Abstract

Disclosed embodiments relate to apparatuses for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus comprises a wound dressing. The wound dressing can include a backing layer configured to cover a wound and be positioned over a skin surface surrounding the wound and a dressing display positioned on or underneath the backing layer and facing away from the skin surface. In some embodiments, the dressing display can be configured to be in electrical communication with one or more sensors configured to be positioned within the wound and a controller configured to capture information about the condition of the wound from the sensors and display the captured information on the dressing display.

First claim

1 . A negative pressure wound therapy apparatus, comprising:
a wound dressing comprising:
a backing layer configured to cover a wound and be positioned over a skin surface surrounding the wound; and
a dressing display positioned on or underneath the backing layer and facing away from the skin surface;
wherein the dressing display is configured to be in electrical communication with one or more sensors configured to be positioned within the wound and a controller configured to capture information about the condition of the wound from the one or more sensors and display the captured information on the dressing display.

2 . The apparatus of claim 1 , further comprising the one or more sensors configured to be positioned on or within the wound dressing, the one or more sensors configured to provide information about the condition of the wound to the controller.

3 . The apparatus of claim 1 , further comprising the controller positioned within or on the wound dressing.

4 . The apparatus of claim 1 , further comprising the controller positioned remote from the wound dressing.

5 . The apparatus of claim 1 , wherein the controller is configured to process the information provided by the one or more sensors and display the information on the dressing display.

6 . The apparatus of claim 1 , wherein the dressing display is a flexible organic light emitting diode display or e-ink display.

7 . The apparatus of claim 1 , wherein the one or more sensors are configured to measure one or more of temperature, pH, oxygen, carbon dioxide, conductivity, inductance, lactate, metallomatrix proteases, growth factors, optical absorption, optical reflectance, or infection.

8 . The apparatus of claim 1 , wherein the captured information comprises an image of the wound, and the controller is configured to display on the dressing display the image of the wound.

9 . The apparatus of claim 1 , further comprising a negative pressure source configured to apply negative pressure to the wound.

10 . The apparatus of claim 1 , further comprising a wound contact layer configured to be positioned in contact with the wound.

11 . The apparatus of claim 10 , further comprising one or more superabsorbent layers positioned between the wound contact layer and the backing layer.

12 . The apparatus of claim 10 , further comprising a spacer layer between the wound contact layer and the backing layer.
