Claim:
1. A wound therapy device, comprising: a wound dressing comprising: a source of negative pressure configured to apply negative pressure to the wound site through the wound dressing; and a coupling attached to the wound cover configured to fluidically connect the wound dressing to the source of negative pressure, through a vacuum connection; wherein when the wound dressing is applied to a wound site and negative pressure is applied by the source of negative pressure through the coupling to the wound cover, the liquid-retaining structure is configured to collect and retain liquid wound exudate and wherein a porous hydrophobic structure positioned between the liquid-retaining structure and the vacuum connection substantially blocks liquid from the liquid-retaining structure from flowing into the vacuum connection while the liquid-retaining structure simultaneously communicates negative pressure generated by the negative pressure source to the wound site.
