And Suction Pump Or Material Separator Patents (Class 433/92)
  • Patent number: 11246692
    Abstract: A dental waste containment system having a treatment stage to reduce the contaminant levels of the stored fluid. The treatment stage may include a settling canister disposed before the fluid storage reservoir to remove and contain at least some solid contaminants from the fluid waste before the fluid waste is moved into storage. The system may include a bypass subcircuit to allow fluid waste to selectively bypass the treatment stage. The present invention also provides a method of collecting, containing and transporting dental waste that includes separate containment of solid and fluid dental waste. The method includes at least partial separation and containment of solid contaminants in the treatment stage before the fluid dental waste is moved into separate storage. The accumulated fluid dental waste and accumulated solid waste may be separately collected from the system and separately transported to a remote facility for treatment, reclamation and/or disposal.

  • Patent number: 9901044
    Abstract: A method is provided for controlling the fluid level in an ebb and flow watering system control bucket that is in fluid communication with at least one fluid holding apparatus such as a plant container with connecting water lines, causing hydraulic delays in changes in the fluid level in the control bucket when fluid is pumped to or from the control bucket, typically from a fluid reservoir. The method involves pumping fluid to or from the control bucket to achieve a target fluid level in the control bucket; upon the fluid reaching the target fluid level, starting a timer for a short period of time to allow for the hydraulic delays, and continuing to pump fluid while the timer runs; restarting the timer and continuing to pump fluid if the fluid level in the control bucket recedes from the target fluid level; and discontinuing pumping if the timer runs for the full period of time.

  • Patent number: 6946069
    Abstract: An apparatus for separating solid particles from the suction effluent of, for example, a dental office, preferably driven by a dental office vacuum pump, includes a surge tank for accommodating effluent overfill connected to a sedimentary deposit tank for sedimentation of effluent particles. A bypass conduit is connected to the surge tank inlet which is equipped with a vacuum break valve for allowing air into the system when the suction openings are closed. The sedimentary deposit tank has a series of baffle chambers through which effluent flows in sequence, and in each of which chambers sediment is deposited for later removal. The surge tank preferably has a liquid level sensor and warning device. Modular filters or adsorbants may be installed in the sedimentary deposit tank, or a modular auxiliary filter may be connected downstream of the tank. Chemical injection may be used to improve sedimentation.

  • Patent number: 6923646
    Abstract: There is disclosed a process and apparatus for withdrawing an exhaust stream including gas, liquids and solids from the dental operatory connected to the suction side of a vacuum pump wherein solids and liquids are sequentially removed such that compressed gas from the vacuum pump is passed through a heat exchanger for cooling, thus permitting the use of lightweight, less expensive conduit piping for a vent exhaust conduit.

  • Patent number: 6790346
    Abstract: Cyclone separator with flow rate regulation for separating solid particles from a fluid, comprises a recipient having a fluid inlet and an upper outlet for clarified fluid. The separator also comprises a recycling conduit which places an outlet conduit in communication with the inlet, a three-way valve to an inlet of which the outlet conduit is connected, and to outlets of which the recycling conduit and the outlet are connected. The three-way valve has an obturator which can block the connection between the outlet conduit and the recycling conduit, a one-way valve which has an obturator and is located at the outlet downstream of the three-way valve. The one-way valve is normally closed and can connect the outlet conduit with the outlet. The three-way valve and the one-way valve are brought into action when the fluid pressure in outlet from the separator reaches first and second predetermined values.

  • Publication number: 20040115590
    Abstract: A bone piece collecting device, wherein, when bone pieces are mixing agitated with the other substances while preventing the loss of the cut bone pieces collected on a filter and contamination thereof by saliva by a self-bone transplanting method, a filter part is installed in a filter holder with impermeability to eliminate the operation for transferring the bone pieces to the other container, a collected bone container for filling bones is prevented from being fallen down by stably fixing the container to a cuff for operation or an operation table with an adhesive tape or a magic tape installed at the bottom part of the filter holder so as to facilitate the removal of the collected bones, and a gradient is marked on the transparent or semi-transparent material of the filter holder so that the amount of collected bones can be weighed easily.

    Abstract: The invention pertains generally to dental units (e.g., a high-speed dental handpiece (11), an ultrasonic scaler(13) and an air/water syringe(12)) connected to a water supply that provides coolant and rinse water to the dental units. More particularly the invention pertains to a dental unit using water that is continuously treated with a water treatment agent, such as microbiocidal silver ions. The treated dental unit water is supplied to the dental units via dental unit waterlines (6, 7, 8, 9, 10).

  • Publication number: 20030186189
    Abstract: A waste liquid tank B is connected to a cleaning head 60 through a waste tube 25. Squeezing means 61 is provided in a waste flow passage of from an end 60a of the cleaning head 60 to a suction port b of the waste liquid tank B to squeeze the waste flow passage. A pump A is driven with a cleaning head 60 introduced in the oral cavity to suck the residual matter in the oral cavity and to drain it into the waste liquid tank B in order to clean the oral cavity. When the residual matter cannot be sucked with a normal suction force, the waste flow passage is squeezed by the squeezing means 61 to increase the negative pressure in the waste tube 25. Thereafter, the squeeze is released to suck the residual matter at a breath with the increased negative pressure.

  • Patent number: RE46086
    Abstract: An instrumentation delivery unit which supports hand-held dental instruments. In one example first and second housing members form a sealed chamber. When the members are separated, access is permitted to the interior of the chamber, e.g., for maintenance purposes. A first portal suitable for connection to a vacuum line provides a partial vacuum in the chamber, and second portals provide connection via second vacuum lines between the chamber and dental devices to operate the devices. The housing includes hand piece holders each of an initial diametric size for receiving hand pieces up to a maximum diametric dimension, with one of the hand piece holders formed along two adjoining ones of the housing members. The adjoining housing members secure inserts between one another to provide a second diametric size smaller than the initial diametric size to thereby selectably accommodate hand pieces having a smaller diametric dimensions.
