A first fiberoptic cable is engaged to a wall of the tube so that a first end of the first fiberoptic cable is positioned proximate to a first terminus of the tube. The first fiberoptic cable has a second end operationally engaged an ultraviolet C light emitter so that ultraviolet C light is emitted proximate to the first terminus of the tube. The first fiberoptic cable directs the ultraviolet C light from the ultraviolet C light emitter so that the ultraviolet C light impinges upon tissue and pathogens proximate to the first terminus of the tube to inactivate the pathogens. ## Claims ### Claim 1 A far ultraviolet light application device comprising: a tube configured to be utilized in a medical procedure; a first fiberoptic cable engaged to a wall of the tube, the first fiberoptic cable having a first end positioned proximate to a first terminus of the tube, the first fiberoptic cable having a second end configured for operationally engaging an ultraviolet C light emitter, such that ultraviolet C light is emitted proximate to the first terminus of the tube, wherein the first fiberoptic cable is configured for directing the ultraviolet C light from the ultraviolet C light emitter such that the ultraviolet C light impinges upon tissue and pathogens proximate to the first terminus of the tube, for inactivating the pathogens; and an adapter selectively engageable to the tube and being configured for selectively engaging a medical instrument, such that the tube is removably engaged to the medical instrument, wherein the adapter comprises: a plate shaped complementarily to a portion of the medical instrument; a set of clips engaged to the plate and being configured for engaging the medical instrument, such that the adapter is removably engaged to the medical instrument with the plate overlying the portion of the medical instrument; and a receptacle engaged to the plate, the receptacle being complementary to the tube, such that the receptacle is positioned for insertion of the tube for removably engaging the tube to the adapter. ### Claim 2 (depends on 1) The far ultraviolet light application device of claim 1, wherein the tube is configured for suctioning. ### Claim 3 (depends on 1) The far ultraviolet light application device of claim 1, wherein the ultraviolet C light emitter emits at 222 nanometers, such that the ultraviolet C light is nondamaging to mammalian tissue. ### Claim 4 (depends on 1) The far ultraviolet light application device of claim 1, further including a second fiberoptic cable engaged to the tube and terminating proximate to the first terminus of the tube, the second fiberoptic cable being configured for operationally engaging a visible light emitter, such that visible light is emitted proximate to the first terminus of the tube, wherein the second fiberoptic cable is configured for directing the visible light such that the visible light illuminates the tissue proximate to the first terminus of the tube. ### Claim 5 (depends on 4) The far ultraviolet light application device of claim 4, wherein the visible light emitter comprises a light emitting diode. ### Claim 6 (depends on 1) The far ultraviolet light application device of claim 1, further including a first connector engaged to a second end of the first fiberoptic cable and being configured for selectively engaging a second connector, the second connector being operationally engaged to the ultraviolet C light emitter, such that the first connector is positioned for selectively engaging the second connector for optically engaging the first fiberoptic cable to the ultraviolet C light emitter. ### Claim 7 (depends on 4) The far ultraviolet light application device of claim 4, further including a first connector engaged to a second end of the first fiberoptic cable and being configured for selectively engaging a second connector, the second connector being operationally engaged to the ultraviolet C light emitter and the visible light emitter, such that the first connector is positioned for selectively engaging the second connector for optically engaging the first fiberoptic cable to the ultraviolet C light emitter and the second fiberoptic cable to the visible light emitter. ### Claim 8 A far ultraviolet light application device comprising: a tube configured to be utilized in a medical procedure, the tube being configured for suctioning; a first fiberoptic cable engaged to a wall of the tube, the first fiberoptic cable having a first end positioned proximate to a first terminus of the tube, the first fiberoptic cable having a second end configured for operationally engaging an ultraviolet C light emitter, such that ultraviolet C light is emitted proximate to the first terminus of the tube, wherein the first fiberoptic cable is configured for directing the ultraviolet C light from the ultraviolet C light emitter such that the ultraviolet C light impinges upon tissue and pathogens proximate to the first terminus of the tube, for inactivating the pathogens, the ultraviolet C light emitter emitting at 222 nanometers, such that the ultraviolet C light is nondamaging to mammalian tissue; a second fiberoptic cable engaged to the tube and terminating proximate to the first terminus of the tube, the second fiberoptic cable being configured for operationally engaging a visible light emitter, such that visible light is emitted proximate to the first terminus of the tube, wherein the second fiberoptic cable is configured for directing the visible light such that the visible light illuminates the tissue proximate to the first terminus of the tube, the visible light emitter comprising a light emitting diode; and an adapter selectively engageable to the tube and being configured for selectively engaging a medical instrument, such that the tube is removably engaged to the medical instrument, the medical instrument comprising an examination instrument, a surgical instrument, a dental instrument, or a veterinary instrument, the adapter comprising: a plate shaped complementarily to a portion of the medical instrument, a set of clips engaged to the plate and being configured for engaging the medical instrument, such that the adapter is removably engaged to the medical instrument with the plate overlying the portion of the medical instrument, and a receptacle engaged to the plate, the receptacle being complementary to the tube, such that the receptacle is positioned for insertion of the tube for removably engaging the tube to the adapter.
