Chronic skin wounds affect millions of people each year and take billions of dollars to treat. Ulcers are a type of chronic skin wound that can be especially painful for patients and are tricky to treat because current monitoring solutions are subjective. We have developed an impedance sensing tool to objectively monitor the progression of healing in ulcers, and have begun a clinical trial to evaluate the safety and feasibility of our device to map damaged regions of skin. Impedance data has been collected on five patients with ulcers, and impedance was found to correlate with tissue health. A damage threshold was applied to effectively identify certain regions of skin as "damaged tissue".
慢性皮肤伤口每年影响数百万人，治疗费用高达数十亿美元。溃疡是一种慢性皮肤伤口，对患者来说可能特别疼痛，而且由于目前的监测方法主观，治疗起来很棘手。我们开发了一种阻抗传感工具，用于客观监测溃疡的愈合进程，并已开始一项临床试验，以评估我们的设备绘制皮肤受损区域的安全性和可行性。已收集了五名溃疡患者的阻抗数据，发现阻抗与组织健康状况相关。应用损伤阈值有效地将皮肤的某些区域识别为“受损组织”。
