Title:
EXPIRATORY METABOLISM MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/178752
Kind Code:
A1
Abstract:
An expiratory metabolism measurement system, comprising: an organic steam micro-injection module (1), an aspirator pump (32), a monomer expiratory trace sampling module (36), an aerosol nozzle (311), an air electromagnetic valve (35), a zero-level air purifier (42), and an automatic solvent desorption module (2). A first end of the aspirator pump (32) is connected to an exit port of the organic steam micro-injection module (1), and a second end of the aspirator pump (32) is connected to a first end of a liner tube (33); an air outlet of the monomer expiratory trace sampling module (36) is connected to a second end of the liner tube (33), and a stirrer adsorption and extraction bar is provided in the liner tube (33) to sample the expiratory trace of an experimental animal; an air outlet of the monomer expiratory trace sampling module (36) is connected to a nozzle interface of the aerosol nozzle (311), and an air inlet thereof is connected to an air outlet of the zero-level air purifier (42); the air electromagnetic valve (35) controls zero-level air to enter the monomer expiratory trace sampling module (36) and synchronously prevents an inhalation exposure substance from entering into the monomer expiratory trace sampling module (36); and the automatic solvent desorption module (2) is used for detecting the expiratory metabolite acquired by the stirrer adsorption and extraction bar.
