Method and device for non-invasive ventilation with nasal interface
First Claim
Patent Images
1. A nasal ventilation interface for the purpose of supplying ventilation gas to a person'"'"'s airway, the interface comprising:
- a generally tubular construction with a distal end configured with a first and a second tube for engagement with a person'"'"'s nostrils and each defining an angulated fenestration in alignment with and directly opposed to a nostril opening, the angulated fenestration being diagonally oriented with respect to a person'"'"'s face to define a nostril airflow direction outward from the face and downward from the nostril, a proximal end configured for attachment to a ventilation gas supply hose;
a coupler connecting the first and second distal ends of the tubes; and
a lifting device applied substantially directly under the nose to the distal end of the first and second tubes, wherein the lift creates and maintains an upward engagement force between the respective first and second distal ends of the tubes and the nostrils, and maintains the angulated fenestration oriented along the nostril airflow direction.

Abstract
A nasal ventilation interface including a pair of tubes configured to deliver a ventilation gas. The tubes are attachable at a first end to a ventilation gas supply hose and engageable at a second end with a person'"'"'s nostril. A coupler is configured to align the pair of tubes with the person'"'"'s nostrils, wherein each tube has an absence of pneumatic interconnection with the other tube.

8. A nasal ventilation interface apparatus for the purpose of supplying ventilation gas to a person'"'"'s airway, the apparatus comprising:
- a generally tubular construction with a distal end comprising a first and second tube configured to engage a person'"'"'s nostrils and each defining an angulated fenestration in alignment with and directly opposed to a nostril opening, the angulated fenestration being diagonally oriented with respect to a person'"'"'s face to define a nostril airflow direction outward from the face and downward from the nostril, and a proximal end configured to attach to a ventilation gas supply hose, wherein the distal end comprises a facial pad positioned between the tubes and skin between the user'"'"'s nose and upper lip, and wherein the facial pad cushions the user'"'"'s shin and tilts the distal end of the tubes to maintain the angulated fenestration oriented along the nostril airflow direction and align each of the first tube and the second tube with a rim of the user'"'"'s nostrils.

14. A nasal ventilation interface apparatus for the purpose of supplying ventilation gas to a person'"'"'s airway comprising:
-
a generally tubular construction with a distal end comprising a first and a second tube configured to engage a person'"'"'s nostrils and each defining an angulated fenestration in alignment with and directly opposed to a nostril opening, the angulated fenestration being diagonally oriented with respect to a person'"'"'s face to define a nostril airflow direction outward from the face and downward from the nostril, and a proximal end configured to attach to a ventilation gas supply hose, a band member substantially circumventing the head from the chin to the top of the head, wherein the band member applies upward compression on the chin so as to bias the mouth in a close state, and a first connector between the first tube and the band member and a second connector between the second tube and the band member, wherein the first connector and the second connector apply an upward lifting force on distal ends of the first tube and the second tube to maintain a seal with the nostrils, and maintain the angulated fenestration oriented along the nostril airflow direction. - View Dependent Claims (15, 16, 17)
