The invention relates to an apparatus for the irradiation of body fluids, espe- cially blood and/or tissue extracts, by ultraviolet light in a containment (4) for receiving the body fluids which is disposed in the radiation range of an ultraviolet light source (5). On the inside of this containment (4) there are pro- vided baffle means (6, 26, 36) arranged so as to subject the body fluids flowing through the containment or circulating therewithin in circumferential direction to turbulence thereby preventing a laminar flow within the body fluid. Thereby the body fluid in the containment is uniformly exposed to the UV radiation in its entire volume.

L'invention concerne un dispositif permettant d'exposer des échantillons de liquides organiques, notamment des échantillons de sang et/ou d'extraits tissulaires, à de la lumière ultraviolette. Ce dispositif comprend un récipient collecteur (4) destiné à contenir les échantillons de liquides organiques et qui peut être placé dans la zone de rayonnement d'une lampe à rayons ultraviolets (5). A l'intérieur du récipient collecteur (4), il est prévu un dispositif à chicanes (6, 26, 36) servant à créer des turbulences dans un liquide organique qui traverse ledit récipient collecteur ou qui circule dans le sens périphérique. La conséquence en est qu'un écoulement laminaire dans le liquide organique est arrêté dans la plus large mesure possible et que l'on parvient à l'exposition la plus uniforme possible aux U.V. dans le volume global de l'échantillon de liquide, grâce aux turbulences produites.
