  • the fibrinogen is capable of a polymerizing and being cross-linked to form a solid fibrin clot when the components are mixed.
  • the necessary additional factors to simulate relevant portions of the natural blood coagulation cascade are suitably distributed between the fibrinogen and thrombin components .
  • a popular manually operable applicator for such two-component sealants employs a dual syringe construction wherein two syringes, connected by a yoke, each provide a reservoir for one of the components.
  • the sealant components are discharged in separate streams and mixed externally of the applicator.
  • Such applicators are similar in principle to household epoxy glue applicators commonly available in hardware stores.
  • fibrin sealant was not commercially available in the US, therefore use of fibrin sealant was limited to supplies produced within the clinic, which are not subject to FDA control.

This positioning allows vial 130 to be firmly held in place by support 126, while still allowing vile 130 to pivot in the direction of arrow 184. By allowing vial 130 to fully seat within vial support surface 134, vial 130 will maintain a level position during the first part of the insertion of the drawing tube.

Abstract

L'invention concerne un dispositif de remplissage (10) et un procédé destinés en particulier à des scellants à deux composants, tels que les scellants de la fibrine, permettant d'injecter deux fluides provenant de deux flacons (28, 29) de stockage, séparément et directement, dans les réservoirs d'un applicateur (18) de fluide à double seringue, lesdits flacons pouvant être des flacons normalisés, étanches et stériles. Le dispositif comprend un raccord (16) en prise avec l'applicateur (18) de fluide, conçu de façon à orienter les réservoirs de fluide de l'applicateur d'une manière prédéterminée et de façon à maintenir les flacons (28, 29) côte-à-côte en alignement avec l'applicateur (18). Deux conduits (26, 27) de fluide, dont les extrémités inférieures peuvent former des pointes (30, 31) permettant de percer les sceaux des flacons (28, 29), s'étendent entre l'applicateur (18) et les flacons (28, 29), pouvant chacun comprendre un élément d'assemblage transversal qui s'adapte aux dimensions des flacons (28, 29). Le dispositif permet d'incliner les flacons (28, 29) de façon que les conduits (26, 27) puissent retirer un maximum de fluide du fond du flacon (28, 29). L'inclinaison peut être effectuée par un mouvement vers le bas du dispositif qui supporte l'applicateur, ce mouvement permettant d'introduire les conduits de fluide dans les flacons. Une enveloppe peut renfermer et étanchéiser les flacons et permettre à l'ensemble appareil et applicateur de fluide d'être introduit dans un environnement stérile. L'invention concerne également d'autres modes de réalisation dans lesquels un seul flacon est utilisé.
