6. The device according to claim 5 , further comprising a liquid adapted to be flushed through the rinse tube and extracted by the suction tube.
7. An airway lavage device comprising:
a liquid chamber for delivery of liquid fbr lavage;
a liquid reservoir connected to the liquid chamber for supplying liquid;
a rinse chamber connected to the liquid chamber;
a rinse tube connected to the rinse chamber and adapted for the deliverance of liquid for lavage of the patient's airway;
a first one way valve disposed between the liquid reservoir and the liquid chamber;
stopvalve between the liquid reservoir and the first one way valve;
a second one way valve disposed between the liquid chamber and the rinse chamber; and
a spring loaded button connected to both the first one way valve and the second one way valve, whereby when the button is not pressed, the first one way valve is open and the second one way valve is closed and when the button is pressed, the first one way valve is closed and the second one way valve is open.
8. The device according to claim 7 , further comprising a liquid adapted to be flushed through the rinse tube.
9. A method of evacuation of secretions in the tracheal pathway of a patient during endotracheal intubation comprising:
providing a device comprising:
a tracheal tube adapted for placement in a patient's airway;
a respiratory tube found within the tracheal tube for mechanical ventilation of the patient's airway
a suction tube found within the tracheal tube for suctioning of the patient's airway;
a liquid chamber for delivery of liquid for lavage;
a liquid source connected to the liquid chamber supplying liquid;
a rinse chamber connected to the liquid chamber;
a rinse tube found within the tracheal tube and adapted for deliverance of liquid for lavage of the patient's airway, the rinse tube connected to the rinse chamber
a first one way valve disposed between the liquid reservoir and the liquid chamber;
a stopvalve between the liquid reservoir and the first one way valve;
a second one way valve disposed between the liquid chamber and the rinse chamber; and
a spring loaded button connected to both the first one way valve and the second one way valve, whereby when the button is not pressed, the first one way valve is open and the second one way valve is closed and when the button is pressed, the first one way valve is closed and the second one way valve is open,
inserting the tracheal tube into a patient's airway for intubation;
sealing the tracheal tube within the trachea of the patient;
ventilating the patient through the respiratory tube for mechanical ventilation of the patient;
pressing the spring loaded button, thereby emptying any contents of the liquid chamber, previously supplied to the liquid chamber by the liquid reservoir, into the rinse chamber;
dousing the tracheal pathway of a patient with the liquid, through the rinse tube for loosening secretions from the tracheal pathway; and
suctioning secretions from the tracheal pathway of a patient through the suction tube.
