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.A fluid powered dispensing device, in which a piston powered by fluid discharged from an engine, moves the plunger to displace the contents of the syringe. The cross sectional area of the plunger is greater than the area of the piston exposed to the driving fluid, so that a given volume of fluid discharged from the pump will displace a larger volume of beneficial agent. from the syringe. Means may also be provided to direct the fluid discharged from the motor away from the piston, to allow a syringe on / off operation.
