OPTICAL DETECTION OF INTRAVENOUS INFILTRATION

美国约80%的住院患者需要静脉注射治疗 50%的静脉输液管道失败是由于渗透、插管内的血块和 静脉的炎症反应，或导管与静脉的分离。 静脉浸润通常伴有疼痛、红斑和/或肿胀。 插管尖端或插入部位。严重的渗透可能会导致坏死。 需要清创、植皮或截肢。早期发现 渗透可防止可能需要 手术矫正。这项研究的第一阶段目标是开发一种光学 检测静脉渗透并展示其敏感性的技术 技术达到或超过视觉和触觉检查的技术 训练有素的观察员。在第一阶段，将开发一个原型设备，并 该技术的可行性将得到论证。第一阶段的研究将 包括对测量结果的分析，以确定何时向医疗保健发出警报 供应商和报警手段。第二阶段的研究将包括 重症监护新生儿应用技术的调查分析 布景。 建议的商业应用：不可用

About 80 percent of hospital patients in the United States require IV therapy and 50 percent of IV lines fail due to infiltration, a clot in the cannula, an inflammatory response of the vein, or separation of the cannula from the vein. IV infiltration is usually accompanied by pain, erythema, and/or swelling at the cannula tip or the insertion site. Severe infiltration may lead to necrosis requiring skin debridement, skin grafting, or amputation. Early detection of infiltration prevents the occurrence of serious incidents that may require surgical correction. The Phase I aim of this research is to develop an optical technology for detecting IV infiltration and demonstrate the sensitivity of the technology at or better than that of visual and tactile inspection performed by trained observers. In Phase I, a prototype device will be developed and feasibility of the technology will be demonstrated. The Phase I research will include an analysis of the measurements to determine when to alert healthcare providers and the means of alarming. The Phase II research will include an investigation of the technology applied for neonates within an intensive care setting. PROPOSED COMMERCIAL APPLICATION: NOT AVAILABLE
