WOUND CARE DEVICE FOR TREATING WOUNDS BY MEANS OF SUBATMOSPHERIC PRESSURE

1 . A wound care device for treatment of wounds by means of subatmospheric pressure in the wound area, the wound care device comprising:

at least one wound covering element, and

at least one device for generating subatmospheric pressure placed on the wound covering element.

2 . A wound care device according to claim 1 , further comprising at least one absorption body to absorb the wound exudations.

3 . A wound care device according to claim 1 , further comprising at least one reservoir for collecting wound exudations.

4 . A wound care device according to claim 1 , further comprising a liquid-permeable wound contact layer facing the wound.

5 . A wound care device according to claim 2 , further comprising a barrier disposed between the device for creating subatmospheric pressure and the absorption body for absorbing the wound secretions, where the barrier is configured to prevent liquids from flowing to the device for creating subatmospheric pressure.

6 . A wound care device according to claim 1 , where:

the device for creating subatmospheric pressure is arranged on the side of the wound covering element away from the wound.

7 . A wound care device according to claim 1 , where:

the device for creating subatmospheric pressure has at least one pump.

8 . A wound care device according to claim 1 , where:

the device for creating subatmospheric pressure has a plurality of pumps in parallel or in series.

9 . A wound care device according to claim 1 , further comprising:

at least one battery selected from a group consisting of:

traditional disposable batteries,

traditional rechargeable batteries,

arrays of small batteries, preferably “button cells,” and

flexible, rechargeable storage batteries.

10 . A wound care device according to claim 1 , where:

the device for creating subatmospheric pressure is arranged directly on the wound covering element

11 . A wound care device according to claim 1 , further comprising:

a connection site for an outside power supply.

12 . A wound care device according to claim 1 , further comprising:

a coupling, a check valve, a three-way cock, or any combination thereof arranged between the device for creating subatmospheric pressure and the wound covering element.

13 . A wound care device according to claim 2 , further comprising:

a coupling, a check valve, a three-way cock, or any combination thereof arranged between the device for creating subatmospheric pressure and the absorption body for absorbing the wound exudations.

14 . A wound care device according to claim 1 , further comprising:

a sensor for at least one physiological and/or pathological parameter of the wound exudation.

15 . A wound care device according to claim 1 , where the wound covering element includes a means for fastening the device for creating subatmospheric pressure.

16 . A wound care device according to claim 2 , where the absorption body includes a fleece containing cellulose fibers.

17 . A wound care device according to claim 1 , where the device for creating subatmospheric pressure is configured to generate excess pressures in a reversed operating mode.

18 . A wound care device according to claim 1 , further comprising:

means of dispensing medications.

19 . A wound care device according to claim 1 , further comprising:

means for introducing flushing medium.

20 . A method for treating a wound using a wound care device comprising at least one wound covering element and at least one device for generating subatmospheric pressure placed on the wound covering element, the method comprising:

generating a given partial vacuum using the device for generating subatmospheric pressure;

switching off the device for creating subatmospheric pressure; and

when a partial vacuum threshold is crossed, switching on the device for creating subatmospheric pressure to generate a given partial vacuum.
