Abstract

Dispositivo de infusión de medicamentos fluidos que tiene un reservorio presurizado de medicamento, un catéter de administración del fármaco al paciente y una válvula dispuesta entre ambos, donde la válvula tiene una cámara (19) intermedia que, en función de la posición de un elemento (9) obturador, se comunica alternativamente bien con el reservorio (1) para ser llenada de medicamento, o bien con el catéter (8) para la administración del mismo. Un émbolo (11) dosificador que tiene una posición extendida donde su extremo este al menos parcialmente introducido en la cámara (19) intermedia se encarga de impulsar el medicamento fluido hacia el catéter. Se mejora la precisión de los dispositivos actuales, ya que puede controlarse con gran precisión el volumen de medicamento administrado al paciente con una gran precisión. El diseño de la válvula proporciona una mayor seguridad.
