Patent ID: 10828403

Abstract:
Disclosed embodiments relate to apparatuses and methods for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus includes one or more indicators configured to illuminate in a pattern to communicate at least one of a status of a pump assembly and/or of a dressing. The pattern is configured to enable an electronic device comprising at least one camera to capture the illumination pattern of the one or more indicators and to determine the status corresponding to the pattern of illumination. In some embodiments, a negative pressure wound therapy apparatus is powered by an energy generator that has a first side configured to be in contact with a skin surface of a patient and a second side configured to be exposed to atmosphere, and the energy generator is configured to utilize a temperature differential between the skin surface and the atmosphere to generate electrical energy to power the apparatus. In some embodiments, a negative pressure wound therapy apparatus is powered by an energy harvester that utilizes radio frequency spectrum to power one or more components of negative pressure wound therapy apparatus. In certain embodiments, a negative pressure wound therapy apparatus includes one or more RF energy harvesters to power a pump assembly.
