发明名称 Prophylactic device for a mouthpiece
摘要 A prophylactic device and associated method for preventing contamination between the mouth and a mouthpiece. The prophylactic device is a generally tubular structure, having a two open ends, that is made of a highly elastic and water impermeable material such as latex. The tubular structure is configured to conform to the contours of the mouthpiece as the mouthpiece is placed within the tubular structure. As the tubular structure is pulled over the mouthpiece, the tubular structure stretches and conforms to the mouthpiece, thus creating a watertight seal against the mouthpiece. When applied to a mouthpiece, the tubular structure covers the exterior surfaces of the mouthpiece. One end of the tubular structure is the folded into itself and is passed through the center of the mouthpiece, thereby protecting the interior surfaces of the mouthpiece. As a result, both the interior surfaces and the exterior surfaces of the mouthpiece are protected, thereby preventing all direct physical contact between the mouthpiece and a person's mouth and preventing any possibility of contamination between the mouthpiece and the mouth.
