Description

Technical Field

[0001] The utility model relates to a fixing frame, in particular to a glass slide fixing frame for a cell slide making machine. Background Art

[0002] The slide maker, based on the principles of liquid-based cytology and utilizing cytological detection technology, automatically prepares exfoliated cell smears, significantly improving the quality of pathological cytology slides. Based on the principles of liquid-based cytology, it utilizes pneumatic and hydraulic principles to disperse, filter, and transfer collected cell samples. Using biochemical principles, cells collected on the filter membrane are naturally adsorbed onto the glass slide, achieving perfect cell transfer and evenly paving the slide in a single layer for easy staining and diagnosis. Existing slide makers include a sampling mechanism that removes the cell solution from the sample tube and drips it into a sedimentation chamber, where it settles naturally due to gravity onto the adhesive slide, where it is captured. Slide preparation requires that the cells on the slide be evenly distributed and non-overlapping.

[0003] The existing method of fixing the glass slide is to place the glass slide in a receiving groove on the base plate, and then place the sedimentation chamber on the glass slide and fix it so that the bottom end of the sedimentation chamber contacts the upper end surface of the glass slide, so that the sedimentation chamber can achieve the purpose of allowing cells to naturally settle onto the glass slide with adhesion function by gravity; the sedimentation chamber is generally fixed by clamps or bolts, which is cumbersome to operate during fixation. At the same time, since the bottom end of the sedimentation chamber needs to contact the upper end surface of the glass slide, the force of the sedimentation chamber moving downward during fixation is not easy to control, and may even cause damage to the glass slide. Utility Model Content

[0008] Furthermore, the angles between the first inclined surface of the self-locking block and the second inclined surface of the limiting block and the horizontal plane are both less than degrees.

[0009] Furthermore, the elastic element adopts a self-locking spring. When the self-locking block and the limiting plate are in the initial state, the elastic force of the self-locking spring is smaller than the elastic force of the lifting spring.

DETAILED DESCRIPTION

[0028] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0029] See also Figure 1-10 The slide holder for a cell preparation machine described in the present invention comprises a base plate 1, the upper end surface of the base plate 1 is provided with a plurality of transverse grooves 2 along the front-to-back direction, and the upper end surface of the base plate 1 located before and after the transverse grooves 2 is provided with a fixing device of a sedimentation bin 5, the fixing device comprises two limiting plates 3 arranged on the upper end surface of the base plate 1, the lower end surface of each limiting plate 3 is provided with a limiting groove 4, the sedimentation bin 5 comprises a bin body 6, and a fixing plate 7 fixedly arranged at the lower part of the outer surface of the bin body 6, and the outer surface of the fixing plate 7 is symmetrically fixed with a clamping block 8; when in use, the slide 9 is placed in the transverse groove 2, and then the two clamping blocks 8 of the sedimentation bin 5 are entered between the two base plates 1, and then the sedimentation bin 5 is rotated so that the two clamping blocks 8 of the sedimentation bin 5 are both entered into the limiting groove 4, and at the same time, the lower end surface of the bin body 6 of the sedimentation bin 5 is aligned with the slide The glass slide 9 is in contact with the sedimentation chamber 5, thereby achieving the purpose of fixing the sedimentation chamber 5 on the upper end surface of the slide 9 and also achieving the purpose of fixing the slide 9 by the sedimentation chamber 5. Since the upper and lower positions of the sedimentation chamber 5 are limited by the limiting groove 4, the height of the limiting groove 4 is adapted to the distance between the clamping block 8 on the chamber body 6 and the bottom end of the chamber body 6. After the clamping block 8 is inserted into the limiting groove 4, the bottom end of the chamber body 6 is just in contact with the slide 9; when making a slide, the liquid-based cell solution in the test tube 23 of the sample pool 22 is dripped into the chamber body 6 through the sampling needle of the slide making machine (not shown in the figure), that is, the reagent containing tissue cells is placed at the bottom of the chamber body 6, and then it is still, and the cell gravity is used to naturally settle onto the slide 9 with adhesion function and be captured by the slide 9. The slide making requires that the cells on the slide 9 are evenly distributed without overlapping.

[0030] In order to achieve the height adjustment of the limit plate 3 and the purpose of adjusting the height of the bin body 6, in this embodiment, a support block 10 is fixedly provided on the lower end surface of the limit plate 3, and the support block 10 is slidably arranged in the accommodating groove 11 opened on the upper end surface of the base plate 1, and a lifting spring 12 is provided between the lower end surface of the support block 10 and the inner bottom wall of the accommodating groove 11, and the lifting spring 12 drives the support block 10 to always move upward; a side plate 13 is fixedly provided at a position corresponding to the upper end surface of the base plate 1 and the limit plate 3, and two limit blocks 14 are fixedly provided on one side of the side plate 13 close to the limit plate 3, and the two limit blocks 14 are both located above the limit plate 3, and the lifting spring 12 drives the support block 10 to move upward in accordance with each limit plate When the lifting frame 11 is in the state of being lifted up, the lifting frame 11 is in the state of being lifted up, and the lifting frame 11 is in the state of being lifted up.

[0031] When the two self-locking blocks 15 are closed, the upper end surface of the limit plate 3 is in contact with the lower end surface of the two limit blocks 14, and the two self-locking blocks 15 are in contact with each other, so that the upper end surface of the limit plate 3 and the lower end surface of the two limit blocks 14 are in contact with each other. When in use, first restore the initial state, then put the slide 9 into the transverse groove 2, then place the sedimentation bin 5 between the two limit plates 3, and then rotate the sedimentation bin 5 so that the two blocks 8 of the sedimentation bin 5 are both stuck in the corresponding limit grooves 4. At this time, press the sedimentation bin 5 downward so that the sedimentation bin 5 drives the limit plates 3 to move downward through the blocks 8. If there is a gap between the bottom end of the sedimentation bin 5 and the slide 9 at this time, the sedimentation bin 5 will drive the limit plates 3 to move downward by a distance adapted to the gap. , and then the limiting plate 3 drives the two self-locking blocks 15 to move downward, so that a gap appears between the first inclined surfaces 16 and the corresponding second inclined surfaces 17 of the two self-locking blocks 15. At this time, the elastic element drives the two self-locking blocks 15 to move outward, so that the first inclined surfaces 16 of the self-locking blocks 15 are fitted with the second inclined surfaces 17 of the corresponding limiting blocks 14. At this time, the pressure on the sedimentation bin 5 is released, and the position of the sedimentation bin 5 will be locked, thereby ensuring that the bottom end of the sedimentation bin 5 is in contact with the upper end surface of the slide 9.

[0032] In order to better realize the self-locking function of the self-locking block 15, in this embodiment, the angles between the first inclined surface 16 of the self-locking block 15 and the second inclined surface 17 of the limit block 14 and the horizontal plane are both less than 30 degrees; when the sinking bin 5 is pressed downward so that a gap appears between the first inclined surface 16 of the self-locking block 15 and the second inclined surface 17 of the limit block 14, the elastic element will drive the two self-locking blocks 15 to move outward so that the first inclined surface 16 and the second inclined surface 17 are in contact with each other. At this time, the pressing of the sinking bin 5 is released, and the lifting spring 12 has a tendency to push the limit plate 3 upward through the support block 10. However, the angles between the first inclined surface 16 and the second inclined surface 17 and the horizontal plane are both less than 30 degrees. Coupled with the thrust of the elastic element, the lifting spring 12 cannot push the limit plate 3 to move upward, thereby realizing the self-locking of the position of the limit plate 3, and then realizing the self-locking of the position of the sinking bin 5.

[0033] In this embodiment, the elastic element adopts a self-locking spring 18. When the self-locking block 15 and the limit plate 3 are in the initial state, the elastic force of the self-locking spring 18 is less than the elastic force of the lifting spring 12. Therefore, the self-locking spring 18 cannot push the self-locking block 15 to move outward, and thus cannot enable the self-locking block 15 to drive itself and the limit plate 3, and the support block 10 to move downward to compress the lifting spring 12; the stability of the initial state is achieved.

[0034] In this embodiment, adjacent side surfaces of the two self-locking blocks 15 are each provided with an accommodating hole 19 , and both ends of the self-locking spring 18 are respectively located in the corresponding accommodating holes 19 .

[0035] In order to increase the stability of the up and down movement of the limit plate 3, in this embodiment, two sliders are fixedly provided on a side surface of the limit plate 3 close to the side plate 13, and two vertical sliding grooves are provided at positions corresponding to the side plate 13 and the sliders. The limit plate 3 is connected to the side plate 13 in an up and down sliding direction through the sliders and the sliding grooves; when the limit plate 3 moves up and down, the sliders slide in the sliding grooves, thereby increasing the stability of the up and down movement of the limit plate 3.

[0036] In order to increase the stability of the self-locking block 15 sliding left and right, in this embodiment, a guide block is fixedly provided on the lower end surface of the self-locking block 15, and a guide groove 20 is opened in the left and right directions of the upper end surface of the limit plate 3. The self-locking block 15 is slidably connected to the limit plate 3 through the guide block and the guide groove 20; when the self-locking block 15 slides left and right on the limit plate 3, it slides in the guide groove 20 through the guide block, thereby increasing the stability of the movement of the self-locking block 15.

[0037] In this embodiment, a plurality of substrates 1 are fixedly arranged in the front-to-back direction in the main body 21 of the cell slide making machine. A sample pool 22 is provided on the left side of the main body 21 of the cell slide making machine, and a plurality of test tubes 23 containing reagent samples are provided inside the sample pool 22. When making slides, the liquid-based cell solution in the test tubes 23 of the sample pool 22 is dripped into the chamber body 6 through the sampling needle of the slide making machine (not shown in the figure), that is, the reagent containing tissue cells is placed at the bottom of the chamber body 6, and then it is still. Using the gravity of the cells, they naturally settle onto the slide 9 with an adhesion function and are captured by the slide 9. The slide making requires that the cells on the slide 9 are evenly distributed and not overlapped. The upper end surface of the main body 21 is hinged with an organic cover 24.

[0038] When the cam 5 is in the downward direction, the two locking plates 3 are locked in the corresponding grooves 4. At this time, the cam 5 is pressed downward, so that the cam 5 drives the limiting plates 3 to move downward through the locking plates 8. If there is a gap between the bottom end of the cam 5 and the glass slide 9 at this time, the cam 5 will drive the limiting plates 3 to move downward a set distance, thereby causing the limiting plates 3 to drive the two self-locking blocks 15 to move downward, so that there is a gap between the first inclined surface 16 of the two self-locking blocks 15 and the corresponding second inclined surface 17. At this time, the self-locking spring 18 drives the two self-locking blocks 15 to move outward, thereby causing the first inclined surface 16 of the self-locking block 15 to fit the second inclined surface 17 of the corresponding limit block 14. At this time, the pressing of the cam 5 is released, and the position of the cam 5 will be locked, thereby ensuring that the bottom end of the cam 5 is in contact with the upper end surface of the glass slide 9.
