DEFINITION

Classification: 128/205.26

Atmosphere enclosure (e.g., oxygen tent, hyperbaric chamber for pressurizing whole body, etc.):

(under subclass 204.18) Subject matter including means enclosing a portion (e.g., the head) or all of the user's body and providing a breathable atmosphere.

(1) Note. Included in this subclass are devices intended merely for pressurization of the whole body, with no disclosure of a specific breathing apparatus. Since all such devices which enclose the entire body for an extended period of time must supply a breathable atmosphere, they are properly placed in this subclass.
