Abstract

Claims (33)

1. A respiratory access assembly, comprising:

a movable manifold having at least one opening, the opening in communication with an artificial airway of a patient;

a closed suction catheter assembly comprising at least a connecting end having an opening formed therethrough, a suction catheter, and a sleeve positioned over the suction catheter;

a flap positioned adjacent the closed suction catheter assembly, the flap movable into an opened position permitting passage of the suction catheter into the artificial airway and the flap movable into a closed position that does not permit passage of the suction catheter into the artificial airway;

a shuttle movable between the opening in the manifold and the opening in the connecting end of the closed suction catheter assembly, the shuttle having an opening to permit passage of the suction catheter therethrough, said shuttle configured to move into a locked and unlocked position relative to the manifold;

an actuator for moving the shuttle assembly into the locked position and the unlocked position, wherein the actuator is a rotator which is positioned over at least a portion of the shuttle and is movably coupled thereto;

wherein said locked position prevents movement of said manifold and permits opening of said flap and wherein said unlocked position allows movement of said manifold and prevents opening of said flap; and

wherein the shuttle includes a first groove and the rotator includes a pin which engages the first groove to move the shuttle upon rotation of the rotator.

2. The respiratory access assembly of claim 1 , further comprising a distal connector positioned at least partially over the cuff of the manifold and a distal end of the shuttle.

3. The respiratory access assembly of claim 2 , wherein the shuttle includes end grooves and the distal connector includes pins which engage the end grooves to move the shuttle and the manifold into a locked position relative to each other.

4. A respiratory access assembly, comprising:

a movable manifold having at least one opening, the opening in communication with an artificial airway of a patient;

a closed suction catheter assembly comprising at least a connecting end having an opening formed therethrough, a suction catheter, and a sleeve positioned over the suction catheter;

a flap positioned adjacent the closed suction catheter assembly, the flap movable into an opened position permitting passage of the suction catheter into the artificial airway and the flap movable into a closed position that does not permit passage of the suction catheter into the artificial airway;

a shuttle movable between the opening in the manifold and the opening in the connecting end of the closed suction catheter assembly, the shuttle having an opening to permit passage of the suction catheter therethrough, said shuttle configured to move into a locked and unlocked position relative to the manifold;

an actuator for moving the shuttle assembly into the locked position and the unlocked position;

wherein said locked position prevents movement of said manifold and permits opening of said flap and wherein said unlocked position allows movement of said manifold and prevents opening of said flap; and

a proximal connector which is positioned over a portion of the shuttle, wherein at least a portion of the flap is positioned within the proximal connector.

5. The respiratory access assembly of claim 4 , wherein the portion of the shuttle moves the flap against a portion of the proximal connector in order to position the flap across the opening of the shuttle.

6. A method of using a respiratory access assembly, comprising:

a providing a respiratory access assembly comprising

a movable manifold having at least one opening, the opening in communication with an artificial airway of a patient;

a closed suction catheter assembly comprising at least a connecting end having an opening formed therethrough, a suction catheter, and a sleeve positioned over the suction catheter;

a shuttle movable between the opening in the manifold and the opening in the connecting end of the closed suction catheter assembly, the shuttle having an opening therethrough and configured to move into a locked and unlocked position relative to the manifold;

an actuator for moving the shuttle assembly into the coupled and released position; and

a flap positioned adjacent the shuttle and the closed suction catheter assembly, the flap movable into an opened position permitting passage of the suction catheter into an artificial airway when the shuttle is in a locked position, and the flap movable into a closed position preventing passage of the suction catheter through the shuttle when the shuttle is an un-locked position;

moving the actuator to simultaneously a) move the shuttle distally to engage and lock to the manifold to permit access through the opening in the manifold and b) move the shuttle away from the end connector of the closed suction catheter assembly such that the flap is positioned in an opened position;

moving the suction catheter through the end connector, the shuttle, and the manifold such that the suction catheter is positioned in an artificial airway;

suctioning secretions from at least a portion of a patient's respiratory tract and artificial airway;

withdrawing the suction catheter from the suction catheter pathway and positioning the suction catheter in its sleeve;

moving the actuator to move the shuttle proximally to simultaneously a) disengage from the manifold and move into an unlocked position such that the manifold is movable, and b) move the shuttle toward the end connector of the closed suction catheter assembly such that a portion of the shuttle moves the flap into a closed position thereby blocking and preventing access thereto by the suction catheter.

7. The method of claim 6 , wherein in the step of moving the actuator to move the shuttle distally, the step includes rotating the actuator.

8. The method of claim 6 , wherein in the step of moving the actuator to move the shuttle proximally, the step includes rotating the actuator.
