Anoxic device for clinical animal experiments

Abstract

The present invention discloses an anoxic device for clinical animal experiments and relates to the field of clinical animal experimental equipment. The anoxic device comprises a closed experimental box, an oxygen concentration control system, a gas treatment system and an animal behavior observation and recording device; the oxygen concentration control system comprises a nitrogen gas source andan oxygen gas source, each of the gas sources communicates with the experimental box via pipelines and is provided with a control valve, and the oxygen concentration control system is used for regulating an oxygen concentration in the experimental box; the gas treatment system comprises a gas extracting pump and a treatment tank provided with quicklime, gas extracted by the gas extracting pump from the experimental box enters into the treatment tank to react and returns to the treatment tank, and the gas treatment system is used to control a carbon dioxide concentration, humidity and gas pressure in the experimental box; and the animal behavior observation and recording device comprises a web camera, a cloud server and a remote monitoring device for monitoring and recording animal behaviors in real time. The device realizes automatic control and automatic data collection and recording of the experimental box, is accurate in experimental results, and provides accurate data for clinicalmedical researches.

Description

technical field [0001] The invention relates to the field of clinical animal experiment equipment, in particular to a hypoxia device for clinical animal experiments. Background technique [0002] When the supply of oxygen to the tissue is insufficient, or when the tissue is unable to utilize oxygen, abnormal changes may occur in the function and metabolism of the body. This pathological process is called hypoxia. In the mouse hypoxia experiment, by observing the physiological state of the mice after being stimulated by the hypoxic environment, and combining it with other clinical experiments, it has great significance for the research of respiratory diseases. [0003] At present, there is no special hypoxia device for clinical animal experiments on the market. Some medical research units usually use self-assembled simple devices when carrying out such experiments, and feed small animals in a relatively airtight plastic storage box. For white mice, manually control the switc...

AI Technical Summary

Problems solved by technology

The experiment was completed with this simple device. Because the mice were fed for a long time, the oxygen concentration in the storage box could not be accurately controlled manually; at the same time, the experimental period was long, and the experimental data and animal behavior could not be accurately recorded by manual recording.
