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.
