ABSTRACT:
Self Contained Aerosol Dual Delivery System (SCADDS) is a pocket-sized inhaler for delivering inhaled therapeutic or recreational aerosols simultaneously and separately via oral and nasal routes. A handle assembly has a removable mouthpiece, cartridge penetration needles, puncture needle protective cover, a shuttle, a cam, valves and conduits from the penetration needles to the individual nozzles for oral and nasal inhalation. A cartridge contains separate reservoirs of solutions for oral and nasal inhalation. The reservoirs, impermeable bags with fluid and dissolved gas in solution, are punctured when the cartridge is attached to the handle assembly. Inhalation slides the shuttle toward the mouthpiece and opens the valves to release solution. The oral aerosol is inhaled into the lungs while the nasal aerosol provides a pleasant aroma. To enhance oral inhalation solution properties the oral inhalation reservoir may contain finely divided solids in a semi-permeable membranous bag, attached to a second reservoir, or be divided by a filter such that these solids do not occlude nozzles or penetration needles Degassed water may be used to enhance organic compound solubility in solutions. Alternative reservoir bag systems are twin spring driven or gas driven cylinders to provide proper pressure to aerosolize nasal and oral fluids. Hydraulic intensification, piezoelectric pumping devices, and electromechanically driven pressure pumps are alternative pressurization systems.
