A general-purpose glass slide container high-efficiency liquid removal device

Abstract

This invention provides a universal, high-efficiency liquid removal device for slide containers, comprising a slide container and a slide lifting frame for carrying slides. Several staggered top columns are arranged at the bottom of the slide container. When the slide lifting frame carrying slides is placed into the slide container, one of two adjacent slides is lifted by the staggered top columns. A liquid collection component is provided at the bottom of the slide container. Drainage components are provided on the staggered top columns. When the staggered top columns lift the slides, the liquid on the slides is guided into the liquid collection component through the drainage components. In this invention, after the slide lifting frame is placed in, one of two adjacent slides is lifted by the staggered top columns, resulting in a staggered arrangement of the slide bottoms. This breaks the continuous adsorption bridge formed by surface tension between adjacent slides, thereby disrupting the adsorption conditions and preventing the dye from being stably adsorbed between the bottoms of adjacent slides, causing the dye to drip rapidly from between the bottoms of the slides.

Description

Technical Field

[0001] This utility model relates to the field of glass slide staining technology, and in particular to a general-purpose glass slide storage device for efficient removal of staining solution. Background Technology

[0002] When staining slides, the slides are first placed one by one on a slide holder. To increase the number of slides that can be placed on the holder, the spacing between adjacent slides is usually small (usually 3-5 mm). Then, the slide holder carrying the slides is placed into the first staining vat containing the staining solution. After soaking for a certain period of time, the slides are removed from the first staining vat. The same method is then used to place the slides into the second staining vat for staining, until the slides have passed through all the staining vats, thus completing the staining process.

[0003] Then, different dyeing vats contain different dye solutions. When a slide is lifted from one vat and placed into the next, because the distance between adjacent slides in the slide holder is relatively short and the bottom height of the slides is the same, the dye solution adheres to the bottom of the adjacent slides due to surface tension. This creates a dripping residue between the bottoms of adjacent slides, which is carried from the previous vat into the next, causing cross-contamination between dye solutions. To address this dripping residue problem, some slide staining machines reduce the speed at which the slide holder is lifted from the vat and transferred to the next, allowing more time for the dripping residue to drip back into the current vat. However, removing the dripping residue in this way still requires a long time to completely drip back into the vat, significantly increasing the time required for slide staining and reducing staining efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a universal, high-efficiency liquid removal device for glass slides.

[0005] The purpose of this utility model is achieved through the following technical solution: a universal high-efficiency liquid removal device for a slide compartment, comprising a slide compartment and a slide lifting frame for carrying the slides. Several staggered top columns are arranged at the bottom of the slide compartment. When the slide lifting frame carrying the slides is placed into the slide compartment, one of two adjacent slides is lifted by the staggered top columns. A liquid collection component is arranged at the bottom of the slide compartment. A drainage component is arranged on the staggered top columns. When the staggered top columns lift the slide, the liquid on the slide is guided into the liquid collection component through the drainage component.

[0006] Preferably, the bottom of the slide compartment is provided with a through groove corresponding to the misaligned top post, the misaligned top post passes through the through groove, and the lower end of the misaligned top post is provided with a connecting hole, the lower end of the misaligned top post is fixedly connected to the slide compartment through the connecting hole.

[0007] Preferably, the drainage component is drainage paper, which covers the outside of the misaligned top column, and the lower end of the drainage paper passes through the through groove at the bottom of the slide compartment and enters the liquid collection component.

[0008] Preferably, the slide holder has a first positioning ramp on each side, and the slide compartment has a second positioning ramp on its inner wall for cooperating with the first positioning ramp.

[0009] Preferably, a gap is left between the through groove and the misaligned top column.

[0010] Preferably, the liquid collection component is fixedly connected to the slide chamber by screws.

[0011] The beneficial effects of this utility model are:

[0012] 1. In this utility model, after the slide holder is placed in, one of the two adjacent slides is lifted by the staggered top column, so that the bottom of the slides presents an alternating arrangement, breaking the continuous adsorption bridge formed by the surface tension of the liquid between the adjacent slides, thereby destroying the adsorption conditions of the liquid, making it impossible for the dye to be stably adsorbed between the bottoms of the two adjacent slides, and causing the dye to drip rapidly from the bottoms of the slides.

[0013] 2. Traditional slow-speed lifting racks rely on the natural dripping of liquid, which is relatively slow; however, this application breaks the continuous adsorption bridge formed by the surface tension of the liquid through the misaligned top column, resulting in a fast dripping speed, allowing the liquid to drip completely within 5-10 seconds. This effectively improves dyeing efficiency while achieving the removal of the liquid.

[0014] 3. In this utility model, a drainage component is provided on the misaligned top column. When the misaligned top column lifts the glass slide, the drainage component contacts the bottom of the glass slide. Through the drainage effect of the drainage component, the dye liquid attached to the bottom of the glass slide is efficiently introduced into the liquid collection component, thereby further improving the liquid removal effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0025] like Figures 1 to 8 As shown, a general-purpose high-efficiency liquid removal device for slides includes a slide compartment 3 and a slide lifting frame 1 for carrying slides 2. Several staggered top columns 5 are arranged at the bottom of the slide compartment 3. When the slide lifting frame 1 carrying the slides 2 is placed into the slide compartment 3, one of two adjacent slides 2 is lifted by the staggered top columns 5. A liquid collection component 4 is arranged at the bottom of the slide compartment 3. A drainage component is arranged on the staggered top columns 5. When the staggered top columns 5 lift the slide 2, the liquid on the slide 2 is guided into the liquid collection component 4 through the drainage component.

[0026] In this invention, when the slide holder 1 is removed from the dyeing vat, it is placed into the slide compartment 3. After the slide holder 1 is placed in, one of the two adjacent slides 2 is lifted by the misaligned top post 5, so that half of the slides 2 are lifted by the misaligned top post 5, thus making the bottom of the slides 2 appear to be arranged in an alternating pattern. Because the bottom of the slides 2 is arranged in an alternating pattern, a height difference is formed between the bottoms of the originally horizontally aligned slides 2, which completely breaks the continuous adsorption bridge formed by the surface tension of the liquid between adjacent slides 2 (i.e., "liquid hanging phenomenon"), thereby destroying the adsorption conditions of the liquid, making it impossible for the dye liquid to be stably adsorbed between the bottoms of the two adjacent slides 2, causing the dye liquid to drip rapidly from the bottoms of the slides 2.

[0027] Traditional slow-speed lifting racks rely on the natural dripping of liquid, which is relatively slow. However, this application breaks the continuous adsorption bridge formed by the surface tension of the liquid through the misaligned top column 5, resulting in a fast dripping speed. The liquid is dripped within 5-10 seconds, which effectively improves the dyeing efficiency while achieving the removal of the liquid.

[0028] In this invention, a drainage component is provided on the misaligned top column 5. When the misaligned top column 5 lifts the glass slide 2, the drainage component contacts the bottom of the glass slide 2. Through the drainage effect of the drainage component, the dye liquid attached to the bottom of the glass slide 2 is efficiently introduced into the liquid collection component 4, thereby further improving the liquid removal effect.

[0029] The bottom of the slide compartment 3 is provided with a through groove corresponding to the misaligned top post 5. The misaligned top post 5 passes through the through groove, and the lower end of the misaligned top post 5 is provided with a connecting hole 6. The lower end of the misaligned top post 5 is fixedly connected to the slide compartment 3 through the connecting hole 6.

[0030] The drainage component is drainage paper 7. For example... Figure 8 As shown, the drainage paper 7 covers the outside of the misaligned top post 5, and the lower end of the drainage paper 7 passes through the through groove at the bottom of the slide chamber 3 and enters the liquid collection component 4. When the misaligned top post 5 lifts the slide 2, the upper end of the drainage paper 7 contacts the bottom of the slide 2, and the liquid (dye solution) adhering to the lower end of the slide 2 is guided into the liquid collection component 4 at the lower end of the slide chamber 3 through the drainage effect of the drainage paper 7. The drainage paper 7 used in this embodiment is prior art.

[0031] A gap is left between the through groove and the offset top column 5. This gap is used to allow the drainage paper 7 to pass through, and also allows liquid dripping onto the bottom of the slide chamber 3 to flow into the liquid collection component 4.

[0032] like Figure 2 and Figure 3 As shown, the slide holder 1 has a first positioning inclined surface 8 on each side, and the slide compartment 3 has a second positioning inclined surface 9 on its inner wall for engaging with the first positioning inclined surface 8. When the slide holder 1 is placed into the slide compartment 3, the first positioning inclined surface 8 on the slide holder 1 contacts the second positioning inclined surface 9 on the inner wall of the slide compartment 3, and the positioning of the slide holder 1 is achieved through the engagement between the first positioning inclined surface 8 and the second positioning inclined surface 9.

[0033] In this embodiment, the liquid collection component 4 is fixedly connected to the glass slide compartment 3 by screws.

[0034] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
