Title: TRACHEAL TUBE WITH CONNECTOR INSERT
Abstract:
A tracheal tube assembly (10) includes a connector body (28), a cannula (14) extending from the connector body, and an insert (24) that provides rigidity to the connector body and retains the cannula in the connector body. The cannula has a tapered upper end (48) that fits between conforming tapered sections (58,44) of the connector body inner surface and the insert. The insert may include features (40) to prevent rotation of the cannula as well as rotation of the insert in the connector body. Features (34, 54) of the insert and connector body may also interface to mechanically retain the insert in the connector body. Different sizes of cannula may be accommodated by different inserts, while using the same or different connector bodies.
