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.

Abstract: The present invention provides an absorbent structure to be used in an absorbent article such as a diaper, a training pant, an adult incontinence absorbent article, a bed mat, or the like, and the respective absorbent article. The absorbent structure of the present invention is able to rapidly acquire urine even against gravity as is quantified by the liquid drip off test defined herein.
