Patent attributes
A fluid-management system for selectively draining fluid from a body cavity includes a valve assembly and a tube for carrying fluid from a body cavity of a person to the valve assembly. The valve assembly is configured to be positioned external to the person's body and comprises (i) an inlet, (ii) an outlet, (iii) one or more one-way valves positioned between the inlet and outlet that are each configured to open and close based on fluctuations in pressure between the person's body cavity and the one-way valve, and (iv) an adjustable outlet lock configured to selectively prevent fluid movement through the outlet.
