Abstract: An emergency water system testing system (20) is provided which includes a retaining tank (21) having inlet conduits (23 and 24), a vent (25), and an outlet conduit (26). The testing system also includes a support carriage (33) having four lockable wheels (34) and a flow measuring device (36). The system may be coupled to the coupler valve (14) of an emergency water system (12) so that water expelled from the emergency water system is contained on sight while the flow rate of the water is determined. In this manner the water expelled from the water system may then be moved to a remote location and controllably discharged.

Abstract: A drape is described for use in various ophthalmic surgeries including refractive eye surgery. The drape can be configured in at least sixteen different ways for both single or bilateral eye surgical procedures. The drape includes an adhesive liner that acts as a cover for the non-surgical eye. A tent portion is also provided that allows the patient to blink or comfortably keep open the covered non-surgical eye. Allowing the patient to blink or keep open the covered non-surgical eye gives support or assists in fixation of the surgical eye. The drape is also positions the apertures are on the lower half of the drape in order to leave the bottom of the nose and mouth uncovered for patient comfort. An adhesive liner may be provided with the drape for allowing coverage of the non-surgical eye.

Abstract: A capsulorhexis forceps is described which includes a unique removable hub and handle. The hub allows the use of the forceps as a cystotome in addition to a forceps. The hub design comprises a coaxial wire inside a cannula which provides minimal trauma when the forceps is opened and closed for repositioning during the capsulotromy. The hub is also replaceable and disposable after use. This flexibility in hub replacement allows the surgeon to use the forceps either in the initial open or closed position. The handle also may provide a constant grip force to the corneal flap independent of manual actuation force of the forceps.

Abstract: The ophthalmic surgical sponge is described which includes a base and a corneal shield assembly. The base allows absorption of corneal fluid during eye surgery. The corneal shield assembly is used as an absorption structure and a structure to protect the corneal cap which is formed during eye surgery, particularly in surgeries that remove tissue from the corneal stroma. The corneal shield assembly protects the corneal cap as well as the hinge of the flap during the actual tissue removal from either a laser or other tissue removing devices. Thus, the corneal cap is protected from scatter rays from the laser or other debris created from tissue removal of the cornea. Wetting the ophthalmic sponge creates a co-hesive seal so that the corneal shield assembly can seal the corneal cap securely. This seal is removable after the surgery is completed to re-expose the corneal cap and replace the cap on the cornea.
