Abstract
In accordance with at least one exemplary embodiment, a ventilation system for providing gas under a first pressure to the nose of a user and second pressure to the mouth of a user is disclosed. A ventilation system can include a flow generator that can be connected to a gas supply tube. The gas supply tube can be in fluid communication with a ventilation interface. At least a portion of the gas supply tube can have a divider within the channel of the tube forming a nasal passageway and an oral passageway. A nasal breathing chamber and an oral breathing chamber can be defined in the ventilation interface. The nasal breathing chamber can be in fluid communication with the nasal passageway. The oral breathing chamber can be in fluid communication with the oral passageway.
Core Innovation
The invention discloses a ventilation system/interface and a ventilation mask that separates pressurized breathable gas pathways for the nose versus the mouth. A gas supply tube is configured with an internal divider to form nasal and oral passageways or channels, and the passageways feed corresponding nasal and oral breathing chambers in the mask.
The system enables delivering different pressures to the nasal and oral chambers, and valves or other flow/pressure regulation mechanisms are described for controlling the delivered pressure to each chamber. Embodiments include a divided mask port and/or separate CPAP connections.
The disclosure further describes hybrid and full masks having separated internal cavities. The interface includes gas entry ports and gas receiving chambers associated with nasal and oral breathing, and the described separation supports selectively controlled delivery to the user’s nose and mouth through the respective chambers.
Claims Coverage
The partial content identifies three independent claims that center on separating nasal and oral gas receiving chambers and supplying gas from different gas supply devices to those chambers via corresponding entry ports and tubes. Across the independent claims, the inventive features include separate gas entry ports and receiving chambers for nasal versus oral use, fluid separation or non-communication between the chambers, and configurable delivery arrangements that distinguish nasal and oral connections.
Ventilation interface with separate gas entry ports and receiving chambers connected to corresponding gas supply tubes
A ventilation mask includes a ventilation interface having a first gas entry port, at least one second gas entry port, a first gas receiving chamber, and at least one second gas receiving chamber, and includes a first gas supply tube configured to be in fluid communication with a first gas supplying device and at least one second gas supply tube configured to be in fluid communication with a second gas supplying device.
Plurality of gas receiving chambers with nasal and oral chambers supplied by separate entry ports
A ventilation mask includes a plurality of gas receiving chambers including a nasal gas receiving chamber and an oral gas receiving chamber, wherein a first gas entry port is in fluid communication with a first gas supplying device and in fluid communication with the oral gas receiving chamber, and wherein at least one second gas entry port is in fluid communication with a second gas supplying device and in fluid communication with the nasal gas receiving chamber.
Oral and nasal gas entry ports spatially arranged on the ventilation interface feeding respective oral and nasal receiving chambers
A ventilation mask includes a ventilation interface, at least one oral gas entry port, a first nasal gas entry port located on a first side of the at least one oral gas entry port, and a second nasal gas entry port located on a second side of the at least one oral gas entry port, with an oral gas receiving chamber in fluid communication with the oral gas entry port and a nasal gas receiving chamber in fluid communication with at least one of the first nasal gas entry port and the second nasal gas entry port.
Across the independent claims, the claim coverage concentrates on ventilation masks that provide distinct nasal versus oral gas receiving chambers fed via separate gas entry ports and connected supply tubes or devices, with additional separation characteristics addressed by dependent claim limitations referenced in the partial content.
Stated Advantages
Enables delivering different pressures to the nasal and oral chambers.
Documented Applications
Ventilation mask applications with separated nasal and oral breathing chambers for user ventilation.
