Description

This disclosure relates to a respiratory interface, and more particularly to a respiratory patient interface for providing gas or fluid to a patient. Respiratory support devices are used to deliver gas flows to users or patients in various settings, such as hospitals, medical facilities, home care, or home environments. Respiratory support devices or respiratory therapy devices (collectively, “respiratory devices” or “respiratory apparatus”) may be used to deliver gas flows, such as air and/or supplemental oxygen or other gases, to the user. To deliver heated and humidified gases, respiratory devices may also include humidifiers. Respiratory devices may allow for adjustment and control of gas flow characteristics, including flow rate, temperature, gas concentration, humidity, and pressure. Sensors, such as flow sensors and/or pressure sensors, are used to measure gas flow characteristics. A schematic representation of the respiratory support device is shown.This shows the respiration interface on the patient.This is a front perspective view of one component of a respiratory interface.Figure 2 is a rear perspective view of the respiratory interface.Figure 2 is a top view of the respiratory interface.Figure 2 is a bottom view of the respiratory interface.Figure 2 is an upper perspective view of the cuff and sliding member of the respiratory interface.Figure 6 is a bottom perspective view of the cuff and sliding member.Figure 2 is a front view of the respiratory interface.Figure 2 is an exploded view of the respiratory interface.Figure 2 is a cross-sectional view of the respiratory interface.Figure 2 is a frontal perspective view of the nasal prongs of the respiratory interface.Figure 2 is a cross-sectional view of the nasal prongs of the respiratory interface.Figure 2 is a cross-sectional view of the nasal prongs of the respiratory interface.Figure 2 shows another cross-sectional view of the nasal prongs of the respiratory interface.A posterior perspective view of the nasal prongs.Figure 11A is a top view of the nasal prongs.Figure 11A is a bottom view of the nasal prongs.Figure 11A is a side view of the nasal prongs.Figure 11A is a frontal or posterior view of the nasal prongs.A series of top views showing pivotable prongs.This is a front perspective view of another configuration of the respiratory interface.Figure 17 is a rear perspective view of the respiratory interface.Figure 17 is a top view of the respiratory interface.Figure 17 is a bottom view of the respiratory interface.Figure 17 is a left side view of the respiratory interface.Figure 17 is a right side view of the respiratory interface.Figure 17 is a front view of the respiratory interface.Figure 17 is a rear view of the respiratory interface.Figure 17 is an exploded view of the respiratory interface.Figure 17 is a frontal perspective view of the nasal prongs of the respiratory interface.Figure 26 is a posterior perspective view of the nasal prongs.Figure 26 is a top view of the nasal prongs.Figure 26 is a bottom view of the nasal prongs.Figure 26 is a left-side view of the nasal prong.Figure 26 is a front view of the nasal prongs.Figure 26 is a posterior view of the nasal prongs.This is a front perspective view of another configuration of the respiratory interface.Figure 33 is a rear perspective view of the respiratory interface.Figure 33 is a top view of the respiratory interface.Figure 33 is a bottom view of the respiratory interface.Figure 33 is a front view of the respiratory interface.Figure 33 is a rear view of the respiratory interface.Figure 33 is an exploded view of the respiratory interface.Figure 33 is a frontal perspective view of the nasal prongs of the respiratory interface.Figure 40 is a posterior perspective view of the nasal prongs.Figure 40 is a top view of the nasal prongs.Figure 40 is a bottom view of the nasal prongs.Figure 40 is a left-side view of the nasal prong.Figure 40 is a front view of the nasal prongs.Figure 40 is a posterior view of the nasal prongs.Figure 33 is a front perspective view of the cuff of the respiratory interface.Figure 47 is a rear perspective view of the cuff.Figure 47 is a rear perspective view of the cuff.This is a partial front perspective view of another component of the respiratory interface.Figure 50 is a detailed front perspective view of the respiratory interface.Figure 50 is a top view of the respiratory interface.Figure 50 is another front perspective view of the respiratory interface.This is a schematic diagram of another configuration of the respiratory interface.A series of schematic diagrams of alternative configurations for the respiratory interface are shown.This is a schematic diagram of another configuration of the respiratory interface.This graph shows the test results of a flow supplied at 60 LPM, comparing a standard breathing interface with two nasal prongs with the breathing interface according to the present invention.This shows the streamlines of the exhaled airflow through a
