A device for collecting and absorbing liquid, and a method of manufacturing an absorption and spreading layer intended for liquid

Claim 1

A device for collecting and absorbing liquid, particularly urine, comprising at least one absorption body (6, 7) of super-absorbent type which, upon absorption of liquid forms an expandable gel, the device (1) comprising a laminate composed of several layers, in which there is a first layer of substantially liquid-proof material (2) in combination with a second layer of material permeable to liquid (3), which form at least one space (4, 5) enclosing a first absorption body (6), a layer (8) having an open-celled structure arranged in a first said space (4) to spread the liquid over a first said absorption body (6) arranged in said first space (4) to avoid gel blocking, the layer (8) of open-celled structure consisting of a substantially elastic non-absorbent material wherein the liquid-proof material (2) consists of a plastic layer (9) constituting one side of the multi-layer laminate and wherein the material (3) permeable to liquid consists of a non-wove fabric constituting the other side of the laminate, the first said absorption body (6) and the elastic material (8), which consists of a foam plastic being enclosed in the space (4) therebetween, a second absorption body (7) which is provided between the non-woven fabric (3) and the first said absorption body (6), and an inner, substantially liquid-proof third layer (10) which is arranged at least partially between the layer (8) of open-celled structure and the liquid-permeable layer (3), to form a second space (5) holding said second said absorption body (7), characterized in that an opening or recess (11) extends through the second said absorption body (7) and the inner, liquid-proof layer (10).
