Abstract: A hydrotherapy mechanical wound irrigation device for successful use with domestic water pressure service for the performance of wound self maintenance. The apparatus contains a body that is adapted to a domestic water connection, allowing for concurrent device and domestic plumbing fixture usage. The body contains a valve mechanism with lever for regulating flow through the device and spray nozzle whose specifications afford desirable impact pressures across the full range of domestic water pressures encountered.

Abstract: An optical data storage device protector comprised of two concentric rings. An outer ring is located near the outer periphery of the storage device and the inner ring's hole corresponds closely with the storage device's spindle hole. Both rings may be produced in a label sandwiched form having a peel away release liner, an adhesive that is preferably removable, a release coating facilitating removal of the release liner from the adhesive, a preferably high density face material that is adequately porous to receive a decorative finish and a face coating that serves to protect the decorative finish as well as to make the protector water resistant, UV light resistant and durable enough to withstand cleaning using either soap and water or wiper solutions available for device cleaning and reconditioning.
