ABSTRACT:
A medical device valving mechanism comprising a molded plastic, one-piece, elongated valve body molded to have a longitudinally extending body shaped to be gripped and securely held in either hand leaving the hand's thumb free for valve operational movement. The body has at least one fluid passageway extending longitudinally therethrough and a cylindrical opening extending transversely therethrough to intercept the at least one passageway. A cylindrical molded plastic, one-piece rotor for snug slidable and rotational insertion into the cylindrical opening to block the at least one passageway is provided. The rotor has at least one transaxial passageway which opens the at least one fluid passageway through the valve body when the rotor is in its valve opening position and which closes the at least one fluid passageway when the rotor is in its valve closing position. A thumb-actuated means is provided for rotating the rotor, the actuated means is disposed above the valve body and the rotor for convenient thumb movement.
