Blood bag system and process for the deactivation of pathogens in platelet concentrates by using the blood bag system

摘要

Blood bag system comprising a biological fluid such as a platelet concentrate and further comprising: - a storage bag (4) made of plastic material, - an irradiation bag (2) made of a flexible plastic material substantially transparent to UV radiation and having a volume capacity of at least times the volume of the biological fluid contained in the irradiation bag and comprising one or more inlet tubes (1) and / or outlet tubes (3) and , - the storage bag (4) and the irradiation bag (2) being the same bag or at least two different but interconnecting bags, - the irradiation bag (2) comprising a seal (16, 17) that provides a compartment containing the biological fluid to be treated and a separate compartment thereof comprising the internal end or ends of the one or more inlet tubes (1) and / or outlet tubes (3), the seal being located (16, 17 ) in one is Quina of the irradiation bag (2) and providing a cut corner, characterized in that the inside of the irradiation bag (2) comprises cut or rounded corners and because the seal is in the form of a rounded corner.
