Bi-directional valve device for selective control of fluid flow through multiple converging paths
Hand-operated suction and irrigation medical devices are provided. An example medical device comprises a housing having a proximal end and a distal end. The housing defines first and second inlet paths and an outlet path. A first tubular member is partially disposed within the first inlet path and a second tubular member is partially disposed within the second inlet path. Each of the first and second tubular members extends from the proximal end of the housing. A third tubular member is partially disposed within the outlet path and extends from the distal end of the housing. A control member is slidably disposed on the housing and is movable between a first, proximal position and a second, distal position. A passageway provides fluid communication between the first inlet path and an opening to an environment external to the housing such that covering the opening provides control over the flow of fluid through the first inlet path and the first tubular member.
