A wound drainage reservoir which is a container having a resilient sidewall that defines a chamber within the container and wherein an opening extends through the sidewall. A helmet extends through the opening, which helmet has an extending lip that engages a portion of the sidewall of the container which surrounds the opening. A collar encircles and is bonded to the helmet for sealing such a portion of the sidewall between the lip of the helmet and the collar. A first inlet is on the helmet to provide a first fluid-flow conduit to the chamber. A second inlet is on the helmet to provide a second fluid-flow conduit to the chamber. A drainage outlet is on the helmet to provide a fluid-flow conduit from the chamber. A plurality of ribs extend laterally along the sidewall.
