3 Claims. (01. 4-166) This invention relates to fountain eye baths and more particularly refers to an improved eye bath for continuously washing the eyes with copious amounts of flowing water.
Today, more than ever, becauseof the vas increase in industry, in factories, chemical plants, and 1aboratories,.there exists an increasing number of cases where foreign material lodges in the eyes. These substances are solid, liquid, vapors and gases. Washing the affected eye is the most eifective way of removing the foreign material; this is particularly true in the case of liquid, vapor and --gases where water washing the eyes is the only practical method of cleaning them. Bathing the eyes with water also dilutes as well as removes most chemical compounds. To eliminate the last traces of material, continuous flushing of the eyes for at least 5 minutes is recommended by most modern authorities. Thus, it will be appreciated, that when a chemical enters the eye, it should be flushed with water as quickly as possible and such washing should be continuous for long periods of time. 7
The conventional methods of bathing the eyes are crude and inadequate and consist primarily in rushing to the sink, scooping up handfuls of water and splashing it in the eyes. Another practice is to bathe the eye by means of an eye-cup which procedure has several disadvantages, namely, only One eye can be bathed by an eye-cup, too much time is consumed before water is applied to the eye, and only a small stagnant body of water treats the eye.
One object of the present invention is to provide a new and improved eye bath whereby copious amounts of flowing water continuously and simultaneously wash both eyes.
Another object of the invention is the employment of a valve with its motivating end disposed on the rim of the bowl in such manner that when the head rests on the bowl it causes the valve to open and release streams of water into the eyes.
Another object of the invention is to provide a substantially elliptical bowl circumscribing both eyes and depressed at its front end to'better fit the contour of the face.
Another object of the invention is to provide an eye bath whereby the discharge of water is disposed at points above the bottom of the bowl whereby an accumulation of water in the bottom of the bowl will not retard the upward flow of water. t
7 Another object of the invention is to provide an eye bath whereby the liquid inlet to thebowl first discharges into a reservoir to equalize the pressure thereby providing uniform discharge pressureof the liquid through each of the discharge nozzles,
An additional object of the invention is to provide an eye bath which is interposed in a circulating system of liquid whereby one or more different liquids such as physiological salt solution will flow from a source of supply to and through the discharge nozzles of the bowl to wash the eyes and thence through the drain of the bowl and returned to the source of supply.
A further object of the invention is to provide an eye bath whereby two apertures are spaced at a distance so that a separate stream of water is directed toward each of the eyes.
Other objects and advantages of the invention will be apparent during the-course of the following description:
In the accompanying drawings forming a part of this specification, and in which like numerals are employed to. designate like parts throughout the same:
Figure 1 is a plan view of the fountain eye bath. I t
Figure 2 is a front view of the fountain eye bath. I
Figure 3 is a cross sectional view of the fountain eye bath taken on line 33 of Figure 1.
Figure 4 is a cross sectional view of the fountain eye bath taken on line 4-4 of Figure 1.
Figure 5. is a plan view of the fountaineye bath shown in modified form.
Referringto'Figure 1, the bowl I is preferably shaped in an elliptical form sufficient to embrace the upper portion of the face and embrace both eyes. The width of the bowl may extend from approximately the center of the nose to the middle of the forehead. The length of the bowlshould be equal to or slightly exceed the width of the face. Of course, the'dimensions of the face varies with the individual but I have found that a bowl width 4 and a bowl length 6%.)" to be satisfactory for most faces. The advantage of having the bowl encompass only the upper portion of the face is that it leaves the individual bathing his eyes free to breathe easily through the nose and mouth and without the danger of having water splash those organs. I do not limit myself to these specific dimensions as they may be varied withoutdeparting from the scope of the invention. Bowl I may be constructed of any suitable r g d; material such as plastic, aluminum, Monel metal, or porcelain.
Mounted on the rim of bowl I is plate 2 on which is inscribed the word Push. When the forehead rests on the bowl, it pushes the plate 2 down which opens a valve shown in Figure 4 thereby releasing a flow of water. In this manner the necessity for speedily getting water to the eyes wherein. foreign material has lodged, is accomplished: Also, a continuous stream of water bathes' the eyes as long as the individual rests his head on the bowl. V
In certain special instances, an individual may desire to elevate his face slightly above the of l tive washing of the eyes or the individual may.
desire to insert his hands in the bowl for the purpose of diverting some water against the face which has been splashed with chemicals, particularly acidsand alkalist In these instances; the eye bath may be provided with a mechanism to actuate the flow of water in such manner that the hands are free ior insertion in the bowl, One method of accomplishing this result is to provide a root operated vale actuating means.-
Disposed inside and at each end or the bowl are two outlet nipples designated 3 and 4 on which are mounted protective caps 5 and 5; When plate 2 opens the valve water fiew's up wardly through the two outlets 3 and 4 in two streams in such manner that they are directed against the eyes. In the center of bowl i a drain I through which the overflow water is removed from the bowl. Drain I ma be provided with a guard 8 or screen to trap and prevent clogging of drain 1- by solid matter. Inlet 5 is connected to a sou-roe of water Interposed between the water supply andinlet 9 my be a pressure regulating device, not shown the drawing to control the force of the streams of water emitted from outlets 3 and 4.-
Figure 2 is: a front View or the ieuntam eye bath showing bowl I, plate 2, and drain I; It will be noted: that the front lip m ofbowl t is depressed for the purpose of allowing the nose to fit into the depression thereby permitting a snugger fit between the bowl and the contour oi the face' It desired, sponge may be fitted on to the bowl to givea softer" resting place for the face.
Figure 3 is a cross section. of. the eye hath taken omline 3-3 of Figure L Bowl t is so constructed that the two discharge outlets. 3; and k are elevoted to a level: above that of. drain L In this manner,an-y aecumulationof water inthe bottom of the bowl will not retard: the new or water mm the orifices 3 and 4. My preference is to have the two outlet nipples 3 and k with protective caps 5 and 6 inclined at an angle slightly toward one another.
Extending vertically down from plate 2 are two guide arms H- and 12 which are inserted in. holes l3 andld in lip of bowl. I thereby eliminating any tilting or rocking of plate 2. Extending flrom the bottom of bowl i and surrounding drain 1 is a wall [5r Attached to wall [5 by means of screws It is plate IT, thereby formin a reservoir" rs bounded by the bottom of b owi f. wail rs and plate H. Extending'tlirough' this reservoir [8" is conduit [9 connected to drain 1'. W'ater fronia suitable source of supply flows into reservoir l5 and discharges upwardly at the same bath taken on line 4-4 of Figure 1. Bowl I has mounted on its lip, plate 2 connected to arm 20 which, when plate 2 is depressed, opens any suitable spring loaded valve 2|. Water flows from inlet 9 through valve 2| and discharges into cavity l8. Water then is forced upwardly through nipple 3 and cap 5. The accumulation of water its bowl I is discharged through-drain- E and conduit l9.
Figure 5 is a plan view of an alternative form of eye fountain bath, with bowl 22, plate 23, water inlet 24, drain 25, guard 26, nipples 21 and 2B, and protective caps 29 and 30. The front wall 3| or bowl 22 is bent in a depressed inwardly direction to forni a recess 32 into which the bridge of the nose fits."
An alternative form of my eye bath, not illustrated in the drawings, comprises a series of vessels containing various medicinal liquids suitable for treating the eyes for different types of injuries, said vessel-s connected by conduit to the discharge nozzles of a bowl substantially as we 'viously described. The liquid accumulatin in the bowl passes through the drainor the bowl and thence returns" to the source of supply; Although mechanical means may be employed to force the liquid to circulate from the vessel to the bowl and returned to the veSseL- i prefer that the vessels bes-ufiiciently elevated to cause a free and copious fiow'oi liquid by gravity to the bowl. 7 The returnor liquid from the bowl to the vessel may be aecomplis'hed by a small centrifugal The vessels are fitted with-valves to'allow liquid from one or more of the-vessels to discharge into the bowl.
Fromthe foregoing, it will be seen that I have provided a fountain-eye bath'which will instantane ousl'y and continuously direct streams of flowin water into the eyes.
While I have shown and described a few em Bodiments of my invention; this is illustrative only and inno way limits the scope-of my invention. My invention is limited solely by and in the fol-- lowing claims in which I wish to claim the feet ture's inherent there Iclai'm: 1
