ABSTRACT:
A portable system for subatmospheric pressure therapy in connection with healing a surgical wound is provided. The system includes a wound dressing dimensioned for positioning relative to a wound bed of a subject, and a collection canister in fluid communication with the wound dressing. The canister includes a base defining a fluid receiving cavity and having a fluid inlet port and a vacuum port. The fluid inlet port is configured for fluid communication with a wound dressing. The system further includes a cover selectively engageable to the base, e.g., in a snap-fit manner. The cover is configured to receive a control unit and has a vent assembly for exhausting the control unit. A seal member is interposed relative to the base and the cover to establish and maintain a substantial sealed relationship between the two components when assembled.
