Abstract: Disclosed is an enzymatic composition including:—at least one enzyme, termed plasminogenase, for converting, into plasmin, plasminogen from a blood plasma medium including plasminogen;—a solid support that is insoluble in aqueous solution, the solid support having dimensions suitable for being able to be retained on a filter having a cut-off threshold of less than or equal to 0.22 ?m. The plasminogenase is bound to the solid support and remains bound to this support on contact with a blood plasma medium. The composition is in the dry state. Also disclosed is a process for preparing such an enzymatic composition, to the use thereof and to a device (20) for preparing a blood plasma medium ex vivo rich in sterile plasmin and free of enzymatic composition.

Abstract: A device and a procedure for the extemporaneous preparation of an individual quantity of sterile treatment fluid that may be compressible, in particular a treatment gas, the device comprising a rigid cartridge (3) with an outlet valve, an administration syringe (4) and a filtration-type connection/sterilization device (5, 6). The cartridge (3) simply contains an individual quantity of treatment fluid under pressure, and the cylinder of the syringe (4) is adapted to contain this individual quantity.
