<p>An adjustable flange for a tracheostomy tube has a locking assembly (25) with two C shape clamp arms (26) and (27) hinged together at one end (28). A lever (50) with a threaded stem (51) extends through the opposite end of one arm (27) and into a threaded aperture (32) in the other arm (26). When the handle (55) of the lever (50) is inclined out of the plane of the locking assembly (25) it can be slid freely along the tracheostomy tube (1) for positioning. The locking assembly (25) is locked in position by rotating the handle (55) down to lie in the plane of the locking assembly. The flange (20) has two wings (22) and (23) connected with a central plate (20) by webs (42) and (43) of reduced width so that the webs flex to allow the wings to be lifted readily.</p> |
