I-Corps: Infrared camera based detection of subsurface veins

这个i-Corps项目的更广泛的影响/商业潜力源于红外线可视化技术的使用？S能够为医院和诊所的患者和医生提供一种经济高效的方法，以减少需要周围血管进入的手术期间的不适感。可视显示器的移动性和简单性还允许患者和医疗保健专业人员在传统机构的墙壁外以及在目前有限或无法访问它们的环境中使用相同的解决方案。据估计，错过血管进入尝试每年给美国医疗系统造成60亿美元的损失，患者满意度目前与联邦医疗保险报销挂钩。血管通路是医院最常见的预置程序之一，拟议的设备为这些设施提供了一个负担得起的机会，以提高广大患者群体的患者满意度。血库和献血中心依赖志愿者提供血液，而这类献血者的满意度对他们招募未来志愿者或重复献血者的能力至关重要。这些设施受到强烈激励，以提供尽可能积极的患者体验，从最大限度地减少血管进入尝试的次数开始。该设备还可以适用于非临床情况，如紧急情况或战场环境。这个I-Corps项目使用脱氧血液与近红外波长的光的独特相互作用，创建患者身体的实时视频馈送，周围血管系统与周围的真皮、动脉和脂肪组织明显区分开来。这使从业者能够观察静脉的物理位置，获得相对静脉深度的估计，并观察已知的混淆进入尝试的因素，如血管运动或滚动。这也允许在有身体特征或损伤的患者中找到更好的静脉位置，从而使血管更难进入。初步样机演示了所提出的声明，并已完成基本测试，以演示在各种环境中的功能。

The broader impact/commercial potential of this I-Corps project stems from the use of infra-red visualization technology?s ability to offer patients and medical practitioners at hospitals and clinics a cost-effective way to reduce discomfort during procedures requiring peripheral vascular access. The mobility and simplicity of the visual display also allow same solution to be used by patients and health care professionals outside the walls of traditional institutions, and in settings where there is currently limited or no access to them. Missed vascular access attempts are estimated to cost the U.S. healthcare system $6 billion dollars annually, and patient satisfaction is currently tied to Medicare reimbursement. Vascular access is one of the most frequently preformed procedures in hospitals, and the proposed device provides an affordable opportunity for those facilities to improve patient satisfaction across a broad patient population. Blood banks and donation centers rely on volunteers for their supply and the satisfaction of such donors is crucial to their ability to recruit future volunteers or repeat-donors. These facilities are strongly incentivized to provide as positive a patient experience as possible, starting with minimizing the number of vascular access attempts. The device can also be adapted for non-clinical situations, such as emergency or battlefield environments.This I-Corps project uses the unique interaction of deoxygenated blood with light at near infrared wavelengths to create a live, real time video feed of the patients body with the peripheral vasculature clearly differentiated from the surrounding dermal, arterial, and adipose tissue. This allows for practitioners to observe the physical location of the veins, get an estimate for relative vein depth, and observe factors that are known to confound access attempts, such as vascular movement or rolling. This also allows for superior vein location in patients with physical traits or impairments that make vascular access more difficult. A preliminary prototype demonstrates the claims made and rudimentary testing has been completed to demonstrate functionality in a variety of environments.
