  • Patent number: 10195329
    Abstract: A method of providing a concentrate of a dissolved substance for producing a dialysis solution includes providing a container containing a solid to be dissolved, supplying water into the container for dissolving the solid, draining the concentrate of the dissolved substance from the container and topping up with water, measuring the concentration of the dissolved substance or of a parameter correlated with the concentration, and temporary or permanent suppression of the topping up of water into the container. The suppression is effected when the measured concentration value of the dissolved substance falls below a first limit value or the value of the parameter falls below or exceeds a first limit value or when the change in the concentration value of the dissolved substance or of the value of the parameter exceeds a first limit value.

  • Patent number: 9950104
    Abstract: A method of rinsing and/or filling a blood treatment device, in particular for priming a blood treatment device, is associated with a blood treatment device that includes a membrane filter, in particular a hollow fiber membrane filter, a first partial circuit, and a second partial circuit. The first and the second partial circuits are separated by the membrane filter in a semipermeable manner, with temporarily the first partial circuit being first filled with a fluid with a uniform and/or a pulsatile first volumetric flow rate, with the volumetric flow rate not exceeding a specified threshold value at which the fluid has not completely wetted and/or soaked the membrane. The second partial circuit is temporarily open towards the atmosphere, air is displaced from the first partial circuit into the second partial circuit via the membrane, and during filling no negative pressure is applied to the first partial circuit.

  • Patent number: 9238098
    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.

  • Patent number: 8409127
    Abstract: A method for emptying a blood tubing set of a blood treatment device that includes an extracorporeal blood circuit with a membrane filter includes supplying air or gas to the blood tubing set to displace liquid therein. The blood tubing set includes arterial and venous patient blood tubes in communication with a first chamber of the membrane filter. The device also includes a substituate line which opens into the arterial blood tube and/or into the venous blood tube, and a substituate pump. To empty the blood tubing set, the arterial blood tube and the venous blood tube are connected to one another to provide a circuit that includes the membrane filter, the arterial blood tube, and the venous blood tube. The substituate line is disconnected, and the air or gas is pumped into the blood tubing set so as to displace liquid into a second chamber of the membrane filter.
