UNITED STATES WILHELM STRUNZ, OF ALLERSBERG, NEAR NUREMBERG, GERMANY.

APPARATUS FOR. WASHING THE EYES.

Application filed July 12, 1926. Serial No. 121,993, and in Germany September 7, 1925.

This invention relates to an apparatus for washing the eyes for preventing and curing eye-diseases and it has for its object to improve. apparatus of that type in which the liquid is brought onto the eye with the aid of a compressible rubber ball connected with the washing basin. In order to ensure a good healing effect it is necessary to wash the whole e ve ball by means of very thin jets of liquid. Care has to be taken that, at the compressing or'therubher ball,no air is blown onto the sensitive eye and that the washing liquid flowing oli' the eye does not flow over the rose and prevents the formation of the thin jets but is colleeted at the sides of the rose. The washing apparatus must be of small size so that it can be carried in the. pocket.

The apparatus according to the invention is constructed so that the rose and the washing cup can be easily exchanged.

An embodiment of the invention is shown, by way of example, in the accompanying drawing in which Fig. 1 shows the apparatus in vertical section and Fig. 2 in plan view.

In the neck of the rubber ball 1 a stopper 2 is inserted which has a central bore enlarged at the top end. The neck of the rubber ball is securely held on the stopper by means of a ring 3. The top portion of the stopper 2 is set off so that an annular shoulder 4 is formed in which rest-s a rubber ring 5. The lower edge of the washing cup rests upon this rubber ring 5. The top portion ofstopper 2 isexternally threaded and the cap shaped rose. 7 is screwed onto this threaded portion of the stopper. The lower edge of the rose 7 is bevelled in inward direction and presses upon a shoulder in the bottom part of the washing cup 6 to hold this cup securely on the rubber disk 5. The rose 7 has very small holes 10 in its top surface. The rose is of such small diameter that an annular space 8 is formed between its outer wall and the inner wall of the washing cup, the washing liquid dropping back from the eye being collected in this space 8.

In the bore of the stopper 2 a tube 9 is located which extends to close over the bottom of the rubber ball 1. Owing to this tube 9 the air over the liquid in the ball cannot be admixed with the liqnid so that no air is contained in the thin ]QtS of liquid. As the jets of liquid are forced out under pressure the liquid penetrates under the eyelid and washes the entire surface of the eye ball.

To fill the liquid into the rubber ball the rose is screwed off the stopper. Into the sides of rose 7 notches 11 (Fig. 2) are cut designed to receive a key to facilitate the unscrewing of the rose. If the rose has been removed the working cup can be exchanged against a washing cup which tightlyiits onto the eye. If thinner jets of liquid are wanted than usual a rose 7 having smaller holes can be inserted.

I claim '1. An apparatus for bathing eyes, comprising in combination a rubber ball to be compressed by hand containing the washing liquid, and a fiat cap having in its top plate a great number of narrow holes arranged so that they are directed towards the whole sur face of the globe of the eye.

2. An apparatus as specified in claim 1, comprisingin combination with the rubber ball and with said flat cap, arising pipe in said rubber ball communicating with said flat cap.

In testimony whereof I afiix my signature.

VILHELM STRUNZ.
