Abstract

An apparatus and related aspects for providing negative pressure to a wound site are disclosed. The apparatus comprises a source of negative pressure configured to provide negative pressure via a first fluid flow path from an inlet of the source of negative pressure to a wound site, and an electronically controllable valve configured to release negative pressure from the wound site via a second fluid flow path. The apparatus further comprises a pressure sensor configured to measure a pressure level in the second fluid flow path, and control circuitry operatively connected to the source of negative pressure, the electronically controllable valve, and the pressure sensor. The control circuitry is configured to open the electronically controllable valve, and in response to a pressure change rate being above a pressure change rate value, output a signal indicative of a blockage in the second fluid flow path. The control circuitry is further configured to in response to the pressure change rate being below the pressure change rate value, close the electronically controllable valve and activate the source of negative pressure, and in response to the pressure level, as measured by the pressure sensor, being non-responsive to a change in negative pressure generated while the source of negative pressure is active, output a signal indicative of a blockage in the first fluid flow path.
