PRESSURE REGULATING BUOYANT VALVE FOR A SHUNT SYSTEM |
摘要 |
A gravitational pressure regulating valve to regulate fluid flow of a patient, including a fluid chamber having an inlet port to receive a bodily fluid and an outlet port to discharge received bodily fluid, the fluid chamber including a first chamber configured to capture a non-buoyant member therein and to guide the non-buoyant member along a longitudinal axis of the first chamber to facilitate bi-directional reciprocating movement of the non-buoyant member to and from the inlet port, and a second chamber configured to capture one or more buoyant members therein such that when the second chamber is filled with bodily fluid, at least one of the buoyant members applies a resolved buoyant pressure from a buoyant force of the one or more buoyant members in opposition to an inlet pressure of fluid at the inlet port. |

1. A gravitational pressure regulating valve to regulate fluid flow of a patient, comprising:
a fluid chamber having an inlet port to receive a bodily fluid and an outlet port to discharge received bodily fluid, the fluid chamber comprising:
a first chamber configured to capture a non-buoyant member therein and to guide the non-buoyant member along a longitudinal axis of the first chamber to facilitate bi-directional reciprocating movement of the non-buoyant member to and from the inlet port; anda second chamber configured to capture one or more buoyant members therein such that when the second chamber is filled with bodily fluid, at least one of the buoyant members applies a resolved buoyant pressure from a buoyant force of the one or more buoyant members in opposition to an inlet pressure of fluid at the inlet port. |
