Apparatus for draining surgical wounds is disclosed. One embodiment of the apparatus includes a disposable container to which a manual vacuum pump is releasably attached. The disposable container preferably includes an elastic bellows portion to provide a gauge of the subatmospheric pressure in the disposable container. The elastic bellows portion is preferably located in the neck of the container. The container may be rectangular or cylindrical. A suspension clamp for suspending the container from a bed sheet or a patient garment is also disclosed. Another embodiment of the container includes a vacuum chamber and a fluid collection chamber. The pump is in fluid communication with the vacuum chamber but isolated from the fluid collection chamber by a hydrophobic filter to prevent contamination of the pump with collected fluid. The advantages include an inexpensive, versatile, easy to operate wound drainage system which virtually eliminates the requirement for sterilization and the handling of wound drainage wastes, and the manual vacuum pump which may be operated to evacuate the container to any desired subatmospheric pressure which can be maintained or adjusted during postoperative use.
