A breathing support system comprises a housing, a plate with a central aperture forming an annular bearing surface and with peripheral air passageways and a cap with a base and a wall slidably extending into the distal region. Air ports have a tubular guide extending proximally from the base. A valve assembly includes a disc formed with a periphery selectively positionable in contact with the bearing surface and passageways and also includes a thin rod with a distal end adjustably received within the guide. A resilient member is positioned between the base and plate urging the base and cap distally and the disc into contact with the bearing surface and passageways. An exhaust valve adapted to allow the exhaling of air is located on an upper radial extent of an intermediate region of the housing. A primary port is adapted to receive and support a bottle of primary medication. |
