Eye washing method and apparatus
First Claim
1. A method for washing an eye comprising:
- providing an eyecup having a rim portion that complementarily fits to the orbit portion which surrounds an eye on the face of a person;
placing the eyecup over the eye to form a liquid confining chamber adjacent the eye;
drawing the skin above and below the eye away from the eye;
pushing the eyecup against the skin such that the rim portion of the eyecup puts pressure on said skin above and below the eye for holding the eye open;
delivering liquid eyewash into the chamber and against a surface of the eye which is spaced a distance from the corneal portion of the eye to produce a washing action; and
draining the eyewash from the chamber.

Abstract
An eyecup (10) having a rim portion (14) that conforms to an orbit portion which surrounds an eye (12) on the face of a person is placed over the eye. The eyecup (10) forms a liquid confining chamber (45) adjacent the eye (12). The skin above and below the eye (20, 22) is drawn away from the eye (12), with the eyecup being pushed against the skin (20, 22) such that the rim portion (14) applies sufficient pressure against the skin for holding the eye (12) open. Eyewash is delivered and drained to and from the chamber (45) by inlets (50, 52) and an outlet (60). The inlets and the outlets are interchangeable. Eyewash delivered into the chamber (45) is directed such that the flow of the eyewash first contacts a surface of the eye (12) which is spaced a distance from the corneal portion (70) of the eye and then flows over and across the entire eye.

4. An apparatus for washing an eye comprising:
an eyecup which forms a liquid confining chamber adjacent an eye, said eyecup having a rim portion that complementarily fits to the orbit portion which surrounds an eye on the face of a person, said rim portion having a skin-contacting surface constructed so that, when said eyecup is placed over an eye, and is pushed in towards the eye, said rim portion will put pressure on the skin above and below the eye for holding the eye open, said eyecup further having at least one inlet in a wall portion of said eyecup for delivering eyewash to said chamber directly against the eye, and at least one outlet in a wall portion of said eyecup for draining eyewash from said chamber wherein said inlet is directed for delivering eyewash into the chamber such that the eyewash first contacts a surface of the eye which is spaced a distance from the corneal portion of the eye. - View Dependent Claims (5, 6, 7, 8, 9)
