Abstract
Abstract An improved dual channel cap for use in conjunction with either a first or a second endoscopic channel valve or equivalent includes a main body portion having a first female opening suitable for mating with the first Olympus type endoscopic channel valve. A second female opening suitable for mating with the second Olympus type endoscopic channel valve is diametrically opposed to the first female opening. A slit couples the first female opening to the second female opening. A plug portion has a first male member suitable for mating with the first female opening. A second male member suitable for mating with the second female opening is diametrically opposed to the first male member. A first and a second channel passes through the first and second male members respectively, the first and second channels being coupled together with a slit. A strap connects the main body portion to the plug portion.
