Abstract

The present invention relates to a method of determining a leakage condition in a negative pressure wound therapy system during a negative pressure wound therapy. Said method includes controlling an electrical pump for generating a negative pressure and generating a leakage signal if a pump speed associated with the electrical pump exceeds a predetermined value. The present invention further proposes a method of estimating a flow rate of a negative pressure wound therapy system. The further method of estimating a flow rate comprises the steps of controlling an electrical pump for generating a negative pressure and estimating the flow rate as a flow rate function of a pump speed and a pump current. The invention further relates to a negative pressure wound therapy system adapted to execute the method of determining a leakage condition a negative pressure wound therapy system and/or the further method of estimating a flow rate of a negative pressure wound therapy system.
