Wound healing system using positive pressure to promote granulation at a tissue site

摘要

A wound healing system for promoting healing of a wound of a patient includes a positive pressure source, a reduced pressure source, and a porous foam positioned in contact with the wound. The porous foam includes a plurality of flow channels in fluid communication with the reduced pressure source. The system further includes a filler member having a flexible wall defining an interior chamber. The interior chamber is in fluid communication with the positive pressure source, and a cover member is positioned over the filler member.

1. A wound healing system for promoting healing of a wound of a patient, the system comprising:
a pump having an inlet and an exhaust, the inlet of the pump having a reduced pressure that is less than a reference pressure and the exhaust having a positive pressure that is greater than the reference pressure; a granulation-promoting material adapted to be positioned in contact with the wound and fluidly connected to the inlet of the pump; a filler member having an interior chamber fluidly connected to the exhaust of the pump; and a cover member adapted to be positioned over the filler member to secure the filler member at the wound.
