Publication number: 20230355861Abstract: 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.Type: ApplicationFiled: May 1, 2023Publication date: November 9, 2023Inventors: Ben Alan Askem, Iacopo Claudio Ferrari, Matteo Foini, Paolo Forzani, Christopher John Fryer, Allan Kenneth Frazer Grugeon Hunt, Christian Riva
