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, and headgear.

Claims

1. A feed tube adapted for use in a ventilation interface comprising:

the feed tube having an annular sleeve with a first exterior portion and a second exterior portion;

the first exterior portion including a plurality of first ribs and a second exterior portion including a plurality of second ribs.

2. The feed tube adapted for use in a ventilation interface according to claim 1, wherein the first exterior portion provides a shorter distance between each first rib;

and

the second exterior portion provides a substantially larger distance between each second rib.

3. The feed tube adapted for use in a ventilation interface according to claim 1, wherein a distance between the first ribs and second ribs is substantially equal.

4. The ventilation interface according to claim 2 further comprising:

means for bending the feed tube without decreasing a cross-sectional area at bending points.

5. The ventilation interface adapted to be inserted into a nares according to claim 4 further comprising:

means for holding the nasal insert in the nares of the user.
