Description

Technical Field

[0001] The utility model relates to the field of immunohistochemistry experimental equipment, in particular to a drying plate used for immunohistochemistry. Background Art

[0002] During the immunohistochemistry process, the slides containing specimens need to be sealed. The experimenter uses neutral gum to seal the slides, and then places the slides uniformly on a drying board and air-dries them naturally. However, the natural air-drying speed is slow and the effect is poor. The neutral gum in the slides will overflow from the slides and make the slides adhere to the drying board, which is inconvenient for the experimenter to take out, read and archive the slides. Chinese patent CN 218495672 U slide drying instrument discloses a slide drying board placed on a top plate, with a fan and ventilation holes at the bottom of the top plate, through which air is blown to the slides to speed up the drying speed. However, since the wind blows from the bottom to the drying board, the air flow can only flow out from the four sides of the drying board, and if the fan wind speed is too high, the drying board is easy to shake or blow off. Therefore, the drying effect is not good.

[0003] In addition, the existing film drying rack is a common horizontal plate, which is not conducive to the experimenters to take out and read the films. Summary of the Invention

[0004] The purpose of the present invention is to provide a drying plate for immunohistochemistry, which solves the shortcomings of the existing drying plates introduced in the above background technology.

[0005] In order to achieve the purpose of this utility model, the technical solutions are as follows:

[0006] A drying plate for immunohistochemistry comprises two plate bodies which are rotatably connected. A plurality of placement slots are provided on the top of each plate body, wherein a partition is provided between two adjacent placement slots; and a plurality of ventilation slots are provided on the partition.

[0007] Furthermore, the ventilation slot is arranged in a direction perpendicular to the placement slot at 90 degrees; the depth of the ventilation slot is less than or equal to the depth of the placement slot.

[0008] Furthermore, the width of the barrier portion is greater than or equal to the width of the placement groove.

[0009] Furthermore, a buckle opening is provided at one end of each placement slot.

[0010] Furthermore, the positions of the cleat openings on the two plates are mirror images.

[0011] Furthermore, the two plates are respectively provided with drainage grooves; the drainage grooves are connected to the other end of each placement groove, that is, the other end opposite to the buckle opening.

[0012] Furthermore, at the bottom of the drying board, there are cavity grooves on all four edges, and a support frame is rotatably connected in the cavity groove; the cavity groove and the support frame are arranged at the bottom of each plate body, located on the other side opposite to the rotational connection of the two plate bodies.

[0013] Based on the above-mentioned drying plate, a plurality of protrusions are provided on the bottom of each placement groove.

[0014] Compared with the prior art, the present invention has the following significant advantages:

[0015] 1. A partition is provided between two adjacent placement slots; the partition is provided with a number of ventilation slots, which facilitates the flow of air from the ventilation slots into the side walls of the slide and cover glass, thereby accelerating the drying of the added neutral gum;

[0016] 2. By providing protrusions at the bottom of the placement groove, the slide only contacts a few protrusions instead of the entire bottom surface of the placement groove, thus avoiding contamination caused by repeated use of the drying plate;

[0017] 3. The drying plate is designed to consist of two plates that are rotatably connected. A drainage trough is located at the end opposite the buckle opening. Cavity grooves and rotatably connected support brackets are provided on all four edges of the bottom of the drying plate. When all the support brackets are opened, the two plates will tilt toward the rotational connection, causing the bottom of the placement trough to be off-plane. This allows excess neutral gum on the slide to flow into the drainage trough, helping to remove residual reagents on the slide. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0023] like Figure 1-3 As shown, a drying plate for immunohistochemistry comprises two plates 1, which are rotatably connected. Each plate 1 is provided with a plurality of placement slots 2 at the top, within which slides are placed. Preferably, the placement slots 2 are rectangular slots, shaped to correspond to slides, to facilitate accommodating the slides. Each placement slot is provided with a clip opening 22 at one end. The clip opening 22 facilitates the removal of slides placed in the placement slots from the drying plate.

[0024] Preferably, a plurality of protrusions 21 are provided on the bottom of each placement groove. Six protrusions 21 are provided on the bottom of the placement groove 2. Preferably, three of the protrusions 21 are distributed at one end of the bottom of the placement groove, and the other three protrusions 21 are distributed at the other end of the bottom of the placement groove 2. The three protrusions 21 are triangular. The protrusions 21 can prevent the glass slides from sticking to the drying board due to the dripping of reagents, which is inconvenient for the experimenter to take and place. In addition, since the glass slides only contact a few protrusions instead of the entire bottom surface of the placement groove 2, it can avoid contamination that may be caused by repeated use of the drying board.

[0025] On both plates, there are partitions 3 separating adjacent placement slots 2. The width of the partitions 3 is greater than or equal to the width of the placement slots 2, and the partitions 3 are provided with a plurality of ventilation slots 31. The ventilation slots 31 are arranged in a direction perpendicular to the placement slots 2 at 90 degrees. The depth of the ventilation slots 31 is less than or equal to the depth of the placement slots 2. The ventilation slots 31 facilitate air flow from the ventilation slots 31 into the side walls of the slide and the cover glass, thereby accelerating the drying of the neutral gum. Furthermore, the location area where the ventilation slots 31 are arranged does not exceed the length direction of the placement slots 2.

[0026] In this embodiment, the locations of the snap openings 22 on the two plates are mirror images, that is, the snap openings 22 on the two plates 1 are located on opposite sides of the rotational connection between the two plates 1. Drainage grooves 32 are also provided on each plate. These grooves 32 are connected to the other end of each placement slot 2, i.e., the end opposite the snap opening 22. This facilitates the removal of residual reagents from the slide after the reagents flow toward the end opposite the snap opening and converge in the drainage grooves, reducing the possibility of reagent contamination and ensuring the quality of subsequent experimental images.

[0027] A label attaching area is provided at the top of the placement slot 2. During use, a label can be set on the label attaching area to distinguish the placement slot 2. Of course, the slides can also be marked and distinguished, making it easier for experimenters to clearly identify the type of slide or the type of substance carried by the slide.

[0028] At the bottom of the drying plate, there are cavity grooves 4 on all four edges, and a support frame 5 is rotatably connected in the cavity groove 4. The cavity groove 4 and the support frame 5 are arranged at the bottom of each plate body 1, which is located on the other side opposite to the rotation connection of the two plate bodies.

[0029] During use, the experimenter places the slide into the placement groove 2 in sequence through the buckle opening 22, seals the slide, drips neutral gum and coverslips it. If the neutral gum overflows, the support frame 5 at the bottom of the drying plate is opened. Since the connection between the two plates is a rotation connection, after the four support frames 5 are opened, the two plates 1 will form an inclination toward the rotation connection, causing the bottom of the placement groove 2 to be not on the horizontal plane, making it easier for the extra neutral gum on the slide to flow into the drainage groove, helping to remove residual reagents. At the same time, the experimenter can use a hot air blowing device such as a hair dryer to blow air on the top surface of the drying plate. The air blows from the ventilation slot 31 to the bonding point between the slide and the cover glass, accelerating the air drying of the neutral gum. After the liquid on the slide is dry, the experimenter can put away one of the support frames 5 on each plate, forming an inclined placement of the entire drying plate relative to the operating table, so that the experimenter can read and archive the slides.
