Abstract

UN DISPOSITIVO PARA INYECCIONES SIN AGUJA PROVISTO DE UN ALOJAMIENTO QUE CONTIENE UNA VALVULA PILOTO CONECTABLE A UNA FUENTE DE GAS COMPRIMIDO. UNA VALVULA AMPLIFICADORA DE POTENCIA DE DOBLE ETAPA INCLUYE UNA VALVULA PRINCIPAL CONECTADA OPERATIVAMENTE A LA VALVULA PILOTO. ESTA VALVULA PILOTO Y LA PRINCIPAL FORMAN OTRA VALVULA DE DOBLE ETAPA CON LA VALVULA PILOTO ACTIVABLE PARA ABRIR LA PRINCIPAL UTILIZANDO GAS A PRESION. EL GAS COMPRIMIDO EN UN RECIPIENTE FLOTA A TRAVES DE LA VALVULA PRINCIPAL ABIERTA PARA ACCIONAR UN EMBOLO EN UNA AMPOLLA PARA INYECTAR UNA SOLUCION INYECTABLE A TRAVES DE LA PIEL DEL PACIENTE. SE PROPORCIONAN SINCRONIZADORES PARA RESISTIR LAS ACTUACIONES INESPERADAS DEL DISPOSITIVO Y UN INDICADOR QUE INDICA SI HAY SUFICIENTE PRESION DE GAS EN EL DISPOSITIVO PARA OTRA INYECCION.
