Abstract

See full text

A mobile negative pressure wound therapy (NPWT) device is described having an inlet to be in fluid flow connection with a wound site; a canister in fluid flow connection with the inlet for collection of liquid from the wound site; a pump in fluid flow connection with the canister for establishing a negative pressure in the canister; a pressure sensor arranged to sense a pressure in the canister; and control circuitry for controlling operation of the NPWT device. The control circuitry is configured to: initiate a test sequence for the NPWT device; acquire a first signal indicating the pressure in the canister; evaluate the first signal; when the acquired first signal indicates a pressure less negative than a predefined threshold pressure: control the pump to operate during a predefined time period; acquire a second signal after the predefined time period; proceed with the start-up test sequence; and when the acquired signal indicates a pressure more negative than the predefined threshold pressure: proceed with the start-up test sequence without controlling the pump to operate during the predefined time period.
