The hypoxic environment is among the most important factors that complicates the healing of chronic wounds, such as venous leg ulcers, pressure injuries and diabetic foot ulcers, which seriously affects the quality of life of patients. Various oxygen supply treatments are used in clinical practice to improve the hypoxic environment at the wound site. However, problems still occur, such as insufficient oxygen supply, short oxygen infusion time and potential biosafety risks. In recent years, artificial photosynthetic systems have become a research hotspot in the fields of materials and energy. Photosynthesis is expected to improve the oxygen level at wound sites and promote wound healing because the method provides a continuous oxygen supply and has good biosafety. In this paper, oxygen treatment methods for wounds are reviewed, and the oxygen supply principle and construction of artificial photosynthesis systems are described. Finally, research progress on the photosynthetic oxygen production system to promote wound healing is summarized.

伤口缺氧环境与光合作用氧疗


缺氧环境是使腿部静脉性溃疡、压力性损伤和糖尿病足溃疡等慢性伤口愈合复杂化的最重要因素之一，严重影响患者的生活质量。临床上采用各种供氧治疗来改善伤口部位的缺氧环境。但仍存在供氧不足、输氧时间短、存在生物安全隐患等问题。近年来，人工光合系统已成为材料和能源领域的研究热点。光合作用有望提高伤口部位的氧气水平并促进伤口愈合，因为该方法提供了持续的氧气供应并且具有良好的生物安全性。本文综述了伤口的氧气治疗方法，阐述了人工光合作用系统的供氧原理和构建。最后总结了光合产氧系统促进伤口愈合的研究进展。
