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, treatment and sampling of biological material from at last one of the separation phases under sterility and constant pressure conditions comprising a sealed sterile test tube (2), said sterile tube (2) providing a first opening (4), or sampling opening, a second opening (7) or inlet opening, and a third opening (8), said first opening (4) providing the passage of a needle (5), coupling between said needle (5) and the first opening (4) being a sealing coupling by an elastic element (6) allowing translation in a substantially vertical direction and further allowing inclination of the needle (5), said second opening (7) being sealed by a membrane (7) comprised of a material allowing the piercing by a syringe needle and closing back after the removal of the needle, said third opening (8) providing a sealing valve (8) balancing the pressure inside the test tube and environmental pressure, said device (1) having dimensions and materials allowing its centrifugal.
