CA 2691922
A method and apparatus are disclosed for determining a negative pressure generated by a suction pump of a topical negative pressure (TNP) system. The method includes the steps of disconnecting a drive voltage from a pump of the TNP system, determining an EMF generated by a free-wheeling element of the pump, selecting a new drive voltage for the pump and reconnecting the new drive voltage to the pump.
L'invention concerne un procédé et un appareil pour déterminer une pression négative générée par la pompe d'aspiration d'un système à pression négative topique (TNP). Le procédé comprend les étapes de déconnexion d'une tension de commande à partir de la pompe du système TNP, de détermination d'une force électromotrice générée par un élément tournant librement de la pompe, de sélection d'une nouvelle tension de commande pour la pompe et de reconnexion de la nouvelle tension de commande à la pompe.
