A device 1 suitable for use in the ultra-violet irradiation of a fluid such as blood or a fraction thereof comprises a vessel 2 having an inlet 3 and an outlet 5 and a passage means 8 extending therebetween. The said passage means 8 has wall means substantially transparent to ultra-violet irradiation, and at least one irradiation zone 10 extending along and in substantially direct proximity to the wall means, and at least one mixing zone 11, formed and arranged for thoroughly mixing fluid passing therethrough so as to bring substantially the whole of it into a said irradiation zone 10 during passage between the inlet 3 and outlet 5. In use of the device 1 substantially the whole of a body of fluid passed through the vessel 2 may be exposed to a similar substantial level of u.v. irradiation. The device is used in a method of inactivation of micro-organisms and/or lymphocytes in a fluid by irradiating it with u.v. radiation. <IMAGE> |
