Abstract: A device for separating gas bubbles from a liquid flow, having a degassing chamber with an inlet conduit and an outlet conduit for conducting the liquid flow and having a collecting chamber that communicates with the degassing chamber and having a gas outlet opening for the gas bubbles, wherein the degassing chamber includes a ring conduit that extends in an arc shape in a vertical plane and connects the inlet conduit to the outlet conduit in a flow direction and the collecting chamber is positioned in a vertically upper region of the ring conduit. A corresponding method for separating gas bubbles from a liquid flow is also disclosed.

Abstract: The invention relates to a medical high-pressure injector for injecting a liquid provided in a syringe (2.1, 2.2) into a patient, wherein the injector has at least one syringe holder (10) with an associated drive unit for the syringe (2.1, 2.2) held therein as well as connecting lines for transmitting the liquid from the syringe (2.1, 2.2) into a patient tube and/or for filling the syringe (2.1, 2.2) that is held in the syringe holder (10), wherein the connecting lines are embodied in an interchangeable control cassette (3) and the injector has a cassette holder (11) with a receiving chamber (110) that can be opened and closed, into which the control cassette (3) can be inserted.

Abstract: A syringe for a high-pressure injector, having a syringe cylinder with a tube connection for a tube line located at an end closer to the patient and having a plunger that is guided inside the syringe cylinder in an advancing direction and that has sealing surfaces for resting in a sealed fashion against an inner wall of the syringe cylinder. The plunger is embodied as a two-component injection-molded part based on thermoplastic plastic with a core piece composed of a harder plastic and a covering layer that is mounted on the core piece and is composed of a comparatively softer material. The covering layer constitutes or forms at least the sealing surfaces and the plunger surface of the plunger oriented toward the end of the syringe cylinder closer to the patient. The plunger is embodied with or has openings in the region of its plunger surface.
