Abstract
An endotracheal tube for artificial ventilation employs a primary cuff and a secondary cuff for locating and positioning the tube in the trachea of a patient. The secondary cuff employs a balloon sleeve which is located in close proximity to the distal end of the tube. The secondary balloon sleeve is sealed against the tube in a reverse folded configuration. The tube wall includes a number of lumens which may be employed for various auxiliary functions.
