Patent

CA 2576084

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.

La présente invention concerne un dispositif jetable (1) pour l~introduction, le traitement et l~échantillonnage de matière biologique à partir d~au moins l~une des phases de séparation dans des conditions stériles et de pression constante comprenant un tube à essai stérilisé fermé (2), ledit tube stérile (2) prévoit une première ouverture (4) ou une ouverture d~échantillonnage, la seconde ouverture (7) ou une ouverture d'admission et une troisième ouverture (8), ladite première ouverture (4) prévoit le passage d~une aiguille (5), couplage entre ladite aiguille (5) et la première ouverture (4) étant une fermeture de couplage grâce à un élément élastique (6) permettant la translation sur une direction sensiblement verticale et permettant en outre une inclinaison pour l~aiguille (5), la seconde ouverture (7) étant scellée par une membrane (7) comprenant un matériau permettant à l~aiguille de la seringue de percer et de se refermer après le retrait de l~aiguille, la troisième ouverture (8) prévoit une valve de fermeture (8) stabilisant la pression à l~intérieur du tube d~essai et de la pression environnementale, ledit dispositif (1) comportant des dimensions et des matériaux permettant d~être centrifuge.
