Abstract:
The CSF shunt valve includes an elongate, hollow housing and a valve unit disposed within the housing. A plurality of exit ports are formed along the wall of the housing, and a plurality of bleeder ports are formed on the bottom of the housing. The valve unit includes at least one regulating mechanism disposed within the housing. Each regulating mechanism includes an obstructing member operatively attached to a spring. The spring is compressible within a predefined range of fluid pressure. The obstructing member compresses the attached spring in response to fluid pressure acting thereon, opening the exit ports for fluid being drained. The spring-biased obstructing members facilitate self-adjustment for drainage flow. Although arranged in series, the range limits are not continuous with subsequent springs, which safeguards against transient spikes in fluid pressure and ensures independent compression of subsequent springs in response to the predefined limits of pressure for that spring.
