Multiple lumen hose
View Patent ↗A multiple lumen hose includes a generally circumferential base wall. A plurality of corrugations extend radially outward from the base wall. A septum is disposed interior to the base wall such as to divide the interior of the base wall into at least a first lumen and a second lumen. A first scallop extends outward from the circumferential base wall between adjacent corrugations. A second scallop extends outward from the circumferential base wall between adjacent corrugations.
1. A multiple lumen hose, the hose comprising:
a generally circumferential base wall defining an interior;
a plurality of corrugations extending radially outward from the base wall;
a septum disposed interior to the base wall such as to divide the base wall into at least a first lumen and a second lumen, the septum secured to the circumferential base wall;
a first scallop extending outward from the circumferential base wall between adjacent corrugations in a localized area about the septum, the septum secured to and extending into the first scallop; and
a second scallop extending outward from the circumferential base wall between adjacent corrugations in a localized area about the septum, the septum secured to and extending into the second scallop.
2. The multiple lumen hose of claim 1 , wherein the first and second scallops extend radially outward from respective center points aligned on the lumen and different from a center point of the circumferential base wall.
3. The multiple lumen hose of claim 1 , wherein the plurality of corrugations extend radially past the first scallop and the second scallop.
4. The multiple lumen hose of claim 3 , wherein the first scallop and the second scallop extend in a radial direction about half way between the circumferential base wall and the plurality of corrugations.
5. The multiple lumen hose of claim 1 , wherein the first and second scallops reduce a distance that the septum and the corrugations are stretched.
6. The multiple lumen hose of claim 1 , wherein a conduit is formed by vacuum molding an extrusion comprising the circumferential base wall and the septum.
7. The multiple lumen hose of claim 6 , wherein the vacuum molding forms the first and second scallops and the corrugations by stretching the base wall and the septum.
8. The multiple lumen hose of claim 1 , wherein the septum is dimensioned to extend between the opposed first and second scallops.
9. The multiple lumen hose of claim 1 , wherein the scallops reduce the stretching of the corrugations at an intersection or with the septum.
10. The multiple lumen hose of claim 9 , wherein the stretched septum is of a generally constant thickness.
