    • A tracheostomy tube assembly includes a flexible tube (1, 1′) and a flexible introducer (2, 2′) within the tube, the introducer having a passage (22) along its length for receiving a guidewire (9) inserted into the trachea (7) through a tracheostomy (6). The tube (1) has an inwardly-projecting collar (17, 17′) at its patient end (11), which engages an outwardly-projecting shoulder (24, 24′) on the introducer (2, 2′) so that the tube does not ride rearwardly along the introducer during insertion. The flexibility of the assembly is such that it can be inserted through the tracheostomy (6) while straight and then curves to follow the guidewire (9) as its patient end enters the trachea (7).
    • 气管切开管组件包括在管内的柔性管(1,1')和柔性引导器(2,2'),导引器具有沿其长度的通道(22),用于接收插入气管中的导丝(9) (7)通过气管切开术(6)。 管(1)在其患者端(11)处具有向内突出的套环(17,17'),其接合导引器(2,2')上的向外突出的肩部(24,24'),使得 插管时,导管不会沿导引器向后滑动。 组装的灵活性使得其可以通过气管造口术(6)插入,同时直线,然后在患者端进入气管(7)时曲线以跟随导丝(9)。
