Abstract
Abstract A multi-lumen drainage tube or catheter body includes a primary drainage lumen and separate auxiliary lumens with obstructed proximal ends wherein the tube may be used a simple, single lumen drainage tube, a two lumen drainage tube or a three lumen drainage tube by removal of one or both of the obstructions from the proximal ends of the auxiliary lumens and connection of the lumen openings at the proximal end of the drainage tube to the corresponding single or multi-lumen adaptor. In the second aspect of the invention, a drainage tube system is provided which may employ the adaptable multi-lumen drainage tube of the first aspect of the invention and wherein the adaptors employed therewith are provided with a mechanism for selectively inserting a flexible, elongated clean-out catheter into and down the length within the main drainage lumen to pass the distal end of the catheter through accumulated matter and to introduce a high suction pressure through the clean-out catheter lumen to evacuate the loosened obstructing matter from the main drainage lumen. The adaptor through which the clean-out catheter is introduced preferably includes a main lumen connector adapted to be connected to the drainage lumen and having two branches extending therefrom. The main branch preferably includes a valve for closing the first branch and a further connector for connection of the main drain lumen to the fluid collection vessel and low pressure pump when the valve is opened. The second branch preferably includes a connector having a fluid seal therein that bears against the exterior surface of the clean-out catheter and through which the clean-out catheter may be advanced and retracted. The clean-out catheter is preferably encased within a flexible, compressible sheath wherein both the sheath and the proximal end of the clean-out catheter are joined at a normally-closed valve and connector body adapted to be connected to a high suction pressure source and collection vessel.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
119 words
An adaptable surgical drain for use with external drainage facilitating equipment in evacuating body fluids accumulating inside the body percutaneously into fluid vessels comprising: a multi-lumen catheter body having proximal and distal ends, including a drainage lumen extending between openings in the proximal and distal ends thereof and at least one auxiliary lumen extending between openings in the proximal and distal ends thereof; and a molded in place obstruction obstructing the proximal end opening of at least one auxiliary lumen, whereby, in use, the obstruction may be left intact in order to use the multi-lumen catheter body as a single lumen surgical drain or the obstruction may be severed and the catheter body used as a multi-lumen surgical drain.
Claim 2
Dependent Claim
119 words
An adaptable surgical drain for use with external drainage facilitating equipment in evacuating body fluids accumulating inside the body percutaneously into fluid vessels comprising: a multi-lumen catheter body having proximal and distal ends, including a drainage lumen extending between openings in the proximal and distal ends thereof and at least one auxiliary lumen extending between openings in the proximal and distal ends thereof; and a molded in place obstruction obstructing the proximal end opening of at least one auxiliary lumen, whereby, in use, the obstruction may be left intact in order to use the multi-lumen catheter body as a single lumen surgical drain or the obstruction may be severed and the catheter body used as a multi-lumen surgical drain.
Claim 3
Dependent Claim
58 words
The surgical drain of claim 1 wherein the catheter body further comprises: first and second auxiliary lumens extending between respective openings in the proximal and distal ends thereof; and molded in place obstructions obstructing the proximal end openings of the first and second auxiliary lumens that are selectively removable to use the surgical drain with irrigation and ventilation.
Claim 4
Dependent Claim
45 words
The surgical drain of claim 2 wherein the catheter body is constructed of a soft, pliant material capable of being severed in the proximal end region to cut away the obstructions in the proximal end openings of one or both of the auxiliary lumens thereof.
Claim 5
Dependent Claim
27 words
The surgical drain of claim 3 wherein the multi-lumen catheter body is constructed of a material selected from the group comprising polyvinyl chloride and silicone rubber compounds.
Claim 6
Dependent Claim
41 words
The surgical drain of claim 1 wherein the catheter body is constructed of a soft, pliant material capable of being severed in the proximal end region to cut away the obstruction in the proximal end opening of the auxiliary lumen thereof.
Claim 7
Dependent Claim
27 words
The surgical drain of claim 5 wherein the multi-lumen catheter body is constructed of a material selected from the group comprising polyvinyl chloride and silicone rubber compounds.
Claim 8
Dependent Claim
171 words
A surgical wound drainage assembly for use with external drainage facilitating equipment in evacuating body fluids accumulating inside the body percutaneously into fluid vessels comprising: a multi-lumen catheter body having a drainage lumen extending between proximal and distal end openings in the proximal and distal end of the catheter body and at least one auxiliary lumen extending in parallel with the main lumen between proximal and distal openings in the proximal and distal ends of the catheter body; a molded in place obstruction obstructing the proximal opening of at least one auxiliary lumen; first adaptor means for selective attachment with only the proximal opening of the drainage lumen for coupling the drainage lumen with the external drainage facilitating equipment and leaving the proximal opening of the auxiliary lumen obstructed; and second adaptor means for alternative selective attachment with both the proximal opening of the drainage lumen and the unobstructed opening of the auxiliary lumen, wherein the obstruction in the auxiliary lumen is severed to effect connection with the second adaptor means.
Claim 9
Dependent Claim
171 words
A surgical wound drainage assembly for use with external drainage facilitating equipment in evacuating body fluids accumulating inside the body percutaneously into fluid vessels comprising: a multi-lumen catheter body having a drainage lumen extending between proximal and distal end openings in the proximal and distal end of the catheter body and at least one auxiliary lumen extending in parallel with the main lumen between proximal and distal openings in the proximal and distal ends of the catheter body; a molded in place obstruction obstructing the proximal opening of at least one auxiliary lumen; first adaptor means for selective attachment with only the proximal opening of the drainage lumen for coupling the drainage lumen with the external drainage facilitating equipment and leaving the proximal opening of the auxiliary lumen obstructed; and second adaptor means for alternative selective attachment with both the proximal opening of the drainage lumen and the unobstructed opening of the auxiliary lumen, wherein the obstruction in the auxiliary lumen is severed to effect connection with the second adaptor means.
Claim 10
Dependent Claim
