Inadequate oxygenation is one of the chief culprits for delayed wound healing. However, current oxygen therapies, such as hyperbaric therapy and topical therapy, face hurdles in providing sustained long-term to reverse hypoxia. Furthermore, their efficacy rejuvenating injury restricted by limited penetration bed. Herein, this study proposes a programmable portable device (named GUFO oxydevice) ingeniously integrating i) controllable generation unidirectional transmission system (COGT-UTS), ii) supramolecular assembled perfluorinated hyperbranched polymer/gelatin (GUF) hydrogel which polymer (FHBP) acts an reservoir ensure convenient replenishment thus directly regulate hypoxic microenvironment. Accelerating healing process oxydevice achieved both diabetic rat acute porcine model without any secondary tissue damages. The present demonstrates that holds promise practically feasible candidate treatment.
