## Abstract

The present invention relates to a system for treatment of skin wounds, comprising an energy source for activation of a biochemical healing effect, and at least one dressing intended to be placed on the wound before the step of activation by said energy source, characterized in that said dressing comprises an identification means interacting in a contactless manner with a sensor that triggers the function of the energy source only when the distance between the sensor and said identification means is below a threshold value.

## Claims

### Claim 1

A dressing for use in a skin wound treatment system, the system comprising the dressing, a laser source for activating a biochemical wound-healing effect, a calculator and a sensor, wherein the laser source is at least partially controlled by the calculator, which receives a signal from the sensor, the dressing including:
a radio frequency identification (RFID) tag having an induction loop configured to interact without contact and without electrical connection with the sensor; and
a circuit including a memory,
wherein:
the dressing is configured for affixation on or adjacent a wound prior to activation of the laser source;
the induction loop provides power to the circuit, and
a dressing type identifier is recorded in the memory and used to control the power, duration and frequency of pulses of the laser source.

### Claim 2 (depends on 1)

The dressing of claim 1, wherein the RFID tag includes a unique identifier for the dressing type associated with it.

### Claim 3 (depends on 1)

The dressing of claim 1, wherein the dressing is formed of a transparent film.

### Claim 4 (depends on 3)

The dressing of claim 3, wherein the edges of the wound are brought together in close proximity and temporarily held in place, and wherein the transparent film is configured to transfer energy of the laser source to an area of the wound.

### Claim 5 (depends on 1)

The dressing of claim 1, wherein the dressing includes one or more coatings associated with the biochemical wound-healing effect activated by the laser source.
