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.
