1. A device (10) for supporting a treatment with pulsed electric fields for wound healing and/or for inactivating microorganisms, comprising
an electrical energy storage (16),
a pulse generator (17) for providing electrical excitation pulses,
a transformer (26) for providing high-frequency electrical pulses (200) at an output side (28), wherein a first terminal of an input side (27) of the transformer (26) is connected to the pulse generator (17), and
a treatment instrument (100) comprising a body (102) made of an electrically insulating material and an electrode (110) arranged inside the body (102),
wherein a gas or gas mixture is accommodated inside the body (102) and the treatment instrument (100) is configured for gas discharge upon electrical excitation,
wherein a first end (103) of the treatment instrument (100) is configured for coupling to a first terminal of the output side (28) of the transformer (26),
wherein a second end (104) of the treatment instrument (100) is configured to contact surfaces and/or biological tissue, and that a second terminal of the output side (28) of the transformer (26) is connected to a second terminal of an input side (27) of the transformer (26),
wherein the transformer (26) and the pulse generator (17) are configured in such a way that the high-frequency electrical pulses (200) have a pulse repetition rate in the range from 100 Hz to 400 Hz,
wherein the treatment instrument (100) is configured to conduct the generated high-frequency electric pulses (200) or their electric fields to an object to be treated or to an organic or biological material to be treated,
wherein said body (102) is a closed body (102),
wherein the device comprises a housing and a housing shield (13) to which said second terminal of the output side (28) of the transformer (26) is connected,
wherein the housing shield (13) is electrically insulated from the outside world by a housing of the device (10) and thus is configured as a floating ground,
wherein the pulse generator (17) is configured in such a way that the high-frequency electrical pulses (200) have a frequency in the range from 10 kHz to 100 KHz.
