Medico-surgical tubes,cuffs and their manufacture

摘要

An inflatable sealing cuff (10) for a tracheal tube (1) is made from a tubular member (40) having a central region 43 along its length that is thicker than its end regions (41) and (42). The tubular member 40 is placed in a blow moulding cavity (50) and its central region (43) is radially expanded thereby reducing its wall thickness so that the final product has a more constant wall thickness along its length.
