摘要： A device and method for treating a wound of a patient with negative pressure is provided. The device comprises a pump chamber that has at least one moveable side of the chamber. The moveable side moves between an intake stroke and an exhaust stroke upon application of an electrical potential. Fluid is drawn into the pump chamber during the intake stroke and expelled from the pump chamber during the exhaust stroke. The pump system may have a magnetic or a piezoelectric element that drives the movement of the pump chamber side.

摘要： A method and apparatus are disclosed for dressing a wound. The wound dressing includes a transmission layer having a first surface and a further surface spaced apart from the first surface by a relax distance in a relaxed mode of operation. A plurality of spacer elements extend between the first and further surfaces and, in a forced mode of operation, are locatable whereby the first and further surfaces are spaced apart by a compression distance less than the relax distance.

摘要： 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.

摘要： Systems and methods for controlling a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes causing provision of negative pressure, via a flow path, to a wound dressing configured to be positioned over a wound, the flow path configured to fluidically connect the pump system to the wound dressing, measuring a first pressure value in the flow path at a first time, measuring a second pressure value in the flow path at a second time, calculating a first rate of pressure change using the first and second pressure values, and in response to determining that the calculated first rate of pressure change satisfies a threshold rate of change, providing an indication that the wound dressing is full, wherein the method is performed under control of a controller of the pump system.
