Improvements in and relating* to Instruments for Treating* and Operating on tlie Eyes. I, James Bainbridge, of 18 Helen Street, Govan, Lanarkshire, Engineer, do hereby declare the nature of my invention to be as follows :— This Invention has reference to improvements in and relating to instruments for treating and operating on the eyes, with the object of causing by what is known as 5 “dry cupping” a proper amount of blood to circulate through the eyes, and restore the diminished convexity of the cornea of the eyes, and thus cure long-sightedness, dimness of vision, weakness of sight, short-sightedness and other diseases ot the eyes. And which instruments will be a great improvement over the ivory cup and india- rubber ball appliances heretofore in use, as the suction, tension, and pressure equally 10 on both eyes can be regulated to the extent desired, while the cup attachments can be placed on the cornea of the eyes in a more equal and reliable manner. According to my invention I use two cups, of hollow conoidal or cylindrical shape, with plain edges, or curved at their outer edges concavely to the convex shape ot the eye, and made of ivory, wood, vulcanite, horn, or other material, and I joint or 15 connect to the hollow stems of these, the ends of flexible tubes preferably ot india- rubber, and joint or connect the other ends of these flexible tubes to the duplex branches of a central hollow or tubular mouthpiece, or the two flexible tubes might bo joined to one tube, provided with a mouth-piece. The instrument thus formed, is used as follows ;—the mouth-piece is placed in the 20 mouth, and the outer open edges of the hollow cups are placed air-tight over the eyes to be dry cupped, and the person sucks the mouth-piece, the suction of which, through the flexible tubes, will remove the air from the cups and cause a partial vacuum and retain the cups on the eyes, and draw the cornea ot the eye to the proper convex or spherical form and feeling of comfort by the person, the tongue 25 acting as a valve on the end of mouthpiece to retain the suction. hen desired the newT or improved instrument can be made for operating only on one ey e at a time, by using only one hollow eye-cup attached to a flexible tube with a mouth-piece on the other end of tube.
