Abstract

A reduced pressure treatment system includes a control unit having a control system and a reduced pressure source. The reduced pressure treatment system further includes a manifold unit in fluid communication with the reduced pressure source and a component module to augment treatment. The component module is configured to communicate with the control system of the control unit, and the component module includes a first mounting region configured to be coupled to a complimentary mounting region of the control unit. The component module further includes a second mounting region identical to the complimentary mounting region of the control unit to allow a second component module to be coupled to the first component module.
