Abstract
An electrotechnical core for generating a cold atmospheric pressure or low-pressure plasma for the treatment of human, animal, or technical surfaces. The core has a side facing the surface and a side facing away from the surface and comprises the following layers, starting from the side facing the surface: a first insulation layer,a first electrode structure with a first contact between the first electrode structure and a power supply unit,a second insulation layer to galvanically isolate the first electrode structure and a second electrode structure from one another,wherein the second electrode structure is driven during operation by a voltage signal sufficient to ignite a plasma,a third insulation layer to galvanically isolate the second electrode structure from a third electrode structure,wherein the third electrode structure grounds the third electrode structure during operation.
Core Innovation
The invention relates to a power supply unit and a plasma applicator for generating a cold atmospheric pressure or low-pressure plasma for the treatment of human and/or animal and/or technical surfaces. The plasma applicator comprises an electrotechnical core having a side facing the surface to be treated and a side facing away from the surface to be treated, with layers arranged above one another starting from the side facing the surface to be treated.
A first insulation layer is arranged adjacent to a first electrode structure with a first contact for establishing electrical contact with a power supply unit, wherein the first electrode structure is grounded during operation. A second insulation layer galvanically isolates the first electrode structure from a second electrode structure, and the second electrode structure has a second contact for electrical contact to the power supply unit and is driven during operation by a voltage signal supplied by the power supply unit and sufficient to ignite a plasma.
A third insulation layer galvanically isolates the second electrode structure from a third electrode structure, wherein the third electrode structure has a third contact to ground the third electrode structure during operation. Means for ensuring single use are provided by a memory configured to store a special code or hash value, and the power supply unit is configured to check whether the plasma applicator has already been used or whether it is suitable for a certain plasma treatment.
Claims Coverage
The independent claim covers a layered electrotechnical core with three insulation layers and three electrode structures, including grounded first and third electrode structures and a driven second electrode structure that ignites cold atmospheric pressure or low-pressure plasma for treating human/animal/technical surfaces. It also covers single-use ensuring with memory-based special code or hash checking and suitability checking by the power supply unit.
Layered electrotechnical core for plasma ignition
An electrotechnical core having a side facing the surface to be treated and a side facing away from the surface to be treated, with layers arranged above one another starting from the side facing the surface to be treated: a first insulation layer, a first electrode structure grounded during operation, a second insulation layer galvanically isolating the first electrode structure from a second electrode structure, and a third insulation layer galvanically isolating the second electrode structure from a third electrode structure, wherein the second electrode structure is driven during operation by a voltage signal sufficient to ignite a plasma and the third electrode structure is grounded during operation.
Single-use ensuring with memory-stored special code or hash
Means for ensuring single use of the plasma applicator, comprising a memory configured to store a special code or hash value.
Power supply unit checks prior use and suitability for certain treatment
A power supply unit configured to check whether a plasma applicator has already been used or whether the plasma applicator is suitable for a certain plasma treatment.
The core claim coverage centers on the layered electrotechnical core with grounded first and third electrode structures and a driven second electrode structure igniting cold atmospheric pressure or low-pressure plasma, combined with single-use ensuring implemented via memory-stored special code or hash values that a power supply unit checks for prior use and suitability for a certain plasma treatment.
Stated Advantages
Insulating the treatment from external influences while leaving the plasma applicator on the wound.
Ensuring single use of the plasma applicator.
Checking whether a plasma applicator has already been used.
Checking whether the plasma applicator is suitable for a certain plasma treatment.
Documented Applications
Wound healing context in which a plasma applicator is applied to form a sealed gas space, plasma is ignited, and the applicator is left on the wound for days to weeks, including repeated plasma treatments.
Treatment of human and/or animal and/or technical surfaces with cold atmospheric pressure or low-pressure plasma.
