A method for detecting occlusions including providing a signal that characterizes a conveying status of a fluid, and determining from a difference between two such signals whether an occlusion has occurred. The invention encompasses a device for detecting an occlusion including a sensor for sensing

A method for detecting occlusions including providing a signal that characterizes a conveying status of a fluid, and determining from a difference between two such signals whether an occlusion has occurred. The invention encompasses a device for detecting an occlusion including a sensor for sensing a fluid flow parameter and/or an operational parameter of the device and an evaluation unit for processing the output of the sensor.

The invention claimed is: 1. A method for detecting an occlusion, said method comprising the steps of:providing a signal that corresponds to a fluid pressure in at least one of an ampoule, a catheter, and a cannula of a fluid that is being at least one of infused, administered, and injected;filterin

The invention claimed is: 1. A method for detecting an occlusion, said method comprising the steps of:providing a signal that corresponds to a fluid pressure in at least one of an ampoule, a catheter, and a cannula of a fluid that is being at least one of infused, administered, and injected;filtering the signal, wherein filtering comprises modifying the signal by applying a transfer function to the signal such that a pressure rise between chronologically successive readings of the signal is limited; andcomparing the filtered signal and a reference signal,determining whether an occlusion in a flow path of the fluid has occurred based on a difference between the filtered signal and the reference signal.
