Patent number: 7306460Abstract: A dental vacuum system for use in dental operatories wherein a dental aspirator tip and in the dental operatory is in fluid communication with a vacuum means for providing suction to the system, there being interposed between the aspirator tip and the vacuum means a separation chamber for the separation of effluent, and solids, including amalgam and other particulate matter from the air stream, the separation chamber being in communication with a collection chamber for the separation collection of solids, amalgam and other particulate matter, from the effluent which is discharged, the collection chamber being removably replaceable from the system for the recycling of the contents.Type: GrantFiled: July 22, 2004Date of Patent: December 11, 2007Inventors: Henry Hubner, Frederick R. Fischer

Patent number: 7214059Abstract: 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.Type: GrantFiled: March 5, 2002Date of Patent: May 8, 2007Inventor: Atsushi Takahashi

Patent number: 7182599Abstract: An inline filter assembly to be used in conjunction with surgical or other procedures, near the patient or chairside in dental operations, that is capable of removing, by filtration, particulate matter from waste-water. The filter assembly is configured to permit easy and rapid changing of filters. The filter assembly also contains a series of stopcocks to permit easy and quick changing of filters while maintaining suction to the patient.Type: GrantFiled: June 15, 2005Date of Patent: February 27, 2007Assignee: The United States of America as represented by the Secretary of the NavyInventors: Mark E. Stone, Jeffrey M. Gullett, John C. Kuehne

Patent number: 7063793Abstract: The present invention is directed to processes for removing a contaminant from dental effluents and includes transporting a three-phase effluent through a suction line into a particle collection vessel, introducing a suction line cleaning solution which includes a reagent into the suction line, and introducing the three phase effluent and the line cleaning solution into the collection vessel, wherein the effluent separates into solid. liquid, and gas phases in the collection vessel and the reagent includes a flocculant and/or a precipitant. and removing the gaseous and liquid phases from the collection vessel. The contaminant includes mercury. lead. and arsenic.Type: GrantFiled: August 25, 2004Date of Patent: June 20, 2006Assignee: Ada Technologies, Inc.Inventors: Jason Albiston, Craig S. Turchi, Allan Carlson

Patent number: 6946069Abstract: 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.Type: GrantFiled: September 9, 2003Date of Patent: September 20, 2005Assignee: SolmeteX, Inc.Inventor: Richard H. Chilibeck

Patent number: 6923646Abstract: 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.Type: GrantFiled: April 17, 2002Date of Patent: August 2, 2005Assignee: Air Techniques, Inc.Inventors: Henry Hubner, Elliot R. Gemunder, Selwyn Foster, Jr.

Patent number: RE46086Abstract: 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.Type: GrantFiled: January 16, 2014Date of Patent: August 2, 2016Assignee: DENTAL EQUIPMENT, LLCInventors: Tom Benfield, Joseph James Bria, III, John Paul Helgesen, Austin Unsworth
