Description

CONNECTEUR PERMETTANT LE RACCORDEMENT D’UNE LIGNE DE CONNECTOR FOR CONNECTING A LINE OF
TRANSFUSION SUR UNE POCHE SOUPLE TRANSFUSION ON A FLEXIBLE POCKET
Domaine de l’invention Field of the invention
La présente invention se rapporte au domaine des poches à usage médical. The present invention relates to the field of pouches for medical use.
La présente invention concerne plus particulièrement un connecteur permettant le raccordement d’une ligne de transfusion sur une poche souple, qui peut contenir du sang ou des dérivés sanguins. The present invention more particularly relates to a connector for connecting a transfusion line to a flexible bag, which may contain blood or blood derivatives.
Etat de la technique State of the art
Dans le domaine de la perfusion ou de la transfusion, il existe une pièce appelée connecteur ou « twist-off » en terminologie anglo-saxonne, permettant de connecter la ligne de perfusion à la poche souple contenant le produit à perfuser. Les lignes de perfusion sont équipées d’un trocard ou « spike » en terminologie anglo-saxonne, qui est introduit en force dans le connecteur. Lors de cette opération, le trocard perfore une membrane, ce qui permet l’écoulement du liquide contenu dans la poche. In the field of perfusion or transfusion, there is a piece called connector or "twist-off" in English terminology, for connecting the infusion line to the flexible bag containing the product to be infused. The perfusion lines are equipped with a trocar or "spike" in English terminology, which is forced into the connector. During this operation, the trocar punches a membrane, which allows the flow of the liquid contained in the pocket.
Le connecteur doit être conforme aux normes ISO 15747 pour les poches de perfusion et 3826 pour les poches de sang et dérivés sanguins. Le connecteur est composé de plusieurs fonctions concernant la pénétration du trocard. Une première partie est retirée pour libérer l’accès à la membrane, une seconde partie permettant d’assurer l’étanchéité avant la perforation de la membrane et une troisième partie qui est la fonction membrane. The connector must comply with ISO 15747 for infusion bags and 3826 for blood bags and blood derivatives. The connector is composed of several functions concerning the penetration of the trocar. A first part is removed to release access to the membrane, a second part to ensure sealing before the perforation of the membrane and a third part which is the membrane function.
Il existe des connecteurs composés de plusieurs éléments et d’autres réalisés en une seule pièce : les connecteurs de type « twist-off ». There are connectors composed of several elements and others made in one piece: connectors type "twist-off".
Dans de nombreux cas, le connecteur est fabriqué dans la même famille de matériau que le film qui constitue la poche. Dans le cas des poches contenant du sang, le matériau privilégié est l’EVA (éthylène-acétate de vinyle), qui est issu de la copolymérisation de l’éthylène avec l’acétate de vinyle. Il s’agit d’une matière souple mais collante. Dans le cas des poches contenant du sang, le connecteur de type « twist-off » est également en EVA. In many cases, the connector is manufactured in the same family of material as the film that constitutes the pocket. In the case of bags containing blood, the preferred material is EVA (ethylene-vinyl acetate), which is derived from the copolymerization of ethylene with vinyl acetate. It is a soft but sticky material. In the case of bags containing blood, the connector type "twist-off" is also in EVA.
Pour les autres matériaux, il est fréquent de générer un bourrelet d’étanchéité, qui est démoulé en force pendant la phase d’injection du connecteur. For other materials, it is common to generate a sealing bead, which is demolded force during the injection phase of the connector.
On connaît dans l’état de la technique le brevet français N° FR 3 007 496 B1 (Technoflex), qui se rapporte à un procédé de fabrication d’un raccord. Ce brevet français se rapporte plus particulièrement à un procédé de fabrication d’un raccord pour un récipient à usage médical destiné à l’administration de fluide, ledit raccord comprenant un corps principal définissant un canal intérieur pour le passage d’un fluide et au moins un bourrelet continu ou discontinu, formant saillie à l’intérieur dudit canal. It is known in the state of the art the French patent No. FR 3 007 496 B1 (Technoflex), which relates to a method of manufacturing a connector. This French patent relates more particularly to a method of manufacturing a connector for a container for medical use intended for the administration of fluid, said connection comprising a main body defining an internal channel for the passage of a fluid and at least one a continuous or discontinuous bead protruding inside said channel.
Le matériau EVA ne permet pas de générer un bourrelet lors de l’injection, qui soit conforme géométriquement et qui ne génère pas de particules. La fonction étanchéité est donc réalisée par toute la surface du diamètre intérieur du connecteur. La zone de soudure du connecteur de type « twist-off » sur la poche renforce cette zone d’étanchéité. The EVA material does not generate a bead during injection, which is geometrically compliant and does not generate particles. The sealing function is therefore performed by the entire surface of the inner diameter of the connector. The weld zone of the "twist-off" type connector on the pocket strengthens this sealing zone.
De plus, les trocards sont normés en Europe, mais pas aux Etats-Unis. In addition, trocards are standardized in Europe, but not in the United States.
Il existe également des connecteurs réalisés en plusieurs pièces. There are also connectors made in several pieces.
