Abstract

EL APARATO PARA AEROSOLIZAR UN POLVO CONTENIDO EN UN RECEPTACULO QUE TIENE UNA SUPERFICIE DE ACCESO PERFORABLE CONSTA DE: A) UNA ENVOLTURA BASE; B) UN SUJETADOR DENTRO DE LA ENVOLTURA BASE PARA SOSTENER EL RECEPTACULO EN UN SITIO DE FLUIDIFICACION; C) UN TUBO DE ALIMENTACION DENTRO DE LA ENVOLTURA BASE QUE TIENE UN EXTREMO DE ENTRADA EN UN SITIO DE FLUIDIFICACION; Y D) MEDIOS PARA HACER FLUIR UNA CORRIENTE DE GAS A ALTA PRESION PASANDO POR UNA PORCION DEL TUBO DE ALIMENTACION, EN EL CUAL EL POLVO SE FLUIDIFICA PARTIENDO DE UN RECEPTACULO EN EL SUJETADOR Y EXTRAIDO AXIALMENTE A TRAVES DEL TUBO Y DISPERSADO EN LA CORRIENTE DE AIRE A ALTA PRESION PARA FORMAR UN AEROSOL. SE UTILIZA EN LA ADMINISTRACION PULMONAR DE DROGAS DISPERSANDO MEDICAMENTOS EN POLVO SECO PARA LA INHALACION DEL PACIENTETHE APPARATUS FOR AEROSOLIZING A DUST CONTAINED IN A RECEPTACLE THAT HAS A PERFORABLE ACCESS SURFACE CONSISTS OF: A) A BASE WRAP; B) A FASTENER WITHIN THE BASE WRAP TO SUPPORT THE RECEPTACLE IN A FLUIDIFICATION SITE; C) A FEED PIPE WITHIN THE BASE ENCLOSURE THAT HAS AN END OF ENTRY INTO A FLUIDIFICATION SITE; AND D) MEANS TO FLOW A HIGH PRESSURE GAS STREAM PASSING THROUGH A PORTION OF THE FEEDING TUBE, IN WHICH THE DUST IS FLUIDIFIED FROM A RECEPTACLE IN THE HOLDER AND AXIALALLY EXTRACTED THROUGH THE TUBE AND DISPERSED IN THE AIR AT HIGH PRESSURE TO FORM A SPRAY. IT IS USED IN THE PULMONARY ADMINISTRATION OF DRUGS DISPERSING DRY POWDER MEDICATIONS FOR THE PATIENT INHALATION
