Abstract:
A continuous irrigation Y-tubing control valve device for medical applications, including transurethral resection procedures and other requirements demanding constant irrigation, which comprises:(a) a main housing, said main housing having a hollow body and having a top and a bottom; (b) an outlet located on and extending downwardly from said bottom of said main housing for attachment of distal delivery tubing thereto for liquid flow to a patient; (c) two inlets, being a first inlet and a second inlet, located on the top of said main housing and extending upwardly therefrom for attachment of proximal tubing to each of said two inlets; (d) a hollow, sealed floatation valve hingedly attached to and located within said main housing, said valve having a first, open position and having a second, closed position wherein said first open position of said valve allows liquid flow from both said first inlet and said second inlet to said outlet, and wherein said second, closed position allows liquid flow from said first inlet to said outlet and prevents liquid flow from second inlet to said outlet, such that when liquid flows while said floatation valve is in its first, open position, said main housing fills with liquid and said floatation valve rises to its second, closed position to permit flow only from said first inlet, and, when liquid flow from said first inlet ceases, said main housing empties and said floatation valve returns to an open position to permit flow from said second inlet to said outlet.
