Abstract: A method for reducing a bolus in a fluid guide unit, a forecast method, a safety device and a medical pump. The method for reducing a bolus includes detecting a pressure course in the fluid guide unit by a sensor unit, storing the pressure course in a memory unit; determining an occlusion probability by a control unit based on the pressure course, detecting a volume delivered by the pump for an operating range with high occlusion probability, which can be based on a detected number of motor steps of a pump motor or of a detected rotation angle of the pump motor, detecting an occurrence of an occlusion at a detection time by a detection unit when exceeding a pressure limit value, and pumping back the delivered volume for the operating range with high occlusion probability, in particular by retracting the detected motor steps or the detected rotation angle.

Abstract: An infusion system includes an infusion pump configured to convey a fluid to be administered through a fluid conduit, a number of sensors for producing associated sensor data, and an AI unit configured to calculate a number of target variables depending on the number of sensor data using a statistical model as a basis, the statistical model having been trained using training data.

Abstract: A pressure sensor device for internal pressure monitoring in a hose, preferably an infusion hose, that is used for fluid transmission and that rests directly or indirectly on a pressure sensor housing. The hose is elastically deformable and connected via a contact side to a pressure transmission element located in the pressure sensor housing. The pressure transmission element transmits internal pressure changes absorbed via the contact side to a compressive force sensor for measurement. The contact side can have an elliptical shape, and the pressure transmission element can have a funnel-shaped extension, to make the pressure sensor device as robust as possible in terms of measurement accuracy, and independent of fluctuations in temperature and associated changes in material states.
