Protective bag used in severe environment

Abstract

The invention discloses a protective bag used in a severe environment. Protective clothing and a protective hood which are worn in a matched mode are included. The protective hood comprises an integrally-formed hood, a face mask and a neck connecting portion connected to a bottom of the hood. The neck connecting portion is connected with the protective clothing to form a completely sealed head wearing space. The hood is connected with an oxygen system. A camera system and a voice system are arranged on the face mask. The face mask comprises an eye visual window and a nose and mouth space whichare matched with a face of a human body, a silica gel isolation strip is arranged between the nose and mouth space and the eye visual window, the silica gel isolation strip is arranged on a nose bridge of the human body and is matched with the shape of the nose bridge, and the silica gel isolation strip divides the eye visual window and the nose and mouth space into two relatively isolated spaces. By using the protective bag used in the severe environment, a problem that in the prior art, after rescue and epidemic prevention workers wear isolation equipment, sights are blocked due to an influence of exhaled carbon dioxide and moisture is solved.
