Abstract
A tracheal and pharyngeal suction device includes a handle including an interior cavity within the handle body, a connector positioned within the interior cavity and moveable along at least a portion of a length of the interior cavity, a proximal suction catheter having a coupling portion and a treatment portion, wherein the coupling portion is coupled to a proximal side of the connector; and a distal suction catheter coupled to a distal side of the connector.
Claims20
A tracheal and pharyngeal suction device comprising:
- a handle comprising an interior cavity within the handle and an actuator comprising a proximal side and a distal side positioned at least partially along an outer surface of the handle;
- a connector positioned within the interior cavity and moveable along at least a portion of a length of the interior cavity between a retracted position and an extended position;
- a proximal suction catheter having a coupling portion and a treatment portion, wherein the coupling portion is coupled to a proximal side of the connector;
- and
- a distal suction catheter coupled to a distal side of the connector;
- wherein the treatment portion of the proximal suction catheter extends beyond a proximal end of the handle when the connector is in the extended position;
- wherein the proximal suction catheter and the distal suction catheter are separate components;
- wherein the actuator is coupled with the connector and is configured to cause the connector to translate between the retracted position and the extended position;
- and
- wherein a duct extends through the proximal side of the actuator between a hollow interior of the connector and the atmosphere surrounding the handle, and the duct comprises a duct opening that is limited to the proximal side of the actuator.

A method of using a tracheal and pharyngeal suction device that comprises a handle;
- a connector moveable along at least a portion of a length of an interior cavity in the handle and including an actuator comprising a proximal side and a distal side positioned on an outer surface of the handle;
- a duct extending through the proximal side of the actuator between a hollow interior of the connector and the atmosphere surrounding the handle, wherein the duct comprises a duct opening that is limited to the proximal side of the actuator;
- a proximal suction catheter having a treatment portion and a coupling portion, wherein the coupling portion is coupled to a proximal side of the connector;
- and a distal suction catheter coupled to a distal side of the connector, wherein the proximal suction catheter and the distal suction catheter are separate components, the method comprising:
- inserting the handle into a patient's mouth;
- extending at least the treatment portion of the proximal suction catheter beyond a proximal end of the handle to a desired distance within a patient's throat by applying a pressure to the distal side of the actuator as the duct opening remains uncovered to move the actuator along the outer surface of the handle;
- covering the duct opening to engage suction through the proximal suction catheter;
- and
- retracting at least the treatment portion of the proximal suction catheter by moving the actuator along the outer surface of the handle as the duct opening remains covered.

A tracheal and pharyngeal suction system comprising:
- a tracheal and pharyngeal suction device comprising:
- a handle comprising an interior cavity within the handle;
- a connector positioned within the interior cavity and moveable along at least a portion of a length of the interior cavity between a retracted position and an extended position;
- a proximal suction catheter having a coupling portion and a treatment portion, wherein the coupling portion is coupled to a proximal side of the connector;
- and
- a distal suction catheter coupled to a distal side of the connector;
- wherein the proximal suction catheter and the distal suction catheter are separate components;
- an oral suction tube coupled to a proximal end of the handle;
- an actuator comprising a proximal side and a distal side positioned along an outer surface of the handle and coupled to the connector, wherein the actuator comprises a duct extending through the proximal side of the actuator between a hollow interior of the connector and the atmosphere surrounding the handle, and the duct comprises a duct opening that is limited to the proximal side of the actuator;
- an adjustable stop configured to adjust a location of the extended position by preventing the actuator from traveling beyond the location of the adjustable stop in a proximal direction of the handle;
- a port coupled to the distal suction catheter;
- a covering coupled to a distal end of the handle and to the port;
- a guard attachable to the oral suction tube to prevent the handle from being inserted too far into a patient's mouth;
- a measurement device;
- and
- an extender attachable to the handle to allow for the proximal suction catheter to be extended different lengths.
