摘要：
A tracheostomy tube has an inflatable sealing cuff (11) towards its patient end (6) and a fluid-permeable cuff (31) mounted on the shaft (1) above the inflatable cuff. The fluid-permeable cuff (31) contains hydrogel granules (32) that absorb moisture in the trachea (T) and help reduces the amount of secretions leaking past the sealing cuff (11). When the tube is to be withdrawn from the trachea (T) the lower, inflatable cuff (11) is deflated allowing the upper, fluid-permeable cuff (31) to be flattened against the outside of the lower cuff.
