A body fluid drainage device that includes a wedge-shaped reservoir evacuator which has a first sidewall and a second sidewall integrally formed and joined along a coextending common edge. A third collapsible bellows-shaped sidewall extends between the nonjoined edges and is sealed to the nonjoined edges of the first sidewall and second sidewall to enclose and form a fluid tight reservoir between the first, second and third sidewalls. An inlet port and outlet port are provided in fluid communication with the reservoir. A one-way valve is provided in the inlet port for permitting fluid flow into the reservoir but preventing fluid flow out of the inlet port. A spring element is provided for storing energy to force the first sidewall away from the second sidewall following compression of the first sidewall towards the second sidewall such that as the first sidewall moves away from the second sidewall a partial vacuum is created within the reservoir for drawing fluid into the reservoir.

A body fluid drainage device comprising: A wedge-shaped reservoir evacuator having a first sidewall and a second sidewall joined along a coextending common edge, and a third collapsible pleated sidewall extending between the nonjoined edges of the first sidewall and second sidewall to form a reservoir between the first, second and third sidewalls, the third sidewall having a collapsed position wherein the third sidewall is substantially positioned inwardly from the edges of the first sidewall and the second sidewall, wherein the third sidewall comprises a pleated sidewall with two sets of pleats extending from two apexes, the first apex being closer than the second apex to the common edge between the first sidewall and the second sidewall; an inlet port means in fluid communication with the reservoir for introducing fluid to the reservoir; a one-way valve means in the inlet port means for preventing fluid from flowing out of the reservoir through the inlet port means; an outlet port means in fluid communication with the reservoir for emptying fluid from the reservoir; and biasing means in the reservoir evacuator for biasing the first sidewall and second sidewall apart, such that following compressing the first sidewall towards the second sidewall, the first sidewall and second sidewall move away from each other creating a partial vacuum within the reservoir for drawing fluid into the reservoir.
