Respiratory device

A valve for use for a respiration system blending at least two gases sources, comprising:

• a valve adapted to:
• (a) be disposed upstream of a patient delivery device selected from the group comprising a mask, mouthpiece, nasal inlet, and combinations thereof, and (b) control at least a portion of a breathable gas source upstream of said patient delivery device and said source comprising both:
• (i) a first gas source and (ii) a second gas source;
• said valve comprises:
• a rotatable first rotation member, said first rotation member upon rotation causes movement of first gear teeth and a movement of a first valve body providing adjustment of gas flow through a first flow path of said first valve body;
• and
• second gear teeth engaging said first gear teeth and movable in response to movement thereof;
• a second valve body movable in response to movement of said second gear teeth;
• wherein movement of said first rotation member causes simultaneous movement of:
• (a) said first valve body, and (b) said second valve body providing adjustment of gas flow through a second flow path;
• wherein said first gear teeth are in an arc around at least a portion of a first rotatable gear wherein said second gear teeth is in an arc around at least an outer portion of a second rotatable gear, and wherein said first rotatable gear is a ring gear with said first gear teeth along an inner portion thereof and engaging said second teeth on an outer portion of said second rotatable gear.

• (i) a first gas source and (ii) a second gas source;
• said valve comprises:
• a rotatable first rotation member, said first rotation member upon rotation causes movement of first gear teeth and a movement of a first valve body providing adjustment of gas flow through a first flow path of said first valve body;
• and
• second gear teeth engaging said first gear teeth and movable in response to movement thereof;
• a second valve body movable in response to movement of said second gear teeth;
• wherein movement of said first rotation member causes simultaneous movement of:
• (a) said first valve body, and (b) said second valve body providing adjustment of gas flow through a second flow path, and wherein said first valve body has at least two distinct and different sized apertures providing two different first flow rates.

• said valve comprises:
• a rotatable first rotation member, said first rotation member upon rotation causes movement of first gear teeth and a movement of a first valve body providing adjustment of gas flow through a first flow path of said first valve body;
• and
• second gear teeth engaging said first gear teeth and movable in response to movement thereof;
• a second valve body movable in response to movement of said second gear teeth;
• wherein movement of said first rotation member causes simultaneous movement of:
• (a) said first valve body, and (b) said second valve body providing adjustment of gas flow through a second flow path, and wherein said first valve body and second valve body have the same axis of rotation.

A valve and flow generator combination device for use with a compressed breathable gas source, comprising:

• a gas flow path adapted to deliver gas from the compressed breathable gas source to a patient delivery device;
• and
• a gas connector operably attached to the compressed breathable gas source;
• a valve body operably located downstream of the gas connector and configured to selectively control a gas flow rate through the gas path downstream of the valve body comprising at least a first aperture and a second aperture, wherein the valve body comprises:
• a gear including an inner gear engaging with an inner surface of an outer ring gear;
• wherein the valve body is selectively movable between at least a first position placing the first aperture within the gas flow path and a second position placing the second aperture within the gas flow path;
• and
• wherein in the first position the gas flow rate is a first flow rate, in the second position the gas flow rate is a second flow rate lower than the first flow rate.
