Description
J- G. ASHTON DENTAL SPITTOON Jan. 4, 1966 le Jan. 2, 1963 INVENTOR- ./A6% a. ASA/70W 62% a. a/w
United States Patent 3,226,733 DENTAL SPITTOON Jack G. Ashton, 10011 Balboa Blvd., Northridge, Calif. Filed Jan. 2, 1963, Ser. No. 249,089 4 Claims. (Cl. 4-263) The present invention relates generally to a dental unit of the console type, and more especially to a spittoon therefor to be held when used by the patient.
A dental unit or console of the type here involved includes the necessary hand pieces and other operative accessories, together with their operating controls, to enable the dentist to carry on a wide variety of dental work on a patient. One of these accessories is the spittoon which, when not in use, is held by the console. The spittoon is provided with extensible and retractable connections to the console which permit it to be removed from the console and held in the patients hand during the period of use.
One object of the present invention is to devise an improved spittoon of the retractable type that may be held conveniently by the patient, thus eliminating the need for sitting up and leaning over a stationary bowl mounted on or near the dental chair.
Another object of the present invention is to provide a dental spittoon of this type which includes a continuously operating spray adapted to wash the spittoon clean.
A further object of the invention is to provide a dental spittoon of this type which has a disposable liner which may be quickly inserted and easily removed, thus presenting an attractive appearance to the patient and making maintenance of a sanitary condition possible with a minimum of eflort.
The above and other objects of the invention are attained by providing in a dental console having a panel provided with a receiver therein, a spittoon comprising a generally conical cup open at both ends, drain means connected to the lower end of the cup to carry away waste material, spray means within the cup to wash the spittoon clean, a water supply conduit connected to the spray means, and a disposable liner within the cup at a position where it is washed continuously by the water from the spray means, said liner being open at one end to receive waste material ejected into the spittoon and at the other end to discharge water and said waste material to the drain means. The drain means includes a length of flexible tubing connected to the cup, and the water supply conduit includes a length of flexible tubing inside the drain tubing, this arrangement permitting the spittoon to be removed from the receiver on the console and held by the patient at any selected position within a wide range of locations adjoining the console.
How the above objects and advantages of the present invention, as well as others not specifically referred to, are attained, will be better understood by reference to the following description and to the annexed drawings, in which:
FIG. 1 is a side elevation of a dental console showing the location the-rein of the dental spittoon;
FIG. 2 is a fragmentary vertical section through the upper portion of the cons-ole, on line 22 of FIG. 1, showing schematically the spittoon and the operational connections thereto;
FIG. 3 is an enlarged fragmentary median section through the spittoon on line 3-3 of FIG. 2;
FIG. 4 is a plan view of the spittoon of FIG. 3 with the liner in the cup;
FIG. 5 is a median section similar to FIG. 3 showing a variational form of spittoon; and
FIG. 6 is a plan view of the spittoon of FIG. 5.
Referring now particularly to FIG. 1, the dental console is indicated generally at 10. It comprises a cabinet Patented Jan. 4, 1966 11 which serves as a housing to enclose various fluid and electrical controls, conduits, connections, and other apparatus. The cabinet 11 is shown as mounted upon casters 12 which make the console easily movable around the patient.
The upper portion of cabinet 11 includes panel 14 which has a plurality of openings therein through which project the various hand pieces, accessories, and other devices utilized by the dentist in the treatment of patients. Without necessarily limiting the construction to these particular devices, hand pieces for various dental drills are indicated 15, an air and water syringe at 16, and the spittoon at 18.
As may be seen more clearly in FIG. 2, panel 14 has an opening therein at which is mounted a frusto-conical receiver 20 which is held in place by an interior support indicated at 21. Receiver 20 opens to the face of panel 11 and is adapted to receive and hold the spittoon indicated generally at 18. The spittoon is shown in receiver 20 in FIG. 2 which is the normal relation of these parts during the time when the spittoon is not in use.
Construction of spittoon 18 is shown in greater detail in FIG. 3 where it will be seen that the spittoon includes a generally frusto-conical cup 22 which is open at both ends. The lower or smaller end of the cup is provided with fitting 23 for connection to a suitable drain means provided in the form of flexible hose 25. Fitting 23 is normally welded or otherwise suitably connected in a permanent manner to cup 22, thus becoming a part of the cup. The taper of cup 22 is designed to match substantially the taper of receiver 20 so that the cup fits snugly within the receiver as shown. Within cup 22, suitable spray means are provided, typically taking the form of spray head 27 mounted upon the upper end of rigid metal tubing 28 which may be permanently and rigidly attached near its lower end to the cup. Tubing 28 is connected at its lower end to a flexible supply hose 29 through which water is supplied for spray head 27. The spray head is located centrally of cup 22, for reasons which will become evident. Positioned Within cup 22 is a disposable paper line-r 30 which, like cup 22, is frusto-conical in shape and open at both ends. The open larger end receives material ejected from the mouth of the patient, while the opening 31 at the smaller end of the cup enables the cup to pass over spray head 27 and a portion of tubing 28, thus locating the spray means centrally within the disposable liner. The water spray which issues from head 27 in all directions, washes the inside face of the liner 30 and carries away any waste material, the water and the waste material carried therewith being discharged through opening 31 in the liner into the lower end of cup 22 from which it passes at 33 into waste hose 25.
Also connected to junction block 35 is water supply line 37 flow through which is controlled by valve 38 which is preferably of the solenoid operated type. Water supply line 37 leads to a connection at junction block 35 with one end of flexible hose 29 which is located within the larger diameter flexible hose 25 and which is connected at its other end to rigid conduit 28. The flexible nature of the two hoses 25 and 29 permit the spittoon to be removed from the receiver 20 to any position near console 10, within the range of the length of hose 25, at which the patient desires to use the spittoon. The capa bility of the spittoon of being removed from receiver 10 to a position of use is indicated by the phantom line position of spittoon 18 in FIG. 1. When it is desired to return the spittoon to receiver 20, suitably weighted pulley means, indicated at 40, retracts the'hoses 25 and 29 into the cabinet.
In the embodiment of the invention illustrated in FIGS. 14, the major diameter of liner 30 is preferably slightly larger than the largest inside diameter of cup 22 so that when the liner is inserted in the cup, the rim of the liner is spaced from the rim of the cup. It may be preferable that the liner extend outwardly beyond the cup so that the user comes in contact with the liner rather than with the cup if the spittoon is held against the face. The liner being of paper or similar material is not cold to the touch and, therefore, more pleasant to feel than the metal cup. The user realizes that the disposable paper liner is replaced after each patient and is, therefore, clean and he feels confident that all desirable sanitary precautions are being observed.
The liner is more easily removed from the cup if the slope of the cup wall and the liner wall are different. This difference in slope results in contact between the two members over only a portion of the length of the liner, as shown in FIG. 3, and due to the liner having a small open bottom end, the suction or vacuum applied to the cup bottom will operate to retainingly hold the liner in its operative position.
A modified form of cup i shown in FIGS. and 6. Here cup 42. has a larger diameter at the open outer end than does cup 22. As a result, the liner 30, assuming that it remains of the same size, fits entirely within the boundaries of the cup.
While specific structural details have been shown and described, it should be understood that changes and alterations may be resorted to without departing from the spirit of the invention as defined in the appended claims.
I claim:
