ABSTRACT:
This invention relates to a new and improved anesthesia delivery system utilized in medical procedures wherein there is minimized build up of carbon dioxide levels in a patient due to a patient re-breathing their own exhaled gases. The anesthesia delivery system comprises a first tubular element hermetically coupled to a source of gas which is inhaled by a patient, and a second tubular element hermetically coupled to a system for expelling gas exhaled from a patient's lungs such that when a patient is intubated with the delivery system, the end of the first tubular element is positioned adjacent the patient's pharynx while the end of the second tubular element is positioned within the patient's trachea. For that portion of the delivery system that is positioned within the mouth and pharynx of a patient, the first tubular element is adjacent the wall of the second tubular element while the portion of the first and second tubular element structure that is outside the body of a patient has the first tubular element concentrically positioned within the second tubular element. An inflatable balloon is provided about the exterior of the second tubular element that is positioned within the trachea of a patient when the system is utilized which is capable of being selectively inflated or deflated. Furthermore, a separate hollow tubular structure capable of selectively removing gas from within the second tubular element has one of its ends positioned at a point where the first tubular element is coupled to the second tubular element.
