1. A UV light disinfection device comprising a flexible elongated tubular body with closed ends, the flexible elongated tubular body comprising:
a tube wall having a refractive index n2, wherein the tube wall is transparent to ultraviolet (UV) light;
a proximal end closed by a first closure;
a connector piece arranged on the proximal end and abutting the first closure;
a housing comprising a UV light source for providing UV light, wherein the housing is releasably connected to the connector piece;
a distal end closed by a second closure joined with the flexible elongated tubular body; wherein the tube wall, the first closure, and the second closure define a closed inner lumen along the full length of the flexible elongated tubular body; and
a liquid contained within the closed inner lumen between the first closure and the second closure such that the liquid is retained within the closed inner lumen, the liquid having a refractive index n1,
wherein n2/n1<1 so that the UV light disinfection device is configured for guiding UV light from the light source inside the liquid filled inner lumen along a longitudinal direction of the flexible elongated tubular body, wherein a part of the UV light is emitted through the tube wall, such that the UV light disinfection device is configured for emitting UV light radially from and along the length of the flexible elongated tubular body.
