Systems and methods are provided for moving fluids from a patient to a canister and lowering or eliminating the bio-burden of the canister. In one instance, a method for removing fluids from a patient includes using reduced pressure to remove fluids from a patient, delivering the fluids into a reduced-pressure conduit and into a fluid reservoir, exposing the fluids removed from the patient to a UV light source to kill pathogens to create disposable fluids, and disposing of the disposable fluids. Other systems, devices, and methods are presented.

1. A system for removing fluids from a patient using reduced pressure, the system comprising: a reduced-pressure source for providing reduced pressure;a liquid receptor for removing fluids from the patient under the influence of reduced pressure;a canister having a fluid reservoir fluidly coupled to the reduced-pressure source and to the liquid receptor, the canister at least partially being positioned within a canister housing;a reduced-pressure conduit fluidly coupled between the canister and the liquid receptor, the reduced-pressure conduit having at least a UV-transparent portion; anda UV light source positioned in the canister housing to expose fluids traveling through the UV-transparent portion of the reduced-pressure conduit with UV light. 2. The system of claim 1, wherein: the liquid-receptor comprises a wound dressing, which comprises: a manifold for providing reduced pressure to a tissue site on the patient, anda sealing member covering the manifold and forming a fluid seal;the canister comprises a plurality of walls forming the fluid reservoir,at least one wall of the plurality of walls comprises a UV-transparent portion, andthe UV light source is positioned to transmit UV light through the UV-transparent portion of the at least one wall of the plurality of walls. 3. The system of claim 1, wherein the UV light source comprises a tube driver and at least one UV tube. 4. The system of claim 1, wherein: the canister comprises a plurality of walls forming the fluid reservoir,at least one wall of the plurality of walls has a UV-transparent portion, andthe UV light source is positioned to transmit UV light through the UV-transparent portion of the at least one wall of the plurality of walls. 5. The system of claim 1, wherein: the canister comprises a plurality of walls;wherein the plurality of walls comprise a plurality of UV-transparent portions; andthe UV light source comprises a plurality of UV lights positioned proximate the plurality of UV-transparent portions. 6. The system of claim 1, wherein the UV light source is configured to kill at least 95% of the pathogens in the fluids traveling through the UV-transparent portion of the reduced-pressure conduit. 7. The system of claim 1, wherein the UV light source is coupled to the canister. 8. A method for treating fluids from a patient, the method comprising: using a reduced-pressure dressing to remove fluids from the patient;delivering the fluids into a reduced-pressure conduit and into a fluid reservoir, the fluid reservoir at least partially being positioned within a canister housing;positioning a UV light source within the canister housing;exposing the fluids to the UV light source to kill pathogens; anddisposing of the fluids. 9. The method of claim 8, wherein the step of disposing of the fluids comprises disposing of the fluids as domestic waste. 10. The method of claim 8, wherein the reduced-pressure conduit comprises at least a UV-transparent portion and the step of exposing the fluids removed from the patient comprises exposing the fluids in the reduced-pressure conduit proximate the UV-transparent portion to UV light. 11. The method of claim 8, wherein the step of using reduced pressure to remove fluids from the patient comprises using reduced pressure to remove fluids from an open abdomen. 12. The method of claim 8, wherein the reduced-pressure conduit comprises at least a UV-transparent portion and the step of exposing the fluids removed from the patient comprises exposing the fluids in the reduced-pressure conduit proximate to the UV-transparent portion to UV light and exposing the fluids in the fluid reservoir to UV light. 13. The method of claim 8, wherein the fluid reservoir comprises a plurality of walls; andfurther comprising: sterilizing the fluid reservoir in preparation for use by exposing the plurality of walls to radiation whereby the plurality of walls take on a relatively darker tone, andactivating the UV light source whereby the darker tone of the plurality of walls becomes a relatively lighter tone. 14. The method of claim 8, wherein the step of using reduced pressure to remove fluids from a patient comprises using a reduced-pressure pump and controller to generate a reduced pressure applied to the patient and wherein the UV light source comprises a tube driver and at least one UV tube. 15. The method of claim 8, wherein the step of exposing the fluids removed from the patient to a UV light source comprises exposing the fluids to a pulsed UV light source. 16. The method of claim 8, wherein the step of exposing the fluids removed from the patient to a UV light source to kill pathogens comprises exposing the fluids to UV light to kill at least 95% of pathogens in the fluids. 17. The method of claim 8, wherein the step of exposing the fluids removed from the patient to a UV light source to kill pathogens comprises exposing the fluids to UV light to kill at least 98% of pathogens in the fluids. 18. The method of claim 8, wherein exposing the fluids removed from the patient to a UV light source comprises wrapping a spiraled UV light tube around a UV-transparent portion of the reduced-pressure conduit and allowing the fluids to travel through the reduced-pressure conduit. 19. The method of claim 8, wherein the UV light source comprises a UV light tube that has the reduced-pressure conduit wrapped around the UV light tube with UV-transparent portions of the reduced-pressure conduit proximate the UV light tube and wherein the step of exposing the fluids removed from the patient to a UV light source comprises moving the fluids through the reduced-pressure conduit. 20. A method of manufacturing a system for removing fluids from a patient using reduced pressure, the method comprising: providing a reduced-pressure source;forming a canister having a fluid reservoir;positioning the canister at least partially within a canister housing;providing a liquid receptor for removing fluids from the patient under the influence of reduced pressure;providing a reduced pressure conduit for fluidly coupling the canister and the liquid receptor; andpositioning a UV light source within the canister housing to expose fluids from the patient to UV light.
