Multiple function intubation apparatus and method
First Claim
1. An intubation apparatus for providing lavage, sump and enteral feeding functions and the like for a patient, comprising:
- a first tube including at least one passageway and having a first end for introduction into the patient;
port means in the passageway adjacent the first end of the first tube; and
a second tube having a proximal and a distal end, said second tube being received within the passageway of said first tube and movable between an intubation position wherein said second tube is contained within said first tube and an extended position wherein the second tube extends from the first tube so as to open the port means within the passageway for sump operation;
said first tube including a constriction means between said port means and said first end and said second tube including means adjacent the proximal end for engaging said constriction means so as to retain the proximal end of said second tube within the passageway of said first tube when said second tube is in the extended position.

Abstract
An apparatus and its method of use are provided allowing lavage, sump and enteral feeding operations with only one intubation. The apparatus includes a first tube having two distinct passageways. One of these passageways completely contains a second, feeding tube during intubation. Once the first tube is in place in the patient, the second tube is extended from the first tube so as to enter the stomach. The extension of the second tube opens ports in the first passageway of the first tube, thereby allowing sump or lavage treatment with the second passageway of the first tube serving as an air vent. A constriction in the end of the first passageway engages a band on the proximal end of the second tube to keep the tubes together. Once gastric emptying of the patient resumes, the second tube immediately moves into the duodenum then into the jejunum past the Ligament of Treitz and the first tube is withdrawn from the patient while maintaining the second tube in position for enteral feeding through feeding ports in its distal end.

9. A method of providing lavage, sump and feeding functions to a patient with a single intubation, comprising the steps of:
-
introducing a multiple function intubation apparatus through the nose of the patient and guiding the apparatus into the stomach; extending a feeding tube from the apparatus to open ports in an outer tube of the apparatus allowing lavage and sump function, said feeding tube remaining coiled in the stomach until gastric emptying advances the feeding tube into the duodenum; withdrawing the outer tube and proximal end of the feeding tube from the nose of the patient while maintaining the distal end of the feeding tube in the duodenum allowing enteral feeding function. - View Dependent Claims (10)
