Fluid-Management System and Method

A valve assembly comprising:

• an inlet;
• an outlet;
• a plurality of one-way valves positioned between the inlet and outlet;
• and
• an adjustable outlet lock positioned downstream of the plurality of one-way valves and configured to selectively prevent fluid movement through the outlet, wherein the valve assembly is configured to (i) be positioned external to a body of a person and (ii) attach to a tube for carrying fluid from a body cavity of the person to the valve assembly.

A valve assembly comprising:

• an inlet;
• an outlet;
• one or more one-way valves positioned between the inlet and outlet, wherein each of the one or more one-way valves is configured to allow fluid movement in one direction during a fluid draining process and prevent retrograde flow during the fluid draining process;
• and
• an adjustable outlet lock positioned downstream of the one or more one-way valves and configured to selectively prevent fluid movement through the outlet, wherein the valve assembly is configured to (i) be positioned external to a body of a person and (ii) attach to a tube for carrying fluid from a body cavity of the person to the valve assembly.
