Abstract
A wound drainage device is provided which includes a manually operable suction pump having inlet and outlet ports, and a pliable fluid storage bag having a pair of plastic sheets in face-to-face contact and an inlet. The pump inlet port is adapted to be connected to a wound suction catheter for removing drainage fluid from the wound. The pump outlet port is connectable to storage bag inlet for discharging drainage fluid into the storage bag without disconnecting the suction catheter. The bag has an upper foldable portion between the main storage portion and the bag inlet to close fluid communication to the bag and can serve as an added protection against drainage fluid flowing back to the suction pump. The storage bag can be used to receive drainage fluid and thereby provide a relatively large storage capacity without requiring a relatively large suction pump.
