The present disclosure generally relates to a mobile negative pressure wound therapy (NPWT) device comprising a negative pressure pump, where the NPWT device is adapted to generate an alarm signal in case of an abnormal operation of the NPWT device. The present disclosure also relates to a corresponding method for operating such an NPWT device and a thereto related computer program product.

Mobile negative pressure wound therapy device

The present disclosure generally relates to a mobile negative pressure wound therapy (NPWT) device comprising a negative pressure pump, where the NPWT device is adapted to ensure that an operation of the negative pressure pump is terminated if the NPWT device is operating outside of a predefined operational range. The present disclosure also relates to a corresponding method for operating such an NPWT device and a thereto related computer program product.

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.
