Abstract
A device for collecting and absorbing urine, comprising a laminate composed of several layers, in which an outer plastic casing in combination with a material permeable to urine form a space enclosing an absorption body. The absorption body includes at least one super-absorbent laminate which may be a tissue integrated with a super-absorbent polymer and which upon absorption forms a gel. The space surrounding the absorption body is designed to permit expansion when the absorption body assumes the gel phase.
