  • Patent number: 11400426
    Abstract: Systems and apparatuses for preparing a medical fluid are disclosed. In an example embodiment, a system is configured to initially control a dosing of a first concentrate, while not feeding a second concentrate, under feedback control via a concentration sensor to a first pump to feed the first concentrate. When a concentration has reached a preselected concentration level, a value for a feeding parameter for the first pump to feed the first concentrate is determined. Additionally, the system is configured to control the dosing of both the first and the second concentrates by switching the feedback control via the concentration sensor, from control of the first pump to control of a second pump to feed the second concentrate. During this time, the system controls the first pump to feed the first concentrate based on the determined value of the feeding parameter.

  • Patent number: 9636445
    Abstract: An ambulatory ultrafiltration device includes a blood filter that has a blood side or fluid communication with the vascular system of the subject, an ultrafiltrate side, and a semipermeable membrane disposed between the blood side and the ultrafiltrate side. The ambulatory ultrafiltration also includes a buffer vessel in fluid communication with the blood side of the blood filter, and a blood pump. The blood pump is controlled to alternate between a withdrawal phase and a return phase. In the withdrawal phase, blood is withdrawn on a blood path from the subject via the blood filter to the buffer vessel. In the return phase, blood is returned from the buffer vessel to the subject on the blood path. The blood filter is arranged to remove ultrafiltrate from the blood during at least one of the withdrawal and return phases.

  • Patent number: 9623165
    Abstract: A cassette is provided for installation in a dialysis monitor to pump a treatment solution through a dialyzer. The cassette is a unitary component with a hydraulic manifold (53) and a pneumatic manifold (54) integrated into a body (52). The body (52) has connectors for connecting the hydraulic manifold (53) to the dialyzer and the pneumatic manifold (54) to a pneumatic pressure source. A set of solution pumps is integrated in the cassette, and each solution pump includes a pump cavity inside the body. The solution pumps are operable to displace the treatment solution through the hydraulic manifold (53) to and/or from the dialyzer by action of a reciprocating gas-liquid interface in the pump cavity (30) of the respective solution pump. The gas-liquid interface is formed directly between a gaseous substance and the treatment solution.

  • Patent number: 9572920
    Abstract: A disposable for use in blood treatment including a blood treatment unit and two membrane pumps connected in parallel on one side of the blood treatment unit. The disposable is operable in a single-needle mode, in which the pumps generate a pulsatile flow of blood through the blood treatment unit, and in a double-needle mode, in which the pumps generate an essentially continuous flow of blood through the blood treatment unit. The pumps connect to a supply of treatment fluid such that alternating flows of treatment fluid causes the pumps to generate the desired flows of blood in the single-needle and double-needle modes. The treatment fluid may be used as motive fluid for displacing the blood in the membrane pumps and/or as control fluid for controlling opening and/or closing of upstream and downstream commutation valves in the membrane pumps.

  • Publication number: 20160082175
    Abstract: A heat exchanger comprises a first and a second fluid circuit extending through the heat exchanger. The heat exchanger further comprises a stack of fluid plates and a membrane arranged between each of the fluid plates where one interspace is formed between each fluid plate and membrane. The first and second fluid circuits are each constituted by a passage extending through the fluid plates and membranes and along the fluid plates and membranes in a least two interspaces. A primary fluid (W) is passed through the first fluid circuit and a secondary fluid (X) is passed through the second fluid circuit such that the primary fluid (W) is passed along one side of a membrane and simultaneously the secondary fluid (X) is passed along the other side of the membrane. Heat is thus exchanged between the primary fluid (W) and the secondary fluid (X) over the membrane.
