This concept is for several wound dressing conditions. Foremost to me is burn wound dressings. Burn patients suffer from pain when their dressings are changed. One use of this concept is to pump numbing and sterile gels in between the dressing and the wound. This can create an even hydraulic separation between the wound and the dressing that could help remove the dressing in a less painful way than peeling a dressing off of the wound.

Other such dressings can be made to flow gels and liquid agents through the dressing, over the wound and then evacuate the fluids from the wound. This flow can be continuous or intermittent. In cases of enzyme debridement, the agent can be pushed over the wound and then circulated which can result in faster results due to the possibility of continuously moving the debrided material away from the point of contact between the wound and the agent.

The cross section view shows a configuration that has a chamber with a gate to the area between the dressing and the wound. This chamber can be prefilled. The second chamber, when pressurized expands and forces the agent out of the dressing and onto the wound. The raised lobe separates the agent into individual chambers as the inflation of the pushing chamber progresses. This results in the agent being forced out evenly over the area of the dressing in spite of different resistances over the dressing area.

The advent of 3-d printing can supply numerous options in this area. Agents applied to a burn wound through the dressing and prior to removal of a dressing might not only ease the pain of the patient it could provide a barrier against infection as the wound is exposed to the air.
