Abstract:
1. An at-home integrated cleaning and disinfection system for dental hardware, for consumer use, comprising: a portable base unit sized for at-home use by a consumer, the base unit comprising a holding frame and an ultraviolet lamp; a cleaning chamber within which dental hardware and a cleaning solution comprising hydrogen peroxide are receivable, the cleaning chamber fitting within the holding frame in a manner such that contents of the cleaning chamber are exposed to light emitted by the ultraviolet lamp; a vibration mechanism positioned to cause the cleaning chamber and the contents therein to vibrate while the cleaning chamber is fitted within the holding frame; and a cleaning solution comprising hydrogen peroxide received within the cleaning chamber; wherein a biocidal action is caused by dissociation of hydrogen peroxide molecules into free hydroxyl radicals upon absorption of ultraviolet light by the hydrogen peroxide molecules, the free hydroxyl radicals in turn chemically attacking and killing bacterial or viral cells, wherein the portable base unit further comprises a source of DC power electrically connected to the ultraviolet lamp; wherein the vibration mechanism is electrically connected to the source of DC power; and wherein the at-home integrated cleaning and disinfection system further comprises a docking station housing AC electronics and AC-DC rectification electronics, the docking station being configured to mate with the base unit and to power the base unit while mated with the base unit, the base unit being configured to activate the ultraviolet lamp and the vibration mechanism by DC power while the base unit is separated from the docking station.
