5 Claims, 4 Drawing Figures PATENTED FEB] 1 I975 SALIVA EJECTOR BACKGROUND OF THE INVENTION This invention relates to dental appliances. More particularly, this invention relates to means for removing saliva, water, and the like fluids from the oral cavity of a patient undergoing dental treatment.
It is an object of this invention to provide a pliant, light-weight saliva ejector which is more comfortable to the patient and which provides greater access to fluid accumulation areas within a patient's mouth.
Another object of this invention is to provide a saliva ejector which has improved lateral flexibility.
Yet another object of the present invention is to provide a saliva ejector'which can be held more comfortably in a patients mouth at any reclining angle of the patient.
SUMMARY OF THE INVENTION This invention contemplates a pliant, light-weight saliva ejector for a patient which comprises a tubular stem provided at one end with an end portion in the shape of an inverted U and a hollow, flexible collector head mounted on the end portion and communicating with the tubular stem. The tubular stem also communi cates with an aspirator means. The collector head is provided with a plurality of spaced perforations for inducting saliva therethrough and with a plurality of substantially parallel accordion pleats in an outer wall of the collector head, thereby providing adaptability for said collector head to physical features of a patients mouth.
BRIEF DESCRIPTION OF THE DRAWING In the drawing,
FIG. 1 is a side elevational view of a saliva ejector embodying the present invention;
FIG. 2 is a plan view, partly in section, taken along line 2 2 in FIG. 1.
FIG. 3 is an end elevational view of a collector head embodying the present invention; and
FIG. 4 is a cross-sectional view of the collector head shown in FIG. 1 and taken along line 3 3.
DESCRIPTION OF PREFERRED EMBODIMENTS Referring to FIG. 1, saliva ejector comprises tubular stem 11 having end portion 12 shaped as an inverted U. Hollow, elongated collector head 13 is mounted on end portion 12 so that boss 14 abuts flange l5. Dimensions of end portion 12 are chosen so that the inverted U rests upon the patients jaw and so that tip 16 of end portion 12 terminates above the floor of the patients mouth. Tip 16 can also be provided with retainer ring 17 which is received within complementary groove 18 situated in the bore of boss 14 so that collector head 13 can be rotated relative to end portion 12 to a position more comfortable to the patient.
As can be best seen in FIGS. 2, 3 and 4, outer wall of elongated collector head 13 is provided with a plurality of accordion pleats 21 which are substantially parallel relative to each other and which extend in a longitudinal direction about the periphery of collector head 13. Accordion pleats 21 substantially contribute to the lateral flexibility and compressive elasticity of collector, head 13 as well as make the ejector more comfortable in the patients mouth. Preferably grooves between adjacent accordion pleats in the side wall have an included angle of about 60 degrees.
It is preferable that collector head 13 is longer than it is wide. i.e., the length-to-width ratio of collector head 13 preferably is greater than 1. Such dimensions, in combination with accordion pleats 21, permit distortion of collector head 13 within patient's mouth without impairing the saliva removal capability thereof and without discomfort to the patient. For example, the tip portion of collector head 13 can be bent upwardly as much as about degrees and downwardly as much as about 60 degrees, thereby effecting a front-to-back plane change and compression of collector head 13 without applying much force and without discomfort to the patient. Accordion pleats 21 also permit substantial lateral flexing and vertical flexing. The available flexing planes permit simultaneous multidirectional flexing of collector head 13 and thus provide excellent adaptability to the contours of a particular oral cavity.
A preferred material of construction for collector head 13 is relatively soft latex rubber. However, other materials having similar softness and resilience characteristics are also suitable. Tubular stem 11 and end portion 12 preferably are made of stainless steel; however, other materials such as chrome-plated copper tubing, polyethylene tubing, and the like are also suitable.
The saliva ejector of this invention is used by connecting tubular stem 11 to a suitable aspirator means and by placing collector head 13 in a comfortable position in the patients oral cavity below the tongue so that end portion 12 rests upon, or is supported by, the lower jaw of the patient.
The foregoing discussion and the drawing are intended to be illustrative of the present invention and are not to be taken as limiting. Still other variations are possible without departing from the spirit and scope of this invention.

A pliant, light-weight saliva ejector for a patient comprising a tubular stem adapted for communication with an aspirator means and having an inverted U-shaped end portion adapted to rest upon the lower jaw of said patient and terminating above the floor of said patients mouth, and i a hollow, flexible, elongated collector head mounted on said inverted U-shaped end portion in communication with said tubular stem and adapted to be received in said patients mouth;

2. The saliva ejector in accordance with claim 1 wherein the collector head is made of latex rubber.
3. The saliva ejector in accordance with claim 1 tion near one end of the collector head. wherein vertical grooves between said accordion pleats 5 The saliva ejector in accordance with claim 1 have an included angle of about 60 degrees. wherein said flexible collector head is rotatably 4.
