Abstract
An article 1 comprises a hydrophilic foam layer 3; a reservoir cover 5 in contact with a first main surface of the hydrophilic foam layer 3, the reservoir cover 5 enclosing a reservoir cavity 7 together with the first main surface of the hydrophilic foam layer 3, the reservoir cavity 7 being for containing a fluid; and a hydrophobic foam layer 9 formed over the first main surface of the hydrophilic foam layer 3 and the reservoir cover 5. Fluid can be dispensed from the reservoir cavity 7 through a lower surface of the hydrophilic foam layer 3 by pressing on the hydrophobic foam layer 9 so that the reservoir cover 5 is compressed.
Claims13
An article comprising:
- a hydrophilic foam layer configured to be placed into contact with the skin of a patient;
- a reservoir cover in contact with a first main surface of the hydrophilic foam layer, the reservoir cover enclosing a reservoir cavity between the reservoir cover and the first main surface of the hydrophilic foam layer, the reservoir cavity being for containing a fluid;
- and a hydrophobic foam layer formed over the first main surface of the hydrophilic foam layer and the reservoir cover;
- wherein the reservoir cover has one or more side walls in contact with the first main surface of the hydrophilic foam layer, wherein the one or more side walls are inclined relative to a normal line of the first main surface, and wherein the reservoir cavity is enclosed between a top of the reservoir cover, the side walls of the reservoir cover and the first main surface of the hydrophilic foam layer.
