Abstract: A healing device applied to wounds, fistulas, pancreatitis, varicose ulcers, and other medical or veterinary pathologies includes a compacting chamber for covering the wound over the affected or diseased zone of the patient. The compacting chamber is defined by a self adhesive polymeric material laminar sheet, made out of a waterproof material. The compacting chamber has a replaceable mass of aerated polymer fiber flock therewithin, as a wound-stabilizing dressing. The compacting chamber uses a vacuum for deforming and compacting a mass of polymer fiber flock into effective healing contact with the wound. The vacuum means is terminated upon achieving compaction of the mass of polymer fiber flock and upon effective healing contact of the mass of polymer fiber flock with the wound.
