Method to manufacture a tube sump with integral clips
First Claim
1. A process for forming a tubular construction that includes a plurality of spaced integral clips for attaching such tubular construction to a separate longitudinal medical procedure tubular device for use as a tube sump attachable to such medical procedure tubular device, comprising:
- providing a longitudinally extending tube having;
a distal end and a proximal end;
at least two lumens extending generally longitudinally through said tube in a generally side-by-side relationship, one of said lumens, defined as a first lumen, configured to be employable as a tube sump and another of said lumens, defined as a second lumen, being available for other uses;
an intermediate wall separating said first and second lumens;
an outer wall surrounding said lumens and said intermediate wall;
said tube, when disposed towards a user with said first and second lumens disposed generally laterally side-by-side, presenting a front tube face and a front tube face view of said tube to the user and, when disposed towards a user with one of said lumens disposed generally forwardly of the other of said lumens, presenting a tube side and tube side view of said tube to the user, said tube face so presented in said tube face view defined to be said front face of said tube, said tube also having a back tube face generally opposite said front face;
forming along and exterior to said first lumen at least a pair of spaced integral clips that project laterally sidewardly from said intermediate wall by;
positioning and aligning said tube for cutting;
cutting a longitudinal slot in said tube, said slot extending through the outer wall adjacent said second lumen into said selected lumen second lumen, the formation of said longitudinal slot effecting a slot opening in said outer wall adjacent said second lumen that separates the wall segments on opposite sides of said slot from one another and forms separated first and second jaw portions on the opposite sides of said slot;
cutting into said tube a lateral cut pattern the individual lateral cuts of which extend generally laterally into said tube from a tube side through said outer wall of said tube adjacent said second lumen into said second lumen towards said intermediate wall between said two lumens, said lateral cuts extending generally cross-ways relative to the longitudinal slot and terminating before penetrating said first lumen, generally along said intermediate wall, said lateral cut pattern including at least a first lateral cut defining a gap in said outer wall adjacent said first lumen between a first outer wall segment above, said gap and a second outer wall segment below said gap, said gap having a length along said tube greater than the longitudinal dimensions of said first and second wall segments, said first outer wall segment with said longitudinal slot therealong having a portion forming a first integral clip nearer said proximal end of said tube and said second outer wall segment with said longitudinal slot therealong having a portion forming a second integral clip nearer said distal end of said tube and spaced from said first integral clip; and
whereby said resulting construction is a longitudinal tubular construction with said first lumen extending therethrough and with spaced integral clips formed therealong extending laterally sidewardly therefrom, said integral clips each including said first and second jaw portions formed from the separated wall segments on the opposite sides of said longitudinal slot, said jaw portions flexibly operable to permit a medical procedure tube to be extending laterally through said slot opening, and also to engage the portion of the medical procedure tube inserted through said slot opening in said integral clips to thereby position and hold said tubular construction along and adjacent to the medical procedure tube.

Abstract
A method of making a tube sump with integral clips from a single material modifies multiple lumen tubing of any material that allows for two or more lumens. Preferably, the tubing is a plastic polymer with dual lumens. One lumen functions as a suction tube and the other lumen undergoes modification to form tubular clips. The modification removes a pattern of tubing opposite the suction tube to form integral clips that retain the tube sump upon an existing endotracheal tube. The removed sections of lumen may have any length or number. Common methods to remove the lumen sections include mechanical cutting, sawing, laser cutting, thermal cutting, melting, ablating, and shearing. Alternatively, the clips may be formed during the manufacture of the multiple lumen tubular product.
