Assembly for treating wounds
The invention relates to an assembly for treating wounds and to a hand held unit for treating wounds. The assembly and the hand held unit comprise a device for producing a plasma and/or an excited gas or gas mixture by means of a piezoelectric transformer, which is housed together with a circuit board in a housing of the device, and the assembly comprises an expansion element. A control circuit, to which the piezoelectric transformer is electrically connected, is realized on the circuit board. A second end of the expansion element surrounds a wound region to be treated. A first end of the expansion element is detachably connected to the housing of the device at the opening of the housing. The produced plasma and/or excited gas or gas mixture thus enters the expansion element from the opening of the housing.
1. An assembly for treating wounds having a device for generating a plasma and/or an excited gas or gas mixture, wherein the device comprises:
a housing;
a piezoelectric transformer arranged in the housing;
a circuit board arranged in the housing, the circuit board including a control circuit, to which the piezoelectric transformer is electrically connected;
an opening formed in the housing towards which a high voltage end of the piezoelectric transformer is directed;
a fan arranged in or at the housing to provide a flow of air within the housing towards the opening, wherein the plasma and/or the excited gas or gas mixture, respectively, generated with the device exits from the opening; and,
an expansion element, including:
a first end removably connected to the housing at the opening; and,
a second end arranged to surround a wound region to be treated, wherein a cross-sectional area of the second end is larger than a cross-sectional area of the first end.
2. The assembly as recited in claim 1 , wherein the expansion element further comprises a peripheral side surface including a plurality of perforations.
3. The assembly as recited in claim 2 , further comprising at least one flow guiding element arranged at an interior side of the peripheral side surface, so that a flow of the plasma and/or the excited gas or gas mixture, respectively, is directed at the wound region to be treated.
4. The assembly as recited in claim 1 , further comprising a refeed arranged to connect the expansion element and the device.
5. The assembly as recited in claim 1 , wherein the expansion element further comprises a color sensor operatively arranged to indicate, by a change of color, that the treatment is completed.
6. The assembly as recited in claim 1 , wherein the expansion element further comprises a RFID-chip, so that via the type of the expansion element and in connection with the device, at least a duration of the treatment is settable.
7. The assembly as recited in claim 1 , wherein the expansion element further comprises an ozone-sensor.
8. The assembly as recited in claim 1 , wherein each of the plurality of perforations comprises a respective filter.
9. A hand held unit for treating wounds having a device for generating a plasma and/or an excited gas or gas mixture, wherein the device comprises:
a housing;
a piezoelectric transformer arranged in the housing;
a circuit board arranged in the housing, the circuit board including a control circuit, to which the piezoelectric transformer is electrically connected;
an opening formed in the housing towards which a high voltage end of the piezoelectric transformer is directed;
a fan arranged in or at the housing to provide a flow of air within the housing toward the opening, wherein the plasma and/or the excited gas or gas mixture, respectively, generated with the device exits from the opening; and,
an expansion element, including:
a first end detachably connected to the housing at the opening; and,
a second end arranged to surround a wound region to be treated.
10. The hand held unit as recited in claim 9 , wherein the expansion element further comprises a peripheral side surface including a plurality of perforations.
11. The hand held unit as recited in claim 10 , further comprising at least one flow guiding element arranged at an interior side of the peripheral side surface, so that a flow of the plasma and/or the excited gas or gas mixture, respectively, is directed toward the wound region to be treated.
12. The hand held unit as recited in claim 9 , further comprising a refeed arranged to connect the expansion element and the device.
13. The hand held unit as recited in claim 9 , wherein the expansion element further comprises a color sensor operatively arranged to indicate, by a change of color, that the treatment is completed.
14. The hand held unit as recited in claim 9 , wherein the expansion element further comprises a RFID-chip, so that via the type of the expansion element and in connection with the device, at least a duration of the treatment is settable.
15. The hand held unit as recited in claim 9 , wherein the expansion element further comprises an ozone-sensor.
16. The hand held unit as recited in claim 9 , wherein each of the plurality of perforations comprises a respective filter.
17. The hand held unit as recited in claim 9 , wherein:
a first cross-section taken proximate the first end has a first cross-sectional area; and,
a second cross-section taken proximate the second end has a second cross-sectional area, the second cross-sectional area being greater than the first cross-sectional area.
