Toothbrush with fluid injection and removal by vacuum

摘要

A toothbrush for supplying fluid to the bristles (7) and vacuum means to remove the used fluid from the mouth. A fluid supply line (5) passes through the toothbrush handle (2) and exits in the center of the bristles (7). The bristles (7) are surrounded at their base by a region (8), which communicates with the vacuum chamber (3) in the handle (2). The used fluids are extracted through region (8), to disposal via Vacuum chamber (3) and connection (4). A tube like member (9) with vent holes (10) is placed adjacent the bristles (7). The tube like member (9) is sufficiently long that during inadvertent mouth closure it allows air ingress, through the vents (10), into the mouth to prevent undesirable vacuum in the patient's mouth.
