摘要

The breathing apparatus, typically configured as a breathing pipe, has two separated compartments so that a user inhaling through the mouthpiece causes fan blades in one compartment to rotate on a shaft which is drivingly connected to a shaft and fan blades in the other compartment so as to cause an air with an active substance to be delivered in the vicinity of the user's nostrils. This is stated to have a calming effect on a user.
