Abstract

The present invention relates to a method of determining a canister full condition in a negative pressure wound therapy system during a negative pressure wound therapy. Said method includes determining and recording a number of pump turns associated with an electrical pump used for generating a negative pressure in the negative pressure wound therapy system, determining and recording a plurality of negative pressure values by means of a pressure sensor, calculating and recording a negative pressure variation score by means of the recorded negative pressure values, and generating a first or a second canister full detection data set. Moreover, the method includes executing a classification algorithm which allows to discriminate a canister not full condition from a canister full condition of the negative pressure wound therapy system using the generated data sets. The invention further relates to another method of determining a canister full condition in a negative pressure wound therapy system during a negative pressure wound therapy. Said further method includes generating a negative pressure at a wound site by means of an electrical pump, generating a first or a second canister full detection data set, and executing a classification algorithm, which allows to discriminate a canister not full condition from a canister full condition of the negative pressure wound therapy system using the generated data sets, whereby the classification algorithm includes a support vector machine. The invention further relates to a negative pressure wound therapy system adapted to execute said methods of determining a canister full condition a negative pressure wound therapy system.
