Abstract
Description
Technical Field
[0001] This invention belongs to the field of cell culture plates, and specifically relates to a cell culture plate that is easy to observe. Background Technology
[0002] In life science and medical research, cell culture is a crucial experimental technique, and cell culture plates, as commonly used tools, are essential for observing cell growth. With increasing demands for precision in scientific research, traditional culture plates are failing to meet requirements in terms of ease of observation, airtightness, and stability. Developing novel, easily observable cell culture plates has become a trend, aiming to provide researchers with more efficient and reliable experimental equipment, facilitate the smooth conduct of cell culture experiments, and promote the development of research in the life sciences.
[0003] Existing technologies have developed some cell culture plates that are easy to observe. For example, Chinese patent with publication number "CN221662954U" discloses "a vessel for easy observation of cell morphology". By using the combination of the culture dish and the cover plate, the cover plate does not need to be removed when initially observing cell morphology, reducing the chance of cell contamination. The height-adjustable cell observation microscope can be rotated at the center of the culture dish and the cover plate to observe the cell morphology in the peripheral culture chamber, which is convenient to use.
[0004] Although the combination of the culture dish and the cover plate allows for initial observation of cell morphology without removing the cover plate, reducing the chance of cell contamination, the aforementioned structure cannot effectively seal the cells and does not effectively isolate external bacteria. Furthermore, care must be taken to ensure that the cover plate does not slip off during handling, as it cannot effectively secure the cover plate to the upper end of the mounting base. Utility Model Content
[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a cell culture plate that is easy to observe, so as to solve the problems of cell culture plates.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A cell culture plate for easy observation includes a mounting base. A limiting plate is slidably mounted inside the upper end of the mounting base. A placement plate is integrally formed at the end of the limiting plate away from the mounting base. A mounting protrusion is integrally formed on the outer ring of the placement plate. A second sealing strip is fixedly mounted at the bottom of the mounting protrusion. A first sealing strip is fixedly mounted at the upper end of the mounting protrusion. The second sealing strip is slidably mounted inside the mounting base. Multiple placement slots are formed inside the end of the placement plate away from the limiting plate. A viewing dish slot and an observation microscope slot are formed on one side of each of the multiple placement slots. A cover plate is engaged at the upper end of the mounting base. The first sealing strip is slidably mounted inside the end of the cover plate near the mounting base. A culture dish is placed inside the placement slot.
[0008] As a preferred technical solution, a limiting groove is provided at the bottom of the mounting base, and the limiting plate is slidably installed inside the mounting base through the limiting groove. A second sealing groove is provided on the outer ring above the limiting groove inside the mounting base, and the second sealing strip is slidably installed inside the second sealing groove.
[0009] As a preferred technical solution, the end of the cover plate away from the mounting base has an internal mounting frame, and a transparent plate is fixedly installed in the inner circle of the mounting frame. The end of the cover plate close to the mounting plate has a first sealing groove, and the first sealing strip is slidably installed inside the first sealing groove.
[0010] As a preferred technical solution, the upper end of the culture dish is provided with a top cover, and a convex pad is integrally formed on one end of the top cover near the culture dish. The culture dish is provided with a storage groove, and the convex pad is slidably installed on the inner ring of the upper end of the storage groove.
[0011] As a preferred technical solution, a circular hole is provided at the center of the upper cover, and a telescopic rod is provided inside the circular hole. A cell observation microscope is fixedly installed at the upper end of the telescopic rod.
[0012] As a preferred technical solution, the outer ring of the mounting base is integrally formed with a second fixing plate on both sides, and the two second fixing plates are provided with insertion grooves, and the insertion grooves are provided with slots on both sides.
[0013] As a preferred technical solution, both sides of the cover plate are integrally formed with a first fixing plate, and one end of the two first fixing plates near the second fixing plate is integrally formed with a plug-in plate. Both sides of the two plug-in plates are provided with slots, and springs are fixedly installed inside the slots. A locking block is fixedly installed at the end of the spring away from the slot. The plug-in plate is inserted into the second fixing plate through the plug-in slot, and the locking block is engaged and installed inside the locking slot.
[0014] In summary, the present invention has the following main advantages:
[0015] First, the placement plate with the culture dish is slidably fitted into the mounting base through the limiting plate and the limiting groove at the bottom of the mounting base. At this time, the second sealing strip at the bottom of the outer ring of the placement plate will accurately slide into the second sealing groove on the outer ring above the limiting groove inside the mounting base, which plays a preliminary sealing role and prevents external pollutants from entering the culture environment.
[0016] Second, the cover plate is inserted into the insertion slots of the second fixing plates on both sides of the outer ring of the mounting base through the insertion plates on the first fixing plates on both sides. During the insertion process, the spring in the slot of the insertion plate pushes the locking block, so that it is locked in the slot, realizing a stable connection between the cover plate and the mounting base. At the same time, the first sealing strip at the upper end of the mounting ring will slide into the first sealing groove inside the end of the cover plate near the mounting plate, further enhancing the sealing effect and forming a relatively closed and stable culture space.

[0026] refer to Figures 5 to 6 The mounting base 5 has a limiting groove 13 at its bottom. The limiting plate 15 is slidably installed inside the mounting base 5 through the limiting groove 13. A second sealing groove 28 is provided on the outer ring of the mounting base 5 above the limiting groove 13. A second sealing strip 29 is slidably installed inside the second sealing groove 28. A mounting frame 30 is provided inside the end of the cover plate 2 away from the mounting base 5. A transparent plate 1 is fixedly installed on the inner ring of the mounting frame 30. A first sealing groove 14 is provided inside the end of the cover plate 2 near the mounting plate 18. A first sealing strip 17 is slidably installed inside the first sealing groove 14. The substrate containing the culture medium... The placement plate 18 of the dish 10 is slidably engaged with the limiting groove 13 at the bottom of the mounting base 5 via the limiting plate 15, and is embedded in the mounting base 5. At this time, the second sealing strip 29 at the bottom of the outer ring 16 of the placement plate 18 will accurately slide into the second sealing groove 28 located on the outer ring above the limiting groove 13 inside the mounting base 5, which plays a preliminary sealing role to prevent external pollutants from entering the culture environment. The first sealing strip 17 will slide into the first sealing groove 14 inside the end of the cover plate 2 near the placement plate 18, further strengthening the sealing effect and forming a relatively closed and stable culture space.
[0027] refer to Figure 4 The culture dish 10 has a top cover 7 at its upper end. A raised pad 8 is integrally formed at one end of the top cover 7 near the culture dish 10. The culture dish 10 has a storage groove 9 inside. The raised pad 8 is slidably installed on the inner ring of the upper end of the storage groove 9. A circular hole 6 is opened at the center of the top cover 7. A telescopic rod 12 is installed inside the circular hole 6. A cell observation microscope 11 is fixedly installed at the upper end of the telescopic rod 12. Researchers open the cover 2, place the culture dish 10 into the observation dish groove 20, and then pick up the cell observation microscope 11. They can operate the telescopic rod 12 on the top cover 7 of the culture dish 10. By gently pulling or pushing the telescopic rod 12, researchers can lower or raise the cell observation microscope 11 to a suitable observation position. The cell observation microscope 11 can penetrate deep into the culture dish 10, allowing close observation of the microscopic structure and specific changes of cells, providing more accurate data support for experiments.
[0028] refer to Figures 2 to 3 The mounting base 5 has two integrally formed second fixing plates 4 on both sides of its outer ring. Each of the two second fixing plates 4 has an insertion groove 26 inside, and slots 25 are formed on both sides of the insertion groove 26. The cover plate 2 has two integrally formed first fixing plates 3 on both sides. One end of each of the two first fixing plates 3 adjacent to the second fixing plate 4 has an integrally formed insertion plate 27. Both sides of the insertion plates 27 have slots 22 inside, and springs 24 are fixedly installed inside each slot 22. The springs 24 are positioned away from the slots 22. Each end is fixedly installed with a locking block 23. The plug plate 27 is inserted into the second fixed plate 4 through the plug groove 26. The locking block 23 is engaged in the slot 25. The cover plate 2 is inserted into the plug groove 26 of the second fixed plate 4 on both sides of the outer ring of the mounting base 5 through the plug plates 27 on the first fixed plate 3 on both sides. During the insertion process, the spring 24 in the slot 22 of the plug plate 27 pushes the locking block 23, so that it is engaged in the slot 25, thereby realizing a stable connection between the cover plate 2 and the mounting base 5.
[0029] Operating principle and advantages: Before use, place the culture dish 10 in the placement groove 21 of the mounting plate 18. The upper cover 7 of the culture dish 10 slides with the inner ring of the upper end of the culture dish 10 storage groove 9 through the convex pad 8, achieving a sealed installation and ensuring the stability of the culture environment. At the same time, the telescopic rod 12 and cell observation microscope 11 installed in the central circular hole 6 of the upper cover 7 provide preliminary preparation for cell observation. Next, the mounting plate 18 with the culture dish 10 slides with the limiting plate 15 through the limiting groove 13 at the bottom of the mounting base 5 and is embedded in the mounting base 5. At this time, the second sealing strip 29 at the bottom of the outer ring convex ring 16 of the mounting plate 18 will accurately slide into the second sealing groove 28 on the outer ring above the limiting groove 13 inside the mounting base 5, playing a preliminary sealing role and preventing external... When contaminants from the environment enter the culture environment, the cover plate 2 is then inserted into the insertion slots 26 of the second fixing plates 4 on both sides of the outer ring of the mounting base 5 via the insertion plates 27 on the first fixing plates 3 on both sides. During the insertion process, the spring 24 in the slot 22 of the insertion plate 27 pushes the locking block 23, causing it to engage and install itself inside the locking slot 25, thus achieving a stable connection between the cover plate 2 and the mounting base 5. At the same time, the first sealing strip 17 at the upper end of the mounting ring 16 slides into the first sealing groove 14 inside one end of the adjacent mounting plate 18 of the cover plate 2, further enhancing the sealing effect and forming a relatively closed and stable culture space. When it is necessary to observe the cells, researchers can choose different observation methods. On the one hand, they can directly observe the cells through the transparent plate 1 fixed in the inner ring of the mounting frame 30 of the cover plate 2 from the culture plate. Macroscopic observation is performed from above to understand the overall distribution and growth status of cells. The presence of the transparent plate 1 not only ensures visibility but also maintains the airtightness of the culture environment. On the other hand, if more detailed observation is needed, researchers can open the cover plate 2, place the culture dish 10 into the viewing dish slot 20, and then pick up the cell observation microscope 11. By operating the telescopic rod 12 on the cover 7 of the culture dish 10, researchers can gently pull or push the telescopic rod 12 to lower or raise the cell observation microscope 11 to adjust it to a suitable observation position. The cell observation microscope 11 can penetrate deep into the culture dish 10 to observe the microscopic structure and specific changes of cells up close, providing more accurate data support for experiments. In addition, the viewing dish slot 20 and the observation dish slot 20 on one side of the placement slot 21 on the placement plate 18 are also included. The observation slot 19 also facilitates observation operations. It can temporarily hold a removed cell observation microscope 11, allowing researchers to flexibly switch between different observation methods and operations. During cell culture, researchers may need to add culture medium, extract cell samples, etc. Due to the excellent sealing structure of the culture plate, these operations can be performed by carefully opening the top cover 7, minimizing the impact of the external environment on the cells inside the culture dish 10. After the operation, the top cover 7 should be sealed immediately to ensure a stable culture environment. When the experiment is finished or the culture dish 10 needs to be replaced, researchers can press the latch 23 on the cover plate 2 to disengage it from the slot 25, easily removing the cover plate 2. Then, the mounting plate 18 can be pulled out from the mounting base 5.Petri dish 10 was removed for further processing. The entire disassembly and replacement process was simple and quick, facilitating the continuous conduct of experiments and equipment maintenance.
