摘要： The present invention relates to a method of determining a blockage condition in a negative pressure wound therapy system during a negative pressure wound therapy. Said method includes generating a negative pressure at a wound site by means of an electrical pump, recording the negative pressure, venting the fluid path of the negative pressure wound therapy system by opening a relief valve, closing the relief valve, determining and recording a negative pressure gradient occurring during the entire ventilation step, reactivating the electrical pump, determining and recording a number of pump turns, which are required to reestablish the negative pressure, and generating a first or a second blockage detection data set. The methods further includes executing a classification algorithm which allows to discriminate an unblocked condition of the negative pressure wound therapy system from a blocked condition of the negative pressure wound therapy system using the generated data sets. The invention further relates to a negative pressure wound therapy system adapted to execute said method of determining a blockage condition in a negative pressure wound therapy system.

摘要： The invention relates to a method of generating a negative pressure at a wound site during a negative pressure wound therapy. The method comprises the steps of setting a target negative pressure on a negative pressure wound therapy system, determining a negative pressure value by means of a pressure sensor, calculating a difference between the determined negative pressure value and the target negative pressure setting to obtain a negative pressure error, determining a target negative pressure gradient by means of a first function, and adjusting a control signal for the electrical pump in response to the value of the target negative pressure gradient, said control signal controls the speed of the electrical pump. The invention further relates to a negative pressure wound therapy system adapted to execute said method of generating a negative pressure at a wound site.
