Abstract
In order to be able to regulate in a simple and reliable manner the quantity of liquid that is administered to a patient through a hose in an infusion device, there is provided, according to the invention, a motor-driven eccentric, which presses the hose against a blocking device and clamps it off to a greater or lesser degree. The blocking device forms a part of at least one guide for the hose and can assume two positions. In one of the positions the guide is released; in the other position it is closed. A lever mounted with freedom to rotate, which can be spring-loaded, is particularly well suited for the blocking device. In addition, a clamping lever which can be activated through an electromagnetic latch, can be provided as an emergency stop.
