Abstract: A tongue cleaning device includes a debris retention feature that helps the user remove debris from the tongue. In one embodiment, the feature is a suction system that removes the debris from the working area of the device. In another embodiment, the feature is a recess positioned adjacent the working edge such that the debris will collect in the recess. Another embodiment of the invention provides a tongue cleaning device having a working edge that is concave with respect to the tongue. Other embodiments of the invention provide flexible handle and head designs.

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.

Abstract: Lightweight hyperbaric chamber capable of maintaining pressures of up to 22 psi greater than ambient through the use of at least two zippers, at least one of which is a sealing zipper, and preferably with heavy fabric and a reinforcing outer layer.

Abstract: A hood suitable for protection against decompression and toxic fumes having a flanged neck seal.

Abstract: A hood suitable for protection against decompression and toxic fumes, prepared using a laminar structure of polyimide, two or more layers of fluoropolymer and heat sealable polymer that affords the heat resistance of polyimide with a markedly lower internal noise level, ease of fabrication and resistance to etching by flame. An improved neck seal is also provided.
