In view of the defect that the existing devices cannot meet the simultaneous exposure of carbon monoxide and noise, this application provides an experimental device for combined exposure of rats to noise and carbon monoxide. After assembling the noise generating chamber and the gas mixing chamber equipped with Bluetooth speakers, they were embedded in the joint exposure chamber. The rats were placed in the mouth and nose poisoning cup through the door body, and carbon monoxide was passed into the gas mixing chamber through the air inlet; the noise Enter the joint exposure chamber through the sound transmission hole; because the mouth and nose poisoning cup is connected with the joint exposure chamber, the rats in the mouth and nose poisoning cup can be simultaneously exposed to carbon monoxide and noise. This device can meet the experimental requirements of simultaneous exposure to carbon monoxide and noise. In addition, the mouth and nose poisoning cup can restrict the activities of rats, which can not only simulate the real situation of restricted activities of cabin workers, but also make the distance between the rats' ears and noses and noise sources and gas pollution sources basically the same, thereby improving the reliability of experimental results. scientific.
Description
technical field [0001] The invention relates to the field of experimental devices, in particular to an experimental device for rat noise and carbon monoxide combined exposure exposure. Background technique [0002] With the deepening of economicalization, urbanization and industrialization, the human life style and living environment have also undergone tremendous changes. A large number of environmentally harmful factors, such as carbon monoxide and noise, are produced in industrial production, transportation and urban construction. , seriously affecting human health. According to statistics, the average daily traffic noise intensity of residents in 40% of EU countries is about 55dB, and some developing countries even reach 75-80dB; the average traffic noise in most cities in China is mostly 76-81dB, and the industrial noise intensity is mostly in the 85~95dB. Carbon monoxide comes from industrial and mining enterprises, transportation, heating boilers, setting off firewo...
