摘要:
A device for dispensing a dental paste comprises a first nozzle for delivering the paste and a second nozzle for delivering a gas stream. The device is adapted for simultaneously delivering the gas stream and the paste toward a working area. The invention helps minimizing efforts in a dental treatment and maximizing the quality of that dental treatment.

A teeth whitening device (10) includes a generator (30) configured to generate a teeth whitening fluid that whitens teeth and humidified gas, a mouthpiece (100) configured to supply the teeth whitening fluid and the humidified gas, and a coupling part (20) that couples the generator (30) and the mouthpiece (100) with each other. The mouthpiece (100) includes a first supply port (103) through which the teeth whitening fluid is supplied, and a second supply port (104) through which the humidified gas is supplied, the second supply port (104) being separated from the first supply port (103). The mouthpiece (100) further includes a first supply passage (101) configured to guide the teeth whitening fluid to the first supply port (103), and a second supply passage (102) configured to guide the humidified gas to the second supply port (104), the second supply passage (102) being separated from the first supply passage (101).

The invention is directed to providing, at the exit from the nozzle of an irrigator, an intermittent gas-liquid jet for enabling effective cleaning, while being easy to use. A bulb (1) has an aerator introduced therein which is in the form of a tubular element (7) with open tips (71, 72) and a perforation region (73) in the side wall of the element (7), said region being comprised of at least one hole. The end of the tubular element (7) on the open-ended side is freely disposed in the cavity of the bulb (1), and the tip (71) is disposed with clearance from the base of the bulb.

Oral cleansing device (10) includes tank (40) for storing a cleaning fluid, cleansing unit (100) having exhaust port (810) that discharges the cleaning fluid, cleansing duct (60) for communicating between tank (40) and exhaust port (810), pump (30) for sucking the cleaning fluid stored in tank (40) with a negative pressure and discharging the sucked cleaning fluid to exhaust port (810), and suction duct (70) for supplying air to cleansing duct (60). Suction duct (70) is connected to downstream cleansing duct (62) that is a part of duct (60) and is located on a downstream side from pump (30) such that air can be sucked into cleansing duct (60) with a negative pressure produced by pump (30). This structure allows oral cleansing device (10) to give a pleasant stimulus to gums.
