Nasal interface including ventilation insert
First Claim
1. A ventilation insert of a ventilation interface to be inserted into a nares of a user of the ventilation interface, comprising:
- a cannula connectable to a source of ventilation gas;
a nasal insert adapted to be inserted into a first naris of the nares of the user, the nasal insert forming a portion of an input gas flow passage from the cannula to a distal end of the nasal insert for supplying the ventilation gas to the user;
a seal portion adapted to engage a portion of the first naris, the seal portion provided adjacent the distal end; and
a gas output forming a portion of an output gas flow passage from the nasal insert to an exterior of the ventilation interface for channeling a gas expired by the user, wherein at least a portion of the input gas flow passage and at least a portion of the output gas flow passage are configured to produce laminar flow for the gas passing therethrough when the nasal insert is inserted into the first naris.

Abstract
A ventilation interface to be inserted into a nares of a user of the ventilation interface. A ventilation insert includes a cannula connectable to a source of ventilation gas. A nasal insert adapted to be inserted into a first naris of the nares of the user forms a portion of an input gas flow passage from the cannula to a distal end of the nasal insert for supplying the ventilation gas to the user. A seal portion is adapted to engage a portion of the first naris, the seal portion provided adjacent the distal end. A gas output forms a portion of an output gas flow passage from the nasal insert to an exterior of the ventilation interface for channeling a gas expired by the user. At least a portion of the input gas flow passage and at least a portion of the output gas flow passage are configured to produce laminar flow for the gas passing therethrough when the nasal insert is inserted into the first naris.

24. A ventilation insert of a ventilation interface to be inserted into a nares of a user of the ventilation interface, comprising:
-
a cannula connectable to a source of ventilation gas;
a nasal insert means for forming an input gas flow passage for the ventilation gas from the cannula to a first naris of the nares of the user;
a sealing means for engaging a portion of the first naris; and
a gas output means for forming an output gas flow passage for gas expired by the user from the nasal insert means to an exterior of the ventilation interface, wherein at least a portion of the input gas flow passage and at least a portion of the output gas flow passage are configured to produce laminar flow for the gas passing therethrough when the nasal insert means is inserted into the first naris. - View Dependent Claims (25)
