Title (EN) VALVE PORT ASSEMBLY WITH INTERLOCK
(FR) SYSTEME D'ORIFICES DE SOUPAPE A INTERVERROUILLAGE
Abstract:
(EN) A dual port vascular access assembly (20) comprises a first access port (24) and a second access port (28). The linkage is coupled between the first access port (24) to close the second access port (26) in the absence of an access tube in the first access port (24). Such port assemblies are particularly useful for implantation in the patients receiving hemodialysis. By connecting the first access port (24) to the blood withdrawal side of the system (10), blood withdrawal will be automatically terminated upon cessation of blood returned to due loss of the return access tube in the port assembly.
(FR) L'invention concerne un système d'accès vasculaire (20) à deux orifices. Cet ensemble comporte un premier orifice d'accès (24) et un second orifice d'accès (26). Un mécanisme de liaison est accouplé au premier orifice d'accès (24) pour fermer le second orifice d'accès (26) en l'absence d'un tube d'accès dans le premier orifice d'accès (24). De tels systèmes d'accès sont particulièrement indiqués pour être implantés à des patients soumis à une hémodialyse. La connexion du premier orifice d'accès (24) au côté prélèvement sanguin du système (10), permet au prélèvement du sang de s'arrêter automatiquement lorsque le retour de sang est interrompu par le détachement du tube de retour dans le système d'orifices d'accès.
