Breathing apparatus with multiple breathing channels

An apparatus, comprising:

• a mouth aperture configured to be disposed in fluid communication with a mouth of a user;
• a nasal aperture configured to be disposed in fluid communication with one or both nostrils of the user when the mouth aperture is disposed in fluid communication with the mouth of the user;
• a nasal fluid reservoir configured to be in fluidic communication with the one or both nostrils via the nasal aperture;
• an oral fluid reservoir configured to be in fluidic communication with the mouth of the user via the mouth aperture;
• a septum disposed between the nasal fluid reservoir and the oral fluid reservoir;
• a septal valve disposed within the septum and configured to transition between a septal valve open configuration in which the nasal fluid reservoir is in fluidic communication with the oral fluid reservoir via the septal valve, and a septal valve closed configuration in which fluidic communication between the nasal fluid reservoir and the oral fluid reservoir is substantially prevented via the septal valve, the septal valve being configured to assume the septal valve open configuration in response to oral inhalation or nasal exhalation by the user, and the septal valve closed configuration in response to oral exhalation or nasal inhalation by the user;
• a nasal inhalation valve disposed between the nasal fluid reservoir and an inhalation channel that is configured to be in fluidic communication with a nasal inhalation inlet, and configured to transition between a nasal inhalation valve open configuration in which the nasal fluid reservoir is in fluidic communication with the inhalation channel, and a nasal inhalation valve closed configuration in which fluidic communication between the nasal fluid reservoir and the inhalation channel is substantially prevented;
• an oral inhalation valve disposed between the oral fluid reservoir and the inhalation channel, and configured to transition between an oral inhalation valve open configuration in which the oral fluid reservoir is in fluid communication with the inhalation channel, and an oral inhalation valve closed configuration in which the fluidic communication between the oral fluid reservoir and the inhalation channel is substantially prevented;
• an exhalation valve in fluidic communication with the oral fluid reservoir and configured to transition between an exhalation valve open configuration in which the oral fluid reservoir is in fluidic communication through the exhalation valve to an ambient environment outside the apparatus, and an exhalation valve closed configuration in which fluidic communication between the oral fluid reservoir and the environment through the exhalation valve is substantially prevented;
• the nasal inhalation valve being configured to assume the nasal inhalation valve open configuration in response to nasal inhalation by the user, and the nasal inhalation valve closed configuration in response to nasal exhalation by the user,
• the oral inhalation valve being configured to assume the oral inhalation valve open configuration in response to oral inhalation by the user, and the oral inhalation valve closed configuration in response to oral exhalation by the user,
• the exhalation valve being configured to assume the exhalation valve open configuration in response to oral exhalation by the user, and the exhalation valve closed configuration in response to oral inhalation by the user.
