Abstract
SE DESCRIBE UN REGULADOR DE SUCCION INTERMITENTE QUE FUNCIONA A PARTIR DE UN SISTEMA DE VACIO Y SE EMPLEA PARA PRODUCIR SEÑALES NEUMATICAS DE SALIDA A UN DISPOSITIVO DE IMPULSO POSITIVO PARA LA RECUPERACION DE FLUIDOS EXTRAIDOS DE UN PACIENTE DURANTE DRENAJE A FIN DE LIMPIAR LOS CONDUCTOS. EL REGULADOR DE SUCCION O UNIDAD DE CONTROL PRODUCE DOS (2) SEÑALES DE SALIDA SINCRONIZADAS A PARTIR DE UNA (1) ENTRADA DE VACIO INTERMITENTE HACIA PRESION ATMOSFERICA. UNA SEÑAL DE SALIDA CAMBIA CONSTANTEMENTE DE SEÑAL DE VACIO REGULADO A SEÑAL DE PRESION ATMOSFERICA, MIENTRAS QUE LA OTRA SEÑAL DE SALIDA CAMBIA DE SEÑAL DE VACIO NO REGULADA A SEÑAL DE PRESION ATMOSFERICA. LAS SEÑALES ESTAN SINCRONIZADAS DE FORMA QUE AMBAS INICIALMENTE PROPORCIONAN SEÑALES DE VACIO SIMULTANEAMENTE, EXISTIENDO SIN EMBARGO UN RETARDO TEMPORAL PREDETERMINADO ENTRE EL TIEMPO EN QUE LA SEÑAL DE SALIDA DE VACIO REGULADO CAMBIA DE VACIO A ATMOSFERICA Y LA SEÑAL DE SALIDA DE VACIO NO REGULADO CAMBIA DE VACIO A ATMOSFERICA. AMBASSEÑALES DE SALIDA, SIN EMBARGO, RETORNAN A SUS SEÑALES DE VACIO SIMULTANEAMENTE TRAS UN CICLO TEMPORAL PREDETERMINADO.
