is slidably arranged in the accommodating groove 51 along the up and down directions, and its lower side surface is used for the operator to push, and its upper side surface has a plurality of push rods 521 corresponding to the plurality of through holes 511 one by one; it should be noted that when the shell 1 is placed flat on a horizontal plane, the lifting plate 52 will fall to the opening of the accommodating groove 51 under the action of its own gravity, and at this time, the upper end surface of each push rod 521 is coplanar with the inner bottom surface of the shell 1 to avoid interference with the contact between the slide body 3 and the inner bottom surface of the shell 1.

[0063] Furthermore, in actual use, each push rod 521 is suitable for extending upward through the corresponding through hole 511 to push the glass slide body 3 to move upward, so that the glass slide body 3 is withdrawn from the housing 1.

[0064] In some embodiments, Figure 7 and Figure 8 As shown, the opening of the accommodating groove 51 has a blocking portion 512 extending inwardly; the lower side of the lifting plate 52 has a step groove 522 for connecting with the blocking portion 512; specifically, the step groove 522 is annular and is set to pass through the lower side edge of the lifting plate 52.

[0065] By adopting the above technical solution, when the lower side surface of the lifting plate 52 coincides with the opening of the accommodating groove 51, the bottom of the step groove 522 abuts against the blocking portion 512 to limit the lifting plate 52 from detaching from the accommodating groove 51 from the lower side, thereby improving the structural stability of the jacking structure 5.

[0066] In some embodiments, Figure 1 and Figure 2 As shown, the cover body 2 has a docking portion 21 made of a transparent material and suitable for embedding into the opening of the shell 1; by embedding the docking portion 21 into the opening of the shell 1, the space for the slide body 3 to move upward can be further limited, thereby improving the stability of the slide body 3 in the shell 1.

[0067] In some embodiments, Figures 1 to 3 As shown, the housing 1 adopts an upper and lower split structure, and adjacent splits are connected by a snap-fit ​​structure to facilitate replacement, maintenance and cleaning of internal components.

[0068] 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.
