Abstract
A cuff type indwelling device such as a tracheal tube, catheter or the like is provided with a cuff balloon and a pilot balloon of full volume non-stretchable, non-resilient flexible material, and means for inflating both balloons. The pilot balloon is of generally spherical shape when expanded and is enclosed in a longer pressure monitoring balloon of resilient stretchable material. As the drum shaped pilot balloon progressively increases in diameter, during application of pressure, it progressively changes the configuration of the pressure monitoring balloon from elongated cylindrical shape, to oval shape, to substantially spherical shape, thereby visually indicating to the surgeon low side cuff pressure, medium cuff pressure, and high side cuff pressure.
