Abstract

Un sistema de medición de duración de tiempo de inyección de fármaco en tiempo real incluye un transductor de sonido, un circuito de conformación de forma de onda acoplado de manera operativa con el mismo, un circuito de sujeción de impulsos acoplado de manera operativa con el circuito de conformación de forma de onda, y un temporizador acoplado de manera operativa con el circuito de sujeción de impulsos. El transductor de sonido detecta un primer sonido asociado con el inicio de la administración del fármaco y un segundo sonido asociado con la finalización de la administración del fármaco, y convierte además los sonidos detectados primero y segundo en una primera forma de onda electrónica y una segunda forma de onda electrónica, respectivamente. El circuito de conformación de forma de onda convierte las formas de onda primera y segunda en un primer impulso y un segundo impulso, respectivamente. El circuito de sujeción de impulsos se activa tras recibir el primer impulso y generar un impulso regenerado. El temporizador se inicia tras recibir el impulso regenerado y se detiene tras recibir un impulso regenerado posterior a través del circuito de sujeción de impulsos.
