Abstract: The invention relates to an apparatus for supporting an operator in operating a medical device, comprising a signaling device (2, 20, 26, 9) for signaling a necessary operation of a component to be operated of the medical device, preferably by emitting a signal from the component to be operated and/or by orienting a signal onto the component to be operated. The invention further relates to a method for supporting an operator in operating a medical device, comprising the signaling of a necessary operation of a component to be operated of the medical device by emitting a signal from the component to be operated and/or by orienting a signal onto the component to be operated. Further, the invention relates to a single-use item for a medical device, preferably a single-use item for the medical device, with a component to be operated by an operator, wherein the component to be operated comprises a signaling device for emitting an optical, acoustical, and/or haptical signal.

Abstract: An apparatus and method for blood treatment for the single-needle mode, the apparatus having an extra-corporeal blood circuit with a blood infeed line running to the inlet and a blood return line leading away from the outlet, of a blood treating unit, includes in the blood return line a device, e.g., container, for amassing blood, which is in flow-permitting connection for gas transfer with a device, e.g., container, for storing gas. A pressure is calculated and set in the device for storing gas before the arterial and venous phases are started, with two constraints. First, the pressure should be sufficiently low to ensure both no infusion of air into the patient and also regulated flow of blood into the patient even at opposing pressures lower than ambient pressure. Second, the pressure should be sufficiently high to expel blood from the device for amassing blood into the device for storing gas.

Abstract: The present invention relates to a method for removing blood from an extracorporeal blood circuit and/or a functional device, each connectable or connected with a blood treatment apparatus for the purpose of blood treatment of a patient. The blood treatment apparatus of the method comprises or is connected with at least one extracorporeal blood circuit with a line having interior portions, the extracorporeal blood circuit comprising at least one arterial line section and at least one venous line section, wherein a first section of the arterial line section is configured to be connected with a second section of the venous line section, and further comprises at least one blood pump for conveying blood within the line interior portions. The method includes the step of operating the blood pump in a second conveying direction which is opposite to a first customary conveying direction. It further relates to corresponding apparatuses.
