1. A wound therapy device, comprising:
a vacuum source module comprising a housing, and a vacuum source and a pressure controller within the housing, the vacuum source capable of generating negative pressure and the pressure controller configured to control the amount of negative pressure generated by the vacuum source;
a dressing module comprising:
a flexible wound cover to cover at least a portion of a wound site;
a porous liquid collector positioned within the flexible wound cover and configured to be in communication with the wound site, wherein said porous liquid collector is configured to retain wound exudate while simultaneously communicating negative pressure generated by the vacuum source module to the wound site;
a seal for sealing the dressing module to a surface around the wound site; and
a coupling for maintaining the housing of the vacuum source module integral with and in communication with the dressing module, the coupling comprising an adhesive on the vacuum module configured to adhere the housing of vacuum source module to the dressing module, wherein the coupling comprises a lip of the vacuum source module.
