Highly accurate intravenous (IV) flow rate control dedicated to mobile IV systems

尽管市面上用于静脉注射的输液泵取得了巨大进步，但目前，94%以上的住院患者仍然使用简单的重力驱动系统接受药物静脉注射。事实是，这种低成本的基于重力的静脉注射系统由于静脉注射容器中液体柱的体积/重量的变化或后者相对于患者体内输送接入点的高度的变化而遭受流速变化的影响。考虑到从恶劣条件中抢救出来的个人的生命支持管理，通过具有成本效益和易于使用的设备（也与所有类型的标准静脉输液袋兼容）安全输送“高风险”治疗药物更具挑战性。在这种情况下，IV系统应该适应更突然的操作条件变化，比如在使用飞机进行救援任务时救出伤者或昏迷者时遇到的情况。此外，静脉注射系统对-à-vis大小压力变化的稳健性是系统应该具备的一个关键特征，以便以高水平的竞争力进入市场。从这个角度来看，我们的目标是与我们的工业合作伙伴TrendyMED Inc.一起研究开发一种新型的基于袖带的流量控制系统，该系统可以无缝地结合自加压IV系统以及光电传感器和静电执行器。一个高精度的流量控制系统将为TrendyMed公司创造巨大的市场机会，提供一个新的美孚IV系统，并将其培养成为世界领先者之一

Despite great advances made in commercially available Infusion pumps for intravenously administered solutions, currently, more than 94% of hospitalized patients still receive medicated IVs using simple gravity-driven systems. The fact is, such low-cost gravity-based IV systems suffer from flow rate variations due to changes in the volume/weight of the liquid column in the IV container or changes in the elevation of the latter relative to the delivery access-point in the patient's body. The safe delivery of "high-risk" therapeutic agents through cost-effective and easy-to-use devices that are also compatible with all types of standard IV bags is even more challenging when considering the administration of life support to individuals rescued from harsh conditions. In such situations IV systems should adapt to even more abrupt changes in operating conditions like those met when extracting injured or comatosed during rescue missions using aircrafts. Also, robustness of IV administration systems vis-à-vis small and large pressure changes is a key feature that a system should have in order to reach the market with high level of competitiveness. In this perspective, and conjointly with our industrial partner, TrendyMED Inc. we aim to study the development of a novel cuff-based flow control system that seamlessly incorporates a self-pressurized IV system along with optoelectronic sensors and electrostatic actuators. A high precision flow control system will create great market opportunities for TrendyMed Inc. by offering a new Mobil IV system and will groom it to become one of the world leaders in the
