Description

Technical Field

[0001] This utility model relates to the field of stem cell culture dish technology, specifically a stem cell preservation culture dish that is easy to assemble in multiple layers. Background Technology

[0002] Stem cells are a type of cell with unlimited or even immortal self-renewal capacity, capable of producing at least one type of highly differentiated daughter cell. Unlike ordinary cell culture, to maximize the function of stem cells in the human body, current stem cell preservation technologies typically require the storage of large numbers of stem cell samples. These technologies lack the ability to stack multiple culture dishes, necessitating more horizontal space for these dishes and occupying significant storage space. Furthermore, removing middle or lower layers of culture dishes requires first removing the upper layers one by one, increasing the number of steps and time involved, and lacking a function for rapid removal of culture dishes.

[0003] For example, the authorized patent document with application number CN202321103498.5 discloses a stem cell simulation culture device, including a culture chamber, multiple limiting columns, a support platform, a lid, a moving plate, and multiple sealing cylinders; the culture chamber is provided with a transparent plate; multiple limiting columns are installed on the upper surface of the culture chamber; the support platform is installed inside the culture chamber, and multiple placement slots and multiple sealing slots are provided on the upper surface of the support platform; the multiple sealing slots correspond one-to-one with the multiple placement slots, and each sealing slot is coaxial with each placement slot; the lid is provided with multiple limiting holes; the multiple limiting columns respectively cooperate to pass through the multiple limiting holes; the culture chamber is provided with two clamping components for pressing the lid; the outer peripheral surface of the moving plate located below the lid is provided with a sealing gasket; the bottom surface of the lid is provided with a lifting component for raising and lowering the moving plate; the bottom surface of the multiple sealing cylinders is provided with an adhesive layer.

[0004] The aforementioned patent has the problem that when removing a certain layer of the culture dish, it is not possible to remove the culture dish quickly. It is necessary to remove the upper layers of culture dishes one by one, which increases the number of steps and time required for the operation. Therefore, we need to provide a culture dish for stem cell preservation that is easy to assemble in multiple layers. Utility Model Content

[0023] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a culture dish for preserving stem cells that facilitates multi-layer assembly, comprising:

[0025] The arrangement includes a placement tray 1, a petri dish body 2, and a limiting mechanism 3. The petri dish body 2 is detachably installed inside the placement tray 1, and the placement tray 1 is equipped with a limiting mechanism 3 for limiting and fixing the petri dish body 2 and for rapid release.

[0026] The culture dish body 2 is installed in the placement tray 1, and the culture dish body 2 is clamped and fixed by the limiting mechanism 3, so as to quickly take out or put in the culture dish and reduce the operation time.

[0027] The limiting mechanism 3 includes a baffle 31, a contact frame 32, and an elastic squeezing component 33. The baffle 31 is fixedly installed inside the placement tray 1, the contact frame 32 is slidably installed inside the placement tray 1, and the elastic squeezing component 33 is used to limit and fix the petri dish body 2 between the baffle 31 and the contact frame 32.

[0028] Furthermore, the baffle 31 is fixedly installed between the two sides of the inner wall of the placement tray 1 to limit and abut against the culture dish body 2. When installing the culture dish body 2, the culture dish body 2 is placed on the placement tray 1 and moved until it is in contact with the baffle 31. At this time, the moving abutment frame 32 is in contact with the other side of the culture dish body 2, and the abutment frame 32 is affected by the elastic compression component 33. The abutment frame 32 always compresses the culture dish body 2, thereby limiting the culture dish body 2 between the baffle 31 and the abutment frame 32. The top of the abutment frame 32 is fixedly installed with a locking strip, which is engaged with the fixing ring 7 on the surface of the culture dish body 2 by the inner groove of the locking strip, making the fixation of the culture dish body 2 more secure.

[0029] The elastic compression assembly 33 includes a moving rod 331, a spring 332, a guide rod 333, and a guide groove 334. The moving rod 331 is hinged to one side of the contact frame 32. Two springs 332 are engaged between the moving rod 331 and the adjacent side of the placement plate 1. The two springs 332 are respectively sleeved on the outside of the two guide rods 333. The placement plate 1 has a guide groove 334. One end of the guide rod 333 is fixed to the moving rod 331, and the other end is slidably inserted into the guide groove 334.

[0030] It is worth noting that when removing the culture dish body 2, first pull the contact frame 32 outward. The contact frame 32 is hinged to the moving rod 331, which can be pulled to move the moving rod 331. Both springs 332 are set between the moving rod 331 and the placement plate 1. The movement of the moving rod 331 will stretch the two springs 332 until the contact frame 32 is disengaged from the placement plate 1. Rotate the contact frame 32 downward so that the contact frame 32 does not limit the culture dish body 2. At this time, stop pulling the contact frame 32. Under the action of the two springs 332, the moving rod 331 returns to its original position, and the culture dish body 2 can be removed, realizing the rapid removal of the culture dish body 2.

[0031] Limiting grooves 4 are provided on both sides of the inner wall of the placement plate 1, and the two ends of the moving rod 331 slide within the two limiting grooves 4 respectively;

[0032] The limiting grooves 4 on both sides of the inner wall of the placement plate 1 are used for the sliding of the two ends of the moving rod 331, which plays an auxiliary guiding role in the movement of the moving rod 331. The limiting grooves 4 provide rigid sliding tracks for the two ends of the moving rod 331, so that the moving rod 331 can only move horizontally in the preset direction when subjected to force (such as pulling the pull plate part 10), avoiding deviation or jamming, and ensuring smooth operation.

[0033] Both sides of the contact frame 32 are integrally machined with sliders 5, and the two sliders 5 slide in the two limiting grooves 4 respectively;

[0034] Specifically, the two sliders 5 slide within the two limiting grooves 4 respectively, and the two sliders 5 are fixedly installed on both sides of the contact frame 32, providing guidance for the movement of the contact frame 32. When the contact frame 32 is pulled to move, the sliders 5 on the surface of the contact frame 32 disengage from the limiting grooves 4, allowing the contact frame 32 to be rotated and adjusted without obstructing the movement path of the culture dish body 2.

[0035] The placement tray 1 has two guide rails 6 fixedly installed inside, and the surface of the petri dish body 2 has a fixing ring 7 integrally formed, which is fitted into the groove of the two guide rails 6;

[0036] It is worth noting that the design of the fixing ring 7 embedded in the groove of the guide rail 6 ensures that the petri dish body 2 is accurately aligned in the placement tray 1, avoiding horizontal offset or shaking. Through the sliding rail interlocking structure, users can easily push in or pull out the petri dish body 2 without complicated fixing steps, which significantly improves experimental efficiency.

[0037] The top four corners of the display tray 1 are provided with mounting posts 8, and the bottom of the display tray 1 is provided with four mounting bases 9 corresponding to the four mounting posts 8;

[0038] The four mounting bases 9 are equipped with magnetic blocks in their internal circular grooves, and the mounting posts 8 are metal posts. When the mounting posts 8 are inserted into the internal circular grooves of the mounting bases 9, they are attracted by the magnetic blocks. The attraction between the magnetic blocks and the metal posts allows the multi-layer trays 1 to be quickly aligned and fixed. The attraction force is evenly distributed at the four corners, avoiding tilting or misalignment caused by uneven force on one side. When stacking, the mounting posts 8 automatically attract into the mounting bases 9 without the need for additional locking steps. When disassembling, only vertical upward force is required to separate them, which is suitable for aseptic operation requirements.

[0039] The surface of the contact frame 32 is provided with a pull plate 10;

[0040] The pull plate part 10 adopts an outward convex structure, which is ergonomic and makes it easy for experimental personnel to operate with one hand. Even when wearing gloves, it is easy to apply force.

[0041] The side wall of the display tray 1 is provided with a label slot 11;

[0042] Label slot 11 provides a standardized labeling area, which makes it easy for experimenters to quickly identify different batches of stem cell samples and meet the needs of different experimental records.

[0043] The culture dish body 2 and its surface fixing ring 7 are both made of transparent material. The fully transparent structure ensures that the growth status of stem cells can be directly observed through a microscope without removing the culture dish. There are gaps between the stacked placement trays 1 for air circulation.

[0044] The device allows for the stacking of multiple placement trays 1 by inserting four mounting bases 9 at the bottom into four mounting posts 8 at the top of another placement tray 1. When it is necessary to remove the culture dish body 2 from the placement tray 1, the contact frame 32 is pulled outward first. The contact frame 32 is hinged to the moving rod 331, which can be pulled to move the moving rod 331. Two springs 332 are set between the moving rod 331 and the placement tray 1. The movement of the moving rod 331 will stretch the two springs 332 until the contact frame 32 is disengaged from the placement tray 1. The contact frame 32 is then rotated downward so that it does not limit the culture dish body 2. At this point, the contact frame 32 is no longer pulled. Under the action of the two springs 332, the moving rod 331 returns to its original position, and the culture dish body 2 can be removed, achieving rapid removal of the culture dish body 2.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
