Abstract
Described is a novel epicutaneous test plaster useful for the application of test substances for direct and continuous contact with the skin of a human patient. The plaster comprises a support lattice with a flexible carrier lattice adhered thereto, the combination forming a series of test chambers capable of receiving test substances for application to the skin.
Claims12
An epicutaneous test plaster comprising
- A support lattice of absorbent paper adhered with a moisture barrier layer containing a first multiplicity of holes,
- A flexible carrier lattice containing a second multiplicity of holes, said flexible carrier lattice including an adhesive layer for removable adhesion of the epicutaneous plaster to a skin portion;
- a removable cover layer extending over all the adhesive layer of said flexible carrier lattice, and
- a plurality of test chambers distributed over the support lattice of absorbent paper adhered with a moisture barrier layer;
- wherein the second multiplicity of holes on the flexible carrier lattice is greater than the first multiplicity of holes on the support lattice of absorbent paper adhered with a moisture barrier;
- wherein said flexible carrier lattice is adhered to the support lattice on the side opposite to the moisture barrier layer;
- wherein the plurality of test chambers are formed by way of a first subset of the second multiplicity of holes in the flexible carrier lattice, wherein each hole of the first subset of the second multiplicity of holes describes a frame around a contiguous portion of the support lattice;
- wherein a second subset of the second multiplicity of holes in the flexible carrier lattice align with the first multiplicity of holes on the support lattice;
- and
- wherein the removable cover layer is removably secured by way of the adhesive layer of the flexible carrier lattice.
