The invention relates to the technical field of medical instruments, and discloses an artificial valve device. The artificial valve device comprises a support, the support is provided with a blood flow inflow end and a blood flow outflow end, and the blood flow inflow end and the blood flow outflow end are oppositely arranged in the preset direction. The stent comprises a plurality of net-shaped structure layers which are distributed layer by layer in the preset direction. The net-shaped structure layer at the blood flow-out end is a target net-shaped structure layer, and a connecting part of the target net-shaped structure layer protrudes towards the blood flow-in end; and/or the net-shaped structure layer at the blood flow inflow end is a target net-shaped structure layer, and the connecting part of the target net-shaped structure layer protrudes towards the blood flow outflow end. The artificial valve device further comprises a valve, and the valve is connected to the support. In this way, the axial positi
