Title (EN) DENTIFRICE-MEDICATION DISPENSING TOOTHBRUSH
(FR) BROSSE A DENTS DISTRIBUANT DU DENTIFRICE/DES MEDICAMENTS
Abstract:
(EN) A vibrating toothbrush which includes a brushhead (18) mounted for vibrating movement, a reservoir (30) for containing dentifrice which is located in the handle (14) of the toothbrush, and fluid connecting means (32) connecting the reservoir (30) to the brushhead (18). The brushhead (18) includes either hollow bristles (80) or nozzles (87) in the brushhead (18) to permit egress of the dentifrice from the brushhead (18) in the area of the bristles. The brushhead (18) is driven so as to provide a scrubbing action for the teeth and to provide acoustical energy for acoustical cleansing as well. The action of the brushhead (18) and the load thereon will result in dentifrice being released out of the brushhead (18) or bristles (80) as needed, supporting cavitation and streaming for the acoustical energy, as well as providing the cleansing/therapeutic effect of the dentifrice.
(FR) Brosse à dents vibrante comprenant une tête de brosse (18) montée pour avoir un mouvement vibrant, un réservoir (30) destiné à contenir du dentifrice et situé dans le manche (14) de la brosse à dents, ainsi qu'un moyen de raccordement fluide (32) reliant le réservoir (30) à la tête de la brosse (18). La tête de la brosse (18) comprend soit des soies creuses (80) soit des ajutages (87) situés dans ladite tête de brosse (18) afin de permettre la sortie de dentifrice de ladite tête de brosse (18) dans la zone des soies. La tête de la brosse (18) est commandée de manière à exercer une action de frottement sur les dents et de manière à produire une énergie acoustique assurant également un nettoyage acoustique. L'action de la tête de la brosse (18) ainsi que la charge exercée sur celle-ci ont pour effet de libérer du dentifrice de la tête de la brosse (18) ou des soies (80) selon l'option choisie, d'entretenir la cavitation et l'écoulement de l'énergie acoustique, ainsi que de favoriser l'effet de nettoyage/thérapeutique du dentifrice.
