CONNECTOR FOR MULTIPLE SIZED CONNECTIONS

摘要

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.

主权项

1. A male end portion for a gases supply conduit connector, the male end portion comprising:
a proximal end and a distal end, the proximal end being configured to connect to a conduit and the distal end being configured to mate with two or more different female end portions; the distal end of the male end portion comprising a first male connector and a second male connector, the first male connector generally encircling the second male connector with a radial gap defined between the first male connector and the second male connector; the first male connector comprising an outer wall that extends distally from a proximal end wall, 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 distal portion of the outer wall; the second male connector comprising an inner wall, the inner wall comprising an outer surface, the outer surface of the inner wall being spaced apart from an inner surface of the outer wall to define a gap between the inner wall and the outer wall.
