Description

Technical Field

[0001] The utility model relates to the technical field of animal experimental appliances, in particular to a negative pressure sampling table for experimental animals. Background Art

[0002] When conducting animal experiments, the experimental environment must be isolated from the outside world to prevent the leakage of harmful gaseous substances and the splashing of solid and liquid substances into the external environment, which could contaminate the environment. This is typically achieved by creating a negative pressure environment within the collection table, such as with a fume hood and splash-proof design. This is typically achieved by reducing the area used for experiments and drug manipulation. Common laboratory animal collection tables lack efficient ventilation within the collection table, resulting in an unstable internal negative pressure environment. The commonly used reduction in the experimental area also makes experimental operations inconvenient. Utility Model Content
