Abstract

Un dispositivo dispensador impulsado por fluido, en el cual un pistón impulsado por el fluido descargado desde un motor, mueve el émbolo para desplazar los contenidos de la jeringa. El área de sección transversal del émbolo es mayor que el área del pistón expuesta al fluido impulsor, De manera que un volumen dado de fluido descargado desde la bomba desplazará un volumen mayor de agente benéfico. desde la jeringa. También se pueden proveer medios para dirigir el fluido descargado desde el motor alejándolo del pistón, para permitir una operación de conexión/desconexión de la jeringa.
