Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
247 words
A novel toothbrush comprising: a row of gum-massaging plastic bars on each one of two sides of a brush bristle section seat; a suction and fluid jet pipe at the front end of said bristle section seat, an enclosed fluid channel at the center of said toothbrush handle body, the said suction and jet pipe being connected to said fluid channel, said channel leading to the distal end of said toothbrush handle body; a squeeze bulb connected to the said distal end, and a partially closed channel on the back of said handle body for enclosing a tooth-picking flexible member controlled by a slidable push button; said partially closed channel leading to an aperture at one side of the said suction and jet pipe; the operation of said toothbrush being characterized by massaging the gums with the two rows of plastic bars, by removing the food residues caught in the gaps between teeth with the suction fluid and jet forces generated by pressing the squeeze bulb applied to the said gaps while the nozzle of said suction and fluid jet pipe is contacting the said gaps, by making the tooth-brushing action more comfortable without hurting or bloodying the gums with the said bars, and by picking out the food residues tightly caught at the gaps between teeth with a pointed end of said tooth-picking member which is extended out by means of sliding the push button, in addition to achieving normal tooth-brushing purposes with the toothbrush bristles.
