Patent number: 9572920Abstract: 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.Type: GrantFiled: June 18, 2012Date of Patent: February 21, 2017Assignee: Gambro Lundia ABInventors: Olof Jansson, Mattias Holmer, Eddie Nilsson, Lennart Jonsson

Publication number: 20160082175Abstract: 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.Type: ApplicationFiled: December 4, 2015Publication date: March 24, 2016Inventors: Lennart Jonsson, Jan Sternby, Eddie Nilsson
