Animal chronic obstructive disease test device and method capable of recycling smoke

Abstract

An animal chronic obstructive disease test device capable of recycling smoke, which comprises an animal activity chamber, the top of the animal activity chamber is communicated with an outlet of a smoke preparation box through a smoke supply pipeline, the smoke preparation box is provided with four inlets, three inlets are connected with an O2 supply device, a CO2 supply device and a CO supply device respectively; the lower part of the animal activity chamber is communicated with the fourth inlet of the smoke preparation box through a recirculation pipeline with a recirculation valve, a component measuring device, a manual valve, a fan and a flow meter are arranged on the smoke supply pipeline, and a concentration meter is arranged in the animal activity chamber. The invention further provides a test method based on the animal chronic obstructive disease test device capable of recycling smoke, the smoke composition, concentration, temperature, humidity and the like in the animal activity chamber in the whole test process can be effectively monitored, meanwhile, cigarette smoke is recycled, and operation of a smoke generator is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical test equipment, and in particular relates to an animal chronic obstructive disease test device and method for smog recycling. Background technique [0002] Using cigarette smoke to conduct animal chronic obstructive disease tests is a routine medical research test. There are problems in the existing devices that the cigarette smoke cannot be fully utilized, the moisture in the cigarette smoke is large, and it is easy to spread to the external environment. [0003] The applicant submitted a patent application on 2021-03-01 entitled: A New Animal Chronic Obstructive Disease Experimental Model Device, with the application number: 202120438339.5, which effectively solved the above problems. [0004] The applicant found in follow-up tests that the above-mentioned patents did not pay attention to the specific environmental requirements for animal activities (such as smoke concentration, temperature and ...
