Abstract
Intratracheal pulmonary ventilation is introduced to the distal end of an endotracheal tube by one or more intratracheal pulmonary ventilation tubes located in the wall of an endotracheal tube. The direction of flow of the intratracheal pulmonary ventilation is directed away from the distal end of said endotracheal tube, towards the proximal end of said endotracheal tube. The flow through the intratracheal pulmonary ventilation tube reduces the amount of carbon dioxide by replacing the gas located between the distal end of the endotracheal tube and the proximal end of the endotracheal tube where the endotracheal tube is connected to an artificial ventilation system.
Claims14
An endotracheal tube comprising:
- a main tube having an inside, an outside, and proximal and distal ends, said distal end designed to be positioned in the trachea of a patient, said proximal end designed to be attached to a respirator;
- at least one secondary tube having a distal end which terminates substantially adjacent to the distal end of said main tube, said secondary tube substantially parallel to said main tube near said distal end of said main tube;
- at least one opening between said secondary tube and said inside of said main tube located substantially adjacent to the distal end of said secondary tube;
- a tab located on the inside of said main tube between the distal end of said endotracheal tube and the opening between said secondary tube and said main tube, and oriented such that flow through said secondary tube toward the distal end of said secondary tube is directed away from said distal end of said main tube.
An endotracheal tube comprising:
- a main tube having a proximal and a distal end, said distal end designed for insertion into a patient, and preferably positioned in the trachea of the patient, said proximal end designed for attachment to equipment for artificially ventilating the patient in whom the distal end of said main tube is positioned;
- at least one intratracheal pulmonary ventilation tube having a distal end and a proximal end and located within the endotracheal tube, substantially adjacent to, and parallel to said main tube, said distal end of said intratracheal pulmonary ventilation tube located substantially adjacent to said distal end of said main tube, said proximal end of said intratracheal pulmonary ventilation tube extending toward said proximal end of said main tube;
- at least one opening between said intratracheal pulmonary ventilation tube and said main tube near the distal end of said intratracheal pulmonary ventilation tube and said distal end of said main tube;
- a tab located on the inside of said main tube between the distal end of said endotracheal tube and the opening between said intratracheal pulmonary ventilation tube and said main tube, and oriented such that flow through said intratracheal pulmonary ventilation tube toward the distal end of said intratracheal pulmonary ventilation tube is directed away from said distal end of said main tube;
- said opening between said distal end of said intratracheal pulmonary ventilation tube and said distal end of said main tube further comprising a curved section of said intratracheal pulmonary ventilation tube.
