OPTICAL DETECTION OF INTRAVENOUS INFILTRATION

在美国，大约80%的住院患者需要静脉注射治疗 50%的静脉输液管由于渗透、插管中的凝块、 静脉的炎症反应或插管与静脉分离。 IV浸润通常伴有疼痛、红斑和/或肿胀， 插管尖端或插入部位。严重浸润可能导致坏死 需要皮肤清创术、皮肤移植或截肢。早期发现 渗透防止了可能需要 手术矫正本研究的第一阶段目标是开发一种光学 检测IV渗透的技术，并证明 达到或优于目视和触觉检查的技术， 训练有素的观察员。在第一阶段，将开发一个原型装置， 将展示该技术的可行性。第一阶段研究将 包括对测量结果的分析以确定何时警告医疗保健 供应商和报警的方式。第二阶段的研究将包括 新生儿重症监护技术应用的调查 设置. 拟议商业应用：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
