发明名称 Clean hands assured
摘要 A device for assuring that restroom users are effectively reminded to wash and cleanse their hands. A spray pump is attached adjacent to an exterior door-handle to a restroom and is activated either by the turning of the handle or by the opening of the door. The spray pump includes a spray nozzle which sprays the user's front palm and/or back of the hand with a dye stain when the door-handle is opened. The dye stain is non-toxic fast drying and easily washable with cleanser such as soap and water. The dye stain can be visible in natural light and include colors such as red, yellow, blue and the like. Alternatively, the dye stain can be only visible to infrared light. The device can be used with round circular door-handles and lever door-handles. A shield around the door handle can discourage attempts to defeat the staining.
