摘要：
The device has a face cover, a mouth-and-nose mask, and fasteners for holding the face cover on the face. The face cover is provided with a flexible gasket surrounding the eyes, a sea means at its periphery, and a closable coupling to a filtered gas feed. The mouth-and-nose mask, placed inside the face cover, is fitted with a demand regulator and with a direct exhaust to atmosphere. The breathe-in and breathe-out paths are separated by cases.
