| 101 | Thin-film splash guard for a dental cuspidor | US12246331 | 2008-10-06 | US08393022B2 | 2013-03-12 | Damian D. Dachowski |
| A thin-film splash guard for use with dental cuspidors is described. The splash guard includes a thin-film sheet, a pair of slots, and an adhesive. The thin-film sheet is composed of a flexible, flaccid material with front and back surfaces which is sufficiently stiff when conformed to the shape of a dental cuspidor so as to extend above the side wall of the cuspidor. The slots are disposed from one edge of and along the thin-film sheet so as to generally define a center region and a pair of side regions. The adhesive is disposed along the front surface within each side region and or along the back surface within the center region. The thin-film splash guard is readily conformable to the shape and size of a cuspidor, easily attachable to the cuspidor in a removable fashion, and disposable. | ||||||
| 102 | Cuspidor | US11321 | 1993-01-29 | US5367717A | 1994-11-29 | William F. Fisher |
| A cuspidor having a substantially rounded basin with a bottom, a substantially upright surrounding sidewall and a fluid inlet spaced above the bottom adjacent one end of the basin for directing flushing fluid into the basin. The juncture between the bottom and sidewall of the basin is formed in a concave curve which varies from a first radius at the end of the basin adjacent the fluid inlet to a smaller second radius adjacent the opposite end of the basin. The bottom also has a substantially flat section adjacent a portion of the juncture section which merges with an intermediate section for directing flushing fluids to a drain hole. The configuration of the basin provides efficient flushing and minimizes the possibility of flushing fluid splashing over the sidewall. | ||||||
| 103 | Spitting device for dental purposes | US508885 | 1983-06-29 | US4470163A | 1984-09-11 | Hans M. Kratochwilla |
| A cuspidor or spitting device for dental purposes comprising a bowl formed by a lateral curved wall and a conical bottom surface with the upper edge of the lateral curved wall merging with an inclined surface portion of the upper surface of the housing and the bottom wall having a discharge opening leading to a discharge channel. The lateral wall is preferably a cylinder or a tapering surface substantially forming a cylinder whose axis of rotation is arranged to incline from the user's side and forms an acute angle with the axis of the conical surface forming the bottom wall. Thus, the surfaces are smooth and easily cleaned and do not provide cracks or crevices for accumulation of dirt and prevent anti-hygienic conditions from occurring. | ||||||
| 104 | Vacuum cuspidor | US82041 | 1979-10-05 | US4307475A | 1981-12-29 | Theodore E. Schmidt |
| The specification discloses an improved dental cuspidor having a vacuum drain means. The specification also discloses a drain having a drain chamber of which one side is formed by a diaphragm so that when water reaches a given height in the chamber, the diaphragm actuates an air valve to drive a piston to open a drain valve to a vacuum drain. | ||||||
| 105 | Portable cuspidor | US899138 | 1978-04-24 | US4165546A | 1979-08-28 | Alvin L. Philipson; Noel W. Abramson; Michael J. Woltcheck |
| A portable cuspidor supplied with rinse water and vacuum drainage through ganged flexible hoses has a hollow, enclosed cuspidor cup or bowl provided with a cushioned side wall opening against which facial areas surrounding the mouth of the patient or user are placed for expectorating. Interior rinse water jet streams are so directed and distributed against the interior of the cuspidor cup or bowl that substantially all of the rinse water, together with expectorant, will flow down for withdrawal at a drain orifice at the base of the bowl, no matter at what angle the device is being held for use. | ||||||
| 106 | Dental cuspidor with fluid recirculation system | US581059 | 1975-05-27 | US3964112A | 1976-06-22 | Richard E. Plowman |
| A water recirculation system is described wherein the discharge of one or more dental cuspidors is rendered reuseable and continuously used in the operation of a water sealed vacuum pump in a dental vacuum discharge system. | ||||||
| 107 | Apparatus for recycling a fluid for use in a dental cuspidor | US34597673 | 1973-03-29 | US3842448A | 1974-10-22 | LANGBERT C; KAHN S |
| Apparatus for recycling a fluid for use in flushing a dental cuspidor of the type having a bowl, a faucet for introducing the flushing fluid into the bowl and a drain in the bowl from which the fluid is conducted to the recycling system. The recycling system comprises means for separating sedimentary material from the fluid. After the sedimentary material has been separated from the fluid, the fluid is directed to a means for filtering the fluid. The filtered fluid is then pumped to a storage means which retains the fluid under pressure until it is conducted back to the cuspidor. The system includes means for backwashing the filter means as well as means for eliminating excess fluid from the sediment and filter means should fluid overflow occur therein. Also provided are means for partially or wholly bypassing the recycling portion of the apparatus to permit the introduction of a regulated amount of fresh fluid into the system.

| 108 | Cup for dental waste | US3765564D | 1971-05-21 | US3765564A | 1973-10-16 | PERSSON K |
| A dental cup for waste such as wads and pads of cotton wool, cement rests and the like, comprising a conical beaker made of a plastic foil and having an outwardly projecting flange at its edge. In the flange, there are at least two raised hollow portions defining a V- or U-shaped recess to enable a dental instrument to be applied in the recess and drawn rearwardly to scrape the waste against the edges of the recess.
