abstract

This paper presents the fabrication and the test of an implantable two-way pressure regulation micro valve with the anti-siphon effect for the hydrocephalus patients. This micro valve consists of a silicone rubber membrane and a valve seat to enable the opening pressure control as well as the anti-siphon behavior. The two-way pressure regulation and the anti-siphon effect of the micro valve are shown experimentally for various sizes of membranes and valve seats.
