A bronchial ventilation assembly which enables selective ventilation of a patient's lungs comprises a ventilation device having first and second bronchial tubes 6, 8 for insertion into the left and right bronchi respectively, and a tracheal tube 4 which includes first and second tracheal tube sections which communicate with the first and second bronchial tubes respectively. The configuration of the device can be changed between an in-use configuration in which bronchial tubes splay outwardly as shown, and an insertion configuration in which the bronchial tubes are closed together for insertion of the device into a patient's trachea. The assembly includes an insertion instrument for changing the configuration of the device between its in-use configuration and its insertion configuration. This instrument may be a sleeve 40 slidable along the tube 4 to hold the bronchial tubes together against their resilient tendency to splay apart, during insertion. Alternatively, it may comprise a drawstring, Figures 5 and 6. |
