Abstract

In an infusion set having a container for fluid medicines, which by a feed-line and a differential pressure valve is connected to a drip chamber and which by a further feed-line is connected to a front end controlled with a roller clamp according to U.S. Patent, 5,935,100, the differential pressure valve has two inlets each with an associated differential force chamber and the two differential force chambers are sealingly separated from each other by a diaphragm disk, sealingly separated from each other, wherein both differential force chambers are connected to an exit line for the fluid medicine. To use the differential pressure valve, the valve is configured as a 3-way check valve by the fact that the first inlet is connected to the container for the fluid medicine and that the second inlet is designed for the connection to a syringe or the like.
