A system for delivering multiple fluids to a patient, comprising an infusion pump comprising: a first port and second port opening to at least a first manifold and a second manifold, respectively, within the infusion pump, wherein each of the first port and the second port has a feature element associated therewith, wherein the feature element of the first port is different than the feature element of the second port; a power source located within the pump housing and positioned between the first manifold and the second manifold, the first manifold and the second manifold of the infusion pump being laterally spaced apart from each other within the pump housing; a multi-channel lumen assembly having a first tube having an inlet port configured to be fluidly coupled to the first port of the infusion pump, the first tube further comprising an outlet port, and a second tube having an inlet port configured to be fluidly coupled to the second port of the infusion pump, the second tube further comprising an outlet port, wherein the outlet port of the first tube of the multi-channel lumen assembly has a feature element associated therewith and the outlet port of the second tube of the multi-channel lumen assembly has a feature element associated therewith, and an infusion set having a first inlet port configured to fluidly couple to the outlet port of the first tube, and a second inlet port configured to fluidly couple to the outlet port of the second tube, wherein the infusion set is configured to deliver the fluids to the patient, wherein the first inlet port has a feature element associated therewith and the second inlet port has a feature element associated therewith, wherein the feature element of the outlet port of the first tube is complementary in shape to the feature element of the first inlet port of the infusion set and the feature element of the outlet port of the second tube is complementary in shape to the feature element of the second inlet port of the infusion set, such that when assembled the outlet port of the first tube is capable of only being fluidly coupled to the first inlet port and the outlet port of the second tube is capable of only being fluidly coupled to the second inlet port, thereby preventing mischanneling of the fluids. an infusion pump comprising: a first port and second port opening to at least a first manifold and a second manifold, respectively, within the infusion pump, wherein each of the first port and the second port has a feature element associated therewith, wherein the feature element of the first port is different than the feature element of the second port; a power source located within the pump housing and positioned between the first manifold and the second manifold, the first manifold and the second manifold of the infusion pump being laterally spaced apart from each other within the pump housing; a first port and second port opening to at least a first manifold and a second manifold, respectively, within the infusion pump, wherein each of the first port and the second port has a feature element associated therewith, wherein the feature element of the first port is different than the feature element of the second port; a power source located within the pump housing and positioned between the first manifold and the second manifold, the first manifold and the second manifold of the infusion pump being laterally spaced apart from each other within the pump housing; a multi-channel lumen assembly having a first tube having an inlet port configured to be fluidly coupled to the first port of the infusion pump, the first tube further comprising an outlet port, and a second tube having an inlet port configured to be fluidly coupled to the second port of the infusion pump, the second tube further comprising an outlet port, wherein the outlet port of the first tube of the multi-channel lumen assembly has a feature element associated therewith and the outlet port of the second tube of the multi-channel lumen assembly has a feature element associated therewith, and a first tube having an inlet port configured to be fluidly coupled to the first port of the infusion pump, the first tube further comprising an outlet port, and a second tube having an inlet port configured to be fluidly coupled to the second port of the infusion pump, the second tube further comprising an outlet port, wherein the outlet port of the first tube of the multi-channel lumen assembly has a feature element associated therewith and the outlet port of the second tube of the multi-channel lumen assembly has a feature element associated therewith, and an infusion set having a first inlet port configured to fluidly couple to the outlet port of the first tube, and a second inlet port configured to fluidly couple to the outlet port of the second tube, wherein the infusion set is configured to deliver the fluids to the patient, wherein the first inlet port has a feature element associated therewith and the second inlet port has a feature element associated therewith, wherein the feature element of the outlet port of the first tube is complementary in shape to the feature element of the first inlet port of the infusion set and the feature element of the outlet port of the second tube is complementary in shape to the feature element of the second inlet port of the infusion set, such that when assembled the outlet port of the first tube is capable of only being fluidly coupled to the first inlet port and the outlet port of the second tube is capable of only being fluidly coupled to the second inlet port, thereby preventing mischanneling of the fluids.
