Abstract
An emergency breathing device including a hood having use and storage configurations, which when compactly wrapped proximate to an oxygen control device for storage is recoverable for use. In use configuration, the hood is capable of being worn upon a user's head, which substantially surrounds the user's head. Hood surface beneath the user's head includes an opening lined with elastic material, which forms a seal about the user's neck at the opening when the hood is donned. An oxygen control device connected to a hood includes a valve body, an actuator, and an oxygen bottle. The valve body provides airflow communication with the interior of the hood, and the oxygen control device is connected to a plumbed breathable oxygen supply through a plumbed source disconnect means removably connected to the valve body. When connected, the oxygen control device permits airflow from the plumbed breathable oxygen supply and valve body to the interior of the hood. A cam within the valve body rotates with the operation of the actuator for engaging a piercing member to pierce the oxygen bottle, causing oxygen to flow from the oxygen bottle to the interior of the hood and forcing the plumbed source…
