Title
(EN) HEMODIALYSIS ACCESS SYSTEM
(FR) SYSTÈME D'ACCÈS À L'HÉMODIALYSE
Abstract
(EN)
A medical blood access system used for hemodialysis treatment to enable blood withdrawal for processing of blood by an external apparatus and return the same blood to a patient, comprising an interfacial fluid conduit between the machine and patient's blood supply which is repeatedly connectable along a guided pathway passing through epidermis and subcutaneous tissue via a naturally formed tissue tract to enter blood space, providing improved patient safely, convenience, effective prophylaxis, without bleeding or tissue trauma or pain, and is executable by the patient to precisely connect and disconnect with minimal disfigurement or life restrictions, and is useable on virtually all patients soon after placement and is robust and safe to high blood flow.
(FR)
La présente invention concerne un système médical d'accès au circuit sanguin utilisé dans un traitement par hémodialyse permettant de prélever le sang afin de le traiter par le biais d'un appareil externe et de le retourner dans la circulation sanguine du même patient. Ledit système comprend un conduit de fluide interfacial situé entre la machine et le dispositif d'alimentation en sang du patient qui peut être connecté de manière répétée le long d'une voie de guidage passant à travers l'épiderme et les tissus sous-cutanés via le tractus des tissus se formant naturellement pour entrer dans l'espace sanguin, améliorant la sécurité du patient, le côté pratique du système, l'efficacité de la prophylaxie, évitant les saignements ou les traumatismes tissulaires ou la douleur. Ledit système peut également être connecté et déconnecté de manière précise par le patient avec un préjudice et des restrictions moindres sur la vie de tous les jours, et peut être utilisé virtuellement sur l'ensemble des patients immédiatement après son installation et celui-ci est robuste et sûr même avec un débit sanguin élevé.
