Patent ID: 7367803

Claim:
A multi-user oral cleansing device comprising: a diverter for connection to a faucet, said diverter having a valve for diverting water from the faucet; an elongated connecting hose having opposite first and second ends, said first end connected to the diverter for conveying water from the valve; a dental jet hand piece being connected to the second end of the elongated connecting hose and having a nozzle for directing fluid to a patient's oral cavity, said jet hand piece having an adapter for pulsating the flow of water through the jet hand piece, said adapter being comprised of an elongated rigid tubular member having barbed first and second ends and a first fluid passage extending longitudinally there through, said adapter further including a second fluid passage extending diagonally through the tubular member wall and in communication with the first fluid passage, said first barbed end being connected to the second end of the elongated connecting hose, said adapter further comprising a rubber hose that extends over the second barbed end of the tubular member and covers the second diagonal fluid passage; wherein when water flows through the jet handpiece water is conveyed through the adapter first passage and through the second passage where the water pressure repeatedly bulges the rubber hose around the tubular member second barbed end until the water is released out the end of the rubber hose and the bulging hose collapses, the repeated bulging and collapsing of the rubber hose causing the water directed out of the nozzle to pulsate.
