新型电绷带提升慢性伤口愈合速度
近日，一项由科研团队开发的新型水激活电绷带（electric bandage）为慢性伤口愈合提供了一种快速、经济的解决方案。据IT之家了解，慢性伤口是指愈合缓慢或无法愈合的开放性伤口，如糖尿病患者常见的溃疡。这类伤口因其反复发作和增加截肢风险而成为医疗难题。传统治疗方案成本高昂，给患者带来了额外负担。
研究人员开发了一种廉价的电绷带，利用电场促进慢性伤口的愈合。在动物实验中，使用这种电绷带治疗的伤口比传统绷带治疗的伤口愈合速度快了30%。这种电绷带名为水动力无电子敷料（WPEDs），是一种一次性伤口敷料，配备有电极和小型生物相容性电池。敷料贴在患者身上，滴水激活后，电极产生电场，促进伤口闭合、新血管形成和减少炎症。
WPEDs设计独特，电极可随绷带弯曲贴合不规则深层伤口。研究团队在糖尿病小鼠身上测试了这款敷料，发现其加速了伤口愈合过程。重要的是，WPEDs的成本相对较低，每份敷料只需几美元。此外，患者可在家中轻松应用，无需长时间静养，更有可能遵循治疗方案。
研究人员表示，将进一步优化电场波动并延长电场持续时间，并推进更多测试，以使其更接近临床试验。这项研究已发表在《科学进展》杂志上。随着科技的进步，未来慢性伤口治疗有望变得更加高效和经济。

News Title: “New Electric Bandage: Accelerator for Chronic Wound Healing”
Keywords: Electric Bandage, Chronic Wounds, Healing Acceleration
News Content:
A new type of water-activated electric bandage developed by a research team has provided a fast and cost-effective solution for the healing of chronic wounds. According to IT Home, chronic wounds refer to open wounds that heal slowly or not at all, such as ulcers common among diabetics. These wounds are a medical challenge due to their repeated outbreaks and increased risk of amputation. Traditional treatment plans are expensive and impose additional burdens on patients.
Researchers have developed a low-cost electric bandage that uses electric fields to promote the healing of chronic wounds. In animal experiments, wounds treated with this electric bandage healed 30% faster than those treated with traditional bandages. This electric bandage is called a Water-Powered Electronic Dressing (WPED), a single-use wound dressing equipped with electrodes and a small biocompatible battery. The dressing is applied to the patient’s body and activated by drops of water, whereupon the electrodes generate an electric field to promote wound closure, new blood vessel formation, and reduce inflammation.
The WPEDs design is unique, with electrodes that can bend and conform to irregular deep wounds. The research team tested the dressing on diabetic mice and found that it accelerated the wound healing process. Importantly, the WPEDs are relatively inexpensive, costing only a few dollars per dressing. Additionally, patients can easily apply them at home without the need for extended rest, making it more likely for them to adhere to the treatment regimen.
The researchers stated that they will further optimize the fluctuation of the electric field and extend the duration of the electric field, and proceed with more tests to bring it closer to clinical trials. This study has been published in the journal “Science Advances.” With technological advancements, the treatment of chronic wounds in the future is expected to become more efficient and economical.
