研究目的:

通过利用控释型双层敷料吸收和再释放生长因子的生物特性,吸收PRP爆发性释放的部分生长因子,并在PRP代谢后利用浓度梯度缓慢持续释放生长因子,尝试延长单次PRP治疗在创面的作用时间,持续促进肉芽组织生长,加快伤口愈合进程,减少换药次数。通过收集对比常规PRP治疗、PRP联合控释型双层敷料治疗慢性难愈性创面患者的各种指标的变化,评价PRP联合控释型双层敷料在慢性难愈性创面中的临床应用效果和价值。  

Objectives of Study:

By utilizing the biological characteristics of controlled release double-layer dressings to absorb and re release growth factors, partial growth factors released by PRP are absorbed, and growth factors are slowly and continuously released using a concentration gradient after PRP metabolism. This is an attempt to prolong the duration of a single PRP treatment on the wound, promote granulation tissue growth, accelerate the wound healing process, and reduce the number of dressing changes. By collecting and comparing the changes in various indicators of conventional PRP treatment and PRP combined with controlled release double-layer dressing treatment for patients with chronic refractory wounds, evaluate the clinical application effect and value of PRP combined with controlled release double-layer dressing in chronic refractory wounds.
