I claim the ornamental design of sheath and probe for disinfecting conduit, as shown and described.
FIG. 1 is a rear-perspective view of the device, including a sheath and a probe within the sheath. The probe is magnetically suspended within the sheath in FIG. 1.
FIG. 2 is a front-perspective view thereof;
FIG. 3 is a side view thereof;
FIG. 4 is a top-perspective view thereof;
FIG. 5 is another top-perspective view thereof, with the probe partially removed from the sheath. The probe may include an ultraviolet (UV) light source; and,
FIG. 6 is another top-perspective view of the device of FIG. 1, with the probe magnetically suspended within the sheath. The broken lines in FIG. 6 illustrate an example conduit, which may be passed within the sheath and over the probe, in order to expose the conduit to UV light emitted from the probe, thereby disinfecting the conduit. The broken lines form no part of the claimed design.
