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...

Examples

Embodiment 1

[0011] Embodiment 1: referring to accompanying drawing, a kind of human body volatile matter collection suit is characterized in that: it comprises one-piece airtight clothing and independent half mask respirator;

[0012] The one-piece airtight clothing includes one-piece loose-fitting underwear 7 (with an internal volume of 3 to 4 times the volume of a human body) and a hood, which are made of airtight materials, and seams and interfaces are sealed. There is a longitudinal airtight zipper 1 from the back of the hood to the crotch at the back of the body loose-fitting underwear 7, and the waist is provided with a joint nozzle 6 that can carry out gas evacuation, inflation and gas sample collection in the clothing. The front is a transparent screen 2;

[0013] Described half-mask respirator comprises the adjustment elastic band that makes mask 3 and face combine closely, the inhalation pipeline 4 of band inspiratory one-way valve, the exhalation pipeline 5 of band exhalation o...

Embodiment 2

[0014] Embodiment 2: According to the human body volatile collection suit described in Embodiment 1, it also includes suspenders 8 arranged on the waist and head to reduce the weight of the subject's clothing and make it easier for the subject to simulate various actions.

Embodiment 3

[0015] Embodiment 3: In Embodiment 1 or 2, the cloth used in the one-piece airtight garment is thermoplastic polyurethane multilayer composite fabric. The material's low volatility, low adsorption characteristics, and easy cleaning features can reduce the background value of volatile components in clothing and the adsorption of human volatiles, which can further reduce system errors.
