DISPOSABLE DEVICE FOR ONE OR MORE INTRODUCTIONS, TREATMENT AND SAMPLING OF BIOLOGICAL MATERIAL FROM AT LEAST ONE OF THE SEPARATION PHASES PRESENT WITHIN THE DEVICE, UNDER STERILITY CONDITIONS AND CONSTANT PRESSURE

摘要

The invention relates to a disposable device (1) for introduction, treatmentand sampling of biological material from at last one of the separation phasesunder sterility and constant pressure conditions comprising a sealed steriletest tube (2), said sterile tube (2) providing a first opening (4), orsampling opening, a second opening (7) or inlet opening, and a third opening(8), said first opening (4) providing the passage of a needle (5), couplingbetween said needle (5) and the first opening (4) being a sealing coupling byan elastic element (6) allowing translation in a substantially verticaldirection and further allowing inclination of the needle (5), said secondopening (7) being sealed by a membrane (7) comprised of a material allowingthe piercing by a syringe needle and closing back after the removal of theneedle, said third opening (8) providing a sealing valve (8) balancing thepressure inside the test tube and environmental pressure, said device (1)having dimensions and materials allowing its centrifugal.
