Abstract
The invention relates to electrically-heatable plasters which comprise a self-adhesive skin contact layer, an electrically-conductive textile fabric in which electrically-conductive fibres are in contact with one another, as a heating element, and optionally at least one active substance, as well as to a method for production and the use of same for local heat therapy and/or transdermal application of active substances.
Claims8
A method for administration of heat to the skin of a patient comprising:
- applying an electrically heatable plaster having a self-adhesive skin contact layer comprising at least one pharmaceutical active substance;
- an electrically conductive, textile sheet comprising a fabric, a knitted structure, a crocheted structure, a braided structure, a bi-directional or multi-directional fabric, a felt, or a fleece of fibers, in which a plurality of electrically conductive fibers are in contact with one another;
- and
- wherein the electrically conductive textile sheet is provided with electrical contacts;
- and
- wherein the electrically conductive textile sheet constitutes a rear layer of the plaster;
- and
- applying the electrically conductive textile sheet, to a patient and closing a circuit between a voltage source and the electrically conductive textile sheet.
The method as claimed in 1, wherein the voltage source is a direct current source.
A method for administration of at least one pharmaceutical active substance comprising:
- providing an electrically conductive textile sheet comprising a fabric, a knitted structure, a crocheted structure, a braided structure, a bi-directional or multi-directional fabric, a felt, or a fleece of fibers, in which a plurality of electrically conductive fibers are in contact with one another, the electrically conductive textile sheet being provided with electrical contacts to provide an electrically heatable plaster having a self-adhesive skin contact layer comprising at least one pharmaceutical active substance, wherein the electronically conductive textile sheet constitutes the rear layer of the plaster, and including a step of applying the electrically heatable plaster to the skin of a mammal.
A method for administration of at least one pharmaceutical active substance comprising:
- providing an electrically heatable plaster having a self-adhesive skin contact layer comprising at least one pharmaceutical active substance;
- an electrically conductive, textile sheet comprising a fabric, a knitted structure, a crocheted structure, a braided structure, a bi-directional or multi-directional fabric, a felt, or a fleece of fibers, in which a plurality of electrically conductive fibers are in contact with one another;
- and wherein the electrically conductive textile sheet is provided with electrical contacts;
- and wherein the electrically conductive textile sheet constitutes a rear layer of the plaster;
- and wherein the at least one pharmaceutical active substance contained in the plaster is administered to a patient.
