Human volatile matter collecting outfit

Abstract

The invention belongs to a human physiological experimental outfit, particularly relates to an outfit for human volatile matter research. The outfit comprises a one-piece airtight outfit and a half-mask respirator, wherein the one-piece airtight outfit is made from airtight materials, the seams and joints are sealed, the one-piece airtight outfit comprises a one-piece loose-fitting suit (7) and a hood, the back side of outfit is provided with a vertical airtight zipper (1) from the hood back to the crotch, the waist of the outfit is provided with a joint nozzle (6) capable of evacuating and inflating the air in the outfit and collecting air samples, and the front of the hood is provided with a transparent face screen (2); and the half-mask respirator comprises an adjustable elastic cord which tightly bonds a mask (3) and the face, an inspiration tube (4) with an inspiration non-return valve, an expiration tube (5) with an expiration non-return valve, and a talker, the inspiration tube (4) and the expiration tube (5) pass through the one-piece airtight outfit. The invention realizes the separation and complete collection of human respiratory gases and body surface volatile gases.

Description

technical field [0001] The invention belongs to a device for human physiological experiments, in particular to a device for research on volatile substances in the human body. Background technique [0002] The volatile components of the human body are relatively complex, and many of them, such as ammonia, indole, methane, carbon monoxide, hydrogen sulfide, etc., are poisonous and harmful to the human body. Since normal people live in an open environment, harmful gases generated in life can be discharged into the atmosphere at any time Therefore, the research work on volatile components excreted from the human body was seldom carried out in China in the past. However, in recent years, with the development of aerospace and navigation, in some special fields such as manned spacecraft and submarines, because personnel need to stay in a closed environment for a long time, the accumulation of volatiles will endanger personnel health, work efficiency and even life safety. It is nec...

AI Technical Summary

Problems solved by technology

The human volatiles experimental chamber made of hard materials is easily deformed and damaged when the pressure difference between the inside and outside reaches a certain level. Therefore, it is impossible to completely drain the air in the chamber before filling it with clean gas, and it is also difficult to remove the chamber after the experiment. Due to the complete collection of human gas volatiles, the error of the experimental system is difficult to control; the experimental cabin also has problems such as the inability to separate human respiratory gas and body surface volatiles, high processing costs, inconvenient and incomplete collection of gas and liquid samples in the cabin, etc. Affect the objectivity and scientificity of experimental data
