Abstract

Ein Handgerät zur Erzeugung von lokalem Unter- oder Überdruck hat ein Gehäuse, an dem ein Adapter vorgesehen ist, eine Pumpe, die über eine Leitung an den Adapter angeschlossen ist, einen Motor, mittels dem die Pumpe antreibbar ist, und eine Energieversorgungseinheit, durch die der Motor mit Energie versorgt wird. Um ein derart gestaltetes Handgerät leichter handhaben und bewegen zu können, wird vorgeschlagen, daß die Pumpe und der Motor innerhalb des Gehäuses des Handgeräts angeordnet werden.
