Technical Field

The invention belongs to the technical field of bacterial culture, and particularly relates to an anti-pollution bacterial culture device for a clinical laboratory.

Background

The bacteria culture is a technology for artificially culturing bacteria, the bacteria are extremely wide in distribution, large in quantity and multiple in variety in nature, can benefit mankind and can also become a cause of diseases, most of the bacteria can be artificially cultured, namely, the bacteria are inoculated on a culture medium to be grown and propagated, the cultured bacteria are used for research, identification and application, the bacteria culture is a complex technology, the bacteria are everywhere, therefore, the whole culture process needs to be carried out according to the requirement of aseptic operation when the culture medium is prepared, otherwise, the external bacteria pollute a specimen and cause wrong results, the cultured pathogenic bacteria can cause cross infection once polluting the environment, while in the prior art, a bacteria culture dish is usually used for correspondingly culturing the bacteria, but the prior art still has the problems of pollution, wherein the common problem is that an inspection subject discharges and replaces a bacteria culture solution, need open the culture dish lid, at this in-process, often have other miscellaneous fungus to pollute former cultivation bacterium, this problem is solved at the in-process that uses to current bacteria culture dish and corresponding component not, to a certain extent, efficiency nature when having reduced the bacteria culture to bacteria culture dish is carrying out sealed operation and gas exchange's in-process, does not have better seal and gas exchange efficiency adjustability.
