    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.

    摘要： Apparatuses for use in negative pressure wound therapy are described herein. In some embodiments, the apparatus includes a pump assembly having a pump housing, a magnet, an electrically conductive coil, and a diaphragm, wherein the electrically conductive coil is configured to move a portion of the diaphragm to pump a fluid through the pump apparatus, and a dampener positioned within the pump assembly configured to reduce sound generated by the pump assembly during operation of the pump assembly. In some embodiments, the apparatus includes a housing having a first section and a second section, and an illumination source disposed within the housing adjacent the first section, wherein the illumination source is configured to illuminate the first section, wherein the first section is one of transparent and translucent, and wherein the first section is thinner than the second section as measured perpendicularly from inside to outside the housing. In some embodiments, the pump apparatus includes components configured to be laser welded together.
