Valve Position Detection |
| 摘要 |
A valve system for an ocular implant device includes a boss structure. The boss structure includes an inlet for fluid inflow, and a number of outlets for fluid outflow. The valve system further includes a deformable membrane positioned over and spaced apart from the inlet, the membrane comprising a piezo-based material, an actuating element to apply pressure to the membrane to deform the membrane into a position that obstructs fluid flow from the inlet, and a control system to detect a position of the membrane based on measured electrical properties of the membrane. |

1. A valve system for an ocular implant device, the valve system comprising:
a housing; a boss structure connected to the housing, the boss structure comprising an inlet for fluid inflow; a number of outlets within the housing, the outlets for fluid outflow; a displaceable membrane positioned over and spaced apart from the inlet, the membrane comprising a piezo-based material; an actuating element to displace the membrane into a position that obstructs fluid flow from the inlet; a control system to detect a position of the membrane based on measured electrical properties of the membrane. |
