研究目的:

1.比较自制便携式VAC装置与标准VAC装置治疗慢性创面的临床疗效,验证其非劣效性。 2.比较两组患者的经济成本、治疗的安全性以及对患者生活质量的影响。  

Objectives of Study:

1. Compare the clinical efficacy of homemade portable VAC devices with standard VAC devices in the treatment of chronic wounds, and verify their non-inferiority. 2. Compare the economic costs, treatment safety, and impact on patients' quality of life between the two groups of patients.

1.年龄≥18岁,性别不限。2.符合慢性创面诊断标准:各种原因导致的创面,经规范治疗4周以上仍未完全愈合。3.创面类型包括:糖尿病足溃疡、下肢静脉/动脉性溃疡、压力性损伤(2-4期)、创伤性溃疡、术后难愈性创面。4.创面面积在4cm2至100cm2之间,深度适宜进行负压治疗。5.自愿参加并签署知情同意书。

Inclusion criteria

1. Age >= 18 years, any gender. 2. Meet the diagnostic criteria for chronic wounds: wounds caused by various reasons that have not completely healed after more than 4 weeks of standard treatment. 3. Types of wounds include: diabetic foot ulcers, lower limb venous/arterial ulcers, pressure injuries (stages 2-4), traumatic ulcers, and post-surgical hard-to-heal wounds. 4. Wound area between 4 cm^2 and 100 cm^2, with a depth suitable for negative pressure therapy. 5. Voluntarily participate and sign the informed consent form.

排除标准:

1.癌性创面、活动性出血创面、未彻底清创的感染创面;2.创面暴露有重要血管、神经、肌腱或内脏器官;3.对本研究使用的任何敷料或材料(如硅胶、纱布等)过敏者。4.妊娠或哺乳期妇女。5.合并严重全身性疾病(如凝血功能障碍、未控制的全身感染、严重低蛋白血症等),研究者判断不宜参加者。

Exclusion criteria:

1. Cancerous wounds, actively bleeding wounds, or infected wounds that have not been thoroughly debrided; 2. Wounds exposing important blood vessels, nerves, tendons, or internal organs; 3. Individuals allergic to any dressings or materials used in this study (such as silicone, gauze, etc.); 4. Pregnant or breastfeeding women; 5. Individuals with severe systemic diseases (such as coagulation disorders, uncontrolled systemic infections, severe hypoproteinemia, etc.) who are deemed unsuitable to participate by the researchers.

盲法:

由于两种装置外观差异显著,无法对操作医生和患者实施盲法。但将对结局评估者(负责测量创面面积、评估愈合时间、统计不良事件的研究人员)和数据统计分析师实施盲法,以减少测量和评价偏倚。

Blinding:

Due to the significant differences in the appearance of the two devices, it is not possible to blind the operating doctors and patients. However, outcome assessors (researchers responsible for measuring wound area, evaluating healing time, and recording adverse events) and data analysts will be blinded to reduce measurement and evaluation bias.
