Abstract: An assembly used in the injection of a contrast product into a patient is disclosed. This assembly includes a container, an injection flowpath, and a filling flowpath. The injection flowpath extends from the container to the patient, while the filling flowpath extends from a feed source to the container. Part of the injection flowpath is also used by the filling flowpath. One connector is disposed between an upstream filling line tubular section and a pump coupling section within the filling flowpath, while another connector is disposed between a downstream filling line tubular section and this same pump coupling section. This allows the upstream filling line tubular section, the pump coupling section, and the downstream filling line tubular section to differ in one or more respects, for instance with regard to hardness.

Abstract: The present invention relates to an assembly for medical use comprising: an injection line for the transfer of the product to be injected between a container and the patient, said injection line comprising an upstream tubular part and a downstream tubular part and a thresholded non-return valve on the downstream tubular part, said thresholded non-return value allowing the liquid product to pass from the container to the patient, a filling line for the transfer of the product to be injected between a feed source and the container via the upstream tubular part, said filling line being connected to the injection line between the upstream and downstream tubular parts and comprising a non-return valve allowing the liquid product to pass from the feed source to the container, a coupling interface on the filling line intended to be coupled to a pumping unit allowing for the displacement of the liquid between the feed source and the container.
