Self contained aerosol dual delivery system (scadds)

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. The oral reservoir may be coupled with a second reservoir for finely divided solids or divided by a filter such that finely divided solids can interact with the oral solution to further enhance flavor. 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.
