Abstract

The invention relates to the technical field of environmental aerosol measuring, in particular to a simulated lung breathing device. The device comprises a sealing box, a lung model, an air collectingbag and an air pump, and the lung model and the air collecting bag are both arranged in the sealing box and are kept independent of each other; the lung model is connected with a lung pipeline leading to the outside of the sealing box; the air pump is connected with a suction pipeline, the suction pipeline is provided with a first valve and a second valve, and the first valve, the second valve and the air pump form a series loop; the air collecting bag is communicated with the suction pipeline and is communicated between the first valve and the second valve; the first valve and the second valve are three-way valves, and a valve port of each valve is kept to be communicated with air outside the sealing box; the air pump exhausts air from the air collecting bag, the air collecting bag contracts, the air pressure in the sealing box is reduced, airflow enters the lung model from the lung pipeline, and the inspiration process is completed; the air pump inflates the air collecting bag, theair collecting bag expands, the air pressure in the sealing box is increased, airflow flows out of the lung model along the lung pipeline, and the expiration process is completed.

Description

technical field [0001] The invention relates to the technical field of environmental aerosol measurement, and more specifically, to a simulated lung breathing device. Background technique [0002] In recent years, my country's air pollution has become more and more serious, and severe haze weather has appeared in most areas. The research on human respiratory exposure has also attracted more and more attention. It is hoped that the gas composition and concentration, Particle size and concentration information. At present, there are problems such as high cost, long time, and ethics involved in using human body experiments. In order to more conveniently carry out experimental detection of lung respiration-related data, it is of great significance to study a simple simulated lung respiration device. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a device for simulating lung respiration, which...
