Patent number: 7367803Abstract: This invention creates a convenient low cost water pressure driven multi user oral cleansing device, the DentalJet with exchangeable color coded nozzle/handle which is easy to use, needs no electricity. The invention uses a faucet attachable rotating diverter, a flexible longer food grade PVC tube and interchangeable color coded jet nozzle/handle. The diverter also functions as a fine water volume/pressure control with a preset temperature and filter. Water pressure bulges up the flexible rubber tube clamped to the end of the adapter and to the PVC tubing. Inside the handle the water pressure created friction keeps the hose adapter in solid coupling while the pressure is on. The rubber tube oscillates, as pulsating water exist at the nozzle. When the water pressure is removed, color coded nozzle/handle is exchangeable.Type: GrantFiled: April 5, 2004Date of Patent: May 6, 2008Inventor: Zoltan Egeresi

Patent number: 7080980Abstract: A dental hygiene system provided with interchangeable dental heads permits power-enhanced brushing and concurrent fluid irrigation to optimize a user's personal dental hygiene efforts. The system has a handle assembly with an irrigation nozzle in close proximity to displaceable bristles driven by a battery-operated handle motor. Pumping of irrigation fluid such as an antiseptic solution into the oral cavity is also motor driven. A telescoping chamber with irrigation fluid fits on the piston-like base end of the handle and is refilled by docking the handle assembly on a complementary docking station that includes a detachable fluid reservoir, microswitch controls and a base fluid pump. Docking of the handle assembly triggers the microswitches and opens a check valve in the bottom of the handle chamber, which activates the flow of fluid from the reservoir into the chamber. An optional fiberoptic subassembly illuminates the oral cavity.Type: GrantFiled: July 6, 2004Date of Patent: July 25, 2006Inventor: Michael Klupt

Patent number: 6766549Abstract: A toothbrush system using a combination of mechanical force and fluid dynamics to increase the efficiency of plaque removal from the teeth and gums. The toothbrush includes a head unit with an irrigator nozzle and a hydraulically actuated and continuously variable bristle platform which negotiates the complex surface geometry found in the mouth of a user. The irrigation nozzle is powered by the pulsing of an anti-microbial irrigant which gives the toothbrush head unit the distinguishing ability of being able to “feel” the contour of the teeth and to “find” the spaces between them. Once the sensing irrigator nozzle finds the spaces between the teeth, it extends into the area, and releases the anti-microbial liquid directly into the space. The configured bristle tufts of the head unit automatically adjust their position for cleaning under the gum line, between the teeth, as well as flat surfaces.Type: GrantFiled: April 17, 2002Date of Patent: July 27, 2004Inventor: Michael F. Klupt

Patent number: 6740053Abstract: A water flossing apparatus for successful use with domestic water pressure service with its inherently higher flow rates. The apparatus contains a body 2 that is adapted to either shower, sink faucet or hose bibb connection, allowing for concurrent device and shower, device and sink or device and hose usage. The body contains a valve mechanism with lever 8 for regulating flow through the device and jet tip 14 whose bent end 15 is acutely angled beyond 90 degrees to the longitudinal axis of the hand piece to direct water out of the user's mouth. Directing water out of the user's mouth rather that towards the back of the user's throat, as occurs with the obtusely angled, slightly bend jet tips of the prior art, prevents the throat from being inundated with water and a gagging potential is thus mitigated.Type: GrantFiled: March 20, 2002Date of Patent: May 25, 2004Assignee: Millenium Media Marketing, LLCInventor: Gary H. Kaplowitz

Patent number: 5934902Abstract: The oral cleansing device assembly is an oral hygiene tool which relies upon weak strength and small sized magnets in order to effect a change in the resonance and/or polarity of the water molecules such that the water is effective for cleaning debris, scale, and plaque from the teeth, gums, tongue, and oral cavity in general. The oral cleansing device assembly has a non-metallic housing which contains the magnets and tubing through which water passes when the device is in operation; the housing also doubles as a handle. The oral cleansing device assembly has jet-tips for discharging the water into an oral cavity; the jet-tips are attachable to a quick-connector within the housing of the oral cleansing device assembly. The oral cleansing device assembly is ideal and safe to use for any adult or child who seeks to avoid exposure to electromagnetic fields and who wishes to avoid use of high water pressure in their mouth care routine.Type: GrantFiled: April 16, 1998Date of Patent: August 10, 1999Inventor: Mansur Abahusayn

Patent number: 5928505Abstract: The present invention is directed to a water purification and dispensing apparatus which receives power through induction to eliminate the presence of exposed electrical contacts terminals. The water dispenser includes a motor driven pump, a water storage area, a rechargeable battery and a nozzle, such that water is pumped from the water storage area out through the nozzle. Two electrodes are provided in either the water storage area or a separate tank for purifying water placed therein. When the dispenser and/or purifying tank is mounted on a base, inductors in the base, the dispenser, and the tank connect via mutual inductance such that power supplied by the base is received by the dispenser and tank. Since power transfers magnetically, there are no exposed contact points which could corrode and/or short if water is accidentally spilled thereon.Type: GrantFiled: November 26, 1997Date of Patent: July 27, 1999Assignee: Matsushita Electric Works, Ltd.Inventors: Satoru Inakagata, Takahiro Heiuchi

Patent number: 5860942Abstract: A handpiece has a cavitation orifice therein. A pump supplies water from a reservoir through the cavitation orifice to produce cavitation in the water downstream from the orifice. This cavitation produces OH radicals and ions in the water flow. The water flow is directed onto dental surfaces. The OH radicals and ions have been proven effective against bacterium.Type: GrantFiled: March 12, 1997Date of Patent: January 19, 1999Inventor: Dale W. Cox

Patent number: 5829976Abstract: A dental brush having a flexible fibrous tip with internal cannula to allow medicament, such as tetracycline, chlorhexidine or stannous fluoride, or combinations thereof to flow through the fibrous tip. The flexible fibrous tip includes a nonwoven tufted surface that completely covers the tip to remove plaque. The applicator tip fits between the teeth and the gum line and delivers both physical and chemical treatment to interproximal periodontal pockets. The medicament solution is stored in a disposable sealed and sterile cartridge and is held in the base of the device. A pump built into the base provides pressure to push the medicament through the cannula to the fibrous brush tip to provide site-specific dosage-controlled treatment. The brush tip is disposable and provides effective interproximal subgingival debridement and site-specific application of medication to infected areas.Type: GrantFiled: December 19, 1996Date of Patent: November 3, 1998Inventor: Warren F. Green

Patent number: 5820373Abstract: A periodontal pocket cleaning device is provided which has a very excellent effect for the prevention of periodontal diseases, which is least liable to cause injury to the periodontal pocket, which can be used at any place without limiting the place of its use, which is able to obtain a stabilized atomized jet without being influenced by the height position of the handy probe, and which is available at a low cost. The periodontal cleaning device includes a handy probe provided with an air-jet ejection mechanism, an air pump for producing compressed air, and an air-feeding tube for feeding the compressed air from the air pump to the handy probe. The handy probe is provided with a liquid storage tank for storing liquid agent such as water or liquid chemicals therein. The jet-out pressure of the compressed air to be ejected from the nozzle of the handy probe is set in a range of from 0.05 to 0.08 kg/cm.sup.2. The jet-out quanity of the compressed air is set in a range of from 2 to 30 l/min.Type: GrantFiled: December 13, 1996Date of Patent: October 13, 1998Assignee: Koichi OkanoInventors: Koichi Okano, Tsuguo Matsui, Michihisa Sugimoto, Masaharu Kita, Takashi Morita, Tomoko Asai
