Abstract
Description
Technical Field
[0001] This utility model relates to the field of cell culture technology, and in particular to a transfer device for cell culture plates. Background Technology
[0002] Cell culture plates are widely used as experimental consumables in fields such as biological experiments, drug screening, and cell engineering for cell culture. During cell culture, cell culture plates often need to be transferred multiple times, such as being removed from the incubator, placed into observation equipment, or transported to other experimental areas for subsequent operations.
[0003] Existing cell culture plates consist of two parts: a lid and a base, without any fixing structure in between. During plate transfer, researchers may easily lift the lid directly (leading to accidental opening of the cell culture plate lid in a non-sterile environment), exposing the cells in the base to air. In a non-sterile environment, this direct contact between the cells and air causes cell contamination and experimental failure. Furthermore, the lid of the cell culture plate can easily slip off during transfer, causing cell contamination as well.
[0004] Even though existing cell culture plates have anti-slip strips on the side walls to increase stability, this doesn't completely solve the problem of cell contamination caused by researchers directly lifting the lid or the lid slipping during cell transfer. However, to ensure sufficient gas exchange and maintain specific temperature and humidity in the incubator, the base and lid of the cell culture plate cannot fit tightly together. Furthermore, to prevent the lid from slipping or accidentally opening during cell culture plate transfer and exposing cells to air, a specialized cell culture plate transfer device needs to be developed. This device could further improve experimental success rates and prevent cell contamination. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a cell culture plate transfer device, which aims to improve the problems of cell culture plates being prone to slipping off the lid or being accidentally opened during the transfer process, resulting in cell exposure to air and causing cell contamination.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A cell culture plate transfer device includes a base, a top cover on the top of the base, a cavity between the base and the top cover for placing the cell culture plate, a clamping plate fixedly connected to the side wall of the base, a fixing frame fixedly connected to the side wall of the top cover, a buckle plate rotatably connected to the side wall of the fixing frame, a cavity inside the buckle plate, the end of the clamping plate fitting into the cavity, and a spring between the top cover and the buckle plate.
[0008] As a further description of the above technical solution:
[0009] One end of the spring is fixedly connected to the side wall of the upper cover, and the other end of the spring is fixedly connected to the side wall of the buckle plate.
[0010] As a further description of the above technical solution:
[0011] The base has an inner edge, and the cell culture plate is slidably connected to the inside of the base and fits against the inner edge.
[0012] As a further description of the above technical solution:
[0013] The inner wall of the base is provided with a limiting groove, which matches the anti-slip strip on the side wall of the cell culture plate, and one side wall of the anti-slip strip is slidably connected to the inside of the limiting groove.
[0014] As a further description of the above technical solution:
[0015] The base has a slot at the bottom, which is used to push the cell culture plate upward from the bottom, making it easy to remove the cell culture plate.
[0016] As a further description of the above technical solution:
[0017] The base sidewall has an outer edge, the upper cover is slidably connected to the base sidewall, and the lower surface is in contact with the outer edge.
[0018] As a further description of the above technical solution:
[0019] Anti-slip pads are fixedly connected to the middle of the side wall of the base and the top cover, anti-slip strips are fixedly connected to the outer side wall of the base, and foot pads are fixedly connected to the four corners of the bottom of the base.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the sliding fit structure between the top cover and the base, the cooperation between the clamping plate and the buckle plate, and the automatic rebound function of the spring ensure the stability of the connection between the base and the top cover. Placing the cell culture plate in the cavity between the base and the top cover can effectively prevent the cell culture plate from slipping off or being accidentally opened during the transfer process, which would lead to cell contamination. In addition, the transfer device is easy to open and close quickly, which improves the convenience and stability of operation.
[0022] 2. In this utility model, the sliding fit structure between the inner edge of the base and the cell culture plate ensures the stability of the placement. The cell culture plate is inserted into the cavity between the base and the top cover, and the anti-slip strip slides into the limiting groove, which can further effectively prevent the cell culture plate from shaking or shifting inside the base when moving, thus enhancing the stability of the placement.

[0030] 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.
[0031] Reference Figures 1-5This utility model provides an embodiment of a cell culture plate transfer device, comprising a base 1, with a top cover 2 for sealing protection to prevent the cell culture plate from slipping, especially the cell culture plate lid, from slipping or accidentally opening, ensuring the stability of the cell culture environment and the safety of cell transfer. A cavity is provided between the base 1 and the top cover 2 for placing the cell culture plate 8, supporting the cell culture dish or culture plate, and preventing the cell culture plate from slipping, especially the cell culture plate lid, from slipping or accidentally opening. A retaining plate 3 is fixedly connected to the side wall of the base 1 to provide a stable connection point. A fixing frame 4 is fixedly connected to the side wall of the top cover 2, and a buckle plate 5 is rotatably connected to the side wall of the fixing frame 4. The buckle plate 5 has a cavity inside, and the end of the retaining plate 3 matches the cavity. The retaining plate 3 and the buckle plate 5 form a stable locking structure, effectively preventing the top cover 2 from loosening during transfer or use. A spring 6 is provided between the top cover 2 and the buckle plate 5. One end of spring 6 is fixedly connected to the side wall of the upper cover 2, and the other end of spring 6 is fixedly connected to the side wall of the buckle plate 5. It has an automatic rebound and buffer function, which makes it easy to quickly open or close the upper cover 2, improving the convenience and safety of operation. The base 1 has an inner edge 7. The cell culture plate 8 is slidably connected to the inside of the base 1 and fits against the inner edge 7, ensuring the stability of the cell culture plate 8 and preventing shaking, slippage or accidental opening of the cover during use. The side wall of the base 1 has an outer edge 12. The upper cover 2 is slidably connected to the side wall of the base 1, and its lower surface fits against the outer edge 12, which further improves the stability from a structural perspective and ensures the safety and stability of the cell culture plate 8 during transfer. Anti-slip pads 13 are fixedly connected to the middle of the side walls of the base 1 and the outer side wall of the base 1. Anti-slip strips 11 are fixedly connected to the outer side wall of the base 1, which can increase the friction when gripping the hand and prevent slippage. Foot pads 14 are fixedly connected to the four corners of the bottom of the base 1, which have the functions of shock absorption, anti-slip and anti-scratch experimental platform. The bottom of the base 1 has a groove 15, through which the cell culture plate 8 can be pushed upward from the bottom, making it easy to remove the cell culture plate 8.
[0032] Furthermore, a limiting groove 10 is also provided on the inner wall of the base 1. When the side wall of the cell culture plate to be transferred is provided with an anti-slip strip 9, the limiting groove 10 matches the anti-slip strip 9, and the side wall of the anti-slip strip 9 is slidably connected inside the limiting groove 10, which further ensures the stability of the cell culture plate 8 and the safety during transfer.
[0033] Working principle: When transferring cell culture plates, the transfer device should first be sterilized. Then, in a sterile environment, the latch 5 is moved to rotate around the fixing frame 4, while simultaneously stretching the spring 6. When the latch 5 separates from the locking plate 3, the upper cover 2 and the base 1 are no longer restricted, allowing the upper cover 2 to be lifted upwards and fully opened. The cell culture plate 8 is then placed into the cavity between the base 1 and the upper cover 2, and pressed downwards. If the cell culture plate 8 to be transferred has anti-slip strips 9 on its side wall, pressing downwards will allow the anti-slip strips 9 to slide into the limiting groove 10 for engagement. If the cell culture plate 8 to be transferred does not have anti-slip strips on its side wall, pressing downwards will still allow the cell culture plate to engage. The cell culture plate 8 fits snugly against the inner edge 7, ensuring the stability of the cell culture plate 8. Finally, the top cover 2 is placed on top. As the top cover 2 is pressed down, the lower end of the retaining plate 5 slides along the end of the clamping plate 3 and adaptively deflects on the fixing frame 4 along its inclined surface, stretching the spring 6. When the internal cavity of the retaining plate 5 aligns with the end of the clamping plate 3, the spring 6 loses its tension, causing the retaining plate 5 to reset, thus locking the clamping plate 3 and the retaining plate 5 together. This completes the locking and closing of the base 1 and the top cover 2, firmly fixing the cell culture plate 8 within the transfer device. This prevents the cell culture plate 8 from slipping during transfer or from being accidentally opened, thus protecting the cells from air exposure and contamination, thereby improving the accuracy and convenience of cell experiments. After transfer, under sterile conditions, the retaining plate 5 is moved to separate it from the clamping plate 3. The cell culture plate 8 is then pushed upwards through the slot 15 at the bottom of the base 1 and simultaneously pulled upwards to remove it from the transfer device for subsequent experiments.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
