SCAVENGING APPARATUS FOR LIFE SUPPORT SUIT HELMET

摘要

An apparatus for scavenging vomitus from the interior of the helmet of a life support suit comprises a normally furled mask (10) defined by a sidewall structure (20) connecting to a suction conduit (90). The mask is expanded into registry with the mouth of the user by inflation of bellows (40) located within the sidewall structure. Suction applied to the interior of the mask positively traps vomitus on a liquid absorbent filter (85).
