Connector for multiple sized connections
A connector is used to connect a gases supply to a user. The user can be fitted with an interface, such as a cannula, while the gases supply can include a conduit. The connector interfaces between the conduit and the interface. The connector has a female assembly and a male assembly that connect together, such as by push fit. The male assembly includes an inner portion sized and configured to mate with a first female connector and an outer portion sized and configured to alternatively mate with a second female connector.
1. A connector for a gases supply conduit comprising:
a distal portion comprising an inner wall, an outer wall, and a gap between the inner wall and the outer wall;
a proximal end comprising a first catch and a first window, wherein the first catch is generally aligned with the first window; and
the proximal end connectable to an interface tube side of a breathing circuit and the distal portion connectable to another connector.
2. The connector of claim 1 , wherein the first catch is one of a plurality of catches.
3. The connector of claim 2 , wherein the plurality of catches encircle a generally circular passageway at the proximal end.
4. The connector of claim 2 , wherein at least two of the plurality of catches are disposed opposite one another.
5. The connector of claim 1 , wherein the first catch overhangs the first window.
6. The connector of claim 1 , wherein the first catch is provided on a proximal rim supported by two or more posts.
7. The connector of claim 6 wherein the proximal rim is provided on a flange configured for outward deflection.
8. The connector of claim 1 , wherein the outer wall defines a first male connector.
9. The connector of claim 1 , wherein the inner wall defines second male connector.
10. The connector of claim 1 , wherein the outer wall comprises a taper.
11. The connector of claim 1 , wherein the outer wall extends the same distance as the inner wall in an axial direction.
12. The connector of claim 1 , wherein the inner wall comprises an inner surface that defines a passage through the connector.
13. The connector of claim 1 , where in the outer wall is cylindrical.
14. The connector of claim 1 , wherein the outer wall comprises a recess.
15. A patient interface assembly comprising:
a patient interface;
an interface tube;
a connector comprising:
a distal portion comprising an inner wall, an outer wall, and a gap between the inner wall and the outer wall;
a proximal end comprising a first catch and a first window, wherein the first catch is generally aligned with the first window; and
the proximal end connectable to an interface tube side of a breathing circuit and the distal portion connectable to a second connector.
16. The patient interface assembly of claim 15 , wherein the connector is coupled to the distal portion of the interface tube with a mechanical coupler.
17. The patient interface assembly of claim 15 , wherein the patient interface comprises a nasal cannula.
18. The patient interface assembly of claim 15 , wherein the distal portion is connectable to at least two different types or sizes of second connector portions.
19. The patient interface assembly of claim 18 , wherein the second connector portion is provided on a breathing tube that is configured to couple with a humidifier and configured to deliver heated and humidified gases to the patient interface.
