Snow Burial Survival Mask
摘要:
A snow burial survival mask has an exhaust tube connected to a headgear. An intake port of the exhaust tube is positioned adjacent to a breathing portion of the headgear in order to intake exhaled carbon dioxide (CO2)-rich air. An air pump connected to the exhaust tube pump the exhaled air from the intake port to an exhaust port away from the user's face, extending survival time in a snow burial situation. At least one burial detection sensor such as a motion sensor, light sensor and/or CO2 sensor is configured to activate the air pump based on detection of a burial event.
