Small animal oxygen consumption real-time monitoring system with hypoxic hypoxia bottle

Abstract

A small animal oxygen consumption real-time monitoring system with a hypoxic hypoxia bottle includes a breathing oxygen consumption monitoring device and the hypoxic hypoxia bottle for providing a closed experimental space for small animals. The problem that a conventional and typic oxygen-deficient device can not automatically monitor breathing and oxygen consumption is solved, the principle thatpressure fluctuation caused by photoelectric induction and chest contraction can be transmitted in a closed container is adopted, and the problem that people need to record the breathing frequency and observe the oxygen consumption by themselves in a conventional oxygen-deficient experiment is thus solved. The breathing oxygen consumption monitoring device is used, automatic recording of the hypoxic hypoxia oxygen consumption at any time and recording of breathing curves of different types of hypoxia can thus be achieved, by analyzing the breathing curves, the breathing excitability of different types of hypoxic experimental animals can be compared, the labor intensity of the experiment can be reduced, and the accuracy of experimental results can be improved.

Description

technical field [0001] The invention relates to a real-time monitoring system for small animal oxygen consumption with anoxic hypoxia bottle. Background technique [0002] Hypoxia is an important pathogenic factor or one of the important pathological processes in the pathogenesis of various diseases in the body, and it is also a problem that must be studied in plateau life, mine tunnel operations and aerospace flight. Various hypoxia experimental models are commonly used to simulate hypoxia in the experiments of medical colleges and universities, and the simulated hypoxia experimental models are used to conduct physiological, biochemical, pharmacological, pathophysiological and clinical research in order to explain various clinical diseases Pathological process, explore its effective treatment methods, etc. [0003] At present, in the "National Medical Experiment Planning Textbook for Colleges and Universities", the classic device for hypoxia experiments on non-anesthetized...

Problems solved by technology

[0005] The hypoxia bottle is an indispensable part of the hypoxia device. At present, in the "National Medical Experiment Planning Textbook for Colleges and Universities", the conventional hypoxia bottle is a 120 (some schools use 250) or 500ml jar. When the anoxic bottle is used, its disadvantages are: "The airtightness is poor, and when the experiment is halfway through, air leakage often occurs, causing the experiment to fail; Put it into the bottom of the bottle, so that the soda lime must be replaced after being used once because it is contaminated by animal feces, resulting in waste.”
