Description

Bacteria culture bottle capable of exchanging gas Technical Field The utility model belongs to the technical field of culture flasks, and particularly relates to a bacteria culture flask capable of exchanging gas. Background In vitro culture of cells and tissues has become an essential element of life research and practice. The culture bottles, culture plates and culture dishes used for providing the in-vitro culture environment of cells have good transparency, are nontoxic and sterile, and are required to be subjected to surface modification treatment so as to be capable of adhering to, splitting and growing. The culture bottle is used as a core tool for microorganism culture, and the sterile environment control and the operation convenience are considered in the gas exchange process. In the prior art, chinese patent publication No. CN219099155U discloses a bacteria culture bottle capable of exchanging gas, which realizes gas filtration and unidirectional discharge by arranging a filter element and a conical block structure in an exhaust hole, and solves the problem of germ leakage to a certain extent. However, the technical scheme still has the obvious defects that firstly, the filter element is arranged below the conical block and penetrates into the bottle body, during the bacterial or virus culture process, the culture solution in the bottle is easy to directly contact with the filter element due to shaking, vibration and other operations, so that the filter element is polluted or blocked by the liquid, the gas exchange efficiency and the filtering effect are affected, secondly, the filter element is integrated in the bottle plug, the bottle body and the bottle plug are required to be completely separated and detached during replacement, the operation is complicated, the risk of destroying the sterile environment is increased, and the requirement of a high-biosafety-level culture scene is difficult to meet.
