Abstract

Se describe un método para controlar la operación de un impulsor de un dispositivo de infusión ambulatorio (2), en el que el impulsor del dispositivo de infusión ambulatorio (2) incluye un mando de husillo (2), con un motor de velocidad gradual (21), y un codificador rotativo (23) en acoplamiento operativo con la pieza impulsora; el método incluye ejecutar en forma reiterada una secuencia de controles del impulsor, donde la secuencia de controles del impulsor comprende lo siguiente: a) accionar el motor de velocidad gradual (21) para que ejecute un número de pasos solicitados en la secuencia actual de controles del impulsor; b) recibir la posición de la pieza impulsora, donde la posición de la pieza impulsora es indicativa de una posición real de la pieza impulsora luego del accionamiento; c) calcular, a partir de la posición de la pieza impulsora y del número de pasos solicitados, un número de pasos frustrados como un desvío entre el número de pasos solicitados y el número de pasos ejecutados en la secuencia actual de controles del impulsor; d) determinar, basándose en una evaluación estadística de la distribución en el tiempo del número de pasos frustrados, contra un historial de secuencias de control del impulsor, si el impulsor (2) está bloqueado. El método incluye, además, generar una señal de alarma de bloqueo si se determina que el impulsor está bloqueado.
