Abstract
Description
Technical Field
[0001] This application relates to the field of cell culture, and more particularly to a porous cell culture plate. Background Technology
[0002] Cell culture refers to the process of simulating the in vivo growth environment by placing cells collected from in vivo tissues under sterile conditions with specific nutrients, temperature, and pH to allow them to grow and multiply, in order to observe the morphology, structure, life activities, and changes of living cells. It plays an important role in research in cell biology, genetics, immunology, and other fields. Cell culture plates are required for cell culture.
[0003] Existing cell culture plates are prone to slipping during stacking due to movement or contact, which can contaminate cells during culture, increase experimental costs, and affect experimental results. Utility Model Content
[0004] To improve the structural stability of cell culture plates during stacking, this application provides a porous cell culture plate.
[0005] The multi-well cell culture plate provided in this application adopts the following technical solution:
[0006] A porous cell culture plate includes a base plate and a cover plate. A boss is formed on the top wall of the base plate, and multiple culture tanks are formed in the boss and the base plate. The cover plate is placed on the boss. A first magnetic element is embedded on the top wall of the base plate outside the boss, and a second magnetic element is embedded on the bottom wall of the cover plate. The first magnetic element and the second magnetic element attract each other. A groove is formed on the bottom wall of the base plate, and a raised strip is fixedly provided on the top wall of the cover plate. In two cell culture plates stacked one on top of the other, the raised strip on the lower cover plate is inserted into the groove on the upper base plate.
[0007] By adopting the above technical solution, the mutual attraction between the first magnetic component and the second magnetic component increases the adsorption force between the cover plate and the bottom plate, making the cover plate and the bottom plate fit tightly together and avoiding contamination problems during cell culture. At the same time, the protrusion and groove form an interlocking structure, which minimizes the risk of slippage or tilting when the upper and lower culture plates are stacked, further improving the stability of the upper and lower stacking structure of the porous cell culture plate.
[0008] Preferably, the bottom wall of the base plate is provided with anti-slip pads.
[0009] By adopting the above technical solution, the bottom plate increases the friction between the bottom plate and the top wall of the lower porous cell culture plate through anti-slip pads to stabilize the stacked structure, prevent it from slipping due to position movement or contact, ensure the stability and safety of the cell culture process, and reduce the risk of contamination.
[0010] Preferably, a limiting groove is formed on the bottom wall of the anti-slip washer, and in the two stacked cell culture plates, the protrusion on the lower cover plate is inserted into the limiting groove of the anti-slip washer at the bottom of the upper base plate.
[0011] By adopting the above technical solution, a limiting groove is opened on the bottom wall of the anti-slip pad, so that the cell culture plates stacked one on top of the other can be restricted from relative movement through the cooperation of the limiting groove and the protrusion, which makes the multi-well cell culture plates more stable when stacked.
[0012] Preferably, the anti-slip pad has a limiting part formed on each of the opposite side walls of the limiting groove, and the middle part of the two limiting parts protrudes in the direction of mutual approach. When the protrusion is inserted into the limiting groove, the ends of the two limiting parts that are close to each other abut against the opposite side walls of the protrusion.
[0013] By adopting the above technical solution, the middle parts of the two limiting parts protrude towards each other, which can limit the insertion position of the protrusion. At the same time, the limiting parts reduce the contact area between the anti-slip washer and the protrusion, thereby reducing the friction between the anti-slip washer and the protrusion, making it easier for the protrusion to be smoothly inserted into the limiting groove and improving the operating efficiency.
[0014] Preferably, the width of the limiting part gradually decreases from its center toward its upper and lower sides.
[0015] By adopting the above technical solution, the width of the limiting part gradually decreases from the middle to the upper and lower sides, making the limiting part more stable during the insertion process, further reducing the risk of slippage when the cell culture plate is stacked, and thus improving the safety and service life of the porous cell culture plate.
[0016] Preferably, the limiting portion of the anti-slip washer is coated with a lubricating coating.
[0017] By adopting the above technical solution, a lubricating coating is applied to the limiting part of the anti-slip washer, which reduces friction and facilitates the insertion or removal of the protrusion into the limiting groove, thereby improving work efficiency.
[0018] Preferably, both the boss and the cover plate have rounded corners at one corner.
[0019] By adopting the above technical solution, a rounded corner is formed at one corner of the boss and the cover plate, so that the boss and the cover plate can fit together smoothly, making it easier for workers to install.
[0020] Preferably, anti-slip textures are provided on the opposite side walls of the base plate and the cover plate.
[0021] By adopting the above technical solution, anti-slip textures are provided on the opposite side walls of the base plate and the cover plate. By increasing the friction of their surfaces, the cell culture plate is prevented from sliding during use, making it easier for operators to handle and move the cell culture plate, and further improving its stability and safety in use.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By utilizing the first magnetic component, the second magnetic component, the convex strip, and the groove, the mutual attraction between the first magnetic component and the second magnetic component increases the adsorption force between the cover plate and the bottom plate, making the cover plate and the bottom plate fit tightly together and avoiding contamination problems during cell culture. At the same time, the convex strip and the groove form an interlocking structure, which minimizes the risk of slippage or tilting when the upper and lower culture plates are stacked, further improving the stability of the upper and lower stacking structure of the porous cell culture plate.
[0024] 2. With the help of the limiting part, the middle part of the two limiting parts protrudes towards each other, which can limit the insertion position of the protrusion. At the same time, the limiting part reduces the contact area between the anti-slip washer and the protrusion, thereby reducing the friction between the anti-slip washer and the protrusion, making it easier for the protrusion to be smoothly inserted into the limiting groove and improving the operating efficiency.
[0025] 3. By applying a lubricating coating to the limiting part of the anti-slip washer, the friction is reduced, making it easier for the protrusion to be inserted into or pulled out of the limiting groove, thus improving work efficiency. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-4This application will be described in further detail.
[0032] This application discloses a porous cell culture plate.
[0033] Example 1:
[0034] Reference Figure 1 and Figure 2 A porous cell culture plate includes a base plate 1 and a cover plate 2. A boss 3 is integrally formed on the top wall of the base plate 1. Six circular culture tanks 4 are formed within the boss 3 and the base plate 1, and are evenly spaced. Three culture tanks 4 form a row, and the six circular culture tanks 4 are arranged in two rows and three columns. The cover plate 2 is located at the top opening of the six culture tanks 4, and covers the boss 3. A rounded corner 13 is formed at one corner of the cover plate 2, the base plate 1, and the boss 3 to facilitate a tight fit between the cover plate 2 and the boss 3, improving the efficiency of operator work.
[0035] Eight first magnetic elements 5 are embedded in the top wall of the base plate 1, and the eight first magnetic elements 5 are located around the boss 3. Eight second magnetic elements 6 are embedded in the bottom wall of the cover plate 2. The eight first magnetic elements 5 and the eight second magnetic elements 6 correspond one-to-one, and the second magnetic elements 6 and the first magnetic elements 5 attract each other. In this application, both the first magnetic elements 5 and the second magnetic elements 6 can be magnets.
[0036] When the cover plate 2 is placed on the boss 3, the first magnetic component 5 and the second magnetic component 6 attract each other, enhancing the adsorption capacity between the cover plate 2 and the bottom plate 1, so that the cover plate 2 and the bottom plate 1 fit tightly together, which can not only improve the sealing of the porous cell culture plate, but also make the stacking structure between the upper culture plate and the lower culture plate more stable.
[0037] An annular groove 7 is provided on the bottom wall of the base plate 1, and an annular protrusion 8 is fixedly installed on the top wall of the cover plate 2. When the two cell culture plates are stacked one on top of the other, the protrusion 8 on the top wall of the lower cover plate 2 is inserted into the groove 7 on the bottom wall of the upper base plate 1, so that the upper and lower porous cell culture plates do not slide or tilt during the stacking operation, and further improve the stability of the stacking structure.
[0038] Anti-slip textures 14 are installed on the opposite side walls of the cover plate 2 and the bottom plate 1. The anti-slip textures 14 are wavy and increase the friction of their surfaces to prevent the cell culture plate from sliding during use. This makes it easier for operators to handle and move the cell culture plate, further improving its stability and safety.
[0039] The implementation principle of Embodiment 1 of this application is as follows: When the cover plate 2 is placed on the protrusion 3, the first magnetic component 5 and the second magnetic component 6 attract each other, thereby enhancing the adsorption force between the cover plate 2 and the bottom plate 1. This ensures that the cover plate 2 and the bottom plate 1 of the same porous cell culture plate fit tightly together, improving the sealing performance of the culture tank 4. Simultaneously, when two cell culture plates are stacked vertically, the protrusion 8 on the top wall of the lower cover plate 2 inserts into the groove 7 on the bottom wall of the upper bottom plate 1, preventing the porous cell culture plates from sliding or tilting during stacking operations, further improving the stability of the stacking structure.
[0040] Example 2:
[0041] Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that an annular anti-slip pad 9 is fixedly embedded on the bottom wall of the base plate 1, and an annular limiting groove 10 is opened on the bottom wall of the anti-slip pad 9. In the two cell culture plates stacked on top of each other, the protrusion 8 on the lower cover plate 2 is inserted into the limiting groove 10 of the anti-slip pad 9 at the bottom of the upper base plate 1.
[0042] The base plate 1 increases the friction between the base plate 1 and the top wall of the lower porous cell culture plate through the anti-slip pad 9 to stabilize the stacked structure. At the same time, the protrusion 8 is inserted into the limiting groove 10 to limit the position of the protrusion 8 and prevent the stacked structure of the porous cell culture plate from slipping due to position movement or contact.
[0043] The anti-slip washer 9 has limiting portions 11 formed on both opposite side walls of the limiting groove 10. The two limiting portions 11 are symmetrically arranged along the width direction of the limiting groove 10, and the middle of the two limiting portions 11 protrudes towards each other. The width of the limiting portions 11 gradually increases from the upper and lower ends towards the middle position, and the limiting portions 11 of the anti-slip washer 9 are coated with a lubricating coating 12. In this application, the lubricating coating 12 can be a Teflon coating.
[0044] When the protrusion 8 is inserted into the limiting groove 10, the opposite side walls of the protrusion 8 pass through the protruding ends of the limiting parts 11 that are close to each other and are then inserted into the limiting groove 10. The middle parts of the two limiting parts 11 protrude towards each other, which limits the insertion position of the protrusion 8, making it easier for the protrusion 8 to be smoothly inserted into the limiting groove 10 and improving operating efficiency.
[0045] The width of the limiting part 11 gradually increases from the upper and lower ends toward the middle position, so that the two limiting parts 11 clamp the opposite side walls of the protrusion 8 through their close-to-each ends, making it easy for the protruding position of the limiting part 11 to fit tightly with the side wall of the protrusion 8.
[0046] Meanwhile, the limiting part 11 of the anti-slip washer 9 is coated with a lubricating coating 12, which reduces friction and facilitates the insertion or removal of the protrusion 8 into the limiting groove 10, thereby improving work efficiency and making the limiting part 11 more stable and easier to operate during the insertion process, thus improving the safety and service life of the multi-well cell culture plate.
[0047] The implementation principle of Embodiment 2 of this application is as follows: When the cover plate 2 is placed on the boss 3, the boss 3 is inserted into the limiting groove 10 on the anti-slip washer 9. When the protruding strip 8 is inserted into the limiting groove 10, the opposite side walls of the protruding strip 8 pass through the protruding ends of the limiting part 11 that are close to each other and then insert into the limiting groove 10. The middle part of the two limiting parts 11 protrudes towards each other, which plays a limiting and clamping role on the insertion position of the protruding strip 8, making the limiting part 11 more stable and the operation smoother during the insertion process, so that the protruding strip 8 can be smoothly inserted into the limiting groove 10, thereby improving the safety and service life of the multi-well cell culture plate and improving the operating efficiency.

Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
