Non-destructive monitoring system for animal exposure on fire scene

Abstract

The invention discloses a non-destructive monitoring system for animal exposure on a fire scene and relates to the field of animal exposure monitoring. The system comprises an animal exposure box and a set of monitoring device, wherein the monitoring device is used for monitoring a fire environment and behavior characteristics of animals in a smoke exposure process; a gas distributor, thermocouples and two or more homoeothermic animal bins are arranged in the animal exposure box; and a physiological signal monitoring probe is arranged in each homoeothermic animal bin. The system has the advantages that body temperatures of the animals can be kept constant through the homoeothermic animal bins; through the gas distributor, after the smoke enters the animal exposure box, the smoke is quickly and uniformly distributed at the mouths and the noses of the animals, so that inaccurate experimental results caused by inconsistent exposure conditions are avoided; and change of physiological indexes of the animals during fire smoke exposure is monitored in a non-destructive mode through the physiological signal monitoring probes, so that inaccurate experimental results caused by injury of animal bodies due to destructive monitoring are avoided.

Description

technical field [0001] The invention relates to the field of animal exposure and poisoning monitoring, in particular to a non-destructive monitoring system for animal exposure and poisoning at a fire scene. Background technique [0002] Combustibles in a fire will produce a large amount of high temperature, toxic smoke. The dense smoke will cause visual obstacles to personnel escaping. High temperature flue gas can cause thermal injury to people. Inhalation of toxic components in the smoke such as hydrogen cyanide, hydrogen chloride, carbon dioxide, carbon monoxide, etc. will cause the loss of escape ability of the human body and even death. The smoke produced by the fire has the characteristics of high smoke density, rapid change of smoke temperature, and complex toxic components in the smoke. Although there are many reports on the development and use of animal exposure and poisoning devices at present. However, there are few researches on the poisoning of the mixed...

Problems solved by technology

[0004] In addition, the purpose of the fire smoke toxicity animal experiment is to deduce the behavior and pathology of evacuation when the fire occurs from the behavioral performance and physiological indicators of animals exposed to fire smoke. It is not only necessary to test the LD50 value of fire smoke, but also to It is necessary to monitor the behavior and physiological indicators of animals during the exposure process, and the existing poisoning device can only complete the animal inhalation poisoning experiment, which is generally used to test the LD50 value of the poison. Therefore, the existing animal exposure device cannot According to the special requirements of the fire scene, the animal exposure experiment was completed
