Medical tube
Disclosed is a tube comprising at least one lumen, and a wall comprising at least one or a plurality of wave-guide(s). The wall encloses the at least one lumen. The tube comprises a distal end configured for being introduced into a body of a mammal and a proximal end comprising a tube-connector. The wave-guide(s) are configured to conduct electro-magnetic radiation along the tube. The tube is configured to emit at least a part of the radiation into the lumen and/or to an outer surface of the tube. The wave-guide(s) are configured for transmitting and side-emitting UV-light comprising a wave-length of 200-280 nm, preferably 210-260 nm, and still more preferably 210-230 nm. The wall comprises fluorinated ethylene-propylene. Further disclosed is a system comprising the tube and a radiation source configured for emitting electro-magnetic radiation, preferably UV-C light. Also, a method for using the tube is disclosed. The method comprises applying the tube to a body of a patient.
