Abstract:
1. Vacuum system for endoscopic intracavitary intraluminal or intracorporeal vacuum therapy for aspirating body fluids, wound secretions or gases from a hollow space, such as a body cavity, a hollow organ, a tissue abscess or an intestinal lumen, in particular in creating of a temporary endoscopic closure of an intestinal lumen, the vacuum system comprising: a vacuum pump having a control input for receiving a control signal for control of its vacuum and having, on its negative pressure side, a connection for a vacuum drainage arrangement, and connected or connectable to the control input of the vacuum pump, a pressure regulating unit, having a test signal input for receiving at least one pressure test signal, which provides a measure for a pressure or negative pressure prevailing at the hollow space to be treated and which is designed, upon specification a) of a negative pressure at the hollow space to be treated, being selectable from a predefined negative pressure value interval, and b) of an evacuation period, the value of which, situated between 0.5and 5seconds, is selectable, the vacuum pump being designed, as a function of the control signal currently being applied to its control input, to generate a suction capacity determined by the control signal.
