Abstract

By interposing an adapter between the endotracheal or tracheal tube inserted to a patient and the ventilation and suction systems that are connected to the endotracheal tube, a catheter could be inserted via an input port built into the adapter so as to enable a medical personnel to provide localized treatments in the lungs of a patient without having to disconnect either one of the systems connected to the endotracheal tube. The adapter is configured to have a securing mechanism that allows the medical personnel to secure the medication catheter in place. A one way valve fitted to the apertured arm that forms the input port of the adapter prevents any back flow of fluid from the input port. The catheter is manufactured with calibration markings, most likely equally spaced, and a radiopaque line along its length to enhance the maneuvering and the positioning thereof in the patient so that the distal tip of the catheter could be accurately positioned to the desired location of the patient'"'"'s tracheal/bronchial tree. As a result, the localized treatment such as the injection of a medicament is accurately provided to the appropriate location where the need is the greatest.

Claims

1. An adapter for use with an endotracheal or tracheal tube to enable localized treatment to selected areas of the lungs of a patient through said tube, comprising:

a hollow body having a distal end fittable to a proximal end of said tube, a distal end of said tube extending into the trachea of said patient, said body having a proximal end in linear relationship to its distal end connectable to at least one external system for enhancing the breathing of said patient;

an apertured arm having a distal end integrated at an angle to a side of said body, the proximal end of said arm having mounted thereabout a securing means for selectively preventing the movement of a catheter inserted through the aperture of said arm;

a one way valve means positioned within said arm to prevent back flow of fluids from said tube through said arm;

wherein said valve means is openable by said catheter being inserted to said arm and said catheter is guided along the aperture of said arm to said tube so that the distal end of said catheter is movable through said tube and extendable beyond the distal end of said tube to respective selected areas of the lungs of said patient; and

wherein said catheter provides a guided passage directly to a selected area of the lungs of the patient to enable localized treatment thereat.

2. Adapter of claim 1, wherein said one way valve means comprises a fitting having flexible portions that are pliable so as to open just enough towards the distal end of said arm to allow said catheter to pass through when said catheter is inserted to said arm, said fitting closing when said catheter is withdrawn from said arm.

3. Adapter of claim 1, wherein said valve means comprises a duck bill valve.

4. Adapter of claim 1, wherein said securing means comprises:

threads formed at the outer surface at the proximal end of said arm;

an internally threaded collar matable with the threads at the proximal end of said arm; and

fingers fitted to the inside of said collar compressible in response to the tightening of said collar on said arm, said fingers grasping said catheter and maintaining it in place when said collar is fully threaded to said arm.

5. Adapter of claim 1, wherein said catheter has integrated along substantially the length thereof a radiopaque line for enhancing the placement of said catheter inside the patient.

6. Adaptor of claim 1, wherein said catheter has markings along its length for enabling a user to know the location of the distal end of said catheter relative to said tube, the length of said catheter inserted to said tube being selectively controlled by actuation of said securing means.

7. Adapter of claim 1, further comprising:

an elbow extending from the aperture of said arm internal of said body, said elbow configured to guide the movement of said catheter to ensure that said catheter is moved substantially along the center of said hollow body for insertion to said tube.

8. Adapter of claim 1, wherein said catheter has connected thereto a medicament supply, a suction source or an oxygen supply so that localized medicament, suction or oxygenation treatments, respectively, may be provided to the patient.

9. Adapter of claim 1, wherein said adapter is integrated to a connector to which a suction line and a ventilation line are communicatively coupled.
