Abstract: A flexible, compressible reservoir draws a substantially constant vacuum to permit uniform removal of fluid from a surgical incision through a wound drain catheter. The reservoir includes a compression spring interposed between a pair of congruent articulated plates. The spring provides biasing force to expand the reservoir and create a vacuum therein. Each of the articulated plates has a central member hinged on opposite sides to wing members. As the reservoir expands, the wing members pivot relative to the central members to decrease the effective area to which the spring force is applied. Such decrease in the effective area permits the spring force per unit of area to remain more nearly constant, and thus, reduces changes in reservoir vacuum.
