Abstract
An apparatus for infusion monitoring including a pressure transmission line branched from the infusion hose and a diaphragm connected with the infusion hose, the diaphragm being able to be connected with a pressure sensor for registering a change in curvature of the diaphragm. In order to achieve the aim of providing an apparatus of this type which renders possible on the one hand a reliable monitoring of infusion and on the other hand a way of preventing the production of a false alarm in a substantially reliable fashion, the apparatus of this type is so designed that in the infusion hose between the branch point of the pressure transmission line and the free end, adjacent to the patient, of the infusion hose a one-way valve is arranged, which permits a direction of flow to the patient.
