Abstract
The present invention provides for a novel epicutaneous test plaster useful for the application of liquid test substances for direct and continuous contact with the skin of a human patient. Further provided is a device useful for the sealing of the epicutaneous test plaster of the present invention, which enables the storage and transport of said test plasters preloaded with liquid test substances, prior to their application to the skin of a human patient.

Claims17
An epicutaneous test plaster comprising
- a support lattice comprised of a material impermeable to liquid and gas containing a first multiplicity of holes,
- a flexible carrier lattice containing a second multiplicity of holes,
- a first adhesive layer for removable adhesion of the epicutaneous plaster to a skin portion,
- a second adhesive layer for binding the support lattice to the flexible carrier lattice,
- a liquid and gas impermeable cover layer extending over all the first adhesive layer of said flexible carrier lattice, and
- a plurality of fluid absorbent material distributed over the support lattice;
- wherein the second multiplicity of holes on the flexible carrier lattice is greater than the first multiplicity of holes on the support lattice;
- wherein said flexible carrier lattice is adhered to the support lattice by way of the second adhesive layer;
- wherein the plurality of test chambers are formed by way of second multiplicity of holes in the flexible carrier lattice describing a frame around a contiguous portion of the support lattice;
- wherein a subset of the first multiplicity of holes on the support lattice align with the second multiplicity of holes in the flexible carrier lattice;
- wherein the liquid and gas impermeable cover layer forms a seal over the top of the plurality of test chambers;
- wherein the fluid absorbent material is located within said plurality of test chambers, said fluid absorbent material not in contact with either of said flexible carrier lattice or liquid and gas impermeable cover layer;
- and
- wherein the liquid and gas impermeable cover layer is removably secured to the flexible carrier lattice by way of said first adhesive layer.
