Title
(DE) INJEKTOR ZUR APPLIZIERUNG VON FLÜSSIGKEITEN, INSBESONDERE VON KONTRASTMITTELN FÜR DIE RÖNTGEN- UND KERNSPINTOMOGRAPHIE
(EN) INJECTOR FOR APPLYING FLUIDS, ESPECIALLY CONTRAST AGENTS IN X-RAY AND NUCLEAR SPIN TOMOGRAPHY
(FR) INJECTEUR POUR L'APPLICATION DE LIQUIDES, EN PARTICULIER D'AGENTS DE CONTRASTE EN TOMOGRAPHIE AUX RAYONS X OU A SPIN NUCLEAIRE
Abstract
(DE)
Der erfindungsgemässe Injektor dient zur Applizierung von Kontrastmitteln für die Röntgen- und Kernspintomographie und weist ein aus Verbindungsschläuchen (6) und einem Pumpenschlauch (7) bestehendes Schlauchsystem (5) sowie eine Mehrzahl von Vorratsgefässen (4) auf, die über je einen der Verbindungsschläuche (6) sowie ein Verzweigungsstück (8) an dem zu einer Kanüle führenden Pumpenschlauch (7) angeschlossen sind. Jedem Verbindungsschlauch (6) ist ein Gasblasendetektor (15) sowie ein Ventil (11) zugeordnet, wobei weiterhin dem Pumpenschlauch (7) ein den Flüssigkeitsstrom vom Vorratsgefäss (4) zur Kanüle umkehrendes Pumporgan (16) zugeordnet ist.
(EN)
The injector according to the invention is used for applying contrast agents in X-ray and nuclear spin tomography and comprises a flexible tube system (5) consisting of connecting tubes (6) and pump tubes (7) and a plurality of reservoirs (4) that are connected by one of the connecting tubes (6) and by a branching piece (8) to a pump tube (7) leading to a cannula. A gas bubble detector (15) and a valve (11) are assigned to each connecting tube (6), wherein a pumping organ (16) reversing the flow of the fluid from the reservoir (4) to the cannula is also assigned to the pump tube (7).
(FR)
L'injecteur selon l'invention sert à l'application d'agents de contraste en tomographie aux rayons X ou à spin nucléaire et comprend un système de tuyauterie souple (5) présentant des tuyaux de jonction (6) et un tuyau de pompage (7), et une pluralité de réservoirs (4) raccordés chacun, via l'un des tuyaux de jonction (6) et une pièce de branchement (8), au tuyau de pompage (7) conduisant à une canule. A chaque tuyau de jonction (6) sont associés un détecteur de bulles de gaz et une vanne (11), cependant qu'au tuyau de pompage (7) est associé un organe de pompage (16) inversant le courant liquide du réservoir (4) vers la canule.
