Abstract

Exemplary embodiments provide a multi-medicament infusion system (10) for preventing the mischanneling of medicaments. The system may include an infusion pump (12), medicament reservoirs (16A,16B), a multi-channel lumen (18), and an infusion set (20). The medicament reservoirs may be sized and shaped differently such that the medicament reservoirs can only be inserted into the infusion pump in a unique configuration. The multi-channel lumen may include connectors that mate to corresponding connectors on the infusion pump and the infusion set only in a unique configuration. Because the various parts of the multi-infusion system may only be connected in the unique configuration, the expected medicaments may be administered appropriately and channeled to the correct infusion sites.

Claims

1. A system for delivering multiple fluids to a patient, comprising

at least first and second reservoirs, wherein each of the first and second reservoirs houses a fluid and has a feature element associated therewith, wherein the feature element of the first reservoir is different than the feature element of the second reservoir,

at least first and second manifolds for completely housing the first and second reservoirs, respectively, wherein each of the manifolds has a feature element associated therewith, wherein the feature element of the first manifold is different than the feature element of the second manifold,

wherein the feature element of the first reservoir is complementary to the feature element of the first manifold and the feature element of the second reservoir is complementary to the feature element of the second manifold, such that when assembled the first reservoir is capable of only being fluidly coupled to the first manifold and the second reservoir is capable of only being fluidly coupled to the second manifold, thereby preventing mischanneling of the fluid,

wherein the first manifold includes a first outlet port and the second manifold includes a second outlet port, and wherein the first and second outlet ports are coupled to first and second inlet ports of an infusion pump;

wherein the first and second manifolds are disposed on an outside of the infusion pump.

2. The system of claim 1, wherein the first reservoir houses a regulating agent and the second reservoir houses a counter-regulatory agent.

3. The system of claim 1, wherein the feature element of the first inlet port comprises a first surface feature and the feature element of the second inlet port comprises a second surface feature, wherein the first surface feature is different than the second surface feature.

4. The system of claim 1, wherein the first and second manifolds each have formed therein a piercing element for piercing the first and second reservoirs, respectively.

5. The system of claim 1, wherein the infusion pump comprises first and second outlet ports fluidly coupled to the first and second inlet ports of the infusion pump.

6. The system of claim 1, further comprising a multi-channel lumen assembly having a first tube having an inlet port fluidly coupled to the first outlet port of the infusion pump and an outlet port, and a second tube having an inlet port fluidly coupled to the second outlet port of the infusion pump and an outlet port, and an infusion set having a first inlet port fluidly coupled to the outlet port of the first tube, and a second inlet port fluidly coupled to the outlet port of the second tube, wherein the infusion set is configured to deliver the fluids to the patient.

7. The system of claim 1, wherein each of the first and second manifolds comprises a housing having an inner wall defining a chamber, and a connector end portion for coupling the manifolds to the infusion pump or to an intermediary coupling piece.

8. The system of claim 1, wherein each of the first. and second manifolds comprises a housing having an inner wall defining a chamber, the chamber having a bottom surface, and a piercing element extending outwardly from the bottom surface.

9. The system of claim 8, wherein each of the manifolds further comprises a base portion coupled to the housing, and a fluid passage coupled to the piercing element.

10. The system of claim 9, wherein the base portions of each of the first and second manifolds can be coupled together.

11. The system of claim 9, wherein the base portions of each of the first and second manifolds are separate and distinct from each other.

12. The system of claim 8, wherein each of the first and second manifolds each include a cap element that is configured to mount to end of the housing opposite the piercing element.
