Abstract
A device (10) for disinfecting wound treatment is described, with a housing (18), with a plasma generator (54) arranged in housing (18) for generating a disinfecting plasma, with a flow module (52) arranged in housing (18) for generating a gas stream, which forms a free jet (32) transporting the disinfecting plasma from housing (18), and with a jet control unit (50) for affecting the free jet (32) in a planned manner by controlling the gas stream generated by flow module (52). Means (10) has, furthermore, a guide apparatus (56) controllable via the jet control unit (50) for guiding the free jet (32).
Claims19
A device for disinfecting wound treatment, the device comprising:
- a housing;
- a plasma generator arranged in said housing for generating a disinfecting plasma;
- a flow module arranged in said housing for generating a gas stream, which forms a free jet transporting the disinfecting plasma from said housing;
- a guide apparatus for guiding the free jet;
- and
- a jet control unit controlling said guide apparatus for affecting the free jet in a planned manner by controlling the gas stream generated by said flow module, wherein:
- said guide apparatus has at least one guide element arranged at a gas discharge opening of said housing, said guide element being variably positionable relative to the housing;
- said jet control unit controls said guide apparatus by varying a position of said variably positionable guide element relative to the housing for affecting the free jet in a planned manner by controlling the gas stream generated by said flow module;
- and
- said jet control unit controls said guide apparatus for varying, with the guide apparatus, at least one of a jet cross section of the free jet being discharged from housing and a direction of discharge, relative to the housing, of the free jet being discharged from the housing.

A device for disinfecting wound treatment, the device comprising:
- a housing with a gas intake opening and a gas outlet opening;
- a flow module operatively connected to said housing for generating a gas stream;
- a plasma generator operatively connected to said housing for generating a disinfecting plasma that is transported by the gas stream;
- a guide apparatus for guiding the gas stream as a free jet discharged from said gas outlet opening and transporting the disinfecting plasma from said housing;
- and
- a jet control unit controlling said guide apparatus by controlling the gas stream generated by the flow module, the jet control unit controlling a position of the guide apparatus relative to the housing and the guide apparatus acting on the gas stream generated by the flow module, as the gas stream is discharged from the housing for affecting a free jet by varying at least one of a jet cross section of the free jet and a direction of discharge of the free jet, relative to the housing, in a controlled manner.
