Jan. 11, 1949.' Au REHN EYE SPRAY Filed. Jan. 16, 1946 INVENTOR. AAM/A REHA/ ATTORNEYS Patented Jan. 11, 1949 UNITED STATES PAT-ENT lOFFICE EYE SPRAY Anna Rehn, New York, N. Y. Application January 1,6, 1946, Serial No. 641,503
rIhis invention relatesr to eye sprays and has for its object the provision of an eye spray for spraying the eyelids with medicated liquids' or water to medically treat the lids and surrounding tissue, and/or to massage them to induce increased circulation and stimulate the activities of the associated muscles and tissues.
Other objects will be apparent from the following specication and drawings wherein is described and illustrated a preferred embodiment of the device by way of illustrating the invention. Once the inventive concept is perceived, many changes in details may be made without, however, departing from the scope of the appended claims. i
In the accompanying drawings:
Figure 1 is a View looking down on the top of the device;
Figure 2 is a side elevational View of the def vice, Figure 1;
Figure 3 is a sectional view on the line 3, 3 of Figure 2,'
Figure 4 is an enlarged View of one of the nozzles of the device;
Figure 5 is an end View of one of the jet members used in the nozzles, Figure 4; and
Figure 6 is a front View of the nozzle, Figure 4.
The body, or frame, of the device comprises a handle I0, a support II for the guard, and Y- shaped extensions I2, I3 for supporting the nozzles lll, I5. These parts are preferably cast in one piece in suitable material such as Lucite, Bakelite, or any other plastic, or may be cast inany suitable material or fabricated from several pieces secured together in any manner.
The handle I at its lower end has a threaded opening l `adapted to receive the usual bushing or coupling whereby the usual liquid supply tube is connected to supply liquid to the duct I'I in the handle.
A valve IB of any suitable construction is provided in the handle to control the flow of liquid through duct Il. The upper end of duct I1 com municates with the transverse duct I9, the outer ends of which terminate at 20, 2l within the nozzles i4, I5 as presently described.
A short neck 22 connects the handle l!) with the extensions I2, I3 and extends inwardly from the support II.
As the nozzles I4, I5 are identical, only one of them will be described in detail. Referring to Figure 4, the nozzle I4 has a body portion 23 threaded at 2d to engage the externally threaded outer end portion 25, of the extension I2. A flange, or shoulder 26 is provided on the member I2 against which the body 23 is seated when same is yiirmly screwed in place. v
yThe lccdy 23 .when in place on the member i2 -is so proportioned that a main chamber 2l exists within the body in liquid communication with the mouth 25 of duct I9.
The body has a front wall 28 which may be slightly concave on its outer surface as shown, and this wall is drilled or formed with a plurality of pockets 29 to receive jet members 30.
The body of each jet member has a helical groove 3l on its outer longitudinal surface. This groove starts at 32 at the inner end of the jet member and terminates at 33 on the outer end thereof.
Each jet member is pressed or otherwise secured in its pocket 29, leaving a secondary pocket or chamber or cavity 34 between the outer end of the jet and the inner side of the front wall 28.
Each cavity 34 has a small opening 35 in liquid communication therewith and extending outwardly through wall 28.
A suitable guard or shield is provided having an upper portion 36 and end walls 3l, 38, and a vertical rear wall 39. This guard may be made integral with the support I I, or may be made separately therefrom, from any suitable plastic such as Lucite, or any other suitable material, and secured to the support II by any means, such as rivets 4l).
In use, the front edge 4I of the guard is brought against the users forehead immediately above the nozzle, thus positioning the nozzles lli, I5 the proper distance from the users eyes.
The valve I3 is depressed, permitting fluid to pass upwardly in duct Il. The chambers 21 fill with fluid, which is forced outwardly through the tortuous paths formed by grooves 3l and into the pockets Sil and outwardly therefrom through the small openings 35. The iiuid, it will be understood, is under pressure, such for example as the pressure of the city water system, of from l5 to pounds per square inch, and by reason of the chambers 21, 3a and the tortuous paths 3l therebetween the pressure of the fluid is reduced and the iiuid is reduced to a fine mist-like spray that impinges upon the eyelids and the surrounding tissues of the external eye socket, gently massaging same.
By medicating the water, or applying other medicinal fluids, various applications may be applied in the manner just described.
If desired, the valve I8 can be placed anywhere in the device, for example in the ball-top '42, or can be placed in the threaded end I6 of the handle, or in the supply pipe or tube communicating therewith. 4
What is claimed is:
1. In a device of the character described, a support forming a casing, a pair of nozzles mounted on said support, each of said nozzles hav ing a chamber therein, each of said nozzles having a plurality of jet members, each of said jet members having a helical passage therein in communication with the chamber Within its associated nozzle, said nozzles being spaced a pupillary distance apart, a duct member supported in said casing and in liquid communication with the chambers in said nozzles, a handle attached to said support, and means for supplying liquid to said nozzles Via said duct member producing a mist-like spray emanating from said jet members.
2. A device of the character described, a support forming a casing, a pair of nozzles mounted on said support, each of said nozzles having a chamber therein and a plurality of jet members, each of the jet members being provided with a helical groove in its outer longitudinal surface forming with the casing a tortuous passage in communica- 4 tion with the chamber within its associated nozzle, said nozzles being spaced a pupillary distance apart, a duct member supported in said casing and in liquid communication with the chambers in said nozzles, a handle attached to said support, and means for supplying liquid under pressure to said nozzles via said duct member producing a mist-like spray emanating from said jet members.
