Abstract
A ventilation or CPAP interface system adapted to be inserted into a nares of a user to secure the interface. A cannula adapted to be connected to a source of ventilation gas forms a first portion of an input gas flow passage to supply the ventilation gas to the user. A nasal insert adapted to be inserted the nares of the user forms a second portion of the input gas flow passage from the cannula to a distal end of the nasal insert. A seal portion adapted to engage a portion of the first naris is provided adjacent the distal end of the nasal insert. Ventilation interface system may optionally include feed tubes, y-connector, tube holder, headgear and a headgear flange.
Claims25
A ventilation interface, comprising:
- a cannula with at least one nasal insert and at least one exhaust port;
- the cannula forming a first portion of an input gas flow passage to supply the ventilation gas to the user, the first portion of the input gas flow passage defined by a first passage disposed at a first distal end of the cannula where the cannula is connected to a first source of ventilation gas and a second passage disposed at a second distal end of the cannula where the cannula is connected to a second source of ventilation gas;
- the at least one nasal insert forming second and third portions of the input gas flow passage from the cannula to a distal end of the nasal insert that are substantially axially aligned with the first passage disposed at the first distal end of the cannula where the cannula is connected to a first source of ventilation gas and the second passage disposed at the second distal end of the cannula where the cannula is connected to the second source of ventilation gas;
- a seal portion configured to engage at least a portion of the nares, the seal portion being provided on the distal end of the at least one nasal insert;
- and
- at least one headgear flange disposed the cannula body.
A ventilation or CPAP interface system, comprising:
- a cannula, nasal inserts, seal portions and exhaust ports;
- a first feed tube, a second feed tube and a Y-connector;
- a tubing connector;
- head gear;
- the cannula is adapted to be connected to the first feed tube, second feed tube and Y-connector, the cannula forming a first portion of an input gas flow passage, the first portion of the input gas flow passage defined by a first passage that connects to the first feed tube and a second passage that connects to a second feed tube;
- the first passage and the second passage of the input gas flow passage being substantially axially aligned with the nasal inserts;
- the nasal inserts form a second portion of the input gas flow passage from the cannula to a distal end of the nasal inserts;
- and
- a seal portion adapted to engage at least a portion of the nares, the seal portion provided adjacent a distal end of the nasal insert.
