Method and device for measuring harmfulness of passive smoking

Abstract

The invention discloses a method and a device for measuring the harmfulness of passive smoking. A test animal and a rearing cage are arranged in a hermetic contamination cover; a cigarette is ignited, and the mixing gas of the air and the smoke is continuously fed through a gas inlet circuit; the concentration of oxygen, the concentration of carbon monoxide and the concentration of smoke grain phase matters in the contamination cover are maintained relatively constant; and the test animal lives in the contamination cover, the reaction of the test animal is observed, and the quantity of the cigarette smoke grain phase matters sucked by the test animal is calculated to obtain the harmfulness of the smoke passively sucked by the test animal. The invention overcomes the defects that the concentration of the cigarette smoke grain phase matters can not be accurately controlled and measured, and the structure is quite complicated in the prior art, can accurately measure and control the concentration of the cigarette smoke grain phase matters in the cover, and measures the harmfulness of the passive smoking more accurately. Meanwhile, the device is simpler and can be widely applied to the cigarette field.

Description

technical field [0001] The invention relates to a measuring method and device, in particular to a method and device for measuring the harmfulness of passive smoking. Background technique [0002] Smoking, as a living habit with a long history, is an important part of modern people's life. But smoking is harmful to the body is also the formula of the industry. With the improvement of people's living standards, the impact of smoking on people's health has attracted more and more attention. Especially passive smoking, that is, the harm caused by second-hand smoke to the human body cannot be ignored. There are many testing methods for the harmfulness of active smoking, mainly by measuring the relationship between the harmful substances in cigarettes and the state of the smoker, but it is more difficult to measure the harmfulness of passive smoking. This is because cigarette smoke is a complex component, and the harmfulness of various harmful components is unknown; and the tox...

AI Technical Summary

Problems solved by technology

However, the deficiency of this prior art is that the concentration of particulate matter in the cigarette smoke cannot be accurately controlled and measured to determine the hazards of passive smoking due to the fact that the simulated smoking is generated by a negative pressure air pump and the smoke is directly passed into the poisoning tank. Errors and mistakes are prone to occur in nature, and the structure is more complicated
