Abstract:
A tracheal tube for placement in a middle or upper tracheal section of a patient, comprising:a high-volume, low-pressure fixing cuff having a shape to block a trachea beneath a glottis of the patient; a respiratory cannula disposed through said fixing cuff; a tampon-bladder disposed concentrically about said cuff, said tampon-bladder being made of flexible material and expansible by the influx of fluid, which when filled is different in shape from the shape of the cuff; said tampon-bladder being made from a material such that a shape-preserving pressure is distributed throughout the subglottic region when said tampon-bladder is in a full condition, said material being a sufficient length so as to occupy the subglottic space completely when said tampon-bladder is in the full condition exerting an epithelium-sparing pressure on subglottic structures.
