Abstract
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.
Claims20
A snow burial mask comprising:
- a) a headgear including a breathing portion below a nose portion of a user and adjacent to a mouth portion of the user;
- b) an exhaust tube including:
- an intake tube portion connected to the headgear and positioned adjacently to the breathing portion;
- an intake port traversing into the intake tube portion;
- an exhaust tube portion;
- and
- an exhaust port connected to the exhaust tube portion, wherein the exhaust tube portion is opposite to a face of the user terminating into the exhaust port opposite the face of the user;
- c) at least one burial sensor;
- d) an air pump fluidly connected to the exhaust tube wherein the air pump is activated by the at least one burial sensor and adapted to force air away from the breathing portion and opposite the face of the user;
- and
- e) a power source and a processing unit operatively connected to the at least one burial sensor and the air pump;
- wherein
- the exhaust port is a free end that can be repositioned next to a part of the user based on a length of the exhaust tube portion, a distance between the exhaust port and the air pump is greater than a distance between the intake port and the air pump.

- b) an exhaust tube including:
- an intake tube portion connected to the headgear and positioned adjacently to the breathing portion;
- an intake port traversing into the intake tube portion;
- an exhaust tube portion;
- and
- an exhaust port connected to the exhaust tube portion, wherein the exhaust tube portion is opposite to a face of the user terminating into the exhaust port to be placed along a back of the user;
- c) at least one burial sensor including at least one of a motion sensor, a light sensor, an acceleration sensor, and a CO2 sensor;
- d) an air pump fluidly connected to the exhaust tube wherein the air pump is activated by the at least one burial sensor, adapted to force air away from the breathing portion and opposite a face of the user and further adapted to draw CO2 away from an airway of the user and deposit said CO2 opposite the face of the user through the exhaust port;
- and
- e) a power source operatively connected to the at least one burial sensor and the air pump;
- wherein
- the exhaust port is a free end that can be repositioned next to a part of the user based on a length of the exhaust tube portion, a distance between the exhaust port and the air pump is greater than a distance between the intake port and the air pump.
