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

尽管用于静脉内给药溶液的市售输注泵取得了巨大进步，但目前，超过94%的住院患者仍然使用简单的重力驱动系统接受药物IV。事实是，这种低成本的基于重力的IV系统由于IV容器中的液柱的体积/重量的变化或IV容器相对于患者体内的输送接入点的高度的变化而遭受流速变化。当考虑到对从恶劣条件下获救的个人给予生命支持时，通过具有成本效益且易于使用的设备安全输送“高风险”治疗剂，并且这些设备还与所有类型的标准IV袋兼容，这甚至更具挑战性。在这种情况下，IV系统应该适应操作条件的更突然的变化，例如在使用飞机执行救援任务期间提取受伤或昏迷时遇到的情况。此外，IV给药系统维斯维斯小的和大的压力变化的稳健性是系统为了以高水平的竞争力进入市场而应该具有的关键特征。从这个角度来看，我们与我们的工业合作伙伴TrendyMED Inc.我们的目标是研究一种新型的基于袖带的流量控制系统的开发，该系统无缝地将自加压IV系统沿着与光电传感器和静电致动器结合。高精度的流量控制系统将为TrendyMed公司创造巨大的市场机会。通过提供一个新的美孚IV系统，并将培养它成为世界领先的

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
