Patent ID: 8720445

Claim:
A tracheal tube device comprising: a) an elongated tubular element having: i) a distal region configured for placement to access the trachea of a subject; ii) a proximal region, wherein the distal region and the proximal region are portions of the same elongated tubular element; and iii) a longitudinal axis extending from the distal region to the proximal region; b) a CO 2 indicator present on an inner surface of said elongated tubular element at said proximal region and integrated into the tubular element; and c) a removable sterilization barrier, wherein the removable sterilization barrier is a film that has a major extension from a proximal end to a distal end of the CO 2 indicator along the longitudinal axis and selectively seals the CO 2 indicator from the remainder of the tracheal tube device and is configured to be removed from the tracheal tube device before the device is used to intubate a subject without removing the CO 2 indicator.
