Description

Technical Field

[0001] The utility model relates to the technical field of cell culture, in particular to a cell culture device. Background Art

[0002] Cell culture is a common microbiology laboratory technique primarily used to cultivate cell colonies. During the cell culture spreading process, a certain amount of diluted sample suspension is dropped onto the surface of a sterile plate. A sterile spreading rod is then used to evenly distribute the dilution across the entire surface of the plate. The plate is then inverted and incubated at a suitable temperature to allow the growth of single cell colonies. These colonies can then be further isolated and cultured for research or other applications.

[0003] Currently, most cell culture coatings are done manually. However, during manual operation, the coating pressure and speed may be inconsistent, resulting in uneven cell distribution on the surface of the culture dish, affecting the accuracy and reliability of the experimental results. In addition, different operators may have different techniques when manually coating, which will reduce the comparability between experiments. Utility Model Content

[0010] With the above technical solution, the second bearing fixedly connected to the inner wall of the protection box is used to improve the support and position limiting of the fixed column, thereby improving the stability of the fixed column during rotation.

[0011] As a further improvement of the above solution, the driven gear, the driving gear and the transmission shaft are all located inside the protective box, and a support rod is fixedly connected to the upper surface of the base.

[0012] Through the above technical solution, the driven gear, driving gear and transmission shaft are shielded by the protective box, which can prevent accidental contact with high-speed rotating gears, reduce operational risks, and improve work safety.

[0015] As a further improvement of the above solution, the output end of the electric telescopic rod passes through the fixed plate and is fixedly connected to a coating rod, and a protective cover is fixedly connected to the surface of the coating rod.

[0016] Through the above technical solution, the protective cover is used to shield the top of the culture dish, preventing external dust and bacteria in the air from entering the interior of the culture dish, making the results of subsequent experiments more accurate.

[0017] As a further improvement of the above solution, the lower end of the coating rod is located inside the culture dish, and the protective cover is located at the upper end of the culture dish.

[0018] Through the above technical solution, when the culture dish rotates, the coating rod contacts the inner bottom wall of the culture dish, thereby evenly spreading the sample suspension droplets, ensuring the uniformity of the coating, avoiding manual coating by the staff, and thus reducing the labor intensity of the staff.

Specifically, the inspection door can be opened to inspect the drive components inside the protective box, which is convenient for subsequent maintenance and improves practicality. The protective cover shields the culture dish to prevent external dust and bacteria in the air from entering the interior of the culture dish, making the results of subsequent experiments more accurate.
