Description

Technical Field

[0001] This utility model relates to the field of microscope slide technology, and more specifically, to a microscope slide for biological samples. Background Technology

[0002] Traditional biological sample slides typically consist of a set of glass slides and a set of coverslips. The biological sample is immersed in the cavity between the coverslip and the glass slide. When it is necessary to observe or compare multiple sets of biological samples simultaneously, in order to improve the convenience of biological sample observation, some biological sample slides have multiple sets of glass slides and coverslips on a set of base plates to hold biological samples of different volumes.

[0003] In existing technologies, because the coverslip rests on the slide by its own weight, the liquid wetting the biological sample is prone to evaporate along the gap between the slide frame and the coverslip frame, making it impossible to preserve the biological sample slide for a long time. Therefore, when observing multiple sets of samples on the substrate, some biological samples are easily affected by liquid evaporation, thus affecting the observation results. Utility Model Content

[0004] The purpose of this invention is to provide a novel biological sample slide to solve the problems mentioned in the background art.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A novel biological sample slide includes a carrier plate and a base plate connected to the bottom of the carrier plate by screws. Multiple sample glass structures are mounted on the base plate located within the cavity of the carrier plate. Each sample glass structure includes a slide assembly and a coverslip assembly covering the slide assembly. A chamber for containing biological samples is sealed between the slide assembly and the coverslip assembly. Each slide assembly includes a slide frame and a slide glass disposed on the slide frame. Each coverslip assembly includes a coverslip frame and a coverslip glass disposed on the coverslip frame. A sealing groove is provided on the stepped surface of the slide frame. A sealing protrusion that mates with the sealing groove is provided below the coverslip frame. Notches for placing and removing coverslip assemblies are provided on both sides of the slide frame. Magnets are embedded in the surface of the slide frame at the notches. Wings that mate with the magnets are provided on both sides of the coverslip frame.

[0007] Furthermore, a silicone sealing gasket is provided in the sealing groove to mate with the sealing protrusion.

[0008] Furthermore, multiple magnetic positioning posts are provided on the surface of the base plate located in the inner cavity of the carrier plate; the magnetic positioning posts cooperate with the positioning holes provided on the glass slide frame.

[0009] Furthermore, multiple spacers for isolating the sample glass structure are provided on the surface of the base plate located in the inner cavity of the carrier plate.

[0010] Furthermore, multiple loading and unloading ports for loading and unloading glass slide assemblies are provided on both the upper and lower sides of the inner cavity of the carrier plate.

[0011] The beneficial effects of this utility model are as follows: Based on the prior art, this utility model provides notches on both sides of the slide frame for placing and removing coverslip assemblies. Magnets are embedded in the plate surface of the slide frame at the notches, and wing plates that cooperate with the magnets are provided on both sides of the coverslip frame. The magnets cause the slide assembly and the coverslip assembly to be tightly attracted together, achieving a chamber sealing effect. To make the sealing effect more significant, this utility model also provides a silicone sealing gasket in the sealing groove of the slide frame. During the process of the slide assembly and the coverslip assembly being tightly attracted together, the sealing protrusion of the coverslip frame comes into contact with the silicone sealing gasket. The elastic deformation of the silicone sealing gasket produces a higher sealing effect, further improving the overall sealing performance, allowing biological sample slides to be preserved for a long time and preventing sample solution evaporation.

Three sample glass structures of different capacities are mounted on the base plate located within the cavity of the carrier plate 1. Each sample glass structure includes a slide assembly and a coverslip assembly covering the slide assembly. A chamber 16 for accommodating biological samples is sealed between the slide assembly and the coverslip assembly. The slide assembly includes a slide frame 2 and a slide glass 14 disposed on the slide frame. The coverslip assembly... The assembly includes a cover glass frame 3 and a cover glass 13 disposed on the cover glass frame; a sealing groove 12 is provided on the stepped surface of the cover glass frame, and a sealing protrusion that cooperates with the sealing groove is provided on the bottom of the cover glass frame 3; notches 10 for taking out and placing the cover glass assembly are opened on both sides of the cover glass frame 2; magnets 9 are embedded on the plate surface of the cover glass frame located at the notches; and wing plates 8 that cooperate with the magnets are provided on both sides of the cover glass frame 3; this embodiment achieves the sealing between the cover glass assembly and the cover glass assembly through the magnetic attraction effect. Example

[0022] Based on Example 1, this embodiment provides a silicone sealing gasket 11 in the sealing groove 12 to cooperate with the sealing protrusion. This allows the sealing protrusion of the cover glass frame to contact the silicone sealing gasket during the tight adhesion of the slide assembly and the cover glass assembly, resulting in a higher sealing effect through the elastic deformation of the silicone sealing gasket. Example

[0023] Based on Embodiment 1, in order to achieve the effect of fixing the slide assembly on the base plate, eight magnetic positioning posts 6 are embedded on the surface of the base plate 17 located in the inner cavity of the carrier plate.
