APPARATUS AND METHODS FOR CONTROLLING TISSUE OXYGENATION FOR WOUND HEALING AND PROMOTING TISSUE VIABILITY

摘要

A tissue oxygenation system for accelerating the healing of damaged tissue is disclosed. The system includes an electrochemical oxygen concentrator, a power management system, a pressure sensing system, and an oxygen flow rate/oxygen partial pressure monitoring and control system that operates to provide continuous variably controlled low dosages of oxygen to a wound site. An oxygen delivery tubing is connected to the device and includes a distal end that is positioned at or near the wound bed to provide oxygen to the wound site. The electrochemical oxygen concentrator is controlled with oxygen partial pressure information. A moisture absorbent dressing is positioned over the distal end of the tubing at the wound site and a reduced moisture vapor permeable dressing system covers the moisture absorbent dressing, distal end of tubing, and the wound site to create a restricted or occluded airflow enclosure.
