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 concerns a device for injecting a liquid product contained in a bag, the device comprising a housing consisting of two half-shells articulated about an axis of rotation in order to allow the relative movement of the half-shells relative to each other between: —an open position in order to put the bag in place and—a closed position for injecting the liquid product contained in the bag, remarkable in that: —one of the half-shells comprises a deformable bladder—called the “active bladder”—having a volume that varies under the action of a hydraulic ram supplying said bladder with hydraulic fluid, and—the other of the half-shells comprises a deformable damping cushion having a constant volume—called the “passive cushion”.

Abstract: The invention concerns an device for injecting a patient with a liquid product contained in a container (4), the system comprising a pressurizing unit for driving the liquid product contained in the container, the system further comprising a calculator for estimating the injection flow rate at the outlet of the container, said injection flow rate at the outlet being estimated on the basis of a law of deformation of the system under the effect of the pressure inside the container.

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.

Abstract: A casing (20) includes a casing body (30) defined by a pair of lateral wall portions (32a, 32b) which are symmetric about a longitudinal plane (P) to define an ovoid transverse cross-section. The casing includes a lower fitting (35) that is connected with a source (23) of motive liquid (22) under pressure. A deformable enclosure (38) is sealed to an upper edge flange (41) of the casing. The deformable enclosure is drawn open (FIG. 9b) against a grid or cage (44) to receive a flexible pouch (18) that contains a medical liquid (19). A length of flexible tubing (17) connected to the pouch extends through a passage (37) in a cover or stopper (46) which is received on the casing body with a fluid tight seal. Under further motive fluid pressure, the flexible pouch (18) is squeezed, forcing the medical liquid through the tubing (17, 15, 9) to a cannula or other injection device (3).
