Description

Technical Field

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

[0002] In the field of cell culture, maintaining a constant and suitable environment is crucial for cell growth and the accuracy of experimental results. Although traditional cell culture incubators can provide a certain degree of environmental control, in actual operation they often suffer from problems such as unstable air pressure and insufficient sealing. These problems may cause changes in the culture environment, affect the growth state of cells, and even lead to experimental failure. In addition, existing incubators are mostly designed with a simple lid. This design not only has poor sealing, but also makes it easy for the lid to open accidentally due to vibration or misoperation during operation, thereby destroying the stability of the internal environment.

[0003] To address these issues, the market urgently needs a cell culture incubator that can provide a constant pressure environment, exhibit high sealing properties, and be easy to operate. Although some improvement solutions have been proposed, such as adding sealing strips and optimizing locking mechanisms, these solutions either increase operational complexity or fail to fundamentally address the issue of air pressure fluctuations. Therefore, developing a cell culture incubator that can effectively maintain a constant pressure while ensuring a good seal has become a current research hotspot. Utility Model Content

[0009] Beneficial effects:

[0010] 1. This utility model realizes precise control of the gas composition and pressure in the incubator by setting up air inlet pipes and exhaust ports on both sides of the box and equipping them with corresponding valves. Users can flexibly adjust the air intake and exhaust volumes according to experimental requirements to maintain the optimal gas environment, which is of great significance for simulating specific physiological conditions or conducting special experiments.

[0011] 2. The design of the locking buckle combines the structure of the screw and the turntable, allowing the operator to easily control the tightness of the lock by rotating the turntable. The evenly distributed locking buckles use the ridges as support points to provide a stable locking force. Even when external conditions change (such as temperature fluctuations and transportation vibrations), the internal constant pressure state can be maintained, providing a stable growth environment for cells.
