Title: Innovations by David R. Busick
Introduction
David R. Busick is an accomplished inventor based in Lewis Center, Ohio. He holds a total of six patents, showcasing his significant contributions to the field of pulmonary therapeutics. His work primarily focuses on improving aerosol delivery systems, which are crucial for effective medication administration.
Latest Patents
One of his latest patents is for a nozzle designed for handheld pulmonary aerosol delivery devices. This improved Electrohydrodynamic (EHD) nozzle enhances the consistent and efficient dispensing of therapeutic liquids. It achieves this by reducing or eliminating wetting through the shielding of discharge electrodes. Some versions of the nozzle further enhance neutralization of the aerosol by presenting a corona wind of ions that annularly surrounds the aerosol. The incorporation of improved liquid distribution with consistent pressure drops to each EHD nozzle tip allows for horizontal dispensing. Additionally, the use of dielectric nozzle tips with low surface energy helps avoid wicking between dispenses and reduces the achievable particle size during dispensing. Notably, these EHD nozzles can achieve a high dose rate of microliters per minute while maintaining low wetting and small particle sizes ranging from 1.0 to 5 microns. Furthermore, these attributes are integrated into a conveniently small, handheld device.
Another significant patent by Busick is a drug containment system. This container closure device facilitates the withdrawal of liquid from a collapsible sealed packet. The device features a needle guide and a septum retainer, ensuring proper alignment of the needle for effective liquid withdrawal. The needle guide is fixable to the outer face of the packet, while the septum retainer aligns with it on the inner face.
