    • A lockout valve for an inflatable penile prosthesis which responds to internal fluid pressure. The lockout valve comprises a housing having inlet and outlet ports, an interior chamber, an apertured valve seat, and a poppet biased toward the closed position. The inlet communicates with the prosthesis reservoir, and the outlet communicates with the interior chamber and the prosthesis pump. The housing includes a flexible diaphragm which moves toward the poppet when flexed inwardly. Fluid pressure through the inlet port urges the poppet into sealing engagement against the valve seat, therefore closing the lockout valve. Negative fluid pressure applied to the interior chamber from the outlet port (when the pump is actuated) causes the diaphragm to flex inwardly and contact the poppet to open the valve. The lockout valve operates like a check valve when subject to reverse flow.
    • 一种用于对内部流体压力作出响应的可膨胀阴茎假体的闭锁阀。 锁定阀包括具有入口和出口的壳体,内部室,有孔阀座和朝向关闭位置偏压的提升阀。 入口与假体储存器连通,并且出口与内部腔室和假体泵连通。 壳体包括柔性隔膜,当向内弯曲时,该隔膜向着提升阀移动。 通过入口的流体压力促使提升阀与阀座密封接合,从而关闭锁定阀。 从出口(当泵被致动时)施加到内部室的负流体压力导致隔膜向内弯曲并接触提升阀以打开阀。 当反向流动时,闭锁阀就像止回阀一样工作。
