A method of detecting an occlusion within a flexible infusion tube (16) by measuring samples indicative of pressures relative to instances in time. Difference values for the samples are created. The difference values are compared to percentages of other difference values. When appropriate, an occlusion signal is generated in response to a comparison of a difference value to a percentage of another difference value.

La présente invention concerne une procédé permettant de détecter une occlusion dans un tube pour perfusion (16) souple par mesure d'échantillons indiquant respectivement la pression à différents moments. Les valeurs différentielles pour les échantillons sont créées. Les valeurs différentielles sont comparées à des pourcentages d'autres valeurs différentielles. Le cas échéant, un signal d'occlusion est généré en réponse à une comparaison de valeur différentielle avec un pourcentage d'une autre valeur différentielle.
