Description

Constant temperature type bacterial strain culture device for preventing and treating infectious diseases special for veterinarian

Technical Field

The invention relates to the technical field of strain culture equipment, in particular to a constant temperature strain culture device for preventing and treating infectious diseases special for veterinarian.

Background

Infectious diseases are a group of diseases that can be transmitted between animals, human to human, or human to animal due to pathogenic bacteria, viruses, and other pathogens. It has a relatively fixed period of infection during which the infected person can expel the pathogen and contaminate the environment, thereby causing the transmission of the disease. Thus, veterinary medicine often requires strain culture of animal excretions, vomit, etc. to determine the type of disease during the treatment of some animal diseases.

However, for strain culture of infectious diseases, the strain culture is provided with a great difficulty because of the relatively strong infectivity of the infectious diseases. Thus, in the cultivation of infectious pathogen strains, it is often necessary to achieve a sealed cultivation, i.e. cultivation of the strain in a relatively closed environment. However, the culture apparatus for strains currently used cannot be directly used for culturing infectious pathogen strains due to poor sealing. If the strain is directly used for culturing infectious pathogen strains, a great infection probability can be brought to operators, and certain safety problems are caused.

In addition, the conventional constant temperature device cannot fully contact bacterial liquid with gas, and particularly for the aerobic culture process, a culture system cannot be uniform, so that the difficulty of strain culture is further increased.
