Abstract
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.
Claims19
A patient interface assembly comprising:
- a patient interface;
- an interface tube;
- and
- a connector comprising:
- a proximal portion connectable to the interface tube;
- a distal portion comprising an inner wall, an outer wall, and a gap between the inner wall and the outer wall;
- the inner wall being generally cylindrical, and the outer wall being generally cylindrical but tapering along at least a portion of its length such that a proximal portion of the outer wall has a larger outer diameter than a terminal end of the outer wall, wherein the gap between the inner wall and the outer wall extends from at least the proximal portion of the outer wall to the terminal end of the outer wall;
- and
- the outer wall configured as a first connection mechanism, wherein the first connection mechanism comprises a first male connector, and wherein an inner surface of the outer wall includes an annular recess.
A patient interface assembly comprising:
- a patient interface;
- an interface tube;
- and
- a connector comprising:
